A new preservation technique for dehumping the dorsum

Area of Science:

• Plastic Surgery
• Rhinology
• Facial Plastic Surgery

Background:

• Nasal dorsal hump reduction is a common rhinoplasty procedure.
• Existing techniques may have limitations in preserving dorsal aesthetics and preventing recurrence.
• A novel approach to dorsal hump preservation and reduction is needed.

Purpose of the Study:

• To introduce and evaluate a modified cartilage push-down (Ishida) technique for nasal dorsum dehumping.
• To assess the efficacy and patient/surgeon satisfaction with this modified technique.

Main Methods:

• A modified cartilage push-down technique with bony cap rasping was applied to 300 patients (42 males, 258 females).
• Procedures were closed-surgery primary rhinoplasties involving septal strip resection (low or high).
• The bony cap was shielded and preserved, with the cartilage roof lowered.

Main Results:

• High overall success rates were observed for both low (98% male, 96% female) and high (98% male, 96% female) septal strip resections.
• Patient and surgeon satisfaction correlated with hump size, with high satisfaction reported across all categories.
• The modified technique demonstrated effectiveness, particularly for flat dorsal profiles, reducing the need for extensive camouflage.

Conclusions:

• The modified cartilage push-down (Ishida) technique offers a successful strategy for nasal dorsum dehumping.
• High satisfaction rates among patients and surgeons indicate its potential as a valuable rhinoplasty option.
• This technique may be particularly suitable for patients requiring dorsal hump reduction.
