What Researchers Did
Researchers conducted a retrospective analysis of 29 cases of inner ear decompression sickness (IEDCS) in 24 recreational divers over a 12-year period.
What They Found
Inner ear decompression sickness (IEDCS) accounted for 26% of severe decompression sickness cases, with 79% of injuries attributed to decompression schedule violations. Symptoms appeared within one hour of ascent in 83% of cases; 52% of divers experienced combined vestibulo-cochlear injury, but only 28% with vestibular injury and 32% with cochlear damage achieved full recovery.
What This Means for Canadian Patients
Canadian recreational divers should strictly adhere to decompression schedules to minimize the risk of inner ear decompression sickness, which often leads to incomplete recovery. Prompt recognition of symptoms like dizziness or hearing changes after diving is crucial, as early treatment may improve outcomes, though full recovery is not guaranteed.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a retrospective case series, this study is limited by its design, potential for selection bias, and the relatively small sample size.
