Abstract
Asthma, aspirin intorelance and nasal polyps form a triad of aspirin-induced asthma (AIA).
Thirty four cases of AIA, 10 males and 24 females, were seen at our clinic as of 1988. Asthma was found in 29 of 34 cases (85.3%), sinusitis in 22 of 32 cases (68.8%).
Nasal polyps were found in 25 of 34 cases (73.5%).
In the cases with polyps, asthma was aggravated by mouth breathing because of severe nasal obstruction. Thus, nasal polypectomy was useful for AIA with fellowing care;
1) Control of asthma was necessary before operation.
2) For local anesthesia, 2% Xylocaine was better, because 4% Xylocaine contained of Paraben and yellow dye.
3) Antrostomy or endonasal ethmoidectomy was useful, but non-steroidal anti-inflammatory drugs (NSAID) might be necessary for fever and/ or pain after operation. Therefore, we prefered simple polyectomy.
4) Steroid nasal spray was very effective for recurrence of nasal polyps.
