Mandibular Odontoma: Excision from a Combined Intraoral and Transcervical Approach

Author and Disclosure Information


ODONTOMAS are benign tumors of the jaws, which are derived from dental elements.1, 2 They occur twice as often in females as in males, and they are most frequently discovered in the second and third decades of life. These hard, radiopaque tumors usually cause no symptoms, diagnosis being incidental to routine roentogenographic examination of the jaws. The most common site is in the area of the second and third molars, where they may prevent eruption of contiguous teeth.3 Occasionally odontomas cause bulging and pain in the jaw.

These tumors, rarely bulky or large, most frequently are removed by means of the intraoral approach, thus easily preserving the continuity of the mandible. The patient reported here had an odontoma so large that, at first, resection of the involved mandible seemed to be the only means to eradicate the tumor. The patient was referred to us in the hopes of avoiding partial mandibulectomy. The tumor was removed with relative ease by using a combined intraoral and transcervical approach, and the continuity of the mandible was preserved.

Report of a Case

A 16-year-old white girl was admitted to the Cleveland Clinic Hospital on March 30, 1964, because of swelling and pain in the right jaw. There had been gradual swelling of the jaw for more than one year, with some pain and tenderness over the area for several months. Her medical history was noncontributory.

Examination revealed facial asymmetry, the right mandible being larger than the left. Intraoral examination of the mandible disclosed both. . .
