Insights
Tympanometric volume did not significantly predict surgical success in pediatric tympanoplasty (type I) for children aged 5-8 years. This study found no correlation between pre-operative tympanometric volume and graft uptake outcomes.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Audiology
Background:
- Chronic suppurative otitis media (CSOM) is a common condition in children.
- Tympanoplasty type I is a surgical procedure to repair the tympanic membrane.
- Predictive factors for successful pediatric tympanoplasty are crucial for optimizing outcomes.
Purpose of the Study:
- To investigate the prognostic significance of pre-operative tympanometric volume in pediatric tympanoplasty type I.
- To assess the correlation between tympanometric volume and graft uptake in children aged 5-8 years.
Main Methods:
- A prospective study of 30 children (5-8 years) with inactive mucosal CSOM undergoing tympanoplasty type I.
- Pre-operative tympanometric volume was measured and analyzed against post-operative graft uptake and audiological success (≥10 dB hearing improvement).
- Statistical analysis included Mantel Haenszel Chi-square and Fisher exact tests.
Main Results:
- The study achieved a surgical success rate of 87% and audiological improvement in 70% of cases.
- Patients were grouped by mean tympanometric volume (<1.6 cm³ vs. >1.6 cm³).
- Graft uptake was 95% in the lower volume group and 77% in the higher volume group, but this difference was not statistically significant.
Conclusions:
- Pre-operative tympanometric volume does not appear to be a significant prognostic factor for the surgical success of tympanoplasty type I in this pediatric age group.
- Further research may be needed to explore other potential predictive factors for pediatric tympanoplasty outcomes.
Objective:
To determine the prognostic significance of "Tympaometric Volume" for paediatric tympanoplasty type I in a select age-group of 5-8 years.
Methods:
A prospective study was conducted in 30 children with chronic suppurative otitis media-inactive mucosal disease of either sex. Pre-operative tympanometric volume was recorded in all the cases and statistically analysed with the graft uptake results post-operatively. All the patients underwent tympanoplasty type I by underlay technique using temporalis fascia graft. An intact graft at the end of 6 months, and a postoperative hearing improvement of 10 dB or greater in two consecutive frequencies, was regarded as surgical and audiological success, respectively. The statistical analysis was done using Mantel Haenszel χ(2) i.e. Chi square test, and Fisher exact p value test for confirmation.
Results:
We recorded an impressive surgical success rate of 87% and an audiological improvement of 70% in this study. On the basis of mean tympanometric volume of 1.6 cm(3) the patients were divided into two groups: in Group A (tympanometric volume<1.6 cm(3)), and group B (tympanometric volume>1.6 cm(3)). A graft uptake of 95% and 77% was recorded in Group A & B, respectively. However, the statistical evaluation of the data revealed no significant effect of this factor.
Conclusions:
In this study no correlation between the tympanometric volume and the surgical success of paediatric tympanoplasty in select age group of 5-8 years was observed.
