We found the currently proposed classification more useful in that it follows the natural progression of the disease and is more practical in determining operative procedures at each stage.

Bile acids are present in a number of the ME samples of children with OME. Because of dilution, it is possible that more ears contain bile acids. Bile acids are known to be noxious to mucosal cells at a higher (pH) than pepsin and, therefore, might play a role in the pathology of OME.

The objective was to present our experience in the brochoscopic removal of foreign bodies in children. This was carried out through a retrospective analysis of the medical records of 96 patients in whom endoscopic removal of an inhaled foreign body was required, at the department of paediatric otorhinolaryngology, Eramus Medical Centre, Rotterdam. The participants were all children who underwent bronchoscopy after suspected foreign body aspiration from 1990 to 2000. The main outcome measures were confirmed diagnosis of foreign body aspiration and localization of aspirated foreign body. It was seen that in children up to 3 years of age, there was no significant difference in foreign body distribution and in children aged 3 and older foreign bodies were more commonly found in the right main bronchus. It was concluded that aspirated foreign bodies are equally distributed between the left and right main bronchus in children younger than 3 years. This could be explained by the handling of choking infants by their parents.

We conclude that packing after ear surgery may be safely abandoned. This would not only save valuable operating time, but would also obviate the need for pack removal, always a source of discomfort and anxiety. This is especially important in children, who may subsequently require a further general anaesthesia in order to remove the pack.

Protrusion differs significantly between sexes. This indicates that different criteria should be used to judge protrusion in boys and girls. None of our prominent ears exceeded only the demarcation in the lower protrusion, suggesting that upper protrusion plays a larger role in the perception of prominence than lower protrusion and should therefore be the main objective of corrective otoplasty. Furthermore, the variation of asymmetry of protrusion in the normal population indicates that an often used success criteria in otoplasty of an asymmetry less than 3 mm may be too strict.
