Denervated palmaris longus tendon as a skeletal muscle transplant in circumferential pharyngoplasty.
The incidence of velopharyngeal incompetence (VPI) following cleft palate surgery is fairly high in our country. We have attempted to analyse the aetiology and then selected 50 cases of VPI from our group of operated cleft palates. These patients were then evaluated using cephalometry, speech rating, pressure studies and nasendoscopy. We identified 13 patients in whom there was incompetence due to failure of movement of the walls responsible for proper closure of the velopharyngeal port. In these patients we performed circumferential sling pharyngoplasty using denervated palmaris longus; since this procedure narrowed the port circumferentially. We re-evaluated these patients and the results have been gratifying. Speech rating improved and E.M.G. tracings after 6 months showed evidence of reinnervation of the Palmaris Longus.
