Objective To investigate surgical strategies using bilateral pectoralis major muscle flaps for the treatment of sternal dehiscence after cardiac surgery. Methods From May 2005 to October 2010，21 patients with sternal dehiscence, sternal osteomyelitis and mediastinitis after cardiac surgery were admitted to Beijing An Zhen Hospital of Capital Medical University. There were 13 male patients and 8 female patients with their age of 53-72 （64.5±7.8） years. There were 19 patients after coronary artery bypass grafting （CABG） and 2 patients after heart valve replacement. The non-viable and necrotic bones were debrided and sternal wires partially or completely removed. The sternal origins of pectoralis major were released on both sides. The pectoralis major muscle flaps were tensionlessly sutured across medially over the sternal defect. Multiple suction drains were placed and removed in due time. The skin was intermittently closed. Results All the pectoralis major muscle flaps lived well after surgery，and all the patients were discharged in 2 weeks after surgery. Twenty patients were discharged with complete wound closure，and 1 patient had wound fistula and infection after removal of suction drains that was healed after another surgery to resect the wound fistula. During 6 month follow-up，sternal wound healed well in all the patients with normal thoracic appearance，and none of the patients had abnormal respiratory movement, infection recurrence or persistent infection. Conclusion Bilateral pectoralis major muscle flap technique is a positive and efficient surgical strategy for the treatment of refractory sternal dehiscence after cardiac surgery.
Objective To investigate the effectiveness of distally pedicled peroneus brevis muscle flaps and reverse sural neurovascular island flaps for post-traumatic chronic calcaneal osteomyelitis and soft tissue defects. Methods Between January 2008 and January 2012, 9 patients suffering from post-traumatic chronic calcaneal osteomyelitis and soft tissue defects were treated, including 8 males and 1 female with an average age of 33 years (range, 18-46 years). The left heel was involved in 4 cases, and right heel in 5 cases. Infection occurred after reduction and internal fixation of closed fractures of the calcaneus in 7 cases, and open calcaneal fracture and soft tissue defect in 2 cases. The disease duration was 2 months to 3 years (mean, 5 months). Purulent secretion, tissue necrosis, or sinus formation was observed in all wounds. The results of bacterial culture were positive. X-ray and CT examination showed uneven density of calcaneus and bone cavity or dead bone formation. After thorough debridement, the size of bone defect ranged from 3 cm × 3 cm × 3 cm to 6 cm × 4 cm × 3 cm; the size of soft tissue defect ranged from 7 cm × 3 cm to 12 cm × 7 cm. The distally pedicled peroneus brevis muscle flaps (11 cm × 3 cm-16 cm × 4 cm) were used for bone defect repair, and reverse sural neurovascular island flaps (8 cm × 4 cm-14 cm × 8 cm) for soft tissue defect. The donor site was directly sutured in 6 cases and repaired by skin graft in 3 cases. Results After operation, reverse sural neurovascular island flaps survived in 9 cases, and all wounds healed by first intention. No necrosis or liquefaction of distally pedicled peroneus brevis muscle flaps was observed. Incision at donor site healed by first intention, and skin grafts at donor site survived. All cases were followed up 6-24 months (mean, 13.5 months). The flaps had good texture. No recurrence of osteomyelitis was observed. Basic weight-bearing walking function was restorated. No obvious calcaneal collapse happened. Conclusion The distally pedicled peroneus brevis muscle flap combined with reverse sural neurovascular island flap is one of the effective methods to treat post-traumatic chronic calcaneal osteomyelitis with soft tissue defect, with the advantages of simple operation and good blood supply.
【Abstract】 Objective To investigate the effectiveness of pedicled sternocleidomastoid muscle flap in repairing defect after parotidectomy by comparing with direct suture. Methods The clinical data were retrospectively analyzed, which were from 73 patients with parotid tumor undergoing parotidectomy between January 2002 and April 2010. After parotidectomy, defects were repaired with pedicled sternocleidomastoid muscle flap in 38 cases (flap group) and with direct suture in 35 cases (control group). There was no significant difference in gender, age, disease duration, tumor location and size between 2 groups (P gt; 0.05). Meanwhile the complications, such as local introcession deformity, Frey’s syndrome and parotid gland fistula were observed. Results In flap group, the flaps were all alive and incisions healed by first intention; in control group, all incisions healed by first intention. All patients were followed up 6-98 months and no tumor recurred. There was significant difference in local introcession deformity between 2 groups (χ2=53.202, P=0.000). The parotid gland fistula was found in 1 case (2.6%) of the flap group and in 8 cases (22.8%) of the control group, Frey’s syndrome was found 1 case (2.6%) of the flap group and in 20 cases (57.1%) of the control group, showing significant differences between 2 groups (P lt; 0.05). Conclusion The use of pedicled sternocleidomastoid muscle flap for defect repair after parotidectomy can avoid the complications of local introcession deformity, Frey’s syndrome, and parotid gland fistula.
ObjectiveTo summary the application and effectiveness of the posterior radial collateral artery (PRCA) compound flap in reconstruction of soft tissue defect after tongue cancer excision. MethodsBetween August 2011 and October 2011, 5 patients with squamous cell carcinoma underwent tongue defects reconstruction with compound flap with extended lateral arm free flap (ELAFF) and triceps muscle flap (TMF) after ablation in one-stage. All patients were male with an average age of 59 years (range, 43-71 years). The disease duration was 25-60 days (mean, 42 days). After extended resection, 3 cases had 1/3 tongue and mouth floor defect, and 2 cases had 1/2 tongue and mouth floor defect. The size of ELAFF ranged from 7 cm × 5 cm to 9 cm × 5 cm, and the size of TMF ranged from 3 cm × 3 cm to 4 cm × 4 cm. The donor sites were directly sutured. ResultsAll compound flaps survived. The wounds at donor sites and recipient sites healed primarily. The patients were followed up 6 months. After operation, the tongue had good appearance and motion; the patients had clear voice and no dysphagia. No recurrence was observed during follow-up. Local numbness appeared at the donor sites, but the function of the elbows was normal. ConclusionThe application of the compound flap of ELAFF and TMF based on PRCA perforator is a better option to reconstruct tongue defects for its reliable blood supply, appropriate thickness, easy operative procedures, and less complication.
ObjectiveTo investigate the effectiveness of the mortise-tenon orbicularis oris muscle flap for philtrum column deformity secondary to the unilateral cleft lip repair. MethodsBetween January 2009 and August 2011, 43 patients with philtrum column deformity secondary to unilateral cleft lip repair were treated. There were 23 males and 20 females with an average age of 23.6 years (range, 18-31 years). The left philtrum column was involved in 26 cases, and the right side in 17 cases. Cleft lip was repaired with Millard I in 15 cases and with Millard II in 28 cases. The time between cleft lip repair and philtrum column deformity correction was 15-30 years (mean, 21.7 years). The bilateral double orbicularis oris muscle flap was obtained, and then was divided horizontally into two layers. The overlapping suture of the bilateral lower muscle flap was perfomed, and the upper layer muscle was designed into the mortise-tenon orbicularis oris muscle flap and was sutured with contralateral skin. ResultsAll incisions healed by first intention. Forty cases were followed up 13.4 months on average (range, 6-34 months). The patients achieved satisfactory effects in bilateral symmetry philtrum column and normal concave shape. At 6 months after operation, significant improvement was observed in 38 cases and no obvious improvement in 2 cases. ConclusionThe mortise-tenon orbicularis oris muscle flap is a simple operation and can obtain good results in the appearance and function of the upper lip in the correction of philtrum column deformities secondary to the unilateral cleft lip repair.
Objective To discuss the surgery procedure and the cl inical effectiveness of repairing skin and soft tissue defects in the lateral foot and the heel with the abductor digiti minimi muscle flap. Methods Between July 2002 and October 2010, 8 patients with skin and soft tissue defects in the lateral foot and the heel were treated. There were 6 males and2 females with an average age of 42 years (range, 28-65 years). The locations were the left foot in 5 cases and the right foot in 3 cases. Defects were caused by ulcer of the heel in 2 cases, by poor heal ing of incision after calcaneus fracture surgery in 1 case, and by crushing in 5 cases. The defect size ranged from 1.5 cm × 1.0 cm to 8.0 cm × 2.6 cm. The disease duration was 30 minutes to 26 months. The result of bacterial culture was positive in 2 cases. After 9 to 15 days of debridement and dressing change, defects were repaired with the abductor digiti minimi muscle flap of 5.6 cm × 1.5 cm to 7.6 cm × 1.8 cm at size. The donor sites were sutured directly. Results Partial necrosis of muscle flap occurred in 1 case at 4 days after operation, which was cured by symptomatic treatment, and the other muscle flaps survived. All incisions of the donor sites healed by first intention. The muscle flaps survived and the granulation grew well at 9-21 days after operation, and the muscle flap wounds were repaired by free leg edge thickness skin grafting. Wounds were repaired by one-stage free skin grafting in 1 case and by two-stage free skin grafting in 7 cases; all skin flaps survived and wounds healed by first intention. Seven patients were followed up 9-18 months (mean, 11 months). The appearance, texture, and sensation were satisfactory. The two-point discrimination was 16-23 mm (mean, 19.5 mm). Epidermal abrasion occurred in 1 case of heel ulcer after weigt-bearing walking. Hallux valgus and muscle weakness occurred in 1 case of necrosis of the peroneus length tendons; and the satisfactory results were achieved in the other patients. Conclusion It has satisfactory effectiveness to use the abductor digiti minimi muscle flap for repairing skin and soft tissue defects in the lateral foot and the heel, which has the advantages of easy-to-operate, safe, less injury at donor site, goodappearance and texture, and good recovery of sensation.
Objective To investigate the method of combining radial forearm free flap and adjacent tissue flap in reconstruction of palatomaxillary defects and its effectiveness. Methods Between March 2005 and May 2010, 17 patients with palatomaxillary defects were treated. There were 11 males and 6 females with an age range of 45-74 years (mean, 62.5 years), including 1 case of benign tumor and 16 cases of malignant tumors (7 cases of squamous cell carcinoma of palate, 1 case of recurring squamous cell carcinoma of palate, 1 case of malignant melanoma of palate, 1 case of adenoid cystic carcinoma of palate, 1 case of malignant melanoma of maxilla, 1 case of ductal carcinoma of maxilla, and 4 cases of squamous cell carcinoma of maxilla). The maxillectomy defect ranged from 7.0 cm × 5.5 cm to 10.0 cm × 7.5 cm. According to Brown’s classification for the maxillectomy defect, there were type II in 15 cases, type III in 2 cases. Palatomaxillary defects were repaired with radial forearm free flap and buccal fat pad in 11 cases, and with radial forearm free flap, buccal fat pad, and mandibular osteomuscular flap pedicled with temporal muscle in 6 cases. The effectiveness was evaluated after operation by observing the vitality of the flap, the functions of speech, swallowing, breath, and the facial appearance. Results All cases were followed up 6-12 months without tumor recurrence. All flaps and skin grafts at donor sites survived. The functions of seech, swallowing, and breath were normal without obvious opening limitation. The facial appearance was satisfactory without obvious maxillofacial deformity. No enophthalmos occurred in patients with orbital floor and infraorbital rim defects. The patients had no oronasal fistula with satisfactory oral and nasal functions. Conclusion According to the type of palatomaxillary defects, it can have good early effectiveness to select combining radial forearm free flap and buccal fat pad or combining radial forearm free flap, buccal fat pad, and mandibular osteomuscular flap for repairing defects.
