Histological and Anthropometric Changes in the Aging Nose

Area of Science:

• Otolaryngology
• Plastic Surgery
• Aging Research

Background:

• Rhinoplasty in elderly patients presents unique challenges due to age-related nasal structural modifications.
• Understanding these changes is crucial for optimizing surgical techniques in older individuals.

Purpose of the Study:

• To investigate the cellular and architectural alterations in nasal cartilages and their soft tissue attachments associated with aging.
• To correlate these age-related changes with anthropometric nasal measurements.

Main Methods:

• A prospective study involving 80 rhinoplasty patients, divided into two age groups (19-39 and ≥40 years).
• Histological examination of nasal cartilages (upper lateral, lower lateral, septum) and attachments (interdomal, inter-cartilaginous, septo-crural).
• Quantitative assessment using a modified Mankin grading scale for cartilage and image analysis for attachments, correlated with nasolabial angle and nasal projection.

Main Results:

• Older patients (≥40 years) exhibited cartilage matrix degeneration, reduced chondrocytes, and increased fibrosis compared to younger patients.
• Nasal attachments in older individuals showed fewer blood vessels and less collagen.
• Higher modified Mankin scores in the older group indicated weaker cartilages, with the lower lateral cartilage most affected by aging.

Conclusions:

• Aging leads to significant histological changes in nasal cartilages and attachments, characterized by degeneration and reduced structural integrity.
• These findings provide critical insights into age-related nasal alterations, potentially influencing surgical strategies in rhinoplasty for the elderly.
