Age-Related Delayed Contour Irregularities After Autologous Rhinoplasty: Mechanisms, Prevention, and Clinical Implications

<jats:p>Background and Objectives: Delayed contour irregularities may occasionally become apparent years after otherwise successful autologous rhinoplasty, particularly in patients with thin nasal skin. While thin-skinned rhinoplasty, autologous graft behavior, and nasal aging have been extensively discussed individually, their potential interaction has received limited attention. This review evaluates current evidence regarding aging-related nasal soft tissue changes, thin skin, autologous graft behavior, and their potential influence on long-term aesthetic outcomes after rhinoplasty. Materials and Methods: A literature review was performed using PubMed, Scopus, and Google Scholar databases. Relevant studies addressing rhinoplasty, autologous cartilage grafts, thin nasal skin, nasal aging, contour irregularities, preservation rhinoplasty, and soft tissue management were reviewed. Original studies, systematic reviews, and clinically relevant review articles were included. The available evidence was critically evaluated with particular attention to long-term outcomes and limitations of current knowledge. Results: Thin nasal skin is a recognized risk factor for graft visibility and contour irregularities following rhinoplasty. Aging-related changes, including dermal thinning, loss of collagen and elastin, decreased skin elasticity, and soft tissue atrophy, may further reduce the ability of the nasal soft tissue envelope to camouflage underlying structural features. However, direct longitudinal evidence linking aging-related soft tissue changes to delayed contour irregularities remains limited. Current literature consists predominantly of retrospective studies, expert opinion, and short- to medium-term outcome analyses. Preservation rhinoplasty and soft tissue camouflage techniques have been proposed to improve contour stability, although their long-term effectiveness in preventing aging-related contour visibility remains uncertain. Conclusions: Current evidence supports the biologic plausibility that progressive soft tissue aging may influence the long-term visibility of underlying grafts after rhinoplasty. Nevertheless, direct clinical evidence remains limited, and the relationship should currently be regarded as a hypothesis-generating concept rather than a proven causal mechanism. Future longitudinal studies incorporating objective assessment of skin quality, soft tissue thickness, and three-dimensional surface imaging are needed to better define the interaction between aging and long-term rhinoplasty outcomes.</jats:p>
