Mucocoeles of the lip are very common. They usually occur on the lower lip in the moist skin just on the inside of the mouth. The theory here is that a small mucous producing duct has become blocked and the saliva cannot be expelled out into the mouth and so builds up in a small cyst. These cysts can often resolve spontaneously however if they have been there for more than 6 months they are probably unlikely to do so and surgical excision is recommended.
No specific Post-operative care is necessary. Eat and drink normally.
