Perilymph fistulas caused by myringotomy
Abstract:
Two cases of rupture of the round window membrane verified by operation are presented. Both cases arose in connection with myringotomy and were presumably caused by a violent force acting directly on the tympanic membrane and the ossicles. This would result in a strong movement of the stapes and an acute change in the perilymph pressure, thereby causing an indirect injury to the round window. Symptoms and treatment are briefly discussed.
Insights
Round window membrane ruptures can occur after myringotomy due to forceful impacts on the eardrum, causing indirect injury. Surgical verification confirmed these cases, highlighting potential complications of the procedure.
Area of Science:
- Otolaryngology
- Neurosurgery
- Auditory Medicine
Background:
- The round window membrane is a delicate structure in the inner ear crucial for hearing.
- Myringotomy, a surgical procedure involving an incision in the tympanic membrane, is common for treating middle ear conditions.
- Indirect trauma to the round window membrane is a potential, though rare, complication.
