AI Article Synopsis
- Safe cochlear implantation (CI) can be performed successfully in patients with a canal wall down (CWD) mastoidectomy cavity, with no increased postoperative complications compared to standard procedures.
- A retrospective review of eight patients revealed that most were able to undergo single-stage implantation, with careful management of the external auditory canal and challenges related to ossification.
- Overall outcomes for patients indicated that CI is not only safe but also yields excellent auditory performance, similar to that of the general CI population with profound hearing loss.
Article Abstract
Background: Safe cochlear implantation (CI) is challenging in patients with a canal wall down (CWD) mastoidectomy cavity.
Objectives: We reviewed the outcomes of CI and proposed surgical management principles according to the presentation status of CWD mastoidectomy cavity.
Material And Methods: The cases of eight patients (nine ears) with CWD mastoidectomy cavity who underwent CI were retrospectively reviewed. The basis of the surgical decision, postoperative complications, and postimplant auditory performance were analysed.
Results: In seven patients (eight ears), implantation was performed in a single stage; in six ears, the external auditory canal (EAC) was oversewn. In two patients with ossification, the electrode array was inserted into the scala tympani by drilling of the basal turn or in the second turn of the cochlea through a drill-out procedure. Seven patients had a follow-up of 12-50 months and one patient was lost to follow-up. None of the followed-up seven patients suffered complications.
Conclusions: CI is safe and effective in patients with profound hearing loss after radical mastoidectomy. In patients with CWD mastoidectomy cavity, CI does not cause a higher rate of postoperative complications relative to standard CI procedures. The outcome is excellent and comparable to that in the general CI population.

To explore the effect of hydroxyapatite (HA) combined with concentrated growth factor (CGF) on the cavity filling during endoscopic mastoidectomy in patients with middle ear cholesteatoma. The data of patients with middle ear cholesteatoma who underwent endoscopic canal wall down (CWD) mastoidectomy and mastoid obliteration with hydroxyapatite in Huazhong University of Science and Technology Union Shenzhen Hospital from December 2017 to October 2023 were retrospectively analyzed. The patients were divided into observational group (HA+CGF) and control group (HA) according to whether CGF was used.

Article Synopsis
- This study evaluates the effectiveness of two staging systems (EAONO-JOS and Potsic) in predicting recurrence of cholesteatoma in children with different types (congenital, primary acquired, and secondary acquired).
- Conducted from 2015 to 2023, the research analyzed surgical outcomes from 31 ears in 30 pediatric patients, examining variables like residual disease and factors like stapes erosion that might signal recidivism.
- Results indicated high rates of residual disease, particularly in congenital and primary acquired cases, and found a potential correlation between certain variables and poorer outcomes; however, limitations in the staging systems decreased the predictivity for residual disease.

Mastoid obliteration can be performed after canal wall down (CWD) mastoidectomy with various materials. Homologous bone tissue harvested from cadaver donor represents a feasible option with advantages. The purpose of the study is to describe the case of a patient diagnosed with middle ear cholesteatoma treated with mastoidectomy of the CWD and mastoid obliteration with homologous freeze-dried corticocancellous bone particulate in the Cittadella Hospital Ear, Nose, Throat (ENT) unit.
