舌下腺囊肿的超声诊断研究

摘要

Objective To study the relation between the ranula and mylohyoid muscle, and the ultrasonographic characteristics of the lesions. The significance of ultrasound diagnosis for this disease was probed. Methods Totally 67 cases with ranula underwent ultrasonography. All these lesions were verified by pathology after operation. We made an integrated analysis of the sonograms. Results There were three major types according to the relation with mylohyoid muscle: type 1. oral ranula; type 2, plunge ranula; type 3. mixed ranula. The lesions could be with cystic echoes, blended echoes or hypoechoes. Conclusions Ultrasonography plays an important role in the diagnosis of ranula. and is worthy for treatment.%目的 研究舌下腺囊肿位置与下颌舌骨肌的关系以及超声声像图特点,探讨超声在此类病变诊断中的诊断价值.方法 67例舌下腺囊肿患者均进行超声检查并经术后病理证实.对其声像图资料综合分析.结果 根据舌下腺囊肿的位置与下颌舌骨肌的关系,可分为3型:单纯型、口外型及哑铃型.在声像图上,舌下腺囊肿可表现为囊性回声、囊实性混合回声以及实质低回声.结论 超声检查在舌下腺囊肿的诊断中具有重要作用.
