Sorrin’s operation, a surgical technique for treating a periodontal abscess, used especially when the marginal gingiva appears healthy and provides no access to the abscess. A semilunar incision is made below the abscess area in the attached gingiva, leaving the gingival margin undisturbed. The tissue flap produced by the incision is raised, accessing the abscessed area for curettage, after which the wound is sutured.
