Introduction: Idiopathic Sudden Sensorineural Hearing Loss as a subset of sensorineural hearing loss will be confirmed by a progressive hearing loss of at least 30 dB at three contiguous frequencies over 72 hours or less. A sudden or abrupt hearing loss correlates with the time course, and a vascular event is presumptive aetiology. There is an inverse association between Omega-3 consumption and hearing loss. This study aimed to evaluate the efficacy of Omega-3 adjunctive therapy in Idiopathic Sudden Sensorineural Hearing Loss by audiometric assessments., Materials and Methods: In this randomised, triple-blind, placebo-controlled trial, all participants aged 18-70 with a history of sudden deafness (within 12 hours and ≤ 30 days) were eligible for enrollment. They were included if audiology diagnostic tests confirmed the SSNHL. Ultimately, they were randomised to the Omega-3 group and the placebo group., Results: Thirty-three patients were randomly allocated to the Omega-3 group and thirty-two to the placebo group. Vertigo (32.3% of all patients) and underlying conditions had significant relationships with complete response (C.R.)-final hearing level ≤of 25 dB in pure-tone average (P < 0.05). There was no significant difference between both groups before and after treatment. Although it was not statistically significant, patients in the Omega-3 group had faster recovery than placebo., Conclusions: Omega-3 adjunctive therapy did not have a therapeutic effect on SSNHL patients. Moreover, C.R. happened in half the patients. Vertigo and underlying conditions considerably worsen the recovery from SSNHL.

Background: Emergence agitation (EA) is an important clinical problem that occurs during the initial period of recovery from anesthesia. This study aimed to determine the effects of ketamine and lidocaine administered on agitation level, postoperative pain, and hemodynamic changes in adults after rhinoplasty., Materials and Methods: Totally 72 patients scheduled to undergo elective rhinoplasty were enrolled in this prospective study. Patients were randomly divided into three groups including control group ( n = 24), ketamine group ( n = 24), and lidocaine group ( n = 24). Twenty minutes before surgery completion, 1 ml saline was administered intravenously to the saline group, while 0.5 mg/kg ketamine or 1.5 mg/kg lidocaine was administered to two other groups. The emergence agitation level of the patients was evaluated using the Richmond Agitation-Sedation Scale just after extubation and in the post-anesthesia care unit (PACU). Postoperative pain was evaluated by Numerical Rating Scale that scored (from 0 to 10) every 10 min until the patients were discharged from PACU., Results: There was a significant difference between EA level between ketamine ( P = 0.049) and lidocaine ( P = 0.019) groups compared to the control group, and there was a significant difference between pain level between the ketamine ( P = 0.008) and lidocaine ( P = 0.035) groups compared the to control group, while there was no significant difference between the level of agitation ( P = 0.922) and level of pain ( P = 0.845) after extubation between the ketamine and lidocaine groups., Conclusion: Ketamine and lidocaine are highly effective in preventing EA and pain control. Further studies with a greater sample size and longer follow-up period are needed to confirm the current findings., Competing Interests: There is no conflict of interest., (Copyright: © 2023 Journal of Cutaneous and Aesthetic Surgery.)

Objective: To analyze the Reflux Symptom Index (RSI) and the Voice-Related Quality of Life (V-RQOL) scores based on the perceptual and analytical parameters in primary MTD patients with no reflux., Study Design: Cross-sectional study., Methods: One hundred and eighteen participants, that is, sixty patients with normal voices and fifty-eight patients with primary MTD were recruited in this study. The diagnosis of primary MTD was made by perceptual voice analysis, neck palpation, video-laryngoscopic examination, and exclusion of other etiologies. Acoustic analysis and the GRBAS (Grade, Roughness, Breathiness, Asthenia, and Strain) scale were evaluated for all participants. The V-RQOL and RSI questionnaires were then given to all participants., Results: This study included 118 participants of 29 males (48.3%) and 31 females (51.7%) in the normal group. MTD group also included 27 males (46.6%) and 31 (53.4%) female patients. Mean (SD) RSI and V-RQOL scores were 12.35 (3.84) and 11.09 (2.20) for the normal group, and 22.87 (6.97) and 22.89 (7.94) for the MTD group (P = .000). In the MTD group, V-RQOL had a positive correlation with jitter for /i/ and /u/, Noise to Harmonic Ratio (NHR) for /i/, /a/, and /u/, and Grade, Roughness, and Strain of GRBAS scale (P < .05). In addition, RSI had a positive correlation with Strain in the MTD group (P < .05)., Conclusion: MTD patients in the absence of laryngopharyngeal reflux findings may have high RSI scores. Hence, patients with high RSI scores and disproportionate acoustic and perceptual analysis would require a thorough evaluation of MTD., Level of Evidence: 4 Laryngoscope, 131:E1573-E1579, 2021., (© 2020 American Laryngological, Rhinological and Otological Society Inc, "The Triological Society" and American Laryngological Association (ALA).)

Background: Many patients with coronavirus disease 2019 (COVID-19) complain from olfactory dysfunction (OD). Aims/objectives: To evaluate the prevalence, prognosis, and recovery from OD in COVID-19 patients., Material and Methods: In this study, patients with COVID-19 symptoms who were referred to six different tertiary referral centres were recruited after positive results for COVID-19. All patients were assessed for a one-month follow-up after the initial diagnosis of COVID-19., Results: Three hundred and eleven patients with COVID-19 were recruited in the present study. Two hundred and seven patients (66.6%) had a recent history of OD. One hundred and seventy-eight patients had experienced OD as a primary symptom intercurrent to other COVID-19 symptoms or solely. Sixty-nine patients had OD at the time of presentation to referral centres. Headache and nasal obstruction had significant relationships with recovery from OD in this subgroup, and the platelet count was the most important predictor for the recovery from OD. One hundred seventy-nine (86.4%) patients were nearly or fully recovered from OD approximately a month after the onset of OD., Conclusion: Headache, nasal obstruction, and platelet count may have specific roles as prognostic factors in the recovery from OD.

Introduction: The categorization of delayed endolymphatic hydrops (DEH) based on the ear which produces vertigo may sometimes cause misdiagnosis., Objectives: The aim of this study was investigating the vestibular-evoked myogenic potentials (VEMPs), electrocochleography (ECoG), and videonystagmography (VNG) in cases with DEH to determine the ear that originates symptoms., Methods: In this cross-sectional study, 34 patients - 20 males and 14 females - with profound unilateral sensorineural deafness and vertigo attacks were recruited and evaluated by the ECoG, VNG, and VEMPs tests., Results: The average age was around 43; the summating potential/action potential was abnormal in 29.4% of patients in their normal auditive ear. In 32.4, 17.6, and 50% of cases with a deaf ear, absent, normal, and abnormal VEMPs results were sequentially observed, respectively. In normal-hearing ears, absent, normal, and abnormal VEMPs were observed in 23.5, 50, and 26.5%, respectively. In the normal-hearing ear, the distribution of abnormal VEMPs was 26.5%, and in the deaf ear, this parameter was abnormal in 50% of the opposite ear (p value = 0.00021). In the VNG test, among patients with a normal-hearing ear, results in 27 and 7 patients were sequentially normal and hypofunction., Conclusion and Significance: The probability of a hypofunction VNG test in a normal-hearing ear might be greater when the VEMPs results of the contralateral deaf ear are normal. In patients with a normal-hearing ear, the distribution of abnormal VEMPs in the contralateral deaf ear is greater, although the intact side may also manifest abnormality in VEMPs tests. The initial evaluation should begin in a deaf ear as well as for the normal-hearing ear ere utilizing ablation surgery., (© 2021 S. Karger AG, Basel.)

Objectives: Usefulness of preoperative tissue sampling and pathology diagnoses in parotid gland tumors were accepted worldwide. We investigate the role of CNB in the parotid gland lesions when FNA results are inconclusive., Methods: We conducted a cross sectional study to evaluate CNB results from fifty-two patients with history of parotid gland lesion and inconclusive previous fine needle aspiration., Results: In this study, 45 out of 52 CNB results determined definite histological subtype diagnosis. Four CNB reports were inconclusive and three CNB results were compatible with malignancies, but did not define definite diagnosis. Calculated sensitivity for diagnosis of malignancy was 96% and specificity was 85%. Negative predictive value, positive predictive value, and accuracy for CNB in detecting malignancy, were calculated 94%, 90%, and 92%, respectively., Conclusions: When FNA is not conclusive, CNB may be used as a precise method to evaluate the parotid gland lesions., (Copyright © 2020 Elsevier Inc.

Introduction  The most common site of salivary gland tumors is the parotid gland. Computed tomography (CT), magnetic resonance imaging (MRI), and sonography are imaging modalities to differentiate benign from malignant parotid tumors. Objective  The aim of this study is the evaluation of the diagnostic value of perfusion CT for differentiating histological categorization of benign and malignant parotid tumors. Methods  A total of 29 patients with parotid neoplasms were enrolled in this study. Mean age and all CT perfusion variables (gradient and permeability, blood flow [BF], blood volume [BV], mean transit time [MTT], permeability surface [PS], maximum intensity projection [MIP], time-density curve [TDC], and time to peak [TTP]) were compared among three groups (malignant tumors [MTs], Warthin's tumor [WT] and pleomorphic adenomas [PA]). Results  The mean age of the patients was 55.9 ± 14.1 (26-77), and 15 of them were male (51.7%). Eleven lesions were PAs [37.9%], 8 lesions were WTs (27.6%0 and 10 lesions (34.5%) were MTs (6 acinic cell carcinomas [ACCs], 3 adenocystic carcinomas [AdCCs], and 1 mucoepidermoid carcinoma [MEC]). The mean age of the patients with WTs was 62 ± 7.5 years; 52 ± 14.2 for patients with Pas, and 55.2 ± 17.2 for those with MTs ( p  = 0.32). The mean MIP was 122.7 ± 12.2 in WT, while it was 80.5 ± 19.5 in PA, and 76.2 ± 27.1 in MTs ( p  < 0.001); The mean MIP for WT was higher than for PAs and MTs; the values of MTs and PAs were not statistically different. The average of BF, BV, and curve peak were higher in WTs in comparison with the other two groups, and curve time 2 and TTP were higher in PAs in comparison with MTs. Conclusion  Based on this study, perfusion CT of the parotid gland and its parameters can distinguish between benign and malignant parotid masses., Competing Interests: Conflicts of Interest The authors have no conflicts of interest to declare.
