A new method for clitoroplasty in male-to-female sex reassignment surgery.

Sex reassignment surgery has proved to be the best resolution for primary transsexuals. In 1980, Dr. Rubin stated that preservation of the glans to reconstruct the clitoris in male-to-female sex reassignment surgery gave good cosmetic and functional results. In his series, Rubin used the corpus spongiosum as the vascular pedicle of the neoclitoris, but urine leakage is a complication. From 1988 to the present, the dorsal portion of the glans penis with the dorsal neurovascular pedicle has been used here for clitoroplasty in nine male-to-female primary transsexuals. All neoclitorides survived well, with good preservation of light touch and sexual sensation. No urine leakage has occurred. Six patients who were followed reported sexual satisfaction.

[Clinical application of Chinese forearm flap: 5-year review].

Twenty-nine patients treated with the Chinese forearm flap from 1985 to 1989 were reviewed. This flap was used for soft tissue defect reconstruction in 19 cases, and phallus reconstruction in 10 patients. There were two cases of total flap failure and two cases of partial failure. Twenty cases used sensory flaps. Donor site complications included partial loss of the skin graft with tendon exposure in one patient (3.4%), limitation of range of movement of the wrist joint in one case (3.4%), and paresthesia over the radial site of the hand in 12 patients. On functional evaluation, 20 patients demonstrated no significant loss of strength in the donor extremity.

[Fleur-de-lis flap].

An Abbe flap with lateral vermilion extension (Fleur-de-lis flap) was used in four cases of secondary deformity of lip and palate with tightness and thinness of upper lip following primary cleft lip and palate surgery. The Abbe island flap was converted into fleur-de-lis flap with extensive mucosal wings to improve the fullness of the upper lip. The results were considered to be superior to those obtained by using an Abbe flap only. The balance between the lips was also improved. The technique is recommended in patients of secondary deformity of cleft lip with severe shortage and thinness of the lip vermilion.

Squamous cell carcinoma of the lip.

We reviewed 39 cases of squamous cell carcinoma of lip from 53 consecutive patients with carcinoma of the lip. The retrospective review includes age, location, risk factors, TNM classification, histologic differentiation, treatment methods, recurrent disease, site of recurrence, and follow-up status. Results reveal prognosis is related to original tumor size, local recurrence, and presence of cervical metastasis. Aggressive surgical treatment is recommended for identifiable poor prognostic lesions and includes surgical excision, prophylactic suprahyoid neck dissection, and possible radical neck dissection.

Prophylactic antibiotics in surgical treatment of axillary hyperhidrosis.

A randomized, prospective, double-blind study designed to compare the effectiveness of the use of cloxacillin with the result of nontreatment in patients undergoing surgical intervention of axillary hyperhidrosis was conducted from August 1987 to October 1987 at the Veterans General Hospital, Taipei, Taiwan. Forty-two patients were enrolled in this study. Fifty wounds (25 patients) were control subjects, and 34 wounds (17 patients) received cloxacillin. The positive bacterial culture rates of the tissues and draining from patients in the treatment group compared with the control group was statistically significantly lower (p less than 0.01). No significant differences presented in relation to age, sex, complication rate, fever index, and length of hospital stay. Prophylactic antibiotic is of no value in elective surgical intervention of axillary hyperhidrosis.

Reconstruction of anorectal angle after abdominoperineal resection of rectum and anus--an animal model.

Voluntary control of the bowel movements is a social necessity. Lack of control relegates one to psychological debility and the possible need for a permanent colostomy. Anorectal angle plays an important role in fecal continence. In the normal individual, this angle lies in the range of 60 to 105 degrees. Perineal colostomy, once proposed for patients who had received abdominoperineal resection (APR), has been abandoned because of frank incontinence. This study used a canine model. The anorectal angle, external sphincter, internal sphincter, and the puborectalis were all destroyed after APR. The colon was pulled through the perineal defect. Enteropexy, gracilis muscle transfer, and perineal colostomy were performed to restore the anorectal angle. Barium enema was performed preoperatively and postoperatively. The anorectal angle was reconstructed within normal ranges after abdominoperineal resection of the rectum and anus.

A modified formula of GIK (glucose-insulin-potassium) therapy for treatment of extensive burn injury in dogs.

The effectiveness of a modified glucose-insulin-potassium (GIK) formula, which was derived from the results of a previous study (the maximal glucose disposal rate of 400 mg/M2/min required an insulin infusion rate at 1,200 mU/M2/min and KCl supplement rate at 0.08 mEq/M2/min), was evaluated in the treatment of extensive acute burn injury (EABI) in dogs. Under anesthesia initially with intravenous sodium pentobarbital 35 mg/kg followed by a maintenance dose of 5 mg/kg/hr, a third-degree burn of about 50% of the total body surface was created by acetylene torch over the ventral wall of the chest and abdomen. Cardiovascular parameters including heart rate, mean arterial blood pressure, pulmonary wedge pressure, cardiac index, and cardiac contractility (dP/dt of left ventricular pressure), as well as blood chemical data of pH value and K+ concentration were monitored. The present GIK therapy in EABI dogs effectively prevented a decrease in cardiac function, markedly enhanced cardiac function, steadily prolonged cardiac enhancement, and safely avoided hypoglycemic attack.

Tissue expanders in soft tissue reconstruction.

In order to reconstruct soft tissue defects, plastic and reconstructive surgeons have developed various means that range from the simplest skin grafts to the most complex transfer of microvascular free flaps, but there are no other more than tissue expansion can achieve good results in both aesthetic and functional aspects. From Oct. 1986 to Oct. 1988, tissue expansion was used in seven male and six female patients aged from 11 to 40 years, with a mean of 25. They were divided into 3 groups according to the location of defects: head and neck, 6 cases; trunk, 2 cases; and extremity, 5 cases. Seven cases had successful results and 6 cases failed: one due to infection, one due to leakage of bag and another 4 due to expander extrusion. We know that tissue expansion is a relatively new technique. It expands the healthy tissue immediately adjacent to the defects and provides tissue with near perfect color match, texture, sensation and hair distribution for reconstruction. Although high risk of failure was noted (6 in 13 cases), it still deserves trying for its reasonable aesthetic and functional results.
