Abstract
We encountered two cases with transnasal leakage of fluid and hypernasality after adenotomy. One case was diagnosed as paralysis of the soft palate and the other as submucosal cleft palate. It was thought that adenotomy exacerbated the velopharyngeal incompetence in these two cases. In order to determine the preoperative status of velopharyngeal incompetence more precisely, we studied retrospectively 35 cases of submucosal cleft palate and congenital velopharyngeal incompetence.It was found that the correct diagnosis was not immediately determined in these cases. Moreover, it became clear that otitis media with effusion coexisted in about 60% of the cases. We concluded that it is important to perform a comprehensive diagnosis including a detailed history of birth and development, visual inspection and palpation of the palate, blowing examination and XP study.
