Traumatic Optic Neuropathy and Monocular Blindness following Transnasal Penetrating Optic Canal Injury by a Wooden Foreign Body.

Purpose: To report a case of right eye blindness due to a penetrating injury in the contralateral nostril.

Methods: This is a case report of a 67-year-old patient who presented to the emergency room complaining of transient blurred vision in his right eye after falling on a small branch with no apparent injury besides minor lacerations. The following day, the patient experienced blindness in the right eye.

Horizontal alveolar ridge distraction in an edentulous patient.

Purpose: Full fixed dental rehabilitation, including attachment based over denture (to dental implants) is the optimal solution for edentulous patients, although the insertion of implants will be impossible when the alveolar ridge has been horizontally and severely absorbed. A full arch narrow ("knife-edge") alveolar crest creates a "borderline" condition. Dental implants cannot be inserted into a narrow ridge, which is also at risk of rapid absorption, especially under the pressure of a full denture.
