BackgroundTinnitus is a common condition and frequently can be annoying to affected individuals. We investigated the prevalence and associated factors for tinnitus in South Korea using the data from the Korea National Health and Nutrition Examination Surveys (KNHANES) during 2009–2011.MethodsKNHANES is a cross-sectional survey of the civilian, non-institutionalized population of South Korea (n = 21 893). A field survey team that included an otolaryngologist moved with a mobile examination unit and performed interviews and physical examinations.ResultsAmong the population over 12 years of age, the prevalence of any tinnitus was 19.7% (95% CI 18.8%–20.6%). Tinnitus was more prevalent in women, and the prevalence rate increased with age (P < 0.001). Among those with any tinnitus, 29.3% (95% CI 27.3%–31.3%) experienced annoying tinnitus that affected daily life. Annoying tinnitus also increased with age (P < 0.001), but no sex difference was demonstrated (P = 0.25). In participants aged 40 years or older, age, quality of life, depressive mood, hearing loss, feeling of dizziness, and rhinitis were associated with any tinnitus (P < 0.05). Age, hearing loss, history of cardiovascular disease, and stress were associated with annoying tinnitus (P < 0.05).ConclusionsTinnitus is a common condition, and a large population suffers from annoying tinnitus in South Korea. Public understanding of associated factors might contribute to better management of tinnitus.

Three different treatment protocols (oral steroid, ITDI, or the combination) resulted in similar hearing recovery rates. Therefore, OPD-based systemic and/or local steroid therapy can be recommended as an initial treatment in ISSNHL.

The effect of intratympanic steroid injection is controversial as salvage or initial treatment option for sudden sensorineural hearing loss (SSNHL) and almost unknown if it is consecutively to use after initial systemic steroids. This study aimed to analyze the efficiency of intratympanic dexamethasone injection (ITDI) as a sequential treatment in the patients who failed initial systemic steroid treatments for SSNHL. Forty-six patients with SSNHL who did not respond to initial systemic steroids were prospectively included in the study. The patients were randomly classified into two groups; the ITDI group (21 patients) did not take four sequential ITDI within 2 weeks after systemic steroids, and the control group (25 patients) took any more medications. Hearing improvement was defined as a 10 dB or more decrease in the pure tone average (PTA) of the four-frequencies (0.5, 1, 2, and 3 kHz). Hearing improvement was observed in 10 (47.6%) of 21 ITDI patients and in 4 (16.0%) of 25 control patients (P = 0.027). An improvement of the mean PTA was 11.4 dB in the ITDI group and 1.7 dB in the control group (P = 0.004). The ITDI group showed significant hearing improvement at low frequency (500 Hz) than the control group. The patients with 70 or more dB in PTA before ITDI showed significant hearing improvement than the other patients with better PTAs (P = 0.038). The sequential ITDI, which is performed immediately after initial systemic steroid therapy, may be a simple, effective second-line treatment of choice for the patients who show poor response to initial treatments for SSNHL.

Objective: Preauricular sinuses (PAS) are common congenital malformations that usually occur at the anterior margin of the ascending limb of the helix, but the positions of PAS and directions on the fistular tracts are rarely posterior to the external auditory canal (EAC), which presents as a postauricular swelling. We named these cases as the variant type of PAS ('postauricular sinuses'), and compared their clinical manifestations with those of the classical type.Study Design: A retrospective study. Methods:We retrospectively reviewed the charts of patients who had undergone preauricular fistulectomy from 2002 to 2006. These patients were then categorized into two groups according to the position of the preauricular sinus sac. The classical group was defined as the group of patients with sacs located on the (superior) anterior to the EAC, and the variant group as those whose sacs are located on the posterior site of the EAC. We analyzed the incidence, previous histories, clinical manifestations, recurrence rates, and surgical techniques of the variant type of preauricular sinuses and compared them with those of the classical type.Results: Eleven (10.9%) of 101 patients were diagnosed with preauricular sinuses of the variant type. The male to female ratios of the classical and the variant groups were 44:46 and 7:4, respectively. The average age of the patients was approximately 11 to 13 years in both groups. All variant types of preauricular sinuses showed preauricular pits located posterior to the imaginary line that connects the tragus with the posterior margin of the ascending limb of the helix, unlike the classical type. Most (72.8%) of the fistular tracts of the variant type were directed in the posterior-middle direction from the pits. The variant types were operated with a dual approach using preauricular and retroauricular incisions, unlike the classical type, and the recurrence rate was 0% (compared with 2.2% in the classical type).Conclusion: Frequent postauricular infected swellings may indicate the presence of the variant type of preauricular sinuses. The variant type of preauricular sinuses presenting in the postauricular area were found to have an unusual location of the fistula pit that was positioned posterior to the imaginary tragal extended line. A comprehensive physical examination of the preauricular pits should be performed to avoid incomplete excision of the variant types.

To measure the effect of septoplasty on the volume of inferior turbinate in patients with a deviated nasal septum. Design: In this retrospective analysis, patients who underwent septoplasty without turbinate surgery from May 1, 2003, through April 30, 2006, were studied. The thicknesses and cross-sectional areas of mucosa and conchal bones were measured with computed tomography before the operations and at least 1 year after the operations. Setting: University hospital. Patients: A total of 20 patients who presented with a chief concern of nasal obstruction. Main Outcome Measures: The thicknesses of the medial mucosa, bone, and lateral mucosa and the cross-sectional area of turbinate before and after septoplasty were compared using the Wilcoxon signed rank test. P Ͻ.05 was considered statistically significant. Results: The medial mucosa and cross-sectional area of the inferior turbinate on the concave side of the septum were significantly decreased by septoplasty (both, P=.01), and the medial mucosa and cross-sectional area of the inferior turbinate on the convex side of the septum were significantly increased by septoplasty (P=.01). The thicknesses and cross-sectional areas of the conchal bone on the concave and convex sides of the septum were not affected by septoplasty. Conclusion: After septoplasty, inferior turbinate hypertrophy, especially in the medial mucosa, may reverse.

Recurrent and persistent BPPV are not rare diseases and occur with a higher incidence than expected, especially in patients with secondary causes. However, they can be successfully treated with frequently repeated CRPs.

Objectives/Hypothesis: Horizontal semicircular canal (HSC) benign paroxysmal positional vertigo (BPPV) has been reported to have a poorer prognosis than posterior semicircular canal BPPV. Incorrect determination of the affected ear appears to be one of the causes of poorer outcome. The aim of this study was to assess the efficacy of the ''bow and lean test'' (BLT) for proper determination of the affected ear followed by preferable treatment outcomes of HSC-BPPV.Study Design: A prospective study. Results: The remission rates after two sessions of CRPs in the BLT group and the HRT group were 83.1% and 67.4% (P ¼ .041), respectively, for the canalolithiasis type and 74.7% and 61.1% (P ¼ .250), respectively, for the cupulolithiasis type. In the BLT group, 76.8% had bowing and/or leaning nystagmus; 35.7% of them (45 of 126 cases) benefited from BLT with regard to determining the affected ears because HRT was unable to provide the definitive affected ears (17 cases) or showed different localization between two methods (28 cases).Conclusions: BLT is a useful method to improve the remission rates of HSC-BPPV, giving more corrective information regarding affected ears than the HRT alone.
