Early outcomes of osteofascial versus osteocutaneous fibula free flap mandibular reconstruction.

BACKGROUND: This study compares early outcomes of osteofascial fibula free flap (OF-FFF) with donor-site primary closure and osteocutaneous (OC) FFF with donor-site skin grafting in segmental mandibular reconstruction. METHODS: A retrospective chart review of FFF mandibular reconstruction patients (2006-2022) divided into OF-FFF and OC-FFF groups. Clinical data, operative parameters, and early postoperative outcomes (≤ 90 days) were analyzed. RESULTS: The study included 67 patients (39 OF-FFF, 28 OC-FFF). OF-FFF had significantly lower donor-site complications (12.8% vs. 53.6%, p < 0.001) and revision surgeries (7.7% vs. 35.7%, p = 0.004) compared to OC-FFF. Recipient-site (28.2% vs. 25%, p = 0.77) and flap (15.4% vs. 17.9%, p > 0.99) complications were comparable. CONCLUSIONS: OF-FFF mandibular reconstruction with donor-site primary closure is a safe and reliable technique associated with superior donor-site and comparable flap and recipient-site outcomes to OC-FFF, thus may be considered as a viable alternative to OC-FFF for selected patients.

4DCT in Discordant Parathyroid Adenoma Scans: Case Series and Meta-Analysis.

OBJECTIVE: To evaluate the accuracy of four-dimensional computerized-tomography (4DCT) for localizing parathyroid adenomas (PTAs) in cases with discordant or non-localizing ultrasonography (US) and Technetium-99 sestamibi (MIBI) scans. DATA SOURCES: Retrospective case series and systematic review. REVIEW METHODS: A case series and meta-analysis of patients diagnosed with primary hyperparathyroidism and discordant US and MIBI scans who underwent 4DCT prior to surgery. A comprehensive search for all relevant publications in the English literature between December 2006 and March 2022 was conducted for the meta-analysis. Patients undergoing parathyroidectomy between January 2015 and December 2021 were identified from the institutional electronic database for the case series. All studies were analyzed for sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the 4DCT adenoma localization capabilities. RESULTS: Thirteen retrospective studies that included 379 patients and one case series that included 37 patients were identified and analyzed. A per-patient analysis revealed sensitivity for lateralization to the correct side (n = 181) ranging from 80% to 100% with a fixed effects model of 89% (95%confidence interval [CI]: 82%-93%) and a PPV for lateralization ranging from 63%-95% with a random effects model of 87% (95% CI: 77%-95%). Sensitivity of localization to the correct quadrant (n = 172) ranged from 53% to 100% with a random effects model of 90.4% (95% CI: 76%-99%), and the PPV for localization ranged from 52% to 100% with a random effects model of 82% (95% CI: 73%-89%). CONCLUSION: 4DCT enhances imaging capabilities of localizing PTAs in cases of discordant or non-localizing US and MIBI scans. LEVEL OF EVIDENCE: NA Laryngoscope, 134:2198-2205, 2024.

Antibiotics or Tonsillectomy for Adult Recurrent Tonsillitis: Analyzing the Lesser of Two Evils.

OBJECTIVE: To determine the best timing for surgical intervention for adults with recurrent tonsillitis (RT). METHODS: A Markov model was constructed using variables and ranges based upon a literature review. A 1-way sensitivity analysis was performed to evaluate the number of yearly bouts at which each algorithm (antibiotics or tonsillectomy) would be favored. A Monte-Carlo probabilistic sensitivity analysis was calculated for gains and cost. Model outcomes were measured with quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICER) for tonsillectomy versus repeat antibiotic treatment. RESULTS: Patients expected to sustain a single annual tonsillitis event will have a negative QALY of 0.02 if treated with surgery and those with 2 annual events will have a QALY gain from undergoing tonsillectomy of 0.01, 3 events = 0.03, 4 events = 0.05, 5 events = 0.07, 6 events = 0.09, 7 events = 0.1, and 8 events = 0.11. These gains became meaningful only after 2 years of recurrent bouts. The average cost of tonsillectomy was 3,238 USD, and the overall average cost of RT was 7,069 USD (an incremental cost of 3,831 USD). The ICER of tonsillectomy over antibiotic treatment for 1 QALY gain was 44,741 USD. CONCLUSION: Adult patients who sustain more than 3 annual bouts of tonsillitis over a period of at least 2 years will gain QALY after tonsillectomy. These gains increase proportionally to the number of yearly events and perennial episodes. The incremental costs of tonsillectomy fail to meet the NICE guidelines but are within other acceptable reference ranges. LEVEL OF EVIDENCE: NA Laryngoscope, 134:2153-2161, 2024.

Functional outcome following intracapsular resection of head and neck peripheral nerve sheath tumors: a retrospective cohort.

BACKGROUND: Intracapsular resection of head and neck peripheral nerve sheath tumors (PNST) has emerged as a nerve-preserving technique compared to en bloc resection. The aim of this study was to evaluate and compare the functional outcome of both surgical techniques performed at a single tertiary referral center. METHODS: This is a retrospective cohort of patients with head and neck PNST undergoing surgical resection from 2011 to 2021 at the Tel Aviv Sourasky Medical Center. Demographic data, the nerve of origin and surgical technique, including the use of intraoperative nerve monitoring were recorded and analyzed in association with postoperative functional outcomes. RESULTS: Overall, 25 patients who had a cervical or parapharyngeal PNST resected were included. Nerve function was preserved in 11 of 18 patients (61%) who underwent intracapsular resection, while all those who underwent en bloc resections inevitably suffered from neurologic deficits (100%, N = 7). Sympathetic chain origin and an apparent neurologic deficit pre-operatively were associated with postoperative neural compromise. CONCLUSION: Improved functional outcome can be anticipated following intracapsular resection of extracranial head and neck PNST compared to complete resection, particularly in asymptomatic patients.

Mutated TP53 in Circulating Tumor DNA as a Risk Level Biomarker in Head and Neck Squamous Cell Carcinoma Patients.

Circulating tumor DNA (ctDNA) has been suggested as a surrogate biomarker for early detection of cancer recurrence. We aimed to explore the utility of ctDNA as a noninvasive prognostic biomarker in newly diagnosed head and neck squamous cell carcinoma (HNSCC) patients. Seventy HNSCC specimens were analysed for the detection of TP53 genetic alterations utilizing next-generation sequencing (NGS). TP53 mutations were revealed in 55 (79%). Upon detection of a significant TP53 mutation, circulating cell-free DNA was scrutinized for the presence of the tumor-specific mutation. ctDNA was identified at a minimal allele frequency of 0.08% in 21 out of 30 processed plasma samples. Detectable ctDNA correlated with regional spread (N stage ≥ 1, p = 0.011) and poorer 5-year progression-free survival (20%, 95% CI 10.9 to 28.9, p = 0.034). The high-risk worst pattern of invasion (WPOI grade 4-5) and deep invasion were frequently found in patients whose ctDNA was detected (p = 0.087 and p = 0.072, respectively). Detecting mutated TP53 ctDNA was associated with poor progression-free survival and regional metastases, indicating its potential role as a prognostic biomarker. However, ctDNA detectability in early-stage disease and the mechanisms modulating its release into the bloodstream must be further elucidated.

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.

Revisiting Age Criterion for Surgery in Asymptomatic Primary Hyperparathyroidism.

OBJECTIVE: To revisit the current age criterion (50 years) for surgical candidacy in patients diagnosed with asymptomatic primary hyperparathyroidism (PHPT). STUDY DESIGN: A predictive model relying on past publications using the electronic databases "PubMed," "Embase," "Medline," and "Google Scholar." SETTING: Hypothetical large cohort. METHODS: A Markov model was constructed, based on relevant literature, to compare 2 potential treatment algorithms for asymptomatic PHPT patients, parathyroidectomy (PTX), and observation. The various potential health states were characterized for the 2 treatment options and included potential surgical complications, end-organ deterioration, and death. A 1-way sensitivity analysis was performed to calculate the quality-adjusted life year (QALY) gains of both strategies. A Monte-Carlo simulation for 30,000 subjects was performed and cycled per annum. RESULTS: On the basis of the model's assumptions, the QALY value for the PTX strategy was 19.17 versus 17.82 for the observation strategy. The incremental QALY gains for various ages according to the sensitivity analyses for PTX in comparison to observation were: 2.84 QALY for 40-year-old patients, 2.2 QALY for 50-year-old patients, 1.81 QALY for 55-year-old patients, 1.35 QALY for 60-year-old patients, and 0.86 QALY for 65-year-old patients. The incremental QALY is below 0.5 after the age of 75 years. CONCLUSION: This study found PTX to be advantageous for asymptomatic PHPT patients older than the current age criterion of 50 years. The calculated QALY gains support a surgical approach for medically fit patients in their 50s. The current guidelines for the surgical treatment of young asymptomatic PHPT patients should be revisited by the next steering committee.

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.

The impact of eustachian tube function on intra-tympanic steroid administration.

OBJECTIVES: This study investigated the impact of eustachian tube (ET) function (ETF) on therapeutic success on candidates for intra-tympanic administration of steroids (ITAoS), due to idiopathic sudden sensorineural hearing loss (ISSNHL). METHODS: Medical chart review in two university-affiliated medical centers was performed. Included were consecutive adult patients diagnosed with unilateral ISSNHL between 2012 and 2019 who were treated with ITAoS due to incomplete or no recovery following systemic steroidal therapy. ETF was assessed by means tympanometry, before the initiation of ITAoS. The cohort was divided into an ET dysfunction group (ETD(+)) and a functioning ET group (control: ETD(-)). The audiologic response to treatment was recorded at the last follow-up. RESULTS: A total of 64 suitable patients [median (interquartile, IQR) age 49 (38-63) years] were enrolled. The ETD(+) group included 20 patients and the remaining 44 patients served as controls. Demographic and clinical parameters were not significantly different between the two groups at presentation. Hearing thresholds were improved significantly better, at frequencies 250, 500, 1, 2, 4, and 8 kHz (p = 0.001-0.040) in the ETD(+) group. CONCLUSION: ETD(+) is associated with better efficacy of ITAoS.

Is tympanic infrared thermometry valid in non-naive tympanic membranes?

OBJECTIVE: To investigate the impact of with tympanostomy tubes (TT) on infrared tympanic membrane thermometer (ITMT) results and to provide a systematic review of ITMT results in non-naïve tympanic membranes. STUDY DESIGN: Original prospective blinded case series and systematic literature review. SETTINGS: A single tertiary university-affiliated medical center. METHODS: ITMT measurements of patients with unilateral TT and contralateral naïve control ear were randomly conducted by a single investigator blinded to the TT side before and after cerumen was removed from the external auditory canals. A systematic literature search of "MEDLINE" via "PubMed," "Embase," and "Google Scholar" on comparable published cases was performed. RESULTS: The mean paired differences (95% confidence interval [CI]) between ventilated and non-ventilated ears before and after cerumen removal were 0.08 ºC/0.14 ºF (-0.04 to 0.19 ºC/- 0.07º-0.34º) and 0.62 ºC/1.12 ºF (0.04-0.25 ºC/0.07-0.45 ºF), respectively (P < 0.001 and P = 0.01, respectively). CONCLUSION: These findings support the validity and accuracy of ITMT in the setting of ventilated ears.

Pre-resection Intraoperative Core Biopsies in Oral Tongue Cancer-A Pilot Study.

OBJECTIVE: To assess a novel intraoperative core biopsy technique to provide enhanced guidance in partial glossectomies. METHODS: All patients diagnosed with squamous cell carcinoma of the oral tongue were eligible for study participation. Following anesthesia, the planned resection and three points midway between the gross tumor and the intended ablation were marked. A core biopsy was performed with a needle spring on each point and sent for frozen sections. The initially planned resection was executed if the cores returned free of tumor. In case of a positive core biopsy, a new 1-1.5 cm margin was marked around that point. The main outcome measure was the closest final margin diameter, especially the deep ones. Other outcome measures were the core biopsies' sensitivity, specificity, and negative predictive value. Complications were recorded. RESULTS: The final margins of 10 patients undergoing intraoperative core biopsies and 20 matched controls were analyzed. One patient had two positive cores and final negative margins after modifying the resection accordingly. Another patient had a positive biopsy diagnosed only on final pathology, and one close final margin. Patients that were operated with the new technique had larger margins compared to the controls: median (interquartile range) closest margin 5.95 (3.97; 9.63) mm versus 4 (2.25; 5) mm (p = 0.074) and median deep margin 8.6 (6.16; 10) mm versus 5 (3;10) mm (p = 0.411), respectively. There were no complications. CONCLUSION: A novel pre-resection intraoperative biopsy technique is presented. Core biopsies taken during glossectomies have the potential to prevent inadequate margins.

Fast-Tracking of Publication Times of Otolaryngology Papers During the COVID-19 Pandemic.

To study the impact of the COVID-19 pandemic on journal processing times before publication in the field of otolaryngology-head and neck surgery (ORL-HNS). Online search of original papers published in selected ORL-HNS journals in terms of times from submission to acceptance (S-A), acceptance to first online publication (A-P), and submission to online publication (S-P). Papers were divided into those published in the pre-COVID-19 era and those during the COVID-19 era. The latter were further divided into unrelated to COVID-19 and related to COVID-19. A total of 487 articles from 5 selected ORL-HNS journals were included, of which 236 (48.5%) were published during the pre-COVID-19 era and 251 (51.5%) were published during the COVID-19 era. Among them, 180 (37%) papers were not related to COVID-19, and 71 (14.5%) were related to COVID-19. The S-A duration of COVID-19-related articles was significantly shorter compared to papers submitted in the pre-COVID-19 era and to papers submitted in the COVID-19 era but unrelated to COVID-19 (median 6-34 days compared to 65-125 and 46-127, respectively) in all 5 journals. The most prominent reductions in S-A and S-P times were documented in the laryngology and otology/neurotology disciplines, respectively. Processing times of the included papers were significantly shorter in most of the selected ORL-HNS journals during the COVID-19 era compared to the pre-COVID-19 era. COVID-19-related papers were processed more rapidly than non-COVID-19-related papers. These findings testify to the possibility of markedly expediting S-P times and hopefully set a precedent for post-pandemic publishing schedules.

Diagnostic efficacy of positron emission computerized tomography scans in suspicious laryngeal findings postorgan preservation treatment.

BACKGROUND: Larynx preservation protocols (LPP) for glottic primary squamous cell carcinoma has gained popularity worldwide. Direct laryngoscopy (DL) with biopsy is mandated when recurrence is suspected. The efficacy of 18Fluoro-deoxy-glucose positron emission computerized tomography (PET-CT) as alternative first-line diagnostic investigation in suspected recurrence was evaluated. METHODS: A retrospective study of patients with suspicious fiber-optic findings at more than 12 weeks after LPP. Sensitivity, specificity, and the negative predictive value (NPV) of DL and PET-CT were compared. RESULTS: Seventy-two patients presenting 105 cases of suspicious events were included in this study. Fifty-two events were initially investigated by DL and 53 events by PET-CT. The sensitivity of DL and PET-CT was 56.25% and 100%, respectively. The NPV was 84% for DL and 100% for PET-CT (p = 0.015). CONCLUSION: Negative PET scans after LPP are highly accurate in ruling out recurrent/persistent disease and may spare the patient from negative biopsies.

Is Idiopathic Sudden Sensorineural Hearing Loss Seasonal?

OBJECTIVE: To investigate the circannual rhythm (seasonal incidence) of idiopathic sudden sensorineural hearing loss (ISSNHL). METHODS: Data were retrieved from the medical files of an original cohort of all consecutive patients with ISSNHL in a tertiary medical center between 2012 and 2020. A systematic literature search of "MEDLINE" via "PubMed," "Embase," and "Web of Science" on comparable published cases was performed. A Google Trends analysis of the term [sudden hearing loss] and related terms between 2014 and 2020 was also performed. RESULTS: Most of the published series (9/12) reported the highest ISSNHL incidence in the spring and the lowest in the winter (8/12). In our local series, the incidence during the winter was significantly lower than that for the other seasons by a factor of 0.69 (95% confidence interval, 0.65-0.77; p = 0.041; r = 0.36). Google Trends data showed no significant correlation between the calendric month and the incidence of ISSNHL in any of the analyzed countries ( p = 0.873, r2 = 0.029). CONCLUSION: The ISSNHL incidence was lowest during the winter season in our cohort and reported for other cohorts worldwide. Google Trends-based model analysis did not determine any circannual rhythm.

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.

The impact of thyroidectomy on obstructive sleep apnea: a systematic review and meta-analysis.

PURPOSE: Various thyroid pathologies are speculated to contribute to obstructive sleep apnea (OSA). The underlying mechanisms of the intricate relationship between OSA and thyroid structure and function, and whether thyroidectomy can alleviate OSA symptoms remain unclear. An assessment of the impact of thyroidectomy on OSA is warranted. METHODS: A systematic review of four electronic databases (PubMed (Medline), Embase, the Cochrane library, and ClinicalTrials.gov) was performed up to February 2022. The primary outcomes were preoperative and postoperative Apnea/Hypopnea Index (AHI), Epworth Sleepiness Scale (ESS), Berlin questionnaire scores, and continuous positive airway pressure (CPAP) use. A meta-analysis of continuous measures and odd ratios was conducted. Small-scale studies underwent a qualitative meta-analysis. RESULTS: Six cohort studies on 221 OSA patients who underwent thyroidectomies were included. The results showed that thyroidectomy was associated with significant reduction in postoperative AHI (Mean difference [MD], -6.39, 95% CI, -12.46 to -0.32), however, no significant association was found with CPAP withdrawal (Odd ratio [OR], 0.38, 95% CI, 0.12-1.18). Neither the Berlin questionnaire score (OR, 0.19, 95% CI, 0.03-1.17) nor the ESS improved postoperatively (MD, -1.04, 95% CI, -6.37 to 4.29). CONCLUSION: This meta-analysis provides a quantitative estimate for the effect of the thyroidectomy on OSA and suggests that thyroidectomy is associated with limited clinical improvement of polysomnographic measures. Future large-scale, well-designed prospective studies are necessary to validate these findings and to refine accordingly the preoperative assessment of both medical conditions individually and in combination.

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 rate of occult nodal metastasis in submandibular gland malignancies: A case series and meta-analysis.

OBJECTIVE: Submandibular gland (SMG) malignancies are exceedingly rare. Lymph node metastasis is one of the most important determinants of outcome in SMG malignancies. The aim of this study was to investigate the overall rate of occult neck nodal metastasis in SMG malignancies. STUDY DESIGN: The study design is a meta-analysis of all studies on patients with a primary SMG malignancy, without evidence of neck nodal metastasis, who underwent an elective neck dissection (END). The search strategy identified 158 papers that appeared in print from January 1980 to July 2020. All eligible patients from the Tel-Aviv Medical Center were analyzed and consolidated into a case series. A total of 12 retrospective studies that included 306 suitable patients met inclusion criteria. RESULTS: The risk for occult metastasis in primary SMG malignancies was 0.0% to 50.0%, with a fixed effect model of 19.52% (95% CI, 14.9%-24.5%). The analyzed studies included a wide range of pathologies. The most common malignancies were adenoid cystic carcinoma and mucoepidermoid carcinoma. CONCLUSIONS: The overall rate of occult neck metastasis in SMG malignancies is relatively high, and an END should be the default intervention in these cases. An END is unwarranted in tumors judged clinically to be low stage and low grade.

Accuracy of Pathology Reports on Neck Dissection Specimens: A Retrospective Case Series Study.

BACKGROUND: Accuracy of the number and location of pathological lymph nodes (LNs) in the pathology report of a neck dissection (ND) is of vital importance. OBJECTIVES: To quantify the error rate in reporting the location and number of pathologic LNs in ND specimens. METHODS: All patients who had undergone a formal ND that included at least neck level 1 for a clinical N1 disease between January 2010 and December 2017 were included in the study. The error rate of the pathology reports was determined by various means: comparing preoperative imaging and pathological report, reporting a disproportionate LN distribution between the different neck levels, and determining an erroneous location of the submandibular gland (SMG) in the pathology report. Since the SMG must be anatomically located in neck level 1, any mistake in reporting it was considered a categorical error. RESULTS: A total of 227 NDs met the inclusion criteria and were included in the study. The study included 128 patients who had undergone a dissection at levels 1-3, 68 at levels 1-4, and 31 at levels 1-5. The best Kappa score for correlation between preoperative imaging and final pathology was 0.50. There were nine cases (3.9%) of a disproportionate LN distribution in the various levels. The SMG was inaccurately reported outside neck level 1 in 17 cases (7.5%). CONCLUSIONS: At least 7.5% of ND reports were inaccurate in this investigation. The treating physician should be alert to red flags in the pathological report.
