METHOD FOR VESTIBULAR PLASTY OF MOUTH CAVITY IN ITS LATERAL DEPARTMENT Russian patent published in 2005 - IPC

FIELD: medicine, oral surgery.

SUBSTANCE: one should perform an incision along mucous-gingival border of patient's jaw up to periosteum, separate mucosa at the section of transitional fold, replace separated mucosa into area of deeper vestibular arch to be sutured to periosteum, cover wound surface with a not free fragment out of the section of alar-mandibular fold. One should perform the first incision to form a fragment at the part of mucous-gingival maxillary border behind the tuber, continue this incision downwards along anterior edge of medial alar muscle towards mandibular transitional fold behind the 8^th tooth. Then it is necessary to perform the 2^nd incision at the part of maxillary transitional fold behind the 8^th tooth by leaving 1 cm against the 1^st one. One should continue the incision along the cheek at projection of anterior edge of mandibular branch, connect the second incision with the onset of the first one, separate mucous-submucous fragment beginning from inferior end, moreover, the width of developed fragment in central department should correspond to 1 cm. One should rotate the fragment upon nutritive pedicle at the angle of 90 deg., apply the fragment onto wound surface of vestibular side of maxillary alveolar process, fix the fragment with sutures to mucous edges. In another variant, the first incision for developing a fragment should be performed at the part of transitional maxillary fold behind the 8^th tooth. One should continue this incision downwards along anterior edge of medial alar muscle to mandibular mucous-gingival border the 8^th tooth. Then one should perform the second incision at the part of maxillary transitional fold behind the 8^th tooth from the onset of the first incision by continuing this incision along the cheek at projection of anterior edge of mandibular branch towards transitional fold. Then one should separate mucous-submucous fragment by starting from superior edge, moreover, the width of formed fragment in central department should correspond to 1 cm. Then one should rotate the fragment upon nutritive pedicle at the angle of 90 deg. and apply it onto wound surface of vestibular side of mandibular alveolar part. The innovation suggested enables to improve functional and esthetic results of vestibular plasty of mouth cavity.

EFFECT: higher efficiency of vestibular plasty.
