INTRODUCTION: Osteoradionecrosis of the mandible is a relatively common complication in patients with head and neck cancer undergoing radiotherapy or concomitant chemoradiotherapy, characterized by exposure of the mandibular bone either in the mouth or in the facial skin, with no improvement with conservative treatment for six months. The risk factors are radiotherapy in head and neck region, lack of dental prophylaxis before treatment and dental extraction. MATERIAL AND METHODS: Retrospective observational study analyzing incidence and etiologic factors of osteoradionecrosis in 250 patients undergoing radiotherapy or combined treatment of cervicofacial area between 2002 and 2010...

It is assumed that a persistent high level of parathyroid hormone (PTH) might have a relation with bone malignancy. However, there has been no report of osteosarcoma associated with pseudohypoparathyroidism type 1b (PHP1b), which is accompanied by high PTH. PHP1b is the result of resistance to PTH in certain end-organ tissues, especially the kidney; the response in bone is unaffected because it normally expresses stimulatory G protein equally from both parental alleles. A 21-year-old male, presenting with gum swelling at the right mandible, was referred to a dental clinic...

Two dogs of different age groups were presented with the history of oral growth, bleeding, excessive salivation, bad breath, inappetance and dysphagia. Physical examination revealed cauliflower like reddish growth in the gingiva enclosing the mandibular incisiors and canine tooth. Haematology and serum biochemical profiles were within the normal range. Plain radiography revealed extensive growth involving the lower mandible and gingiva. Hence rostral mandibulectomy was performed to excise the tumor mass. The dogs recovered uneventfully after surgery with no difficulty in feeding liquid and semisolid diet...

PURPOSE: To investigate a unique procedure of joined transoral and retropharyngeal high cervical approach (JTRC) without mandibulectomy for treating upper cervical neoplasm involving both C2 and C3. METHOD: A 23-year-old male patient had neoplasma involving C2 and C3 that caused pathologic fracture of C2 and bony destruction of C3. The neoplasm excision and cervical spine reconstruction were performed through JTRC approach without splitting up the mandible. In this approach, there were two surgery windows that could be applied in turns by closing or opening the mouth to gain an ideal exposure...

Dental implants play an important role in postoperative rehabilitation after surgical treatment of oral cancer through the provision of prosthetic tooth replacement. Two major implant prosthesis designs are available: fixed implant-supported prostheses and implant-supported overdentures. We herein report a case of a 16-year-old female patient who underwent alveolar ridge resection for treatment of mandibular gingival carcinoma. Following surgery, oral rehabilitation was attempted using an implant-supported overdenture on a gold bar retainer splinting four implants...

While vascularized iliac crest flap is widely used for mandibular reconstruction, it is often challenging to predict the clinical outcome in a conventional operation based solely on the surgeon's experience. Herein, we aimed to improve this procedure by using computer-assisted techniques. We retrospectively reviewed records of 45 patients with mandibular tumor who underwent mandibulectomy and reconstruction with vascularized iliac crest flap from January 2008 to June 2015. Computer-assisted techniques including virtual plan, stereomodel, pre-bending individual reconstruction plate, and surgical navigation were used in 15 patients...

Anaplastic transformation of well-differentiated thyroid carcinomas at distant metastatic sites is a rare condition. Most cases described in the literature have occurred in the thyroid or regional lymph nodes. We report a case of anaplastic transformation of the follicular variant of papillary thyroid carcinoma in mandibular metastases. A 76-year-old female presented with a painful and enlarging mandibular mass. She had been treated in the past for the follicular variant of papillary thyroid carcinoma. A palliative hemi-mandibulectomy was performed...

Chondrosarcoma is a malignant tumor that is characterized by the formation of cartilage by tumor cells. The tumor is commonly observed in regions where cartilage is already present. In total, 5-12% of chondrosarcomas occur in the head and neck region. However, the occurrence of chondrosarcoma in the mental foramen region is extremely rare. The aim of the present study was to report a case of chondrosarcoma in the mental foramen region. An 18-year-old man presented with a 3-month history of a painless mass over the labial aspect of the right mandible, which was associated with the patient feeling unwell and the loosening of the lower anterior teeth...

We have evaluated the survival of dental implants placed in vascularised fibular flap onlay grafts placed over marginal mandibulectomies and the effects on marginal bone loss of different types of soft tissue around implants under functional loading. From 2001-2009 we studied a total of 11 patients (1 woman and10 men), three of whom had had ameloblastoma and eight who had had squamous cell carcinomas resected. A total of 38 dental implants were placed either at the time of transfer of the vascularised fibular ostoseptocutaneous flaps (nine patients with 30 implants) or secondarily (two patients with eight implants)...

Ewing sarcoma (ES) is a rare, primary malignancy of the bone that occurs mainly in childhood and early adolescence. ES usually occurs in long bones of the axial skeleton. Although uncommon in the jaws, ES at this site is most likely to occur in the posterior mandible. The outcome for patients with localised disease has improved over the decades, due to better combination chemotherapies and better methods of local control. We present the clinicopathologic features and management of a case of ES that developed in the left coronoid process of the mandible of a 31-year-old male...

Mandibulectomy and mandibulotomy procedures are performed with the oscillating saw and the acoustic energy generated during the osteotomies is transferred to the cochlea via temporomandibular joint and air conduction. The aim of this study was to assess the effect of mandibulectomy and mandibulotomy on cochlear function. This study was carried out on 15 patients who underwent at an otolaryngology department of a tertiary medical center between January 2013 and August 2015. The study was designed as a prospective study...

Costochondral grafts are used to replace the mandibular condyle in cases of TMJ ankylosis, and are generally viewed as a gold standard for autogenous reconstruction of the mandibular condyle (Güven, 2000; Posnick and Goldstein, 1993 [1,2]). We report a case where overgrowth of costochondral grafts is seen, resulting in asymmetric mandibular growth and dentofacial asymmetry (Posnick and Goldstein, 1993 [2]). A 17 year old male patient presented with an existing costochondral graft performed due to TMJ ankylosis during childhood...
