Loss of the caudal maxilla and ventral orbit after tumor resections can have negative functional and esthetic influences on the eye involved. This article reports on a case of a caudal maxillary acanthomatous ameloblastoma involving the ventral orbit that was resected and stabilized with a masseter muscle flap. The masseter muscle flap was generated from the superficial belly of the masseter mu...

in wistar rats, reproductive behavior is controlled in a neural circuit of ventral forebrain including the medial amygdala (me), bed nucleus of the stria terminalis (bnst) and medial preoptic area (mpoa) via perception of social odors. diabetes mellitus (dm) is a widespread metabolic disease that affects many organs in a variety of levels. dm can cause central neuropathies such as neuronal apop...

Patients may face functional, aesthetic, and social distress because of the palatal defects. Prosthetic rehabilitation of maxillectomy or developmental defect can be challenging for prosthodontists. Prognosis of the prosthetic appliances can be affected not only by patients' own ability to adapt to the prosthesis but also by the factors like the remaining teeth, bony structure, and existing muc...

OBJECTIVES/HYPOTHESIS To determine the long-term outcomes of a prospective cohort of 20 patients who had nasopharyngectomy using an open partial-maxillectomy approach. METHOD A prospective cohort study of the surgical outcomes of patients with recurrent T1 (rT1) and rT2 nasopharyngeal carcinoma recurrence. RESULTS There were 14 male and six female patients. The mean age was 49 years. The me...

Maxillary obturator prosthesis is the most frequent treatment option for management of partial or total maxillectomy. Heavy weight of the obturators is often a dislocating factor. Hollowing the prosthesis to reduce its weight is the well established fact. The alternate technique to hollow-out the prosthesis has been described in this article which is a variation of previously described processi...

Osteosarcoma is a bone tumor that consists of malignant cells that produce immature bone. Is a bone tumor that develops during periods of rapid growth in adolescents and young adults. It is the most common type of bone cancer in children and adolescents. The diagnosis and treatment of patients with osteosarcoma requires a multidisciplinary team approach. Resection of maxillary tumours remains a...

This study reviews our experience with free microvascular tissue transfer for the repair of midfacial defects in surgical oncology. From 2000 to 2008, eight patients with maxillectomy defects were immediately reconstructed using free flaps. Their clinical charts were retrospectively reviewed to record demographic data, ablative and reconstructive procedures, complications and outcome. Free tiss...

To reveal the acoustic characteristics associated with hypernasality and to ascertain their correlation to the severity of hypernasality, 30 speech samples produced by 15 maxillectomy patients were acoustically analysed with and without an obturator prosthesis in place. The isolated, sustained Japanese vowel /i/ was used as the stimulus for acoustic measurement and perceptual judgment to evalua...
