Nasal Skin Thickness Measurements Using Computed Tomography in an Adult Saudi Population

Area of Science:

• Plastic Surgery
• Anatomy
• Medical Imaging

Background:

• Nasal skin thickness is a critical, yet understudied, factor influencing rhinoplasty outcomes.
• Accurate pre-operative assessment of nasal skin thickness is essential for surgical planning.

Purpose of the Study:

• To quantify nasal skin thickness at key aesthetic points.
• To highlight the importance of nasal skin thickness in rhinoplasty success.

Main Methods:

• Computed tomography (CT) scans were used to measure nasal skin thickness in 60 patients.
• Measurements were taken at four aesthetic locations: nasion, rhinion, nasal tip, and columella.
• Hounsfield unit measurements were performed using specialized in-house software.

Main Results:

• Mean nasal skin thickness: nasion (3.96 mm), rhinion (1.86 mm), nasal tip (3.32 mm), columella (3.32 mm).
• The nasion exhibited the thickest skin, while the rhinion had the thinnest.
• A statistically significant difference in columellar skin thickness was noted between genders (P=0.016).

Conclusions:

• Nasal skin thickness varies significantly across different facial regions.
• These quantitative data provide valuable insights for surgeons to tailor rhinoplasty techniques to individual patient anatomy.
• Considering patient-specific nasal skin thickness can enhance surgical planning and improve rhinoplasty results.
