ABSTRACT
OBJECTIVE:
To compare symptomatology in patients with unilateral versus bilateral superior semicircular canal dehiscence who underwent unilateral surgical repair. STUDYDESIGN:
Retrospective cohort study.SETTING:
Single surgeon series at tertiary academic medical center from 2002 to 2021.METHODS:
Patients were administered a standardized questionnaire regarding the presence or absence of 16 symptoms (11 auditory and 8 vestibular) pre- and postoperatively. Symptom rates were compared between patients with unilateral and bilateral dehiscence, and paired statistical testing was used to analyze symptom improvement with surgery.RESULTS:
Our final cohort included 125 patients, 93 (74%) with unilateral superior canal dehiscence syndrome (SCDS) and 32 (26%) with bilateral SCDS. Bilateral patients had an increased burden of auditory and vestibular symptoms compared to unilateral patients before surgery (7.6 vs 6.2, P = .03) and after surgery (3.1 vs 1.9, P = .02). Both groups experienced a significant reduction of symptoms following repair (P < .01 for both).CONCLUSION:
Our study has 2 keyfindings:
First, patients with bilateral dehiscence seem to be more symptomatic, reporting more auditory and vestibular symptoms both before and after surgery. Second, bilateral patients still seem to benefit from unilateral repair, demonstrating a significant reduction in the number of symptoms with surgery. Our findings may help inform the management of the sizable proportion of SCDS patients with bilateral defects.
