Keratocystic odontogenic tumour (KCOT) is considered one of the most aggressive odontogenic lesions presenting high recurrence rate which varies according to treatment modalities employed for management. The treatment rendered should have a lowest possible risk of recurrence and least morbidity while still eradicating the lesion. Although the radical treatment options like enucleation and en bloc resection are associated with lesser recurrences, these can lead to greater morbidity, especially in children with developing teeth and jaw bones, thus, emphasising need to consider more conservative treatment options like decompression and marsupialisation. The purpose of this article was to report the case of an 11-year-old male child with KCOT in the mandibular region associated with impacted premolar treated successfully with decompression and intraoral appliance. After 24 months of follow-up, the spontaneous eruption of premolar was noted with complete resolution of periapical radiolucency. No recurrence was noted even after 5-year follow-up.
牙源性角化囊性瘤（KCOT）被认为是最具侵袭性的牙源性病变之一，其复发率较高，且会因所采用的治疗方式而异。所进行的治疗应具有尽可能低的复发风险和最低的发病率，同时仍能根除病变。尽管诸如摘除术和整块切除术等根治性治疗方法复发率较低，但这些方法可能会导致更高的发病率，尤其是对于正在发育牙齿和颌骨的儿童，因此，强调需要考虑更保守的治疗方法，如减压术和袋形缝合术。本文的目的是报告一例11岁男性儿童下颌区KCOT伴埋伏前磨牙，经减压术和口内矫治器成功治疗的病例。经过24个月的随访，观察到前磨牙自发萌出，根尖周透射区完全消失。即使在5年的随访后也未发现复发。
