July 2021mastoid, which could secondarily lead to a reduction in the volume of the epitympanic obliteration and a retraction of the cartilages. Moreover, this material must be carefully packed to avoid any cavities within the obliteration. The Glassbone was positioned from the anterior epitympanum to the aditus ad antrum, without bulging in the EAC to prevent any postoperative stenosis.
Reconstruction of the scutum was performed using cartilaginous and perichondrium grafts harvested from the tragus and covering the entire surface of the obliteration. The grafts were placed paying particular attention to the sealing between them to avoid any leakage of the Glassbone in the ear canal and to prevent any secondary retraction of the grafts. An ossiculoplasty was performed using a cartilaginous piece between the stapes and the TM. No intraoperative intravenous antibiotic therapy was given. The patient was sent home the day of surgery with a prescription of local antibiotics for 10 days. The study has been performed according to the Declaration of Helsinki (see supporting video).
The texture of the 45S5 Bioactive Glass was well suited for the epitympanic obliteration using a one-handed endo-scopic technique.
Results
No pre- or postoperative complications occurred. The texture of the 45S5 bioactive glass was well suited for the epitympanic obliteration using a one-handed endoscopic technique. The healing of the EAC was complete without leakage of the Glassbone. After one postoperative year, the patient had a self-cleaning intact ear canal, without stenosis (Figure 1b). The first diffusion-weighted imaging magnetic resonance imaging performed at one postoperative year was negative.
