Anatomical variations of the nasal turbinate, such as secondary middle turbinate (SMT) and bifid inferior turbinate (BIT), are sporadic. In most cases, SMT and BIT are generally bilateral. Moreover, the uncinate process is unusual in BIT because it is widely acknowledged that BIT could be an abnormality of the uncinate process. However, we found an unusual case of a 19-year-old female with 2 compartments on the right nostril since birth. CT scan and nasal endoscopy revealed unilateral SMT and ipsilateral BIT with the presence of an uncinate process. Therefore, considering the different origins of the uncinate process and inferior turbinate, BIT with the uncinate process can be referred to as true BIT, while BIT without the uncinate process can be referred to as false, double, or accessory inferior turbinate.
鼻甲骨的解剖变异，如继发中鼻甲（SMT）和双裂下鼻甲（BIT），较为少见。在大多数情况下，SMT和BIT通常是双侧的。此外，在BIT中钩突异常，因为普遍认为BIT可能是钩突的一种异常情况。然而，我们发现了一例不同寻常的病例，一名19岁女性自出生以来右侧鼻孔有两个腔室。CT扫描和鼻内镜检查显示为单侧SMT和同侧BIT，并伴有钩突。因此，考虑到钩突和下鼻甲的不同起源，伴有钩突的BIT可称为真性BIT，而不伴有钩突的BIT可称为假性、双侧或副下鼻甲。
