    Journal: Am J Otolaryngol; 2020; 41(6):102742. PubMed ID: 32979662.
    Abstract:
    INTRODUCTION: Patients who do not tolerate continuous positive airway pressure (CPAP) for treatment of obstructive sleep apnea (OSA) often seek surgical management. A variety of procedures exist to address the nasal passages, oropharynx, hypopharynx, and larynx. Diagnostic studies including drug-induced sleep endoscopy (DISE) are helpful in identifying areas of obstruction. One potential site of obstruction is at the level of the epiglottis. We describe the use of robotic technology to assist with epiglottopexy to manage epiglottic retroflexion as a cause of two patients' OSA. This is the first reported robot-assisted epiglottopexy in the adult otolaryngology literature. METHODS: This is a case series of two patients with OSA who demonstrated epiglottis collapse into the airway during DISE. They were evaluated by polysomnographic testing (PSG), Epworth Sleepiness Scale (ESS), and physical exam. Given their epiglottic collapse seen on DISE, they underwent robot-assisted epiglottopexy. RESULTS: Both patients had moderate to severe OSA preoperatively. They successfully underwent robot-assisted epiglottopexy as a surgical intervention. They tolerated the procedure, and there have been no complications. Each reported improved symptoms, with patient one showing a decrease in total AHI and a substantial decrease in oxygen desaturations at night. The second patient reported a significant decrease in AHI and ESS. CONCLUSION: There are many options for surgical intervention in patients with OSA. Epiglottopexy is one method for addressing collapse of the epiglottis and can be achieved successfully through robot-assisted epiglottopexy in adult patients with OSA. LEVEL OF EVIDENCE: IV.
