Deviated Nasal Septum
A deviated septum occurs when the thin wall (nasal septum) between your nasal passages is displaced to one side. In many people, the nasal septum is off-center — or deviated — making one nasal passage smaller.
The nasal septum is the centre partitioning between the 2 nasal passages. A crooked nasal septum can lead to breathing disorders with blocked nose. This can even be associated with conditions like obstructive sleep apnea. In some cases, the turbulent airflow generated as a result of the deviated nasal septum can cause dryness and crusting around the septum and can lead to nosebleeds (epistaxis). Uncommonly, a deviated nasal septum can also result in headaches (Sluder’s neuralgia).
Many patients have a deviated nasal septum. If the deviation is mild, it does not require surgical correction, otherwise a septoplasty may be necessary to straighten the crooked nasal septum. In severe cases of crooked nasal septum, a functional septorhinoplasty maybe necessary to straighten the crooked septum. This is especially so if the deviated septum affects the nasal valve area.
