Evaluation of the Morphology of the Sella Turcica in Unilateral and Bilateral Maxillary Transverse Deficiency

Abstract

Objective: The aim of this study is to evaluate the dimensions and bridging of the sella turcica in individuals with unilateral and bilateral maxillary transverse deficiency during the prepubertal and pubertal growth periods. Materials and Methods: In this retrospective study, 68 patients (28 female, 40 male) who applied for treatment at the orthodontic clinic between 2018 and 2024 and met the specified criteria were included. Patients diagnosed with maxillary transverse deficiency were grouped according to whether this anomaly was unilateral or bilateral, and further subdivided according to their skeletal maturation stages. The size and bridging of the sella turcica were measured on lateral cephalometric radiographs using Image J software. Results: No statistically significant difference was found in the measurements of calcification, length, width, and height between genders (p>0.05). Additionally, no statistically significant difference was detected in these parameters between the unilateral and bilateral crossbite groups (p>0.05). The width and height measurements of patients in the peak period were found to be significantly higher compared to those in the pre-peak period (p<0.001; p<0.001). Conclusion: It was concluded that the complex interaction between the dimensions and bridging of the sella turcica and maxillary transverse deficiency cannot be fully explained by morphological measurements alone, and that molecular-level interactions and genetic predispositions should be considered.

Tek ve Çift Taraflı Maksiller Transversal Yetersizliğe Sahip Hastalarda Sella Tursikanın Morfolojisinin Değerlendirilmesi

Abstract

Amaç: Bu çalışmanın amacı, prepubertal ve pubertal büyüme dönemindeki tek taraflı ve çift taraflı maksiller transversal yetersizlik olan bireylerde sella tursika boyutlarının ve köprülenmesinin değerlendirilmesidir. Gereç ve Yöntemler: Bu retrospektif çalışmaya 2018-2024 yılları arasında ortodonti kliniğine tedavi için başvuran ve belirlenen kriterlere sahip 68 hasta (28 kadın, 40 erkek) çalışmaya dahil edilmiştir. Maksiller transversal yetersizlik teşhisi konulmuş hastalar, bu anomalinin tek veya çift taraflı olmasına göre gruplandırılmış ve iskeletsel maturasyon evrelerine göre alt gruplara ayrılmıştır. Lateral sefalometrik röntgenlerde sella tursika boyutları ve köprülenmesi Image J yazılımı kullanılarak ölçülmüştür. Bulgular: Cinsiyetler arasında kalsifikasyon, uzunluk, genişlik ve yükseklik ölçümlerinde istatistiksel olarak anlamlı bir fark bulunamamıştır (p>0.05). Tek ve çift taraflı çapraz kapanış grupları arasında da bu parametreler açısından istatiksel olarak anlamlı bir fark tespit edilememiştir (p>0.05). Peak dönemindeki hastaların genişlik ve yükseklik ölçümleri pre-peak dönemindekilere göre istatiksel olarak anlamlı derecede daha yüksek bulunmuştur (p<0,001; p<0,001). Sonuç: Sella tursika boyutları ve köprülenmesinin transversal maksiller yetersizlikle olan karmaşık etkileşiminin sadece morfolojik ölçümlerle tam olarak açıklanamayacağı, moleküler düzeydeki etkileşimlerin ve genetik predispozisyonların dikkate alınması gerektiği düşünülmektedir.
