A new method of transfer of the nasolabial skin flap, the myocutaneous flap with pediculated guadratus labii superioris muscle was introduced. It was applied in 9 cases mid-face defects with satisfactory results. The applied anatomy and the its operative technique were briefly discussed.
To fix the ligaments, tendons or other transplantation materials by passing through bone channels was commonly used and a relialde method in the reconstruction of joint stability. Usually an additional incision was necessary on the side of the outlet of the bone channel, that the screws, plates or U-shaped staple could be applied. An instrument was designed that the steel miniplate could be fixed to the bone by noninvasive method. This technique was applied in 20 cases in which anterior cruciate ligament in 14, posterior cruciate ligament in 4, and collateral ligaments in 2 with carbon fibers. The result was successful in all patients. It was shown that it gave simple manipulation, reliable fixation and no need to have an additional incision, and it could lessen patients’ suffering and lead to satisfactory clinical result.
Since February 1987, reconstruction of the brest by transposition of the contralateral half-brest with myocutaneous flap of pectoralis major muscle was used in 4 cases with successful results. The operation was suitable for those patients having radical mastectomy for early carcinoma of brest, and it was particularly feasible in those patients having benign lesions, trauma or other disorders causing absence of brest, and especially for those patients who had a huse brest of the contralateral side.
Four cases of defects of soft palate followingcomplete resection of soft palate because ofmalignant tumors had been successfullyreconstructed in which 3 patients wereperformed reconstructed with forehead flap andone patient with free forearm flap . All the flapewere survived. The appearance of the soft palateand function of swallowing were recoveredsatisfactorily from reconstruction. The operativetechnique of the reeonstruction of soft palate wasintroduced,and the points of attention ...
Objective To assess the long-time results of reconstruction of the extensor pollicis longus (EPL) function by transfer of the extensorindicis(EI). Methods From August 1978 to March 2003, 46 cases of loss of the EPL function were treatedby transfer of the extensor indicis. Of 46 cases, there were 32 males and 14 females, aged 16-51 years with an average of 36 years; there were 24 cases of oldtraumatic rupture and 22 cases of secondary rupture. The disease course was 2 days to 5 months, averaged 74 days. A specific EIEPL evaluation method (SEEM) wasused to measure the EPL function after transfer.Results Fortyone cases were followed up 9 years and 3 months on average (7 months to 23 years). Based on the SEEM, the results were excellent and good in 39 of 41 patients. The elevation deficit and combined flexion deficit were 0-2.2 cm (1.8 cm on average) and 0-3 cm (1.6 cm on average); the independent extension deficit was 0°-8° (5° on average). Conclusion Restoration of the extensor pollicis function by transfer of the extensor indicis is an effective and safe treatment option and the SEEM is a valid method for assessing EPL function.
From 1979 to 1994, reparative and recons tructive surgery were used to repair the war injuries of skins, bones, blood vessels and nerves of the limbs in 800 cases. A systematic clinical study was carried out. Many new operative methods were used and the results of treatment were good. Innovations and modifications were made in technique. In 120 cases of warin juries having soft tissues defects including skin and muscles, various tissue transplantations were used with the hope to accomplish onestaged repair of the defect and reconstruction of motor function of muscle. To those infections of bone and joint in war injuries, following early eradication of infected focus, transplantation of musculocutaneous flap or omental graft was immediately carried out with the aim to obtain primary healing of the wound. In the treatment of bone defects from war wounds with loss of skin and muscles, the vascularized skeletocutaneous graft was used. In the treatment of 150 cases of injury of peripheral nerve from forearms, the result of good to fair rated 68.8 percent for upper extremity and that for lower extremity, it was 62.2 percent. Following the early repair of 500 cases of injury of peripheral blood vessels, the patency rate of the blood vessel was 90 percent. The result following by pass vascular graft in the treatment of forearms injury of blood vessels even with very poor local condition was still very successful.
OBJECTIVE: To observe the strength of thigh muscles after reconstruction of anterior cruciate ligament by autogenous bone-patellar tendon-bone graft. METHODS: Twenty-three patients, 9 males and 14 females, were followed up one year after reconstruction of the anterior cruciate ligament with autogenous bone-patellar tendon-bone graft. Through arthroscope, no intra-articular derangement was found. The strengths of isometric and isotonic contractions of the quadri ceps and the hamstrings muscles of the affected and contralateral thighs were recorded. RESULTS: The donor side for autogenous bone-patellar tendon-bone graft showed significant decrease (P lt; 0.01), but no effect on that of the hamstrings muscle(P gt; 0.05). CONCLUSION: To reconstruct the anterior cruciate ligament, harvest of the bone-patellar tendon-bone graft as a reparative material may markedly lower the strength of the quadriceps femoris muscle.
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 choose suitable free flaps for reconstructing headand neck defects caused by tumor resection. Methods A retrospective analyses was made in 86 cases of head and neck defects treated with four kinds of free flaps between January 1999 and January 2002. The head and neck defects were caused by tumor resection. The locations were oral cavity (n=32), hypopharynx (n=27), mandible (n=12), skull base (n=5), scalp and skin (n=6) andmidface(n=4). The donor sites of free flaps included the rectus abdominis (n=32), anterolateral thigh (n=10),jejunum (n=25), fibula (n=11), latissimus dorsi (n=4), forearm (n=3) and scapula (n=1). The sizesof the cutaneous/musculocutaneous flaps ranged from 4 cm×5 cm to 14 cm×24 cm. The lengths of the fibula were 4-16 cm,of jejunum 9-20 cm. Results The overall free flap success rate was 92% (79/86). Of 32 oral cavity defects, 22 were reconstructed by rectus abdominis (69%) and 10 by anterolateral thigh flaps (31%). Of 27 hypopharyngeal defects, 25 were restored by jejunum flaps (93%). Eleven of 12 mandibular defects were reconstructed by fibula flaps(92%). Four of 5 defects of skull base were reconstructed by rectus abodominis flaps (80%). The free flaps of rectus abodominis, anterolateral thigh, jejunum and fibula were most frequently used, accounting for 91%(78/86) of all flaps in head and neck defect reconstruction. Conclusion Although head and neck defects represent a complicated spectrum of subsites and loss, these four freeflaps can manage most reconstruction problems.
From Nov. 1988 through Apr. 1994, 78 cases with laryngocarcinoma underwent laryngectomy and laryngeal reconstruction by the use of transfered cervical skin. Three to six months after operation, all patients were subjected to direct or indirect laryngoscope. It was found that the keratinized of layer of the transfered skin tended to be thining out, and that hair had grown in one case. With the followup ranging from 3 months to 5 years,the results were good. All patients following the reconstruction of larynx could phonate, swallow and breath. Postoperatively, 32 patients were alive for 3 years, 2 patients died from recurrence of laryngocarcinoma. The complications included laryngeal fistula in 6 cases and laryngostenosis in 2 cases. The cause as well as the prevention of complications were discussed. It was suggested that thetransfer of cervical flap was feasible for laryngeal reconstruction.
