Nasal polyps are benign, pedunculated swellings of nasal mucosa usually associated with allergic rhinitis or chronic sinusitis. Nasal polyp can be single or multiple depending upon the aetiology. The lining becomes increasingly swollen and then hangs down. Single polyps are usually caused by sinus infection or in rare causes nasal tumours.
Common symptoms are nasal congestion, rhinorrhoea, postnasal drip, snoring, insomnia, reduction with sense of smell and headaches. Nasal polyps can impair a person’s quality of life. Obstruction of the sinus opening frequently leads to recurrent sinusitis.
Oral corticosteroids are the most effective medical treatment for nasal polyps but the effect is usually temporary. Nasal steroid sprays can reduce the growth of small polyps and are more effective in the postoperative period to prevent regrowth of polyps.
The standard surgical treatment is endoscopic removal of nasal polyps under direct vision with preservation of maximum amount of normal nasal mucosa. After surgical removal, future recurrence of polyp formation is still possible. In expert hands the risk of neurological or orbital complications are very rare.
