More Than Meets the Ear: Incidental Cerebrospinal Fluid Leak During Myringotomy in a Child With Common Cavity Deformity

Cerebrospinal fluid (CSF) otorrhea represents a breach of the temporal bone separating the subarachnoid space from the middle ear and carries a significant risk of meningitis. While most cases are associated with trauma or prior skull base surgery, congenital fistulas may remain occult until unmasked by otologic procedures....

Audiologists and ENT teams managing children with common cavity deformity (a rare inner-ear malformation) should be aware that myringotomy carries a risk of CSF leak and meningitis; pre-operative imaging review and surgical planning should reflect this risk, but this is a single case and does not change standard audiology practice independently.

This case underscores the importance of careful pre-surgical evaluation in children with inner-ear malformations, where an apparently routine procedure can expose a potentially life-threatening complication.

1. 01Incidental CSF (brain fluid) leak occurred during myringotomy (eardrum surgery) in a child with common cavity deformity.
2. 02Common cavity deformity is a rare congenital inner-ear malformation with abnormal cochlear-vestibular anatomy.
3. 03CSF otorrhea (brain fluid draining through the ear) carries a significant risk of bacterial meningitis.
4. 04Published in Cureus as a case report (PMID 42634643); evidence level is very low.
5. 05Case highlights the need for pre-operative imaging and multidisciplinary planning in children with known ear malformations.
