The anatomy of the nasal cavity and the paranasal sinuses is complex. After widespread use of endoscopes and computed tomography, many variations have been described. Secondary and accessory middle turbinates (AMTs) can mimic the real middle turbinate. These variations may arise during embryological development. I believe that detailed knowledge of anomalies of the sinonasal tract is critical for successful management, and important in enabling the surgeon to perform safe surgery. Failure to recognize the variants could lead to inadvertent damage to the orbital lamina papyracea during surgery. Knowledge and correct description of anatomical variations of the turbinates by use of computed tomography images will aid achievement of correct diagnosis and surgical management and avoidance of potential complications during endoscopic procedures. To the best of my knowledge, this is the first report in the world literature of sinusitis caused by first and second secondary middle turbinates co-existing with an AMT.
鼻腔和鼻窦的解剖结构非常复杂。随着内窥镜和计算机断层扫描的广泛应用，已经描述了许多变异。二级和辅助中鼻甲（AMT）可以模拟真正的中鼻甲。这些变异可能发生在胚胎发育过程中。我认为，详细了解鼻窦道的异常对于成功治疗至关重要，对于外科医生进行安全手术也非常重要。如果未能识别这些变异，可能会导致手术过程中眶纸板无意中受损。通过使用计算机断层扫描图像了解和正确描述鼻甲的解剖变异，将有助于正确诊断和手术管理，并避免内窥镜手术中的潜在并发症。据我所知，这是世界文献中首次报道由第一和第二二级中鼻甲与 AMT 并存引起的鼻窦炎。
