PURPOSE The aim of this paper is to explore the current theories about definition, classification, incidence and physiopathology of osteoradionecrosis (ORN) of the jaws. Moreover, it is discussed the predisposing and risk factors for the development of osteoradionecrosis based on the literature review. DISCUSSION Osteoradionecrosis is one of the most(More)
UNLABELLED Salvage laryngectomy in patients treated with organ preservation protocols is associated with high rates of postoperative complications. The use of non-irradiated tissue flaps in pharyngeal reconstruction could reduce the incidence of these complications. OBJECTIVE This study aims to evaluate the usefulness of the pectoralis major myocutaneous(More)

Pharyngocele, or lateral pharyngeal diverticulum (LPD), is rare, as only a few cases have been described. This condition is characterized by local bulging in the piriform recess or in a vallecula. The diagnosis, which is clinically difficult, is made by barium-swallow examination of the pharynx. Surgical repair is indicated when symptoms are present. We(More)
CONTEXT AND OBJECTIVE magnesium ion concentration is directly related and phosphorus ion concentration is inversely related to calcemia. The aim of this study was to evaluate the evolution of magnesium and phosphorus ion levels in patients undergoing thyroidectomy and correlate these with changes to calcium concentration.

Solitary fibrous tumours are spindle-cell neoplasms that usually occur in the pleura and peritoneum, and rarely involve the oral mucosa. We report a 30-year-old man with a large solitary fibrous tumour on the buccal mucosa that resembled a salivary gland neoplasm. The lesion was excised and has not recurred.
PURPOSE The aim of this paper is to explore the current theories about pretreatment assessment and dental management of patients receiving head and neck radiotherapy, and the therapeutic options to treat osteoradionecrosis of the jaws, based on the literature review. DISCUSSION Osteoradionecrosis is one of the most serious oral complications of head and(More)
Solitary fibrous tumor (SFT) is a rare spindle cell neoplasm that usually develops in the pleura and peritoneum. The head and neck region is involved in only 6% of the cases. Involvement of the parotid gland is a rare phenomenon, with only 24 cases reported in the literature. The aim of this study is to report an additional case of SFT affecting the parotid(More)
CONTEXT Kikuchi-Fujimoto disease (KFD) manifests in most cases as unilateral cervical lymphadenomegaly, with or without accompanying fever. The disease mainly affects young women and has a self-limited course. It is more common in oriental countries, with few reports of its occurrence in Brazil. KFD should be included in the differential diagnosis of(More)
OBJECTIVE To evaluate the incidence of pharyngocutaneous fistula after total laryngectomy and try to identify its predictors. METHODS From May 2005 to April 2010, 93 patients underwent total laryngectomy. We evaluated complications during and after surgery and compared them with the following variables: gender, nutritional status, previous tracheotomy,(More)
