Subcision with the Cannula appears to be a safe method with high efficacy in the treatment and high satisfaction in patients as we observed an interesting cure rate (more than 50% after 2 sessions). It demonstrates to be a safe procedure because it performed by single perforation in each side instead of multiple perforations that helps to reduce the patients' pain and risk of scars. In other hand Cannula-based Subcision needs considerable fewer sessions of surgery and also less recovery time.
