RESUMEN
A 72-year-old woman with a history of removal of a right hemimandibular keratocyst 10 years ago was referred to our attention for a large swelling of the right cheek. The orthopantomography and the CT scan showed a huge osteolytic area of the right mandibular ramus and angle. The patient's refusal to resection and reconstruction with a free flap pushed us towards a conservative treatment. The high probability of a iatrogenic mandibular fracture during and after surgery required the design of a customised titanium plate to be preliminary placed through cervical incision along the posterior border of the mandible. The patient successfully underwent the surgical positioning of the customised plate and subsequent removal of the keratocyst. She was discharged fit and well 5 days after surgery. She did not experience any infections, pathological fractures or relapse in the 6-month follow-up.
