Monthly Variation in Bell's Palsy Based on Population Data of Korea.

Introduction: Several studies have reported that the number of patients with Bell's palsy varied significantly by month and season. However, few studies have reported the monthly variation in Bell's palsy based on the whole population. We investigated the monthly variation in Bell's palsy in Korea during a long-term period based on whole population data.

Positional changes in the uvula tip after adenotonsillectomy in children: preliminary result.

Background: Adenotonsillectomy has become the primary treatment for children with sleep-disordered breathing or obstructive sleep apnea. However, few studies have investigated positional changes in the soft palate or uvula after adenotonsillectomy in children. The present study aimed to evaluate positional changes in the uvula tip using cephalometric analyses after adenotonsillectomy in children.

Postoperative results of ventilation tube insertion: a retrospective multicenter study for suggestion of grading system of otitis media with effusion.

Background: In otitis media with effusion (OME), it is important to know when to surgically intervene and when careful monitoring is more appropriate. This study aimed to visualize and classify the clinical manifestations of OME and the correlation between the new grading system and postoperative results after ventilation tube insertion (VTI).

Methods: We classified the collective 1,012 ears from 506 patients into six groups: grade 0 (no effusion), grade I (scant effusion, but abnormal), grade II (effusion less than half of the tympanic cavity), grade III (effusion over half of the tympanic cavity, with air bubbles), grade IV (complete effusion), and grade V (retracted tympanic membrane or hemotympanum without air bubbles).

Changes of Temporal Processing and Hearing in Noise after Use of a Monoaural Hearing Aid in Patients with Sensorineural Hearing Loss: A Preliminary Study.

Background And Objectives: The relationship between hearing aid (HA) use and improvement in cognitive function is not fully known. This study aimed to determine whether HAs could recover temporal resolution or hearing in noise functions. Materials and.

Is the cochleovestibular nerve function affected in patients with hemifacial spasm?

Hemifacial spasm (HFS) is a motor disorder caused by the vascular compression of the facial nerve in the posterior fossa. The cochleovestibular nerve is close to the facial nerve and shares the same entry to the periphery, also has disorders caused by vascular compression. We evaluated the cochleovestibular nerve function in patients with HFS based on the hypothesis that vascular compression, which causes HFS, can also affect the nearby cochleovestibular nerve function.

One-stage cochlear implantation in patients with chronic otitis media using canal wall up mastoidectomy.

Background: Cochlear implantation (CI) with subtotal petrosectomy was recommended to avoid the complications for patients with chronic otitis media (COM).

Musical Hallucination Caused by Ceftazidime in a Woman with a Hearing Impairment.

Musical hallucinations remain a poorly understood clinical phenomenon, possibly because these types of hallucination have multiple causes and are rarely the focus of published reports. Here, the case of a 51-year-old female patient with a hearing impairment who developed musical hallucinations during treatment with ceftazidime, a third-generation cephalosporin, is presented. She responded to the discontinuation of ceftazidime and the initiation of low-dose olanzapine treatment.

Comparison of clinical outcomes between butterfly inlay cartilage tympanoplasty and conventional underlay cartilage tympanoplasty.

Objective: To assess the efficacy of butterfly inlay cartilage tympanoplasty and compare it with conventional underlay cartilage tympanoplasty in terms of success rate and hearing outcomes.

Materials And Methods: The study included 35 patients (36 ears) who underwent butterfly inlay cartilage tympanoplasty (inlay group, 23 ears of 22 patients) or conventional underlay cartilage tympanoplasty (underlay group, 13 ears). The anatomical success rate and hearing outcomes were analysed.

Risk factors for persistent otitis media with effusion in children: a case-control study.

Background: Otitis media with effusion (OME) is defined as middle ear effusion without acute signs of infection. OME usually resolves spontaneously; however, persistent OME may require the insertion of a ventilation tube. This study investigated risk factors for persistent OME in children who undergo ventilation tube insertion.

Clinical Characteristics of Patients with Dizziness after Motor Vehicle Accident.

Objective: The purpose of this study was to identify the clinical characteristics of dizziness occurring after a motor vehicle accident.

Materials And Methods: We retrospectively analyzed 217 patients who had visited a tertiary medical center complaining of dizziness after a motor vehicle accident between January 2009 and December 2014. Of the 217 patients, we enrolled 54 patients who had undergone a vestibular function test and had no definite evidence of fracture of the temporal bone or intracranial lesions.

Percutaneous Drainage and Povidone-Iodine Sclerotherapy of Cervical Lymphatic Malformation.

Lymphatic malformations in cases with macrocystic lesions can be treated with surgical excision or sclerotherapy using alcohol, bleomycin, doxycycline, or OK-432. We report a case of a 24-year-old woman who underwent percutaneous drainage and povidone-iodine sclerotherapy as primary treatment for cervical lymphatic malformation. The patient underwent povidone-iodine sclerotherapy for 3 consecutive days.

Image-guided nasal endoscopic drainage of an orbital superior subperiosteal abscess.

A 48-year-old woman presented to the emergency department with swelling and erythema of the right upper eyelid for 4 days. Computed tomography showed a superiorly-based subperiosteal orbital abscess together with paranasal sinusitis. She was managed medically, but symptoms did not improve, so we drained the abscess using image-guided intranasal endoscopy.

Pseudoaneurysm of the Petrosal Internal Carotid Artery in the Middle Ear as a Complication of Middle Ear Cholesteatoma.

We report the case of a 66-year-old man who had significant otorrhagia caused by a ruptured pseudoaneurysm in the petrous internal carotid artery (ICA). The patient had middle ear cholesteatoma, and computed tomography (CT) showed bony erosion and exposure of the ICA into the middle ear cavity.

Influence of middle ear mucosal condition on post-tympanoplasty audiologic outcome.

In this study, the association between the middle ear mucosal condition and post-tympanoplasty audiologic outcome was investigated in patients with chronic otitis media without cholesteatoma. One hundred and forty-three patients with chronic otitis media were collected in the Department of Otorhinolaryngology-Head and Neck Surgery at Asan Medical Center between January, 2009 and December, 2011. In the course of tympanoplasty, the status of the middle ear mucosa was divided into normal or abnormal by one surgeon.
