Intralesional steroid injection with either a syringe or an automatic needleless injector usually decreases the size of draining sinuses. The injection of 0.05-0.25 mL of triamcinolone acetonide suspension (2.5-10 mg/mL) into each lesion (up to 3-6 mL per visit) is recommended for its anti-inflammatory effects. This treatment can be repeated every 2-3 weeks if necessary. [84] These injections should be avoided if there is clinical evidence of infection. [2]
