Intratympanic corticosteroid injection as a first-line treatment of the patients with idiopathic sudden sensorineural hearing loss compared to systemic steroid: A systematic review and meta-analysis.

OBJECTIVES: The current study aimed to investigate if there is a difference in the use of intratympanic steroid therapy (IST), compared to systemic steroid treatment (SST), as an initial treatment for patients with sudden sensorineural hearing loss (SSNHL) by a meta-analysis design performed on the mean pure-tone average (PTA) improvement and the complete recovery rate. METHODS: A systematic literature review was performed on randomized controlled trials published from 1990 to August 2020 in some databases including PubMed/MEDLINE, Scopus, Embase, Web of Science, Cochrane library/CENTRAL, Ovid, ProQuest, Google Scholar, and clinical trials.gov. The primary outcomes of interest were pure-tone average improvement and complete recovery rates. RESULTS: Six eligible studies with 496 patients (250 patients in the IST group and 246 subjects in the SST group) were included in this study. The pooled standardized mean difference of the PTAs was estimated as 0.07 (95% CI = -0.10 to 0.25; I2 = 0.0%, P = 0.668), and the pooled odds ratio of complete recovery rate was obtained as 1.00 (95% CI = 0.66 to 0.151; I2 = 31.6, P = 0.199). Moreover, the pooled standardized mean difference of pure-tone average for the intratympanic steroid treatment group compared to the patients with oral steroid treatment was 0.07 (95% CI = -0.12 to 0.26; I2 = 0.0%, P = 0.526). CONCLUSIONS: The current study demonstrated that the effect of intratympanic injection of corticosteroid, as a first-line treatment, is not statistically different from the systemic route in improving the hearing outcomes among patients with SSNHL.

A Comparison Between Two Methods of Face-Lift Surgery in Nine Cadavers: SMAS (Superficial Musculo-Aponeurotic System) Versus MACS (Minimal Access Cranial Suspension).

BACKGROUND: This study aimed to compare the average amounts of facial skin and muscle lifting in two different face-lift methods, superficial musculo-aponeurotic system (SMAS) plication and minimal access cranial suspension (MACS), to evaluate the effectiveness of each method in facial excursion. METHODS: Thirty-six face-lift surgeries were performed on nine cadavers between October and December 2010. Both SMAS and MACS surgeries were done on each side of the cadaver faces. The average amounts of skin and muscle lifting up and out in three defined anatomical landmarks were compared between the two methods, SMAS plication and MACS lift procedure. RESULTS: Nine fresh cadavers with the mean age of 53 ± 6.7 years entered the study. Seven (77.8 %) were males and two (22.2 %) were females. The average amounts of lifting of the anatomical landmarks up and out were significantly greater in the SMAS plication method compared to the MACS lift procedure (P values <0.05), whereas facial symmetry was not significantly different between the two methods. CONCLUSION: The overall amounts of facial skin and muscle lifting by the SMAS plication method were greater than the MACS lift procedure. However, it does not justify ignoring the benefits of the MACS lift procedure in terms of less invasiveness and quicker recovery.

Impact of Acamprosate on Chronic Tinnitus: A Randomized-Controlled Trial.

OBJECTIVES: Tinnitus is a common and distressing otologic symptom, with various probable pathophysiologic mechanisms, such as an imbalance between excitatory and inhibitory mechanisms. Acamprosate, generally used to treat alcoholism, is a glutaminergic antagonist and GABA agonist suggested for treating tinnitus. Thus, we aimed to evaluate the efficacy and safety of acamprosate in the treatment of tinnitus. METHODS: The current randomized-controlled trial study included 20 subjects with chronic tinnitus. After performing psycho-acoustic, psychometric and electrophysiological evaluations, all studied tinnitus subjects were randomly divided into two groups of acamprosate and placebo. The first group received oral acamprosate (two tablets of 333 mg/d, three times a day), whereas the second group was given placebo treatment (two tablets, three times a day). After the first 30 days, all evaluations were repeated for the studied groups just in the same manner before the study. Subsequently, the final results of each evaluation were compared together with the baseline values. RESULTS: Nine studied subjects randomly received acamprosate, whereas eleven others received a placebo. There was no significant improvement in the psycho-acoustic tests, except a decrease was observed in the pitch match of tinnitus (P = .039). For those subjects who were receiving acamprosate, a significant reduction was observed in tinnitus handicap inventory (P = .006), tinnitus questionnaire scores (P = .007), and the visual analog scores (P = .007) compared to the placebo group. There was a significant reduction in Action Potential latency (P = .048) as well as an increase in the amplitude of distortion product otoacoustic emissions at 4 kHz (P = .048). CONCLUSIONS: The study results indicated a subjective relief of tinnitus as well as some degree of the electrophysiological improvement at the level of the cochlear and the distal portion of the auditory nerve among the subjects who received the acamprosate.

Vitamin D Levels in Children with Adenotonsillar Hypertrophy and Otitis Media with Effusion.

INTRODUCTION: Vitamin D has been suggested to play a considerable role in the function of the immune system in various infectious, inflammatory, and autoimmune conditions. Otitis media with effusion (OME), defined as the presence of non-purulent fluid within the middle ear without signs or symptoms of suppurative otitis media, has a number of inflammatory predisposing factors. This study was designed to explore the association between vitamin D deficiency and OME. MATERIALS AND METHODS: In this cross-sectional study, 74 children aged 2-7 years with an obstructive indication for adenotonsillectomy were included. Patients were divided into two groups based on the need for ventilation tube insertion for OME. Thirty-two children were enrolled in the OME group and 42 in the control group. The mean vitamin D level was compared between the two groups. RESULTS: Mean vitamin D concentration in all patients was 11.96±5.85 ng/ml (9.79±4.36 ng/ml in the OME group and 13.61±6.33 ng/ml in the control group; P=0.003). There was also a significant difference in levels of vitamin D in patients referred in winter (9.0±2.94 ng/ml) compared with the summer (19.85±4.21 ng/ml; P=0.001). Data analyzed based on the season in which the patients were referred showed no significant difference between the OME and the control group. CONCLUSION: Although our results showed lower serum levels of vitamin D in OME patients, the difference was not significant when seasons were taken into consideration. Therefore, the season is an important confounding factor in any research related to vitamin D due to the effect of sun-induced vitamin D.

Chondroradionecrosis of the Larynx in a Patient with Laryngeal: A Case Report.

INTRODUCTION: Actinomycosis of the larynx has been rarely reported in the literature and usually occurs in patients with a history of laryngeal carcinoma and radiation therapy. However, its co-existence with chondroradionecrosis due to radiotherapy is even rarer. The most common site of infection is the cervicofacial region, especially in the submandibular area. CASE REPORT: Here we report a 63-year-old male with a history of chemoradiotherapy because of laryngeal cancer 1 year earlier who presented with laryngeal actinomycosis. After prolonged penicillin-based treatment, the patient underwent thyroid cartilage defect reconstructive surgery because of a laryngocutaneous fistula due to chondroradionecrosis. The diagnosis, work-up, and management of the case are discussed, as well as a review of the literature. CONCLUSION: Although actinomycotic infection of the larynx is rare, it should be considered in the differential diagnosis of laryngeal complaints, especially in immunocompromised patients.
