Objective: Recent studies found that mobile phone users had a significantly greater risk of having elevated thresholds in speech frequencies. This study investigated the correlation between the laterality of sudden sensorineural hearing loss, handedness and the preferred ear for mobile phone use. Methods: The study included all patients who presented with sudden sensorineural hearing loss to the Department of Otolaryngology - Head and Neck Surgery in our tertiary referral medical centre between 2014 and 2016. Patients were asked to indicate their dominant hand and preferred ear for mobile phone use. Results: The study comprised 160 patients. No correlation was found between the dominant hand or preferred ear for mobile phone use and the side of sudden sensorineural hearing loss. There was no correlation between the side of the sudden sensorineural hearing loss (preferable or non-preferable for mobile phone use) and audiometric characteristics. Conclusion: No correlation was found between the laterality of ears used for mobile phone and sudden sensorineural hearing loss. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: To analyze recurrence patterns of chronic sinusitis with nasal polyposis (CRSwNP) in patients who underwent complete FESS and identify predisposing factors for different patterns of recurrence., Methods: Retrospective analysis of patients with CRSwNP who underwent complete FESS at our tertiary medical center. Recurrence patterns were classified into edema, polyp and normal endoscopy, as well as into early (within 6 months) and late recurrence. Statistical analysis to identify risk factors for recurrence included univariate, multivariate logistic regression and cox regression models., Results: 114 patients were included with an average follow-up of 27 months. 91% were categorized as type-2 inflammation. Recurrence was observed in 65.8% of patients within a mean of 12.9 months. 46.7% had polyp recurrence while 53.3% had edema recurrence. Early recurrence was observed in 41%. Serum eosinophilia > 500 cells/uL was found to be significantly associated with recurrence (RR = 1.62, p-value = 0.046), and particularly with polyp recurrence (RR = 3.9, p-value = 0.001). No predictive factors for early recurrence were identified. Edema recurrence was managed with intranasal corticosteroids while polyp recurrence required systemic therapy including biologic therapy., Conclusions: In this study, two thirds of patients experienced post operative recurrence, either mucosal edema or nasal polyps, with similar frequency during an average follow up of over 2 years. Early recurrence was noted in 41% of recurrent cases. Serum eosinophils > 500 cells/uL was the only risk factor for recurrence on multivariate analysis, more accurate markers are needed for improved treatment allocation to CRSwNP patients., (© 2024.

- Abstract
Purpose: To assess a novel Virtual Reality (VR) tool designed to enhance understanding of the nasal anatomy in patients eligible for DCR surgery., Methods: Preoperative Computed Tomography (CT) scans of the orbit were obtained and loaded as DICOM (Digital Imaging and Communications in Medicine) files onto the D2P software (3D Systems Inc. Littleton, CO) for tissue segmentation and 3D model preparation. Segmentation was performed on several anatomical structures, including the skull, lacrimal sac, nasal septum, inferior and middle turbinate. The resulting 3D model was visualized using a VR headset. After completing the segmentation procedure, ten cases were evaluated by a panel of six surgeons, including both senior and resident physicians from ENT and oculoplastic specialties., Results: The dataset under examination comprised images from 10 preoperative CT scans of the orbits of patients eligible for Endo-DCR. When evaluating the CT using the VR tool, in 73.3% of the cases ENT surgeons were right about the side of pathology, while only 43.3% ophthalmologists were right (chi-square, p = .018). In 72.8% of the cases ENT surgeons were evaluated right that there is a septum deviation, while only in 47.2% of the cases the ophthalmologists were right (chi-square, p = .094).When evaluating the CT using the VR tool, in 60% of the cases consultants were right about the pathology, while 57.7% of the residents were right (chi-square, p = .853). In 81.7% of the cases consultants were evaluated right that there is a septum deviation, while only in 58.3% of the cases the ophthalmologists were right (chi-square, p = .198)., Discussion: ENT surgeons, as well as consultants, interpreted the CT better than the ophthalmologists and residents. Surprisingly, the VR system did not help them to interpret the CT better. Further, more extensive studies should be done to build a VR system that assists in the correct interpretation of the preoperative CT before DCR surgery as well as during DCR surgery.

- Abstract
Objectives: Postoperative antibiotic therapy is a common practice following septoplasty with intra-septal splints placement (ISS), even though there is a lack of evidence to support it. We sought to investigate the role of antibiotic therapy in septal surgeries with the placement of ISS., Design: A retrospective comparative study was conducted using the electronic charts of adult patients who underwent septoplasty with the placement of ISS with or without turbinate reduction. Nasal cultures were taken routinely during surgery as part of the department's protocol for monitoring infectious diseases. The ISS were also routinely examined for the presence of bacteria after their removal on the eighth day following surgery., Setting: A large otolaryngology department in a tertiary medical center., Participants: Adult patients who underwent septoplasty in our institution., Main Outcome Measures: We analyzed all post-operative infections to search for risk factors in the cohort., Results: Post-operative infection rates following septoplasty with ISS were low at 6%, which is consistent with previously published rates. Infection rates were significantly higher in patients who were not treated with antibiotics (OR = 8.2, 95%CI: 1.63-41.1; p = .01, φ = 0.04). Diabetes was associated with an increased risk of postoperative infection regardless of prophylactic antibiotic therapy (OR = 5.2, 95%CI: 1.15-23.5; p = .032, φ = .04). The detection of Klebsiella pneumonia before surgery was associated with an increased rate of postoperative infection (OR = 16.6, 95%CI: 3.02-91.54; p = .001, φ = 0.12)., Conclusions: Patients undergoing septoplasty with the placement of ISS are at increased risk of gram-negative bacterial colonisation, and development of postoperative nasal infection. A single preoperative dose of IV antibiotic therapy should be considered a potential prophylactic option for septoplasty with ISS., (© 2023 The Authors.

- Abstract
Objective: To study the applicability of transnasal echography for the internal carotid artery (ICA) imaging during endoscopic procedures, primarily nasopharyngectomy., Study Design: Non-randomized controlled cohort., Methods: The tip of a pediatric transducer for transesophageal echography was inserted into each nostril under endoscopic control and placed in the ipsilateral Rosenmuller's fossa. The ICA's internal diameter and distance between the nasopharyngeal wall and the artery's closest point were measured on each side. Two independent examiners measured the same parameters on the axial plane of the skull base computer tomography (CT). Agreement between CT and echography measurements was estimated by the Bland-Altman approach., Results: Twenty-seven ICAs (sides) were available for the echography-CT agreement analysis. Inter method agreement for both parameters was similar to the inter examiner agreement for the CT measurements., Conclusions: Our first study on endoscopic echography demonstrated that this method is applicable, potentially allowing safer transnasal surgery in the ICA vicinity., Level of Evidence: 3 Laryngoscope, 132:1184-1188, 2022., (© 2022 The American Laryngological, Rhinological and Otological Society, Inc.)

- Abstract
Background: Surgeons are often faced with concerns regarding the risks versus benefits of endoscopic sinus surgery (ESS) in elderly patients., Objective: To analyze the risk for complications of ESS in the elderly (age ≥70 years) compared to younger patients, with emphasis on octogenarians., Methods: Retrospective review of medical charts of adult patients who underwent ESS at a tertiary referral center during the years 2014 to 2018., Results: We compared 128 elderly patients with 276 matched younger patients. In the elderly group mean age was 76 years (range, 70-91 years ). Thirty-one elderly patients were 80 years or older. Surgical complications in the elderly patients were 3.9%. Minor complications were 2.3% and major complications were 1.7%. The surgical complications rate was similar in the younger group (8%, P value: .127). Medical complications were observed in 2.3% comparing to 0.7% in younger patients. Interestingly, age, revision surgery, extent and duration of surgery, and modality of anesthesia were not identified as risk factors. Only ischemic heart disease (IHD) was identified as a risk factor for complications in a multivariate analysis in elderly patients. Comparison of elderly patients younger than 80 years with octogenarians revealed no difference in complication rate between these groups., Conclusions: Overall, ESS was found to be a safe procedure in elderly patients compared to younger patients. Octogenarian patients should not be denied upfront surgery. IHD is a risk factor for complications in elderly patients.

- Abstract
Objectives/hypothesis: To describe the characteristics and severity of epistaxis in patients taking factor Xa inhibitors novel anticoagulants., Study Design: Retrospective cohort study., Methods: A study of adult patients hospitalized due to spontaneous epistaxis under the treatment of warfarin, rivaroxaban, or apixaban between the years 2011 and 2017 was performed. A control group of patients under antiplatelet therapy (acetylsalicylic acid, clopidogrel) was included. The mean follow-up periods in the warfarin, rivaroxaban, apixaban, and antiplatelet groups were 18, 14.5, 13.5, and 18.2 months, respectively. We compared demographics, location and severity of bleeding, treatment methods, and outcome between the groups., Results: The study included 109 patients (35 under factor Xa inhibitors), the majority of whom presented with anterior epistaxis (68%). The antiplatelet group had more episodes of epistaxis prior to admission, and required endoscopic surgical control of bleeding more often, in comparison with anticoagulants (2.23 vs. 1.44, P < .05 and 23% vs. 6%, respectively, P < .05). Among anticoagulants, combined therapy (cauterization and packing) was required more frequently in the apixaban group compared to the rivaroxaban and warfarin groups (64% vs. 25% and 33%, respectively, P < .05). The rate of readmissions due to epistaxis, within 1 year of follow-up was lower in the factor Xa inhibitor groups compared with the warfarin and antiplatelet groups (16% vs. 9% and 4%, respectively, P < .05). Cessation of factor Xa inhibitor therapy was effective and uneventful with no further epistaxis events., Conclusions: Epistaxis under factor Xa inhibitors was effectively treated with no worse and perhaps even a better outcome when compared to other anticlotting medications., Level of Evidence: 4 Laryngoscope, 129:119-123, 2019., (© 2018 The American Laryngological, Rhinological and Otological Society, Inc.)

- Abstract
Objective: The thyroid cartilage (TC) in men has a more prominent thyroid notch and a narrower interlaminae angle (ILA) as compared with women. Anatomy textbooks classically stipulate that the ILA is 90° in men and 120° in women. Our observation, based on thyroid chondroplasty operations, of a much narrower angle led to the current investigation., Study Design: Cohort imaging study., Setting: Tertiary academic referral center., Subjects and Methods: Computed tomography angiography neck images of adult patients were studied. The ILA was measured on 2 axial planes: at the level of the vocal processes (and the upper portion of thyroarytenoid muscles) and 5 mm superior and parallel to the former. The anterior projection of the TC and the vertical dimensions of the midline cricothyroid membrane (CTM) were also measured., Results: A total of 126 patients were included in the study. The average ILAs were 63.5°±20.6° and 93.3°±16.6° for men and women, respectively (P < 10(-14)), and were significantly narrower at the upper level in comparison with the vocal process level (P < 10(-7) for men, P = .004 for women). The anterior projection of the TC in men was more prominent as compared with women (P = .0003) and significantly correlated with the ILA (P = .0159). The length of the midline CTM was 11.1±2.3 mm in men and 10.3±1.7 mm in women (P = .0355)., Conclusions: The ILA is narrower than that reported in the classic anatomy textbooks. In male patients, the upper part of the TC becomes narrower and projects anteriorly like a "jug's spout." The mean vertical dimension of the midline CTM was 10 to 11 mm., (© American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.)

- Abstract
Conclusions: In patients with total sudden sensorineural hearing loss (SSNHL), oral prednisone (OP) alone or intratympanic dexamethasone (ITD) alone have comparable results. The addition of salvage ITD following OP does not seem to add over either single modality treatment., Objectives: To study the effect of steroid-based treatments in patients with total SSNHL., Methods: The medical charts of 59 patients with total loss of hearing, defined as pure tone thresholds in the profound range (> 90 dB) with an unobtainable speech reception threshold (SRT) that were treated with OP (n = 20), ITD (n = 13), or OP followed by salvage ITD (n = 26) were analyzed. Response to treatment was evaluated by means of pure tone thresholds, SRT, and speech discrimination score (SDS), immediately after treatment and on a follow-up visit., Results: Forty-nine patients (83%) responded to treatment, with mean significant improvements of 36, 34, 31, and 25 dB at 500, 1000, 2000, and 4000 Hz, respectively. The mean improvement in SRT was 33 dB, and SDS improved by 32%. There were no differences in improvement in pure tone thresholds and SRT among the three treatment groups. The late effect of OP was similar to the effect of salvage ITD.

- Abstract
The aim of this study was to analyze prognostic factors of successful tracheal and cricotracheal segmental resection (TR/CTR), the type of revisions performed in cases of failure, and the outcome of revisions. The study is designed as case series with chart review. Between 1995 and 2011, 122 adult patients underwent TR/CTR. Forty-six patients (38 %) had concomitant airway pathologies and 59 patients (48 %) failed previous interventions. Forty-six patients (38 %) were aphonic with a complete obstruction. Cricotracheal, tracheotracheal, and thyrotracheal anastomosis was performed in 78 (64 %), 24 (20 %) and 20 (16 %) patients, respectively. Subglottic involvement, higher grade of obstruction, preoperative tracheostomy, presence of any concomitant airway pathology and impaired vocal cord movement were all associated with poorer outcome. Initially, 85 patients (68 %) achieved primary goal with no need for further intervention. Thirty-six patients underwent one or more revision surgeries (laser, dilatation, tracheostomy, stent or T-tube, laryngoplasty, segmental resection, posterior cordotomy) with a success rate of 69 %. Overall success rate, after revisions, was 88.5 %. Segmental tracheal resection for tracheal stenosis is highly successful in non-tracheotomized, cricoid sparing incomplete tracheal stenosis patients, without secondary airway pathologies. Initial failures of TR/CTR can be managed with revision surgery.

- Abstract
Background: Tracheostomy is a frequent, and at times semiurgent, surgical procedure. It is performed in close proximity to the thyroid gland, and in many cases requires division of its isthmus, putting a patient in danger of significant bleeding., Objectives: To examine prospectively the feasibility of vessel sealing in tracheostomy., Methods: A vessel-seating device was used in 24 consecutive patients undergoing tracheostomy. There were no exclusion criteria for enrolling the patients. No other hemostatic technique was used for dividing the isthmus., Results: There were no bleeding events throughout the postoperative period. The operating time saving was 5-10 minutes., Conclusions: Use of the vessel sealer was found to be straightforward, efficacious, rapid and safe.
