The keratocystic odontogenic tumour (KCOT), formerly known as the odontogenic keratocyst, is a benign intra-osseous odontogenic tumour. The KCOT is characterised by a potential for locally destructive behaviour and a relatively high recurrence rate. Most KCOT are incidentally discovered as well-defined unilocular or multilocular radiolucencies on routine panoramic radiographs.
A 15-year-old boy was referred to dental care with a non-syndromic KCOT in the right angle of the mandible. Using cone-beam computed tomography (CBCT) as a diagnostic instrument for precise assessment of the KCOT, the exact location of the lesion was determined.
The cystic formation was enucleated without peripheral ostectomy.
FOLLOW-UP: At post-operative follow-up after 3 and 6 months, the boy reported no pain and there was no residual swelling or fracture. Imaging was planned after 1 year to decide whether further surgical treatment is indicated.
The CBCT is considered beneficial in cases of cystic formations to determine the localisation and borders of the lesion in all three dimensions.
角化囊性牙源性肿瘤（KCOT），以前称为牙源性角化囊肿，是一种良性骨内牙源性肿瘤。KCOT的特点是具有局部破坏性行为的可能性和相对较高的复发率。大多数KCOT是在常规全景X线片上偶然发现为边界清晰的单房或多房透射区。
一名15岁男孩因右下颌角非综合征性KCOT转诊至牙科治疗。使用锥形束计算机断层扫描（CBCT）作为精确评估KCOT的诊断工具，确定了病变的确切位置。
囊肿形成物被摘除，未进行周边骨切除术。
术后3个月和6个月随访时，男孩报告无疼痛，无残留肿胀或骨折。计划在1年后进行影像学检查，以决定是否需要进一步的手术治疗。
CBCT被认为在囊性肿物病例中有助于从三维角度确定病变的位置和边界。
