Surgery by Dr. Miguel Arístegui
En SurgSchool, the most innovative and dynamic mobile app in the medical world, incorporates a new surgery of the Dr. Miguel Arístegui, a reference in otology and ear surgery, which shows step by step the placement of a Sentio active transcutaneous bone conduction implant in a patient with bilateral atresia of the external auditory canal.
Clinical context and implant selection
The patient, aged 46, presented with a bilateral congenital atresia and had previously used external bone conduction devices. However, he was looking for a definitive, aesthetic solution without skin complications, so he opted for a Sentio active transcutaneous implant, thus avoiding the problems associated with traditional percutaneous systems.
The felt It stands out for its active transmission technology through the bone, without the need for a pin that goes through the skin, offering a Greater biocompatibility, lower infection rates, and better hearing comfort.
Surgical technique
El Dr. Arístegui make a carefully planned incision in the mastoid region, avoiding that it rests on the magnet or the vibrating transducer to prevent mechanical interference.
After infiltration and dissection, a muscle and subcutaneous flap which will accommodate the implant and the anchoring magnet, creating a well vascularized and protected pocket.
By means of controlled milling of the mastoid bone—in an area of reduced pneumatization—the bone bed is adapted to receive the transducer. The transducer is then placed Sentio implant and is fixed precisely, ensuring adequate vibration transmission to the temporal bone.
La reconstruction by plans It is performed with absorbable suture, taking care of the muscular coverage over the device and guaranteeing an optimal aesthetic result.
Advantages of the Sentio system
El Sentio implant represents the significant evolution in bone conduction systems, offering:
- Active vibration transmission directly to the bone without percutaneous elements.
- Lower risk of skin complications and without the need for external maintenance.
- Greater mechanical stability and sound quality, even in poorly pneumatized bones.
- Superior aesthetic results, being completely covered under the skin.
This technology allows hearing to be restored effectively in patients with atresia of the external auditory canal, microtia or other congenital malformations of the middle ear.
Educational importance
The video is available at SurgSchool provides detailed surgical vision of the entire procedure, from incision planning to device insertion and fixation.
Dr. Arístegui emphasizes key aspects such as the choice of surgical plane, adaptation of the bone bed and protection of the vibratory system, fundamental elements to achieve an optimal functional and aesthetic result.
