Hydradenectomy is a surgical procedure used to treat hidradenitis suppurativa, a chronic skin condition characterized by painful lumps, abscesses, and inflammation in areas like the armpits and groin. The surgery involves the excision of affected skin and underlying tissue to remove the diseased glands and prevent recurrence. It aims to alleviate symptoms, reduce the frequency of flare-ups, and improve the patient's quality of life. Depending on the severity, the procedure may vary in extent from small excisions to more extensive surgeries.
