SURGICAL METHOD FOR TREATING CONGENITAL HARD AND SOFT CLEFT PALATE Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves cutting mucous membrane and periosteum in the area of lateral hard palate portions. Cuts are done in anterior and middle hard palate part. Mucoperiosteal flaps are produced. The flaps are separated from nasal mucosa and bone part of the hard palate. Mucous and submucous layer are cut in retromolar zones beginning from Langenbeck incision back edge and finishing in glossal surface projection of mandibular alveolar process with pterygoid processes hamulus of the main bone being exposed. Soft tissues are detached from the processes in interfacial space layer located between musculus levator veli palatini and the hamulus to the pharyngopalatine muscle insertion site. Upper pole of musculus levator veli palatini tendons is cut in the cases of lacking mobility. Reticular implant manufactured from 40-60 mm thick titanium nickelide thread and cell size of 3x3-4x4 mm is sutured to mucoperiosteal flaps surfaces turned towards nasal cavity or to each other after moving them. The implants are attached to each other. The mucoperiosteal flaps are fixed by means of removable protection plate.

EFFECT: enhanced effectiveness of treatment; prevented flap divergence; forming solid connective tissue regenerate.
