[Analysis of middle ear function of the patients with cleft palate after palatoplasty].

Objective

To investigate the middle ear function of the patients with cleft palate pre and post palatoplasty.

Methods

76 patients with cleft palate were investigated by clinical history and audiology examinations including electric otoscopy,tympanometry and click-ABR threshold.

Results

The risk for middle ear function decreased with advancing age in the first 5 years. It was noticed that the otologic outcomes was related to the CP type. During long time follow-up, the frequency with the middle ear function disorder was always high within the CP patients but the proportion of the patients received tympanostomy tubes was low relatively. The prevalence of middle ear dysfunction did not differ with the time of cleft palate repair.

Conclusion

The patients with cleft palate have middle ear function dysfunction in a long period of time,therefore a standard long-time follow-up system is necessary.
