Purpose: To evaluate the canalicular trauma causes and the characteristics of the patients in our region. Local: Faculdade de Medicina de Botucatu - UNESP - Botucatu, São Paulo. Method: A retrospective observational study was conducted in a 7 years period evaluating 25 canalicular trauma carriers according gender, occupation, cause and lesion localization, associated structures affected, time to surgical procedure, surgery performed and results with the treatment. Results and conclusion: 68,0% of the patients were male and there is no age prevalence. The car accidents was the most important cause of canalicular trauma.

Extrusão dos implantes em portadores de cavidade anoftálmica

Purpose: To evaluate the characteristics of patients with anophthalmic cavity who developed sphere extrusion. Methods: A retrospective observational study was done evaluating 37 patients with anophthalmic cavity and sphere extrusion at the Faculdade de Medicina de Botucatu-UNESP. Results: Extrusion was observed in enucleated and eviscerated cavities. The majority of the patients had the eye removed because of phthisis bulbi or trauma and the extrusion happened 1 or 2 years after the surgery. Extrusion was preceded by conjunctival dehiscence and exposure of the sphere and occurred with all used implants. Conclusion: Complications after orbital implant placement are a possibility. Dehiscence and sphere extrusion may happen and another surgery would be necessary. The patient and the ophthalmologist have to be prepared for this.

Orbitoethmoidal impacted injury by kitchen knife causing abducens nerve palsy

Introduction: Impacted knife injuries in the maxillofacial region are rare and infrequently reported. In cases of injury involving orbit or eye, these reports are even rarer. Discussion: Damage to the orbital contents may result in a rupture of the globe, extraocular muscle injury, lacrimal gland damage, and others. Orbital foreign bodies are not only difficult to detect, and clinical features vary according to its size, characteristics, shape, penetrating method, and site. In this report, a case of abducens nerve palsy after orbitoethmoidal knife injury is presented. © 2010 Springer-Verlag.
