This is our results of OK-432 therapy for ranula  till April 2008.

This is overall our result till August 2013.

OK-432 therapy is very effective for pseudocysts (without epithelium) such as ranula, lingual cyst and othematoma, and cysts with monolayer epithelium such as lymphangioma and median cervical cyst.
Lateral cervical cyst has squamous epitheliuim. So, the effect of OK-432 is uncertain.
