蝶鞍的类型和鞍桥的发生率

蝶鞍位于颅窝中部,蝶骨体内表面,中部是垂体窝。蝶鞍是脑颅和颅面复合体的X线分析的重要结构,在正畸中,蝶鞍中心点是头影测量片上最常使用的标志点之一,被用来测量上下颌相对于颅骨的位置,以及上下颌之间的相对位置,研究这些结构有助于正畸医生诊断,并且可以通过纵向的结构叠加来研究个体的生长,也用来评估正畸治疗结果。临床医生应熟悉该领域的正常解剖影像学和形态学的变化,以便识别和研究可能反映的病理情况。该文就蝶鞍的类型和鞍桥发生率作一综述。

Different morphological types of sella turcica and incidence rate of sella turcica bridge

Sella turcica is located in the middle cranial fossa, on the surface of sphenoid body, and its center is the pituitary fossa. Sella turcica is an important structure in the neurocranial and craniofacial complex, which is often used in radiographic analysis. In or?thodontics, sella point which is located at the center of sella turcica, is regarded as one of the most commonly used landmarks in cepha?lometrics. These landmarks, located within the craniofacial region, are used to measure the positions of maxilla and mandible in relation to the cranium. Orthodontists can benefit from studying these structures in diagnosis, studying growth in individuals through superimpo?sition of structures on a longitudinal basis, and evaluating orthodontic treatment results. Sella area is an important region, and may have variation between individuals. Therefore, understanding normal iconography and morphology of sella turcica will help orthodontists rec?ognize the pathological problems in sella turcica. This article reviewed the types of sella turcica and incidence rate of sella turcica bridge.
