The purpose of this study was to assess the effectiveness free tissue transfer for treatment advanced mandibular osteoradionecrosis (ORN) in head and neck cancer patients.We reviewed 29 patients who were treated ORN by radical resection reconstruction with flaps at our institution. All had either failed respond conservative treatment, including hyperbaric oxygen therapy debridement or pathological fracture due ORN.Twenty-four vascularized bone (17 fibula, five iliac, two scapula), four...
We have investigated the photochemistry of dimethyl disulfide (DMDS) and glutathione (GSSG) in solution upon ultraviolet (UV) excitation comparison to L-cystine by femtosecond X-ray absorption spectroscopy at sulfur K-edge. For these aliphatic disulfides, very similar differential spectra reveal unequivocally a pair geminate thiyl radicals as single primary reaction product with formation time constant about 100 fs. find size-dependent majority yields for recombination DMDS reforming...
The need for the repair of bone defects has been increasing due to various causes loss skeletal tissue. High density polyethylenes (HDPE) have used as substitutes their excellent biocompatibility and mechanical strength. In present study, we investigated preosteoblast cell proliferation differentiation on adding nano-hydroxyapatite (n-HAp) particles into HDPE scaffold treating HDPE/n-HAp scaffolds with nitrogen (N2) plasma. three-dimensional (3D) were prepared by fused modeling deposition 3D...
Reactive oxygen species (ROS)-sensitive polymer nanoparticles were synthesized for tumor targeting of an anticancer drug, doxorubicin (DOX). For this purpose, chitosan-methoxy poly(ethylene glycol) (mPEG) (ChitoPEG)-graft copolymer was and then DOX conjugated to the backbone chitosan using a thioketal linker. Subsequently, chemical structure DOX-conjugated ChitoPEG (ChitoPEGthDOX) confirmed via 1H nuclear magnetic resonance (NMR) spectra. Nanoparticles ChitoPEGthDOX conjugates have spherical...
This retrospective study was performed to evaluate the clinical impact of diabetes mellitus on prognosis in secondary space infection.Medical records, radiographic images, computed tomography, and microbial studies 51 patients (25 diabetic 26 non-diabetic patients) were reviewed. Patients diagnosed as fascial infections with odontogenic origin underwent treatment at Chonnam National University Hospital, Department Oral Maxillofacial Surgery, from January 2007 February 2009.COMPARED TO...
Objective: This study was designed to analyze the morphometric characteristics of orbital cavity using three-dimensional computed tomography in Asians. Methods: Two hundred seventy-six orbits 142 Asians (74 men and 68 women) were examined compared according age, sex, laterality (right left). Results: Mean values as follows. Orbital depth 49.60 mm from optic foramen orbitale (inferior) 41.32 lacrimal crest (medial). Anterior posterior medial wall heights 17.73 12.76 mm, respectively. Medial,...
To compare the different resorption patterns between resorbable membrane barrier and periosteum after iliac block bone grafting radiographically histologically. Eighteen mature male rabbits weighing from 2.0 to 2.5 kg were used. The recipient site was rabbit skull, autogenous used as material. harvested bones divided in following groups: with preservation of (the group), covered a collagen (Biomesh®, Samyang Co, Korea) removing removal control group). In each experimental group, or donor...
This study was performed to evaluate their 5-year survival rates and identify the factors affecting prognosis of oral cancer patients who had undergone surgical treatment only.Among 130 were diagnosed with malignant tumor oral, maxillofacial, treated in Department Oral Maxillofacial Surgery at Chonnam National University Hospital within a period from January 2000 December 2010, for 11 years, 84 investigated followed up more than 5 years after radical surgery; is primary received only...
Abstract Background The nasal bone is the most protruding bony structure of facial bones. Nasal fracture common fracture. high rate incidence emphasizes need for systematical investigation epidemiology, surgical techniques, and complications after surgery. objective this study to investigate current trends in treatment fractures effectiveness closed reduction depending on severity Patients methods A total 179 patients with a from 2009 2017 were enrolled. Their clinical examination, patient’s...
The incidence of septic arthritis the shoulder joint is increasing as population ages. prevalence infection also because growing use arthroscopy and expansion procedures in shoulder. However, cultures do not always identify all microorganisms, even symptomatic patients. negative ranges from 0% to 25%. Few studies have reported clinical features treatment outcomes culture-negative infections. This cohort study addresses infections nonarthroplasty aimed compare characteristics patients with...
Osteochondroma is a benign tumor that tends to develop in mandibular condyle and coronoid process the craniofacial region. If mass has grown from into infratemporal space with zygomatic arch obstructing access, there are risks associated surgical exposure local resection of these masses.This study reports on case osteochondroma condylar head where we treated excision via preauricular approach 3D analysis. After resection, were no post-operative complications until 8-month follow-up period.In...
I. IntroductionMandibular condylar fractures are common, and their most frequent causes traffic accidents, violence, slip-down, fall-down, sports.Mandibular accompanied by dental trauma or concomitant on the contralateral side.Clinically, complications such as malocclu-sion, anterior open bite, residual pain, mouth opening limitation (MOL), pathological changes in temporomandibular joint (TMJ), osteonecrosis, facial asymmetry, ankylosis may occur due to fractures, appropriate treatment is...
Introduction This study examined the effect of recombinant human bone morphogenetic protein (rhBMP)-2 and β -tricalcium phosphate (β -TCP) on new formation in a rabbit calvarium using rapid prototype titanium cap (RP Ti cap). Materials Methods Eight New Zealand white rabbits were used this study. Hemispherical RP caps (10 mm diameter) implanted subperiosteally calvaria. -TCP was filled control group, rhBMP-2 soaked experimental group. The sacrificed 2 4 weeks after operation. volume pattern...
Fractures of the orbital wall are mainly caused by traffic accidents, assaults, and falls generally occur in men aged between 20 40 years. Complications that may after an fracture include diplopia decreased visual acuity due to changes volume, ocular depression floor height, exophthalmos. If surgery is delayed too long, tissue adhesion will occur, making it difficult improve ophthalmologic symptoms. Thus, early diagnosis treatment important. superior often accompanied skull fractures. Most...
The mucocele on the inferior orbit is infrequent. When there occurrence orbit, infraorbital approach, such as transantral, subciliary approach used commonly. But because of some side effects, authors use transantral intraorally. A 26-year-old woman visited our department with complaint palpable mass. Computed tomography (CT) disclosed cystic lesion left orbit. Surgical to was established bony window opening anterior maxillary wall intralorally. Medpor sheet placed orbital floor after removal...
Closed treatment of mandibular condylar fractures has been used for its indications based on the fracture site, status, and patient age. Posttreatment condyle size is associated with function; however, a few studies have reported bone remodeling patterns volume changes in glenoid fossa after head (CHFs). Therefore, volumetric were analyzed present study, evaluated CHFs. The study included 16 condyles from 12 patients who received closed CHF. After reconstruction 3-dimensional skull model,...
Abstract Background Relapses following orthognathic surgery have been reported to exceed 2% 50%, depending on multiple factors. This study aimed analyze the stability after in patients with mandibular ramus height asymmetry through 3D reconstruction using Cone-beam CT. Methods retrospective cohort investigated who underwent setback bilateral sagittal split osteotomy. Three-dimensional CT scans were taken at three different time points. Evaluation of postoperative involved measuring changes...
