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

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

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

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

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

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 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.

Abstract As a new trial, we used interstitial computed tomography-lymphography (CT-LG) in 10 patients with lower extremity lymphedema (n=20 limbs) at stage 0, 1, 2, or 3 under the International Society of Lymphology (ISL) classification. In all cases, CT-LG, lymphoscintigraphy, and indocyanine green fluorescence-lymphography (ICG-LG) were performed. In the examination of the ascending level of depicted lymphatic vessels, we measured the diameters of lymphatic vessels detected with CT-LG and conducted an image analysis of dermal backflow of lymph (DB). CT-LG had better resolution than lymphoscintigraphy and enabled the clear visualization of lymphatic vessels with a minimum lumen size of 0.7 mm. CT-LG also showed the three-dimensional architecture of the DB, which originated from deep lymphatic collectors via branched small lymphatic vessels. Our findings are quite valuable not only for detailed examinations of lymphedematous sites and for the lymphedema surgery, but also for investigations of the pathogenesis of lymphedema which has not yet been established. We observed that lymphoscintigraphy could show the lymphatic vessels up to the thigh level in all cases, whereas CT-LG enabled the vessels’ visualization up to the leg level at maximum. In conclusion, CT-LG provided adequate and detailed three-dimensional imaging of the lymphatic system in lymphedema patients.

Abstract Osteoradionecrosis (ORN), a well-known complication of radiotherapy in the mandibular bone, is very rare in the cervical spine. The authors report the result of a 3-year follow-up of a 63-year-old female patient with ORN of the cervical spine. The patient had a history of laryngeal carcinoma and was treated with chemotherapy and radiation therapy with a total of 120 Gy. Eight years later, she developed acute, severe neck pain due to cervical spine necrosis. The authors performed vascularized fibular bone graft and posterior pedicle screw fixation to reconstruct her cervical spine. The patient was successfully treated with surgery, and cervical alignment was preserved. She had neither neurological deficits nor severe neck pain at her final follow-up 3 years later. Delaying treatment of ORN may be life threatening, so the early diagnosis of this condition is important for patients who receive radiotherapy. Otolaryngologists and spine surgeons should understand this potential complication to speed diagnosis and treatment as early as possible.

Abstract Many vaginoplasty techniques have been introduced to improve the outcomes of sex reassignment surgery for male-to-female transsexuals. Some vaginoplasty patients still require additional skin grafts, making dilation mandatory to overcome shrinkage. We developed a new vaginoplasty method (called the “pudendal-groin flap”) that uses pudendal-groin flaps. One of this procedure’s advantages is that skin grafts are unnecessary, even for patients with small penises and scrotums. We introduce the procedure here and describe our evaluation of its utility. We retrospectively analyzed the cases of the 15 patients who underwent vaginoplasty using pudendal-groin flaps from May 2010 to January 2016 at our institution. We compared the complications as well as the functional and aesthetic outcomes with those of previous studies. The most common complication was bleeding, which occurred at the corpus spongiosum or while creating a new vaginal cavity. Bleeding can be reduced with more careful hemostasis and dissection. Aside from inadequate vaginal depth in one patient, the incidence of other complications, sexual intercourse, and aesthetic outcomes were acceptable. The pudendal- groin flap is thin and pliable and can create sufficient vaginal depth without skin grafts. The resulting scar is inconspicuous. Our findings suggest that vaginoplasty using the pudendal-groin flap method is feasible.

Abstract Although many surgical centers perform microsurgery routinely in developed countries, performing microsurgery is challenging in resource-poor developing countries, such as Myanmar. With the establishment of educational training programs and the assistance of volunteer plastic surgical teams, local plastic surgeons can learn the techniques of microsurgery and apply them clinically. The purpose of this study was to establish baseline data and define the challenges of performing microsurgery in Yangon General Hospital, Myanmar. Sixty-four patients underwent reconstruction with free flaps from January 2015 to January 2018. All clinical records of these cases were assessed. The number of free flap reconstructions performed increased from 11 in the first year to 24 in the third year. The anterolateral thigh flap was the most commonly used (42%). The most common sites of reconstruction were mandible and intraoral defects. Total flap survival occurred in 58 of 64 patients (89%). The total salvageable flap rate for revision surgery was 66.6%; the successful revision rate was highest in 2017, with fewer complications. The flap salvage rates increased and the operative duration decreased as clinical experience improved. Establishing a microsurgical center requires a strong multidisciplinary team, clinical experience, continuous learning, sensible clinical application, and effective interdepartmental and intradepartmental cooperation.

Abstract Gender dysphoria is a condition in which a discrepancy between biological sex and gender identity causes distress. Many female-to-male transsexuals (FTMTS) are uncomfortable with female breasts. Chest wall contouring surgery is effective for obtaining a male-type chest, reducing mental stress, and increasing sexual satisfaction in such cases. At the Okayama University Hospital Gender Center, we have obtained positive results using an algorithm to determine the most appropriate surgical method for chest wall contouring in FTMTS patients. However, serious complications requiring reoperation, such as hematoma, may still occur. Postoperative hematomas were found in 15 (4.18%) of 358 FTMTS patients who underwent chest contouring surgery at our hospital between 2006 and 2018. Postoperative hematoma was examined retrospectively. The median time to the onset of hematoma was 7 (6-12) h after the initial surgery. The main blood vessels causing bleeding were those in the head-side skin flap region where visual confirmation was difficult and the perforator vessels from the pectoralis major muscle. Intraoperative bleeding and the operation time had a significant impact on the onset of postoperative hematoma. This is the first retrospective study that investigated the blood vessels and other factors contributing to postoperative hematoma development after chest wall contouring.

Abstract Nosaka, NobuyukiMastectomy is usually the first and most important surgical procedure in female-to-male (FTM) individuals with gender identity disorder. Nipple reduction is also important in the process of reconstructing the chest wall for a more male appearance. If the nipples remain large after a mastectomy, the results may be disappointing to many FTM transsexuals. Nipple reduction enables these individuals to go to the beach or Japanese public baths, where they may go topless in public. We therefore consider that nipple reduction is indicated for all FTM transsexuals who desire it. There are a variety of methods for the reduction of enlarged nipples for women or non-FTM patients, but only a few reports have described the process used to create masculine-appearing nipples for FTM transsexuals. We developed a novel technique called the Eryngii method for creating male-like nipples using a 4-mm diameter dermal punch knife. The name of the method refers to the Eryngii king trumpet mushroom, which the nipple resembles after the surgical process. The main strength of this method is that it permits the creation of ideal nipples without difficulty. Here we introduce the technique and discuss our history of surgical methods for nipple reduction, including improvements and elaborations.

Abstract Ventriculitis is a rare, serious complication of neurosurgery. A 59-year-old man who had undergone a craniotomy for a paranasal adenocarcinoma, developed a right frontal cystic lesion. We performed a bifrontal craniotomy to remove the lesion. The dura was repaired with non-vascularized free fascia lata in watertight fashion. Ventriculitis occurred 3 days postoperatively. Ventricular drainage, craniectomy, and endoscopic irrigation were undertaken to remove an abscess. The dura and the resection cavity were reconstructed using a vascularized anterolateral thigh adipofascial flap. His symptoms disappeared, indicating that endoscopic irrigation and reconstruction can effectively address ventriculitis even in patients in critical clinical condition.

Abstract The importance of a well-fitted, comfortable brassiere to overall quality of life after breast reconstruction has not been evaluated. Our aim was to determine the impact of a semi-customized brassiere on patients’ health-related quality of life after breast reconstruction. The subjects were prospective patients with mastectomy who were to undergo immediate or delayed breast reconstruction at our hospital. After surgery, a professional bra fitter sized each patient for a semi-customized brassiere and provided follow-up consultations. A self-reported questionnaire on breast aesthetics, postoperative pain, and satisfaction was used to assess the primary outcomes. Data were prospectively collected at baseline (before surgery) and at 1, 3, 6, and 12 months after surgery and analyzed. Forty-six patients (50 breasts) were included in the analysis. Consistent wearing of the brassiere reduced pain (p<0.05), with good overall satisfaction (p<0.001). Aesthetic scores on breast shape and size were higher with than without the custom brassiere at 3 months (p=0.02) and 6 months (p=0.03) after surgery. Wearing the brassiere reduced anxiety at all time points of measurement. A well-fitting brassiere ensured safety and provided a high degree of satisfaction without anxiety for patients after breast reconstruction.
