We have treated seven patients with a plunging ranula during the past 10 years. All patients underwent surgery via a cervical approach. In two, the ranula reached the anterior neck by passing through a dehiscence in the mylohyoid muscle, while in the other five the plunging ranula passed posteriorly to the mylohyoid muscle. A pseudocyst was extirpated in each patient. Although total sublingual gland excision was not performed in two patients, no recurrence was observed in any patient. Incision of the pseudocyst facilitated subsequent procedures and decreased the incidence of transient facial paralysis. In the presence of a cervical mass without swelling of the oral floor, a cervical approach may still be the method of choice either for the first operation or for salvage surgery after recurrence subsequent to intraoral procedures. It is based on the fact that there may be ectopic sublingual glands residing on the inferior surface of the mylohyoid muscle.
在过去10年里，我们共治疗了7例坠入性舌下囊肿患者。所有患者均通过颈部入路接受手术。其中2例，舌下囊肿经颏舌骨肌裂开处延伸至颈前部，而另外5例坠入性舌下囊肿则经颏舌骨肌后方延伸。每例患者均切除了一个假性囊肿。虽然有2例患者未行舌下腺全切术，但所有患者均未复发。假性囊肿切开有助于后续操作，并降低了暂时性面瘫的发生率。对于存在颈部肿物而口底无肿胀的患者，无论是首次手术还是口腔内手术后复发的挽救性手术，颈部入路仍可能是首选方法。这是基于颏舌骨肌下表面可能存在异位舌下腺这一事实。
