Dorsal Preservation Surgery: A Novel Modification for Dorsal Shaping and Hump Reduction

Area of Science:

• Plastic Surgery
• Otolaryngology
• Facial Plastic Surgery

Background:

• Recurrent dorsal hump deformity is a common complication following traditional rhinoplasty.
• Existing techniques for dorsal hump reduction can lead to undesirable aesthetic outcomes and functional issues.

Purpose of the Study:

• To introduce and evaluate a novel dorsal roof flap (DRF) technique for rhinoplasty.
• To assess the efficacy of the DRF technique in modifying the nasal hump and dorsum while minimizing morbidity and recurrence.

Main Methods:

• The study involved 25 patients undergoing primary or secondary rhinoplasty.
• Two types of nasal DRF (cartilaginous or osseocartilaginous) were utilized based on hump composition.
• The procedure involved creating a triangular flap, lowering the nasal profile, and suturing the flap to the upper lateral cartilages.

Main Results:

• The mean follow-up period was 10.3 months.
• No complications or revisions were reported in any of the patients.
• The DRF technique was successfully applied to various hump compositions (cartilaginous, bony, combined).

Conclusions:

• The dorsal roof flap technique offers a method for dorsal preservation rhinoplasty.
• This technique effectively eliminates the dorsal hump while preserving nasal structures.
• The DRF approach demonstrates potential in minimizing the recurrence of dorsal hump deformities.
