Facial scarring is avoided when a transoral degloving approach is used for treatment of parasymphyseal fractures. Complete visualization of the fracture line before and after the reduction is an added advantage of this safe, rapid, and technically easy approach. In patients with both parasymphyseal and condylar fractures, Risdon wires can also be used.

All oral surgeions have encountered problems associated with edema, trismus, and pain after intraoral procedures. In third-molar surgery, pain and trismus are often directly proportional to edema. Therefore, in the patient with minimal edema, pain and trismus should be proportionally reduced. Parenteral use of the corticosteroid dexamethasone, given as a transoral injection at the time of operation, appears to be effective in the prevention of postoperative edema.
During a screening examination for orthodontic evaluation and for possible partial anodontia, a large radiopaque mass was found in the right maxillary sinus of a 12-year-old boy. Further radiographic views were used to locate and establish a working diagnosis. The mass was removed with use of a standard Caldwell-Luc approach. It was diagnosed histologically as a complex odontoma.
Denture cleansers are ubiquitous compounds frequently found in the household. Severe oral cavity burns were clinically observed in a two-year-old female who accidentally ingested a denture cleanser powder, Denalan. Experimental studies were carried out to investigate the caustic, chemical and histopathological properties of this compound. Denalan was found to be a powerful alkali agent which caused severe upper digestive tract burns.
