Summary
Few epidemiological studies in maxillofacial surgery describe in detail the characteristics of patients and types of intervention undertaken. The aim of this study was to determine the epidemiology of maxillofacial surgical procedures performed under general anesthesia at the Clinical Hospital San José. A retrospective study, which included 599 patients, was carried out between 2007 and 2013, according to information obtained on age, patient sex and type of intervention. Of the total procedures performed, 335 (56%) were maxillofacial trauma and 264 (44%) were non-traumatic surgeries. Average age was 38 years old. Ratio between male and female was 2.05:1. The most prevalent was mandibular fracture with 49.8%, subsequently orbito zigomatic fractures with 28.3%, panfacial with 13.7%, orbital bones 2.98%, Le Fort 2.7%, and zygomatic bone 2.1% and naso orbitoetmoidal with 0.43%. In both non traumatic surgeries the following was reported, infections 12.1%, tumors, 12%, craniofacial dysmorphosis 11.8%, multiple extractions in patients with neurological disorders 2.3%, aesthetic reconstructions 2.1%, temporomandibular joint disorders 1.6%, various oral lesions 1.1%, dysplasias 0.3% and osteosynthesis withdrawal 0.3%. Most frequent procedures performed were reduction and osteosynthesis fixation of facial fractures. Knowledge of these data provides information as to which areas to focus the department's budget on, areas in which greater specialization is required, and reinforcing the need for requirement of additional hours in the operating room.
