面中区恶性肿瘤80例手术缺损的修复

Objective To evaluate the reconstructive methods of outcome of midface defects following the removal of malignant neoplasms. Methods Eighty cases (54 males, and 26 females, age ranging from 23-79, with a median age of 53.5 years) ,of midface malignant tumors from 1997-2006 in Beijing Tongren Hospital were retrospectively reviewed. The clinical data including the type of midface region defects,reconstructive methods and the therapeutic outcome were analyzed. Of the 80 patients,6 cases were with type Ⅰ ( external nasal ) defect,56 with type Ⅱ (maxillary) defect, 14 with type Ⅲ (naso-facio-maxillary)defect and 4 with type Ⅳ ( maxillary defect combined with naso-facio-orbital cutaneous deficiency). Results The defects after the removal of malignant tumors were repaired with pedicle tissue flaps in 31 cases and free tissue flaps in 49 cases, respectively, one-stage reconstruction accounting for 73 cases (91.2%). KaplanMeier analysis showed total 3-year and 5-year survival rates were 63.8% and 40. 6%, respectively.Conclusions One-stage reconstruction is a satisfactory method for the repair of midface defect after the removal of malignant tumor, with good clinical outcome. Selection of repair methods should be based on defect types.
