Seven cases of the tongue squamous carcinoma afterradical operation were reconstructed by forearm skin flap,medial leg skin flap, pectoral and platismal flaps with onlyone failure. It is very importent to anastomose two veinswhen free vascularized skin flap was applied for reconstruc-tion of the tongue. The distal stump of the medial leg skin flap should beanastomosed with the receptor vessel. Reconstruction of the tongue by pectoral skin flap andplatismal flap have several disadvantages.
Objective To investigate the clinical results of allograft and sural neurovascular flap in repairing calcaneus and skin defects.Methods From February 1996 to December 2002, allograft and sural neurovascular flap were used to repair calcaneusand skin defects in 6 cases. The causes included road accident in 3 cases, strangulation in 2 cases and crashing object in 1 case. The defect locations were at theback of the calcaneus( 1/3, 1/2 and 2/3 of calcaneus in 3 cases, 2 cases and 1case respectively). The flap area ranged from 6 cm×7 cm to 12 cm×17 cm. Results The flaps survived completely in 4 cases; the distal flaps necrosed partly in 2 cases and the wound healed by dressing. The postoperative X-ray films showed that the repaired bone and joint had normal position and the arcus plantaris recovered. After a follow upof 6 months to 3 years all the patients were achieved bone union in allograft and had no complications of absorption, infection and repulsion. The weightbearing and walking functions were restored and the injured foot obtained a satisfactory contour. After 36 months of operation, the sensory recovery of foot occurred. Conclusion The used-allograft iseasy to be obtained and arcus plantaris is easy to recover. The reversesural neurovascular- flap in repairing calcaneus and skin defects has the following advantages: the maintenance of blood supply for injured foot, the less dangerous operation, the simple procedure, the recovery of walking function, and the good appearance and sensation.
An operative technique of vaginal re-construction by labium minimum flap andposterior combined flap was introduced。Clin-ical application in six cases has shown satis-factory result。The author declared that itwas an ideal technique for vaginoplasty withadvantages of obtaining material easily,mini-mal trauma, thin soft and mucoid flap withsensation, high survival rate, and few con-tractures postoperatively。
OBJECTIVE In order to inquire the methods of thumb reconstruction by transferring the index finger with incomplete conditions of nerve or blood vessels. METHODS From April 1987 to October 1997, 6 cases were treated by 3 kinds of operative methods according to the damage type of thumb and complications injures of the rest of hand: 1. transferring the index finger with pedicle without proximal phalanx, 2. transferring the index finger with palmar nerve and blood vessels, and dorsal skin pedicle, 3. transferring the index finger with compound pedicle. RESULTS All 6 cases of thumb reconstruction were successful. Followed up 6 months to 2 years, the pinching and gribing functions in 6 cases were completely recovered, and the sensation were partly recovered. CONCLUSION The operative method of thumb reconstruction had following advantages: Simple operation, high survival rate and certain function recovery. It can enlarge the indications of thumb reconstruction.
Rectus femoris muscle of the lower abdomen was used as myocutaneous flap in the reconstruction of the breast in 4 patients, of which, in 2 cases the reconstruction was carried out immediately following the radical mastectomy for breast cancer by using trancfer of the pedicled myocutaneous flap, and in the other two cases, the vascularized free myocutaneous flap was used 2 months and 5 years after the radical mastectomy, respectively. The vascularized free myocutaneous flaps were survived, however, in the pedicled myocutaneous flap group, the fat of the flaps had liquefaction 23 weeks after operation. The latter were healed after repeated dressings. The external appearance of the 4 reconstructed breasts lookedsattisfactory. The patients wete follwed up for 10 to 18 months, 2 patients hadno ill effects, while the 2 pedicled myocutaneous flaps, in which 1 patient hadbulging of the weakened abdominal wall, and the other had lost from follow up.
OBJECTIVE: To compare the effect of several types of rib rings with intercostal muscles for the replacement of trachea in thorax. METHODS: The surface layer of the third rib of dogs were ripped off and curved into triangular, quadrilateral and polygonal form. These three types of rib rings with intercostal muscles were used to replace a segment of trachea in thorax. RESULTS: The stability of triangular rib ring was very well, but stricture of ring were often happened because of its smaller internal diameter. These stability of quadrilateral rib ring was the worst. The polygonal rib ring presented the biggest diameter and good stability compared to the other two kinds of rings. If silicone tube was supplemented in the polygonal rib ring, the quality of artificial trachea was excellent. CONCLUSION: The rib rings with intercostal muscles are successfully used for replacing the defect of trachea in canine thorax. The polygonal rib rings have the best quality in the three types of rib ring for tracheal replacement.
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.
This paper reported the use of superficial temporal vessels pedicled postauricular island flap for the reconstruction of eye socket. Six cases were treated by this method since 1988 with universal satisfactory results. The disign of the flap was diseribed. The operative procedure was detailed, and the advantages of the flap were evaluated: 1. The donor defect was hidden behind the ear; 2. The flap has a relatively long pedicle, hence easy for distant transfer, and 3. the blood supply was highly reliable.
