摘要/Abstract

摘要： 目的通过CBCT上颌窦影像资料回顾性分析,比较研究本院口腔种植患者中上颌窦外生骨疣（MSE）的相关参数,并评估其与年龄和性别之间的关系。方法回顾了2023年7月至2025年4月533例于我院种植科治疗前行CBCT检查患者的上颌窦影像,收集了关于MSE位置、大小、形状、对称性、是否伴周围黏骨膜异常与上颌窦间隔及年龄和性别的相关数据,采用χ²检验、Fisher确切概率法、单因素方差对数据进行统计分析。结果 533例患者1 066侧上颌窦中有59例患者的74侧上颌窦内发现MSE影像,双侧MSE发生率（15例）25.4%。74侧MSE中,珍珠型40侧、扁平型26侧与不规则型8侧（54.1%、35.1%与10.8%）;位于上颌窦外侧壁38侧（51.4%）、窦底32侧（43.2%）、内侧壁4侧（5.4%）;49侧伴发黏骨膜异常影像（54.1%）、8侧伴发上颌窦间隔影像（10.8%）、12侧单个窦内含2个及以上独立MSE影像（16.2%）,MSE最长径（7.67±4.86）mm。性别或年龄与MSE的发生率和位置之间无统计学意义（P>0.05）。结论大多数MSE单发在单侧上颌窦的外侧壁与窦底,且不伴窦内骨间隔,多为较小的珍珠型,其上颌窦多伴黏骨膜异常影像。性别或年龄与MSE的发生率间无统计学意义,MSE的各分型与其大小有显著差异。

Abstract: Objective To retrospectively investigate the parameters of maxillary sinus exostoses (MSEs) in a dental implant potients using cone-beam computed tomography (CBCT) and evaluate its association with age and sex. Methods This study reviewed CBCT scans of the maxillary sinuses from 533 patients who underwent preoperative imaging for implant treatment at our hospital between July 2023 and April 2025. Data on MSE location, size, morphology, symmetry, presence of concurrent mucoperiosteal abnormalities, sinus septa, and demographic variables were collected. Statistical analyses included chi-square test, Fisher’s exact test, and one-way ANOVA. Results Among 1,066 maxillary sinuses in 533 patients, MSE was identified in 74 sinuses of 59 patients, with bilateral occurrence in 15 patients (25.4%). Morphologically, 54.1% (40/74) were pearl-shaped, 35.1% (26/74) flat-shaped, and 10.8% (8/74) irregular-shaped. MSEs were predominantly located on the lateral wall (51.4%, 38/74) and sinus floor (43.2%, 32/74), with 5.4% (4/74) on the medial wall. Concurrent mucoperiosteal abnormalities were observed in 54.1% (49/74) of sinuses, sinus septa in 8 sinuses (10.8%), and multiple independent MSEs in 16.2% (12/74) of affected sinuses. The mean MSE size was (7.67±4.86) mm. No significant differences were found in MSE prevalence or location across sex or age groups (P>0.05). Conclusion Most MSEs were solitary, unilateral, and located on the lateral wall or floor of the maxillary sinus without sinus septa. Approximately half were small, pearl-shaped lesions, and mucoperiosteal abnormalities coexisted in nearly half of the affected sinuses. No demographic correlations were observed, but significant variations existed in MSE morphology and size.
