Brief Summary:
The purpose of this study is to assess if the da Vinci® Robotic Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA) allows for "adequate exposure" for transoral resection of hypertrophic lingual tonsils in patients with obstructive sleep apnea.
Detailed Description:
Visit 1 - Outpatient Clinical Setting. The patient will be evaluated prior to treatment in the outpatient clinical setting in a way which is consistent for routine workup prior to any surgery of the tongue base for sleep apnea. This will include sleep nasendoscopy (see below), and if it is predicted pre-treatment that the transoral robotic approach may be appropriate then the patient will be given the option of participating in the study. This will include a review of the patient's pre-operative sleep study and a nasopharyngolaryngoscopic exam to assess for lingual tonsillar hypertrophy. A pre-operative MRI will be obtained to provide quantitative measurement of the patient's tongue base hypertrophy.
Visit 2 - Sleep Nasendoscopy. The patient will undergo sleep nasendoscopy as outlined below, in order to assess the involvement of the tongue base in the patient's sleep disordered breathing. This is a routine diagnostic procedure. Patients are pharmacologically induced into a light phase of sleep and the upper airway is visualized directly with a nasopharyngolaryngoscope. Anesthetic management will be performed in standard fashion, using propofol titrated to an endpoint of moderate sedation, as is typically done for procedural sedation in esophagogastroduodenoscopy. Administration will be logged to permit analysis of dosing requirements. Respiratory pattern will be monitored noninvasively and logged to permit correlation of obstruction to propofol administration.
Visit 3 - Intraoperative Setting. The patient will undergo an evaluation for "adequate exposure" for transoral robotic surgery and if "adequate exposure" is achieved then they will undergo transoral robotic surgery for lingual tonsillar hypertrophy to treat obstructive sleep apnea.
Visit 4 - Postoperative Setting. This will be in the inpatient and/or outpatient setting within three weeks of surgical procedure. The patient will undergo routine postoperative clinical evaluation.
Visit 5 - Postoperative Testing. The patient will undergo a follow-up sleep study to determine efficacy of the surgical procedure at three months post-operatively, the standard interval used to determine the outcome of the procedure.
