Unilateral chronic maxillary sinusitis is frequently attributed to dental origin. The goal of this retrospective study is to determine the frequency of maxillary sinusitis due to a foreign body of dental origin and its characteristics.
Review of 197 sinusitis cases with maxillary sinus involvement operated in our department from 1991 to 1999. Selection of the 17 cases preoperatively suspect to be due to a foreign body of dental origin.
9% of the 197 maxillary sinusitis were classified "odontogenic". Intra-sinusal foreign bodies were identified in 5%: 2% of dental origin, 1% dental or radicular remnants, 2% of "pseudo" foreign bodies of mycotic origin.
Chronic maxillary sinusitis attributable to a dental foreign body is rare and overestimated. There exists an important disproportion between the number of intra-sinusal dental foreign bodies and the number of patients who are symptomatic. Treatment is surgical by oral antrotomy and/or endonasal meatotomy. Only a prospective study could give a real estimation of the proportion of symptomatic cases and determine the predisposing factors.
单侧慢性上颌窦炎常被认为源于牙齿。本回顾性研究的目的是确定牙源性异物导致上颌窦炎的发生率及其特征。
回顾1991年至1999年在我科接受手术的197例累及上颌窦的鼻窦炎病例。选取术前怀疑由牙源性异物导致的17例病例。
197例上颌窦炎病例中，9%被归类为“牙源性”。鼻窦内异物占5%：牙源性占2%，牙齿或牙根残余占1%，霉菌性“假性”异物占2%。
由牙源性异物导致的慢性上颌窦炎罕见且被高估。鼻窦内牙源性异物数量与有症状患者数量之间存在显著差异。治疗采用经口上颌窦切开术和/或鼻内鼻肉切开术。只有前瞻性研究才能真正评估有症状病例的比例并确定诱发因素。
