Evolution of different forearm flap designs in phalloplasty

Area of Science:

• Reconstructive Plastic Surgery
• Urology
• Microsurgery

Background:

• Phalloplasty is a highly complex reconstructive surgery aiming to create an aesthetically pleasing and functional neophallus.
• Key goals include achieving erogenous sensation, enabling sexual intercourse, and facilitating standing urination via a functional neo-urethra.
• The free forearm flap is the established standard for phallic reconstruction due to its versatility and tissue availability.

Purpose of the Study:

• To review modifications and advancements in free forearm flap designs for phalloplasty.
• To analyze strategies for improving neophallus vascularization and reducing urinary complications like fistulas and stenosis.
• To evaluate the balance between donor site morbidity and recipient site outcomes for optimal patient satisfaction.

Main Methods:

• Review of surgical literature and prominent surgeon contributions to forearm flap phalloplasty.
• Analysis of various flap designs and their modifications.
• Evaluation of reported functional and aesthetic outcomes, including complication rates.

Main Results:

• Multiple modifications to the free forearm flap technique have been developed to optimize outcomes.
• These modifications aim to enhance vascular pedicle length and reliability, and improve urethral integrity.
• Each design presents a unique profile of advantages and disadvantages concerning both donor and recipient sites.

Conclusions:

• Continuous innovation in forearm flap design is crucial for improving phalloplasty results.
• The ongoing refinement of techniques seeks to minimize complications and maximize functional and aesthetic satisfaction for patients.
• Further research into specific flap modifications may lead to standardized, superior outcomes in phallic reconstruction.
