Sella turcica dimensions and maxillary growth in patients with unilateral cleft lip and palate

J Stomatol Oral Maxillofac Surg. 2022 Nov;123(6):e916-e921. doi: 10.1016/j.jormas.2022.06.008. Epub 2022 Jun 10.


Objectives: We aimed to investigate associations between sella turcica dimensions and maxillary growth in children with unilateral cleft lip and palate (UCLP).

Methods: Forty-nine patients with non-syndromic UCLP, prior to secondary alveolar bone-grafting, were included. The outcomes measured were sella turcica and maxillary cephalometric measurements, and scores representing dental arch relationships derived from dental casts. On lateral cephalograms, sella width, height, and area were measured, as well as maxillary length, height, protrusion, and inclination. Dental arch relationships were measured using the modified Huddart/Bodenham (MHB) scoring system, and translated GOSLON yardstick score. Multiple linear regression was used to assess associations between sella turcica measurements and either cephalometric parameters or MHB/GOSLON scores, including age and sex as covariables.

Results: No significant associations were found between sella turcica dimensions and dental arch relationships. For cephalometric measurements, sella height and area were associated with basal maxillary length, alveolar maxillary length, and anterior maxillary height.

Conclusions: Sella height and area seem to be predictors for both maxillary length and height as assessed cephalometrically, in a sample of patients with non-syndromic UCLP.
