Keratocystic odontogenic tumor (KCOT) is a benign odontogenic tumor with an aggressive behavior and high recurrence rate. The most common site of predilection is the posterior mandible. In contrast, KCOTs occurring in the maxillary region are relatively rare. However, the maxillary involvement poses a greater and increased threat, due to proximity to vital structures such as maxillary sinus, orbital floor, and infratemporal fossa. This report presents such a case of KCOT involving the maxillary sinus eroding the floor of the orbit and provides an account of the factors that need to be considered during management.
牙源性角化囊性瘤（KCOT）是一种具有侵袭性且复发率高的良性牙源性肿瘤。最常见的好发部位是下颌骨后部。相比之下，发生在上颌区域的KCOT相对少见。然而，由于上颌区域靠近上颌窦、眶底和颞下窝等重要结构，该部位受累会带来更大且不断增加的威胁。本报告介绍了这样一例累及上颌窦并侵蚀眶底的KCOT病例，并阐述了治疗过程中需要考虑的因素。
