Correction of maxillofacial expansive deformities resulted from cystic lesions of the mandible by suction drainage / 中华整形外科杂志

<p><b>OBJECTIVE</b>To prospectively investigate the effectiveness of suction drainage for correction of maxillofacial deformities caused by cystic lesions of the mandible.</p><p><b>METHODS</b>Suction drainage was performed in 21 cases with large cystic lesions of the mandible which had expanded facial contour. Clinical and radiological examinations of these patients were carried out regularly. The volume of the cavity was measured during treatment. The expansion indexes on axial CT image and area of the cyst on a panoramic radiograph were measured preoperatively and postoperatively. The curettage via intraoral incision was completed until the extent of disease significantly shrunk.</p><p><b>RESULTS</b>After a mean duration of suction drainage of 5.1 months, the volume and the size on the panoramic radiographic of the cystic lesions were reduced by an average of 84% and 63% respectively. The expansion indexes were reduced notably during treatment. Computerized tomography of the mandible showed that the contour of expanded mandible was restored greatly and notable new bone was formed in the area of cortex perforation.</p><p><b>CONCLUSIONS</b>Suction drainage is a useful treatment modality for the primary management of giant cystic lesion of the mandible, and can fast correct maxillofacial deformities caused by bony expansion and perforation in the area of cystic lesions.</p>

<p><b>OBJECTIVE</b>To observe the therapeutic effect of 120 cases venous malformations treated by cryotherapy combine with pingyangmycin.</p><p><b>METHODS</b>Pingyangmycin was injected into venous malformations and cryotherapy with liquid nitrogen was followed immediately.</p><p><b>RESULTS</b>Cure rate was 77.5%, incomplete cure rate was 17.5% and efficiency rate was 5%.</p><p><b>CONCLUSIONS</b>The method of cryotherapy combine with pingyangmycin injection to treat venous malformations has good effect.</p>

Clinical analysis about survival condition of different types of platysma myocutaneous flaps / 中华整形外科杂志

<p><b>OBJECTIVE</b>To compare the postoperative outcome among different types of platysma myocutaneous flaps by reviewing 54 cases.</p><p><b>METHODS</b>From 1984 to 2004, 54 patients with oral cancer underwent immediate reconstruction of intraoral defects using the platysma myocutaneous flaps. In 54 cases, 12 cases were transversal platysma myocutaneous flaps and the other 42 cases were vertical platysma myocutaneous flaps. In these 42 cases, 26 cases preserved facial artery and vein yet 16 cases didn't preserve them. The survival condition of these flaps were compared.</p><p><b>RESULTS</b>In the 12 cases of transversal platysma myocutaneous flaps, 10 cases survived totally and 2 cases had partial necrosis. In the 26 cases of vertical platysma myocutaneous flaps preserved facial artery and vein, 23 cases survived completely and 3 cases had partial necrosis. However, in the 16 cases of vertical platysma myocutaneous flaps in that facial artery and veins were not preserved, 10 cases survived completely, whereas 4 cases had partial necrosis and 2 cases had complete necrosis.</p><p><b>CONCLUSIONS</b>The survival rates of platysma myocutaneous flaps that didn't preserve facial artery and vein were low. Its clinical use should be prudent.</p>
