Alarplasty and its effects on respiratory function: a cross-sectional study

Background Alarplasty is a cosmetic procedure modifying nostril dimensions, but its long-term physiological effects on pulmonary function remain unclear. This study assessed pulmonary parameters to explore potential functional implications. Methods A cross-sectional study included 22 women who had undergone alarplasty at least two years prior. Spirometry measured FEV1, FVC, and FEV1/FVC ratio. Respiratory muscle strength was evaluated using maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). Results were compared to predicted normative values, and correlations with time since surgery were analyzed. Results FEV1 predicted % and FEV1/FVC ratio were significantly lower than expected ( p < 0.05), suggesting airflow limitations. MIP and MEP were also reduced ( p ≤ 0.005), indicating weaker respiratory muscles. A significant negative correlation was found between years since surgery and FEV1 ( p = 0.002), FVC ( p = 0.0001), and FEV1 predicted % ( p = 0.0002). Conclusion Previous alarplasty may be associated with differences in pulmonary function parameters. Further studies with larger samples are needed to confirm these findings.
