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

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.

ObjectiveTo investigate hearing and the take rate of crushed cartilage grafts in tympanoplasty.MethodsIn this double-blinded, randomised, controlled trial, 46 patients with tympanic membrane perforation were enrolled. A conchal cartilage graft was used for reconstruction in both intervention and control groups. In the intervention group, crushed cartilage was used. The success rate and hearing results were ascertained every four months over a one-year follow-up period.ResultsA total of 36 patients – 20 in the intervention group and 16 in the control group – completed one year of follow up. There were no statistically significant differences between the two groups in mean air–bone gap, bone conduction threshold, speech discrimination score or speech reception threshold.ConclusionThe reduction in living cells after crushed cartilage tympanoplasty may decrease the rigidity and the volume of the graft, but may not necessarily improve the hearing results.

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.
