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...

OBJECTIVES Odontogenic chronic rhinosinusitis (CRS) is an epidemiologically important disease process due, in part, to the increasingly commonplace use of dental restorative procedures such as zygomatic implantation. Traditional management of this clinical entity typically entails extraction of the infected hardware via an open or endoscopic approach. We describe a novel management strategy of ...

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...

Antrochoanal polyp (ACP) are benign lesions that originate from the mucosa of maxillary sinus, and extend into nasal cavity to reach choana nasopharynx. The treatment ACP is surgical, endoscopic medial maxillectomy (EMM) one options for surgical therapy. generally affects adolescents but in this case by adults. To report analyze adult patient with EMM technique. A 45-year-old man an completely ...

INTRODUCTION Restoring the normal separation that exists between the oral cavity and the nasal cavity is critical in allowing a patient to maintain speech and swallowing function after maxillectomy. Failure of adequate separation after maxillectomy will often result in severe oronasal incompetence, which is generally not possible for the patient to overcome without intervention. Two broad categ...
