Surgical mesh has been used since the 1950s to repairabdominal hernias. In the using surgical mesh products 1970s, gynecologists began to indicate the repair of pelvic organ prolapse （POP）, and in the 1990s, gynecologists began using surgical mesh for POP. Then the U.S. Food andDrug Administration （FDA） approved the first surgical mesh product specifically for use in POP.展开更多

METHODS Eight patients with carcinoma of the maxillary sinus underwent a modified midfacial degloving operation. The tumors were classified according to the 2002 AJCC system. The TNM staging of the cases was as follows： 1 T4aN0M0, 2 T3N0M0 and 5 T2N0M0. Of the 8 cases, 1 patient underwent extended maxillectomy; exenteration of the orbit; tumorectomy of the sphenomaxillary and infratemporal fossae. Two patients received a total maxillectomy, and 5 a partial resection of the maxilla. Postoperative pathological report： 4 well-differentiated squamous carcinoma, 2 moderately-differentiated squamous carcinoma, 1 mucoepidermoid carcinoma and 1 adenoid cystic carcinoma.RESULTS A modified midfacial degloving operation can sufficiently expose a field of operation, resect the tumor within a safe margin, and leave no facial cicatricles. One patient died of intracranial metastasis 8 months after operation. We observed no recurrences or metastasis in other patients during the period of follow-up.CONCLUSION The major advantages of employing the modified midfacial degloving in maxillectomy is that a facial incision can be avoided. It has an advantage of minimal invasive surgery展开更多

Methods: An animal model was developed to permit daily monitoring of neovascularization of the flap with autoradiography, tissue transparent technique, gross observation and histological examination. Results: The revascularization of the flap was chiefly raised from the surrounding tissues. The pedicles of 334 cross finger flaps of the patients were successfully divided from 1 to 5 d after operations, averagely 3.3 d. All of the cases showed satisfatory results according to a follow up survey of 3 to 72 mon. The results further proved that the revascularization of the cross finger flaps had accomplished within 3 d. Conclusions: It suggests that the division of a cross finger flap can be carried out between the 3rd and 5th day after operation with a high degree of safety.展开更多
