“…This approach has been shown to be safe, effective and less invasive than the middle cranial fossa approach; it can be performed as a day-case operation. [35][36][37][38] There have also been a few reports of using a transcanal approach to round window occlusion, particularly to treat hyperacusis. [39][40][41] This remains an experimental form of management of this syndrome.…”

“…Theses included the following: audiometry (10, 12, 13, 15, 17–25), vestibular-evoked myogenic potentials (VEMPs) (18, 19, 21, 22, 25), head impulse test (HIT) (14, 26), video head impulse test (vHIT) (26), caloric tests (25), and presence of induced nystagmus (17, 25). Audiometry comprised the air conduction (AC) pure-tone average (PTA), the BC PTA, the air bone gap (ABG) closure, and in some cases the SRT or the Word Recognition Score (WRS).…”

Heterogeneity in Reported Outcome Measures after Surgery in Superior Canal Dehiscence Syndrome—A Systematic Literature Review

et al. 2017

View full text Add to dashboard Cite

BackgroundSuperior canal dehiscence syndrome (SCDS) can be treated surgically in patients with incapacitating symptoms. However, the ideal treatment has not been determined.ObjectivesThis systematic literature review aims to assess available evidence on the comparative effectiveness and risks of different surgical treatments regarding: (1) symptom improvement; (2) objectively measurable auditory and vestibular function; (3) adverse effects, and (4) length of hospitalization.Search method and data sourcesA systematic database search according to PRISMA statement was conducted on Pubmed, Embase, and Cochrane library. In addition, reference lists were searched. No correspondence with the authors was established. The last search was conducted on June 9, 2017.Study eligibility criteriaRetrospective and prospective cohort studies were held applicable under the condition that they investigated the association between a surgical treatment method and the relief of vestibular and/or auditory symptoms. Only studies including quantitative assessment of the pre- to postoperative success rate of a surgical treatment method were included. Case reports, reviews, meta-analysis, and studies not published in English, Dutch, or German were excluded.Data collection and analysisThe first author searched literature and extracted data; the first and last analyzed the data.Main resultsSeventeen studies (354 participants, 367 dehiscences) met the eligibility criteria and were grouped according to surgical approach. Seven combinations of surgical approaches and methods for addressing the dehiscence were identified: plugging, resurfacing, or a combination of both through the middle fossa (middle fossa approach); plugging, resurfacing, or a combination of both through the mastoid (transmastoid approach); round window reinforcement through the ear canal (transcanal approach). Several studies showed high internal validity, but quality was often downgraded due to study design (1). Outcome measures and timing of postsurgical assessment varied among studies, making it unfeasible to pool data to perform a meta-analysis.ConclusionA standardized protocol including outcome measures and timeframes is needed to compare the effectiveness and safety SCDS treatments. It should include symptom severity assessments and changes in vestibular and auditory function before and after treatment.

“…This involves delineation of the superior canal through a transmastoid approach and identification and plugging of the canal proximal and distal to the dehiscence. There have been 4 subsequent reports of transmastoid plugging of the superior canal; one has reported 5 well-documented cases of combined plugging and resurfacing in which plugging was the primary surgical act (4), and the second is a report of a single case managed with plugging under local anesthesia. The patient did well after a severe but transient postoperative sensorineural hearing loss (7).…”

Transmastoid craniotomy repair of the superior semicircular canal dehiscence using a soft tissue graft offers numerous advantages over traditional surgical approaches and can be performed safely in the outpatient setting. The strategy is particularly useful in patients with dehiscence at the superior petrosal sinus. This article will review our strategy and discuss the advantages and disadvantages of the different surgical treatments used for patients with severe symptoms from superior canal dehiscence.

A Dehiscent Superior Semicircular Canal May Be Plugged and Resurfaced Via the Transmastoid Route

Abstract: A superior semicircular canal dehiscence may be plugged and resurfaced via the transmastoid approach, thus avoiding the more invasive middle fossa craniotomy.
