Surgical treatment of epiglottis collapse in obstructive sleep apnoea syndrome: epiglottis stiffening operation

The epiglottis is an important structure that was largely ignored in early research on obstructive sleep apnoea/hypopnoca syndrome (OSAHS). Primary epiglottis collapse (EC) in patients with OSAHS is difficult to treat with conservative therapies, such as oral appliances and CPAP. Therefore, surgical treatment may represent a good option when dealing with EC, although up to now no standardised surgical procedures have been described. Herein, we describe a new surgical procedure that we called "epiglottis stiffening operation" (ESO); the technique is safe, devoid of complications, easy to perform and is effective in treatment of primary EC, which presents as a single or coexistent site of upper airway obstruction without altering fundamental functions of the epiglottis.
