A deviated nasal septum cannot be manually adjusted, as the site of deviation is deep within the nasal cavity and thus inaccessible by hand. A deviated nasal septum is a common and frequent condition encountered in otolaryngology. It mainly results from abnormal nasal septum development during the embryonic stage or from postnatal trauma to the nasal septum and pressure from nasal tumors causing the septum to deviate to one side. After developing a deviated nasal septum, the patient may experience continuous, progressive nasal congestion, as well as facial swelling, pain, and headaches among other symptoms. In severe cases, the deviation may lead to complications such as sinusitis and nasal polyps, which can be diagnosed with an endoscopic examination and sinus CT scan at a hospital. In terms of treatment, minor deviations of the nasal septum do not require intervention. However, if associated symptoms are present, localized surgical correction may be necessary and can be curative.
