INTRODUCTION
This study aims to examine the long-term management of peritonsillar abscess and compare needle aspiration, incision with drainage, and tonsillectomy in terms of comorbidities, complication rates, and recurrences in the largest study cohort published to date.
METHODS
We conducted a retrospective analysis of patients, both adults and children, who were treated for peritonsillar abscess between 2007 and 2019. Patient charts were analyzed to assess surgical treatment, infection and inflammation rates, risk of bleeding, recurrence rates, duration of illness, and sick certificates. Additionally, patient imaging and blood levels were compared. Postal questionnaires were sent to all patients to evaluate subjective success rates, complications, and long-term benefits of the different treatment regimens. General practitioners and ENT doctors in private practices were contacted to gather missing data on the long-term course of the disease.
RESULTS
A total of 821 patients with peritonsillar abscess were included in this study. Two patients had to be excluded due to incidental pathological findings. Of the remaining 819 patients, 180 were successfully treated with needle aspiration or incision. Among these patients, 37.7% required tonsillectomy during the same inpatient stay. Laboratory parameters such as leukocyte count or C-reactive protein levels were not indicative of the need for tonsillectomy. Furthermore, computed tomography was only necessary in cases of suspected parapharyngeal abscess, not in clear cases of peritonsillar abscess. Among the 641 patients who underwent tonsillectomy, 11.4% experienced postoperative bleeding requiring treatment. Only patients who underwent bilateral tonsillectomy reported recurrent episodes of sore throat and pharyngitis resulting in absence from work. The ipsilateral recurrence rate for peritonsillar abscess after needle aspiration or incision was 2.8%. There were no contralateral recurrences during the observation period.
CONCLUSION
Due to the lower risk of postoperative bleeding, shorter absence from work, and shorter inpatient stay, incision and drainage are the preferable treatment for peritonsillar abscess. Additionally, patients who underwent bilateral tonsillectomy reported higher rates of work incapacity due to sore throat caused by pharyngitis. No patient met the clear indication for bilateral tonsillectomy due to recurrent acute tonsillitis. The recurrence rate after drainage without tonsillectomy was very low (2.8% ipsilaterally, no recurrence contralaterally).

Review
INTRODUCTION
This study assessed if the healthcare system overload and the organizational changes made in response to COVID-19 may be having an impact on clinical and epidemiological characteristics of the peritonsillar infection (PTI).
MATERIALS AND METHODS
In a retrospective longitudinal and descriptive follow-up, we reviewed the circumstances of the patients attended during 5 years, from 2017 to 2021, in two hospitals, one regional and other tertiary. Variables related to underlying pathology, history of tonsillitis, time of evolution, previous visits to Primary Care, diagnostic findings, abscess/phlegmon ratio, and length of hospital stay were recorded.
RESULTS
From 2017 to 2019, the incidence of the disease ranged between 14 and 16 cases/100,000 inhabitants-year, and decreased to 9.3 in 2020, a 43% less. Patients with PTI consulting in pandemic time were visited much less often in Primary Care services. They showed a greater severity of symptoms and the period of time between their appearance and diagnosis was longer. Additionally, there were more abscesses and the need for hospital admission greater than 24h was 66%. There was hardly a causal relationship with acute tonsillitis, although 66% of the patients evidenced history of recurrent tonsillitis, and 71% concomitant pathology. All these findings showed statistically significant differences with the pre-pandemic cases.
CONCLUSIONS
The protection of airborne transmission, the social distancing and the lockdown adopted in our country are measures that seem having been able to modify the evolution of PTI, with a much lower incidence, a longer recovery period and a minimal relationship with acute tonsillitis.

Although peritonsillar abscesses (PTAs) are a common presentation in pediatric patients, there are very few reports on a pediatric patient with both a PTA and uvular hydrops. Our patient presented to the emergency room after being unsuccessfully treated for pharyngitis, with odynophagia, dyspnea, muffled voice, drooling, and trismus. On physical examination, we observed a PTA as well as an edematous and erythematous uvula. Following the standard of care, the patient underwent a needle aspiration in the emergency department and subsequently was admitted overnight for observation. The patient had great symptom relief after undergoing drainage of his PTA and was discharged the next morning with symptom resolution of his dyspnea and odynophagia. We recommend drainage and close monitoring for airway compromise as an appropriate treatment course for PTAs and concurrent uvular hydrops.

Review
INTRODUCTION
Peritonsillar abscess (PTA) is a common condition with a complicated aetiology. PTA after tonsillectomy is rare. This literature review of PTA in the absence of tonsil tissue aims to collate experience of these cases and examine the wider implications for understanding the aetiology of PTA formation.
METHODS
A structured literature review was performed using Ovid MEDLINE®. Keywords 'quinsy' or 'peritonsillar abscess' were combined with 'tonsillectomy'.
RESULTS
The search resulted in 212 citations and the identification of 11 cases of PTA formation in the absence of tonsil tissue. The most common indication for tonsillectomy was recurrent tonsillitis or PTA. Nine patients had no interval peritonsillar infection (ie a peritonsillar infection after a tonsillectomy) prior to presenting with the PTA. The mean interval between tonsillectomy and PTA was 16 years. All patients were managed either by incision and drainage or by needle aspiration with or without antibiotics.
CONCLUSIONS
PTA in the absence of tonsil tissue is rare. Potential sources of infection include congenital branchial fistulas, Weber's glands and dental disease. These alternatives should also be considered in patients presenting with PTA formation in the absence of concurrent tonsillitis and may influence management decisions.

Review
Despite widespread use of antibiotics and surgical procedures for treating peritonsillar abscess (PTA), symptoms of severe inflammation such as pain and trismus during treatment result in patient dissatisfaction. The goal of this study was to perform a systematic review and meta-analysis of the efficacy of systemic steroids on the clinical course of PTA. Two reviewers independently searched the databases (MEDLINE, Scopus, and the Cochrane Database) from inception to December 2014. Studies comparing systemic administration of steroids (steroid group) with placebo (placebo group), where the outcomes of interest were pain, body temperature, hospitalization, and oral intake during the posttreatment period, were included. Baseline study characteristics, study quality data, numbers of patients in the steroid and control groups, and outcomes were extracted. Sufficient data for meta-analysis were retrieved for 3 trials with a total of 153 patients. Pain-related parameters (patient-reported scores and trismus), body temperature, and dysphagia during the first 24 hours after treatment were significantly improved in the steroid group compared with placebo group. The discharge rate during the first 5 days of the posttreatment period was significantly higher in the steroid group than the control group. However, although more patients in the steroid group returned to normal activities and dietary intake at 24 hours after treatment, the differences between the groups were not significant and disappeared after 48 hours. In the treatment of PTA, systemic administration of steroids with antibiotics could reduce pain-related symptoms, as well as provide a benefit with respect to the clinical course. However, further trials with well-designed research methodologies should be conducted to confirm our results.

Meta-Analysis Review
BACKGROUND
Peritonsillar abscess is a common infection presenting as a collection of pus in the peritonsillar area. The condition is characterised by a severe sore throat, difficulty in swallowing and pain on swallowing, fever and malaise, and trismus. Needle aspiration and incision and drainage are the two main treatment modalities currently used in the treatment of this condition. The effectiveness of one versus the other has not been clearly demonstrated and remains an area of debate.
OBJECTIVES
To assess the effectiveness and risks of needle aspiration versus incision and drainage for the treatment of peritonsillar abscess in older children (eight years of age or older), adolescents and adults.
SEARCH METHODS
The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2016, Issue 7); Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 25 August 2016.
SELECTION CRITERIA
Randomised controlled trials comparing needle aspiration with incision and drainage.
DATA COLLECTION AND ANALYSIS
We used the standard methodological procedures expected by Cochrane. Our primary outcomes were recurrence rate (proportion of patients needing repeat intervention) and adverse effects associated with the intervention. Secondary outcomes were time to resumption of normal diet, complications of the disease process and symptom scores. We used GRADE to assess the quality of evidence for each outcome; this is indicated in italics.
MAIN RESULTS
We included 11 studies (674 participants). The risk of bias was high or unclear in all of the included studies. All studies compared needle aspiration to incision and drainage.All but one of the 11 studies reported on the primary outcome of recurrence. When we pooled data from the 10 studies the recurrence rate was higher in the needle aspiration group compared with incision and drainage: risk ratio (RR) 3.74 (95% confidence interval (CI) 1.63 to 8.59; 612 participants). We detected moderate heterogeneity in this analysis (I = 48%). In interpreting the pooled result it is important to note that the evidence for this outcome was of very low quality.None of the other outcomes (adverse effects of the intervention, time to resumption of normal diet, complications of the disease process and symptom scores) were consistently measured across all studies.Only three studies reported on adverse effects/events associated with the intervention and only one such event in a single patient was reported (post-procedure bleeding following incision and drainage: 1/28, 3.6%) (very low-quality evidence). Time to resumption of normal diet was compared in two studies; neither found an obvious difference between needle aspiration and incision and drainage (very low-quality evidence).Only three studies stated that they would report complications of the disease process. In these three studies, the only complication reported was admission to hospital for dehydration in two patients who underwent incision and drainage (2/13, 6.7%). Symptom scores were measured in four studies; three evaluated pain using different scales and one other symptoms. The data could not be pooled in a meta-analysis. Two studies evaluating procedural pain reported this to be lower in the needle aspiration groups. One study found comparable rates of pain resolution at five days post-intervention between groups. The quality of the evidence for symptom scores was very low.
AUTHORS' CONCLUSIONS
Although a number of studies have sought to evaluate whether or not needle aspiration or incision and drainage is more effective in patients with peritonsillar abscess, there is no high-quality evidence to allow a firm conclusion to be drawn and the answer remains uncertain. Very low-quality evidence suggests that incision and drainage may be associated with a lower chance of recurrence than needle aspiration. There is some very low-quality evidence to suggest that needle aspiration is less painful.

Meta-Analysis
BACKGROUND
Sore throat is a common condition associated with a high rate of antibiotic prescriptions, despite limited evidence for the effectiveness of antibiotics. Corticosteroids may improve symptoms of sore throat by reducing inflammation of the upper respiratory tract. This review is an update to our review published in 2012.
OBJECTIVES
To assess the clinical benefit and safety of corticosteroids in reducing the symptoms of sore throat in adults and children.
SEARCH METHODS
We searched CENTRAL (Issue 4, 2019), MEDLINE (1966 to 14 May 2019), Embase (1974 to 14 May 2019), the Database of Abstracts of Reviews of Effects (DARE, 2002 to 2015), and the NHS Economic Evaluation Database (inception to 2015). We also searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that compared steroids to either placebo or standard care in adults and children (aged over three years) with sore throat. We excluded studies of hospitalised participants, those with infectious mononucleosis (glandular fever), sore throat following tonsillectomy or intubation, or peritonsillar abscess.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
We included one new RCT in this update, for a total of nine trials involving 1319 participants (369 children and 950 adults). In eight trials, participants in both corticosteroid and placebo groups received antibiotics; one trial offered delayed prescription of antibiotics based on clinical assessment. Only two trials reported funding sources (government and a university foundation). In addition to any effect of antibiotics and analgesia, corticosteroids increased the likelihood of complete resolution of pain at 24 hours by 2.40 times (risk ratio (RR) 2.4, 95% confidence interval (CI) 1.29 to 4.47; P = 0.006; I² = 67%; high-certainty evidence) and at 48 hours by 1.5 times (RR 1.50, 95% CI 1.27 to 1.76; P < 0.001; I² = 0%; high-certainty evidence). Five people need to be treated to prevent one person continuing to experience pain at 24 hours. Corticosteroids also reduced the mean time to onset of pain relief and the mean time to complete resolution of pain by 6 and 11.6 hours, respectively, although significant heterogeneity was present (moderate-certainty evidence). At 24 hours, pain (assessed by visual analogue scales) was reduced by an additional 10.6% by corticosteroids (moderate-certainty evidence). No differences were reported in recurrence/relapse rates, days missed from work or school, or adverse events for participants taking corticosteroids compared to placebo. However, the reporting of adverse events was poor, and only two trials included children or reported days missed from work or school. The included studies were assessed as moderate quality evidence, but the small number of included studies has the potential to increase the uncertainty, particularly in terms of applying these results to children.
AUTHORS' CONCLUSIONS
Oral or intramuscular corticosteroids, in addition to antibiotics, moderately increased the likelihood of both resolution and improvement of pain in participants with sore throat. Given the limited benefit, further research into the harms and benefits of short courses of steroids is needed to permit informed decision-making.

OBJECTIVE
There are no consensus guidelines for managing peritonsillar abscess (PTA) despite its prevalence. In order to devise best practice guidelines, current practice patterns must first be established.
METHODS
This was a cross-sectional study, surveying Otolaryngology-Head & Neck Surgery trainees (residents and fellows) and consultant (academic and community). The primary outcome was the type and duration of outpatient antibiotic prescription. Secondary outcomes included differences in workup, management, prescription, and follow-up.
RESULTS
There were 57 respondents to the survey; 24 (42%) trainees (residents/fellows) and 33 (58%) consultants. On average, each respondent managed an average of 15.2 (SD 11.2) PTAs within the last year. All respondents prescribed oral antibiotics, with amoxicillin-clavulanic acid being the most common (61%). Trainees prescribed amoxicillin-clavulanic acid more often than consultants (n = 21, 88% vs n = 14, 42%, = .0084), respectively. Duration of antibiotic therapy ranged from 5 to 14 days. Most commonly, a 10-day course of antibiotics was prescribed (n = 31, 54%). Regarding the management of PTAs, a majority of respondents requested blood work (n = 39, 68%), performed needle aspiration (n = 42, 72%) and performed incision and drainage (n = 52, 91%). Culture and sensitivity of the aspirate/drainage fluid was frequently performed (n = 41, 72%). Patients were often provided non-opioid analgesics (n = 46, 81%), but more than half still received prescription opioids (n = 36, 63%). The majority of clinicians arranged for follow-up (n = 42, 74%), most often with Otolaryngology - Head & Neck Surgery (n = 27, 64%), with an average follow-up of 12.5 (SD 8.2) days.
CONCLUSION
We found heterogeneity in the management of PTAs, with variability in the outpatient antibiotic prescription. This study highlighted the wide range of management strategies employed along with differences in workup, investigation, post-discharge analgesic prescription, and follow-up arrangements.

INTRODUCTION
The peritonsillar space is defined as the area between the palatine tonsillar capsule medially and the superior pharyngeal constrictor muscle laterally. Unilateral peritonsillar abscess (PTA) is more common than the bilateral condition. To the best of our knowledge, only 13 cases of bilateral PTA have been reported worldwide; this is the first case reported from Saudi Arabia.
PRESENTATION OF CASE
We present a case involving a 16-year-old boy who presented to the emergency department with a5-day history of sore throat, dysphagia, trismus, drooling, and a muffled "hot-potato" voice, but with no symptoms of airway compromise. After several examinations, we diagnosed bilateral PTA. We performed an incision and drained the pus from both sides, which was positive for Streptococcus pyogenes. Postoperatively, the patient improved dramatically, and tonsillectomy was scheduled for 6 weeks later.
DISCUSSION
The difficulty in diagnosing bilateral PTA stems from the fact that it does not present with the usual clinical characteristics as unilateral PTA. These symptoms include asymmetry of the tonsils and palate, deviation of the uvula, and unilateral otalgia. As these cases carry the risk of impending airway compromise, we recommend airway management as the first step in treating such cases.
CONCLUSION
Based on our case and literature review, we recommend airway management as the first step, followed by further examinations, especially contrast-enhanced computed tomography, in cases of bilateral PTA. This condition lacks the hallmark of unilateral disease and may mimic many conditions, which will have different management approaches.

AUDIENCE
Our reusable low-cost peritonsillar abscess simulator (PTA) simulator is designed to train emergency medicine (EM) residents, fellows, and medical students. Trainees who are interested in otolaryngology (OTL) or this specific disease may also benefit from this simulator.
INTRODUCTION
Peritonsillar abscess is one of the most common deep infections 1 of the head and neck, accounting for 7589 consultations and 11069 hospital bed days in the UK between 2009-2010.1,2 Emergency medicine physicians commonly treat this pathology with surgical and medical modalities. Not only is this a common diagnosis, but there is a significant cost associated with the evaluation and management of primary PTA. 3Demands for high-volume patient care and good patient outcomes are increasing in a medical climate of limited financial resources and resident work hours. Given these complexities, medical education is viewing simulation training, with proven success in various surgical specialties, as a valuable addition to resident education and patient safety. 3-5The PTA is the collection of pus in the space between the palatine tonsil and its capsule. Successfully locating the abscess is crucial because it prevents the unwanted damage of nearby vascular structures, patient discomfort, and failure to treat the infection. Management of peritonsillar abscess is primarily surgical and includes incision and drainage (I & D), needle aspiration, or Quinsy tonsillectomy.The simulator provides a realistic characteristic of typical PTA presentations, such as uvula deviation, swelling, trismus, and purulence during aspiration. While learning to drain a PTA, trainees must locate the infection with a needle without injury to the surrounding structures of the oral cavity and deep structures of the neck. The discomfort caused during this procedure can be unsettling for both physician and patient. Simulation use and testing enable the trainee to develop familiarity with handling instruments, increase comfort with the sequence of a procedure, and improve confidence in the ability to perform a procedure safely.6,7,8 Simulators provide improved patient outcomes and increased EM residents' comfort level.
EDUCATIONAL OBJECTIVES
By the end of this training session, learners will be able to: 1) locate the abscess, 2) perform needle aspiration, and 3) develop dexterity in maneuvering instruments in the small three-dimensional confines of the oral cavity without causing injury to local structures.
EDUCATIONAL METHODS
Our PTA simulator was fabricated with a low-cost, non-degradable material and is the first known PTA simulator that used a validated survey for fidelity assessment. The simulator was fabricated using a silicone mold to mimic the oral cavity and oropharynx. A simulated abscess pocket consisting of saline encased in balloon material was placed in the proper anatomic location, allowing for abscess simulation on either side of the oropharynx model. The time to fabricate the model averaged 20 hours. The simulator was manufactured with low-cost materials at an expense of 45 USD and could be easily reproduced by any EM residency program.
RESEARCH METHODS
Twenty-one participants were instructed to expose and drain the simulated abscess. The model was evaluated using The Michigan Standard Simulation Experience Scale (MiSSES).7 Participants scored the simulator in five categories: Self-efficacy, fidelity, educational value, teaching quality, and the overall rating on a 5-point Likert scale of simulator. Overall rating and global evaluation scores were compared by groups (Group 1, Group 2) between training level (residents and attendings), specialty (emergency and otolaryngology), and previous experience (<5 or ≥5 drainages).Convenience sampling was used to determinate the sample. Variables were summarized using the mean and standard deviation for continuous variables and percentages and frequencies for categorical variables. The MiSSES was scored as previously described in the literature.7 The Kolmogorov-Smirnov test was used to test for normal distribution of the variables. T-test for independent samples was performed to determinate if there exists a difference between groups in perception of a PTA simulator. The statistical analyses were performed using SPSS version 20.0 Armonk, NY: IBM.
RESULTS
Twenty-one participants were enrolled in the study: residents (n=15) and attending (n=6) from OTL and EM departments. The simulator's plasticity allowed multiple attempts of needle aspiration and drainage without degradation and received high ratings on teaching quality, fidelity, and educational value. This PTA simulator achieved high fidelity ratings in the standard simulator's assessment survey for realism of environment, simulation of trismus, uvular deviation, and realism of the mucosal surfaces. On the MiSSES, the model received positive ratings (range 3.6 to 4.9). The highest rating was on teaching quality (4.9), fidelity (4.6), and educational value (4.5) (Table 1). We found that self-efficacy and teaching quality sections were rated higher for those who had less experience (≥5 PTA drainage), while fidelity was rated higher for OTL. The overall rating average was 4 and was higher of attendings, OTL, and those with less experience. All comparisons between groups were not statically significant (Table 2). About 76% of participants found that the simulator can be used in training with slight improvement or no improvement needed. (Table 3).
DISCUSSION
With favorable participant ratings and comments, we believe that this tool can offer high-fidelity simulation at a low cost. Widespread use may be possible, allowing training of EM residents in performing instrumentation of PTA in a controlled simulation environment. We have created a reusable low-cost PTA simulator that achieved a high score fidelity in a standard simulator's assessment survey.
