OBJECTIVE: To determine the pattern of cellular infiltration in nasal polyposis among Malaysian population and to compare the pattern of cellular infiltration in nasal polyposis between Malaysian and other Asian countries.
MATERIAL AND METHOD: This is retrospective study done on patients diagnosed with nasal polyposis from January 2008 to June 2012 in University Malaya Medical Center. Only the patients undergoing first operation for nasal polyp and were confirmed polyp with histopathological sections were included in the study.
RESULT: A total of 80 subjects were included in the study. Of these 48.75% had neutrophil- predominant polyp which was in contrast with the eosinophil- predominant polyp of Caucasian population but similar to other studies done in Asian countries.
CONCLUSION: The etiology of nasal polyposis in Caucasians and Asians may be different and may need to be managed differently. It may be more appropriate to treat nasal polyposis in Asian population with long term antibiotics and more study needs to be done on this.
