Definition
The Abbe‑Estlander operation, also referred to as the Abbe‑Estlander flap, is a reconstructive plastic‑surgical technique used to repair full‑thickness defects of the lip, particularly those involving the vermilion and cutaneous portions. It employs a cross‑lip (or “lip switch”) flap that transfers tissue from the opposite lip while preserving the labial artery, thereby restoring both function and aesthetics.
Historical background
- Robert Abbe (1851–1928), an American surgeon, first described the cross‑lip flap in 1898 for central lip reconstruction.
- Carl Estlander (1885–1961), a Swedish plastic surgeon, later modified Abbe’s technique to address lateral lip and commissure defects, emphasizing the use of the labial artery as the flap’s vascular pedicle.
The combined nomenclature “Abbe‑Estlander” acknowledges both contributions and is commonly used in contemporary surgical literature.
Indications
- Full‑thickness defects of the central or lateral lip up to approximately one‑third of the horizontal lip length.
- Reconstruction of lip commissure defects where both vermilion and cutaneous tissue are missing.
- Cases where a single‑stage local flap is preferred over grafts or distant flaps, and where the opposite lip has adequate tissue reserve.
Surgical technique (overview)
- Pre‑operative planning – Measurement of the defect; assessment of the donor lip’s vascularity and tissue quality.
- Flap design – A rectangular or isosceles‑triangular full‑thickness flap is outlined on the donor lip, centered over the labial (inferior) artery.
- Incision and elevation – The flap is incised through skin, muscle, and mucosa, then elevated while preserving the arterial pedicle.
- Transfer – The flap is rotated or transposed across the oral commissure to the recipient site, suturing the vermilion and cutaneous edges precisely.
- Donor site closure – The donor lip is primarily closed in layers to re‑approximate the musculature and skin.
- Staging – The flap is typically divided after 10–14 days in a second minor operation (the “stage‑two” procedure), separating the donor and recipient lips while maintaining vascular continuity until then.
Variations
- Estlander flap – A modification that incorporates a portion of the oral commissure to reconstruct lateral lip defects.
- Modified Abbe flap – Utilized for larger central defects by extending the flap width or combining with mucosal grafts.
Outcomes and complications
- High rates of functional restoration (sphincteric competence, oral continence) and satisfactory aesthetic results when performed by experienced surgeons.
- Potential complications include flap necrosis (rare when the arterial pedicle is preserved), sensory loss, lip asymmetry, and donor‑site morbidity such as scar contracture.
- Long‑term follow‑up studies report stable results with minimal functional deficit.
Current relevance
The Abbe‑Estlander operation remains a cornerstone of lip reconstruction in both trauma and oncologic surgery. It is taught in plastic‑surgery residency programs and referenced in major surgical textbooks, including Grabb and Smith’s Plastic Surgery and Plastic and Reconstructive Surgery: Principles and Practice.
