Age- and Gender-Related Variability in Nasal Tip Support

Area of Science:

• Otolaryngology
• Plastic Surgery
• Biomechanical Engineering

Background:

• The age-related changes in nasal tip support are not well-documented.
• Accurate measurement of nasal tip support pressure is challenging.
• The ideal nasal tip support pressure remains undefined.

Purpose of the Study:

• To investigate age and sex-related alterations in nasal tip support pressure.
• To quantify changes in nasal tip resistance across different age demographics.
• To establish normative data for nasal tip resistance based on age and sex.

Main Methods:

• A prospective clinical study involving 159 patients across four age groups (20-29, 30-39, 40-64, >65 years).
• Nasal tip resistance was measured using a digital Newton meter at 2, 3, and 4 mm displacement distances.
• Data analysis focused on comparing nasal tip resistance based on age and sex.

Main Results:

• Nasal tip resistance was significantly higher in the 20-29 age group compared to 30-39 and 40-64 year olds, and also compared to the >65 group at 3 and 4 mm displacement.
• Male subjects exhibited significantly higher nasal tip resistance than females at 3 and 4 mm displacement.
• A significant decrease in nasal tip resistance was observed after age 30.

Conclusions:

• Nasal tip resistance is demonstrably higher in males and declines significantly after the age of 30.
• Nasal tip resistance remains stable in older age groups.
• Rhinoplasty surgeons should consider techniques that augment nasal tip resistance, even in younger patients, to ensure long-term support.
