There is a possibility that pharyngeal flap surgery has an adverse effect on the nose, but little is known about this problem. We examined the incidence of sinusitis, sensation of nasal obstruction and disturbed olfactoryacuity in 25 cleft palate patients over 15 years of age who had had pharyngeal flap surgery. Nasal airway resistance was determined by the active-anterior method. The control group consisted of 43 cleft palate patients over 15 years of age without pharyngeal flap surgery.Fourteen cleft palate patients were examined before and after pharyngeal flap surgery with anterior rhinoscopy and determination of nasal airway resistance by the active-anterior method. The subjective sensation of nasal obstruction was also noted before and after surgery.Furthermore, the nasal airway resistance was measured in 23 cleft palate patients with pharyngeal flap by both the active-anterior and active-posterior methods to determine whether the pharyngeal flap increases resistance.1) There was no significant difference in the incidence of sinusitis, sensation of nasal obstruction or disturbed olfactory acuity between patients with and those without pharyngeal flaps. The difference in nasal airway resistance between the two groups was not significant.2) In 14 cleft palate patients, there was no increase of anterior rhinoscopic findings after the pharyngeal flap surgery and there was no significant change in nasal airway resistance after the surgery, but 2 of the 14 complained of slight aggravation of the sensation of nasal obstruction 5 months or more after surgery.3) The difference in the nasal airway resistance measured by the active-anterior and active-posterior methods in patients with pharyngeal flap was slight. It was considered that on nasal airway resistance the pharyngeal flap has little effect.
