We investigated the relationship between sella turcica size and maxillofacial morphology in skeletal Class III malocclusion among Japanese adults.The subjects were 115 patients visiting the Osaka Dental University Hospital between May 2014 and March 2019 with ∠ANB<1.0°, negative overjet, and an absence of congenital abnormalities in the skeletal Class III malocclusion group. Individuals with 1.0° ≤ ∠ANB ≤ 4.0° were included as controls (n=122). Lateral cephalometric analysis was performed to measure the overbite depth indicator (ODI), the maximum anteroposterior width (W) of the sella turcica, depth (De) of the sella turcica, and diameter (Di) of the sella turcica; and interclinoid distance (I), among other parameters.
In the skeletal Class III malocclusion group, Di and I were significantly smaller among the males, and De was significantly larger among females. In males, a positive correlation was observed between De and ODI. In females, a positive correlation was observed between W and Pog to NB, De and ∠ANB, ∠Occlusal pl to SN, and ∠GoGn to SN. These findings indicate the possibility of predicting maxillofacial growth based on sella turcica morphology, which could help improve orthodontic treatment. (J Osaka Dent Univ 2023; 57: 99-106)
