Superior Semicircular Canal Dehiscence (SSCD) is a rare inner ear condition that leads to vestibular and auditory symptoms. It occurs due to the absence or thinning of the bony part of the labyrinth that overlies the superior semicircular canal.

Managing SSCD:
By addressing the root cause of SSCD, patients can significantly improve their quality of life and alleviate the distressing symptoms associated with this condition.
SSCD stands for Superior Semicircular Canal Dehiscence. It is a condition where a thin or absent section of bone over the superior semicircular canal creates an abnormal third window in the inner ear. This opening can disrupt pressure balance, causing sound- or pressure-induced vertigo, oscillating vision, and hearing sensitivity to internal body sounds.
In the context of the National Clinical Classification (NCC), SSCD still expands to Superior Semicircular Canal Dehiscence. The abbreviation and meaning do not change under NCC terminology. It remains a recognized vestibular disorder involving a bony defect that alters inner ear fluid mechanics and pressure transmission.
Within NCC terminology, SD SW expands to Semicircular Dehiscence, Superior Canal. This is a classification label used to describe a bony defect at the superior semicircular canal site. It aligns with clinical naming conventions but is formatted to meet NCC’s structured coding hierarchy for inner ear and vestibular pathologies.
SSCD refers to a bony opening over the superior semicircular canal in the inner ear. This defect creates abnormal pressure sensitivity, allowing sound or physical strain to stimulate balance signals inappropriately. People may notice dizziness from loud noise, ear fullness, echoing, pulsatile sensations, or hearing internal sounds like eye or joint movement.
Yes, SSCD can be serious if symptoms interfere with daily life or go undiagnosed. It may lead to chronic imbalance, noise-triggered vertigo, reduced quality of life, and hearing distortion. While not always dangerous, persistent pressure sensitivity warrants specialist evaluation to prevent symptom progression and support safe, effective management.
