A sheep bot fly, Oestrus ovis, is an obligate parasite that is found worldwide, especially widespread in the Mediterranean areas and Middle Eastern. Interestingly, in this report, a case with an L3 larva trapped in the human maxillary sinus with other stage larvae is presented.
A 32-year-old female patient has no symptoms until the larva is expelled by sneezing. Endoscopic examination was normal on admission. Paranasal sinus computed tomography (CT) revealed left maxillary sinus soft tissue density. Uncinectomy and middle meatal antrostomy was performed to remove the infection and larvae.
Human ophthalmic and nasopharyngeal myiasis have been documented but asymptomatic maxillary sinus myiasis is unusual and not reported. Due to changes in environmental factors, this atypical infection may occur with an unexpected presentation.
绵羊狂蝇（Oestrus ovis）是一种专性寄生虫，分布于世界各地，尤其是在地中海地区和中东地区广泛存在。有趣的是，在本报告中，我们介绍了一例 L3 幼虫被困在人类上颌窦内，同时还有其他阶段幼虫的病例。
一名 32 岁女性患者在幼虫通过打喷嚏排出之前没有任何症状。入院时，鼻内镜检查正常。鼻窦计算机断层扫描（CT）显示左侧上颌窦软组织密度。行钩突切除术和中鼻道开窗术以清除感染和幼虫。
已记录到人类眼和鼻咽蝇蛆病，但无症状的上颌窦蝇蛆病并不常见，也没有报道过。由于环境因素的变化，这种非典型感染可能会以意想不到的方式出现。
