Abstract:
BACKGROUND:Rhinoplasty in the elderly requires different surgical approaches due to the morphological and structural changes affecting the nose over time. OBJECTIVES:In this study, the authors aimed to evaluate the age-related cellular and architectural changes of nasal cartilages and soft tissue attachments. METHODS:This prospective study included 80 patients who underwent rhinoplasty. Patients were divided into 2 groups according to age. Group I included 40 patients ranging in age from 19 to 39 years. Group II included 40 patients aged at least 40 years. Samples from nasal cartilages (upper lateral, lower lateral, and septum) and nasal attachments (interdomal, inter-cartilaginous, and septo-crural) were taken. All specimens were evaluated histologically to detect age-related changes. A modified version of the Mankin grading scale was used to score each nasal cartilage sample. All attachment samples were examined by image analysis for quantitative assessment. The results were correlated to preoperative anthropometric measurements of nasolabial angle and nasal projection. RESULTS:Histologically, in group II, the cartilage matrix showed fibrinoid degeneration with a significant decrease in the number of chondrocytes and increased perichondrial fibrosis compared with group I. Attachments in group II showed a lower number of blood vessels and decreased percentage of collagen bundles. Modified Mankin scores were significantly higher in group II, indicating weak cartilages compared with group I. There was negative correlation and significance between projection, nasolabial angle, cartilages, and attachments in study groups. The linear regression model revealed that the lower lateral cartilage is the cartilage that is most affected by the aging process. CONCLUSIONS:These findings not only enhance our current understanding of the natural changes that occur in the nose during aging but may also affect surgical decision-making when grafting or suturing are considered during rhinoplasty. :Level of Evidence: 2.
