An enlarged sella turcica on cephalometric radiograph

A 28-year-old male presented to the Orthodontic clinic for correction of his anterior crossbite due to mandibular prognathism as a result of pituitary adenoma with acromegaly. A radiographic cephalometric analysis and clinical orthodontic examination were made. This article describes in detail the m...

Description
Summary:A 28-year-old male presented to the Orthodontic clinic for correction of his anterior crossbite due to mandibular prognathism as a result of pituitary adenoma with acromegaly. A radiographic cephalometric analysis and clinical orthodontic examination were made. This article describes in detail the methods of correcting the magnification of cephalometric linear measurements in sellar dimensions (length, depth and width) from lateral and posteroanterior cephalograms. Cephalometric findings revealed that the sella enlarged in all its dimensions with a deepening of the floor in this acromegalic case. We discuss the radiographic diagnosis of an enlarged sella turcica in intrasellar tumours and also emphasise the dentist's important role in the initial diagnosis of pituitary adenoma cases.
