Outcome Measures

Primary Outcomes (2)

  • Type 1 Polysomnography (PSG)

    Type I PSG measurements demonstrating Apnea Hypopnea Index (AHI) reduction.

    Pre-operative (within 12 months prior to surgery)

  • Type 1 Polysomnography (PSG)

    Type I PSG measurements demonstrating Apnea Hypopnea Index (AHI) reduction.

    90-150 days after surgery

    Intra-Operative Assessment

  • Robotic procedure time

    Intra-Operative Assessment

  • Estimated blood loss (EBL)

    Intra-Operative Assessment

  • Postoperative hemorrhage

    Intra-Operative Assessment

  • Blood transfusions

    Intra-Operative Assessment

  • +14 more secondary outcomes

Study Arms (1)

Single arm

Subjects will undergo TORS benign base of tongue resection procedures (i.e., partial glossectomy, epiglottoplasty, epiglottectomy, and/or lingual tonsillectomy) for the treatment of OSA

Device: Transoral Robotic Surgery

Interventions

Subjects will undergo TORS benign base of tongue resection procedures (i.e., partial glossectomy, epiglottoplasty, epiglottectomy, and/or lingual tonsillectomy) for the treatment of OSA. Concomitant non-robotic surgical procedures may also be performed as part of the subject's treatment for OSA, and can include one or more of the following: uvulopalatopharyngoplasty (UPPP), lateral pharyngoplasty, expansion sphincter pharyngoplasty, palatine tonsillectomy, or a modified uvulopalatoplasty. Nasal surgery such as septoplasty or turbinoplasty can be combined if it is needed.

Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

* Subject who has failed or is unable to tolerate CPAP therapy * Subject who is diagnosed with OSA due to redundant base of tongue tissue * Subject who has moderate to severe sleep apnea, defined as 15 or more AHI events/hour * Subject who has planned a tongue base resection surgery

You may qualify if:

  • Subject is between 18 and 80 years old
  • Subject with BMI ≤ 35
  • Subject with moderate to severe sleep apnea, defined as 15 or more AHI events/hour
  • Subject who has failed or is unable to tolerate CPAP therapy
  • Subject diagnosed with OSA due to redundant base of tongue tissue
  • Subject must be a suitable candidate for base of tongue resection surgery
  • Subject who is willing and able to provide written informed consent
  • Subject who is willing and able to comply with the study protocol requirements

You may not qualify if:

  • Subject with a poor mouth opening or trismus
  • Subject with evidence of any primary cancers or metastatic disease, other than skin cancers
  • Subject who has had a surgical resection and/or chemoradiation therapy for oropharyngeal cancer
  • Subject with congenital malformations in the larynx, throat or tongue
  • Subject with an American Society of Anesthesiologists (ASA) score of Grade 4 or above during preoperative evaluation
  • Subject for whom any additional surgeries are planned for OSA within the study period, after the surgery in which the da Vinci SP System was used
  • Subject who is mentally handicapped or with a psychological disorder or severe systemic illness, that would preclude compliance with study requirements or ability to provide informed consent
  • Subject is pregnant or suspected to be pregnant
