Penetrating knife injury to the frontal lobe--a case report.

Penetrating injuries of the craniofacial region are increasing and have the potential to cause severe vascular and neurological deficit. We present our management of a case with a knife stab injury to the infra-orbital region, traversing the orbit and penetrating into the anterior cranial fossa, the tip lying in close proximity to the anterior cerebral circulation.

Squamous cell carcinoma presenting as peri-implantitis: a case report.

Dental implants have proved to be a useful adjunct in the rehabilitation of oral cancer patients. We describe the case of a 62-year-old woman who presented with a white patch in the oral cavity, diagnosed to be a squamous cell carcinoma. She underwent extensive surgery including microvascular reconstruction, followed by implant rehabilitation.

Premaxillary osteotomy and guided tissue regeneration in secondary bone grafting in children with bilateral cleft lip and palate.

Objective: To introduce a surgical technique for secondary alveolar bone grafting performed in conjunction with premaxillary osteotomy and guided tissue regeneration in children with bilateral clefts. This paper also looks at the outcomes of this surgery in a series of 15 consecutive patients.

Methods: Secondary alveolar bone grafting (with a premaxillary osteotomy and guided tissue regeneration with a collagen membrane) is usually carried out in the mixed dentition stage.
