Q

What is the medical treatment of nasal polyps?

A

Oral and nasal steroids

Traditional polypectomy

Microdebrider

Endoscopic sinus surgery

Recurrence

What is Chronic adult rhinosinusitis?

A

Duration of sysmptoms >12 weeks
– Persistent inflammatory changes on imaging >4 weeks
after starting appropriate therapy

What is hereditary haemorrhagic telangiectasia? (HHT)

A

A rare autosomal dominant genetic disorder that leads to abnormal blood vessel formation in the skin, mucous membranes, and often in organs such as the lungs, liver, and brain.

34
Q

What is an Angiofibroma?

A

Nasopharyngeal angiofibroma (also called juvenile nasopharyngeal angiofibroma) is a histologically benign but locally aggressive vascular tumor that grows in the back of the nasal cavity. It most commonly affects adolescent males.
