Hydroxylapatite and fibrin glue mixture in a subperiosteal tunnel for ridge augmentation

The present investigation was undertaken to evaluate combining the use of a human fibrin sealant and hydroxylapatite particles to augment a tissue expanded lower edentulous atrophic ridges. The procedure was carried out on seven subjects not amenable for rational dentures. Results proved that the technique could efficiently overcome the problem of granules migration. It is simple, easy and leading to predictable well moulded augmented ridges with minimal resorption

Clinical and electrodiagnostic assessment of facial nerve affection following TMJ surgery

The preauricular and endaural incisions for temporomandibular joint surgery were compared in 17 patients [25 joints] regarding possible facial nerve affection. The latter was assessed clinically and through electromyographic testing. Only one case out of 8 performed through the endaural approach showed temporary lid incompetence that regained normality after one week, while 6 cases out of the 17 preauricular incisions resulted in temporal and/or zygomatic branch affection. Using electromyography, figures of residual motor function were about normal again within 16 weeks
