Objective To investigate the method and the curative effect of postauricular muscular fasciae-periosteal flap and modified unwrinkle incision in parotidectomy. Methods From January 2006 to August 2008, 28 patients with benign lesions of parotid gland were treated. There were 17 males and 11 females aged 19 to 79 years old (average 50 years old),including 20 cases of mixed tumor, 5 cases of adenolymphoma, 1 case of branchial cleft cyst, 1 case of eosinophil ic hyperplastic lymphogranuloma, and 1 case of myoepithel ioma. Tumor masses were all prominent, with the diameter of 2.4-3.8 cm and partial-tough texture. The course of disease was 3-18 months (average 9.5 months). Parotid gland and tumor mass were resected with postauricular incision hidden within the hairl ine, introcession defect (3.0 cm × 2.0 cm × 1.0 cm-3.5 cm × 2.5 cm × 1.5 cm) were repaired with simultaneouly adopting postauricular muscular fasciae-periosteal flap (4.0 cm × 3.0 cm × 1.0 cm-5.0 cm × 4.0 cm × 1.5 cm) by turning the pedicle flap 180°. Results All incision healed by first intention and no necrosis of postauricular muscular fasciae-periosteal flap occurred. All patients were followed up for 6-24 months (average 12 months). The incision was hidden within postauricular hairl ine and shape of parotid realm was good. No sal ivary fistula, facial paralysis, and earlobe numbness occurred. No Frey syndrome were found by local iodine-starch tests. Conclusion Because of hidden incision, good repair effect of region introcession deformity, and fewer postoperative compl ications, the modified parotidectomy with postauricular muscular fasciae-periosteal flap and modified unwrinkle incision is a better method in parotidectomy.
Objective To investigate the surgical treatment method and the curative effect of tibial nonunion with superficial peroneal vascular fascia pedicel tibiofibular periosteal flap. Methods From January 1996 to December 2008, 18 cases of tibial nonunion were treated with superficial peroneal vascular fascia pedicel tibiofibular periosteal flap, interlockingintramedullary nail ing and cancellous bone graft of distal tibial. There were 14 males and 4 females, with an average age of 32.5 years old (range, 24-67 years old). Fracture site was middle in 10 cases and distal in 8 cases. Primary injury cause included 12 cases of traffic accident and 6 cases of bruise. The tibial nonunion reasons were manual reduction and plaster immobil ization in 8 cases, small spl int immobil ization in 4 cases, intramedullary nail fixation in 2 cases (no bone graft), plate fixation in 4 cases (including 3 cases of plate fixation and free il iac bone graft). Nonunion occurred after the first surgery. The time from nonunion to operation was 8 to 16 months, with an average of 10.5 months. The size of periosteal flap was 7 cm × 5 cm and distal tibial cancellous bone graft volume was 5-10 g. Results All incision achieved heal ing by first intention after operation without flap necrosis and infection. All patients were followed up 6-36 months with an average of 20.8 months. All tibial nonunion healed 5-7 months after operation. According to Johner-Wruh scoring, the results were excellent in 14 cases, good in 3 cases, and fair in 1 case; the excellent and good rate was 94.4%. Conclusion Superficial peroneal vascular tibiofibularfascia pedicel tibiofibular periosteal flap and interlocking intramedullary nail ing can attain good results in treating nonunion of tibia and fibula because of being stable internal fixation and promoting the heal ing of nonunion.
Objective To estimate clinical effect ofspin iliac deep vascular pedicled periosteum flap in repairing traumatic femoral neck of theca inside fracture in young and middleaged. Methods From April 1993 to September 2001, 12 cases of traumatic femoral neck fracture were given diaplastic operation with fixation of 3 centre hollow pressed bolt and were conducted under os traction bed and "C" arm X-ray machine. Spin iliac deep vascular pedicled periosteum flap wasstripped off, and transferred to the front of femoral neck fundus，then transplanted to the narrow inside of fracture through outer open door of articular capsule.Results All patients were followed up for 17 years. All fracture healedwithout femoral head necrosis, but mild arthritis appeared in 7 cases.Conclusion Vascular pedicled periosteum flap transfer of young and middle-aged femoral neck fracture, by decompression of femoral neck and reconstruction of blood circulation, can promote the fracture healing and decrease the wound and blood circulation destroy.
OBJECTIVE To investigate the therapeutical effect of treatment of ischemic necrosis of femoral head by the transfer of vascular pedicled iliac periosteum. METHODS From June 1983 to August 1997, 106 cases with ischemic necrosis of femoral head (II stage in 64 cases, III stage in 39 cases, IV stage in 3 cases) were treated by the transfer of vascular pedicled iliac periosteum with ascending branch of lateral femoral circumflex vessel or deep circumflex iliac vessel pedicle. RESULTS Followed up 2 years and 4 months to 16 years, there were excellent in 54 cases, better in 38 cases, moderate in 9 cases, poor in 5 cases, and 86.8% in excellent rate according to the criterion of the therapeutical effect on the repair and reconstruction of adult ischemic necrosis of femoral head. CONCLUSION Treating ischemic necrosis of femoral head by the transfer of vascular pedicled iliac periosteum has the advantage of constant pedicle, easily drawing materials and reliable therapeutical effect.
OBJECTIVE: To study the results of humeral fracture and non-union repaired by vascularized periosteal flap transfer. METHODS: The clinical data of humeral fracture and non-union in 23 cases were analysized retrospectively since 1995. Among them, minuted or several segmental fracture in 12 cases, non-union in 11 cases, and following injury of radial nerve in 7 cases. The operative method was open reduction, inner or external fixation with vascularized periosteal flap transfer. RESULTS: The period of follow-up was 6 months to 2 years. The repair result of all patients was excellent and good, but elbow joint motion in 2 cases of non-union was not satisfactory. The periosteal flap had good osteogenic ability. The period of bone union was 2 to 5 months in humeral fracture and non-union. And function of radial nerve was recovery. CONCLUSION: Transfer of distal humeral periosteal flap pedicled with radial collateral vessels is a better method for humeral fracture and non-union.
Based on the anatomical studies, the authors had designed an operation for treating old dorsal subluxation of the inferior radio-ulnar joint.The periosteum was longitudinally incised at the dorsal side of the lower ulna. forming musculo-periosteal flap, and a periosteal flap, and a periosteal valves of pronator quadratus. They were subluxation, passing the flap from palmar to the dorsal side through thc subperiosteal tunnel at the lateral margin of the radius corresponding to the ulna. Then it was circled round the lower end on the ulna and sutured to the muscular flap and the tough interosseous membranes at the palmar side, being used to stabilize the recuperated dorsal subluxation of the inferior radio-ulnar joint. The result of its clinical use was satifying.
ObjectiveTo investigate the effectiveness of tibial periosteal flap pedicled with intermuscular branch of posterior tibial vessels combined with autologous bone graft in the treatment of tibial bone defects. MethodsBetween January 2007 and December 2013, 19 cases of traumatic tibia bone and soft tissue defects were treated. There were 14 males and 5 females, aged from 18 to 49 years (mean, 28 years). The tibial fracture site located at the middle tibia in 6 cases and at the distal tibia in 13 cases. According to Gustilo type, 4 cases were rated as type Ⅲ A, 14 cases as type Ⅲ B, and 1 case as type Ⅲ C (injury of anterior tibial artery). The length of bone defect ranged from 4.3 to 8.5 cm (mean, 6.3 cm). The soft tissue defects ranged from 8 cm×5 cm to 17 cm×9 cm. The time from injury to operation was 3 to 8 hours (mean, 4 hours). One-stage operation included debridement, external fixation, and vacuum sealing drainage. After formation of granulation tissue, the fresh wound was repaired with sural neurovascular flap or posterior tibial artery perforator flap. The flap size ranged from 10 cm×6 cm to 19 cm×11 cm. In two-stage operation, tibial periosteal flap pedicled with intermuscular branch of posterior tibial vessels combined with autologous bone graft was used to repair tibial defect. The periosteal flap ranged from 6.5 cm×4.0 cm to 9.0 cm×5.0 cm; bone graft ranged from 4.5 to 9.0 cm in length. External fixation was changed to internal fixation. ResultsAll flaps survived with soft texture, and no ulcer and infection occurred. All incisions healed by the first intention. All patients were followed up 18-40 months (mean, 22.5 months). All graft bone healed, with the healing time from 3 to 9 months (mean, 6.5 months). No complication of implant loosening or fracture was observed. No pain and abnormal activity in the affected leg occurred. All patients resumed weight-bearing and walking function. The length of the limb was recovered and difference value was 0.5-1.5 cm between normal and affected sides. The function of the knee and ankle joint was good without infection, malunion, and equinus. According to the Johner standard at last follow-up, the results were excellent in 15 cases, good in 3 cases, and fair in 1 case, with an excellent and good rate of 94.7%. ConclusionTibial periosteal flap pedicled with intermuscular branch of posterior tibial vessels combined with autologous bone graft is an effective method to treat bone defect of the tibia.
