Ossicular destruction is a common phenomenon in chronic otitis media due to an imbalance between osteoblasts and osteoclasts. Computed tomography helps us in the assessment of ossicular status, extent of pneumatization, and early identification of complications. This study aims to check the diagnostic accuracy of computed tomography temporal bone for the detection of ossicular erosion in comparison with the surgical findings taken as a gold standard. The use of this investigation as an adjunct can prove to be helpful in planning mastoid exploration as well as a primary reconstruction surgery especially in mucosal and early squamosal diseases. It's a cross-sectional validation study done on 50 patients with chronic otitis media (both mucosal and squamous type) from July 2022 to November 2023. Patients underwent CT scanning of temporal bone and ossicular status was reported by the radiologist. Later on, mastoid surgery was carried out and per operative findings were documented. 2 × 2 tables were formed and diagnostic accuracy of CT temporal bone was checked in terms of sensitivity, specificity, negative predictive value, and positive predictive value. The results revealed that CT temporal bone has a high diagnostic accuracy with a sensitivity of 92.5% and specificity of 100% for malleus ( value < 0.001). For incus and stapes, sensitivity came out to be 93.5% and 76% respectively and specificity values were 94.7% and 100% ( value < 0.001 for all) giving a verdict that the pre-operative use of this radiological investigation should be encouraged by otologists.

AIMS
In this study, we attempt to compare the pure tone audiometry findings with ossicular chain status intraoperatively in patients of chronic otitis media.
MATERIALS AND METHODS
102 patients who presented with COM during a period of one year and met the inclusion criteria were included in the study. All patients underwent preoperative pure tone Audiometry and findings were tabulated. All patients were evaluated intraoperatively by the same surgeon and observations were made regarding ossicular chain integrity.
RESULTS
Small central perforation was noted in 10%, medium central perforation in 38.57%, large central perforation in 27.14% and subtotal perforation in 24.28%. 71.56% patients had an intact ossicular chain, of which 94.5% was mucosal disease and 5.5% were squamous disease. 29 cases showed eroded/absent ossicles, out of which, 28 had squamous type and 1 case had central perforation. Ossicular status was classified based on Austin Classification. Conductive hearing loss was found to be maximum where all 3 ossicles were eroded/absent, with a mean AB gap of 45.33 and mean air conduction threshold of 60.33.
CONCLUSION
There is a good correlation between the hearing threshold of the patient and the status of ossicular chain. Preoperative knowledge of the degree of hearing loss and status of ossicular chain would allow the surgeon to plan proper ossicular reconstruction and give the patient a better advice regarding prognosis of hearing improvement after surgery.

Primary objective of this study was to compare the role of canalplasty in tympanoplasty, with that of only tympanoplasty, in patients of chronic suppurative otitis media with narrow external auditory canal and moderate to large central perforation, in terms of hearing improvement, graft uptake, intra operative ease. This study included 60 patients with chronic mucosal otitis media with narrow external auditory canal, with moderate to large central perforation, presenting to our institution from September 2019 to August 2021. Group A consisted of 30 patients, who underwent tympanoplasty with canalplasty and Group B consisted of 30 patients, who underwent tympanoplasty without canalplasty. Both the groups were followed up for 3 months, compared and analysed for hearing improvement and graft uptake. The results of our study indicated that Group A achieved 93.3% graft uptake rates compared to group B which achieved 80%. In Group A gain in air bone gap was 12.43 dB, whereas in Group B it was about 9.50 dB. Group A had significant hearing improvement and better graft uptake compared to Group B. It is advantageous to perform canalplasty prior to tympanoplasty in patients with narrow external auditory canal in whom the entire rim of annulus is not visible in one microscopic view. It yields better hearing improvement and graft uptake and prevents lateralization of the graft.

UNLABELLED
Chronic otitis media (COM) poses a significant global health burden, contributing to ear discharge and preventable hearing loss. This study aimed to evaluate the ossicular status in COM patients undergoing surgery and correlate the findings with preoperative otoscopic and audiogram assessments. The primary focus was to discern differences in ossicular involvement between squamous and mucosal diseases, shedding light on distinct pathologies crucial for tailoring surgical interventions. A total of 98 patients with COM (26 squamous disease, 72 mucosal disease) were included in the study. Analysis revealed the incus as the most commonly eroded ossicle, observed in 25 of 26 patients with squamous disease and 19 of 72 patients with mucosal disease. Conversely, the stapes exhibited remarkable resistance to erosion, remaining intact in 89 patients, with the stapes footplate found intact in all cases. Malleus erosion was observed in 13 patients categorized as "unsafe" and 6 patients in the "safe" category. Additionally, ossicular joints were more frequently eroded in squamous disease patients compared to those with mucosal disease. The study provides valuable insights into the distinct pathology of COM squamosal and COM mucosal cases, emphasizing the need for tailored surgical interventions to address the specific requirements of each patient group. By correlating operative findings with clinical findings, this research contributes to a deeper understanding of COM pathology, paving the way for more targeted and effective intraoperative ossicular reconstruction strategies.

BACKGROUND AND OBJECTIVES
Chronic suppurative otitis media (CSOM) is a chronic inflammation of the mucoperiosteal lining of the middle ear cleft, presenting with recurrent ear discharge through a tympanic membrane perforation. The present study aims to assess the spectrum of bacterial infection among CSOM cases and detect the isolated organism's antibiotic sensitivity pattern.
METHODS
The prospective hospital-based observational study was conducted from June 2021 to June 2022 and included 94 CSOM cases. An aural swab of the ear discharge was collected from each patient under aseptic precautions. The swab was utilized for Gram's staining and the aerobic bacterial pathogen culture. The organisms isolated were tested for antibiotic sensitivity using the Kirby-Bauer disc diffusion method.
RESULTS
The most affected age group was the second decade of life (27.7%, n=26), with a male-to-female ratio of 1.35:1. The mean duration of ear discharge was 24.0±14.7 months, mostly mucoid ear discharge (39.4%, n=37). Among gram-positive bacteria, methicillin-resistant was isolated in 16 (17.0%) cases. was the most isolated gram-negative bacteria strain in 26 (27.7%) cases. Cotrimoxazole (67.7%, n=21) had the highest sensitivity towards gram-positive bacteria isolates. Amongst gram-negative bacteria, amikacin and ciprofloxacin were the most sensitive, with 78.0% (n=39) susceptibility.
CONCLUSION
Evaluating the spectrum of infecting organisms of CSOM and their antibiotic sensitivity may help initiate prompt treatment with the appropriate antibiotic regimen, thereby preventing future complications.

Deficiency of adenosine deaminase 2 is a rare monogenic multi-organ disease of children and less often adults resulting from mutations in the adenosine deaminase 2 gene. We present a case of a 35-year-old Palestinian male with adenosine deaminase 2 deficiency and maturity-onset diabetes of the young type 2. The patient initially presented with complaints of swelling in his neck and night sweats, leading to a diagnosis of Hodgkin lymphoma. Subsequent evaluation revealed a recurrence of Hodgkin lymphoma, along with symptoms of otitis media, upper respiratory tract infection, and a rash around the mouth. Genetic testing confirmed mutations in the adenosine deaminase 2 gene and glucokinase genes, confirming the diagnosis of deficiency of adenosine deaminase 2 and maturity-onset diabetes of the young type 2, respectively. The patient was treated with Intravenous immunoglobulin, antiviral drugs, and oral hypoglycemic drugs, showing improvement in symptoms and laboratory tests. This case highlights the importance of considering rare genetic disorders in patients with unusual or refractory clinical manifestations, and the need for a multidisciplinary approach in such cases.

OBJECTIVE
Otitis media with effusion (OME) is a prevalent and costly disease, especially in children. This article analyzed the expression patterns and clinical significance of T helper-1 (Th1)/Th2 cytokines in the peripheral blood of children with OME and allergic rhinitis (AR).
METHODS
Subjects were assigned to the OME + AR group and the Control group (children with OME), with their clinical baseline data documented. The correlations between Th1/Th2 cytokines and between the total nasal symptom score (TNSS) and Th1/Th2 cytokines were analyzed. The risk factors and the predictive value of Th1/Th2 cytokines for OME + AR were analyzed using logistics multivariate regression analysis and receiver operating characteristic curve.
RESULTS
Significant differences were observed in tympanic pressure/speech frequency/air conduction valve/TNSS score/immunoglobulin E (IgE) level between both groups. The OME + AR children exhibited evidently elevated interleukin-2 (IL-2)/tumor necrosis factor-α (TNF-α)/IL-4/IL-10/IL-6 levels and no significant difference in interferon-γ (IFN-γ) level. Th1/Th2 cytokines were remarkably positively-correlated with the TNSS score. IL-2/TNF-α/IL-4/IL-6 were risk factors for OME with AR. The area under the curves (AUCs) of IL-6/IL-2/IL-4/TNF-α levels in predicting the occurrence of OME + AR were 0.805/0.806/0.775/0.781, with sensitivities of 75.76 %/89.39 %/72.21 %/72.73 % and specificities of 74.29 %/61.34 %/72.86 %/70.00 %, and the cut-off values were 239.600/20.300/29.880/34.800 (pg/mL). The AUC of their combination in predicting OME + AR was 0.955 (93.94 % sensitivity, 85.71 % specificity).
CONCLUSION
Th1/Th2 cytokine levels were imbalanced and obviously positively-correlated with the TNSS score in OME + AR children. IL-2, TNF-α, IL-4, and IL-6 levels had auxiliary predictive value in the occurrence of OME + AR.

Achondroplasia (ACH; MIM #100,800), caused by a heterozygous gain of function pathogenic variant in the fibroblast growth factor receptor 3 gene (FGFR3; MIM*134,934), is the most prevalent and most readily identifiable cause of disproportionate short stature that is compatible with life. In addition, individuals with achondroplasia face significant medical, functional, and psychosocial challenges throughout their lives. This study assessed associated morbidities in patients with achondroplasia at a single center in Turkey. In this study, the clinical findings and associated morbidities of a group of patients with achondroplasia (n = 68) with clinical multidisciplinary follow-up at a single center between the years 2005-2023 are evaluated retrospectively. A total of 68 patients, 30 male (44.1%) and 38 female (55.9%), were evaluated. In the majority (84.2%) of patients, shortness of extremities was detected in the prenatal period at an average of 28.7 gestational weeks (± 3.6 SDS) with the aid of ultrasonography. More than half (n = 34/63, 54%) of the patients had a father of advanced paternal age (≥ 35 years). Among the complications, respiratory system manifestations, including obstructive sleep apnea (70%), ear-nose-throat manifestations including adenoid hypertrophy (56.6%) and otitis media (54.7%), neurological manifestations due to foramen magnum stenosis (53.2%), and skeletal manifestations including scoliosis (28.8%), are represented among the most common. The mortality rate was 7.3% (n = 5/68).Conclusion: This study not only represents the first retrospective analysis of the associated morbidities of patients with achondroplasia from a single center in Turkey but also will provide a reference point for future studies.

OBJECTIVES
The 13-valent pneumococcal conjugate vaccine (PCV13) has been recommended for infants in Argentina's national immunization program (NIP) in a 2 + 1 schedule since 2012. Licensure of the 15-valent vaccine (PCV15) is anticipated soon, and the 20-valent vaccine (PCV20) recently received regulatory approval. This cost-effectiveness analysis examined the public health and economic implications of transitioning from PCV13 to either PCV15 or PCV20 in Argentina's pediatric NIP.
METHODS
A decision-analytic Markov model was used with a 10-year time horizon and a 3.0% annual discount rate for costs and benefits. Vaccine effectiveness estimates were derived from Argentinian surveillance data, PCV13 clinical effectiveness and impact studies, and PCV7 efficacy studies. Population, epidemiologic, and economic inputs were obtained from literature and Argentinian-specific data. The study adopted a healthcare system perspective; sensitivity and scenario analyses were conducted to assess input parameters and structural uncertainty.
RESULTS
Compared with PCV13, PCV20 was estimated to avert an additional 7,378, 42,884, and 172,389 cases of invasive pneumococcal disease (IPD), all-cause pneumonia, and all-cause otitis media (OM), respectively, as well as 3,308 deaths, resulting in savings of United States Dollars (USD) 50,973,962 in direct medical costs. Compared with PCV15, PCV20 was also estimated to have greater benefit, averting an additional 6,140, 35,258, and 142,366 cases of IPD, pneumonia, and OM, respectively, as well as 2,624 deaths, resulting in savings of USD 37,697,868 in direct medical costs. PCV20 was associated with a higher quality-adjusted life year gain and a lower cost (i.e., dominance) versus both PCV13 and PCV15. Results remained robust in sensitivity analyses and scenario assessments.
CONCLUSION
Over a 10-year horizon, vaccination with PCV20 was expected to be the dominant, cost-saving strategy versus PCV13 and PCV15 in children in Argentina. Policymakers should consider the PCV20 vaccination strategy to achieve the greatest clinical and economic benefit compared with lower-valent options.

INTRODUCTION
The purpose of this study was to investigate the prevalence of otitis media and other otolaryngologic disorders in children with Obstructive Sleep Apnea (OSA) compared to those without OSA in a large cohort.
METHODS
A retrospective cohort study was carried within the US Collaborative Network within TriNetX. The OSA group was defined by ICD-10 code G47.33 and non-OSA group excluded patients with OSA. Both groups were required to have a CPT code for an outpatient visit to act as a control: 99202-99215. Propensity score matching for age, sex, and race was performed. Prevalence of otitis media (ICD-10H65, H66), chronic otitis media (ICD-10H66.1, H66.2, H66.3, H65.2, H65.3, and H65.4), tympanostomy (CPT 69433, 69436), adenoidectomy (CPT 42830, 42831), tonsillectomy (CPT 42825, 42826), adenotonsillectomy (CPT 42820, 42821), and allergic rhinitis (ICD-10 J30.9) were compared in this cohort.
RESULTS
Propensity score matching yielded 165,665 (M = 95949, F = 69901) patients with a mean age of 10.7 (SD = 4.07) for each cohort. Children with OSA were 1.27x and 3.86x more likely to be diagnosed with otitis media and chronic otitis media, respectively (P<.0001). They were 3.81x more likely to undergo a tympanostomy (P<.0001). Children with OSA were 4.1x, 18.2x, and 24.7x more likely undergo an adenoidectomy, tonsillectomy, and adenotonsillectomy, respectively (P<.0001). Children with OSA were also 2.03x as likely to have a diagnosis of allergic rhinitis (P<.0001).
CONCLUSION
Children with OSA experience otitis media and related surgical intervention more than children without OSA. Since allergic rhinitis and adenoid hypertrophy are contributors to both OSA and AOM, their increased prevalence in children with OSA may explain their increased frequency of AOM.
