“…In a correlation study between the shape of type B tympanogram and the type of secretion there was a highly statistically significant positive correlation ( Table 2) which means that the more flatness of type B tympanogram the more the viscosity of the secretions. This is in agreement with Maw et al [16] who reported that when an effusion is present with a peaked tympanogram, it is more likely that the effusion will be serous, whereas with a flat tympanogram the majority of effusions are mucoid. It has been reported that the three parameters of tympanograms, pressure, compliance and gradient correlated with effusion within the middle ear [9].…”

Objective: To correlate the characteristics of type B tympanogram with the type of middle ear fluid in children suffering from persistent OME. Methodology:A prospective study was conducted on children with persistent OME for more than 3 months who failed to respond to medical treatment with type B tympanogram in one or both ears and were candidate for myringotomy. The middle ear fluid was aspirated and the viscosity of the fluid was evaluated objectively by measuring the diameter of the diffusion circle on a filter paper in mm.Results: Thirty eight children (70 ears) were enrolled in this study. The shape of type B tympanogram was either flat (67.14%) or peaked (32.86 %).Three fluid types were noticed in OME namely serous, mucoid and glue. The shape was highly correlated with the type of secretions. Compliance and gradient of type B tympanogram were negatively correlated with the viscosity of the secretions. Conclusion:Tympanometry is a beneficial clinical tool in prediction, diagnosis and management of OME. Characteristics of type B tympanogram were correlated with the viscosity of middle ear fluid. Detailed analysis of type B tympanogram can assist the clinicians in determining the indication of comprehensive treatment.

“…A previous study suggested that different effusions with various levels of enzymes and proteins were correlated with recurrent cases of OME (14). In contrast, Gibb and Mackenzie (7) and Maw et al (15) reported that there was no significant difference of the VT extrusion rate when the middle ear fluid was divided into liquid, glue and very thick glue.…”

ObjectivesThe objective of this study was to determine the various factors that affect the extrusion rate of ventilation tubes (VTs), including the nature of the middle ear effusion.MethodsA retrospective chart review of 82 pediatric patients (177 ears) who received VT insertion surgery under general anesthesia was carried out to evaluate the relationship between various factors and the VT extrusion rate. The factors we analyzed included age, gender, the adenoid size, the amount and content of the middle ear effusion after myringotomy, bleeding events, associated adenoidectomy and the findings of the tympanic membrane status, the tympanometry and the audiometry of the air bone gap.ResultsThe mean extrusion time was 254 days (range, 11 to 809 days). The patients with no history of previous VT insertion had a longer extrusion time (mean, 279 days) than did the patients who had undergone previous VT insertion (mean, 203 days). The patients with serous effusion had the shortest extrusion time (mean, 190 days) as compared to those patients with glue (273 days) and pus (295 days) effusions. Other factors had no statistical significant relationship with the extrusion time.ConclusionThe mean VT extrusion time was 254 days. The VT extrusion time was significantly related to the characteristics of the middle ear effusion and a history of previous VT insertion. Thus, the nature of middle ear effusion can provide a clinical clue to predict the VT extrusion time.

“…However, the results of previous studies on the relationship between middle-ear effusion characteristics and repetitive insertion of ventilation tubes showed conflicting results. Some reported that the characteristics of middle-ear effusion were not related to recurrence, 12,13 while others reported that mucoid discharge was associated with recurrence. 14 Therefore, the relationship between the nature of middle-ear effusion and recurrence needs to be confirmed in a larger, well-planned study.…”

ObjectiveTo determine the factors related to multiple ventilation tube insertions in children with otitis media with effusion.MethodsA retrospective review was performed of 126 ears of 81 children aged less than 12 years who had undergone insertion of a Paparella type 1 ventilation tube for the first time between August 2012 and March 2018.ResultsMean age at the first operation was 4.0 ± 2.2 years, and the mean duration of otitis media with effusion before the first ventilation tube insertion was 5.4 ± 4.5 months. Among 126 ears, 80 (63.5 per cent) had a single ventilation tube insertion and 46 (36.5 per cent) had multiple insertions. On multivariate logistic regression, tympanic membrane retraction, serous middle-ear discharge, and early recurrence of otitis media with effusion were independent predictive factors of multiple ventilation tube insertions.ConclusionTympanic membrane retraction, serous middle-ear discharge, and early recurrence of otitis media with effusion after the first tube extrusion are associated with multiple ventilation tube insertions.
