METHOD FOR REMOVING VELOPHARYNGEAL INSUFFICIENCY CAUSED BY SOFT PALATE SHORTENING Russian patent published in 2006 - IPC A61B17/00 

FIELD: medicine, oral surgery, stomatology.

SUBSTANCE: one should cut out and mobilize mucous-periosteal flap and prepare vascular-nervous bundles. Then one should cut out and separate buccal tongue-shaped flaps so, that their foundation should be a mucous-periosteal flap. The length of tongue-shaped flaps corresponds to three fourth against the width of mucous-periosteal flap in area of ptery-mandibulo-maxillary folds, the width equals to the value of desired soft palate's lengthening, thickness being about 3-4 mm. Then it is necessary to prepare the ends of m. palatopharyngeus from both sides to suture them together followed by retrotransposition of soft palate downwards and backwards. Then one should suture broken hooks of pterygoid process of cuneiform bone with allotendinous ligature, which should be tightened and additionally sutured up to palatine aponeurosis in the center. Tongue-shaped flaps should be overturned for the angle of 180° onto wound surface of mucous-periosteal flap and sutured together in a "kiss"-type position with mattress sutures. Then one should cut out epithelial flaps with their foundation being in the site of flexure of overturned tongue-shaped flaps. Between wound surface in area of ptery-mandibulo-maxillary fold and mucous-periosteal flap, to the front against foundations of tongue-shaped flaps it is necessary to apply the suture to press deepithelized surface in the site of flexure of tongue-shaped flaps towards tissues in area of ptery-mandibulo-maxillary fold. Tongue-shaped flaps should be put into the defect between soft palate and hard palate's fragments to be sutured up to mucous-periosteal flap and to the edges of soft palate's mucosa and hard palate's nasal mucosa, then it is necessary to apply allotendinous ligature between soft palate and overturned sutured tongue-shaped flaps, then epithelial flaps should be overturned for the angle of 180° and put into peripharyngeal niches, wounds should be specially covered with protective plate. The innovation improves functional results of therapy due to restoring functions of nutrition and speech.

EFFECT: higher efficiency.
