Tympanometeric changes following tonsillectomy and nasal packing

ABSTRACT

The effect of nasal packing and tonsillectomy on the middle ear pressure was investigated. Forty% of patients with bilateral anterior nasal packs had a negative pressure corresponding to type C1 and C2. However, the incidence of negative middle ear pressure with posterior packing was high [80%]. 53% of tonsillectomy patients developed negative middle ear pressure. No patients in this series developed middle ear effusion probably because the tubal dysfunction was partial and of short duration. Patients after tonsillectomy and nasal packing were advised to be examined otologically to exclude persistent negative middle ear pressure
