Introduction: Reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. In large defects, there will be demand for regional pedicle flaps or free flaps. Hard palate separates nasal and oral cavities. Due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions ...

A simple model of the m-cornered hat estimation problem is set up and solved by the method of maximum likelihood. The method is compared by simulation to a leastsquares method of Barnes and is shown to be inferior to it on the basis of mean square error. A bootstrap method of computing estimator performance is presented.

This paper addresses the finite size 1-center placement problem on a rectangular plane in the presence of barriers. Barriers are regions in which both facility location and travel through are prohibited. The feasible region for facility placement is subdivided into cells along the lines of Larson and Sadiq (1983). To overcome complications induced by the center (minimax) objective, we analyze t...

BACKGROUND Lesions in perineal area are common. The usual treatment is coverage by skin graft and flaps which may be local, pedicled or free types. In this paper V-Y flaps were used to cover the defects. METHODS V-Y flaps were used in the gluteal area in 15 patients. Lesions were due to different causes. RESULTS Of 15 patients, 11 were males and 4 were females. Their ages ranged from 3...

background it has been reported that systemic administration of allopurinol improves cell survival. this study was aimed to evaluate effects of allopurinol on skin flaps in dogs. methods twenty dogs underwent one skin flap surgery with a 2-week interval. the first procedure was performed according to the standard protocols. the second phase was started by a 1-week pretreatment with allopurinol....

background vermilion irregularities are common secondary deformities after cleft lip repair, regressed or resected hemangiomas, trauma and tumor surgeries. vermilion deficiency attracts considerable attention and detracts from an otherwise excellent lip repair. minor and moderate vermilion defects can be corrected with upper lip advancement, rotation flaps, tongue flaps or grafts. major defects...

conclusions scarring of the neck produces problems with function, and appearance. in our view, the supraclavicular flap, a thin flap of good texture, is an excellent and highly reliable flap for covering defects of the anterior neck. this flap is easy to harvest, with good functional and aesthetic results. results thirty-seven of the 41 flaps survived completely, but there were three cases of d...

BACKGROUND This study presents an alternative in reconstruction, using free skin flaps in combination with pedicled mandible bone flaps for complex lateral mandibular defects. METHODS In all, 13 patients were included in this prospective study. Pedicled mandible myo-osseous flaps were used for reconstruction of bone defects of the lateral mandible in combination with free skin flaps, includin...
