Trends of Odontogenic Sinusitis Incidence During the COVID-19 Pandemic.

OBJECTIVES: The COVID-19 pandemic affected the epidemiology of several diseases. This study aims to compare the incidence of surgically treated odontogenic sinusitis (ODS) before and during the COVID-19 pandemic and identify unique features. METHODS: A retrospective chart review of patients who underwent at least maxillary antrostomy at a tertiary referral center was performed. The patients were divided into two cohorts: "pre-COVID" (March 2018 to February 2020) and "COVID" (March 2020 to February 2022). Data on demographics, comorbidities, and treatment interventions were collected and analyzed. RESULTS: Of the 734 patients who underwent maxillary antrostomy, 370 (50.4%) were operated on during the COVID period, with a mean age of 53.1 ± 15.7 years. ODS was found as the etiology of 22 (6%) and 45 (12.2%) of the pre-COVID and COVID cases, respectively (p = 0.006). Although no difference was found in the incidence of diabetes (p = 0.9) or obesity (p = 0.7) between groups, a trend toward higher incidence of immunosuppression was found in the pre-COVID patients (18.2% vs. 0%, p = 0.06). A higher incidence of sphenoid sinus involvement (31.8% vs. 8.9%, p < 0.05) was identified in the pre-COVID group; however, no differences in ethmoid (86.4% vs. 86.7%, p = 0.999) or frontal sinus involvement (54.5% vs. 37.8%, p = 0.3) were found between the groups. CONCLUSION: There was an increase in the incidence of ODS during the first 2 years of the COVID-19 pandemic compared to the 2 years prior. Similar clinical characteristics were found in both groups. Future studies focusing on specific etiologies to explain ODS preponderance may help determine optimal treatment and prevention strategies. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:1597-1602, 2024.

Quality of life after radio frequency ablation turbinate reduction (RFATR) among patients with rhinitis medicamentosa & withdrawal from decongestant topical spray abuse.

OBJECTIVE: Radiofrequency ablation (RFA) reliefs nasal obstruction and improves quality of life (QoL) in patients suffering from inferior turbinate hypertrophy (ITH). A substantial benefit was noted among patients suffering from Rhinitis Medicamentosa (RM), enabling ending decongestant spray abuse. Our aim was to establish the benefit from RFA with respect to QoL in patients suffering from ITH, due to the presence of RM. STUDY DESIGN: Prospective cohort study. METHODS: Prospective Cohort study, including patients suffering from ITH undergoing RFA between 9.2017 and 9.2019 in Tel Aviv Medical Center. The cohort was divided to RM and non-RM (including allergic, non-allergic) patients. The differences between the groups were compared before and after RFA, and included patients' complaints, clinical findings and QoL questionnaires (SNOT-22 & NOSE). In the RM group, the ability to wean from decongestants was also described. RESULTS: Our data demonstrated subjective QoL improvement following RFA (88.9 %, N = 90). All RM patients withdrawaled from nasal decongestant spray. NOSE questionnaire demonstrated a significant improvement in QoL after RFA in the RM group (PV = 0.025). SNOT-22 did not demonstrate significant difference in QoL between RM and the reference group (PV = 0.1). Rates of MCID>8.3 were high, without significant difference between the groups (PV = 0.2). CONCLUSION: RFA demonstrated effectiveness in achieving of withdrawal from decongestant spray in RM patients and may be a possible definitive treatment option for this group. The nasal obstruction component in SNOT-22 questionnaire & NOSE questionnaire showed improved QoL in comparison to controls. High QoL after RFA was established in our entire cohort.

Lateral Neck Dissection for Well-Differentiated Thyroid Carcinoma: Is Prophylactic Level V Neck Dissection Necessary? A Retrospective Cohort Study.

OBJECTIVE: The presence of clinically detectable papillary thyroid carcinoma (PTC) metastases in the lateral neck is an indication for neck dissection (ND) and thyroidectomy. Although there is a consensus regarding the importance of therapeutic selective ND of involved levels II to IV in patients with clinically evident locoregional metastatic disease, the prognostic benefit of level V prophylactic ND remains debatable. METHODS: All patients who underwent thyroidectomy with ND for metastatic PTC between 2006 and 2019 were included in a single-institution retrospective study. Preoperative characteristics at initial presentation, imaging workup, intraoperative findings, and the final histopathological reports were retrieved from the institutional database. RESULTS: A total of 189 patients with locally advanced PTC were identified, of whom 22 (11.6%) patients underwent therapeutic selective ND at levels II to IV together with level V dissection due to clinical involvement. Comparison of the patients who were operated on level V to those who were not revealed no significant difference. The disease recurrence rate was 20.1% throughout an average follow-up of 5.1±3.1 years. No significant differences in recurrence rate were found between patients who underwent and those who did not undergo level V ND (22.7% vs 19.8%, P = .648). No recurrence at resected level V was detected during follow-up, while recurrence at level V was found in 4 (2.1%) patients who did not undergo level V dissection. Evidence of macroscopic and microscopic extrathyroidal extension was significant predictors of disease recurrence risk. CONCLUSION: There were no significant associations between level V dissection and risk for recurrence. Recurrence at level V was rare (4/189 patients, 2.1%). Our study's findings suggest a low prophylactic benefit of an elective level V ND. Elective level V ND should not be done routinely when lateral ND is indicated but should rather be considered after careful evaluation in high-risk patients.

A Prospective Evaluation of Quality of Life in Patients Undergoing Extended Endoscopic Endonasal Surgery for Benign Pituitary Gland Lesion.

Introduction Endoscopic endonasal surgery (EES) has become the preferred approach for pituitary tumor resection. Nevertheless, research on quality of life related to pituitary adenoma surgery is scarce. Objective The aim of the study is to evaluate short-term quality of life in patients after endoscopic endonasal resection of pituitary tumors and to find predictors for poor quality of life (QOL) outcome. Materials and Methods A prospective cohort study was conducted, including all patients who underwent EES for pituitary tumors in a tertiary medical referral center. Recruited patients completed the Anterior Skull Base Disease-Specific QOL (ASBS-Q) questionnaire and the Sinonasal Outcome Test 22 (SNOT-22) questionnaire before surgery, 2 and 4 to 6 months after surgery. Demographic and clinical data was collected. Results Our study included 49 patients. The overall ASBS-Q scores significantly improved 4 to 6 months after surgery (4.46 vs. 4.2, p < 0.05). We found a significant improvement in QOL related to emotional state 2 months post surgery (4.41 vs. 3.87, p < 0.05), which became borderline significant 4 to 6 months post surgery. There was a significant improvement in pain (4.5 vs. 4.08, p < 0.05) and vitality (4.43 vs. 4.16, p < 0.05) domains 4 to 6 months post surgery. SNOT-22 scores did not change significantly postoperatively. Factors such as secreting and non-secreting tumors, tumor size, intraoperative cerebrospinal fluid leak, gross tumor resection, endocrine remission, and the use of nasoseptal flap reconstruction did not have a significant effect on QOL. Conclusion We found that patients after EES reported improved QOL 4 to 6 months post surgery. Specific improvement was noted in the QOL related to pain and vitality.

Histopathological Characteristics of N1b Papillary Thyroid Carcinoma are Associated with Risk of Recurrence.

BACKGROUND: The presence of cervical lymph node (LN) metastasis at the initial presentation of papillary thyroid carcinoma (PTC) constitutes an independent risk factor for disease recurrence, increases the risk for mortality, and impacts overall outcome. The 2016 American Joint Committee on Cancer raised the age cutoff for PTC staging from 45 to 55 years for better prediction of overall survival. Age > 55 years is considered a significant risk factor for a more aggressive and advanced disease with worse outcomes. We identified histopathological factors for disease recurrence in PTC patients younger and older than 55 years of age. METHODS: Data on all patients who underwent thyroid surgery due to PTC between 2006 and 2018 in the Tel Aviv Sourasky Medical Center were retrieved for this retrospective cohort study. Patients with lymph node (LN) metastases were further investigated for preoperative presentation, pathological characteristics, and recurrence. A multivariate analysis was used to detect predictors for recurrence and patient outcome for each age-group. RESULTS: Twenty-two of the 183 patients (12%) with PTC who met the inclusion criteria and had sufficient follow-up period sustained recurrence. The predictors of recurrence varied between the two age-groups. The size of thyroid lesions (p = 0.003) was identified as a risk factor in the older group, while the number of metastatic cervical LNs (p = 0.001) and the ratio of metastatic-to-total dissected cervical LNs (p = 0.027) were the main predictors of recurrence for the younger group. CONCLUSION: The histopathological factors predictive for disease recurrence differed among PTC patients younger and older than 55 years of age.

The effect of septal deviation on postoperative quality of life in patients undergoing radiofrequency-assisted turbinate reduction.

Objectives: Inferior turbinate hypertrophy (ITH) and nasal septum deviation are leading causes of chronic nasal obstruction. Radiofrequency ablation (RFA) of hypertrophic inferior turbinates is effective for improving quality of life (QOL). We aim to assess QOL among patients with nasal obstruction associated with ITH and major deviated nasal septum. Methods: A prospective cohort study comparing the difference in improved QOL among patients with and without septal deviation following RFA treatment between March 2016 and June 2019. The patients formed two groups according to their grade of septal deviation. Patients participating filled in QOL questionnaires (Sino-Nasal Outcome Test-22 [SNOT-22] and Nasal Obstruction Symptom Evaluation [NOSE]) Pre- and 2 months postprocedure. Results: All patients demonstrated QOL improvement with no significant difference between those with and those without any degree of deviated septum, as demonstrated by their responses to the SNOT-22 questionnaire (p = .29), the NOSE questionnaire (p = .93), and the degree of nasal obstruction (question 22 in the SNOT-22 questionnaire) (p = .14). Conclusion: We conclude that septal deviation to certain degree does not preclude treatment of ITH with RFA nor does it negatively affect subjective improvement of the patient's QOL. Both those with and those without septal deviation will benefit similarly with regards to subjective QOL improvement.

The incidence of postoperative re-stratification for recurrence in well-differentiated thyroid cancer-a retrospective cohort study.

BACKGROUND: After diagnosing well-differentiated thyroid cancer (WDTC), assessment of the risk for disease-specific recurrence is essential for deciding between hemi-thyroidectomy (HT) and total thyroidectomy (TT). The American Thyroid Association (ATA) 2015 guidelines suggest that patients with 1-4 cm WDTC without suspicious features may be suitable for HT. Patients' preoperatively determined risk levels are re-stratified according to surgical and final histopathological findings. The incidence and clinical implications of high-risk features discovered postoperatively in patients with preoperatively determined low-risk WDTC are yet to be better defined. METHODS: Thyroidectomies performed in the Tel-Aviv Sourasky Medical Center (TASMC) [2006-2018] were included. Patients with 1-4 cm WDTC without evidence of positive cervical lymph nodes, invasion to adjacent structures, or high-risk cytology were considered at low risk for disease-specific recurrence-suitable for lobectomy. Patients were stratified according to their risk for disease-specific recurrence, pre- and postoperatively, and the rate of completion thyroidectomy was determined. RESULTS: In total, 301 (21%) patients were preoperatively stratified as low risk. Forty-six of them (15%) were re-stratified postoperatively as intermediate-to-high-risk. There were no significant differences in the characteristics of the patients who maintained their original stratification to patients who were upscaled to a higher risk level postoperatively. CONCLUSIONS: We report a 15% rate of postoperative risk escalation of patients who required completion thyroidectomy according to current ATA guidelines. In our opinion, this rate of postoperative WDTC upscaling of risk requiring more radical surgery than originally planned, is acceptable. Meticulous preoperative personalized evaluation by an experienced multidisciplinary dedicated team is essential.

Skull Base Reconstruction with Multilayered Fascia Lata: A Single-Center 17 Years Experience.

Objective Reconstruction after open surgery of anterior skull base lesions is challenging. The fascia lata graft is our workhorse for achieving dural sealing and preventing cerebrospinal fluid leak and meningitis. This study seeks to analyze the donor and recipient site complication rates after fascia lata reconstruction. Methods This is a retrospective review of all open anterior skull base operations in which a double-layer fascia lata graft was used for the reconstruction of the defect from 2000 to 2016 at the Tel-Aviv Sourasky Medical Center, a tertiary referral center in Israel. Results Of the 369 patients operated for skull base lesions, 119 underwent open anterior skull base surgery and were reconstructed with a fascia lata graft. The patients' mean age was 47.1 years, and 68 (57.1%) were males. The overall postoperative early and late donor site complication rates were 6.7% ( n = 8) and 5.9% ( n = 7), respectively. Multivariate analysis found minor comorbidities and persistent/recurrent disease as being predictors for early-term complications. The overall postoperative early central nervous system (CNS) complication rate was 21.8% ( n = 26), while 12.6% ( n = 15) of the patients had late postoperative CNS complications. Conclusion Reconstruction of open anterior skull base lesions with fascia lata grafting is a safe procedure with acceptable complication and donor site morbidity rates.

Observation Rather than Surgery for Benign Parotid Tumors: Why, When, and How.

Surgery is the preferred treatment of benign parotid lesions, but it carries a risk of complications. Therefore, the approach toward the surgery of these lesions should seek to avoid complications. There are no guidelines or recommendations for when not to operate. Integration of comorbidities and other factors shift the scales from surgery toward observation in a small subset of patients presenting with parotid tumors. When observation is chosen, the patient should be followed frequently and cautiously, and the surgeon should be prepared to change strategy to surgical excision if in doubt.

The Role of Imaging in the Preoperative Assessment of Patients with Nasal Obstruction and Septal Deviation-A Retrospective Cohort Study.

Introduction Isolated nasal obstruction (INO) is a common complaint of multiple etiology. The preoperative evaluation of patients presenting with nasal obstruction and deviated nasal septum (DNS) does not typically include imaging. The benefits of performing computed tomography (CT) in the preoperative setting are inconclusive. Objective Assessing the contribution of preoperative CT to the surgical treatment of non-sinusitis patients presenting with INO and DNS. Methods A retrospective cohort study on patients referred to surgery for nasal obstruction due to DNS or turbinate hypertrophy between 2006 and 2015. Data was retrieved from patients' medical charts. The CT scans and clinical data were reassessed by a second surgeon blinded to the patients' clinical course. Results Seventy of the 843 patients (8.06%) who underwent endoscopic sinonasal procedures during the study period had presented with INO and met the inclusion criteria. Thirty-eight (55.88%) of them underwent CT scans during their preoperative assessment. Modification of the initial preoperative planning based on the radiological findings was required in 32 cases (84.2%). When reassessed by a second blinded surgeon, 58% of cases required surgical modification rather than classical submucosal resection of nasal septum and turbinate reduction ( P = 0.048). Conclusion Computed tomography was found beneficial in the preoperative planning for patients with INO. The original surgical plan based upon physical examination findings was modified based on radiological findings in 84.2% of the patients.

Averting Delayed Complications of Open Anterior Skull Base Surgery.

Objective Despite its technical feasibility, anterior skull base surgery still carries the risk of severe postoperative complications, morbidity, and mortality. The reported rate of complications has diminished over the past two decades, but they continue to pose various challenges. This study aims to report late complications in a relatively large series of patients who underwent open anterior skull base surgery, and to propose methods for averting such complications. Methods Retrospective chart review of all patients who underwent anterior open skull base surgery between 2000 and 2016 in a university-affiliated tertiary referral cancer center. Results There were 301 operations, of which 198 (65.8%) were for benign disease and 103 (34.2%) were for malignant tumors. The male-to-female ratio was 1.4:1, and the mean age was 44.8 years. Delayed complications occurred in 85 patients (28.2%): 31 (10.3%) involved wounds, 18 (13.9%) involved the central nervous system, and 14 (4.6%) involved the orbit. Multivariate analysis found malignant pathology, intracranial extension, and previous radiochemotherapy as predictors for the development of a delayed complication. The patients who were operated in the later study period (after 2007) had lower rates of all three types of complications compared with the earlier study period. Conclusion Delayed complications following skull base surgery are in decline. This is mainly due to the advancement in imaging studies, surgical techniques, development of sophisticated reconstructive procedures, and the cooperation of multidisciplinary teams. We attribute the reduction in our department to our revised treatment protocol which is presented herein, with emphasis on averting the occurrence of these complications. Level of Evidence The level of evidence is 4.

Psychometric testing of the Skull Base Inventory health-related quality of life questionnaire in a multi-institutional study of patients undergoing open and endoscopic surgery.

PURPOSE: The skull base inventory (SBI) was developed to better assess health-related quality of life (HR-QOL) in patients with anterior and central skull base neoplasms treated by endoscopic and open approaches. The primary objective of this study was to prospectively assess the psychometric properties of the SBI. METHODS: This study is part of a multi-center study of patients undergoing endoscopic and open procedures completed between 2012 and 2018. Participants were eligible if they were over 18 years of age; had benign or malignant anterior, antero-lateral, or central skull base tumors; and required either an open or endoscopic skull base surgical approach. In order to assess the psychometric properties of the SBI, patients completed the instrument at six time points (preoperative, 2 weeks, 3 months, 6 months, 12 months postoperative). Patients also completed the Anterior Skull Base (ASB) questionnaire and the Sinonasal Outcome Test (SNOT-22) to allow comparison to the SBI. RESULTS: One hundred and eighty-seven patients were included across five centers, with 121 having an endoscopic procedure. Internal consistency (Cronbach's alpha = 0.95) and test-retest at 12 months and 12 months plus 2 weeks (intraclass correlation > 0.90) were excellent. Concurrent validity was demonstrated by very strong correlation between total SBI scores and ASB scores (r = 0.810 to 0.869, p < 0.001) and moderate correlation between nasal domain SBI scores and SNOT-22 scores (r = - 0.616 to - 0.738, p < 0.001). Convergent validity was demonstrated by moderate correlation between change in SBI scores and global QOL change (rs = 0.4942, p < 0.001). The minimally important clinical difference (global HR-QOL change of "a little better" or "a little worse") was 6.0. CONCLUSION: The SBI questionnaire is reliable and valid for patients treated by both endoscopic and open approaches and can be used for assessment of HR-QOL in these settings.

Prophylactic central neck dissection has no advantage in patients with metastatic papillary thyroid cancer to the lateral neck.

BACKGROUND: Papillary thyroid cancer (PTC) usually metastasizes via lymphatic channels in a sequential fashion, first to the central compartment, followed by the lateral neck. PTC patients diagnosed with lateral neck disease (N1b) without proof for central involvement traditionally undergo prophylactic central neck dissection (pCND). However, substantial evidence on outcomes to support this approach is lacking. MATERIALS AND METHODS: We conducted a dual center retrospective study to compare the rate of central neck recurrence between N1b PTC patients undergoing pCND and those spared pCND. All patients diagnosed with N1b PTC who underwent total thyroidectomy and lateral neck dissections with or without pCND between January 1998 and December 2015 were included in this study. The rates of central neck recurrences were compared between the groups. RESULTS: The 111 patients who met the inclusion criteria were 44 females (39.6%) and 67 males (60.4%), with a mean age of 50.2 ± 17.7 years, and a mean follow-up of 10.2 ± 5.3 years. Sixty patients (54.1%) underwent a pCND and 51 patients (45.9%) did not (non-pCND). During follow-up, 18 patients (16.2%) had level VI recurrences, 13 in the pCND group and 5 in the non-pCND group. Cox-regression models with propensity scoring did not reveal any inclination or an advantage for performing pCND. CONCLUSION: The present study demonstrated no advantage in performing pCND to prevent central neck recurrence among PTC patients with lateral neck involvement only. These findings question the need for pCND in patients without clinical evidence of central neck disease.

Free flap transfers for head and neck and skull base reconstruction in children and adolescents - Early and late outcomes.

OBJECTIVES: Reconstruction of surgical defects by free tissue transfer following resection of head and neck tumors in children are sparse. This study aims to assess the feasibility and safety of free flap reconstruction following surgical ablation of head and neck and skull base tumors in children based on our experience and the recent literature. METHODS: Data from medical files of all children and adolescents <18 years of age who underwent free flap reconstruction following resection of head and neck and skull base tumors at our tertiary center between 2000 and 2018 were retrospectively reviewed. Data on early and late complications at the primary and donor sites, functional and aesthetic outcome, and tumor control were analyzed. RESULTS: Twenty-four children (mean age 11.3 ± 5.1 years) were enrolled. Early complications occurred in 14 (56%) and late complications occurred in 8 (32%) of the procedures, with surgical intervention required in 4 (16%). Prior chemoradiation, sarcoma, non-reanimation procedures, and the use of rectus abdominis free flaps were associated with higher complication rates. The final functional and cosmetic outcomes, including mastication, deglutition, and speech, were satisfactory in all patients with one exception. CONCLUSIONS: Free flap transfer is a safe and feasible technique for reconstructing head and neck and skull base defects following surgical excision of tumors in children. Early identification and precautionary measures against the effects of potential causes of complications may improve outcome. Larger international cohort studies are warranted.

Total thyroidectomy with therapeutic level II-IV neck dissection for papillary thyroid carcinoma: level VI recurrence patterns.

OBJECTIVE: Lateral and central compartments cervical lymph nodes metastases are common among patients with papillary thyroid carcinoma (PTC). Elective level VI neck dissection during thyroidectomy and lateral neck dissection (LND) for the treatment of PTC with lateral compartment lymph node metastases is controversial because of the uncertain benefit in clinical outcomes and increased risks of surgical morbidity. We aimed to determine the potential benefit of elective level VI neck dissection in patients with cN1 papillary thyroid carcinoma (PTC) by investigating the rate and pattern of locoregional recurrence in PTC patients who underwent total thyroidectomy and therapeutic lateral node dissection (LND; levels II-IV) without elective level VI dissection. METHODS: A retrospective cohort study. Data on demographics, clinical presentation and workup, intraoperative and pathological report, postoperative course, adjuvant therapy, recurrence patterns, and overall survival were retrieved from the medical charts of patients who underwent thyroid surgery in our hospital between January 2006 and December 2017. RESULTS: A total of 1415 thyroidectomies were performed during the study period, of which 802 (56.67%) were for PTC. Of those PTC patients, 228 (28.42%) also underwent LND (levels II-VI) during the same thyroidectomy procedure. Thirty-four (14.91%) of those 228 patients, underwent total thyroidectomy with therapeutic lateral ND II-IV without elective level VI ND. During the follow-up period, five (14.7%) of the latter cohort were diagnosed with recurrence in central neck (level VI) lymph nodes, and four of them (11.7%) were diagnosed with ipsilateral recurrence at level VI. CONCLUSION: Our results revealed 11.7% rate of clinically significant recurrent disease in ipsilateral level VI which, in our opinion, does not justify routine prophylactic level VI ND dissection when the ipsilateral lateral neck is operated for metastases.

Endoscopic posterior cordotomy for treatment of dyspnea due to vocal fold immobility.

INTRODUCTION: Several surgical procedures have been described for the treatment of respiratory distress secondary to vocal fold immobility (VFI), but the contribution of posterior cordotomy (PC) to tracheostomy weaning or prevention has not been studied in depth, particularly in the acute setting. The objective of this study was to show the effectiveness of PC to relieve dyspnea, prevent the need for tracheostomy, and enable decannulation in patients with VFI. METHODS: We conducted a retrospective study and reviewed the medical records of all patients whose dyspnea warranted surgical intervention from January 2013 to January 2018. Data were retrieved on epidemiology, etiology, and duration of VFI, tracheostomy dependence, success in decannulation from tracheostomy or respiratory relief, number of procedures until decannulation, and complications. RESULTS: Twelve suitable patients were identified of whom eleven had bilateral VFI and one had unilateral VFI. Five were tracheostomy-dependent. Ten patients underwent unilateral PC, and two patients underwent bilateral PC. All the patients experienced respiratory relief, eleven after a single PC and one after two PCs. All tracheostomy-dependent patients were decannulated. The mean follow-up after PC was 24.55 months during which none of the patients required a re-tracheostomy and three patients required revision of the PC. There were no surgical complications. Postoperatively, eight patients (67%) experienced a breathy voice and three patients (25%) had dysphagia for fluids. No patient had aspiration pneumonia. CONCLUSIONS: We conclude that PC is an easy, safe, and effective procedure for tracheostomy weaning and respiratory relief in patients with VFI. A revision PC may be indicated in some patients. A breathy voice is to be expected, and a few patients will experience dysphagia to fluids that may be addressed by instructing the patient to use a fluid thickener and take small sips.

Low rates of airway intervention in adult supraglottitis: A case series and meta-analysis.

PURPOSE: Acute supraglottitis (SG) can potentially lead to rapid airway obstruction. The last few decades have witnessed a shift towards a more conservative approach in airway management of adult SG. This study aims to evaluate this watchful approach based on a large case series combined with a high-level meta-analysis of all reports in the English literature. METHODS: Retrospective case series and meta-analysis. The medical records of all adult patients diagnosed as having SG who were hospitalized in a large-volume tertiary referral center between January 2007 and December 2018 were reviewed. A meta-analysis was conducted on all English literature published between 1990 and 2018. RESULTS: A total of 233 patients (median age 49.1 years, 132 males), were admitted due to acute SG during the study period. No airway intervention was required in 228 patients (97.9%). Five patients (2.1%) required preventive intubation, and two of them (0.9%) were later surgically converted to a tracheotomy. Patients who required airway intervention had higher rates of diabetes (P = .001), cardiovascular diseases (P = .036) and other comorbidities (P = .022). There was no mortality. The meta-analysis revealed that the overall intubation rates random effects model was 8.8% [95% confidence interval (CI) 4.6%-14.0%] and that the tracheotomy random effects model was 2.2% (95% CI; 0.5%-4.8%). The overall mortality rate was 0.89%. CONCLUSIONS: This study provides evidence of low rates of surgical airway intervention in patients diagnosed with SG worldwide. A conservative approach in adult SG is safe and should be advocated. LEVEL OF EVIDENCE: 2.

Acute supraglottic laryngitis complicated by vocal fold immobility: prognosis and management.

PURPOSE: Acute supraglottic laryngitis (ASL) is manifested by supraglottic inflammation that has the potential for rapid and fatal airway obstruction. Complete/incomplete vocal fold immobility (VFIm) in the setting of ASL may contribute to airway obstruction. The rate of VFIm complicating ASL is not known, and it is not clear whether its occurrence alters the course and the management of ASL, particularly the need to secure the airway (by endotracheal intubation/tracheostomy). This study seeks to describe the natural history of VFIm associated with ASL (ASLIm) and to determine the added effect of VFIm on ASL severity, management, and the need for intervention to secure the airway. METHODS: This is a retrospective cohort study in a tertiary referral center. The medical records of all patients hospitalized due to ASL between January 2007 and December 2016 were reviewed. RESULTS: Of the 214 patients admitted due to ASL, VFIm was identified in 9 (4.2%). The VFIms resolved within 1-90 days in all 8 patients with available follow-up of 1-3 months. One patient required endotracheal intubation. The 9 ASLIm patients had significantly higher rates of hoarseness and a history of diabetes mellitus. There was no group difference in the need to secure the airway. CONCLUSIONS: VFIm is an apparently uncommon finding among patients with ASL. It appears to be usually transient, short-lasting, and full recovery can be expected. VFIm did not alter the ASL course, nor did it put our patients at increased risk for the need for intervention to secure the airway. LEVEL OF EVIDENCE: 4.
