Clinical & Coding Specifications
Clinical Context
A 34-year-old female seeks elective forehead reduction and hairline lowering for cosmetic concerns about a proportionally large forehead and high hairline. Preoperative evaluation includes history and physical, photographic documentation, informed consent discussing risks (scarring, alopecia, asymmetry), and assessment of hairline position and forehead height. Operative workflow: mark incision at planned hairline, administer local anesthesia with sedation or general anesthesia, perform subgaleal undermining, advance forehead flap with scalp excision, secure with layered closure, and dress the incision. Postoperative care includes wound checks at 48–72 hours, suture removal at 7–14 days, activity restrictions, and follow-up visits at 1 and 3 months to monitor healing and aesthetic outcome.
