Anterolateral thigh (ALT) flaps in global reconstructive surgery: A bibliometric analysis

Since the first case in 1984, anterolateral thigh (ALT) flaps have been globally utilized in surgical reconstruction of the head, neck, upper and lower extremities, breast, and phalloplasty, owing to their versatility, reliability, and minimal donor-site morbidity.

This bibliometric study aims to map research trends and knowledge of ALT flaps from January 1, 2004, to April 15, 2024, using the Web of Science Core Collection database. Citespace 6.3.R1 and VOSviewer 1.6.19 were employed to assess the literature and conduct mapping.

We identified 2492 relevant publications, including 2284 original articles and 208 reviews. The analysis reveals a significant rise in ALT flap research, especially after 2017, with contributions from 67 countries and 1730 institutions. China and the USA lead in publication volume and international collaboration, with prominent institutions such as Chang Gung Memorial Hospital and UTMD Anderson Cancer Center at the forefront. Plastic and Reconstructive Surgery is the most cited journal, highlighting its influence in the field. Keyword analysis points to a focus on "anterolateral thigh flap" and "reconstruction," with emerging topics like "phalloplasty" and "vascularized fascia lata."

This study provides a comprehensive overview of the ALT flap research landscape, highlighting key contributions and emerging trends, and sets the stage for future advancements in reconstructive surgery.
