Introduction: The operative remediation of recurrent and chronical paranasal sinus diseases is received standard whenever a nonsurgical therapy has no or non-permanent improvement. How high is the risk that blood from the operative region attains to the tympanic cavity via eustachian tube?
Methods: We measured the tympanometric pressure and the static compliance preoperatively and the first day postoperatively of patients who underwent a paranasal sinus surgery. We surveyed the eardrums via otological endoscope and took additionally a photo.
Results: We could find a discrete, unilateral, tympanic haemorrhage in 2 cases after examination of 34 patients. The corresponding tympanogram showed always tubal dysfunction. The tubal dysfunction was detected totally in 12 cases.
The tubal function improved for 8 patients. The tympanometric pressure was identical to the preoperative results for all the others patients.
Conclusion: The prevalence of tympanic haemorrhage after microscopic paranasal sinus surgery is rare. A tubal dysfunction on the other hand can be detected frequently.
