An anatomic examination of the suprascapular flap.

To investigate the potential utility of a suprascapular flap, the authors examined dissected cadavers to identify the ramification of the suprascapular artery, and directly injected 2.5% patent blue dye to observe the distribution of its cutaneous perforators. Results indicate that a suprascapular flap is not practicable. The branching pattern of the suprascapular artery from the subclavian artery varies widely, making dissection of the vessels highly problematic. Moreover, no constant presence of cutaneous perforators from the artery could be identified in either the suprascapular fossa or the shoulder.

Retrograde intra-arterial infusion of prostaglandin E1 and heparin for the no-reflow phenomenon after oromandibular reconstruction with a free fibular flap.

The authors encountered a patient with a tumor of the floor of the mouth in whom the no-reflow phenomenon occurred after excision of the lesion and the mandible, followed by reconstruction using a free fibular flap. A catheter was inserted retrogradely from the point where the peroneal artery had been ligated at the time of flap preparation. Continuous intra-arterial infusion of prostaglandin E1 and heparin was performed, and the flap survived. This method salvaged free flaps subject to the no-reflow phenomenon.

Chondroid syringoma of the orbit.

Chondroid syringoma is a rare subcutaneous tumor that mainly affects the face and the neck. The authors present an occurrence in the orbit, which they believe to be the first reported at that site. Computed tomography and magnetic resonance imaging suggested that the tumor had invaded the globe, but at surgery the mass was well circumscribed and did not invade or adhere to other structures. The tumor was resected easily under general anesthesia. Epithelial cells of characteristic appearance within a chondroid matrix were demonstrated histologically. No recurrence has been evident in more than 1 year of follow-up. Most chondroid syringomas are benign, but because several cases have exhibited malignant behavior, periodic observation following complete resection is required.

Monitoring the free radial forearm flap in pharyngo-oesophageal reconstruction.

Monitoring the viability of the free radial forearm flap after pharyngo-oesophageal reconstruction poses technical problems. A method of monitoring using a small island flap elevated distal to the main forearm flap is presented. This monitor flap is easy to elevate. It is placed externally and provides information about the perfusion of the buried reconstruction flap. Postoperative management requires only assessment of tissue colour, turgor, capillary refill and bleeding, as for standard skin flap monitoring.

Bead and wire intermaxillary fixation.

We have developed a method of intermaxillary fixation using beads and wires. This method was effective in mandibular fractures that underwent both open and closed reduction. Our procedure is simple, requires little time, and is inexpensive. We also found several advantages of our technique when compared with the classic arch bar, wire, and eyelet method of intermaxillary fixation.

Functional reconstruction of total lower lip defects with a radial forearm free flap combined with a depressor anguli oris muscle transfer.

Two total lower lip reconstructions were accomplished by combining a radial forearm free flap and a depressor anguli oris muscle transfer. The radial forearm flap was used to reconstruct the inner surface of the lower lip. The bipedicled musculofascial flap, which includes both depressor anguli oris muscles, the depressor labii inferioris muscles, and the mentalis muscles, was elevated onto the chin and sutured superiorly to the modioli to obtain innervated sphincter function. Good results were obtained both aesthetically and functionally. Electromyography revealed almost normal mobility of the depressor anguli oris muscles 6 months after the operation. No drooling was seen during mastication, and no air leakage was observed during puffing of the cheeks. This is an effective procedure for the reconstruction of the sphincter function of the lower lip.

Vermilionplasty using medical tattooing after radial forearm flap reconstruction of the lower lip.

Vermilionplasty using medical tattooing was performed after radial forearm flap reconstruction of the lower lip in 2 patients. This technique is easy to perform in the outpatient setting, does not involve sacrifice of tissue, and results in an acceptable aesthetic outcome. We recommend vermilionplasty with medical tattooing as the procedure of choice after lip reconstruction with a distant flap.

Diffuse and broad podocytic detachment in a case of nephrotic syndrome associated with Kimura's disease.

We report a 49-year-old Japanese male with nephrotic syndrome associated with Kimura's disease. Renal biopsy revealed diffuse podocytic detachment from the glomerular basement membrane (GBM). He had an episode of nephrotic syndrome when complete remission was induced with steroid therapy six years prior to the present admission. However, complete remission of the nephrotic syndrome was not achieved by the steroid on this admission and massive proteinuria (5 g/day) persisted. We suggest that steroid-resistant proteinuria is closely related to podocytic detachment from the GBM and that the production of extracellular matrix by epithelial cells may participate in segmental sclerotic lesions in the patient.

Lid margin reconstruction with an orbicularis oculi musculocutaneous advancement flap and a conchal cartilage graft.

A simple method to reconstruct the midlateral lid margin defect is described using an orbicularis oculi musculocutaneous advancement flap and a free conchal cartilage graft. This method is easy to perform not only in the lower eyelid, but also in the upper one, provides a natural gray line and a stable lid margin without postoperative eversion, and substitutes for the Leone and van Gemert procedure.
