Introduction: The organisms that cause many device-related and other chronic infections actually grow in biofilms in or on these devices. We sought to examine the role of biofilm formation in chronic middle-ear ventilation tube infection.Case report: Scanning electron micrograph images are presented which demonstrate biofilm on a middle-ear ventilation tube removed from a five-year-old child's chronically discharging ear. A review of the relevant international literature explores the role of biofilms in chronic infection and discusses potential intervention strategies.Conclusion: Biofilms may be responsible for chronic middle-ear ventilation tube infection that resists treatment with conventional antibiotics.

Modified Radical Mastoidectomy

The original criteria for modifying a radical mastoidectomy were: (I) an intact pars tensa and a defective pars flaccid a with cholesteatoma; (2) normal or near normal hearing; and (3) an intact, functional ossicular chain. We propose a fourth criterion: that the cholesteatoma site be delineated lateral to the body of the incus. Control of the disease process is easily assured if the lesion is in that area. Our recommended fourth criterion is based on the results of a five-year study of fifty-two cases that met the original criteria. The cholesteatoma reoccurred in the middle ear in only one case. In six cases, periodic care is necessary because of retraction to the grafted attic area. The procedure and technique used in these patients and the excellent results are discussed in this article.
