Reconstruction of internal orbital wall fracture with iliac crest free bone graft: clinical, computed tomography, and magnetic resonance imaging follow-up study.

Background: The purpose of this study was to clinically and radiologically assess the outcome of internal orbital reconstruction with an iliac bone graft.

Methods: Twenty-four consecutive patients with unilateral orbital wall fractures were enrolled in this prospective study. A medial cortical wall from the anterior ilium was used for reconstruction.

Effectiveness of operative treatment of internal orbital wall fracture with polydioxanone implant.

Many implants, some made from teflon or silicone, have been used for internal orbital wall reconstruction. Late complications relating to use of such implants have been reported. In this prospective study a polydioxanone (PDS) implant absorbable in vivo was used for internal orbital wall reconstruction.

The anatomy of the killer whale middle ear (Orcinus orca).

The paper first reviews our present understanding of the functional morphology of the odontocete (toothed whale) ear. The tympano-periotic complex forming the ear region consists of a ventral bowl-shaped tympanic bone in direct contact with the surrounding soft tissues and the incident sound, and a dorsal periotic bone containing the inner ear. Apparently sound brings the tympanic bone, and especially its thin tympanic plate, into vibration.

Lag-screw osteosynthesis of mandibular condyle fractures: a clinical and radiological study.

Purpose: This study evaluates the clinical and radiologic results after open reduction and lag-screw osteosynthesis of fractured mandibular condyles.

Materials And Methods: Eleven adult patients underwent surgery for displaced or dislocated mandibular condyle fractures via a submandibular approach. The repositioned fragments were fixed using lag screws designed by Krenkel or Eckelt.

Blindness after maxillofacial blunt trauma. Evaluation of candidates for optic nerve decompression surgery.

Clinical and computerized tomography (CT) findings in 10 patients with post-traumatic blindness after maxillofacial blunt trauma were evaluated as potential candidates for optic nerve decompression surgery. The total number of blind eyes was 14. All patients suffered from midfacial fractures (isolated zygomatic fracture in 4 and Le Fort fracture in 6 cases) predominantly caused by road traffic accidents.
