Internal laryngocele is a rare lesion of the larynx that expands medially to the thyroid hyoid membrane, distinguishing it from combined variants that extend both medially and laterally. Managing internal laryngocele requires a precise surgical approach matched to its endolaryngeal anatomy.
This protocol addresses the specific subtype of internal laryngocele — a rare laryngeal lesion classified by its direction of expansion. Unlike combined laryngoceles, internal laryngoceles are confined medially, which directly informs the preferred surgical route and technique.
Management centres on an endoscopic surgical technique delivered through the laryngeal lumen, using laser-based resection as the primary modality. This approach is considered the gold-standard method for internal laryngoceles.

These rare lesions of the larynx can be classified as internal or combined.
Internal laryngoceles expand medially to the thyroid hyoid membrane, while combined laryngoceles are positioned both medial and lateral to the membrane.
Internal laryngoceles are routinely managed by an endolaryngeal CO2 laser approach, though cold steel and combined pen surgical approaches have also been utilized.
Resection with a CO2 laser is the preferred technique, because it is precise, efficient, and safe compared with an open approach.
However, microlaryngoscopy currently remains the gold standard for the management of internal laryngoceles.
