Postganglionic horner syndrome in three patients with coincident middle ear infection
1Private Practice, 980 Johnson Ferry Road, Suite 550, Atlanta, GA 30342, USA. fstop007@bellsouth.net
Abstract:
Three patients developed a postganglionic Horner syndrome during the course of an ipsilateral uncomplicated middle ear infection. The mechanism may be an effect on the middle ear caroticotympanic sympathetic plexus, for which there is considerable anatomic and physiologic evidence. Why Horner syndrome does not occur more often after middle ear infection is a mystery.
Insights
Middle ear infections can cause Horner syndrome, a neurological condition affecting the eye and face. This occurs via the sympathetic nerve plexus in the middle ear, though the exact reasons for its rarity remain unclear.
Area of Science:
- Neurology
- Ophthalmology
- Otolaryngology
Background:
- Horner syndrome is a clinical condition resulting from damage to the sympathetic nerves supplying the face and eye.
- Middle ear infections (otitis media) are common and typically treated with antibiotics.
- The sympathetic innervation of the head and neck involves complex pathways, including a plexus within the middle ear.
Observation:
- Three patients presented with postganglionic Horner syndrome.
- The Horner syndrome developed during an uncomplicated middle ear infection on the same side of the body (ipsilateral).
Findings:
- A potential mechanism for Horner syndrome in these cases is the involvement of the caroticotympanic sympathetic plexus located in the middle ear.
- Anatomical and physiological evidence supports the existence and function of this middle ear sympathetic plexus.
Implications:
- This study highlights a potential, albeit infrequent, neurological complication of middle ear infections.
- Further research is needed to understand why Horner syndrome is not a more common occurrence following middle ear infections.
- Understanding this association may improve diagnostic approaches for patients presenting with both conditions.
