Treatment of a plunging ranula with fenestration and continuous pressure.

We present a new method of fenestration and continuous pressure as a simple, effective and uninvasive procedure for the treatment of plunging ranulas. We have recently used in four female patients, aged 10-29 years old. After treatment, the patients remained symptom-free and assessment by magnetic resonance imaging (MRI) showed regression of the ranula in all cases. The procedure resulted in satisfactory healing and we advocate it as a simple and effective treatment that is better for patients than conventional treatment.
