Abstract
Otitis media with effusion (OME) is one of the most common diseases in young children. OME is defined as the presence of effusion (fluid) in the middle ear without any inflammation. This problem is considered as an infectious disease which is commonly seen in 2 to 4-year-old children and is less common after 6 years of age. It occurs more frequently in winter rather than spring or summer.
A bacterial organism is identified in approximately one third of middle ear effusions of children with OME who undergo myringotomy and the pathogens are primarily those that are found in the nasopharyngeal biofilms.
The aim of this study was to find the relation between nasopharyngeal bacteria in the Eustachian tube area and that in middle ear effusion in patients with otitis media with effusion (OME) that may provide insight into the pathogenesis and management of OME.
This study included 40 patients with OME (16 males and 24 females) with mean of age 6.475±5.906 years attending the otolaryngology department in Menufia University hospitals and Shiben El-Kom teaching hospital.
After having the patient consent all the patients underwent detailed history, full clinical examination especially ear examination, audiological assessment, radiological assessment, swab from nasopharynx at Eustachian tube area for bacteriological examination and sample from middle ear fluid for bacteriological examination.
Results of the current study show that 30 (75%) patients had history of recurrent attacks of AOM and 6 (15%) patients had family history of OME.
Summary
86
The complaint in the study group was bilateral hearing loss in 34 (85%) patient, delayed speech in 4 (10%) patients and unilateral hearing loss & tinnitus in 2 (5%) patients.
Otoscopic findings of OME were positive in 40 (100%) patients in left ear and only 38 (95%) patients were positive in right ear.
Thirty four (85%) of cases had positive findings in nasopharyngeal imaging and 6 (15%) patients had negative findings considering positive finding is that size of the adenoid is more than 50 % of the space of nasopharynx in lateral view X- ray.
Thirty eight (95%) patients had bilateral type B tympanogram and 2 (5%) patients had left type B and right type A tympanogram.
The most common bacteria cultured from swabs from tubal areas in nasopharynx were Haemophilus influenza (85% of patients) followed by Streptococcus pneumoiea (80-85% of patients) and Moraxella catarrhalis (20-25%of patients) with non-significant difference between righ and left tubal areas(P-value >0.05).
Culture results from ear samples were in 16 (40%) patients sterile . Different mixures of bacteria were found in24( 60 %) patients . The most common bacteria were Haemophilus influenza (25-35%)of patients and Streptococcus pneumoniea (35%)of patients followed by Moraxella catarrhalis (5-10%)of patients with non-significant difference between the two ears (P-value > 0.05).
There were highly significant relation between Rt ear sample and Nasopharyngeal swap in Rt tubal area in the study group P <0.01. Also there were highly significant relation between Lt ear sample and Nasopharyngeal swap in Lt tubal area in the study group P <0.01.
