The maxillary accessory ostium (AMO) has been associated with chronic rhinosinusitis and nasal septal deviation (NSD), but AMO may also be present in healthy individuals. AMO's purpose, origin, and effects are uncertain. This study aimed to investigate the types and frequency of AMO and NSD, as well as their relationship.
In our retrospective, single-center study, paranasal sinus tomographs performed in our clinic between 2022 and 2023 were scanned, and 200 patients who met the inclusion criteria were evaluated in terms of AMO direction (right/left), accessory ostium location (superior/middle/inferior 1/3), presence of NSD, and deviation type according to the Mladina index.
60.5% of the patients were female and 39.5% were male. AMO distribution was similar between the groups (p>0.05). There was no significant correlation between the presence and localization of AMO and the presence of NSD (p>0.05). NSD was detected in 93 patients (89.4%) with AMO and 78 patients (81.3%) without AMO (p=0.16). The distribution of NSD presence and types was similar in right or left localization, AMO (+) and AMO (-) patients (p>0.05).
The evidence that AMOs cause chronic sinusitis and FESS failure is insufficient and cannot explain the presence of AMOs in healthy individuals or children. There are very few studies in the literature examining the NSD-AMO relationship. In our study, high rates of NSD and AMO were found in individuals without paranasal disease, but no statistically significant relationship was found between the presence, location, and type of NSD and AMO. Early-onset, long-term prospective studies on the relationship between NSD and AMO may help to explain the etiopathogenesis of paranasal diseases that reduce quality of life.
上颌窦副口（AMO）与慢性鼻-鼻窦炎及鼻中隔偏曲（NSD）有关，但健康个体中也可能存在AMO。AMO的目的、起源及影响尚不确定。本研究旨在调查AMO和NSD的类型及发生率，以及它们之间的关系。
在我们的回顾性单中心研究中，对2022年至2023年在我们诊所进行的鼻窦断层扫描进行分析，根据Mladina指数，对符合纳入标准的200例患者的AMO方向（右/左）、副口位置（上/中/下1/3）、NSD的存在情况及偏曲类型进行评估。
60.5%的患者为女性，39.5%为男性。各组间AMO分布相似（p>0.05）。AMO的存在及定位与NSD的存在之间无显著相关性（p>0.05）。在有AMO的93例患者（89.4%）和无AMO的78例患者（81.3%）中均检测到NSD（p=0.16）。NSD的存在及类型在右侧或左侧定位、AMO（+）和AMO（-）患者中的分布相似（p>0.05）。
AMO导致慢性鼻窦炎和功能性鼻内镜鼻窦手术失败的证据不足，且无法解释健康个体或儿童中AMO的存在。文献中很少有研究探讨NSD与AMO的关系。在我们的研究中，在无鼻窦疾病的个体中发现NSD和AMO的发生率较高，但NSD的存在、位置和类型与AMO之间未发现统计学上的显著关系。关于NSD与AMO关系的早期发病、长期前瞻性研究可能有助于解释降低生活质量的鼻窦疾病的发病机制。
