A 30-year-old patient is diagnosed with a symptomatic second branchial cleft cyst that has recently become infected, causing pain and swelling. After initial antibiotic treatment to control the infection, what is the definitive management for this condition?

Explanation

While antibiotics can manage acute infection and incision and drainage might provide temporary relief, the definitive treatment for a branchial cleft cyst is complete surgical excision. This is crucial to prevent recurrence, especially if a sinus tract is present, and to avoid potential complications like repeated infections or, rarely, malignant transformation. In cases of acute infection, surgery is typically delayed until the acute inflammation subsides.
