BACKGROUND
The purpose of this study was to evaluate ranula development according to anatomic variation of the sublingual gland (SLG).
METHODS
We conducted a prospective, consecutive case series considering other clinical conditions. Twenty-five cases treated by SLG excision were enrolled in this study. The ductal structures of the SLGs of another 11 patients undergoing similar surgeries for other conditions were compared.
RESULTS
In 19 of a total of 25 ranulas (76.0%) and 16 of 18 oral nonplunging ranulas (88.9%), the SLG showed an anatomic variation of the main duct called Bartholin's duct structure. Meanwhile, only 3 of 7 plunging ranulas (42.9%) had Bartholin's ducts. Bartholin's duct structure of the SLG was not found in the 11 control cases.
CONCLUSION
Anatomic variation of the ductal system of the SLG might be a possible cause of ranulas. Surgical resection of the SLG is a better treatment choice for ranulas than other, more conservative treatments.
背景
本研究的目的是根据舌下腺（SLG）的解剖变异评估舌下囊肿的发展情况。
方法
我们进行了一项前瞻性的连续病例系列研究，并考虑了其他临床情况。本研究纳入了25例接受舌下腺切除术治疗的病例。比较了另外11例因其他情况接受类似手术的患者舌下腺的导管结构。
结果
在总共25例舌下囊肿中，有19例（76.0%），在18例口腔非深在性舌下囊肿中有16例（88.9%），舌下腺显示出主导管的解剖变异，称为巴氏导管结构。同时，7例深在性舌下囊肿中只有3例（42.9%）有巴氏导管。在11例对照病例中未发现舌下腺的巴氏导管结构。
结论
舌下腺导管系统的解剖变异可能是舌下囊肿的一个可能原因。与其他更保守的治疗方法相比，舌下腺手术切除是治疗舌下囊肿更好的选择。
