Appendectomy Scars: Open vs. Laparoscopic Appearance & Healing Factors

Scar Characteristics by Approach

Approach	Incision	Typical Scar Length	Location	Visibility
Open Appendectomy	McBurney (oblique) or midline	2–4 inches (5–10 cm)	Right lower quadrant	More noticeable; may widen
Laparoscopic	3 ports (10 mm umbilical, 2×5 mm)	3–10 mm each	Umbilicus (hidden), LLQ, suprapubic	Minimal; often barely visible at 1 yr

Healing Timeline

• 0–2 wks: Inflammatory; red, raised, firm.
• 2–8 wks: Proliferative; collagen remodeling, still pink.
• 3–12 mos: Maturation; flattens, fades to white/silvery.
• Keloid/Hypertrophic Risk: Genetic, darker skin, tension across joints. Silicone gel/sheets, steroid injection if needed.

Factors Influencing Final Appearance

• Surgical technique (subcuticular vs. staples).
• Infection / dehiscence.
• Patient age, nutrition, smoking, diabetes.
• Sun exposure (UV darkens scars → sunscreen 1 yr).

Scar Optimization

• Silicone gel/sheeting (12+ hrs/day × 3–6 mos).
• Gentle massage after epithelialization (2–3 wks).
• Sun protection (UPF clothing, SPF 50+).
• Early treatment of hypertrophy.

Most laparoscopic scars become nearly invisible; open scars fade significantly but remain palpable.
