Indicated treatment for infections that result in a collection of purulent material in a circumscribed and closed cavity.

• A. Blunt dissection
• B. Incision&Drainage
• C. Excision
• D. Reduction Incision

Answer: (B)

When infection forms a pus-filled collection in a closed space, the essential step is to create an opening to let the material drain. Incision and drainage accomplish this by cutting into the lesion to evacuate the purulent material, relieve pressure, and convert a contained pocket into an open pathway for ongoing drainage. This directly addresses the source of infection within the cavity and often improves antibiotic effectiveness and healing, sometimes with a drain left in place to prevent reaccumulation.

Other approaches don’t target drainage of the collection: blunt dissection is about separating tissues and isn’t a reliable way to evacuate pus; excision removes tissue rather than addressing the purulent collection; reduction incision isn’t a standard method for managing an abscess.
