In order to observe the morphological feature and blood supply of the pedicled trapezius myocutaneous flap, dissection was carried out on 114 sides of 54 cadavers. It was demostrated that trapezius muscle had multiple sources for its blood supply, including (1) dorsal scapular artery; (2)transvers cervical artery; (3) occipital artery and (4)spinal perforating artery. The dorsal scapular artery may originate from the same stem with the transvers cervical artery (68.4%), or originate seperatly (31.6%). Thirteen patients had radical resection for malignant tumour of head and neck, and were combined with pedicled trapezius myocutaneous flap, in which 6 with upper trapezius myocutaneous flap and 7 with lower trapezius myocutaneous flap. The results were fairly good. the advantages and disadvantages of the lower and upper trapezius myocutaneous flaps as well as the pectorlis major myocutaneous flap were discussed.
OBJECTIVE To introduce the method using the gracilis myocutaneous flaps to repair of vulvar defect after radical vulvectomy. METHODS The gracilis myocutaneous flaps were applied in 4 cases with vulvar carcinoma which located vestibule of vulva and bulk, and the carcinoma was large after radical resection to repair vulvar defect simultaneously. RESULTS The incision of 3 cases was healing by first intention, and 1 case with type II diabetes mellitus was healing by second intention. After followed up 3-6 years, 1 case was recurrent in 2 years after operation, 3 cases were survival without complication. CONCLUSION Vulvar reconstruction with the use of gracilis myocutaneous flaps in radical vulvectomy could markedly decrease the rate of complication.
ObjectiveTo investigate the clinical anatomy and application of free profunda femoral artery pedicled chimeric myocutaneous perforator flap in the defect reconstruction after radical resection of tongue carcinoma. MethodsBetween April 2011 and January 2016, 44 cases of tongue carcinoma underwent radical resection, and tongue defects were reconstructed by free profunda femoral artery pedicled chimeric myocutaneous perforator flaps at the same stage. There were 40 males and 4 females, with a mean age of 46.3 years (range, 32-71 years). The pathologic type was squamous cell carcinoma, which involved the lingual margin in 24 cases, the ventral tongue in 17 cases, and the mouth floor in 3 cases. According to Union for International Cancer Control (UICC) TNM staging, 16 cases were rated as T4N0M0, 11 cases as T4N1M0, 9 cases as T3N1M0, and 8 cases as T3N2M0. The course of disease ranged from 1 to 22 months (mean, 8.6 months). The size of perforator flap ranged from 8.5 cm×4.0 cm to 12.0 cm×6.5 cm, and the size of muscle flap ranged from 4.0 cm×3.0 cm to 7.5 cm×5.0 cm. The adductor magnus myocutaneous flap with a pedicle of (8.3±0.5) cm was used in 11 cases, and the gracilis muscle myocutaneous flap with a pedicle of (8.1±0.8) cm was used in 33 cases. The donor sites were sutured directly. ResultsAll 44 perforator flaps survived uneventfully, and the donor site healed well. The patients were followed up for 12 to 40 months (mean, 23.8 months). The reconstructed tongue had good appearance and function in swallowing and language. No local recurrence was found. Only linear scar was left at the donor sites. ConclusionThe free profunda femoral artery pedicled chimeric myocutaneous perforator flap can be harvested in various forms, and is an ideal choice to reconstruct defect after radical resection of tongue carcinoma.
It is difficult to repair the pulp defect of finger with good function. Here reported two cases of pulp defect of the thumb which were repaired with free palmris brevis musculo-cutaneous flap. The flap was designed as the following: taken the line crossing the pisiform and metacarpo-phalangeal joint of the little finger as the longitudinal axis of the flap. The proximal end of the flap was at the level of pisiform and the distal end was the distal transverse palmar crease. The radial border was the radial side of the palmris brevis and ulnar border was the ulnar edge of the palm. The flap should not be larger than 6.5 cm x 2.5 cm. The flap was dissected with proper ulnar vessels and the accompanying arterial branch and superficial branch of the ulnar nerve. The flap was transferred to repair the pulp defect of the thumb. The vessels were anastomosed with the radial artery and cephalic vein at the snuffbox. The nerves were sutured to the digital nerve. Three months after operation, the defect was healed and the sensation of pulp was recovered. The donor area was painless and without sensation disturbance. The motion of the little finger was normal. The function of the thumb was restored. It was concluded that the palmaris brevis musculocutaneous flap is one of the best donor region to repair pulp defect of thumb.
OBJECTIVE: To investigate the location of transverse rectus abdominis musculocutaneous (TRAM) flap perforators on abdomen skin and the peak systolic flow velocities of the perforators. METHODS: A series of 94 consecutive patient’s TRAM flap perforators were detected by color-flow duplex Doppler scanning peroperatively. Perforator locations were tabulated on the abdomen skin according to their vertical position relative to the umbilicus and their lateral location relative to the abdominal midline. RESULTS: The perforators on both left and right side of TRAM flap were quite not symmetry. The peri-umbilical region contained 81.1% of the perforators. All perforators were detected with peak systolic flow velocities ranging from 5 to 81 cm/s. CONCLUSION: The preoperative color-flow Doppler localization of TRAM flap perforators improves the surgeon’s ability to design the flap in order to capture the dominant vessels, and select single- or double-pedicle and free TRAM flaps based on each patient’s individual characteristics.
Objective To introduce the myocutaneous flap in blepharoplasty and summarize its clinical efficacy. Methods Between January 2013 and March 2016, 1 560 patients underwent blepharoplasty with myocutaneous flap. Of them, 158 patients were followed up over 6 months and included in the study. There were 18 males and 140 females with the average age of 23.4 years (range, 18-35 years). The unilateral side was involved in 13 cases and bilateral sides in 145 cases. The patients had narrow double eyelid, shallow double eyelid, single eyelid, bloated upper eyelid, and upper eyelid skin relaxation. During operation, the tissue between the orbicular muscle of eye and the tarsus was trimmed layer by layer; the orbicularis oculi muscle, capillary network, and the front fascia of tarsus were retained, and the full-thickness skin, muscle, and the front fascia of tarsus were sutured by anatomical apposition. Results Incision healed at stage I. All patients were followed up 6 months to 2 years (mean, 8.3 months). During follow-up period, shallow or extinctive double-eyelid line was observed in 9 cases (12 eyes), and satisfactory results were achieved after trimming front fascia of tarsus and suturing. Good clinical results were obtained in the other patients, who had natural and coherent double eyelid without obvious scar or depression at resection margin. Conclusion Myocutaneous flap for blepharoplasty has many advantages of fast recovery, little wound, light swelling, permanent effects, and good appearance.
Objective To introduce the treatment experiences about the skin-sparing mastectomy and immediate breast reconstruction. Methods The skin-sparing mastectomy and immediate breast reconstruction by using transverse rectus abdominis myocutaneous （TRAM） flat were performed in 10 patients with early-stage breast cancer from May 2008 to December 2011 in our hospital. The patients’ data were retrospectively analyzed. Results There were postoperative complications after skin-sparing mastectomy and immediate breast reconstruction， including TRAM flat necrosis in 1 case， papillary necrosis in 1 case and fat necrosis in the reconstructed breast with oxter wound infection in 1 case. There was no incision hernia of abdominal wall or necrosis of all TRAM flat in any case. The patients’ satisfaction that evaluation for the breast shapes of reconstructed breasts was very satisfaction in 5 cases， part satisfaction in 4 cases， and dissatisfaction in 1 case， respectively. Conclusions Because of the minimal access approach and good breast shape， the skin-sparing mastectomy and immediate TRAM flat breast reconstruction is a safe and effective way for treating early-stage breast cancer.
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.
