Nasal Valve Obstruction Complicating Rhinoplasty: Prevention and Treatment Part I

Intrinsic Nasal Muscles and their Electromyographic Evaluation after External Septorhinoplasty

“…The nasal valve was defined as the region of the nasal airway bounded by the caudal end of the upper lateral cartilages and the septum. An angle less than 10 to 15 degrees at this junction can exclusively cause nasal airway obstruction 11 . The upper lateral cartilage is the only movable part of the valve, whereas the septum is the fixed component 5 .…”

“…This influence can be overcome by utilization of active muscles and recruitment of new muscles that increase the rigidity of the lateral nasal wall and prevent collapse of the nasal valve 4 . Saving the nasal muscle is also important for the prevention of the nasal valve obstruction 11 . The alar and transverse parts of the nasalis muscle and the dilator naris anterior make a group of muscles strongly related to the inspiratory phase of respiration.…”

“…An angle less than 10 to 15 degrees at this junction can exclusively cause nasal airway obstruction. 11 The upper lateral cartilage is the only movable part of the valve, whereas the septum is the fixed component. 5 The greatest concentration of nasal musculature is present at the junction of the upper and lower lateral cartilages.…”

“…4 Saving the nasal muscle is also important for the prevention of the nasal valve obstruction. 11 The alar and transverse parts of the nasalis muscle and the dilator naris anterior make a group of muscles strongly related to the inspiratory phase of respiration. They work synergistically, balancing each other's action to restrain alar compliance during inspiration.…”
