No Effect of a Nasal Decongestant on Eustachian Tube Function in Children With Ventilation Tubes,

THE LARYNGOSCOPE, Issue 6 2002
Niels van Heerbeek MD
Abstract Objective The aim of the study was to assess the effect of a topical decongestant on eustachian tube function in children with ventilation tubes because of persistent otitis media with effusion. Study Design A randomized, double-blinded, placebo-controlled study. Methods At the outpatient departments of a secondary referral hospital and a tertiary referral hospital, eustachian tube function was measured before and after intranasal administration of five drops of 0.05% xylometazoline hydrochloride or placebo in 80 randomly selected children with ventilation tubes because of otitis media with effusion. Results Xylometazoline nose drops had no effect on the ventilatory or the protective function of the eustachian tube. Conclusions Topical decongestants do not have a positive effect on eustachian tube function in children. Therefore, the use of topical decongestants to prevent or treat otitis media with effusion in children is not justified and should be discouraged. [source]

The Relationship Between Dental Overbite and Eustachian Tube Dysfunction,

THE LARYNGOSCOPE, Issue 2 2001
James P. McDonnell DMD
Abstract Objective The purpose of this study was to investigate the association between deep dental overbite and eustachian tube dysfunction (ETD). Design Case-control study Setting Tertiary care pediatric otolaryngology outpatient clinic at the Children's Hospital, Boston, Massachusetts. Patients 105 patients between the ages of 2 and 6 years. Study Measurements Dental overbite, overjet, and occlusal relationships were measured by an observer who was unaware of ETD status. ETD was defined as having ventilation tubes in place or having the recommendation for ventilation tube placement by an attending pediatric otolaryngologist. In addition, demographic information and medical and social histories were prospectively recorded. Results In a multivariate logistic regression model, children with deep bites were 2.8 times more likely to have ETD than those without deep bites (P = .03). Other independent risk factors for ETD identified in this model were family history of otitis media (OM) and age less than 3 years. Conclusions Children with deep dental overbites are at a significantly increased risk for developing ETD. [source]

Saline Irrigation in the Prevention of Otorrhea After Tympanostomy Tube Placement,

THE LARYNGOSCOPE, Issue 2 2000
Rick D. Gross MD
Abstract Objectives: Comparison of intraoperative saline irrigation to otic drops in the prevention of postoperative otorrhea in children with middle ear effusion undergoing bilateral myringotomy with ventilation tubes. Study Design: This study was designed as a blinded, controlled, prospectively randomized trial. Methods: Study children were randomly assigned to receive either otic drops for 3 days postoperatively or saline irrigation of the middle ear space at the time of myringotomy. Only children with effusion present at the time of surgery were included. All children were evaluated for drainage 7 to 14 days postoperatively, and the degree of drainage was graded from 0 to 4. Results: Of the 84 patients entered into the study, 62 patients were eligible for data analysis (16 failed follow-up, 6 records were lost). Of the patients who completed the study, not all had bilateral effusions, resulting in 111 ears for inclusion in the study. Fifty-two ears underwent irrigation, and 10 were noted to have otorrhea (19.2%). Fifty-nine ears received otic drops, resulting in 21 ears with otorrhea (35.6%). Evaluating the degree of otorrhea with a five-point Leichert scale, the average score per ear was 0.42 for the saline irrigation group and 1.07 for the control group. The rate and degree of drainage were both statistically reduced in the saline irrigation group (P < .05). Conclusions: Using middle ear irrigation at the time of tympanostomy may be more effective than antibiotic drops in preventing postoperative otorrhea. [source]

Matrix metalloproteinases 2 and 9 in otitis media with effusion

CLINICAL OTOLARYNGOLOGY, Issue 6 2001
C.R. Jennings
Matrix metalloproteinases 2 and 9 in otitis media with effusion A qualitative and quantitative study of the presence of matrix metalloproteinase 2 (MMP 2) and matrix metalloproteinase 9 (MMP 9), in the effusions of otitis media with effusion (OME), was performed. The activity of the above enzymes was compared in thick and thin effusions, and concentrations compared in samples from children with one, two, three and four sets of ventilation tubes. The activity of both MMP 2 and MMP 9 was higher in thick than thin effusions, P = 0.07 and P = 0.04, respectively. The concentrations of MMP 9 did not vary with the number of tube insertions but those of MMP 2 did (ANOVA P < 0.05). MMPs may be involved in tympanic membrane damage and prognosis of OME. [source]
