RESUMO
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.

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. Unfortunately, she suffered from multiple episodes of peri-implantitis and later on went on to develop oral squamous cell carcinoma around two of the dental implants. Here, we highlight the importance of regular follow-up and maintaining a high index of suspicion in high-risk patients.

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. This retrospective study used patients' medical records, radiographs, and clinical examination to assess the outcome of the surgery. Patients were followed up for an average of 3 years. RESULTS: Bone grafting was successful in all cases. No premaxillae were lost and there was no long-term morbidity of the donor site. Radiographic assessment of the bone heights showed an average of 94% retention, 3 months postoperatively. Preliminary assessment of maxillary canine eruption is encouraging, with 79% being fully erupted in those patients who are at least 3 years post-bone grafting. CONCLUSION: Premaxillary osteotomy allows repositioning of the premaxilla to its optimal preplanned position and successful closure of all fistulae. We have found that use of a collagen membrane is a useful adjunct.
