Extranasal applications of the bilobed flap

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Dermatologic Surgery

Background:

• The bilobed flap is a recognized technique for reconstructing defects of the distal nose.
• Understanding its mechanics and geometry is crucial for reproducible results.
• Its application to extranasal reconstruction offers novel design flexibility with reduced risk of secondary tissue distortion.

Purpose of the Study:

• To describe the experience with extranasal applications of the bilobed flap.
• To demonstrate the utility of this reconstructive technique in various extranasal locations.

Main Methods:

• General technique of the bilobed flap is detailed, focusing on extranasal variations.
• Five distinct anatomic locations are presented with specific considerations.
• Photographic documentation illustrates the technique and outcomes.

Main Results:

• Extranasal bilobed flap reconstruction allows for lobule size variance, minimizing secondary tissue distortion.
• Careful flap design aligning incisions with relaxed skin tension lines is essential.
• Meticulous suturing techniques are vital for camouflaging the flap's complex suture line.

Conclusions:

• The study advocates for expanding the use of the bilobed flap to extranasal sites.
• This versatile flap yields functional and aesthetic results comparable to its nasal applications.
• The technique provides a valuable option for complex extranasal defect reconstruction.
