Highlights
•
Subtotal petrosectomy is a technique useful in some special situations for cochlear implant surgery
•
Few cases have been reported in the literature regarding this technique
•
We present three clinical cases performed at a high complexity hospital in the city of Bogotá, Colombia, which underwent a cochlear implant surgery with subtotal petrosectomy without mastoid obliteration
•
These cases, added to other reports, can offer valuable information about the long-term benefits and complications of SP.
Abstract
Objectives
To report and analyze three cases of subtotal petrosectomy (SP) in cochlear implant surgery at our institution, and establish the indications, surgical technique and complications encountered.
Materials and method
A retrospective descriptive study is proposed, analyzing a series of three clinical cases of subtotal petrosectomy as surgical technique for cochlear implant surgery at San Ignacio University Hospital (Bogotá, Colombia) from year 2004 to 2019.
Results
A total of three cases of subtotal petrosectomy as surgical technique in cochlear implant candidates were analyzed. The indications were the presence of a wide mastoid cavity after canal wall down mastoidectomy, extrusion of the electrode into the external auditory canal with a wide mastoid cavity and erosion of the posterior wall of the ear canal, and the presence of cholesteatoma in a cophotic ear with previous surgery.
The ear canal was defunctionalized in all three cases; in two of them with obliteration of the Eustachian tube and in none of the cases the mastoid was obliterated. There was a single complication associated with the procedure corresponding to a small retention cholesteatoma in the skin of the obliterated duct sac, that didn't required surgical intervention.
Conclusion
Subtotal petrosectomy is a surgical alternative for cochlear implant surgery in patients with chronic ear pathology, wide cavities or cochlear implant extrusion, not associated to significant complications.
