Deviated nasal septum (Bent or crooked nasal septum)

Causes

A deviated septum can be present since birth (congenital) or result from injury to the nose. Some risk factors include genetic predisposition and trauma, such as a blow to the face, which is common in contact sports or accidents.

This condition is prevalent, with many individuals having some degree of deviation. However, not all cases are symptomatic or require treatment, making accurate prevalence rates challenging to ascertain.

Symptoms and Impact on Health

Common Symptoms

The most noticeable symptom of a deviated septum is having difficulty breathing through the nose, which is often more pronounced on one side. Other symptoms include recurrent sinus infections, nosebleeds, facial pain, headaches, and snoring.

Long-Term Health Implications

If left untreated, a severe case of deviated septum can lead to chronic sinusitis, sleep disturbances including snoring and sleep apnea, and a significant impact on life quality due to constant nasal obstruction and discomfort.

Diagnosis of Deviated Nasal Septum

Clinical Evaluation

Diagnosing a deviated septum involves a thorough medical history and a physical examination. Our otolaryngologist (i.e. ear, nose and throat specialist), Dr Ker Liang will inspect the nasal passages, often using a bright light and sometimes a nasal speculum, as well as perform a naso-endoscopy, to open up the nostrils for a detailed view.

In addition to a physical examination, diagnostic tools such as nasal endoscopy and imaging studies (like CT scans) can produce detailed images of the nasal anatomy to confirm the diagnosis and plan treatment.
