Analysis of patients with a cleft of the soft palate with special consideration to the problem of velopharyngeal insufficiency.

The evaluation of therapy concepts for children suffering from cleft palate is an enormous challenge in modern oral and maxillofacial surgery and related disciplines. In the present retrospective survey 1300 patients having clefts, including the soft palate, were studied with special regard to speech improvement operations. Nine hundred fifty four patients had a cleft lip, alveolus and palate and 346 patients only isolated cleft palate. In 25.6% of the patients it was necessary to perform a secondary velopharyngoplasty for speech improvement after soft palate closure. Age of the subjects at the time of operation, primary or secondary soft palate closure, and the type of clefting were not significant factors for performing subsequent velopharyngoplasty. However, significant differences with respect to the need for a secondary velopharyngoplasty after soft palate closure were found when comparing the surgical experience of the surgeons.
