Plastic Surgery

Background:

Stenosis of the cartilaginous auditory canal presents a significant surgical challenge.
Various plastic surgery techniques have been proposed for its treatment.
The authors previously developed a technique for tracheostomy stenosis.

Purpose of the Study:

To adapt and evaluate a modified surgical technique for treating stenosis of the external auditory canal and concha.
To assess the efficacy and safety of day-surgery conchomeatoplasty under local anesthesia for auditory canal stenosis.

Main Methods:

A modified technique, initially used for tracheostomy stenosis, was applied to the external auditory canal and concha.
Fourteen patients with cartilaginous auditory canal stenosis underwent the procedure under local anesthesia.

Pre- and post-operative measurements of the auditory canal diameter at the narrowest point were recorded.

Main Results:

The conchomeatoplasty procedure was performed as day surgery under local anesthesia.
Post-operative auditory canal surface area ranged from 113 mm² to 254 mm², indicating successful widening.
Good results were observed eight months after surgery, with flaps demonstrating adequate blood supply and survival.

Conclusions:

The proposed conchomeatoplasty technique is a simple, effective, and minimally invasive method for correcting external auditory canal stenosis.
The procedure can be safely performed under local anesthesia with good patient outcomes.
The technique's success is supported by the good blood supply to the ear structures, ensuring flap viability.
