BACKGROUND
In individuals with nasal septal deviation (NSD), compensatory hypertrophy of the nasal turbinates occurs as a protective mechanism of the nasal passage from dry and cold air. NSD associated nasal turbinate hypertrophy is usually recurrent, requiring repetitive imaging. Therefore, a multiplanar imaging modality with a low radiation dose is best suited for long-term follow-up of this condition. This study aimed to evaluate the association of width of inferior turbinates and presence of concha bullosa with the degree of NSD using Cone beam computed tomography (CT).
METHODS
The CBCT scans of 100 patients with NSD were selected as per convenience sampling and were evaluated by two maxillofacial radiologists. The width of the non-hypertrophied inferior turbinate (NHT) on the convex side of the NSD, and hypertrophic inferior turbinates (HT) on the concave side of the NSD were measured at three locations. The septal deviation angle (SDA) and the presence of concha bullosa (CB) were determined.
RESULTS
A significant difference was observed in the anterior, middle, posterior, and mean widths between HT and NHT (p < 0.001). There was a significant difference in the widths of the HT and NHT among different types of NSD. A strong positive correlation (r = 0.71, p < 0.001) was found between SDA and the mean width of the HT. Age (P = 0.71) and gender (P = 0.65) had no significant difference among different types of NSD. Regression analysis revealed that the presence of CB (p = 0.01) and middle width of the HT (p < 0.001) are significant predictors of SDA and type of NSD.
CONCLUSION
The results of the present study reveal that the middle width of the HT and the presence of CB influence the degree of NSD. The present study results recommend the use of CBCT as a substitutive low radiation dose imaging modality for evaluation of NSD, CB, and associated inferior turbinate hypertrophy.

Efficacy and safety of a hypertonic nasal wash solution containing sea algae extracts in patients that underwent surgical correction of a deviated nasal septum and radiofrequency turbinate volume reduction.
OBJECTIVE
The objective of this study was to evaluate efficacy and safety of a Hypertonic Seawater Solution (2.3% NaCl) containing brown and blue-green Algae (HSS-A) in comparison to Isotonic Saline Solution (ISS) regarding the improvement of nasal breathing in patients that have undergone surgical correction of a deviated nasal septum and radiofrequency turbinate volume reduction.
PATIENTS AND METHODS
A total of 101 individuals were enrolled in the study (HSS-A: 57; ISS: 44). Nasal breathing was evaluated using a Peak Nasal Inspiratory Flow (PNIF) measurement device at four timepoints: prior to surgical intervention (up to 30 days pre-surgery) and at the 2nd, 10th and 20th postoperative days. On the 20th postoperative day, patients also answered a Nasal Surgical Questionnaire (NSQ) evaluating breathing ability and overall satisfaction from the use of both nasal sprays.
RESULTS
No significant differences were observed in PNIF measurements between groups at different points. On the 20th postoperative day, NSQ analysis showed that ISS-treated patients had more frequently moderate nasal bleeding compared to the HSS-A group (85.7% vs. 14.3%, p=0.038). No other statistically significant differences were observed between groups. When NSQ parameters were evaluated in a binary mode, a trend for reduced crusting scores was seen in the HSS-A group (15.9% vs. 35.5% in ISS, p=0.053). No safety concerns were reported throughout the study.
CONCLUSIONS
In patients that have undergone surgical correction of a deviated nasal septum and radiofrequency turbinate volume reduction, PNIF values did not differ significantly in patients receiving HSS-A and ISS solutions. Nasal bleeding was more frequent in ISS patients versus HSS-A. Overall, both solutions provided symptomatic relief and use satisfaction in the absence of side effects.

Surgical treatments for nasal airway obstruction (NAO) are commonly offered as part of otolaryngology practice. Anatomic causes include septal deviation, inferior turbinate hypertrophy, and nasal valve collapse (NVC). This study was performed to determine the prevalence of anatomic contributors to NAO. A total of 1,906 patients with sinonasal complaints were surveyed by 50 otolaryngologists in varying U.S. geographic regions. Patients were first evaluated using the Nasal Obstruction Symptom Evaluation (NOSE) instrument to assess the NAO symptoms and their severity. Physicians then examined patients for the presence of the three anatomic contributors. Presence of septal deviation and turbinate hypertrophy was assessed through an internal nasal exam with direct or endoscopic visualization based on the physician's standard methodology for diagnosis. Presence of NVC was determined by the modified Cottle maneuver. Among all patients surveyed, prevalence was 67% for NVC, 76% for septal deviation, and 72% for inferior turbinate hypertrophy. We found that 64% of the patients (n = 1,211) had severe/extreme NOSE scores (≥55), representing the most likely nasal obstruction candidates for intervention. In these patients, the prevalence of NVC, septal deviation, and inferior turbinate hypertrophy was 73, 80, and 77%, respectively. Eighty-two percent of the 236 patients with severe/extreme NOSE scores who reported prior septoplasty and/or inferior turbinate reduction had NVC. Our study revealed a comparable prevalence of all three anatomic contributors across all patients and the subset with severe/extreme NOSE scores, highlighting the importance of evaluating the lateral nasal wall as a component of NAO treatment strategy.

AIMS
Endoscopic modified transseptal bi-nostril approach minimizes turbinate and olfactory mucosal invasion and ensures preservation of the turbinates and bilateral olfaction. The main objective of this study was to investigate the pre- and postoperative variations in olfactory function in patients using this approach, and the secondary objective was to investigate the complications associated with the surgical procedure.
MATERIAL AND METHODS
This study is a single-center prospective cohort study using STROBE analysis. To completely protect the bilateral turbinates and olfactory epithelium, this procedure provided access to the sphenoid sinus by a transseptal approach via the left nasal cavity and by the olfactory cleft approach via the right nasal cavity without any turbinate resection. A T&T olfactometer was used to assess the mean recognition threshold of the left, right, and bilateral nasal passages before and after surgery, and complications associated with the surgical approach were investigated.
OBJECTIVES
We included 27 patients who underwent endoscopic modified transseptal pituitary surgery with an olfactory and turbinate preservation approach at our hospital between April 2018 and December 2019.
RESULTS
The mean postoperative recognition threshold of the right, left, and bilateral nasal cavities did not worsen (P<0.001 for all) relative to the preoperative values, and there was no difference in values between the right and left nasal cavities (P=0.85). The nasal turbinates were preserved in all patients during the study period, and no recurrence was observed.
CONCLUSION
Our modified EETSA could be implemented as an approach for turbinate and olfaction preservation.

The objective of this study was to investigate the effects of nasal valve area, valve stiffness, and turbinate region cross-sectional area on airflow rate, nasal resistance, flow limitation, and inspiratory "hysteresis" by the use of a mathematical model of nasal airflow. The model of O'Neill and Tolley ( 13: 273-277, 1988) describing the effects of valve area and stiffness on the nasal pressure-flow relationship was improved by the incorporation of additional terms involving ) airflow through the turbinate region, ) the dependence of the flow coefficients for the valve and turbinate region on the Reynolds number, and ) effects of unsteady flow. The model was found to provide a good fit for normal values for nasal resistance and for pressure-flow curves reported in the literature for both congested and decongested states. Also, by showing the relative contribution of the nasal valve and turbinate region to nasal resistance, the model sheds light in explaining the generally poor correlation between nasal resistance measurements and the results from acoustic rhinometry. Furthermore, by proposing different flow conditions for the acceleration and deceleration phases of inspiration, the model produces an inspiratory loop (commonly referred to as hysteresis) consistent with those reported in the literature. With simulation of nasal flaring, the magnitude of the loop, the nasal resistance, and flow limitation all show change similar to that observed in the experimental results. The present model provides considerable insight into some difficult conundrums in both clinical and technical aspects of nasal airflow. Also, the description of nasal airflow mechanics based on the Hagen-Poiseuille equation and Reynolds laminar-turbulent transition in long straight tubes, which has figured prominently in medical textbooks and journal articles for many years, is shown to be seriously in error at a fundamental level.

Leiomyosarcoma (LMS) in the sinonasal tract (SNT) is a rarity that has been firstly described in 1958. Since then, there have been only a few articles about this entity. Most of the data available about LMS in the SNT is derived from case reports. We believe that our case will support the data set and help guiding the management of this rare condition. A 84-year-old female presented with nasal airway obstruction on the left side. She experienced several episodes of epistaxis from her left nostril, what made her to seek medical care. A rhinoscopy revealed an obstructing mass in the left nasal cavity. Computed tomography (CT) scan of the paranasal sinuses revealed a homogenous mass occupying the left nasal cavity, bone destruction of the left middle, and inferior nasal turbinates. An infiltration of the left nasolacrimal duct was also present. The patient refused to undergo open surgery and the mass was removed during an endoscopic approach. The histopathological analysis combined with immunohistochemistry was consistent with LMS. The resection margins were positive for tumor cells. A staging with CT-neck-thorax, abdomen ultrasound, and MRI of the head ruled out metastases. She underwent a second endoscopic tumor resection surgery with positive resection margins and obtained adjuvant radiotherapy. On 9 months of follow-up, there was no recurrence or metastases.

Concha bullosa is the most frequently encountered anatomical variation of the lateral nasal wall characterised with pneumatisation of the middle concha. The incidence of middle concha bullosa varies between 14% and 53%. Patients may often complain of nasal congestion and may in some cases suffer episodes of recurrent acute rhinosinusitis. In this article we present a case of nasal obstruction with an unusually large concha bullosa.

This case study demonstrates a 58-year-old female who contracted COVID-19 post-vaccination presenting with severe left-sided facial pain, headaches, and dyspnea. A computed tomography was ordered and showed acute sinusitis, and upon bedside endoscopy, the patient was shown to have necrosis of the left-sided middle turbinate with no discoloration, palate necrosis, or facial changes. All samples of the necrotic tissue were reported to be invasive fungal sinusitis. The entire turbinate was resected in the operating room and ethmoid, frontal, and maxillary sinuses were healthy. Chest x-rays post-operatively showed pulmonary effusions and edema although the patient was not stable enough for a lung examination to rule out a pulmonary fungal infection. A bedside endoscopy showed no further necrosis post-operatively although a repeat endoscopy showed duskiness at the lateral attachment of the basal lamella right at the most posterior resection of the middle turbinate. The patient was placed on multiple antifungal agents. The patient remained in hypoxemic respiratory failure and septic shock while on pressors and 2 weeks following this, expired. Post-COVID-19 patients have been shown in the literature to have an increased risk of developing invasive fungal sinusitis (IFS) and all IFS cases during active COVID-19 infection have had a 100% mortality rate.

Meta-Analysis
IMPORTANCE
Turbinate surgery is an effective treatment for allergic rhinitis (AR) refractory to medical treatment. However, the long-term outcomes of turbinate surgery are still unclear and have not yet been confirmed by a meta-analysis and systematic review of the literature.
OBJECTIVE
To investigate the long-term outcomes and safety of turbinate surgery in AR by performing a meta-analysis.
DATA SOURCES
MEDLINE, Embase, the Cochrane Library, and ClinicalTrials.gov were searched through April 2021.
STUDY SELECTION
Studies that analyzed turbinate surgery alone, had a follow-up period of more than 1 year, examined long-term efficacy of turbinate surgery, used current turbinate surgery methods, and were published in a peer-reviewed journal were included. Full-text reviews were performed by 2 independent reviewers. Conflicts were resolved by a third reviewer.
DATA EXTRACTION AND SYNTHESIS
Descriptive and quantitative data were extracted; weighted mean difference (WMD) was synthesized under a random-effects model. Heterogeneity was assessed using the Q statistic and the I2 metric. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines.
MAIN OUTCOMES AND MEASURES
The long-term outcomes of turbinate surgery on subjective nasal symptoms and objective parameters.
RESULTS
Of the 3962 citations retrieved, 18 studies comprising 1411 patients were included. Findings showed significantly decreased symptom scores in nasal obstruction (WMD, 4.60, 95% CI, 3.43-5.76), rhinorrhea (WMD, 3.12; 95% CI, 1.97-4.28), sneezing (WMD, 2.64; 95% CI, 1.74-3.54), itching (WMD, 1.75; 95% CI, 1.20-2.30), and nasal resistance (WMD, 0.16; 95% CI, 0.08-0.24) and a significant increased total nasal volume (WMD, 0.96; 95% CI, 0.73-1.19). There was no significant difference in the occurrence of any complication. More than 1 year after surgery, the improvements in nasal obstruction (WMD, 5.18; 95% CI, 3.00-7.37), rhinorrhea (WMD, 3.57; 95% CI, 1.78-5.37), and sneezing (WMD, 2.95; 95% CI, 1.58-4.32) were maintained.
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis, turbinate surgery was associated with positive outcomes in AR and maintained the association during long-term follow-up. The rate of complications is also low. These findings can guide the preoperative counseling of patients with AR being considered for turbinate surgery.

Review
The causal relation between anatomical variations of the nose and headaches and facial pain is analyzed through literature review of the topic. The pathogenesis that can be involved in this relation proves to be wider than simple alteration of nasal septum and turbinates that can cause mechanical stimulus through contact between these structures, which covers infectious factors, neurogenic inflammation, correlation with migraines and the role of nasal obstruction. The clinical findings of a lot of authors including the test with topical anesthetic to prove this causal relation, the indication of surgical treatment, in addition to good results of this treatment, are reported. The mechanism of pain relief obtained through surgical correction of nasal septum and turbinate is discussed. These data make us conclude that there are multiple etiologic factors involved, which makes us question the fundamental role of the mechanical aspect.
