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...

INTRODUCTION: The sacrifice of inferior alveolar nerve (IAN) is usual in case of resection of mandibular tumors and is responsible for disabling sensory disorders, drooling and lip incompetence. We report the case of a reconstruction of the IAN by means of an autologous nerve graft after segmental resection of the mandible. OBSERVATION: A 27-year-old man presented with a recurrence of mandibular ameloblastoma. Treatment consisted in segmental mandibulectomy with resection of the IAN...

This study critically assessed the possibility of tumour spread along the inferior alveolar nerve (IAN) and its sensitivity as an intraoperative marker for clear bony margin control in frozen section during segmental mandibulectomy. Fifteen patients with oral squamous cell carcinoma (OSCC) involving the mandible and requiring a segmental mandibulectomy were included in this prospective trial. The ends of the IAN were analyzed using quick section analysis and the results compared with those of the definite pathological report...

A palatal augmentation prosthesis (PAP) is used to facilitate improvement in the speech and swallowing functions of patients with tongue resection or tongue movement disorders. However, a PAP's effect is limited in cases where articulation disorder is severe due to wide glossectomy and/or segmental mandibulectomy. In this paper, we describe speech outcomes of a patient with an articulation disorder following glossectomy and segmental mandibulectomy. We used a palatal plate (PP) based on a PAP, along with an artificial tongue (KAT)...

Cementoblastoma is a form of benign odontogenic tumor, with the preferred treatment consisting of tooth extraction and follow-up examinations, while in certain cases, follow-up examinations without surgery are performed. Osteosarcoma of the jaw is a rare, malignant, mesenchymal tumor, associated with a high mortality rate and low incidence of metastasis. Cementoblastoma and osteosarcoma of the jaw are dissimilar in terms of their histological type and prognosis; however, there are a number of covert associations between them...

Mandibular metastatic carcinoma is a rare lesion that accounts for <1% of all oral malignancies. To provide greater experience in this field, the present study was conducted in which 6 cases of mandibular metastatic carcinoma were retrospectively reviewed. The origin of the lesions was the prostate in 2 cases, the lungs in 2 cases, the breast in 1 case and the thyroid gland in 1 case. The clinical and computed tomography features, surgical management and follow-up outcomes were investigated. The study indicated that surgeons should include the suspicion of metastasis in the differential diagnosis for mandibular tumor, particularly in patients who have a history of malignancy...

Mandibular discontinuity defects following a segmental mandibulectomy defects present a major challenge to the rehabilitation team. With no immediate intervention to rehabilitate the patient, definitive mandibular guidance prostheses with a metal guiding flange and acrylic teeth on the resected side can be used successfully to stabilize the occlusion and correct the deviation. The present case report describes the prosthodontic rehabilitation of a patient with a segmental mandibulectomy using a mandibular prosthesis with a metal guide flange and a maxillary stabilizing metal framework...

IMPORTANCE: Functional status and physiologic deficits independent of age are being recognized for surgical risk stratification. Frailty is expressed as a combination of decreased physiologic reserve and multisystem impairments distinct from normal aging processes. OBJECTIVE: To assess the predictive value of the Modified Frailty Index (mFI) for Clavien-Dindo grade IV (CDIV) (intensive care unit-level complications) and grade V (mortality) after major head and neck oncologic surgery...

Vascularized free flaps have become the gold standard in reconstructing large segmental mandibular defects; however, even when bony union and soft-tissue coverage is achieved, insufficient bone stock and altered facial contour can create functional and cosmetic problems for the patient. There have been limited case reports on the use of secondary distraction osteogenesis to address these issues. The authors report a case of bilateral mandibular distraction of deep circumflex iliac artery free flaps, used for mandibular reconstruction after total mandibulectomy for treatment of osteosarcoma...
