OBJECTIVE To provide the anatomical basis for the free paraumbilical flap with sensory nerve. METHODS The morphology, branch and distribution of the inferior epigastric artery and inferior intercostal nerve were dissected and measured in 20 adult cadaver specimens. RESULTS The diameter of inferior epigastric artery at the original point was (2.3 +/- 0.3) mm, and that of its accompanying vein was (3.6 +/- 0.4) mm. The anterial branch of inferior intercostal nerves transversed through their corresponding intercostal spaces of axilla anterior line and ran out of the superficial fascia at the midclavicular line. The lateral anterior branch of the eighth to tenth intercostal nerves ran out of superficial fascia in the range of 0-7 cm above umbilicus and innervated the paraumbilical flap. CONCLUSION It is possible to design sensory paraumbilical flap with the lateral anterior branch of the eighth to tenth intercostal nerve.
Objective To investigate the operative technique and clinical effect of perforator-based flap for repair of glutealsacral skin defects. Methods A new perforator-based flap derived from the gluteal, parasacral and the lumbar arteries was used to repair skin defects ofglutealsacral region caused by trauma or pressure sore. The flap areas ranged from 6 cm×5 cm to 19 cm×11 cm, the diametre of perforating vessel ranged from 1.3 to 2.1 mm,the length of free perforating vessel pedicle ranged from 2.5 to 4.5 cm.Results All the flaps survived andthe wound gained primary healing. All the patients were followed up for 6 to 24months. The colour and texture of the flaps were excellent, the configuration was satifactory and there was no ulcer recurrence. Conclusion This new type of flap is characterized by delicate design, easy dissection, reliable blood supply, nosacrifice of the underlying muscle and no requirement skin graft for donor site closure. It is an optimalmethod in repairing soft tissue defects of the gluteal-sacral region.
ObjectiveTo discuss the effectiveness of using dorsal two wing-shaped advancement flap to reconstruct finger web for treatment of congenital syndactyly.MethodsBetween August 2014 and August 2017, 30 cases of congenital syndactyly were treated, including 18 males and 12 females with an average age of 2.5 years (range, 1.5-5 years). Eight cases were of bilateral hands syndactyly and 22 cases of single hand syndactyly. There were 39 webs of syndactyly (including 1 case of syndactyly of middle finger, ring finger, and little finger). Among them, 11 webs were complete and 28 webs were incomplete. At the dorsum, a flap with V-shaped tip and two wing-shaped pedicle was designed and was just sewed up with an anchor-shaped incision at the palm. Distal end of fingers were separated by serrated flap and were sutured after removal of fatty tissue. In 11 cases with tight skin connection, the defect area at lateral and distal end of fingers was repaired by small pieces of full-thickness skin graft.ResultsAll the flaps survived completely after operation, and no flap necrosis occurred. The skin grafts on the distal side of the finger survived and the wound healed by first intension. All 30 cases were followed up 6-12 months, with an average of 9 months. Postoperative flexion and extension function of fingers were good, and the web depth and width were normal. At last follow-up, according to the Swanson et al. standard, 20 fingers were graded as excellent, 8 as good, and 2 as fair, with an excellent and good rate of 93.3%.ConclusionThe effectiveness of using dorsal two wing-shaped advancement flap to reconstruction finger web for treatment of congenital syndactyly is satisfactory.
【Abstract】 Objective To study the repair and functional reconstruction of oropharyngeal defects after resection of advanced-stage tonsillar cancer, and to select the donor site of appropriate flap. Methods Between October 2000 and February 2010, 13 patients with advanced-stage tonsillar cancer were treated, including 5 cases of high differentiation squamous cell carcinomas and 8 cases of medium differentiation squamous cell carcinomas. There were 11 males and 2 females, with an average age of 53.6 years (range, 39-67 years). According to Union for International Cancer Control (UICC) 1997 standards of oropharyngeal cancer, 1 case was classified as T1N1M0, 2 as T2N1M0, 2 as T2N2M0, 3 as T3N1M0, 2 as T3N2M0, 2 as T4N1M0, and 1 as T4N2M0. The disease duration was 1-8 months with an average of 4.3 months. The tumor invaded lateral wall of nasopharyngeal in 1 case, lateral wall of hypopharynx in 3 cases, epiglottis in 1 case, soft palate in 4 cases, and tongue root in 3 cases. The tumor infiltrating range was from 2 cm × 2 cm to 12 cm × 6 cm. All the 13 cases underwent integrated methods of surgery and postoperative radiotherapy. After resection of tumor by combined neck-mandible-oral cavity approach, pectoralis major myocutaneous flaps were transplanted in 5 cases, forearm free skin flaps in 5 cases, and anterolateral thigh free skin flaps in 3 cases. Results The postoperative pathological results showed 10 cases of cervical lymph node metastasis; 2 cases had local recurrence and 3 cases had cervical lymph node metastasis after postoperative radiotherapy. Neck infection occurred at 5 days after operation in 1 case undergoing transplantation of pectoralis major myocutaneous flap, and vascular crisis occurred at 12 hours after operation in 1 case undergoing transplantation of forearm free skin flap, which were cured after correspondent treatments. The other flaps survived with incision healing by first intention. Second suture was carried out in 1 case undergoing anterolateral thigh free skin flap transplantation because of wound disruption at the donor site. All the patients were followed up 1 to 6 years, with an average of 3.6 years. In 5 cases undergoing pectoralis major myocutaneous flap transplantation, swallowing obstruction and stomatolalia occurred. In 8 cases undergoing free skin flaps transplantation, the appearances of the flaps and the functions of swallowing or speaking were satisfactory, with no dysfunction at the donor site. All the patients returned to normal occlusion, facial appearance and function were normal. According to the direct calculation method, the three-year survival rate was 60.0% (6/10), and five-year survival rate was 37.5% (3/8). Conclusion For the patients with advanced-stage tonsillar cancer, forearm free skin flaps, or anterolateral thigh free skin flaps is the first choice for repairing defect. However, it is better to choose pectoralis major myocutaneous flaps in patients who need large flap and fail to radiotherapy.
ObjectiveTo explore the effectiveness of one-stage metacarpal osteotomy, thumb opponensplasty and polygonal flap reconstruction in the treatment of congenital spade hand deformity. MethodsEight cases of congenital spade hand were treated between January 2013 and March 2017. There were 5 males and 3 females, with an average age of 17.5 months (range, 13-35 months). The clinical manifestations of all the children were congenital spade hand and the affected hand was shorter than the healthy side. The contralateral hand was normal and there was no chest, skull, or facial deformity. The operation was performed with metacarpal osteotomy and thumb opponensplasty, and through the dorsal metacarpal rectangular flap to reconstruct the first web and through rotation of polygonal skin flap to reconstruct thumb web and lateral fold of thumb index nail. The dorsal ulnar and proximal radial segment of thumb were repaired by skin grafting. A vernier caliper was used to measure the first web space and the thumb function was evaluated by modified Tada score. ResultsThe reconstruction of palmar function and the formation of first web were completed in one stage in 8 children. Skin grafting on the dorsal ulnar side of thumb and radial side of index finger survived after operation. All the children were followed up 13-29 months, with an average of 16.1 months. There was no infection, skin flap necrosis, lateral deviation of thumb, scar contracture, or other complications. At last follow-up, there was no significant difference in skin color between the healthy side and the first web of the affected hand. The opening distance of first web space was 3.5-5.0 cm, with an average of 4.2 cm. According to the modified Tada scoring system, the results were excellent in 7 cases and good in 1 case, with an excellent and good rate of 100%. The thumb could grasp and pinch actively, and the palm opposition function was good. ConclusionOne-stage thumb opponensplasty combined with polygonal flap for reconstruction of congenital spade hand deformity can improve hand function very well. The reasonable designing of skin flap can effectively cover important areas, and the operation is safe and reliable.
Objective To summarize the clinical experience in the treatment of refractory decubitus ulcers.Methods From May 1998to March 2005, 22 patients with decubitus ulcers(29 decubitus ulcers) were admitted, whose age was 3692 years. The lesion size was 4 cm×2 cm to 18 cm×15 cm. The locations of decubitus ulcers were the sacrococcygeal region(18 cases), the tuber ischiadicum region (6 cases) and the trochanter major region(5 cases).Enteral nutrientwas given orally and the wound was treated with Wuhuangyihao 8-15 days. Three diabetic patients were injected with insulin. According to patient’s age, ulcer position, ulcer extent and ulcer degree, the flap type was determined. Three wounds were repaired by local flaps, the flap size was 6 cm×4 cm-12 cm×10 cm; 10 by fasciocutaneous flaps, 10 cm×7 cm-20 cm×17 cm; 9 by gluteus maximusmyocutaneous flaps, 13 cm×11 cm-17 cm×14 cm; and 6 by longhead of biceps femoris flaps,11 cm×6 cm-14 cm×7 cm. One was sutured directly. After operation, the patients were placed on airflow suspended bed 7-14 days.Results General nutritional status was improved, hemoglobin was greaterthan 100 g/L, albumen was greater than 30 g/L. Necrosis tissue was removed, granulation tissue turned into fresh, secretion reduced and no redness and swelling occurred in wound. All flaps survived and the wounds healed by first intention. After a followup of 6 months to 5 years, no patient had a recurrence, the color and texture of the flaps were good, the appearance was satisfactory.Conclusion Applying the technique of combined treatment can accelerate the healing of refractory decubitus ulcers and improves the success of operation.
