Abstract

The first case of sex reassignment surgery (SRS) in our hospital was performed in January 2001; as of February, 2005, 4 cases of MTF-SRS had been performed. In the 2 most recent cases, we used penile and scrotal skin flaps to avoid complications. The depth and width of the new vagina was made to be adequate for sexual intercourse. Future attention should be focused on devising a surgical technique that will help prevent the complications of partial necrosis of the epidermal skin and wound dehiscence. Although ours is only an initial experience, we describe our surgical technique herein.

Abstract We treated a case with left tibial adamantinoma by use of a contralateral fibular osteoadiposal flap. The donor site of conventional fibular osteocutaneous flap must be covered with a skin graft because if we close the donor skin defect directly, compartment syndrome might occur. We were able to close the donor skin defect because this combined type flap included only a small monitoring skin paddle. We present herein the utility of the osteoadiposal flap and show the value of a skin-sparing approach with a minimal aesthetic defect.

Abstract

To date, many techniques have been reported for vaginoplasty in male-to-female trans-sexual (MTFTS) patients, such as the use of a rectum transfer, a penile-scrotal flap and a reversed penile flap. However, none of these procedures is without its disadvantages. We developed a newly kind of flap for vaginoplasty, the M-shaped perineo-scrotal flap (M-shaped flap), using skin from both sides of the scrotum, shorn of hair by preoperative laser treatment. We applied this new type of flap in 7 MTFTS patients between January 2006 and January 2007. None of the flaps developed necrosis, and the patients could engage in sexual activity within 3 months of the operation. The M-shaped flap has numerous advantages: it can be elevated safely while retaining good vascularity, it provides for the construction of a sufficient deep vagina without a skin graft, the size of the flap is not influenced entirely by the length of the penis, and it utilizes skin from both sides of the scrotal area, which is usually excised.

Abstract

Between January 2001 and December 2007, we performed vaginoplasty as sex reassignment surgery in a total of 14 male-to-female transsexual (MTFTS) patients [1]. Several complications occurred such as partial flap necrosis, rectovaginal fistula formation and hypersensitivity of the neoclitoris. Just after the operation, some patients feel that their penises still exist, but by several weeks postoperatively, this sensation has disappeared. Herein we report a case of MTFTS in whom the sensation of a phantom erectile penis persisted for much longer.

Abstract

We treated 2 different types of intersexual patients who underwent a vaginoplasty with the pudendal-thigh flap. One was a female with testicular feminization syndrome for whom we reconstructed the total vagina with a pudendal-thigh flap, and the other was a female with an adrenogenital syndrome for whom we enlarged the introitus of the vagina with the same approach. There were no complications such as a flap necrosis. In addition, there was no stricture of the neo-vagina and no urinary problem.

Abstract

The first operative procedure in sex reassignment surgery (SRS) for female-to-male transsexuals (FTMTS) is mastectomy. This procedure includes the removal of mammary tissue, removal of excess skin, and reduction and proper repositioning of the nipple and areola complex. We have performed mastectomies in over 120 patients since January 2001 and want to describe the operative procedures we have developed. We classified our patients into 3 groups according to the patient's breast volume and the degree of ptosis, and we selected the operative procedure that was suitable for each group. At present all costs for SRS are assumed by the patient in Japan. If the FTMTS patient undergoes the entire series of SRS operations, he has to pay more than 3,000,000 yen. Thus the surgeon should select the proper operative procedure so that the patient can avoid unnecessary additional operations. We describe herein the techniques and the strategy for performing mastectomy in FTMTS.

Abstract Churg-Strauss syndrome (CSS) is a granulomatous necrotizing vasculitis of unknown etiology associated with bronchial asthma. Despite affecting small to medium-sized vessels, necrosis of the digits due to vasculitis is extremely rare. We report a case of CSS with necrosis of the toe tips. A 37-year-old woman with asthma, who had been diagnosed with CSS 2 years ago, was admitted to our hospital with an exacerbation of CSS. The patient had a high grade fever and complained of abdominal pain and numbness of the lower extremities. Blood examination revealed marked eosinophilia. The fever pattern, abdominal pain and blood eosinophilia showed improvement by combination treatment with prednisolone and cyclophosphamide. However, the color of her right toe tips changed, and necrosis finally resulted despite antithrombotic therapy. Arteriography showed narrowing of the dorsalis pedis artery and of the more peripheral arteries of her right leg. Stump plasty with negative pressure dressing therapy for the toe tips, but not amputation, was done to preserve the leg function. While numbness of the extremities remained, no recurrence of necrosis was seen. Clinicians need to be aware that rare complications of CSS, including necrosis of the digits, can occur.

Abstract In the postoperative treatment of hand surgery, it is important to start exercise therapy as early as possible. In conventional negative pressure wound therapy, the fingers are immobilized by the film dressing covering the wound and hand, thereby preventing sufficient rehabilitation. Here, we devised a bag-type negative pressure wound therapy that makes it possible to start finger exercises almost immediately, and we applied it to 4 patients:one each with hand burns, symmetrical peripheral gangrene, a crush injury accompanied by extensive skin defects and a fingertip degloving injury. The duration of the bag-type negative pressure wound therapy ranged from three to eight weeks, and good granulation was achieved, so that a skin graft was not required. In addition, particularly in the case of the fingertip degloving injury, good nail regeneration was achieved. Except for the case of symmetrical peripheral gangrene, a good range of joint motion with a percent total active motion (%TAM) of 94.7% or more was achieved. Our therapy was performed by inserting the hand into a sealing bag;sufficient exercise therapy was made possible by expanding the bag during rehabilitation.

Abstract Since 2001, we have been performing phalloplasty with a radial forearm free flap as the flap of first choice in female-to-male transsexuals (FTMTS). In the present case, a 22-year-old FTMTS with a negative Allen test, we achieved good results by performing phalloplasty with an innervated island pedicled anterolateral thigh flap using the "tube within a tube" technique, in which the penis and urethra are constructed with a single flap. While phalloplasty with an island-pedicled or free anterolateral thigh flap has been reported previously, the present case seems to be the first of phalloplasty with an innervated island-pedicled anterolateral thigh flap using the "tube within a tube" technique. As compared to a forearm flap, use of an innervated island-pedicled flap may have the following advantages in phalloplasty:1) no need for a microsurgical technique;2) no scars at noticeable sites;3) small functional loss in the flap donor area;4) no sacrifice of major blood vessels. Thus, this technique seems to be a useful clinical alternative for phallic reconstruction.

Abstract Thumb polydactyly is reported to be the most common congenital anomaly of the hand in Japan. The floating type is not particularly rare, accounting for 0.9 to 15% of all cases of thumb polydactyly. However, to the best of our knowledge, there has been only one case of thumb polydactyly with a floating ulnar thumb, reported by Onizuka. Herein, we report a case very similar to that reported by Onizuka. In our case, the vessels feeding the floating ulnar thumb branched from the superficial palmar arterial arch, and X-rays revealed triphalangism. In surgery, we not only reconstructed the morphology of the thumb, but also tried to preserve the sensation in the reconstructed thumb by transposing the digital nerve of the floating ulnar thumb to the radial thumb. In addition to thumb polydactyly, our case also showed hypoplasia of the thenar muscles.

Abstract A palatal augmentation prosthesis (PAP) is used to facilitate improvement in the speech and swallowing functions of patients with tongue resection or tongue movement disorders. However, a PAPʼs effect is limited in cases where articulation disorder is severe due to wide glossectomy and/or segmental mandibulectomy. In this paper, we describe speech outcomes of a patient with an articulation disorder following glossectomy and segmental mandibulectomy. We used a palatal plate (PP) based on a PAP, along with an artificial tongue (KAT). Speech improvement was evaluated by a standardized speech intelligibility test consisting of 100 syllables. The speech intelligibility score was significantly higher when the patient wore both the PP and KAT than when he wore neither (p=0.013). The conversational intelligibility score was significantly improved with the PP and KAT than without PP and KAT (p=0.024). These results suggest that speech function can be improved in patients with hard tissue defects with segmental mandibulectomy using both a PP and a KAT. The nature of the design of the PP and that of the KAT will allow these prostheses to address a wide range of tissue defects.
