METHOD FOR SURGICAL MANAGEMENT OF MAXILLARY OSTEONECROSIS Russian patent published in 2015 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: Kocher-Weber's surgical approach is exercised. With an anterior surface of the upper jaw and orbital bone skeletonised, peripheries of the changed bone tissue are delimited. A maxillary osteotomy extends to an infraorbital border. A preauricular approach of 3-4 cm long starts from the same side at 1-1.5 cm from a tragus and extended to a temporal region to form T-approach to a temporal muscle. A musculofascial flap is dissected and mobilised. A tunnel is created in tissues above the orbital bone and maxillary arch. The flap is delivered and stretched above the orbital bone and arch without applying an osteotome technique to the latter ones. The residual space between the muscles is filled with quickly resorbable material. The wound is closed in layers.

EFFECT: by applying the plastic repair technique using the pedicle muscle flap, the method enables providing a good stable effect, avoiding making additional osteotomy lines for the flap delivery, reducing postoperative complications.
