[Complications of transtympanic eustacian tube insufflation (author's transl)]
Abstract:
Serous otitis media is sometimes treated by Eustacian tube catheterization or by insufflation of the middle ear via a myringotomy. Both techniques can cause death as has been described in the literature. Two patients, in whom following middle ear insufflation via a myringotomy air was found intracranially are presented. In one the finding on skull X-ray was coincidental and no symptoms occurred, whereas in the other a paresis of the right foot that lasted for 30 min occurred from the time of the middle ear insufflation for his serous otitis media.
Insights
Middle ear insufflation for serous otitis media can lead to air entering the skull. While one patient had no symptoms, another experienced temporary foot weakness, highlighting potential neurological risks.
Area of Science:
- Otolaryngology
- Neurology
- Medical Procedures
Background:
- Serous otitis media (SOM) is a common middle ear condition.
- Treatments for SOM include Eustachian tube catheterization and middle ear insufflation via myringotomy.
- These procedures carry known, albeit rare, risks, including mortality.
Observation:
- Two cases of intracranial air following middle ear insufflation are presented.
- The air was identified after the insufflation procedure.
- This complication occurred in patients undergoing treatment for SOM.
Findings:
- In one patient, intracranial air was an incidental finding on skull X-ray with no associated symptoms.
- The second patient developed transient right foot paresis lasting 30 minutes post-procedure.
- This suggests a potential link between middle ear insufflation and neurological events.
Implications:
- Middle ear insufflation, while a treatment for SOM, carries a risk of intracranial air embolism.
- Neurological complications, such as temporary paresis, can occur.
- Clinicians should be aware of these risks and consider alternative treatments or careful monitoring.
