A case of acromegaly - Evaluation of dentofacial abnormalities.

The authors report the case of a 39-year-old woman with acromegaly due to putuitary adenoma, who had been treated at our hospital's Department of Neurosurgery. The patient was referred to our clinic for evaluation of dentofacial abnormalities. She was 167cm tall and weighed 72kg, the soft tissue of the extremities was thick and the skin was rough surfaced. Extraoral examination revealed remarkable mandibular prognathism and protrusion of the superciliary arch specific to this disease. Intraorally, there was macroglossia and no occlusion was seen except for the right molar region. Over-jet was-3mm. Cephalometric analysis revealed the following findings: decrease of SNA due to the protrusion of the point N, almost normal mandibular plane angle due to overclosure, and a relatively small gonial angle in comparison with other types of skeletal mandibular prognathism. As the abnormalities were beyond surgical correction, occlusion was corrected prosthetically by an over-lay full denture of the maxilla and a partial denture of the mandible.
