Summary
Transoral excision of the sublingual gland is an effective first-line treatment for plunging ranula. This surgical approach demonstrated a low recurrence rate and manageable complications in a large case series.
Area of Science:
- Otolaryngology
- Oral and Maxillofacial Surgery
- Surgical Oncology
Background:
- Plunging ranula is a cystic lesion originating from the sublingual gland, often requiring surgical intervention.
- Diverse treatment modalities exist for ranula, with varying degrees of success and complication rates.
Purpose of the Study:
- To review the experience with plunging ranula treatment.
- To evaluate the efficacy of transoral sublingual gland excision as the primary treatment modality.
Main Methods:
- Retrospective chart review of 95 consecutive plunging ranula cases treated between January 2001 and February 2010.
- Surgical treatment involved transoral excision of the sublingual gland and ranula evacuation.
- Literature search conducted using MEDLINE and OLD MEDLINE databases.
Main Results:
- Eighty-one patients underwent transoral sublingual gland excision with a mean operating time of 75.3 minutes.
- One recurrence was observed, requiring sublingual gland remnant excision.
- Two cases had minor trauma to the submandibular duct, necessitating submandibular gland excision; other complications were minor and transient.
Conclusions:
- Transoral sublingual gland excision is a safe and effective first-line treatment for plunging ranula.
- This approach offers a low recurrence rate and acceptable complication profile.
- The study contributes significant data to the reported cases of plunging ranula globally.

Urinary Tract Calculi VI: Surgical Management
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
