What Causes Infections in the Inner Ear?

Diseases of the inner ear can produce symptoms such as hearing loss, dizziness, and tinnitus. There are many reasons, such as infections, trauma, tumors, drugs, etc. Sometimes the reasons are unknown.

Because the facial nerve passes through the ear, ear disorders may affect it. For example, shingles in the ear can affect the facial nerve and the auditory nerve, causing facial nerve edema, which is compressed as it passes through the cranial foramen, and can cause temporary pressure after the facial nerve is compressed. Or permanent facial paralysis.

The facial nerve bends away from the brain multiple times and travels in the temporal bone. All external ear, middle ear and inner ear infections, tumors and trauma and surgery can cause facial paralysis, which accounts for 90% of peripheral facial paralysis. There are several aspects of facial paralysis that are closely related to ear disorders in clinical practice. 1. Acute and chronic otitis media with facial paralysis: Facial palsy caused by acute otitis media is mostly caused by congenital facial nerve osteotomy of children, suppurative inflammation, and congestion and edema of nerves. Facial paralysis can be recovered quickly if antibiotic treatment or tympanostomy drainage is performed in time. Chronic otitis media is caused by osteomyelitis destruction and cholesteatoma compression, which damages the bone canal and exposes the facial nerve. It is caused by partial or complete necrosis and disconnection. The lesion should be removed and nerve repair or transplantation surgery should be performed.

2. Traumatic facial paralysis due to ear surgery:

(1) Cholesteroma and osteomyelitis damage the facial nerve bone canal, facial nerve inflammation and necrosis, and granulosis, which are mistakenly considered as inflammatory granulation and scraped, especially those with horizontal fistula in the semicircular canal, which are often accompanied by facial nerve damage. Special care is required when scraping granulation, and it is best to operate under the supervision of a neuromonitor. Attachment of the external ear canal and microtia should also be noted when performing tympanoplasty.

(2) In the case of tympanoplasty, mastoidectomy, and sacrum surgery, especially for microtia deformity and ear canal atresia, it is not advisable to scrape easily when encountering abnormal cord structure, raised bone-like structure and granulation in the facial nerve pathway In addition, the facial nerve tissue must be removed before treatment, otherwise it is easy to cause facial paralysis.

(3) During the operation of ear diseases, the surgeon is also very likely to damage the facial nerve and cause peripheral facial paralysis due to unfamiliar anatomy, insufficient experience, and careless operation.
