Aims and objectives: (1) To study the effectiveness of ultrasound guided aspiration of breast abscess in management of breast abscess. (2) To study the effectiveness of incision and drainage of breast abscess in management of breast abscess. (3) To compare the effectiveness and outcome of ultra-sonography guided needle aspiration with incision and drainage in management of breast abscess in terms of procedure time, healing time, hospital stay, post-operative pain and cosmetic output. Material and methods: A prospective study was conducted at Sheth L.G Hospital, Maninagar, Ahmedabad. Among these 60 patients, 30 had undergone aspiration of the breast abscess (group A) and 30 had undergone incision and drainage of the breast abscess (group B). Results and conclusion: Our study Ultra Sonographic guided needle aspiration is superior to incision and drainage in term of Hospital Stay Time, Procedure Time, Cosmetic Output and Post Operative Pain; Needle aspiration doesn’t require any kind of anesthesia so patient can be managed OPD based also. Some patients don’t respond to multiple aspiration, so they were managed with incision and drainage
