Optimizing Gynecomastia Correction Surgery: Efficacy and Safety of Tumescent Local Anesthesia Approach

BackgroundTumescent local anesthesia (TLA) involves infusing a saline solution containing lidocaine and epinephrine into tissues to achieve localized anesthesia and vasoconstriction. While liposuction under general anesthesia remains the most used treatment, we introduce a novel TLA approach for gynecomastia surgery, drawing from our extensive experience in recent years.MethodsBetween the years 2010 and 2023, we performed gynecomastia surgery on 60 male patients under TLA. The gynecomastia was treated by liposuction plus periareolar excision technique. Liposuction was carried out on both breasts in every case, regardless of whether the gynecomastia was bilateral or unilateral. The tumescent solution consisted of 25 mL of 2% lidocaine, 8 mEq of sodium bicarbonate, and 1 mL of epinephrine (1 mg/1 mL) in 1000 mL of 0.9% saline solution. The solution was infiltrated between the pectoral fascia and the mammary gland, and then the surgery was carried out.ResultsThe average volume of tumescent solution infiltrated during TLA was 300 mL per breast. There were no reports of adrenaline or lidocaine toxicity, and no cases required a conversion to general anesthesia. Patients experienced no pain or discomfort during the preoperative infiltration or surgical procedure. We observed a major postoperative complications rate of 6.7%, represented by three incident of hematoma and one case of seroma. A minor complication rate of 5% was observed: two cases of retraction of the NAC and one case of gynecomastia recurrence, the latter undergoing an additional combination procedure with liposuction and subcutaneous mastectomy. Follow-up time ranged from 30 days to 1 year.ConclusionsWe developed a new outpatient surgical method for gynecomastia using liposuction and periareolar excision under tumescent local anesthesia. This technique, supported by a comprehensive rehabilitation plan, proved a successful and quick recovery, and high patient satisfaction. Our results suggest it is a feasible and effective option, warranting further consideration in gynecomastia treatment strategies.Level of Evidence IVThis journal requires that authors assign a level of evidence to each article.
