Languages of publication
Introduction: Sarcomas are a rare group of malignant tumours. This study highlights important findings in 91 cases of nonodontogenic sarcomas of the orofacial region. Materials and Methods: Patients who presented with orofacial sarcoma at the Oral and Maxillofacial Surgery Department of a regional University Teaching Hospital between January 1997 and June 2017 were retrospectively studied. Excluded were cases of Kaposi and odontogenic sarcomas. Data obtained were analyzed using Statistical Package for Social Sciences (SPSS) version 16 (SPSS Inc., Chicago, IL, USA). Results from descriptive statistics were represented in the form of charts. Results: A total of 91 cases were reviewed and consisted of 51 (56.0%) males and 40 (44.0%) females, with a male to female ratio of 1.3:1. The mandible (n = 47; 51.6%) and the maxilla (n = 26; 28.6%) were the major sites involved. Osteogenic sarcoma (n = 44; 48.4%) and rhabdomyosarcoma (n = 16; 17.6%) occurred more frequently. A total of 41 (45.1%) patients had surgery and the common hard tissue procedures were mandibulectomy (n = 26; 28.6%) and maxillectomy (n = 10; 11.0%). Discussion: Most recurrences were noted less than one year post treatment. There is a tendency for patients to present late and compliance with follow-up review is poor in this environment.
