Abstract

Introduction: Otitis media with effusion (OME) is an inflammation of the middle ear in which a collection of liquid is present in the middle-ear space while the tympanic membrane is intact. The association between adenoid inflammation and OME has long been noted but the exact mechanism is still much debated. We studied the role of adenoid mast cells in the causation of OME.

Objective: To study the distribution and role of adenoid mast cells in the causation of OME

Methodology: A cross-sectional, prospective study was carried out in the otorhinolaryngologic clinic, department of otorhinolaryngology (ORL), Science University of Malaysia, from June 1999 to September 2001. A total number of 50 cases were studied. Twenty-five of these patients underwent adenoidectomy, while another 25 patients underwent adenoidectomy and myringotomy with ventilation tube insertion. The adenoid specimens from all patients were examined for the number of adenoid mast cells present, using light microscopy and toluidine blue as the staining agent. The results were analysed using SPSS version 10.0 computer software.

Result: The population of adenoid mast cells in children with OME was significantly greater than that in children without OME (p = 0.000).

Conclusion: The increased number of adenoid mast cells in patients with OME suggests that inflammation may play a role in this condition.
