Background and Objectives:Many types of cartilage tympanoplasty have been used in various middle condi-tions effectively. The purpose of this study is to evaluate the efficacy of type III cartilage shield tympanoplasty. Subjects and Methods:We adopted a carvum conchal cartilage shield tympanoplasty for 3 cases of cholestea-toma, 6 adhesive otitis media, and 6 chronic otitis media of near-total perforation. Malleus handle was medialized but intact before surgery in all the 15 cases. For the hearing outcome evaluation, we set control group of conven-tional type III tympanoplasty with cartilage capping partial ossicular reconstruction using partial ossicular recon-struction prosthesis. Air-bone gap (ABG) was compared between the study group and control group before and after surgery, and postoperative neo-drum status and complication was evaluated. Results:None of the study ears showed reperforation or any complication at minimum 9 months of follow-up. Two cases were found to have an- terosuperior partial retraction of neo-drum. The average ABG was 27.2±9.4 dB preoperatively and 19.0±11.6 dB postoperatively in study group, and 39.58±18.92 dB preoperatively, 20.76±21.36 dB postoperatively in con-trol group. No statistical difference of ABG was found between study and control group (p>0.05). Conclusions:Cartilage shield type III tympanoplasty was safe and effective in high risk of failure group such as large perfora-tion, atelectasis, adhesive otitis media, and cholesteatoma with medialized malleus.
Acute ischemic stroke in the distribution of anterior inferior cerebellar artery (AICA) is known to be associated with vertigo,nystagmus, facial weakness and gait ataxia. A few reports have carefully examined the deafness associated with the AICAinfarction. A 55 year old man was presented with right sudden hearing loss, tinnitus and vertigo. The magnetic resonance imageof the brain with 4-vessel angiogram showed stenosis in the lower third of the basilar artery due to partial thrombosis and noremarkable lesion in AICA. Although heparin treatment was done, the patients hearing was not improved. After 3 months ofheparin treatment, the patient was presented again with left sudden hearing loss, tinnitus and facial palsy. The magnetic resonanceimage and angiogram showed increased size of thrombosis and non-visualization of left vertebral artery and basilar artery.Diffusion scan showed focal infarction involving the left AICA territory. Recently, we experienced a case of bilateral suddenhearing loss caused by the right AICA plus syndrome and the left AICA infarction. So authors report this case with a review ofliterature.
Intracranial lipomas are uncomon and rarely symptomatic benign tumors comprising 0.1% of intracranial tumors. Although e tumors. And lipomas within the cerebellopontine (C-P) angle and internal auditory canal are extremely rare. In the C-P angle region, lipomas are the most symptomatic compared in other intracranial regions, although symptoms depend on the origin site and involve neural and vascular tissues adjacent to lipomas. And hearing loss, dizziness and tinnitus are the commonly presenting symptoms. Among these symptoms, hearing loss is the most comon, but sudden hearing loss, as in this case, has not been s the best treatment option for patients with these rare lesion. But surgery is indicated only when significant progresive or disabling symptoms are present. We experienced a case of right side C-P angle lipoma with sudden hearing loss in a 49-year old female who showed complete recovery of hearing by conservative therapy. With a review of literature, authors report a case of right C-P angle lipoma presented as sudden hearing loss. (Korean J Otolaryngol 2002 ;45 :1098-101)
Keloids are abnormal wound reactions, which develop from connective tissue as a result of skin trauma such as inflammation, burns, piercing or surgery in predisposed individuals. This fibrous growth extends beyond the boundaries of the original wound and rarely regresses. Keloids have a thick and glassy appearance. These characteristics distinguish keloids from hypertrophic scars,which are confined to the original wound and show spontaneous regression. Despite of various treatment options, there is no consensus on the best way to treat keloids. Surgical excision followed by radiation therapy is considered to be the most effective treatment available for severe recurrent keloids. We present three cases of patients with recurred keloids in the auricle, which were treated with surgical excision and adjuvant radiation therapy.

Background and Objectives:diseases are concerned about postoperative voice quality, there was no way to propose postoperative voice objectively. For this reason, the authors studied to synthesize predictive postoperative voice based on preoperative voice. Materials and Method:The authors evaluated 47 patients who experienced laryngeal microsurgery due to pathologic voice with benign laryngeal diseases. The voice was analysed by Computerized Speech Lab 430B. Linear Prediction and Pitch Synchronous Overlap and Add methods were used to synthesize the predictive voice. Asesments for the synthetic voice were sound
