  • Parathyroid carcinoma is a rare endocrine malignancy accounting for 0.5% to 4.0% of all cases of hyperparathyroidism and commonly present as hypercalcemia and parathyroid hormone (PTH) elevation. Nonfunctional parathyroid carcinoma does not show symptoms of hyperparathyroidism and only showed a vague indication of being pathologic, even when detected late. The optimal treatment is en bloc resection of the cancer, but frequent local recurrence after surgery has been reported. Adjuvant local treatment such as radiotherapy may improve the likelihood local control in cases with incompletely resected or microscopic residual tumor. The results of this study point to a case of nonfunctional parathyroid carcinoma treated by external beam radiotherapy after en-bloc resection of cancer.

  • Microvascular free tissue transfer technique is widely accepted for reconstruction of extensive soft tissue defects on the extremities. The system of flap based on the subscapular artery and vein provides the widest ways of composite free flaps. The possible flaps that can be harvested based on this single vascular pedicle include the scapular and parascapular skin flaps, the serratus anterior and latissimus dorsi muscular flaps, the lateral scapular bone flap, the latissimus dorsi-rib flap, and the serratus anterior-rib flap. This combined flap is available to mutiple tissue defects or complex defects because it can incorporated with skin, muscle and bone flaps. A strikig advantage is the independent vascular pedicles of each components, which allow freedom in orientation of each components. So, it can be freely applied to any forms of three demensional defects on the upper and lower extremities. The combination of scapular cutaneous flap and latissimus dorsi musculocutaneous flap can be resurfaced for massive cutaneous defects on the extremities. We report the use of the combined scapular and latissimus dorsi free flap in seven patients to reconstruct massive deefcts on the extremities. There was no flap failure and little complications and disadvantages. The anatomy of this flap is reviewed and the indication and advantages are discussed.

  • When covering a skin defect of the finger with a local flap is difficult, a vascular island flap is often used. For a palmar skin defect, it is desirable to add a sensory supply to the flap. This report describes a neurovascular island flap that was used to repair a palmar skin defect, the donor skin coming from the dorsal region of the middle phalanx. This flap is elevated with a vascular pedicle of the palmar digital artery and its dorsal skin branch, including the dorsal digital veins, palmar digital nerve and its cutaneous branches. The advantage of this flap are that it can be transferred with ease and without any tension. No special manipulation is required under a microscope and operation can be performed under a simple nerve-block. There if little possibility that the flap itself undergoes ischemic change or congestion. The disadvantage of this flap are that a skin graft is required at the donor skin site and one palmar digital aretery is lost. We think that this neurovascular island flap is one of the useful methods for skin defects that are difficult to cover with a local flap.

  • We carried out 107 replantations of amputated digits since last 1988. Among them, clean Gillotine amputation was 19 digits, mild crush amputation was 51 digits, severe crush amputation was 28 digits and avulsion type amputation was 9 digits. Vein grafts were used on 24 of these cases. The donor site of the vein graft was the volar aspect of the ipsilateral wrist or lower forearm. The average length of the vein graft was 1.8cm(1.0-3.0cm) and the average diameter of the vein graft was 1.5mm(1.0-2.0mm). Sixty-one of 107 digits were successfully replanted for an 57% success rate. The survival rate of the replantation using the vein graft was 66.7%. We analysed the functional results of the successfully replanted digits according to Nakamura and Tamai's criteria. The functional results of the replantated digits using vein graft were better than that of without using vein graft(more than fair results, 81.2% vs 73.3%). We conclude that the jucidious use of autogenous vein grafts in digital replantation surgery will improve the survival rate and promote the functional result.

  • Despite of technical advances in surgery & other therapeutic modalities five-year survival rates in patients with carcinoma of hypopharynx have remained low. Many techniques have been used to create a structure capable of allowing the passage of food and fluids in an attempt to maintain the anatomy and physiology of the upper digestive system. The development of microsurgical techniques and the concept of mucocutaneous unit has brought about important changes in the reconstruction of cervical esophagus following tumor resection. The one-stage procedure using microvascular anastomosis of free jejunal graft provides physiologic reconstruction of cervical esophagus and has a low morbidity rate as well as a short recuperation time. With free jejunal graft, there is marked improvement in the quality of life and numerous advantages over the previous methods of reconstruction. Reconstruction of esophageal defect after resection of carcinomas of the hypopharynx, and cervical esophagus has traditionally been carried out with deltopectoral, or musculocutaneous skin-lined flaps. A second approach is to reconstruct the defect with the colon or stomach. A more ideal mettled is to repair these defects with mucosa-lined flaps. The authors experienced 35 cases of reconstruction of cervical esophagus after resection of carcinoma of the hypopharynx with free jejunal autograft and one case of secondary repair with radial forearm free flap after failure of initial free Jejunal autograft. Postoperative results were satisfactory in most patients and two patients expired in 8 days postoperatively because of carotid blow out by chronic inflammation.

  • Purpose: Disaster as traffic accident, industrial disaster, high voltage electrical bum and flame burn of extremity have a destructive effect because of the involvement of deep structure. Generally, such injury may result in decreased function or loss of limb. In this study the successful use of the combined scapular/parascapular flap as microsurgical transfer to cover extensive defect of electrical and flame bum is reported. Material and Method: Between January 2000 and June 2001, the combined scapular and parascapular flap was used for the coverage of soft tissue defect for 7 patients were admitted to our department with high voltage electrical bum and flame burn. The recipient site were the wrist joint in 2 cases, the forearm in 1 case, the ankle joint in 1 case, the foot dorsum in 1 case, the heel in 1 case. Result: Flap survival was complete in all patients. The result of flap coverage for these deep wound was successful. Conclusion: The advantages of scapular/parascapular combined flap were coverage of the large defect, easy shaping of the flap to fit the required three dimensional configuration around the joint, non hair bearing skin of uniform thickness, minimal donor site morbidity.

  • In the high radial nerve palsy caused by displaced humeral shaft fracture, radial nerve have to be explored in the fracture site. 5 cases of the ruptured radial nerve at the fracture site of the humerus from January 1993 through January 2005 were treated at first by open reduction and internal fixation with plates and screws fixation and then defective radial nerves were grafted with autogenous sural nerves by microsurgical epineurial and or perineurial neurorrhaphy. At average 30.4 months follow-up, 5 cases were recovered from motor and sensory deficit with solid bony union of the humerus shaft fracture. Authors have confirmed that ruptured radial nerve in the humerus shaft fracture grafted with autogenous sural nerve with microsurgical epineurial and or perineurial neurorrhaphy would be expected good motor and sensory recovery.

  • The auricle is easy to be amputated in the face due to its protruding position. When facial parts are amputated, the mechanism of injury usually involves some form of avulsion, which damages these fragile vessels over a distance and renders them unsuitable for anastomosis. Replantation of the ear remains a challenging problem because of the tiny vessels and the paucity of adequate veins for anastomosis. Reattachment as a composite graft of the total or subtotal amputated ear is unreliable. Microsurgical replantation can be performed in a minority of cases because of technical difficulties and long operation time. In this article, the authors report two case of a successful ear replantation of completely amputated auricle. Only one artery and one vein were anastomosed in first case. In the other case one artery was anastomosed without vein. Instead of venous repair, multiple incision was done with leech application therapy. and the outcome was successful. In spite of the technical difficulties and long operation time, microsurgical replantation of amputated ear is better than other reconstructive method or reattachment without microsurgery.

  • The purpose of this study is to introduce a sensory restoration in reconstructed breast with free TRAM flap to evaluate recovery aspect and recovery quantity. 144 patients underwent breast reconstruction with free TRAM flap by authors and were followed up at the out patient clinique. We discovered that sensory of operated breast was recoverd. We divide the breast into 5 region (upper medial, lower medial, upper lateral, lower lateral, nipple areolar complex) for examining the sensory restoration. Sense of upper medial region & upper lateral region is recovered more quickly than other region. Touch sensation was recovered more quickly than pain sensation, temperature sensation, vibratory sensation. After about 1 year all protective sensation was recovered in all patient. We discovered that severe postop scar and irradiation of breast is related to delayed sensory recovery, age and size of flap is not related to sensory recovery.

  • The extensor digitorum brevis (EDB) muscle island flap is a reliable, safe method for coverage of foot and ankle. There are many variation in approach such as curvilinear, zigzag, L-shaped or vertical longitudinal incision for exposure of the EDB muscle. These approaches use only single incision excluding the distal incision for exposure of the distal tendon. Since dorsalis pedis artery vascular bundle and sinus tarsi branch of the lateral tarsal artery both requires careful dissection, single incision alone may cause not only difficulty in exposure but also skin sloughing at donor site. So we tried to modify the approach into two parallel longitudinal incision, one for dorsalis pedis vascular bundle and the other for sinus tarsi branch exposure. The author treated 9 patient with EDB muscle flap. We used single incision in six patients, and two parallel incision in three patients. All the flap survived. In two parallel incision group, dissection was more easy and rapid. So we would like to suggest that two parallel longitudinal incision approach is better method than the single incision technique for exposure of the EDB muscle flap.
