Male, 54-year-old Oropharyngeal stenosis Dysphagia • dyspnoea — — Otolaryngology Unusual or unexpected effect of treatment Transoral robotic surgery (TORS) is an effective and safe option for obstructive sleep apnea syndrome (OSAS) patients with isolated retrolingual obstruction, as well as part of multilevel surgical approach in case of multi-level obstruction. Stenosis after TORS in OSAS patients is rarely described and no literature review has inves-tigated this dramatic untoward event. We report on a case of severe recalcitrant oropharyngeal stenosis after multilevel surgery with transoral robotic tongue base resection in an OSAS patient, leading to tracheotomy and gastrostomy dependence. Following the failure of numerous conservative therapeutic attempts, oropharyngeal patency was restored after extensive scar tissue removal through an open-neck approach, followed by a pharyngeal reconstruction with radial forearm free flap (RFFF). Recalcitrant oropharyngeal stenosis is a dramatic complication that must be considered in OSAS patients sub-mitted to TORS in a multilevel strategy and that is rarely described in the literature. A thorough review of the existing literature is presented to assess which factors are involved and the therapeutic strategies invoked in this scenario. The adoption of resection tools suited for robot-assisted surgery and the staging of TORS in case of multilevel surgery could decrease the risk of extensive scar formation. To date there is still no broad con-sensus on which therapeutic choice is the best for recalcitrant oropharyngeal stenosis. When minimally inva-sive treatments fail, a wide scar resection with a RFFF oropharyngeal reconstruction could be considered as a valuable option to restore the upper aerodigestive tract patency.
