Summary of Local Flaps in Facial Reconstruction
Local Flaps in Facial Reconstruction: Your Comprehensive Guide
Introduction
Ear and lip plastic surgery addresses the reconstruction and resurfacing of perioral and auricular regions following trauma, tumors, or congenital defects. This material specifically focuses on surgical techniques for covering lower lip and ear defects, including the use of tongue flaps, postauricular flaps, and tissue expanders. The aim is to provide an overview of indications, flap planning, surgical steps, and expected outcomes.
Key Concepts
Resurfacing: Surgical coverage of a surface defect (skin or mucous membrane) using a free graft or flap.
Flap: Vascularized autologous tissue transferred to a defect via a pedicle; it can be local, regional, or free (microsurgical).
Pedicle: The vascular stalk of a flap, providing perfusion to the transferred tissue.
Lower Lip Resurfacing Using a Lingual Flap
Principle
- Utilizing a flap from the tongue to cover larger lip defects, especially when there is insufficient adjacent skin or mucosa.
- The lingual flap maintains a reliable vascular supply and is well-suited for resurfacing the inner surface layer of the lip.
Indications
- Vascular malformations of the lower lip, larger tumor resections, impaired healing following previous procedures.
Planning and Surgical Technique
- Delineation of the defect and planning of the flap on the undersurface of the tongue.
- Design of a central pedicle with sufficient muscle and submucosal volume for perfusion.
- Resection of pathological tissue from the lip.
- Transfer and suturing of the flap to the lip to restore mucosal continuity and cover the defect.
- After healing (often one to several months), the pedicle may be revised or, if the plan requires it, separated.
Clinical Example

- Image (B) plan for a lingual flap from the undersurface of the tongue.
- Image (C) flap sutured to the lip after resection.
- Image (D) result after 2 years - long-term function and aesthetics.
Advantages and Disadvantages
| Advantage | Disadvantage |
|---|---|
| Well-vascularized coverage | Temporary speech and swallowing difficulties |
| Similar mucosal texture | Requires a two-stage procedure for certain flap types |

Postauricular Flap for Ear Defect Reconstruction
Principle
- The postauricular flap utilizes skin and subcutaneous tissue behind the ear (mastoid region) to cover defects of the auricle, especially the anterior concha and ear rim.
Indications
- Defects following resection of skin tumors (e.g., squamous cell carcinoma) in the ear region, especially on the upper or marginal rim.
Planning and Technique
- The defect on the auricle is precisely measured.
- The postauricular flap is designed to have sufficient width and length to cover the defect.
- The flap is often cutaneous or fasciocutaneous, with appropriate undermining for mobilization (dissection to ensure laxity).
- The flap is rotated/inset into the defect and sutured to its margins.
- After healing, the pedicle can be divided and definitively refined, if necessary.
Special Procedure: Skin Grafting for Gaps
- If a gap forms between the flap and the ear, this can be most easily covered with a skin graft harvested from the postauricular region inferior to the defect. This graft is typically well-tolerated, and the donor site can be primarily closed.
Example Surgical Steps (Illustration)
- (A) Defect of the superior ear following resection of squamous cell carcinoma.
- (B) Design of the postauricular flap.
- (C) Flap raised and inset.
- (D) Appearance before pedicle division.
- (E) Status after pedicle division.
- (F) Long-term appearance.
