Succinct key points
- GM is a troublesome disease with vague symptoms and hard to eradicate
by conservative treatment.
- Most of the GM cases had previous otologic surgery history, and the
most common symptom was otorrhea.
- Mention to the recurrence of GM, CO2 laser and causative agents had
comparable results.

be apply only on minor and fresh symptom cases.
