Between 1980 and 1989, 82 velopharyngoplasties have been carried out in the Department of Oral and Maxillofacial Surgery at the Medical University of Hannover. Speech results of 51 of these patients, including 39 patients with cleft lip and palate, could be followed up in the context of a clinical follow-up examination. Besides evaluation of speech results by two senior speech pathologists and two untrained listeners, a frequency analysis of the speech results with a sonograph was obtained. Nasal air loss was documented with a fogged-mirror test and computer aerometry. Whereas in 37 of 51 patients a normal or almost normal colloquial speech could be demonstrated, 30 of 39 patients with cleft lip and palate showed a normal or almost normal realization of the test sentences. Thirty of the 37 patients (81.08 percent) with normal or almost normal colloquial speech showed extensive mobility of the lateral pharyngeal wall. Symmetry of the velopharyngeal flaps seemed to have no influence on the speech result. With a fogged-mirror test, an average reduction of mirror fogging from 2.0 rings preoperatively to 0.9 rings postoperatively could be shown. In 31 patients, there was no longer any air loss postoperatively. Besides one rupture of a flap, two flaps had to be diminished in their lateral dimensions because of excessive size. We regard the cranially pedicled pharyngeal flap as an important operative procedure for improving speech results, especially in cleft lip and palate patients.
