BACKGROUND: The aim of this study was to evaluate the prevalence and type of on auditory dysfunction in adult patients operated for cleft palate based on the tympanometric and audiometric findings.
METHODS: This prospective, cross sectional study included adult patients who had undergone cleft palate repair with intravelar veloplasty in childhood. Hearing evaluation was performed using pure-tone audiometry and middle ear pathology was evaluated by impedance audiometry. All patients were matched with healthy controls of similar age and gender. The prevalence ratio was used to calculate the incidence of hearing anomalies, and Fisher’s exact test was used to analyze significance.
RESULTS: Sixty-four ears were evaluated in 32 patients with cleft palate. Clinically significant hearing loss was present in 46.8% of patients, of whom 40.6% had mild hearing loss and 6.3% had moderate loss. Impedance audiometry revealed fluid accumulation in 37.5% of patients, and abnormal middle ear pressure in 12.5%.
CONCLUSIONS: Patients with a history of repaired cleft palate in childhood are more prone for hearing loss and pathological changes in the middle ear as compared to normal controls.
