The effect of tonsillectomy and adenoidectomy on the intra-tympanic pressure
1Department of Otolaryngology, University of Turku, Finland.
Insights
Adenoidectomy and tonsillectomy significantly improved intratympanic pressure in children with recurrent ear infections or respiratory issues. Larger adenoids correlated with worse pre-operative pressure, indicating their impact.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Respiratory Medicine
Background:
- Recurrent otitis media and upper respiratory tract infections are common in children.
- Adenoidectomy and tonsillectomy are surgical interventions often considered for these conditions.
- Intratympanic pressure is a key indicator of middle ear status.
Purpose of the Study:
- To evaluate the effect of adenoidectomy and/or tonsillectomy on intratympanic pressure in children.
- To investigate the correlation between adenoid size and pre-operative intratympanic pressure.
- To assess the impact of tonsillectomy alone and nasal allergy on post-operative outcomes.
Main Methods:
- A cohort of 67 children (mean age 7 years) underwent adenoidectomy and/or tonsillectomy.
- Intratympanic pressure was measured pre-operatively and three months post-operatively.
- Adenoid size was assessed, and comparisons were made between children with large versus small adenoids.
Main Results:
- A highly significant improvement in intratympanic pressure was observed post-surgery (p < 0.001).
- Adenoid size showed a significant effect on pre-operative intratympanic pressure (p < 0.05), with larger adenoids associated with lower pressure.
- Tonsillectomy alone did not significantly alter intratympanic pressure, nor did nasal allergy impact post-adenoidectomy pressure.
Conclusions:
- Adenoidectomy and tonsillectomy are effective in improving intratympanic pressure in pediatric patients.
- Adenoid hypertrophy is a significant factor contributing to impaired middle ear pressure.
- Surgical intervention should consider adenoid size for optimal outcomes in managing pediatric ear and respiratory conditions.
Abstract:
A group of 67 children were studied (mean age 7 years, 2 months) who underwent adenoidectomy and/or tonsillectomy because of either recurrent otitis media or upper respiratory tract infection. The mean pre-operative intratympanic pressure was -67.3 mmH2O (SD 65.1); three months post-operatively it was -21.9 mmH2O (SD 32.4), a highly significant improvement (p less than 0.001). The size of the adenoids had a nearly significant effect on the pre-operative intratympanic pressure (p less than 0.05). In children with large vs small adenoids the difference was highly significant (p less than 0.001). In a group of five children, tonsillectomy alone (adenoidectomy performed earlier) did not have any effect on the intratympanic pressure. No change in intratympanic pressure was seen in children with nasal allergy as compared with non-allergic children after adenoidectomy.
