Reported herein is a rare case of a solitary fibrous tumor in the buccal cheek mucosa. A 50-year-old man visited the authors' hospital due to a buccal cheek mass whose size had increased.

The Efficacy of Coblator in Turbinoplasty.

Background: Turbinate hypertrophy is one of the common causes of chronic nasal obstruction. In principle, therapeutic guidelines recommend medical treatment. Failure to treat turbinate thickening despite drug therapy may indicate the need for surgery.

Is Rectosigmoid Vaginoplasty Still Useful?

Background: The ideal vaginoplasty must be successful functionally as well as have a natural appearance, and also must retain its functionality and appearance over the long term. Conventional vaginoplasty techniques have functional limitations and are associated with recurrent complications, but rectosigmoid vaginoplasty is known to have a high satisfaction rate due to its functional similarity with the vagina. We conducted the present study to assess the usability of rectosigmoid vaginoplasty over the course of long-term follow-up.

Gender Reassignment Surgery in Human Immunodeficiency Virus-Positive Patients: A Report of Two Cases.

It is believed that surgery on human immunodeficiency virus (HIV)-positive patients is dangerous and should be avoided due to the possibility of postoperative infection of the patients or HIV occupational transmission to the medical staff. We discuss here the preparations and measures needed to conduct surgery safely on HIV-positive patients, based on our experience. We performed sex reassignment surgery on two HIV-positive patients from January 2013 to January 2015.

Cerebral gray matter volume variation in female-to-male transsexuals: a voxel-based morphometric study.

Several studies seem to support the hypothesis that brain anatomy is associated with transsexualism. However, these studies were still limited because few neuroanatomical findings have been obtained from female-to-male (FtM) transsexuals. This study compared the cerebral regional volumes of gray matter (GM) between FtM transsexuals and female controls using a voxel-based morphometry.

Neural activation-based sexual orientation and its correlation with free testosterone level in postoperative female-to-male transsexuals: preliminary study with 3.0-T fMRI.

Purpose: The purpose of this study was to evaluate the brain activation pattern associated with sexual orientation and its correlation with the level of the free testosterone (free T) in postoperative female-to-male (FtM) transsexuals using a 3.0-Tesla functional magnetic resonance imaging (fMRI).

Materials And Methods: Eleven postoperative FtM transsexuals with sex reassignment surgery underwent fMRI on a 3.

Comparison of Prostaglandin E1 and Sildenafil Citrate Administration on Skin Flap Survival in Rats.

Background: Alprostadil and sildenafil are known vasodilators used independently to improve flap survival in animal models. In this study, we investigate whether these agents act synergistically to decrease flap necrosis in rat models.

Methods: After acclimation period, 4 groups of 10 male white rats were given a modified McFarlane skin flap.

Treatment of the Mycobacterium chelonae Infection after Fat Injection.

For recent years, use of autologous fat injection has increased significantly in facial contouring surgery. Along with such increase in use, complications like atypical mycoplasma infection have been also on the increasing trend. The authors report two cases of Mycobacterium chelonae infection that occurred after autologous fat injection.

Problems associated with alloplastic materials in rhinoplasty.

Purpose: Augmentation rhinoplasty using alloplastic materials is a relatively common procedure among Asians. Silicon, expanded polytetrafluoroethylene (Gore-tex®), and porous high density polyethylene (Medpor®) are most frequently used materials. This study was conducted to analyze revisional rhinoplasty cases with alloplastic materials, and to investigate the usage of alloplastic materials and their complications.

Clinical Experience of Sturdy Elevation of the Reconstructed Auricle.

Background: The ear is composed of elastic cartilage as its framework, and is covered with a thin layer of skin. Auricular reconstruction using autogenous cartilage in microtia patients requires delicacy. This paper reports clinical experiences related to elevation of reconstructed ear in the last 11 years.

An introduction to the septal extension graft.

The septal extension graft is a very useful method of controlling nasal lengthening and tip projection, rotation, and shape by fixing a graft to the septum, which leads to a strong supporting structure. Enhancing graft stability is important for better long-term outcomes and minimizing complications or relapse, and even more efficient application of these methods is needed for East Asians who lack enough cartilage to be harvested in addition to possessing a weak cartilage framework. In this paper, the methods for overcoming the drawbacks of the septal extension graft, such as instability, a fixed tip, and insufficiency of cartilage, are presented, and the applications of each method for greater satisfaction with surgical outcomes are also discussed.

Secondary Asian rhinoplasty: lengthening the short nose.

Background: Short nose deformity results from primary short nose, previous rhinoplasty, or trauma. A septal extension graft using rib cartilage can be placed to address this deformity. Indications for this procedure include previously damaged septal cartilage, innate septal issues, saddle nose deformity, skin problems, and secondary deformities of the cleft lip and nose.

Considerations for the management of cryptotia based on the experience of 34 patients.

Background: Cryptotia is a congenital ear deformity in which the upper pole appears buried beneath the mastoid skin. Cryptotia is a common auricular malformation among Asians. The aim of this paper is to examine the surgical techniques for and complications of 34 cryptotic patients.

Correction of the supratip deformity of the nose.

Background: A supratip deformity can develop either congenitally or after a poorly executed rhinoplasty, as a result of fullness or convexity just above the nasal tip.

Objective: In this article, the authors describe the causes of the supratip deformity and present their technique for surgical correction.

Methods: A retrospective chart review was conducted for 62 consecutive patients (24 primary rhinoplasty and 38 secondary rhinoplasty) treated between January 2005 and February 2010.

Reliability of reconstructed breast flap after chemotherapy and radiotherapy in immediate breast reconstruction.

Background: Postmastectomy adjuvant therapy is used to prevent locoregional recurrence and improve overall breast cancer specific survival rates. However, it can adversely affect the cosmetic results of reconstruction. Therefore, the authors examined flap stability and patients' satisfaction with immediate breast reconstruction after adjuvant therapy.

The etiology and treatment of the softened phallus after the radial forearm osteocutaneous free flap phalloplasty.

Background: The radial forearm osteocutaneous free flap is considered to be the standard technique for penile construction. One year after their operation, most patients experience a softened phallus, so that they suffer from difficulties in sexual intercourse. In this report, we present our experience with phalloplasty by radial forearm osteocutaneous free flap, as well as an evaluation of the etiology and treatment of the softened phallus.

Overview of mandibular condyle fracture.

The mandibular condyle is a region that plays a key role in the opening and closing of the mouth, and because fracture causes functional and aesthetic problems such as facial asymmetry, it is very important to perform accurate reduction. Traditionally, there has been disagreement on how to manage fracture of the mandibular condyle. This review explores the misunderstanding of mandibular condyle fracture treatment and modern-day treatment strategies.

Nicolau syndrome after intramuscular injection: 3 cases.

Nicolau syndrome is a rare complication of intramuscular injection consisting of ischemic necrosis of skin, soft tissue, and muscular tissue that arises locoregionally. The characteristic pattern is pain around the injection site, developing into erythema, a livedoid dermatitis patch, and necrosis of the skin, subcutaneous fat, and muscle tissue. Three patients were injected with drugs (diclofenac sodium, ketoprofen, meperidine) for pain relief.

Perceptual speech assessment after maxillary advancement osteotomy in patients with a repaired cleft lip and palate.

Background: Maxillary hypoplasia refers to a deficiency in the growth of the maxilla commonly seen in patients with a repaired cleft palate. Those who develop maxillary hypoplasia can be offered a repositioning of the maxilla to a functional and esthetic position. Velopharyngeal dysfunction is one of the important problems affecting speech after maxillary advancement surgery.

Brain activation in response to visually evoked sexual arousal in male-to-female transsexuals: 3.0 tesla functional magnetic resonance imaging.

Objective: This study used functional magnetic resonance imaging (fMRI) to contrast the differential brain activation patterns in response to visual stimulation with both male and female erotic nude pictures in male-to-female (MTF) transsexuals who underwent a sex reassignment surgery.

Materials And Methods: A total of nine healthy MTF transsexuals after a sex reassignment surgery underwent fMRI on a 3.0 Tesla MR Scanner.

Laparoscopic rectosigmoid flap vaginoplasty.

Various methods have been developed for vaginoplasty, of which the rectosigmoid flap has its own advantages including sufficient increase in the vaginal length and lower incidence of complications such as contracture or strain after vaginoplasty. Laparoscopic operation can greatly minimise the abdominal scar associated with laparotomy and allow cosmetically superior outcomes. Its minimally invasive procedure can also achieve rapid recovery and shorten the duration of hospital stay.

A new method of urethroplasty for prevention of fistula in female-to-male gender reassignment surgery.

One of the primary goals of the phalloplasty for female-to-male transsexuals is to gain the voiding ability in the standing position. However, achieving the competence of urethra, sensation and rigidity of the neophallus is still a significant challenge. Serious complications such as urethral fistula, obstruction and stricture were encountered in this surgery.

Long-term results in the bilateral cleft lip repair by Mulliken's method.

Purpose: To evaluate long-term results in the bilateral cleft lip repair by Mulliken's method, using anthropometric measurements, we assessed the growth of the nose and upper lip after the operation by comparing with those from 30 children without bilateral cleft lip.

Materials And Methods: Forty-four patients had their bilateral cleft lip and nasal deformity repaired simultaneously by Mulliken's method during the period from July 1997 to December 2007. Of these patients, 15 patients had bilateral complete cleft lip, 17 patients had bilateral incomplete cleft lip, and 12 patients had a mixed type of complete and incomplete bilateral cleft lip.

Phalloplasty using radial forearm osteocutaneous free flaps in female-to-male transsexuals.

Gender reassignment operations in female-to-male transsexuals are increasing in number as the skill of phalloplasty develops. The authors are performing phalloplasty 1 year after undergoing mastectomy, reduction of nipples, oophrectomy and hysterectomy in female-to-male transsexuals. The ideal penile reconstruction should be a single-stage procedure, creating a phallus with both tactile and erogenous sensibility, water-tight neourethra allowing for voiding in the standing position, enough bulk with stiffness, and an aesthetically acceptable appearance.

Involvement of ligand occupancy in Insulin-like growth factor-I (IGF-I) induced cell growth in osteoblast like MC3T3-E1 cells.

Growth factors and matrix proteins regulate the proliferation and differentiation of osteoblasts. The insulin-like growth factor (IGF) system comprises IGF-I, IGF-II, and six high-affinity IGF-binding proteins (IGFBPs). IGFs stimulate cell growth in many types of tissue; IGF-binding proteins regulate cellular actions and can affect cell growth.
