Reimplantation of freeze-treated and saline-treated mandibular bone.

Mandibular bone devitalized by freezing after removal from the body and subsequently reimplanted was observed for its potential to reunite and grow in comparison to a similar saline-treated section of bone from the same animal. After a year, there were no significant discernible clinical or histological differences between the slaine-treated and the frozen bone. Approximately the same amount of histologically indistinguishable bone formed in either instance. The results suggest that a partially resected mandible subjected to freezing maintains the same capacity to act as an autogenous graft as does bone partially devitalized by immersion in saline solution.

Survey of resident-selection procedures for oral surgery graduate programs.

Results of a survey of the resident-selection procedures for oral surgery graduate programs have been reported. Data on the application process, interview mechanisms, decision process, and a retrospective view of past resident selections have been presented. Seventy-one percent of the respondents were satisfied with their current interview process. Eighty-two percent of the residents viewed retrospectively were considered worthy of reselection.

Reimplantation of freeze-treated mandibular bone.

Mandibular bone devitalized by freezing after removal from the body and subsequent reimplantation was observed for its potential to act as a framework of new bone formation. Clinical union and bony replacement occurred when the reimplanted bone was covered by healthy, well-vascularized soft tissue. New bone initially formed subperiosteally along the devitalized bone. Later specimens showed increased production of endosteal bone. The results suggest that a resected mandible subjected to freezing might be immediately reimplanted as a graft when the mandible is involved as part of a radical operative procedure. Further studies are indicated to evaluate this potential when the periosteal covering is removed.

Postoperative sequelae of cryosurgery.

Cryosurgery is a proved method for treatment of neoplasms of the soft and hard tissues of the oral cavity. It is not free, however, from postoperative complications. Delayed healing and extensive scarring are common occurrences. Significant functional and esthetic impairment, although uncommon, can result. Exposure of lingual mandibular bone can interfere with prosthetic replacement. Postfreezing evaluation of cervical nodes in patients treated for oral cancers can be complicated by persistent lymphadenopathy. Cryosurgery of irradiated bone or overlying tissue can result in osteoradionecrosis. Although the possibility of these complications should not be a major deterrent when it is felt that cryosurgery is the preferred method for treating a malignancy, the complications deserve careful consideration in the management of benign lesions.
