This drainage decompresses the lesion, reduces internal pressure, and often allows the surrounding bone and tissues to heal gradually.
In dentistry, marsupialization is commonly used for large odontogenic cysts (for example, dentigerous cysts) to shrink
The exact steps vary by site, but the core concept remains: create a cyst wall opening and
Marsupialization can reduce cyst size, preserve vital structures, and lower complication risk compared with immediate complete
