RESUMEN
OBJECTIVE: Temporal bone pneumatization (TBP) is speculated to serve as a shock absorber in temporal bone fractures (TBF), directing the fracture line away from vital structures. This study correlates TBP extent with TBF patterns and preservations of vital TB structures. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary referral medical center. METHODS: All TBF patients referred to a single tertiary center 2017 to 2023 were evaluated. A pneumatization index score for each of their TBs was derived by counting automated-voxel density in a 0 to 100 scale. Results were correlated to the TBF type and the violated structure(s). The ossification index was compared to previously detailed qualitative classification systems of TBP. RESULTS: One hundred and forty-five patients were enrolled (mean age 43 ± 17 years). Kinematics were motor vehicle accidents (46%), scooter (15%), bicycle (14%), falls (13%), and assaults (8%). The mastoid ossification index we used showed a strong correlation to all qualitative classification systems (sigmoid = 0.829; labyrinthine = 0.849; carotis = 0.863, infralabyrinthine = 0.869, all P < .001). The pneumatization index strongly correlated with capsule-violating TBFs, with a mean of 44 ± 23 for otic capsule-sparing TBF and 61 ± 20 for otic capsule-violating (OCV) TBF (P < .001). The facial nerve was violated in 30 patients. Facial canal (FC) involvement was not correlated to the ossification index: it was 49 ± 23 for FC-sparing and 44 ± 23 for FC-violating (P = .620). CONCLUSION: TBP serves as a protective mechanism against OCV TBF. The more pneumatized the TB, the less likely the otic capsule will be violated in the event of a TBF with the exception of the carotid and FCs. TBP index is in strong agreement with qualitative TBP classification systems.
RESUMEN
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.

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.

OBJECTIVES: To assess the correlation between inflammatory markers (IM) and hearing loss (HL) in a large cohort of apparently healthy individuals. DESIGN: A cross sectional study. SETTING: Tel-Aviv Medical Center (a tertiary referral center) Inflammatory Survey Participants Individuals who attended the Tel-Aviv Medical Center Inflammatory Survey (TAMCIS) for a routine annual health check. RESULTS: Out of 2,500 individuals included in the final study cohort, 1,170 (47.3%) had some hearing impairment. Those with a hearing loss in 1 or both ears had significantly higher levels of neutrophils, lymphocytes, neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, and red blood cell counts. There was a difference between low- and high- frequencies losses associated with the inflammatory status. CONCLUSIONS: IM levels were associated with the presence of a HL, supporting a link between inflammatory changes and hearing loss.

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.

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.

BACKGROUND: Pilonidal sinus is a chronic, inflammatory condition. Controversy exists regarding the best surgical management for pilonidal sinus, including the extent of excision and type of closure of the surgical wound. OBJECTIVES: To assess the short- and long-term outcomes and success rate of the trephine procedure for the treatment of pilonidal sinus. METHODS: A retrospective observational cohort study was conducted at a single center. Patients who underwent trephine procedure between 2011 and 2015 were included. Data collection included medical records review and a telephone interview to establish long-term follow-up. RESULTS: A total of 169 patients underwent the trephine technique for the repair of pilonidal sinus. Follow-up included 113 patients, median age 20 years. Initial postoperative period, 35.6% recalled no pain and 58.6% reported a mild to moderate pain. Postoperative complications included local infection (7.5%) and mild bleeding (15.1%). On early postoperative follow-up, 47.1% recalled no impairment in quality of life, and 25%, 21.2 %, and 6.7% had mild, moderate and sever disturbance respectively. The median time to return to work or school was 10 days. At a median follow-up of 29 months (IQR 19-40), recurrence rate was 45.1% (51/113), and 38 (33.9%) of the patients underwent another surgical procedure Overweight, smoking, and family history were associated with higher recurrence rate. CONCLUSIONS: The trephines technique has a significant long-term recurrence rate. Short-term advantages include low morbidity, enhanced recovery, and minimal to mild postoperative impairment to quality of life. The trephine procedure may be justified as a first treatment of pilonidal disease.

PURPOSE: Radiotherapy (RT) is widely used for early glottic cancer. Patients failing this treatment are referred to surgical management of their disease. Salvage partial laryngectomy (SPL) has the advantage of preserving laryngeal function with total laryngectomy (TL) remaining as a last resort. The purpose of this study was to determine the efficacy of SPL in preventing total laryngectomy, following failed RT, for early glottic cancer. METHODS: A meta-analysis of all published English literature was performed. All publications that included patients undergoing SPL were reviewed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) reporting guidelines. The search strategy identified 154 relevant articles. A total of 15 retrospective studies that included 323 suitable patients were subsequently analyzed in this meta-analysis. The main outcome measure was the rate of laryngectomy-free survival (LFS) following SPL. The indications for salvage TL (i.e., disease recurrence and poorly functional larynxes) as well as subgroup analyses for open and trans-oral SPLs were also calculated. RESULTS: The overall rate of LFS following SPL was 81.2% (fixed effects model range: 75.7-86.8%). Salvage TL following SPL were performed in 96.8% due to disease recurrence and in 3.2% to poorly functional larynxes. A subgroup analysis showed a 90.4% LFS after open SPL and 78.6% following trans-oral SPL. CONCLUSION: A high rate of successful salvage partial laryngectomies, regardless of surgical technique, is to be anticipated in well-selected patients after RT failure.

Importance: Developing a telemedicine tool to discriminate between patients who need urgent treatment for sudden sensorineural hearing loss (SSNHL) from those who do not takes on special importance during the COVID-19 pandemic. Objective: To explore the feasibility of a telemedicine model to assist in the evaluation of new-onset unilateral sudden hearing loss (SHL) among patients who do not have access to medical resources, especially during the COVID-19 pandemic. Design, Setting, and Participants: This prospective cohort investigation of a telemedicine model was conducted at a tertiary referral medical center between May 2020 and January 2021, with the interpreting physician blinded to the results of formal audiograms. The study included a consecutive sample of adult patients (aged ≥18 years) referred to the otolaryngology emergency department in our medical center with the chief complaint of new-onset unilateral SHL. Interventions: The telemedicine model comprised 2 sequential steps: a Weber test using the Hum Test and a smartphone-based vibration, and uHear app-based audiometry. Main Outcomes and Measures: Discrimination between patients with and without SSNHL by using the telemedicine model. All diagnoses subsequently confirmed by a formal audiogram. Results: Fifty-one patients with new-onset unilateral SHL participated in the study study (median age, 45 [range, 18-76] years; 28 [54.9%] men). The sensitivity and specificity of the telemedicine model for fulfilling the audiometric criteria of SSNHL (loss of ≥30 dB in ≥3 consecutive frequencies) were 100% (95% CI, 84%-100%) and 73% (95% CI, 54%-88%), respectively. The PPV was 72% (95% CI, 53%-87%), the NPV was 100% (95% CI, 85%-100%), and the accuracy was 84.3% (95% CI, 71%-93%). Although 8 participants had false-positive results, all of them had SSNHL that did not meet the full audiometric criteria. Conclusions and Relevance: The telemedicine model presented in this study for the diagnosis of SSNHL is valid and reliable. It may serve as a primary tool for the discrimination between patients in need of urgent care for SSNHL from those who are not, especially during the COVID-19 pandemic.

BACKGROUND: High serum bilirubin levels have been shown to be associated with an improved pulmonary function test results. Their potential ability to similarly benefit pulmonary function in an environment of polluted air has not been tested. We retrospectively analyzed data of 15,605 apparently healthy individuals in order to evaluate the effect of serum bilirubin levels on forced expiratory volume in 1 s (FEV1). METHODS: Individuals attended the Tel-Aviv Medical Center Inflammatory Survey for a routine annual health check between February, 2002 and June, 2009 and were divided into low, medium and high serum bilirubin levels. Their FEV1 results were compared under various levels of air pollution. Air pollution and weather data were obtained from air pollution monitoring stations of the Israeli Ministry of Environmental Protection. RESULTS: The elevated serum bilirubin concentrations on FEV1 were evaluated under moderate and high pollution levels FEV1 and were significantly higher in participants with high blood bilirubin levels compared to medium or low levels (p < 0.001 and p = 0.018, respectively). Participants with high levels of bilirubin had preserved FEV1 under exposure to high and medium pollution levels of both Nitrogen Oxide (NOx) and Carbon Monoxide (CO) pollutants (p = 0.003 and p = 0.022, respectively). The multivariate regression analysis revealed that the influence of bilirubin under conditions of air pollution remained significant even after adjustment for FEV1 confounders, but the interaction was not significant. CONCLUSIONS: Elevated serum bilirubin concentrations are associated with preserved lung function in healthy individuals in Israel exposed to high levels of air pollution.

BACKGROUND: Fractional exhaled nitric oxide (FeNO) is a biomarker for eosinophilic inflammation used for diagnosis and monitoring of asthma. High FeNO indicates significant airway eosinophilia and steroid-responsive airway inflammation. Some children with asthma have extremely high FeNO levels, but whether these levels represent a different asthma phenotype compared with those with mildly elevated FeNO is unclear. The objective of this study is to investigate whether the extent of high FeNO levels correlates with clinical phenotype, asthma control, comorbidity, and pulmonary function test (PFT) findings in children with asthma. METHODS: Anthropometric data, daytime and nighttime symptoms, controller treatment, comorbidity, and PFT findings were retrieved from the Pediatric Pulmonology Unit database (2014-2020) and correlated with FeNO levels in pediatric asthma patients with high FeNO levels. RESULTS: Two-hundred children and adolescents with high FeNO levels (range 36-227 ppb) were included. Within this range, higher FeNO levels positively correlated with increased daytime and nighttime symptoms (p = .013 and p = .01, respectively) and poorly controlled asthma (p = .034). A FeNO level of ≥80 ppb was the cutoff for significantly more severe daytime and nighttime symptoms and very poorly controlled asthma compared with levels <80 ppb (p = .004, p = .005, and p = .036, respectively). No correlation was found between FeNO and controller treatment, comorbidity, and PFT performance. CONCLUSION: In pediatric asthma patients, high FeNO levels correlate with increased symptom severity and poor asthma control. A FeNO level of ≥80 ppb may serve as an objective indicator for severe asthma.

OBJECTIVES/HYPOTHESIS: The effects of different electrocautery power settings on mucosal contraction and margin status in the oral cavity have not been well established. The aim of this study was to examine how different levels of electrocautery energy outputs affect oral mucosal tissue margins. STUDY DESIGN: Animal model. METHODS: A model of 23 adult rats was used (two specimens per rat). After anesthetizing the animals, a 6-mm biopsy punch marked the resection margin on the buccal mucosa (one per cheek). The specimens were excised by means of three energy levels, a cold knife, and monopolar diathermy that was set on either 20 W or 30 W cut modes. The specimens were evaluated for extent of contraction. RESULTS: A total of 45 samples were obtained and measured, including 15 specimens in the cold-knife group, 15 specimens in the 20 W group, and 15 specimens in the 30 W group. The median diameters of the specimens after resection were 4.5 mm for the cold-knife group (interquartile range [IQR] = 4.0-5.0), 3.5 mm for the 20 W group (IQR = 3.5-4.0), and 2.8 mm for the 30 W group (IQR = 2.5-3.0). Specimen contraction was 25.0%, 41.7%, and 53.3%, respectively. The difference in shrinkage between each pair was statistically significant: cold knife versus 20 W, P = .001; cold knife versus 30 W, P < .0001; and 20 W versus 30 W, P < .001. CONCLUSIONS: Diathermy power settings result in a significant difference of mucosal tissue contraction, with higher outputs resulting in a narrower mucosal margin. It is imperative that the surgical team take into consideration the diathermy settings during initial resection planning. Laryngoscope, 131:E1514-E1518, 2021.

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.

RESUMEN
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.

To study the effect of very advanced maternal age on perinatal outcomes. A retrospective cohort study of women aged 45 years and above, who delivered ≥22 weeks of gestation in a single tertiary center between 1/ 2011 and 12/ 2018. Maternal and neonatal outcomes were compared between women ≥50 years and women of 45-49 years at delivery. Of 83,661 parturients, 593 (0.7%) were 45-49 years old and 64 (0.07%) were ≥50 years old. Obstetrical characteristics were comparable, though the rate of chronic hypertension and preeclampsia with severe features were greater in women ≥50 years (6.2% vs 1.4%, p = 0.04, 15.6% vs 7.0%, p = 0.01, 95% CI 0.19-0.86, respectively). Elective cesarean deliveries were independently associated with advanced maternal age ≥50 (OR 2.63 95% CI 1.21-5.69). Neonatal outcomes were comparable for singletons, but rates of ventilatory support and composite severe neonatal outcomes were higher in twin pregnancies of women ≥50 years (42.8% vs 13.5%, p = 0.01, and 21.4% vs 4.0%, p = 0.03, respectively). Healthy women ≥50 have higher elective cesarean rates, despite similar maternal and neonatal characteristics.

BACKGROUND: Lung function is inversely associated with coronary heart disease and cardiovascular disease. High-sensitive cardiac troponin T (hs-cTnT) was recently found to represent early subclinical cardiac disease even in healthy individuals. We explored the inter-relationship between lung function and hs-cTnT and the changes over time in these two measurements. METHODS: Lung function test and hs-cTnT were determined in apparently healthy individuals from the Tel Aviv Medical Center Inflammatory Survey. Participants with normal lung function were followed up for 5 years in order to evaluate the effect of lung function deterioration on hs-cTnT levels. The correlation between annual Forced vital capacity (FVC) % predicted decline and hs-cTnT levels were analyzed. RESULTS: A 5-year follow-up of 2,618 participants with normal lung function at baseline revealed a mean annual FVC deterioration of 31.9 (±91.3) ml/year. Lung function decline >5% was associated with an increased risk of having hs-cTnT >5â¯ng/L (Exp. ßâ¯=â¯1.55 1.20-1.99, pâ¯=â¯0.001). Delta FVC between two consecutive visits was inversely correlated with an increase of hs-cTnT (râ¯=â¯-0.24, pâ¯<â¯0.001). CONCLUSIONS: Deterioration of lung function predicts elevated troponin levels and may be a sign of early subclinical cardiac disease.

PURPOSE: To compare short- and long-term quality of life (QOL) scores in patients undergoing mandibular resection and reconstruction. MATERIALS AND METHODS: All the patients who underwent resection and reconstruction of the mandible between 2000 and 2015 at a large tertiary center were retrospectively reviewed. Their QOL was measured by the University of Washington QOL questionnaire. Between 12 and 189 months (median 83.5 months) had elapsed since the end of treatment. The QOL of the short-term (< 5 years) and long-term (> 5 years) follow-up groups was compared and analyzed. RESULTS: Fifty-eight patients completed the questionnaire. The scores for physical function, emotional function, activity, recreation, and taste domains were significantly higher for the long-term follow-up group. The activity and pain domains posed a significant problem for significantly more patients in the short-term follow-up group. CONCLUSION: Comparison of the short- and long-term QOL scores of patients undergoing mandibular resection and reconstruction revealed that the scores for the latter were significantly higher in several domains. This finding might be indicative of a cumulative effect of time on patients' QOL, even many years post-treatment.

BACKGROUND: While chronic respiratory diseases are among the leading causes of mortality and morbidity worldwide, little is known about the effect of blood eosinophil levels on lung function trajectories among healthy individuals. METHODS: We analyzed data of apparently healthy individuals (n=18,089) recruited for the Tel Aviv Medical Center Inflammation Survey. Blood eosinophil levels were compared between participants with normal and those with abnormal lung function. Multivariate regression was used to assess the OR of forced expiratory volume in 1 second (FEV1) deterioration according to baseline eosinophils in subjects with normal lung function (n=4,141) during a follow-up period of 4 years. RESULTS: Participants with an abnormal, as opposed to a normal, pulmonary function test (PFT) (n=1,832, 10.1%) had significantly higher eosinophil levels, expressed as a percentage or count (2.99%±2.00% compared to 2.67%±1.88% and 0.2210e3/µL±0.163/µL compared to 0.1810e3/µL±0.183/µL, respectively; P<0.001 for both). Among participants with a normal PFT at baseline, those with an eosinophil percentage higher than 4% showed a higher risk for FEV1 decline above 60 mL/year (OR=1.199, 95% CI=1.005-1.431, P=0.044). CONCLUSION: Our study suggests that higher blood eosinophil levels can predict PFT deterioration even in apparently healthy subjects, implying that these individuals could benefit from frequent lung function evaluation.
