Dentigerous Cyst and Ameloblastoma of the Jaws.

Aim: To determine how many ameloblastomas were misdiagnosed as dentigerous cysts (DCs) by correlating the radiological and histopathological features of a series of both entities.

Methods And Results: Histopathology reports and radiological imaging of 135 DCs and 43 ameloblastomas were reviewed. Any clinical or radiological feature that suggested that the diagnosis of DC was wrong-for example, absence of an unerupted tooth-prompted review of the original histology.

Biodegradable fixation in oral and maxillofacial surgery.

Unlabelled: Fixation of the maxillofacial skeleton following trauma or osteotomy surgery has been achieved by the use of titanium plates and screws for the past two decades. Advances in materials science has enabled the development of biodegradable or resorbable plates and screws for internal fixation of the maxillofacial skeleton. This paper presents the biochemistry of resorbable materials and our early experiences in their clinical applications.

Surgical management of the severely contracted socket following reconstruction.

Purpose: To present a surgical technique for the early maintenance of the severely contracted socket following reconstruction.

Methods: Two patients with severely contracted sockets following multiple procedures and recurrent failure were identified over a 1 year period. Following fornix and eyelid reconstruction, silicone fixative was injected into the fornix through a standard conformer.

A rare case of an extensive plunging ranula: discussion of imaging, diagnosis, and management.

A plunging ranula is a mucous extravasation cyst appearing as a swelling in the submental and submandibular regions. We describe a rare case of massive plunging ranula involving multiple tissue spaces. A magnetic resonance imaging scan revealed the true extent of the lesion and its relationship to the surrounding structures.
