Transoral Robotic Surgery Versus Hypoglossal Nerve Stimulation for OSA: A Cost Analysis Study.

BACKGROUND

Transoral robotic surgery (TORS) lingual tonsillectomy and hypoglossal nerve stimulation (HGNS) are effective surgical interventions for well-selected patients with obstructive sleep apnea (OSA) intolerant to continuous positive airway pressure (CPAP) therapy. Previous publications have demonstrated that HGNS patients have a lower postoperative apnea-hypopnea index (AHI) and length of hospital stay than TORS patients. No prior study has investigated the differences in costs between HGNS and TORS.

OBJECTIVES

This study aims to compare surgery-related costs in patients undergoing HGNS versus TORS lingual tonsillectomy for OSA intolerant to CPAP.

METHODS

A retrospective study on OSA patients intolerant to CPAP that underwent HGNS or TORS from 2015 to 2022 at a tertiary care center. Cost was defined as the dollar amount associated with providing a specific service prior to the application of insurance.

RESULTS

This study included 395 patients (375 UAS and 20 TORS). Average total cost was significantly higher in the UAS group than the TORS group (UAS: $25,582.60; TORS: $5832.60; p < 0.001). Operating room costs were also significantly higher in the UAS group (UAS: $1978.20; TORS: $1490.90; p = 0.001). The TORS cohort averaged higher costs for pharmacy (UAS: $201.30; TORS: $416.60; p < 0.001) and anesthesia (UAS: $139.00; TORS: $307.60; p < 0.001).

DISCUSSION

The total cost was significantly higher in the UAS group compared to the TORS group. When making management decisions, it is important to consider the cost of care provided as well as patient-centered outcomes to optimize the value of care.
