Background and Objectives The evaluation of subjective outcomes of hearing aid fitting is of paramount importance along with audiometric improvement. The aim of this study was to develop a Korean adaptation of the International Outcome Inventory for Hearing Aids (IOI-HA) and to determine its reliability and validity. Subjects and Method The translation of IOI-HA into the Korean version (K-IOI-HA) was completed through a process of forward translation, reconciliation, reverse translation and cognitive debriefing. K-IOI-HA was administered to 101 patients using hearing aids and visiting any the 10 referral hospitals. Reliability was evaluated by Cronbach’s alpha coefficient and by test-retest analysis. Validity was assessed by confirmatory factor analysis and criterion validity based on the results of pure tone audiometry. Results K-IOI-HA showed a good internal consistency (Cronbach’s α=0.83) and a high test-retest reliability (r=0.943, p<0.01). Validity checked by confirmatory factor analysis also show-ed good construct validity. Conclusion The Korean version of IOI-HA is a reliable and valid tool for evaluating subjective outcomes of hearing aids.

Background and Objectives:Acute epiglotitis is a disease that may become serious or even fatal because of sudden upper airway obstruction. The incidence of acute epiglottitis in children has declined with introduction of the Haemophilus influenza type b vacine. However, there have ben few reports about acute epiglottitis in adults up until now. The aim of this study was to ases clinical characteristics of adult cases of acute epiglottitis. Subjects and Method:We retrospectively reviewed 85 hospi-talized adult patients who had been admited to the Department of Otolaryngology-Head and Neck surgery, Korea University Hospital from January 1998 to December 2002, and diagnosed with acute epiglottitis. Results:(27% ) and 24 cases (28% ) were found in fourth and sixth decades of age, respectively. The male-to-female ratio was 1.6:1. Monthly distribution showed that 12 cases (14% ) were in March and 11 (13% ) in July. The most common symptom was in the order of throat pain (78% ). Others were dysphagia (68% ), voice change (67% ) and dyspnea (42% )with antibiotics and steroids. About a half of all cases (54% ) were hospitalized for 4 to 5 days. Tracheostomy was performed in 2 patients and orotracheal intubation in one patient. Conclusion:Throat pain and dysphagia were most common symptoms of acute epiglottitis. In most cases, therapies using intravenous antibiotics and short-term steroid were efective, but otolaryngologist obstruction in only three cases during the first wek of hospitalization.

Primary adenoid cystic carcioma of trachea is rare, with an incidence of only 0.2 per 100,000 persons per year. When all series of the tracheal carcinomas are combined, adenoid cystic carcinoma is the second most common tumor only to squamous cell carcinoma in incidence. Most patients have wheezing or stridor, dyspnea, hemoptysis, and cough as symptoms. Treatment options include surgery alone, radiation therapy alone, or a combination of both. The recommended surgical option is primary tracheal resection and reconstruction. Recently, we experienced a case of adenoid cystic carcinoma in 45 year old female patient who was treated tracheal tumor resection and end-to-end anastomosis of the trachea, so we report this case with the literatures.

Benign lymphoepithelial cysts of parotid gland were first described by Miculicz in 1888, have been presented for a long time, uncommonly. But, recently it has been reported with increasing frequency since the onset of human immunodeficiency virus (HIV) infection. Benign lymphoepithelial cysts can be diagnosed by the fine needle aspiration in conjunction with the history and physical examination. The therapeutic options of benign lymphoepithelial cysts have been limited to aspiration, surgical resection, medical therapy, radiotherapy and sclerotherapy. Recently, we experienced a case of benign lymphoepithelial cyst of right parotid gland, so we report this case with review of the literatures.

Aims of this study are 1) to evaluate radiological characteristics of the anterior inferior cerebellar artery (AICA) using three-dimensional Fourier Transformation Constructive Interference in Steady State (3D-FT CISS) MR imaging, and 2) to investigate the relationship between types of AICA and auditory or vestibular symptom. Materials and Methods:This is a retrospective study. Forty-five adult patients, who presented with auditory symptom and/ or vestibular symptom of unknown etiology at an ENT hospital from April 2010 to August 2011, were studied. Using 3D-FT CISS images, AICA course was identified in all the patients (90 ears). The relationship was investigated between types of the AICA loop and vestibulocochlear symptom. Results:According to Chavda’s classification, 55 type I loops, 24 type II loops and11 type III loops of the AICA were observed. Only type III loops show a statistically significant association with ipsilateral hearing loss and tinnitus (p=0.0001). According to Shelton’s classification, 14 class A courses, 52 class B, 18 class C and 6 class D were observed. However, any sigificant relationship was not found between cochleovestublar symptoms and AICA types of class A through D. Conclusion:A significant relationship was found between AICA loop and auditory symptom, when it extends more than 50% of the length of IAC. In these patients, neurovascular compression of vestibulocochlear nerve could be considered as a possible cause of hearing deterioration and tinnitus.

장기간의 비보상성 전정기능저하를 보이는 제8뇌신경의 신경-혈관 교차압박 증례보고

The neurovascular cross-compression (NVCC) of the eighth cranial nerve (CN) is a clinical entity with symptoms of recurrent vertigo or tinnitus. Although the diagnostic criteria have been defined, the precise clinical presentation and pathomechanism have not been clarified. The treatment response to the carbamazepine; drug of choice for first line medical treatment, has been considered as one of the diagnostic criteria. Herein, we present a case of chronic uncompensated unilateral vestibular hypofunction who responded dramatically to carbamazepine medication. A 55 year-old male admitted to the hospital with symptoms of recurrent oscillopsia and headache for more than 7 years. His symptoms were aggravated by positional changes. Vestibular function tests showed spontaneous nystagmus, canal paresis on caloric test and vestibular dysfunction on dynamic posturography, which represented unilateral uncompensated vestibular hypofunction. Although his symptom was not relived by vestibular rehabilitation, he was treated with carbamazepine. A long standing uncompensated unilateral vestibular hypofunction without any auditory symptoms could be one of the clinical presentations in NVCC of the eighth CN.

Background and Objectives:Asesment of the upper airway for possible site of obstruction is one of the keys to a succesful normal standard data was prerequisite for using this equipment. The aim of this study was to measure normal standard data in normal adults with acoustic pharyngometry on siting, supine, left and right decubitus positions. Subjects and Method:A total number of 120 normal adults were examined by acoustic pharyngometry. Results:Oropharyngeal junctional area was located within 8- 1 cm, and glotic area was within 15- 18 cm. There was no statistically significant diference in pharyngeal crosssectional area and pharyngeal volumes measured on siting, supine, left and right decubitus positions (p>0.05). Conclusion:Acoustic pharyngometry is easy, rapid and cost-efective and has been shown to be successfully repeatable.

Craniometaphyseal dysplasia is a rare bone disorder of unknown etiology characterized by overgrowth of the craniofacial bones and abnormal remodeling of the metaphyses. This disease can be sporadic or transmitted by autosomal dominant and recesive ng, hypertelorism, extremely broad and flat nasal bridge with a saddle deformity, lacrimal duct obstruction, paranasal sinus and mastoid obliteration, compresion of cranial nerves, with resultant loss of vision, strabismus, facial paralysis, and deafness. Also, abnormal bone remodeling results in widening in the metaphyses of the long tubular bones, giving the appearance of an Erlenmeyer flask. We present a sporadic case of craniometaphyseal dysplasia associated with the facial paralysis observed in a 4 year-old emphasizing the importance of early detection of accompanying lesions for proper management.
