OBJECTIVES: The craniofacial surgery is therapy of choice for tumors lesions which compromise the upper structure bones, orbital fosse and anterior cranial fosse. The multicyst ameloblastoma is a benign odontogenic tumor, locally aggressive, and accounts for 1 % of all maxilla tumors. The high rate of local recurrence and extension beyond radiological limits requires in bloc surgery, with a major esthetic impact for the patient. METHODS: A case report descriptive study and literature review, of patient to viewer in the Service of Surgery I of Hospital Vargas of Caracas. RESULTS: Female patient of 43 years old with diagnoses of multirecurrent multicyst ameloblastoma who undergo to craniofacial surgery with oncological margins, and she was reconstructed with a micro free flap of rectum abdominal. CONCLUSION: The craniofacial surgery is the therapy of choice for tumors located upper Ohngren´s line. One adequate resection must include anterior cranial fosse floor and orbital medial and upper walls and the orbital content. Orbital exenteration is sometimes necessary. In the mayority of cases the eye was sacrificed. The multicyst ameloblastoma is a benign odontogenic tumor, locally aggressive; 15 % 20 % are maxilla located, with a poor prognoses, because higher rates of post surgery recurrence, local and invasion to health tissues and extension, and high malignant transformation. In bloc resection is required, with a major esthetic impact for the patients. The reconstruction with a micro surgery rectums abdominals free flap is a versatile choice for these patients
