We have investigated the interface between bone and chronic implants of nacre in sheep. There was no foreign body reaction over the period of 10 months and the implants were not broken down. Light microscopy indicated activity within an osteoprogenitor cellular layer lining the implant, resulting in a complete sequence of new bone formation. Nacre appeared(More)
The defective areas in the premolar-molar region of maxillary alveolar bone of eight patients were reconstructed using powdered nacre from the giant oyster Pinctada maxima. Histological, microradiographic and polarized light studies of drill biopsies taken 6 months postoperatively showed that nacre was tightly bound to newly-formed bone. The nacre was(More)
A case is reported of necrosis of the columella nasi due to prolonged intubation in a 21-year-old road traffic accident patient. He was intubated by the nasal route because of combined head and facial injuries. The necrosis was discovered during surgery for repair of the bony facial injuries. As the patient was in a poor condition, the lesion was not(More)
The use of bicoronal incisions has been sufficiently described in neurosurgery and craniofacial surgery including osteotomies and injuries. This approach provides excellent surgical access for nasal reconstruction with a very low rate of morbidity. A series of 11 patients, together with three case reports, illustrates the advantages and possible(More)

Carotid-cavernous fistulas are unusual complications of facial traumas but this life-threatening complication requires a rapid diagnosis. Noninvasive procedures as ultrasounds will confirm the diagnosis and are helpful to demonstrate hemodynamic conditions of the fistula. Angiography remains the main radiologic examination and embolization is now the(More)
