ABSTRACT
Extraoral implants are used increasingly frequently in the wake of ablative tumor surgery and adjuvant radiation or chemotherapy for craniofacial rehabilitation with facial prostheses and epitheses. However, high rates of nonintegration and implant loss have been reported for extraoral implants, especially for those in the periorbital region following irradiation. This case report and corresponding histologic evaluation describe the osseointegration pattern in irradiated periorbital bone, based on the example of 3 retrieved, clinically integrated, stable titanium screw implants.

OBJECTIVE: The aim of this study was to examine the evolution of hospital stays and utilization of outpatient facilities for the treatment of five congenital malformations (choanal atresia, isolated cleft lip, isolated cleft palate, branchial cyst-sinus and thyroglossal duct cyst-sinus). METHOD: A retrospective review of MED-ECHO data for the province of Quebec from 1983 to 1995 was conducted. RESULTS: For three of the five studied malformations (cleft palate, branchial cyst-sinus, and thyroglossal duct cyst-sinus), there has been a trend toward reduced hospital stay and increased utilization of out-patient facilities. CONCLUSION: There has been a general tendency to reduce hospital stays even in procedures with potential airway and bleeding complications.

The authors present the prosthetic rehabilitation of a young patient nineteen years old, radiated at four years old, during the treatment of right nasal fossa malignant tumour. Only metallic mandibular and maxillary dentals coverage can be considered after the realization of temporary supra-dental resin removable dentures, testing the possibilities of treatment, on esthetic and functional points of view.

The radical maxillectomy performed for cancer of the paranasal sinuses has as its sequella some of the potentially most devastating functional losses in the field of head and neck oncology. The patient is left after surgical management with a defect that often prevents effective speech, deglutition, and mastication. This paper addresses the surgical considerations involved in the performance of a radical maxillectomy that can result in a favorable defect allowing subsequent optimal prosthetic rehabilitation of the patient.

This is a report of the successful reconstruction in two cases of a total cheek defect after radical maxillectomy with orbital exenteration for cancer of the maxillary sinus, in one stage, utilizing a double-folded free latissimus dorsi myocutaneous flap. The importance of preoperative angiography to identify suitable donor vessels, and of microneurovascular anastomosis to maintain the normal function of the transplanted muscle is stressed.
