“…This fact presumably leads other experienced endoscopic surgeons to adopt the microscope for this surgical step implying the superiority of the two-handed technique (no tears, no bleeding). 29 The skin over the intracanalicularly placed electrodes did not fail to allow contamination and failure of the device, but the visibility of the electrode (6 cases) 28 potentially spread to the device during an episode of external otitis. Moreover, nobody could guarantee that the electrode will not move during or after the obliteration of the EAC trough, which theoretically could affect the device performance.…”

“…27 in order to gauge the FN course, and then, they drill a blind intramastoid channel close and parallel to the EAC wall, which will join the limited medial trough. 29,48 The trough area that needs obliteration is minimised while the preserved remaining EAC wall guides, immobilises and protects most of the electrode. Despite these modifications, no study in this review presented functional postoperative results (except one case of failed CI of unknown cause 28 ).…”

“…Despite these modifications, no study in this review presented functional postoperative results (except one case of failed CI of unknown cause 28 ). The average length of follow-up in cases without a mastoidectomy [27][28][29]48 ranged from 7.3 to 16 months so no safe conclusions can be drawn for the integrity of the EAC trough and thus the electrode.…”

Cochlear implants can achieve hearing rehabilitation in individuals with severe and profound sensorineural hearing loss (SNHL) who have little benefit from hearing aids. 1 The conventional microscopic technique was first described in 1976 by House. 2 This traditional approach requires a transmastoid posterior tympanotomy (PT) under a microscopic view. Electrode insertion is achieved either through the round window (RW) or through a bony cochleostomy. 3 Although the success of this approach is undeniable, alternative surgical approaches have been proposed to avoid mastoidectomy complications and minimise the invasive nature of the surgery. [4][5][6] Additionally, PT does not always guarantee satisfactory exposure of the round window niche (RWN) through the facial recess (FR) due

“…However, due to the advantages of the standard MPTA, the use of endoscope in CI became mainly limited to help the surgeons in accurate identification of the RW membrane and precise electrode placement; also this technique appears to be particularly useful for malformed or abnormal cochlea [39][40][41].…”

Advances in Rehabilitation of Hearing Loss

Cochlear implantation (CI) is usually performed under general anesthesia using the classic surgical approach, the mastoidectomy posterior tympanotomy approach (MPTA), which was originally described by William House in 1961. Many alternative surgical approaches have been described for CI. Robotic image-guided cochlear implantation has also been described as a new advance in CI. Also, in some situations, CI can be performed under conscious sedation with local anesthesia (CS-LA) instead of general anesthesia (GA). With the ongoing advance in CI devices and surgical techniques, CI surgery nowadays could preserve hearing in ears with preoperative residual hearing. This chapter describes different approaches and techniques in CI surgery, whether classic or alternative technique, with special attention to advantages and disadvantages of each approach or technique. Also this chapter describes, in surgical points of view, the anesthetic techniques in CI, whether GA or CS-LA, with focus on indications, advantages, and disadvantages of CS-LA in CI.

“…It is known that about 1.6% of otosclerosis subjects will progressively develop profound hearing loss, due to the sensorineural hearing loss (SNHL) component, induced by ossification of the round window membrane and/or cochlear scalae [Castillo et al, 2014;Kabbara et al, 2015], which should be distinguished from SNHL due to other causes [Shea et al, 1999]. In 60% of patients with advanced otosclerosis, ossification of the round window membrane is seen [Marchioni et al, 2016].…”

A Role for Acoustic Stimulation in Advanced Otosclerosis: Direct Acoustic Cochlear Implant versus Cochlear Implant

et al. 2018

Recent findings support the efficacy of the direct acoustic cochlear implant (DACI) in patients with advanced otosclerosis whose rehabilitation is very challenging. Standard treatment consists of stapes surgery combined with hearing aids or a cochlear implant (CI). CI surgery, however, is often challenging depending on the grade of otosclerosis. This study aims to compare speech perception scores in quiet and noise of 6 DACI and 12 CI patients with advanced otosclerosis at 3 and 12 months after fitting. Preoperative computed tomographic scans of all patients were scored by experts using an existing otosclerosis grading system (stages 1–3). Speech perception in quiet was significantly better for DACI compared to CI users at 3 months after fitting. At 12 months, no difference was found between DACI and CI patients. Speech perception scores in noise were significantly better in the DACI group. In summary, a DACI system seems to provide an effective treatment option as the acoustic component can be preserved in patients with advanced otosclerosis.
