Abstract	Introduction: Maxillomandibular advancement (MMA) remains an effective procedure for the management of obstructive sleep apnea (OSA). Maxillary advancement may lead to anatomical changes that impair paranasal sinus drainage, leading to chronic sinus inflammation. The aim of this study was to describe the clinical features and outcomes of patients suffering from chronic rhinosinusitis (CRS) following MMA. Methods: This is a retrospective case series study. Our study included subjects diagnosed with CRS following MMA from January 1992 to October 2018 at Stanford Hospital. We screened 730 patients undergoing MMA and identified a total of 57 with CRS after MMA. A descriptive analysis was performed using clinical data including patient demographics, comorbidities, prior surgical history, physical exam manifestations, CT findings, and quality of life outcomes (SNOT-22). Results: Out of 730 patients undergoing MMA, 57(7.8%) were found to have CRS after orthognathic surgery. Presenting symptoms included facial pain (92.5%), nasal drainage (75%), nasal obstruction (67.5%), and hyposmia (20%). Endoscopic examination revealed recirculation (30.5%), purulent discharge (27.7%), polypoid changes (22.2%), and scarring (13.8%). Preoperative CT prior to undergoing endoscopic sinus surgery (ESS) demonstrated mucosal thickening in maxillary (64.2%), anterior ethmoid (39.2%), frontal (14.2%), posterior ethmoid (10.7%), sphenoid sinus (14.2%), and ostiomeatal complex (55.3%). Average Lund-Mackay score was 5.5(±3.8). Additional CT findings included secondary ostium in the inferior meatus (42.8%). Forty patients (70.1%) underwent ESS at a mean of 4.6 years after MMA. Patients undergoing ESS experienced significant improvement in SNOT-22 scores at 12-months post-surgery ( Conclusion: Patients undergoing maxillary advancement surgery are at risk of developing CRS postoperatively and should be advised of the risk of CRS associated with this procedure. Surgical treatment can be an option for medically refractory CRS related to MMA surgery.

Abstract	Objective: This study aimed to evaluate the impact of the COVID-19 pandemic on the otolaryngology residency training program in Vajira Hospital, Navamindradhiraj University. Methods: Conducted from October 2021 to January 2022, this cross-sectional survey included all residents, residents who graduated in 2021, and the attending staff. One form was sent to both resident groups for self-assessment and another form to the attending staff for resident assessment. The survey questions were about attitude toward COVID-19 service, knowledge, outpatient department service, surgical skills, and burnout assessment using the Maslach Burnout Inventory. Results: This study included 17 residents and 9 attending staff members. COVID-19 indeed had affected the clinical and surgical training. Regarding the attitude toward COVID-19 services, the residents were moderately satisfied. They were concerned about work suspension resulting from infection and also death from COVID-19. N95 masks and other protective gears were scarce. Compared with those during the prepandemic era, residents had fewer academic activities, and they preferred hybrid teaching. The inpatient department, outpatient department, and surgical training opportunities, as well as elective and urgent surgeries, were also reduced. The attending staff considered 1-year extension of the training program, but the residents disapproved. The residents became less confident both in outpatient department service and surgical skill, and they felt emotional exhaustion, depersonalization, and decreased sense of personal accomplishment. Conclusion: COVID-19 pandemic had significant impact on otolaryngology residency training programs. It did not only affect burnout among residents but also caused a perception of skill and knowledge reduction.

Abstract	Importance: Postviral olfactory loss is a common cause of olfactory impairment, affecting both quality of life as well as overall patient mortality. It is currently unclear why some patients are able to recover fully after a loss while others experience permanent deficit. There is a lack of research on the possible association between postviral olfactory loss and other cranial neuropathies. Objective: To evaluate the incidence of other cranial nerve deficits in patients with postviral olfactory loss and determine if there is an association with neurologic injury in this group. This study also sought to determine if other known risk factors were associated with postviral olfactory loss. Design, setting, and participants: A case-control study was conducted at a tertiary care rhinology clinic from January 2015 to January 2018 to review the incidence of cranial neuropathies in 2 groups of patients, those with postviral olfactory loss and those with chronic rhinosinusitis without olfactory loss used as a control group. Exposures: The Stanford Translational Research Integrated Database Environment (STRIDE) system was used for patient identification and data extraction. Patients with a history of olfactory loss or chronic rhinosinusitis as well as incidence of cranial neuropathies were identified by using International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) codes. Main outcomes and measures: This study reviewed incidence of postviral or idiopathic cranial neuropathies in both patient groups, while also evaluating for any difference in demographic characteristics, comorbidities, or other patient-related factors. Results: There were 91 patients in the postviral olfactory loss group and 100 patients in the control group, which were age and sex matched as closely as possible. Of the 91 patients with postviral olfactory loss, mean (SD) age was 56.8 (15.3), and 58 (64%) were women; for the control group, the mean (SD) age was 57.5 (15.6) years, and 63 (63%) were women. Racial breakdown was similar across cases and controls, with white individuals making up 59% to 65%; Asian individuals, 20% to 24%; black individuals, approximately 3%; Hispanic individuals, approximately 1%; and the remaining patients being of other race/ethnicity. The incidence of other cranial neuropathies in the postviral olfactory loss group was 11% compared with 2% within the control group (odds ratio, 6.1; 95% CI, 1.3-28.4). The study also found 2 cases of multiple cranial neuropathies within a single patient within the olfactory group. Family history of neurologic disease was associated with more than 2-fold greater odds of cranial nerve deficit (odds ratio, 3.05; 95% CI, 0.59-15.68). Conclusions and relevance: Postviral olfactory loss appears to be associated with a higher incidence of other cranial neuropathies. It is possible that there is an inherent vulnerability to nerve damage or decreased ability for nerve recovery in patients who experience this disease process.

Abstract	Background: Venous thromboembolism (VTE) is a potentially fatal perioperative complication. The objective of this study was to assess the rate and risk factors for VTE in endoscopic skull base surgery (ESBS). Methods: This was a retrospective review of adults undergoing ESBS at a tertiary academic center. Incidence of VTE in the 30-day postoperative period was recorded. Logistic regression analyses identified factors associated with VTE. Results: A total of 1122 ESBS cases performed at Stanford University School of Medicine between 2009 and 2019 were studied. Almost all cases (96.1%) did not employ perioperative VTE chemoprophylaxis. The overall incidence of VTE was 2.3% (26/1122). Malignant pathologies had a higher rate of VTE compared with nonmalignant pathologies (4.5% vs 2.0%, odds ratio [OR] 2.85, 95% confidence interval [CI] 1.22-6.66). Factors associated with an increased risk of VTE included a Caprini score greater than 5 (OR 1.53, 95% CI 1.28-1.83); multiple preoperative endocrinopathies such as the syndrome of inappropriate antidiuretic hormone secretion (SIADH) (OR 22.48, 95% CI 3.93-128.70), adrenal insufficiency (OR 5.24, 95% CI 1.82-15.03), hypercortisolism (OR 4.46, 95% CI 1.47-13.56), and hypothyroidism (OR 3.69, 95% CI 1.66-8.20); each 10-hour increment of lumbar drain duration (OR 1.16, 95% CI 1.08-1.25); and each 10-hour increment for duration of hospitalization (OR 1.05, 95% CI 1.03-1.06). Conclusions: The incidence of VTE following ESBS is relatively low at 2.3%. Factors with a higher association of VTE include malignancy, preoperative endocrinopathies, higher Caprini score, prolonged lumbar drain duration, and prolonged hospitalization. Larger, multi-institutional studies are needed to validate these findings and to better refine clinical decision-making regarding perioperative VTE prophylaxis.

Abstract	Background: The objective of this study is to characterize changes in hemodynamics, pain, and anxiety during office-based endoscopic sinus procedures performed under local anesthesia. Methods: We conducted a prospective study of adults undergoing in-office endoscopic sinus procedures under local anesthesia. Patients with American Society of Anesthesiologists (ASA) Physical Status Classification System class 1 or 2 were included. Anesthesia was administered by topical 4% lidocaine/oxymetazoline and submucosal injection of 1% lidocaine/1:200,000 epinephrine. Vital signs and pain were measured at baseline, postinjection, and 5-minute intervals throughout the procedure. Anxiety levels were scored using the State-Trait Anxiety Inventory (STAI). Univariate and multivariate regression analyses were performed to identify factors significantly associated with changes in each hemodynamic metric. Results: Twenty-five patients were studied. This cohort was 52% male, mean age of 57.8 ± 14.4 years, and Charlson Comorbidity Index (CCI) median of 2. Mean procedure duration was 25.0 ± 10.3 minutes. Mean maximal increase in systolic blood pressure (SBP) was 24.6 ± 17.8 mmHg from baseline. Mean maximal heart rate increase was 22.8 ± 10.8 beats per minute (bpm) from baseline. In multivariate regression analysis, when accounting for patient age, cardiac comorbidity, CCI, and ASA, older age was significantly associated with an increase of >20 mmHg in SBP (p = 0.043). Mean pain score during procedures was 1.5 ± 1.3 with a mean maximum of 4.0 ± 2.6. STAI anxiety scores did not change significantly from preprocedure to postprocedure (32.8 ± 11.6 to 31.0 ± 12.6, p = 0.46). No medical complications occurred. Conclusion: Although patients appear to tolerate office procedures well, providers should recognize the potential for significant fluctuations in blood pressure during the procedure, especially in older patients.

Abstract	Background: The literature regarding clinical olfaction, olfactory loss, and olfactory dysfunction has expanded rapidly over the past two decades, with an exponential rise in the past year. There is substantial variability in the quality of this literature and a need to consolidate and critically review the evidence. It is with that aim that we have gathered experts from around the world to produce this International Consensus on Allergy and Rhinology: Olfaction (ICAR:O). Methods: Using previously described methodology, specific topics were developed relating to olfaction. Each topic was assigned a literature review, evidence-based review, or evidence-based review with recommendations format as dictated by available evidence and scope within the ICAR:O document. Following iterative reviews of each topic, the ICAR:O document was integrated and reviewed by all authors for final consensus. Results: The ICAR:O document reviews nearly 100 separate topics within the realm of olfaction, including diagnosis, epidemiology, disease burden, diagnosis, testing, etiology, treatment, and associated pathologies. Conclusion: This critical review of the existing clinical olfaction literature provides much needed insight and clarity into the evaluation, diagnosis, and treatment of patients with olfactory dysfunction, while also clearly delineating gaps in our knowledge and evidence base that we should investigate further.
