Abstract：
UNASSIGNED: Eustachian tube dysfunction (ETD) is considered a causative factor for middle ear disease as well as treatment failure. The pathogenesis may be a result of chronic infection, allergy, laryngopharyngeal reflux, primary mucosal disease, dysfunction of the dilation mechanism and anatomical obstruction. Hence, it becomes essential to know the structure and anatomical variations of the Eustachian tube(ET), particularly with the advent of novel therapeutic options such as tuboplasty to ensure optimal therapeutic outcome.
UNASSIGNED: This cross-sectional study is done to perform multiparametric measurements of the ET and peritubal region using computed tomography and develop a structured protocol for pre-tuboplasty workup.
UNASSIGNED: This study was done for a period of 20 months, in 100 normal subjects aged between 18 and 60 years, who underwent computed tomography (CT) study of the head and face region, for indications other than nasal/ pharyngeal and sinus disease.
UNASSIGNED: The mean bony, cartilaginous and overall ET lengths were higher in males. In females, the mean ET angles with Reid\'s plane were higher. Higher mean craniocaudal diameters of the ET lumen were observed in males. Carotid canal dehiscence was seen in equal prevalence on both sides (5%), with no significant gender differences.
UNASSIGNED: Therapeutic interventions such as eustachian tuboplasty will benefit from preoperative imaging based planning. This structured protocol provides standardization of pre-operative workup for tuboplasty.

摘要：
■咽鼓管功能障碍（ETD）被认为是中耳疾病以及治疗失败的原因。发病机制可能是慢性感染的结果，过敏,咽喉反流,原发性粘膜疾病，扩张机制和解剖学障碍的功能障碍。因此，了解咽鼓管（ET）的结构和解剖变化变得至关重要，特别是随着新的治疗选择，如输卵管成形术的出现，以确保最佳的治疗效果。
■这项横断面研究是为了使用计算机断层扫描对ET和输卵管周围区域进行多参数测量，并制定了用于输卵管成形术前检查的结构化方案。
■这项研究为期20个月，在100名年龄在18至60岁之间的正常受试者中，他们接受了头部和面部区域的计算机断层扫描（CT）研究，除鼻/咽部和鼻窦疾病以外的适应症。
■平均骨骼，男性的软骨和总体ET长度较高。在女性中，与里德平面的平均ET角较高。在男性中观察到较高的ET腔平均颅尾直径。颈动脉管开裂在两侧的患病率相同（5％），没有明显的性别差异。
■咽鼓管成形术等治疗干预措施将受益于基于术前影像学的计划。这种结构化的协议提供了用于输卵管成形术的术前检查的标准化。
