Plunging ranula (22)

The ranula smoulderling for a long time

This patient was occured ranula five years ago. Several months after,  it spontaneously became small. Afer that,  it was smoulderling as an small submandibular swelling for a long time. 5 years after occurrence,  he came to me to be treated from other prefecture.

This is a course of treatment of this patient. I injected 1 KE of OK-432 to him. The next day, his ranula s swollen and the skin became red.  This means good response. One week after, his ranula was still swollen. 2 weeks after treatment, his ranula began to shrink. 6 weeks after treatment, there was no swelling at his left neck.
