Many anatomical variations of the middle turbinate (MT), including pneumatized, paradoxically curved, bifurcate, trifurcate, secondary, and accessory, have been described. The most common is pneumatized MT (concha bullosa), but other less common variations may also impact the outcome of clinical management. Anatomical variations of the MT, particularly with a concomitant deviated nasal septum, tend to obstruct the middle meatus leading to disruption of the normal sinus drainage and worsening the symptoms of rhinosinusitis. By recognizing the unique anatomical variant by endoscopy or imaging will help us to improve the management. We report an endoscopic presentation of a rare accessory MT.
中鼻甲（MT）有许多解剖学变异，包括气房性、反常性弯曲、分叉、三分叉、次级和副性等。最常见的是气房性 MT（泡状鼻甲），但其他较少见的变异也可能影响临床处理的结果。MT 的解剖学变异，特别是合并鼻中隔偏曲时，往往会阻塞中鼻道，导致正常鼻窦引流受阻，加重鼻窦炎的症状。通过内镜或影像学识别独特的解剖变异有助于改善治疗。我们报告了一例罕见的副性 MT 的内镜表现。
