These include conservative procedures such as marsupialization, enucleation, enucleation with
chemical cauterization and/ or peripheral ostectomy to aggressive treatments such as resection.
Out of 35 perforations, 18 were subjected to
chemical cauterization and 17 to freshening and application of Gelfilm patch and platelet rich plasma.
In this study we found that
chemical cauterization is easy to perform as compared to electrocautery in which special equipment and better expertise is required, many other studies also support these observations14.
Chemical cauterization with 10% povidone iodine with 50% salicylic acid (7) (SOR: B), 10% potassium hydroxide (8) (SOR: B), cantharidin (2) (SOR: C), or 25% to 50% trichloroacetic acid (6) (SOR: C) is also effective.
The principle of
chemical cauterization is that when on application, it breaks up fibrosis, promotes granulation and new tissue formation at the margin of the perforation.
A physician may occasionally perform
chemical cauterization of granulation tissue; examples include cauterization at the base of an umbilical stump in a newborn or on the vaginal cuff after hysterectomy.
Brisk bleeding from the site of attachment was checked by
chemical cauterization with Trichlor Acetic Acid.
