The transmastoid approach clearly reduces the invasiveness but does not provide a direct view of the SSCD.
Two ways of treating SSCD have also been described in the literature, including plugging and resurfacing the canal defect.
The population included patients who were hospitalized in the Department of Otolaryngology Head and Neck Surgery between November 2009 and October 2012, with a diagnosis of SSCD confirmed by HRCT.
Once the location of the dehiscence was identified using a Buckingham mirror, a dumpling structure [Figure 1] was placed on the SSCD to repair the dehiscence, formed by autologous bone powders filling in the middle of the temporalis fascia.
05, normal distribution and equal variance, t -test) of patients with unilateral SSCD.
Most of the patients showed complete resolution (4/10) or partial resolution (5/10), except for 1 patient with aggravated bilateral SSCD (patient No.
Therefore, the transmastoid approach was proven to be effective and safe for patients with SSCD.
All of the patients with unilateral SSCD (7/10) had satisfactory outcomes because all or most of the symptoms disappeared after surgery.
The VEMP threshold in the affected ear was lower than that in the normal ear in either all of the patients or those with unilateral SSCD based on statistics, which were in accordance with those from previous studies.
The management of SSCD syndrome involves conservative and surgical approaches.
A thorough review of the English-language literature suggests that this is the first report of bilateral SSCD associated with bilateral large internal auditory meatus.
SSCDs can cause (1) a significant reduction in sound-induced round-window velocity at low frequencies, (2) small but significant increases in sound-induced stapes and umbo velocities, and (3) a measurable fluid velocity inside the dehiscence.
