Nasal dorsum fistula is a type of fistula (an abnormal connection between two organs or vessels) that occurs in the nose. It is a rare condition that is caused by trauma or surgery to the nasal dorsum (the bridge of the nose). Symptoms of nasal dorsum fistula include drainage of mucus or pus from the nose, nasal obstruction, and a foul smell. Treatment for nasal dorsum fistula typically involves surgical repair of the fistula.

Symptoms of a nasal dorsum fistula include:

-Nasal congestion
-Nasal discharge
-Foul-smelling breath
-Facial pain
-Headache
-Fever
-Cough
-Sinus pressure
-Difficulty breathing through the nose
-Sensation of a lump in the throat
-Taste changes
-Snoring
-Sleep apnea

Nasal dorsum fistula can be caused by a variety of factors, including trauma, infection, surgery, or congenital defects. Trauma can include facial fractures, blunt force trauma, or lacerations. Infection can be caused by bacteria, viruses, or fungi. Surgery can cause fistulas due to improper technique or tissue damage. Congenital defects can be caused by abnormal development of the nasal septum or other structures in the nose.

1. Surgery: Surgery is the most common treatment for nasal dorsum fistula. The goal of surgery is to close the fistula and restore the normal anatomy of the nose. The type of surgery used will depend on the size and location of the fistula.

2. Antibiotics: Antibiotics may be prescribed to treat any underlying infection that may be causing the fistula.

3. Nasal packing: Nasal packing may be used to help close the fistula and promote healing.

4. Steroid injections: Steroid injections may be used to reduce inflammation and help close the fistula.

5. Laser therapy: Laser therapy may be used to help close the fistula and promote healing.
