BACKGROUND Many techniques have been reported for the correction of inverted nipples. However, the conventional methods may be insufficient, especially for moderate to severe inversions. We propose a modification of Elsahy's method and report satisfactory results. METHODS A single-institutional retrospective review was performed for all patients who(More)
PURPOSE There have been numerous attempts to use pharyngoesophageal reconstruction to restore swallowing function. Much controversy exist over reconstruction after total or partial pharyngectomy, and there is also debate over whether to continue with the reconstructive procedure with a narrow strip of remnant mucosa or complete it after total pharyngectomy.(More)
Soft tissue filler injection has been a very common procedure worldwide since filler injection was first introduced for soft tissue augmentation. Currently, filler is used in various medical fields with satisfactory results, but the number of complications is increasing due to the increased use of filler. The complications after filler injection can occur(More)
BACKGROUND Although botulinum toxin type A has been shown to inhibit the formation of hypertrophic scars, little is known about the underlying mechanisms of action. Studies have reported that botulinum toxin type A is able to inhibit fibroblast proliferation and transforming growth factor (TGF)-β1 expression; therefore, in this study, the authors evaluated(More)
It is generally accepted that the developmental deficiency of the unilateral perinasal skeleton, cartilages, and skin originates from the secondary cleft nasal deformity. To date, numerous attempts have been made to correct these deformities, but no clinical data are available about the simpler, comprehensive, and patient-customized methods for correction(More)
Nevus comedonicus is a type of hamartoma that arises from a developmental anomaly of the mesodermal part of the pilosebaceous gland. In most cases of nevus comedonicus, an acne-like skin condition develops. Repeated inflammation can cause a morphological change to the cyst, papule, to abscess. We experienced a case of congenital nevus comedonicus, which led(More)
Nasal bone fractures are the most common type of facial fracture. Closed reduction has been used as the standard treatment modality for nasal fractures for many years. In cases of nasal fracture with lacerations at the fracture sites, bioabsorbable/metallic plate or interfragment wire fixation can be used with accurate alignment through the openings created(More)
BACKGROUND There have been few studies of the action of epinephrine injected into scalp tissue, or whether the action of epinephrine differs according to vascular anatomy within the same surgical field. Effective perioperative control of bleeding is critical during hair transplantation due to its time-consuming nature. OBJECTIVE To identify the(More)
Breast implants used for augmentation mammoplasty or breast reconstruction could rupture from various causes such as trauma or spontaneous failure. The objectives of this study were to investigate the relationships between the causes of implant rupture and the degree of capsular contracture, and then to evaluate the relative efficacies of specific signs on(More)
The purpose of this study was to devise an expanded ischemic flap model and to investigate the role of AMD-3100 (Plerixafor, chemokine receptor 4 inhibitor) in this model by confirming its effect on mobilization of stem cells from the bone marrow. Male Sprague-Dawley rats were used as an animal research model. The mobilization of stem cells from the bone(More)
