Modified trilobed transposition flap for a distal nasal defect.

Area of Science:

• Plastic Surgery
• Reconstructive Surgery

Background:

• Reconstructing distal nasal defects presents challenges due to limited skin mobility and risk of nasal alar retraction.
• Conventional trilobed flaps may be suboptimal for distal defects, potentially causing flap immobility and margin distortion.

Purpose of the Study:

• To evaluate the efficacy of a modified trilobed flap for treating distal nasal defects.
• To assess the functional and aesthetic outcomes of this modified flap technique.

Main Methods:

• A modified trilobed flap design was employed, extending flap bases and tips further from the pivot point.
• The technique was applied to 15 consecutive cases of distal nasal defects between January 2013 and December 2019.
• Follow-up averaged 15.6 months.

Main Results:

• Complete flap survival was observed in all 15 cases.
• Satisfactory aesthetic outcomes were achieved.
• No complications, including wound dehiscence, nasal asymmetry, or hypertrophic scarring, were reported.

Conclusions:

• The modified trilobed flap is a simple, reliable, and effective surgical option for distal nasal defect reconstruction.
• This technique addresses the limitations of conventional flaps, offering improved outcomes.
