FIELD: maxillofacial surgery.
SUBSTANCE: after opening of sinus, damaged bone tissue and pathologic contents are removed, endonasal canal for postoperative drainage is formed, and bone defect is replaced by titanium nickelide tissue made from thread having diameter 50-60 μm and mesh size 10 to 1000 μm. Titanium nickelide tissue is attached to soft tissues by means of interrupted sutures in the region of anterior, superior, and posterior borders. Inferior border is placed either under periosteum of the alveolar outgrowth above gingival border by 1-2 mm or, when teeth are missing, under periosteum of the bone portion of hard palate.
EFFECT: reduced risk of detachment of sutures and prevented destructive changes of bone walls of sinus.
