OBJECTIVE AND PATIENTS: Patients with acromegaly (12 women, 26 men) and a control group (36 women, 50 men) were chosen for cephalometry to assess the size, shape and positional characteristics of the craniofacial bones and the upper airways. RESULTS: When compared with the controls, patients of both sexes with acromegaly were found to have significant anomalies in the orofacial skeleton: increased facial height, elongated ascending ramus mandibulae and greater basion-supramentale distance, a negative difference between maxillary and mandibular protrusions, enlarged lower part of the gonion angle and of the angle of inclination of the maxilla, as well as alterations in the neurocranium: enlargement of sella turcica and of sinus frontalis and protrusion of the supraorbital ridges. As for the soft tissues, patients with acromegaly exhibited an elongated soft palate and a diminished angle between the uvular axis and the palatal plane. A comparison between the cephalometric parameters of patients with active acromegaly and those without active disease revealed no significant differences in either sex. CONCLUSION: Patients with acromegaly exhibited an enlargement of all parts of the neurocranium and orofacial bones except the maxilla. The greatest anomaly was seen in the mandible, with greater enlargement of the ascending ramus than of the body of the mandible. The shape of this bone was also altered.
