돌발성 난청환자 78예의 예후인자에 대한 고찰

Background and Objectives: There are many known prognostic factors such as patient’s age, treatment onset, initial hearing threshold, and dizziness in patients with sudden senosrineural hearing loss. The purpose of this study was to analysis prognostic factors in patients with sudden sensorineural hearing loss. Materials and Methods:We reviewed the medical records of 78 patients who were diagnosed as sudden senosorineural hearing loss and treated in Soonchunhyang University Hospital from February 1998 to October 2003, retrospectively. Results: Recovery was seen in 43 of 78 cases (55.1%). Patients who had been treated within a week after symptom onset had better recovery rate than those treated after a week. Patients with U-shaped pattern and ascending pattern of initial audiogram had a better recovery rate than others. Patients with mild and severe hearing loss had a better recovery rate than others. Patients without diabetes mellitus had a better recovery rate than with diabetes mellitus. But these prognostic factors did not showed correlation statistically (p>0.05). Age, sex, dizziness, hypertension, and CRF did not showed statistically significant correlation with final result of hearing recovery. Conclusions: We can predict hearing outcome of sudden sensorineural hearing loss more accurately on the basis overall prognostic factors. (J Clinical Otolaryngol 2004;15:98–102)
