Abstract
OBJECTIVE: The aim of this retrospective study was to analyze the recovery rate of sudden sensorineural hearing loss in children, and explore the prognostic factors in order to guide the clinical diagnosis and treatment.
METHOD: A retrospective review was conducted for the prognosis of children with sudden sensorineural hearing loss during the past 5 years (from November 2010 to May 2015) in Chinese PLA General Hospital. This paper have a complete clinical data of 101 patients (113 ears)with sudden hearing loss, ranging from 0 to 18 years old Patients were divided into four groups according to hearing recovery and eight putative prognostic factors were analyzed.
RESULT: Among 101 patients (113 ears), the ratio of male and female was 60:53. Treatment was initiated from 1 to 183 days after disease onset, with an average of (18.5 ± 22.1) d. Bilateral and unilateral hearing loss were 24 ears and 89 ears, respectively. The proportion of mild hearing loss, moderate hearing loss, severe hearing loss and profound hearing loss were 7.1%, 6.2%, 23.9% and 62.8%, respectively. Vertigo and tinnitus occurred in 54.9% and 77.9% of the patients, respectively. After the treatment, the complete recovery rate was 9.7% and the overall recovery rate was 36.3%. The degree of hearing loss, earlier treatment onset, sex and bilateral involvement were significantly associated with hearing recovery (P < 0.05).
CONCLUSION: Sudden sensorineural hearing loss in children was generally identified as severe and profound hearing loss, but after positive and timely treatment, it can be improved or even cured. The mild hearing loss, earlier treatment onset, unilateral hearing loss and female were positive prognostic factors. The concurrence of tinnitus or vertigo, the results of ABR and DPOAE had no significant influence on prognosis.
