摘要/Abstract

摘要： ［摘要］目的评估上颌后牙游离缺失患者上颌窦底壁骨分嵴的分布情况。方法纳入2011年1月至2013年12月在四川省人民医院就诊的上颌后牙游离缺失患者，对其CBCT资料进行统计分析，评估在上颌后牙游离缺失情况下上颌窦底壁骨分嵴的分布情况。结果符合纳入标准的患者共计253例（男132例，女121例），上颌窦共计289个。骨分嵴的检出率约为26.09%，其中上颌前磨牙区12例（18.18%），显著高于低于磨牙区54例（81.82%），骨分嵴的平均高度为（3.87±1.10）mm，不同年龄和性别差异无统计学意义。骨分嵴走向分布中颊腭向为59个（89.39%），近远中向为7个（10.61%）。结论上颌窦底壁骨分嵴发生率高，走向复杂，拟行上颌窦提升手术前对上颌窦底骨分嵴进行评估是必不可少的，CBCT不失为评估上颌窦底骨分嵴的好方法。

Abstract: Objective　To determine the prevalence, location and height of maxillary sinus septa in the patients without upper posterior teeth at one or two sides. Methods: The patients who underwent CBCT scan and without upper posterior teeth at one or two sides in Sichuan Provincial People’s Hospital between January of 2011 and December of 2013 were selected and the prevalence, location and height of the maxillary sinus septa were analyzed. Results: There were a total of 253 patients (male 132,female 121) with 289 sinus, and the prevalence of maxillary sinus segments with septa was 26.09%. The location of septa observed in all study groups demonstrated a greater prevalence (81.82%) in the molar region than in the pre-molar regions. The mean height of septa was 3.87±1.10mm, and no statistically significant differences were observed with regard to gender or age. The distribution of septa in buccal-palate(89.39%) was far more than that in mesial-distal direction(10.61%). Conclusion: Septa of various heights and courses developed in all parts of the maxillary sinus. Therefore, to prevent possible complications during sinus surgery, CBCT is a good choice to observe the septa in maxillary sinus.
