[Unilateral hypertrophy of the coronoid process associated with facial asymmetry. Case report]

A rare case of unilateral coronoid process hypertrophy associated with limitation of mouth opening, deviation of the mandible to the affected side and facial asymmetry is reported. The importance of a thorough preoperative clinical and radiological examination is stressed. The resection of the coronoid process via an intraoral approach and the subsequent physiotherapy led to a good functional and aesthetic result.
