The pectoralis major myocutaneous flap was used to repair laryngopharyngeal and esophageal defect following radical excision of pharyngeal and inferior laryngeal carcinomas in 3 cases. The results were susscessful. The patients were follwedup for 6 months to 3 years. The deglutition functions were all reestablished, the general nutritional conditions were improved, and no recurrence or distant metastasis was observed. The advantages of this operative procedure were discussed.
Objective To discuss and evalue the effects and the advantages of pectoral is major myocutaneous flap in repair of defect caused by resection of tonsillar cancer. Methods The data were retrospectively summarized from 10 patients with recurrent tonsillar cancer after radical radiotherapy from January 1998 to December 2005, including 7 cases of squamouscell carcinoma, 2 cases of undifferentiated carcinoma, and 1 case of adenoid cystic carcinoma. There were 8 males and 2 females, aged 43-68 years with an average of 58 years. All cases were classified as stages III and IV before radiotherapy according to staging standard of oropharyngeal cancer (International Union Against Cancer, 1997). The time of relapse was 6-32 months after radiotherapy. Recurrent tonsil cancer invased tongue base, soft palate, posterior wall of pharyngeal, parapharyngeal space, and palate. Tumor size was from 4 cm × 2 cm to 8 cm × 5 cm. Seven cases were accompanied by lymph node metastasis. After carcinoma were completely resected and defects were reconstructed by pectoral is major myocutaneous flap of 7 cm × 5 cm- 12 cm × 9 cm. The donor sites were sutured directly. Results After operation, pectoral is major myocutaneous flap completely survived in 9 cases. Partial necrosis of pectoral is major myocutaneous flap was found in 1 case; after treatment, the necrotic flap remained small pharyngeal defect. Incision at donor site healed by first intention in 10 cases. All patients showed satisfactory functions of respiratory, voice, and swallowing with no compl ication. Ten patients were followed up 2 years to 5 years and 8 months. The 3-year survival rate was 66.7% (6/9), and the 5-year survival rate was 20.0% (1/5). Conclusion Pectoral is major muscle flap has a high survival rate, which is safe, rel iable, easy-to-operate, and can repair larger defect. Pectoral is major myocutaneous flap is an ideal material in repair of defect caused by resection of recurrent tonsillar carcinoma after radiotherapy.
Twohundrednineteen orofaciomaxillary tumours, 18 benigns and 201 malignancies, were repaired by pectoralis major myocutaneous flaps following their resections. The types of flaps used in the repair were: single island myocutaneous flaps in 201 cases, doubleisland myocutaneous flaps in 16 cases, and myocutan eous skeletal flaps in 2 cases. The results were susscessful in 201 cases and failure in 18. The advantages and indications of using pectoralis major myocutaneous flaps were discussed. The method of design and its relevent surgical thechniques were introduced, and the factors responsible for the success and failure were analyzed. It is noted that the correct and meticulous operative techniques were the main factors leading to operative success.
ObjectiveTo summarize surgical experience and explore the best treatment strategy for the management of complicated mediastinitis after cardiac surgery. MethodsClinical data of 18 patients who received vascularized muscle flap transposition combined with negative pressure wound therapy (NPWT)for the treatment of complicated mediastinitis after cardiac surgery in one stage in the Department of Cardiac Surgery of Beijing Anzhen Hospital, Capital Medical University between June 2006 and December 2012 were retrospective analyzed. There were 12 male and 6 female patients with their average age of 65.5±8.2 years. The average interval between cardiac surgery and vascularized muscle flap reconstruction was 12.5±5.8 days. ResultsPostoperatively, 1 patient died of recurrent mediastinitis, sepsis and multiple organ dysfunction syndrome. Seventeen patients had an uneventful postoperative recovery and one-stage wound healing. Postoperative hospital stay was 18.6±7.2 days and wound healing time was 4.5±2.4 weeks. All the 17 patients were followed up for over 6 months, no recurrent mediastinitis was observed, and they had a good quality of life. ConclusionVascularized muscle flap transposition combined with NPWT is a simple and effective surgical strategy for the treatment of complicated mediastinitis after cardiac surgery in one-stage.
ObjectiveTo investigate the feasibility of the bipaddled split pectoralis major myocutaneous flap for immediate reconstruction of oral mucosal defects and neck defects after resection of recurrent oral cancer. MethodsSix patients with oral mucosal defects combined with neck defects after recurrent oral cancer resection were treated with bipaddled split pectoralis major myocutaneous flap between September 2013 and September 2014. There were 5 males and 1 female with an average age of 54.7 years (range, 45-62 years), including 4 cases of recurrent tongue cancer, 1 case of recurrent mandibular gingival cancer, and 1 case of mouth floor carcinoma. All patients underwent local recurrence at 8 to 14 months after first operation, with no distant metastasis. The defects of the intraoral mucosa was 4.0 cm×2.5 cm to 6.5 cm×3.5 cm and the defect of the neck skin was 5.5 cm×3.5 cm to 7.5 cm×5.0 cm. The pectoralis major myocutaneous flaps (14.0 cm×3.5 cm to 17.0 cm×5.5 cm) were incised at the level of the 3rd to the 4th rib, and then split down along the muscle fiber till about 2 cm away from the thoracoacromial vessels, forming 2 independent skin paddles with 1-2 branch vessels to the pedicles of the distal ones. The distal skin paddles were used for oral reconstruction while the proximal paddles for repair of neck defects. The chest donor sites were sutured directly. ResultsCervical haematoma and infection happened in 1 patient respectively after operation, and were cured after symptomatic treatment. All 6 split pectoralis major myocutaneous flaps with 12 skin paddles completely survived. All patients were followed up 6 to 18 months (mean, 11 months). One patient died of pulmonary metastasis at 8 months after operation and the other 5 survived without relapse or metastasis during follow-up. The intraoral paddles showed good shape with satisfactory speech function and swallowing recovery. The paddles also healed perfectly on the neck with flat outlooks, and all patients obtained full appearance and free movement of the neck. No fistula formed on the submandibular region and neck. ConclusionThe bipaddled split pectoralis major myocutaneous flap can complete simultaneous immediate reconstruction of oral mucosal defect and neck defect. It is very useful in the treatment of recurrent oral cancer.
Objective To explore the outcome of hypopharynx reconstruction by using remaining laryngeal mucosa flap and pectoralis major myocutaneous flap in advanced pyriform sinus cancer.Methods Twelve patients with pyriform sinus cancers underwent hemilaryngectomy and partial pharyngectomy, two patients underwentcervical esophagectomy at the same time. The defects were reconstructed by remaining laryngeal mucosa flap. Four cases were involved in the bilateral larynx, received total laryngectomy and were repaired by pectoralis major myocutaneous flap. Results There was no operative fatal case and all flaps survived. Only one suffered from postoperative pharyngocutaneous fistulas, whose defect was reconstructed by remaining laryngeal mucosa flap and had radiotherapy. All patients could swallow ordinary food and had no benign esophagostenosis and pharyngostenosis after operation. Out of 16 pateints, 1 case died of general metastasis;3 cases died of local tumor relapse, tumor relapse of cervical lymphonode and lung metastasis respectively within 1 year after operation; the other 12 casessurvived over 2 years.Conclusion The advantage of hypopharynx reconstruction with remaining laryngeal mucosa flap is simple and convenient with less trauma and complication. The reconstruction should be completed by using the pectoralis major myocutaneous flap when the bilateral larynx are involved in.
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.
The pectoralis major muscle or myocutaneous flap is characterized by its easy dissection and free rotation, as well as abundance of blood supply and tissue mass of the flap, so that it was often used in repairing the wound over the mandibulo-cervico-thoracic area. From 1989 to 1996, 11 cases with long-standing wound of this area were difficult to repair with the traditional method, but were treated with transposition of this type of myocutaneous flap. The myocutaneous flap was applied in 8 case and muscle flap in 3 case. The flap area ranged from 12 cm x 8 cm to 26 cm x 18 cm. All the flaps survived, and excellent results were achieved. The technique and design of the operation were reported in details. It was concluded that the process was easy to perform, and the flap had abundant blood supply and high resistance to infection.
