Linear Scarification.—The parts are thoroughly cross-tracked, cutting through the diseased tissue, and subsequently a simple salicylated ointment applied. The operation is repeated from time to time, and as a result the new growth undergoes retrogressive changes, and cicatrization takes place.
Punctate Scarification.—By means of a simple or multiple-pointed instrument numerous closely-set punctures are made, and repeated from time to time, usually with the same action and result as from linear scarification.
Erasion.—The parts are thoroughly scraped with a curette, and a supplementary caustic application made, either with caustic potash or several days' use of the pyrogallic-acid ointment. The result is usually satisfactory.
The dental-burr is also useful in breaking up discrete tubercles.
Excision.—This is an effective method if the disease consists of a small pea- or bean-sized circumscribed patch.
Of these various operative methods those now most favored are erasion and excision, punctate and linear scarification methods are now rarely employed.
