Osteochondroma of mandibular condyle (OMC) is the most common benign lesion of the temporomandibular joint that causes growth of the mandibular condyle, ramus elongation and secondary facial dismorfosis. The diagnosis must be objectified clinical and histopathology, remove the tumor, reevaluate its sequel and plan surgical management due to their diagnosis. We present 2 cases, women, 29 and 50 which debuted consulting for moderate pain in the temporomandibular joint affected. Both have facial asymmetry lateromentonismo, elongation of ramus posterior contralateral overbite and canting of the occlusal plane, with 2 and 3 years of evolution estimated without lymphadenopathy and without collateral diseases. After completing the clinical trial imaging (CT, scintigraphy) and laboratory tests proceed with surgical management deferred to objectify histologic diagnosis (condylectomy mandibular and meniscopexia). After the re-evaluation of the patient and the sequel to the first surgical (condylar stump status, tumor control without recurrence, evaluation healthy condyle, and the new mandibular position) sets the new diagnostics and new therapeutic arises: occlusal stabilization (with prosthetics or orthodontics) with or without orthognathic surgery (to return the skeletal balances subsequent airway expand and improve the aesthetics). In our cases after condylectomy, a patient underwent prosthetic occlusal stabilization and other orthognathic surgery was necessary. After a year of monitoring both patients are in excellent condition. The objective diagnosis is the basis of our surgical management, obtaining diagnostic accuracy (inability quick biopsy) and a more conservative replanning after condylectomy.
