Abstract
Airflow through the nasal passages is crucial for comfortable breathing, conditioning the air we inhale, and maintaining overall health. Limited airflow can cause obstructive sleep apnea, worsen asthma, raise cardiovascular stress, and lead to cognitive issues. Conversely, improving nasal airflow enhances sleep quality, exercise capacity, lung function, and mental well-being. Addressing both anatomical and structural matters, functional rhinoplasty is a key surgical procedure that can restore nasal airflow. This comprehensive review highlights the importance of rhinoplasty in improving both function and appearance by presenting the latest research on how nasal airflow affects physiology and clinical results. It includes patient surveys, such as the NOSE and SNOT-22 scales, as well as objective tests, such as rhinomanometry and acoustic rhinometry. This article explores how nasal airflow impacts overall health by examining airflow physiology, the effects of obstruction, and surgical correction options.
