Transoral Robotic Surgery with Sialendoscopy for a Plunging Ranula.

BACKGROUND/AIMS: Plunging ranulas are oral mucoceles that often cannot be visualized directly and thus can be challenging to diagnose and differentiate from other neck lesions. Surgery is the preferred treatment option, but the optimal approach requires careful consideration.

METHODS: We report the case of a plunging ranula presenting as an isolated neck mass in a 33-year-old patient. This patient was treated with a novel transoral robotic surgery (TORS)-assisted approach aided by sialendoscopy.

RESULTS: TORS allowed for exceptional visualization and access to the plunging ranula and sublingual gland while avoiding critical neurovascular structures. The patient healed well without recurrence or complications.

CONCLUSION: The TORS approach with sialendoscopy for plunging ranulas described in this case report shows promise and should be considered for certain clinical presentations. Additional studies evaluating the effectiveness of TORS for plunging ranulas may be indicated.
