牙源性囊肿是仅次于根性囊肿的第二大最常见的牙源性囊肿。通常,牙质囊肿是无症状的,通常是偶然诊断的。由于速度慢,扩张性生长的牙质囊肿有可能导致相邻结构脱位(相邻牙齿,后磨牙管),牙根吸收,在极端情况下可能导致颌骨骨折。组织学检查代表一个必要条件,因为其他更令人担忧的病理(牙源性角化囊肿,单囊性成釉细胞瘤,粘液瘤,原始牙源性肿瘤等。)可以在临床和放射学上表现出相似的外观。这个简短的概述旨在说明,通过两个临床病例,考试,膀胱造口术或膀胱切除术的诊断和决策。两种技术的外科手术都以逐步的方式呈现。
The dentigerous cyst is the second most frequent odontogenic cyst after the radicular one. Typically, dentigerous cysts are asymptomatic and are commonly diagnosed incidentally. Due to the slow, expansive growth dentigerous cysts have the potential for dislocation of adjacent structures (neighbouring teeth, canalis retromolaris), root resorptions and in an extreme case could cause jaw fractures. A histological examination represents a sine qua non, because other more alarming pathologies (odontogenic keratocyst, unicystic ameloblastoma, myxoma, primordial odontogenic tumour etc.) can exhibit clinically and radiologically a similar appearance. This brief overview aims to illustrate, by two clinical cases, the examination, the diagnosis and decision-making for either a cystostomy or a cystectomy. The surgical procedure of both techniques is presented in a step-by-step manner.
