Surgical defects of mandibular complex have been repaired most successfully with autogenous composite bone grafts. However, their use believes inherent disadvantages associated with donor sites. Usage of cryosurgery techniques in the management of ameloblastoma is predictable operative procedure with relatively limited patient morbidity.
10 patients of mandibular ameloblastoma are presented, with age range from 15 to 58 yrs, treated by replacing back the resected mandibular segment, devitalized with liquid nitrogen cryosurgery. The length of follow up ranged from 6 months to 4 years.
According to the location of the tumor, it was divided into four types. The most common complication found was intra oral wound dehiscence. Sequestration of the devitalized bone and subsequent removal of the graft was also observed. Partial recovery of the sensation in the lower lip was found in 5 patients. Till date, no case of pathologic fracture and recurrence has been found in any of our patient. Majority of the patients had esthetically acceptable post surgical contour, with good movements and function of mandible.
The clinical success of this technique not only gives good esthetics and function, but is of a tremendous value to the physical and emotional well being of these patients. One should always keep in mind the vulnerability of the oral suture line to undergo dehiscence. Attention should be given to the improved soft tissue coverage on the oral aspect.
