Study design: Observational Study
Abstract: to evaluate if any significant difference exists between them, which could be the basis for early diagnosis. Materials a n d MethodsThis study was done over 15-year-old patients seeking orthodontic treatment, depicting clear presentation of sella turcica on the lateral cephalogram.Patients with any major illness or syndromic patients (physically/mentally/both) were excluded from the study.A total of 60 lateral cephalograms were selected, and based on introduction Sella turcica and nasomaxillary complex are related to the fetal neural crest cells.Most commonly and easily recognized wellknown anatomical landmark on a lateral cephalogram is sella turcica, which, in turn, is used for diagnosing any pathology related to cranial base.Due to its position, it is used as an additional diagnostic information associated with hypophysis or various affected syndromes associated with cranial base. 1 A saddle shape depression of sella turcica enclosing pituitary gland is often used as cephalometric key point for evaluation of jaw position as well as their relation to cranial base. 2 Normally, in lateral cephalogram, the shape of sella turcica is U-shaped.Any deviation from the normal may indicate a pathological condition.Large size of pituitary gland may indicate tumor with overproduction of hormones such as adrenocorticotropic hormone (ACTH), thyroidstimulating hormone (TSH), prolactin, and vasopressin leading to acromegaly or amenorrhea.On the other hand, reduced size may cause decrease in size of pituitary function leading to retarded bone maturation and reduced growth.3 Noticing any pathologic condition on a lateral cephalogram is a reminder of the important role that the dentist may play in identifying craniofacial lesions.Therefore, dentist must be acquainted with the common anatomical structures as well as the morphologic diversity in order to recognize any pathological changes indicating a medical condition, even before they become clinically evident.3,4 Although many features related to cephalometric radiography have been investigated and discussed but dimension of sella turcica has received little attention.Hence, this study aims to assess and determine the size of the sella turcica in skeletal malocclusion and 1,
