Superior semicircular canal dehiscence (SSCD) syndrome refers to vestibulo-auditory dysfunction caused by a bony defect ('third window') in the otic capsule. There is an emerging subtype of SSCD with the dehiscence located medially, causing the superior semicircular canal to come into contact with the superior petrosal sinus (SPS)....
This is a single case report of a novel surgical technique for SSCD; no practice change is warranted until larger controlled studies confirm safety and efficacy.
If validated, venous sinus stenting could become a minimally invasive treatment alternative for SSCD patients who are not candidates for conventional surgery.
- 01Case report describes superior petrosal sinus stenting as a novel treatment for SSCD syndrome.
- 02SSCD is a vestibulo-auditory disorder caused by a gap in the bone overlying the superior semicircular canal.
- 03Stenting is minimally invasive compared to traditional SSCD surgical repair (craniotomy or transmastoid approach).
- 04Published in the Journal of NeuroInterventional Surgery (JNIS), a neuroradiology/interventional journal.
- 05Evidence is limited to a single case; broader applicability is unknown.
Superior petrosal sinus stenting is a feasible treatment approach for symptomatic SSCD syndrome.
