Distraction osteogenesis (DO) is a reconstruction technique developed in the fields of oral and maxillofacial surgery and plastic surgery, addressing both vertical and horizontal bone deficiencies and enhancing soft tissue volume to facilitate subsequent dental implant placement. In this treatment method, devices are placed to stretch the bone gradually to stimulate the formation of new bone, effectively filling the existing defect to treat maxillofacial deformities or repair posttraumatic injuries. This case report presents an almost 20-year long-term follow-up of jaw defect reconstruction resulting from a gunshot injury, using DO with multiple distractors...

The aim of this study was to analyze the beauty pageants that were held in Korea during the Japanese colonial era (1931, 1940). Through searches of www.google.com and www.naver.com, 3 pageants were found: (1) 1931, Miss Korea, organized by Samchunli (a magazine): Any Korean woman, with the exception of Korean geishas, could apply by submitting her photographs. The number of candidates was 326. Nine Korean judges evaluated the photos of the candidates. Among them, the victor was an 18-year-old Korean woman. (2) 1931 (Oct), Miss Joseon, organized by Osaka Mainichi Shimbun: The candidates were categorized into 2 groups: 10 "internals" (Japanese) and 10 Koreans...

Gold standard method for the treatment of critical-sized bone defects is the autogenous bone grafting procedure. A number of new and potentially useful adjuncts currently are being investigated to enhance the success of bone grafting. We propose to evaluate the effect of the most known and easily obtained 2 biological materials, fat graft and platelet-rich plasma (PRP), on bone graft healing. Twenty-seven New Zealand male rabbits were included in this randomized, controlled study. Two-sided 15-mm diameter bone defects were created in the parietal bones and the bones taken were replaced right-to-left and vice versa with 1 control group, 1 fat graft applied group, and the last one PRP applied group...

This study aimed to comprehensively and quantitatively characterize 3-dimensional (3D) positional and morphological changes of the condyle and glenoid fossa in patients with skeletal Class II malocclusion treated with bimaxillary orthognathic surgery. Twenty eligible patients treated at our institution from January 2016 to December 2021 with more than 12 months of postoperative follow-up were retrospectively enrolled. Radiographic data of cone-beam computed tomography (CBCT) for each patient were collected at 3 stages: 1 week preoperatively (T0), immediately after surgery (T1), and at least 12 months postoperatively (T2)...

Extranodal natural killer/T-cell lymphoma is a distinct subtype of non-Hodgkin lymphoma that originates from natural killer cells or cytotoxic T cells. Its diagnosis is challenging due to the rarity and lack of awareness, especially in cases where osteomyelitis of the jawbone is the initial symptom. This paper reports a case of extranodal natural killer/T-cell lymphoma presenting primarily with oral ulcers. Through analyzing the clinical and pathological characteristics, differential diagnosis, treatment and prognosis, and reasons for misdiagnosis of the disease, this study aims to provide references for clinical diagnosis and treatment...

A 40-year-old man presented with acromegaly, reduction of visual acuity and visual field, and elevated blood sugar. Imaging examinations demonstrated a large sellar adenoma with suprasellar extension that compresses the optic chiasma upward, spreads downward to the sphenoid sinus, and invades the cavernous sinus bilaterally. Random prolactin and growth hormone were beyond the scope of normal. The patient achieved complete shrinking of the adenoma by taking bromocriptine orally. For some kinds of giant mixed growth hormone-prolactin adenomas, surgical treatment is not necessary, and drug treatment can also achieve good results...

Plastic surgery residency programs are offering increasing opportunities for international rotations, recognizing the importance of early exposure and the need to promote better capacity building in host countries. While a greater number of residency programs are offering international opportunities, it is not clear whether applicants are aware of these opportunities based on program websites. The purpose of this study was to determine the availability and ease of access to international rotation information on plastic surgery residency websites...

INTRODUCTION: Mandibular fractures are common in maxillofacial trauma, often requiring surgical intervention for optimal recovery. One critical concern during such procedures is the potential for nerve damage, specifically involving the mandibular canal. This study aims to investigate whether the presence of postoperative mandibular canal discontinuity is associated with an increased risk of nerve damage. METHODOLOGY: A retrospective analysis was conducted on a cohort of 72 postoperative mandibular fracture patients...

Closed treatment of mandibular condylar fractures has been used for its indications based on the fracture site, fracture status, and patient age. Posttreatment mandibular condyle size is associated with mandibular function; however, a few studies have reported bone remodeling patterns and volume changes in the condyle and glenoid fossa after mandibular condylar head fractures (CHFs). Therefore, volumetric changes in the mandibular condyle and glenoid fossa were analyzed in the present study, and bone remodeling patterns were evaluated after mandibular CHFs...

BACKGROUND: Microgenia and the accompanying plump cheeks or hamster-like facial contour are all unattractive appearances among the Asian. Genioplasty with autogenous bone grafting is one of the effective ways to improve microgenia, in which a suitable donor area with less additional damage, lower infection rate, and more excellent effect is crucial. METHODS: Patients who had undergone genioplasty and autogenous external oblique line grafting (G-EOL) were followed up...

Microtia is a congenital and morphological anomaly of one or both ears, which results from a confluence of genetic and external environmental factors. Up to now, extensive research has explored the potential utilization of computational methodologies in microtia and has obtained promising results. Thus, the authors reviewed the achievements and shortcomings of the research mentioned previously, from the aspects of artificial intelligence, computer-aided design and surgery, computed tomography, medical and biological data mining, and reality-related technology, including virtual reality and augmented reality...

Eyelid malignancies are often resected in the entire layer, typically requiring anterior and posterior lamellae reconstruction. Posterior lamella reconstruction has been reported using grafts from the nasal septum, palatal mucosa, and auricular cartilage, which have advantages and disadvantages. The authors performed anterior and posterior lamellar reconstruction using a local skin flap and stripe-shaped anti-helical cartilage with the perichondrium in 3 total defect cases after basal cell carcinoma resection of the lower eyelid...

Squamous cell carcinomas are the most common cancer of the lower lip. In most cases, the tumor is small and occupies less than a third of the lower lip, so the defect created can be closed with a primary suture without altering the esthetics and function of the lower lip. However, there is a percentage of large tumors that affect more than two thirds of the lower lip, in which the primary suture is insufficient to correct the defect created by resection of the tumor. Therefore, these cases require more complex reconstructions using facial locoregional flaps...

Plate fixation to zygomatic arch fractures carries the risk of facial nerve palsy and scarring of the cheek; however, without plate fixation, bone deviation or displacement may reoccur after surgery. Furthermore, zygomatic arch fractures combined with zygomatic body fractures are more postoperatively unstable than single zygomatic arch fractures. Few reports have focused on this combined fracture type, and no consensus has been reached regarding treatment. Because plate fixation for slight deviation of the zygomatic body has little advantage for stabilization, the authors, usually opt for transmalar pinning alone instead of plate fixation at the hospital...

This study aimed to assess the effectiveness of intraoperative computed tomography (ICT) in managing zygomatic complex (ZMC) fractures surgically. A total of 143 patients (84 men, 59 women; average age 37.13 y) undergoing surgical treatment for ZMC fractures participated in this retrospective cohort study, with 72 in the ICT group and 71 in the control group. There were no notable differences in gender, age, time from injury to surgery, and surgical duration between the two groups. The ICT group exhibited significantly fewer surgical approaches than the control group (1...

One of the most common adverse outcomes of an upper blepharoplasty involving double-eyelid surgery is asymmetric upper eyelids due to unbalanced supratarsal folds or a difference in the palpebral fissure height. This study aimed to evaluate the efficacy and safety of transconjunctival levator aponeurosis-Müller muscle complex plication for correcting acquired ptosis following double-eyelid surgery. This retrospective study evaluated 18 patients who underwent transconjunctival levator aponeurosis-Müller muscle complex plication between June 2016 and June 2019 to correct acquired ptosis...

BACKGROUND: The use of Computed Tomography (CT) imaging data to create 3D printable patient-specific devices for radiation oncology purposes is already well established in the literature and has shown to have superior conformity than conventional methods. Using non-ionizing radiation imaging techniques such as photogrammetry or laser scanners in-lieu of a CT scanner presents many desirable benefits including reduced imaging dose and fabrication of the device can be completed prior to simulation...
