The root of the flap was thoracodorsal artery and thoracodorsal vein, which was anastomosed with superficial temporal artery and vein, facial artery and vein, lingual artery and vein,and so on.During the operation, long thoracic nerve was dissected and anastomosed with facial nerve. The sizes of the flaps were 12 cm×8 cm16 cm×12 cm.Results All free-muscle flaps healed well after the transplant. The face and buccal area looked chubby and rounded. There were no obvious protuberance and discontentment on the buccal area. The shoulders of all patients moved well. The facial contourof the patients recovered well during the follow-up period (1.3 years). Conclusion The method has a good result, The long-term effect needs further study.
Objective To evaluate the application value of repairing the defects of the chest wall with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis. Methods From January 2002 to June 2005, five patients with defects in the chest wall underwent the prothesis with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis under general anesthesia. Focal cleaning was performed first; then, the skin flap was designed and taken (15 cm ×10 cm); and finally, the defects of the chest wall were repaired with the muscle flap of the musculus rectus abdominis. Results Of the 5patients, 4 had the flap healing by the first intention, and 1 had the delayed healing, with no complication. The skin flap had a good appearance, without edema orpigmentation. The X-ray examination showed that the shadow of the sternal sequestrum disappeared. There was no recurrence or complication during the follow-upfor 1-3 years (average, 18 mon). Conclusion The repairing of the defects in the chest wall with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis is a simple and effective surgical treatment for defects of the chest wall around the sternum, and this kind of treatment is worth applying extensively in clinical practice.
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.
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 investigate the reconstructional method of posterior wall of vagina after the resection of rectum carcinoma. METHODS From August 1991 to March 1996, 10 patients with rectum carcinoma were adopted in this study, among them, there were 4 cases belong to B stage of Dukas, and 6 cases belong to C stage of Dukes. In operation, rectum carcinoma and posterior wall of vagina were resected, and concurrent reconstruction was finished by using pedicled muscular flap of uterus. RESULTS The effect of operation were satisfactory except one case who was failed because of insufficient blood supply of the flap. Followed-up for 3-6 months, the posterior wall of vagina healed in 7 cases, the width of vagina was 2-3 fingers and the depth was 5-6 cm. CONCLUSION Reconstruction of the posterior wall of vagina with pedicled muscular flap of uterus was available in clinic. For its simplicity and feasibility, it’s suitable for the resection of rectum carcinoma in which the posterior wall of vagina was infiltrated.
Objective To introduce the current situation and prospect of the tissue-autografting, such as the flaps, muscle flaps, and bone(periosteum) flaps, andits application in reparative and reconstructive surgery. Methods Based on our own experiences and combined with the review of the literature at home and abroad, the latest development of the tissue autografting was analyzed. Results The femoral anterolateral flap, latissimus dorsi muscle flap, upper arm lateral flap, scap flap, temporal fascial flap and perforator flap are the frequently used in clinic. Of all the perforator flap had such advantages as better repair of the recipient sites and less damage of the donor site. Beacause of more advantages of the free myocutaneous flap transplantation, it substituted thefree muscle transplantation. The atissimus dorsi muscle myocutaneous flap was the most frequently used in the transplant of the vessels, with preserved function of the thoracodorsal nerve or with repair of the defected tissues by the bridge. The most common donor sites of the bone were ribs，iliac bone，fibula andscapula, so the severe bone defects or the bone nonunion, femoral head ischemic necrosis, and the bone graft from the tumor removal could be managed with the bones from those sites. Conclusion The autografting in repairing the tissue defect has become one of the most important surgical techniques in reparative and reconstructive surgery.
Objective To explore the application of personalized guide plate combined with intraoperative real-time navigation in repairing of mandibular defect using fibula muscle flap, providing the basis for the precise repair and reconstruction of mandible. Methods The clinical data of 12 patients (9 males and 3 females) aged from 23 to 71 years (mean, 55.5 years) between July 2019 and December 2021 were recorded. These patients were diagnosed as benign or malignant mandibular tumors, including 2 cases of ameloblastoma, 6 cases of squamous cell carcinoma, 2 cases of osteosarcoma, 1 case of adenoid cystic carcinoma, and 1 case of squamous carcinoma. All patients were treated with mandibular amputation, and then repaired by double-stacked three-segment fibula muscle flap. Preoperative virtual design scheme and guide plate were performed. During the operation, personalized guide plate combined with real-time navigation was used for fibular osteotomy and shaping. Thin-slice CT examination was performed at 2-3 weeks after operation, and was fitted with the preoperative virtual design scheme. The difference between the distance of bilateral mandibular angles relative to the reference plane in three-dimensional directions (left-right, vertical, and anterior-posterior) and the difference of the medial angle of the lower edge of the mandible reconstructed by fibula were measured, and the mean error of chromatographic fitting degree was calculated. Results The guide plate and navigation were applied well, and the fibula shaping and positioning were accurate. The fibula muscle flap survived, the incision healed well, and the occlusal relationship was good. All 12 patients were followed up 1-29 months, with an average of 17 months. There was no significant difference on the distance of bilateral mandibular angles relative to the reference plane in the left-right [(−0.24±1.35) mm; t=−0.618, P=0.549], vertical [−0.85 (−1.35, 1.40) mm; Z=−0.079, P=0.937], and anterior-posterior [(−0.46±0.78) mm; t=−2.036, P=0.067] directions. The difference of the medial angle of the lower edge of the mandible reconstructed by fibula was also not significant [(−1.35±4.34)°; t=−1.081, P=0.303)]. Postoperative CT and preoperative virtual design fitting verified that there was no significant difference in the change of the mandibular angle on both sides, and the average error was (0.47±1.39) mm. ConclusionThe personalized guide combined with intraoperative real-time navigation improves the accuracy of peroneal muscle flap reconstruction of the mandible, reduces the complications, and provides a preliminary basis for the application of visual intraoperative navigation in fibula muscle flap reconstruction of the mandible.
Objective To introduce the experience about thereconstruction of median sternotomy wound dehiscence. Methods From February 2002 to October 2004, 10 patients with median sternotomy wound dehiscence due to coronary artery revascularization were treated. There were 7 males and 3 females, aging from 68 to 76 years. The sizes of defects ranged from3 cm×5 cm to 5 cm×15 cm. After debridement of necrotic soft tissue, sternum and rib, infected median sternotomy wound was reconstructed with rectus abdominis myocutanous flap, pectoralis major myocutanous flap and latissimus dorsi flap or single muscle flap. The sizes of flaps ranged from 3 cm×5 cm to 5 cm×16 cm.Results Allpatients were followed up from 3 to 11 months with anaverage of 6 months. All the patients achieved healing by first intention with normal respiration and normal function of upper limbs. The wound of donor site healed well.No abdominal hernia and other complications occurred. The wound of donor site healed well.The results were satisfactory.Conclusion According to different stages of the disease and different conditions of an operation, the surgical management should vary with each individual.
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.
