Fulltext PDFIntroduction: The mandible like other facial bones can be associated with pathological processes which can either be primary or secondary, usually being treated by resection of the affected portion of the mandible. There exist different mandibular defect classification; most of the available classifications are directed to mandibular defects following the surgical excision of mandibular tumors or composite defects due to various etiologies mentioned. Materials and Methods: About 47 cases of mandibulectomy done at the oral and maxillofacial surgery department University College Hospital were reviewed and different patterns and distributions were observed and these were used to generate a spread sheet which was then analyzed using SPSS version 23. The result of this review was used to propose the classification. Result: About 47 cases of mandibulectomies were reviewed and different portion of the mandible resected were recorded. The most common types of mandibulectomy was that of one side of the mandible crossing the midline to the other side, others include removal of the whole mandible, posterior mandibulectomy of one side not crossing the midline, anterior mandibulectomy crossing the midline, anterior mandibulectomy not crossing midline (one sided), one half of the mandible, part of the mandible without continuity defect. Conclusion: The proposed mandibular defect/mandibulectomy is therefore based on these findings as follows: 1) Total mandibulectomy. 2) Partial mandibulectomy. I. Segmental mandibulectomy II. Hemi-mandibulectomy (right or left) III. Subtotal mandibulectomy (right or left) IV. Unilateral free end mandibulectomy (right or left) V. Bounded unilateral segmental mandibulectomy (right or left) VI. Bounded bilateral mandibulectomy B. Marginal mandibulectomy
