Background and Objectives: We investigated the effects of using a BiZact™ device for tonsillectomy on operating time, intraoperative blood loss, postoperative bleeding rate, and pain through a meta-analysis of the relevant literature. Materials and Methods: We reviewed studies retrieved from the databases of PubMed, SCOPUS, Google Scholar, Embase, Web of Science, and Cochrane up to March 2024. The results were analyzed following PRISMA guidelines. Six studies that compared the outcomes of patients receiving perioperative BiZact™ tonsillectomy with those in control groups (cold steel dissection or bipolar tonsillectomy) were included for this analysis of the outcomes, which included intraoperative bleeding and time, postoperative pain, and frequency of postoperative bleeding. Results: The operative time (SMD −11.5985, 95%CI [−20.3326; −2.8644], I2 = 99.5%) in the treatment group was significantly reduced compared to the control group. However, BiZact™ showed no significant efficacy in reducing intraoperative bleeding when compared with the control group (SMD −0.0480, 95%CI [−1.8200; 1.7240], I2 = 98.6%). Postoperative pain on day 1 (SMD −0.0885, 95%CI [−0.4368; 0.2598], I2 = 98.9%), day 3 (SMD −0.2118, 95%CI [−0.6110; 0.1873], I2 = 99.5%), and later than day 7 (SMD 0.0924, 95%CI [−0.2491; 0.4338], I2 = 98.6%) in the treatment group was not significantly reduced relative to the control group. When compared to the control group, BiZact™ did not reduce the incidence of secondary postoperative bleeding control in the operation room (OR 0.5711, 95%CI [0.2476; 1.3173], I2 = 32.1%), primary bleeding (OR 0.4514, 95%CI [0.0568; 3.5894], I2 = 0.0%), or all postoperative bleeding events (OR 0.8117, 95%CI [0.5796; 1.1368], I2 = 26.3%). Conclusions: This study demonstrated that using the BiZact™ device for tonsillectomy significantly decreased the operative time but could not effectively reduce intraoperative bleeding or postoperative pain and bleeding.

Summary: Although understanding the physiological mechanisms of obstructive sleep apnea (OSA) is important for treating OSA, limited studies have examined OSA patients' sleep architecture at the epoch‐by‐epoch level and analysed the impact of sleep position and stage on OSA pathogenesis. The epoch‐labelled polysomnogram was analysed multidimensionally to investigate the effect of sleep position on the sleep architecture and risk factors of apnea in patients with OSA. This retrospective multicentric case–control study reviewed full‐night diagnostic polysomnography of 6983 participants. The difference in the proportion of time spent supine during non‐rapid eye movement (NREM) and REM stages, and the mean duration of respiratory events per body position were evaluated. The frequency of sleep stage transition per body position shift type was computed. Further subgroup analysis was performed based on OSA severity and positional dependency. Supine time in patients with OSA varied across sleep stages, with lower proportions in N3 and REM, and shorter durations with severity. Patients with OSA spent less time in supine positions during N3 and REM, and experienced longer apnea events in both positions compared to the control group. The frequency of all sleep stage transitions increased with OSA severity and was higher among non‐positional OSA than positional OSA and the control group, regardless of body position shift type. The sleep stage transition from N3 and REM to wakefulness was notably heightened during position shift. Understanding the sleep architecture of patients with OSA requires analysing various sleep characteristics including sleep position simultaneously, with future studies focusing on position detection to predict sleep stages and respiratory events.

Background: We investigated the role of perioperative intraoral glossopharyngeal nerve block to minimize postoperative pain in patients undergoing tonsillectomy through a meta‐analysis of the relevant literature. Methods: We retrieved eight studies from PubMed, Scopus, Embase, Web of Science, and Cochrane databases up to August 2023. We compared perioperative glossopharyngeal nerve block with a control group, in order to examine postoperative pain, analgesic use, and other postoperative morbidities. Results: Postoperative pain was significantly reduced at 1–4 h (SMD −1.26, 95% CI [−2.35; −0.17], I2 = 94.7%, P = 0.02) and 5–8 hours (SMD −1.40, 95% CI [−2.47; −0.34], I2 = 96.1%, p = 0.01) in the treatment groups compared to the control group. However, glossopharyngeal nerve block showed no efficacy in reducing pain or use of analgesic drugs after 12 h compared to the control group. The incidences of postoperative bleeding (OR 0.95, 95% CI [0.35; 2.52], I2 = 0.0%), local agent toxicity (OR 4.14, 95% CI [0.44; 38.63], I2 = 0.0%), nasal problems (OR 1.25, 95% CI [0.60; 2.61], I2 = 0.0%), postoperative nausea and vomiting (OR 1.35, 95% CI [0.78; 2.33], I2 = 0.0%), swallowing difficulty (OR 1.61, 95% CI [0.76; 3.42], I2 = 56.0%), and voice change (OR 3.11, 95% CI [0.31; 30.80], I2 = 0.0%) were not significantly different between the treatment and control groups. The treatment group showed higher prevalence of respiratory problems and dry mouth compared to control without statistical significance, but a significant increase in throat discomfort (p = 0.02). Conclusion: Intraoral glossopharyngeal nerve block for tonsillectomy did not significantly impact postoperative pain management and was associated with some adverse effects with increases in respiratory problems, dry mouth, and throat discomfort compared to controls.

Objectives: This study assessed the impact of cryoablation of the posterior nasal nerve on symptoms of rhinitis in individuals with allergic rhinitis (AR) and non‐allergic rhinitis (NAR). Data Sources: PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases for studies published up to June 2023. Review Methods: Studies that evaluated the quality of life and rhinitis‐related symptom scores before and after cryotherapy treatment, as well as sham‐controlled studies, were included. Results: In total, 368 patients from seven studies were analyzed. Patients who underwent cryoablation showed a significant improvement in rhinitis‐related symptoms in both NAR and AR. In particular, the most significant improvement was observed in symptoms of rhinorrhea and congestion. Furthermore, cryoablation improved the disease‐specific quality of life evaluated using the Rhinoconjunctivitis Quality of Life Questionnaire. The rate of clinical improvement in the total nasal symptom score (total nasal symptom score [TNSS]; >30% reduction from baseline) after cryotherapy was 74%. The change in TNSS score significantly increased over time in NAR patients (p = 0.0041). Therefore, changes in the TNSS score after 12 months of cryotherapy treatment were greater in the NAR group than in the AR group (p = 0.0020), indicating that cryoablation is effective for both types of rhinitis and has better long‐term efficacy in NAR than in AR. Conclusions: Subjective symptom scores related to rhinitis, particularly for rhinorrhea and congestion, decrease after cryoablation of the posterior nasal nerve. Furthermore, the symptom improvement was greater in NAR than AR. Laryngoscope, 134:2502–2512, 2024 [ABSTRACT FROM AUTHOR]

Simple Summary: We compared the diagnostic accuracy of conventional smears and liquid-based preparations for detecting thyroid lesions using fine-needle aspiration cytology. We reviewed 15,861 samples from 17 studies. There was no significant difference between conventional smears and liquid-based preparations in terms of diagnostic accuracy or the proportion of inadequate smears. SurePath outperformed ThinPrep in terms of diagnostic accuracy among the liquid-based preparations. Recommendations for one method over another should take cost, feasibility, and accuracy into account, necessitating additional research. Background: To compare conventional smears (CSs) and liquid-based preparations (LBPs) for diagnosing thyroid malignant or suspicious lesions. Methods: Studies in the PubMed, SCOPUS, Embase, Web of Science, and Cochrane database published up to December 2023. We reviewed 17 studies, including 15,861 samples. Results: The diagnostic odds ratio (DOR) for CS was 23.6674. The area under the summary receiver operating characteristic curve (AUC) was 0.879, with sensitivity, specificity, negative predictive value, and positive predictive value of 0.8266, 0.8668, 0.8969, and 0.7841, respectively. The rate of inadequate specimens was 0.1280. For LBP, the DOR was 25.3587, with an AUC of 0.865. The sensitivity, specificity, negative predictive value, and positive predictive value were 0.8190, 0.8833, 0.8515, and 0.8562. The rate of inadequate specimens was 0.1729. For CS plus LBP, the AUC was 0.813, with a lower DOR of 9.4557 compared to individual methods. Diagnostic accuracy did not significantly differ among CS, LBP, and CS plus LBP. Subgroup analysis was used to compare ThinPrep and SurePath. The DORs were 29.1494 and 19.7734. SurePath had a significantly higher AUC. Conclusions: There was no significant difference in diagnostic accuracy or proportion of inadequate smears between CS and LBP. SurePath demonstrated higher diagnostic accuracy than ThinPrep. Recommendations for fine-needle aspiration cytology should consider cost, feasibility, and accuracy. [ABSTRACT FROM AUTHOR]

Objective: Internal nasal valve dysfunction is a prevalent cause of nasal obstruction. This systematic review, along with a Meta‐analysis, evaluated the efficacy of temperature‐controlled radiofrequency device (RFD) treatment in alleviating nasal obstruction by rectifying nasal valve collapse. Data Sources: A comprehensive review of studies retrieved from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases (up to December 2022) was conducted. Review Methods: We included studies that evaluated the quality of life and nasal obstruction scores before and after RFD treatment. In addition, sham‐controlled studies were analyzed. Results: In total, 451 patients across 8 studies were included in the analysis. Patients who underwent RFD treatment reported a significantly enhanced quality of life 24 months after treatment compared to pretreatment scores. The rates of clinically improved states and positive responses regarding quality of life after treatment were 82% and 91%, respectively. Moreover, the disease‐specific quality of life, as assessed by the Nasal Obstruction Symptom Evaluation score, significantly improved. Conclusion: RFD may help improve nasal obstruction symptoms. Further randomized clinical studies on larger cohorts are essential to substantiate its efficacy in enhancing nasal valve function. [ABSTRACT FROM AUTHOR]

Objectives: To assume the ideal cut-off values and diagnostic performance of two thyroid imaging reporting and data systems published by the Korean Thyroid Association/Korean Society of Thyroid Radiology (Korean TI-RADS) and the American Thyroid Association (ATA TI-RADS). Methods: Eighteen studies with 25,422 patients from PubMed, SCOPUS, Embase, Web of Science, and Cochrane Library databases up to August 2022. True and false positive and negative values with characteristics were extracted. Results: The highest area under the receiver operating characteristic curve (AUC) was 0.893 and 0.887 for Korean and ATA TI-RADS. High suspicion was judged as the best cut-off value with the highest AUC based on optimal sensitivity and specificity. In determining the risk of malignant thyroid nodules, high suspicion in Korean and ATA TI-RADS showed sensitivity as 71.3% and 73.5%, specificity as 7.9% and 86.4%, diagnostic odds ratios as 20.0289 and 20.9076, AUC as 0.893 and 0.887. There was no significant difference when directly comparing the diagnostic accuracy of both TI-RADS. Conclusion: The two risk stratification systems had good diagnostic performance with high AUC and no significant differences. The ideal cut-off can depend on the medical condition or thyroid nodules, because the changes of cut-off point may reciprocally alter sensitivity and specificity. [ABSTRACT FROM AUTHOR]

Objectives: To evaluate the efficacy of topically applied tramadol in peritonsillar area for pain control and induction of perioperative morbidity in children undergoing adenotonsillectomy. Methods: Two authors independently searched the databases (MEDLINE, SCOPUS, and Cochrane databases) up to April 2022 for randomized controlled trials comparing the efficacy of an intraoperative peritonsillar administered tramadol with placebo or other agents only in pediatric patients. The outcomes were postoperative pain scores, time to take the first pain reducing drugs, and postoperative nausea/vomiting. Results: Our analysis was based on 17 trials. Peritonsillar administered tramadol significantly reduced postoperative pain at less than 20 minutes (SMD −1.5852, 95% CI [−2.3900; −0.7804]), 1 hour (SMD −1.5811, 95% CI [−2.3400; −0.8222]), 8 hours (SMD −1.0258, 95% CI [−1.8792; −0.1724]), 16 hours (SMD −0.8397, 95% CI [−1.4266; −0.2529]), and 1 day (SMD −1.0110, 95% CI [−1.5213; −0.5007]) and the time to take the first analgesic drug (SMD 1.6565, 95% CI [0.2838; 3.0293]) compared with the placebo. However, tramadol showed no significant difference on postoperative pain relief effects and the time to take the first analgesic drug compared to the other topical agents (bupivacaine, lidocaine, ketamine, and dexamethasone). Tramadol did not cause significant postoperative nausea and vomiting. Conclusions: This study demonstrated that intraoperatively applied topical tramadol could control postoperative pain and reduce the analgesic uptake compared with a control. However, the efficacy of tramadol in pain control was similar to other agents in pediatric adenotonsillectomy. [ABSTRACT FROM AUTHOR]

Purpose: We evaluated the effects of two doses (186 µg and 372 µg) of exhalation delivery system with fluticasone (EDS-FLU) on chronic rhinosinusitis (CRS) with nasal polyp as a novel sinonasal delivery system.We analyzed 5 studies retrieved from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases up to April 2024, focusing on subjective and objective scores, and adverse and beneficial effects (responder and complete responder rates, improvements in Patient Global Impression of Change [PGIC] scores, and surgical indication rates before and after EDS-FLU use.Over 3 months, EDS-FLU significantly reduced polyp (mean difference [MD] − 1.1605; 95% confidence interval [CI] [− 1.3277; −0.9934], I2 = 61.4%) and 22-item Sinonasal Outcome Test (MD − 20.7561; 95% CI [− 22.3473; −19.1648], I2 = 0.0%) scores compared to baseline. At 1 month, nasal congestion, facial pain, olfactory dysfunction, and rhinorrhea significantly improved compared to baseline. EDS-FLU significantly reduced the surgical indication rate (odds ratio 0.2594; 95% CI [0.1910; 0.3522], I2 = 0.0%) and improved patient satisfaction, with 63.34% of patients reporting significant improvement in PGIC scores after 3 months. However, adverse effects, including epistaxis, headache, nasal congestion, and nasopharyngitis, were reported, with incidence rates ranging from 4.46 to 8.99%. There were no significant differences in beneficial or adverse effects between high and low fluticasone doses, but the high dose was associated with a higher percentage of complete responders.Both doses of EDS-FLU significantly improved subjective and objective outcomes of CRS patients with nasal polyps. However, epistaxis and nasal septal erosive or ulcerative lesions were also considered.Methods: We evaluated the effects of two doses (186 µg and 372 µg) of exhalation delivery system with fluticasone (EDS-FLU) on chronic rhinosinusitis (CRS) with nasal polyp as a novel sinonasal delivery system.We analyzed 5 studies retrieved from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases up to April 2024, focusing on subjective and objective scores, and adverse and beneficial effects (responder and complete responder rates, improvements in Patient Global Impression of Change [PGIC] scores, and surgical indication rates before and after EDS-FLU use.Over 3 months, EDS-FLU significantly reduced polyp (mean difference [MD] − 1.1605; 95% confidence interval [CI] [− 1.3277; −0.9934], I2 = 61.4%) and 22-item Sinonasal Outcome Test (MD − 20.7561; 95% CI [− 22.3473; −19.1648], I2 = 0.0%) scores compared to baseline.

Simple Summary: This meta-analysis determined the optimal cut-off value for differentiating benign and malignant thyroid nodules in two risk stratification systems (ACR and Kwak TI-RADS) and compared their diagnostic performance. Both systems showed good diagnostic performance. TR4 and 4B were estimated as optimal cut-off values for ACR and Kwak TI-RADS, respectively, but the cut-off values can be adjusted in consideration of changes in sensitivity and specificity. (1) Background: To determine the optimal cut-off values of two risk stratification systems to discriminate malignant thyroid nodules and to compare the diagnostic performance; (2) Methods: True and false positive and negative data were collected, and methodological quality was assessed for forty-six studies involving 39,085 patients; (3) Results: The highest area under the receiver operating characteristic (ROC) curve (AUC) of ACR and Kwak TI-RADS were 0.875 and 0.884. Based on the optimal sensitivity and specificity, the highest accuracy values of ROC curves or diagnostic odds ratios (DOR) were taken as the cut-off values for TR4 (moderate suspicious) and 4B. The sensitivity, specificity, DOR, and AUC by ACR (TR4) and Kwak TI-RADS (4B) for malignancy risk stratification of thyroid nodules were 94.3% and 96.4%; 52.2% and 53.7%; 17.5185 and 31.8051; 0.786 and 0.884, respectively. There were no significant differences in diagnostic accuracy in any of the direction comparisons of the two systems; (4) Conclusions: ACR and Kwak TI-RADS had good diagnostic performances (AUCs > 85%). Although we determined the best cut-off values in individual risk stratification systems based on statistical assessment, clinicians can adjust the optimal cut-off value according to the clinical purpose of the ultrasonography because raising or lowering cut-points leads to reciprocal changes in sensitivity and specificity.

Frontal Mucocele grows gradually and unnoticed as a benign lesion but, as the frontal mucocele expands to and compresses surrounding organs like brain, orbit, etc., it can cause diverse symptoms and signs. Although the surgical approaches of mucocele include open, endoscopic and combined approach, endoscopic marsupialization has been commonly used because endoscopic marsupialization was reported with high success rates, low complication rates and better operative vision. However, recently we experienced rare complication of endoscopic marsupialization of huge frontal mucocele, large amount of intracerebral hemorrhage, immediately after successful surgery and report this rare case with short review.

Objective: To assess the diagnostic utility of various radiologic criteria such as the lateral margin or dislocation of the retromandibular vein (RMV), Utrecht line, facial nerve line, Conn's arc, lines passing from the lateral margin of the masseter muscle to the facial nerve trunk or RMV, minimum distance from the fascia to the tumor (MDFT), and direct tracing of the intraparotid facial nerve (DT) for differentiating a parotid deep lobe tumor from a superficial lobe tumor. Methods: Twenty-one studies with 2225 participants from PubMed, Embase, Web of Science, Cochrane Library, SCOPUS, and Google Scholar up to March 2022 were analyzed. Sensitivity, specificity, and negative and positive predictive values of the methods were extracted. Results: The diagnostic odds ratio (DOR) of radiologic criteria compared to surgical findings was 18.9109. The area under the summary receiver operating characteristic curve was 0.879. The sensitivity and specificity were 0.6663 and 0.9190. MDFT (DOR 61.2917) and DT (DOR 91.9883) showed superior results as diagnostic landmarks. For tumors crossing the anatomical criteria line, strict way (any tumor crossing the line) could help differentiate a deep lobe tumor more accurately than conventional way (> 50% of the tumor volume located medial to the line). Conclusion: Various radiologic criteria, especially MDFT and DT, showed good diagnostic accuracy for differentiating a parotid deep lobe tumor. [ABSTRACT FROM AUTHOR]

Background and Objectives: Understanding the anatomical variation in the sphenoid sinus is important to fully expose the sellar floor and clivus. Materials and Methods: The Onodi cell and intersphenoid sinus septation based on preoperative paranasal sinus computed tomography (PNS CT) and the surgical records of 877 patients who underwent the endoscopic endonasal transsphenoidal approach (EETSA) were retrospectively reviewed. Results: An intersphenoid sinus septum (ISS) blocking the clivus was defined as a pseudoclivus. Complete and incomplete pseudoclivuses were found in 2.97% and 10.5% of patients, respectively. Intraoperative and PNS CT ISS findings differed in 17.1% of patients. Misconceptions regarding a ridge or vertical ISS and confusion between an incomplete pseudoclivus and a vertical ISS were common. Conclusions: Because intraoperative and PNS CT findings may differ, anatomical variation in the paraclival area should be evaluated carefully. A pseudoclivus mimicking the clivus is important to attain a fully exposed EETSA surgical view. [ABSTRACT FROM AUTHOR]

Simple Summary: This systemic review and meta-analysis compared and analyzed the safety and effectiveness of transoral robotic thyroidectomy on the thyroid tumor with other thyroid approaches. Transoral robotic thyroidectomy showed similar results to other robotic-assisted thyroid surgeries. Compared to a conventional open thyroidectomy, transoral robotic thyroidectomy had longer operational times and hospitalization days, and worse postoperative pain, but a higher cosmetic satiation score. However, more randomized controlled studies need to be included and analyzed. Background: To assess the safety and effectiveness of transoral robotic thyroidectomy (TORT) in thyroid tumor. Methods: PubMed, Embase, Web of Science, SCOPUS, Cochrane database, and Google Scholar up to June 2022. Studies comparing outcomes and complications between TORT and control groups (robotic bilateral axillo-breast, trans-axillary, postauricular approach, conventional open thyroidectomy (OT), and transoral endoscopic approach) were analyzed. Results: Ten studies of 1420 individuals. The operative time (SMD 1.15, 95%CI [0.48; 1.89]) was significantly longer and the number of retrieved lymph nodes (LNs) (SMD −0.27, 95%CI [−0.39; −0.16]) was fewer in TORT than in the control group. The postoperative cosmetic satisfaction score (SMD 0.60, 95%CI [0.28; 0.92]) was statistically higher in TORT than in the control group. In subgroup analysis, there was no significant difference between robotic surgeries. However, TORT had significantly longer operative times (SMD 2.08, 95%CI [0.95; 3.20]) and fewer retrieved LNs (SMD −0.32, 95%CI [−0.46; −0.17]) than OT. TORT satisfied significantly more patients in cosmetic view. However, it increased hospitalization days and postoperative pain on the operation day and first day compared to OT. Conclusions: TORT is not inferior to other robotic-assisted approaches. Its operation time and hospitalization days are longer and postoperative pain is greater than OT, although its cosmetic satisfaction is high. [ABSTRACT FROM AUTHOR]

Objective: We explored the clinical significances of the relationships among sphenoid sinus aeration, intersphenoid sinus septum (ISS), and internal carotid artery (ICA). Methods: We retrospectively reviewed the preoperative paranasal sinus computed tomography scans and the medical charts of 490 patients who were treated by the endoscopic endonasal transsphenoidal approach. We analyzed sphenoid sinus pneumatization, number of ISS, and positional relationships between the ICA and ISS (including ICA prominence and the thickness of surrounding bone). Results: ISS were often present in the ICAs of patients with presellar pneumatization (36.2%; p = 0.042). Sphenoid sinus pneumatization status significantly differed according to number of ISS (p < 0.001), ICA prominence (p < 0.001), ISS insertion into the ICA (p = 0.042), and distance from ISS to ICA (p = 0.004). When sphenoid sinus aeration was poor, the ICA was not prominent, and the ISS were attached to or lay close to the paraclival ICA. Conclusions: Patients with presellar pneumatization exhibited less prominent ICAs, and more ISS attached to or near the paraclival ICA, than did other patients. Therefore, particular caution is required when using the endoscopic endonasal transsphenoidal approach to treat patients with poor sphenoid sinus aeration. [ABSTRACT FROM AUTHOR]

Summary This study compared the effects of sleeping in the supine position and rapid eye movement sleep on the severity of obstructive sleep apnea, and investigated the effect of sleep stage on position‐dependent obstructive sleep apnea, and of sleep position on rapid eye movement‐dependent obstructive sleep apnea. We analysed epoch‐labelled polysomnographic readouts of 3843 patients, and calculated the apnea–hypopnea index for each sleep position and sleep stage. Subgroup analyses were performed to evaluate whether the proportion of position‐dependent obstructive sleep apnea patients changed during rapid eye movement and non‐rapid eye movement sleep, and whether that of rapid eye movement‐dependent obstructive sleep apnea patients changed during supine/lateral sleep. The apnea–hypopnea index was highest in the rapid eye movement‐supine position (50.7 ± 22.6 events per hr), followed by non‐rapid eye movement‐supine, rapid eye movement‐lateral and non‐rapid eye movement‐lateral (39.2 ± 25.3, 22.9 ± 24.4, 15.9 ± 21.9 events per hr, respectively; p < 0.001). Patients with position‐dependent obstructive sleep apnea had a higher ratio of rapid eye movement sleep, and those with rapid eye movement‐dependent obstructive sleep apnea had a higher ratio of sleep time in the supine position (p < 0.001). During rapid eye movement sleep, position‐dependent obstructive sleep apnea was not observed in 21.1% of patients who otherwise had position‐dependent obstructive sleep apnea. In the lateral position, 36.9% of patients with rapid eye movement‐dependent obstructive sleep apnea did not retain rapid eye movement dependency. Although sleeping in the supine position and rapid eye movement sleep were both associated with more frequent respiratory events, this was the first study to demonstrate that the former had a stronger correlation with obstructive sleep apnea severity. Position dependency in patients with obstructive sleep apnea decreased during rapid eye movement sleep, and worsening of rapid eye movement dependency was alleviated in the lateral position, suggesting potential for personalized obstructive sleep apnea management.

Importance: The newly emerged coronavirus disease 19 (COVID-19), is threatening the world. Olfactory or gustatory dysfunction is reported as one of the symptoms worldwide. As reported so far, different clinical features have been reported according to outbreak sites and gender; most of the patients, who complained of anosmia or hyposmia, were Europeans. We had a fast review for novel articles about COVID-19 infection and olfactory function.Observations: Rapid reviews for COVID-19 or other viral infection and olfactory and/or gustatory dysfunctions were done in this review. Up to date, a lot of reports have shown that olfactory dysfunction is related to viral infections but no exact mechanism, clinical course, and definite treatment have been discovered, which is also same in COVID-19. In general, intranasal steroid (INS) and oral steroid for short time help improve the recovery of the olfactory function in case of olfactory dysfunction after virus infection. Considering severe respiratory complications and immunocompromised state of COVID-19, the use of steroid should be limited and cautious because we do not have enough data to support the usage of steroid to treat olfactory dysfunction in the clinical course of COVID-19.Conclusions and Relevance: In the days of pandemic COVID-19, we should keep in mind that olfactory dysfunctions, even without other upper respiratory infection or otolaryngologic symptoms, might be the early signs of COVID-19.

Objective: To describe the clinical features of invagination of the sphenoid sinus mucosa (ISM) and compare them with other similar cases using a visual analog scale (VAS) to assess the various nasal symptoms and to discuss its clinical significance and means of prevention. Study Design: Retrospective chart review at a tertiary referral center. Methods: Between 2010 and 2015, 8 patients who had undergone EETSA surgery displayed postoperative ISM. The comparison group consisted of 147 patients who underwent the same surgical procedures and were diagnosed with the same diseases. Pre- or postoperative paranasal sinus computed tomography (PNS CT) and VAS were performed and subsequently analyzed. Results: The clinical features of ISM of the sphenoid sinus showed sellar floor invagination and regenerated inverted ingrowing sphenoid mucosa on endoscopic imaging. PNS CT also showed a bony defect and invaginated air densities at the sellar turcica. Pre- and postoperative VAS scores revealed that the ISM group had much less of an improvement in headaches after surgery than that of the comparison group (p = 0.049). Conclusion: ISM may occur because of a change in pressure, sphenoid mucosal status, or arachnoid membrane status. Moreover, ISM is related to improvements in headaches. Therefore, EETSA patients should avoid activities that cause rapid pressure changes during the healing process. In addition, sellar reconstruction that is resistant to physical pressure changes should be mandated despite the absence of an intraoperative CSF leak. [ABSTRACT FROM AUTHOR]
