Rhinoplasty (nose job)
Normal results include improved breathing and airflow through the nostrils, and an acceptable outward shape of the nose.
The effector of the nose is the muscles that control the movement of the nostrils and the upper lip, allowing for actions like flaring the nostrils or wrinkling the nose. The effector muscles work in response to signals from the brain to adjust the position and shape of the nose.

Human nostrils serve as the primary entry points for air into the respiratory system. When we inhale, air flows through the nostrils, where it is filtered by tiny hairs (cilia) and mucus that trap dust, allergens, and pathogens. The air is then warmed and humidified before passing into the nasal cavity, which contains olfactory receptors that detect odor molecules, allowing us to smell. Additionally, the nostrils can vary in size and shape, which can influence airflow and the efficiency of breathing.
