Pharyngeal Anatomy In Obstructive Sleep Apnea With HRM

Purpose

This is a single-arm study involving the use of a high resolution manometry (HRM) diagnostic device that is not utilized in any clinical decision-making processes. All patients scheduled for DISE as part of their regular clinical care will be screened for enrollment via described inclusion and exclusion criteria.

Condition

Obstructive Sleep Apnea

Eligibility

Eligible Ages: Over 18 Years
Eligible Genders: All
Accepts Healthy Volunteers: No

Inclusion Criteria

Adult patient (≥18 years old) - A diagnosis of obstructive sleep apnea as determined by polysomnogram with an apnea-hypopnea index of ≥ 5.0/hr - Intolerant of continuous positive airway pressure (CPAP) therapy due to physical or psychosocial limitations as determined by PI - Scheduled to undergo DISE as part of routine clinical assessment for further evaluation of pharyngeal anatomy

Exclusion Criteria

Patient is unable to consent for research due to a pre-existing neurologic condition as determined by PI - Patient is unable to consent for research due to language barriers - Patient has a history of egg allergy as determined by history or self- report - Patient is pregnant as determined by patient report or preoperative anesthesia evaluation - Cardiopulmonary or other medical conditions precluding safe sedation as determined by clinical history and exam - History of palatal or pharyngeal airway surgery except tonsillectomy as determined by clinical history and exam - History of radiation treatment to the head or neck as determined by clinical history and/or exam - Severe nasal airway obstruction preventing simultaneous flexible nasopharyngoscopy and manometry probe insertion as determined by physical exam

Study Design

Phase: N/A
Study Type: Interventional
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: All patients who meet eligiblity will undergo HRM at the same time as the operative DISE procedure.
Primary Purpose: Device Feasibility
Masking: None (Open Label)

Arm Groups

Arm	Description	Assigned Intervention
Experimental Investigational Device	Consented participants who meet eligibility will have a drug induced sleep endoscopy (DISE) with the Solar GI High Resolution pharyngeal Manometry system.	Device: High-resolution pharyngeal manometry catheter The system is a widely-used tool in gastrointestinal medicine for high resolution mapping of pressures within tubular organs.The device will be deployed trans-nasally into the pharyngeal and esophageal lumen in exactly the same fashion as is done for motility studies.

Detailed Description

High-resolution pharyngeal manometry (HRM) is a diagnostic technique that has the potential to objectively measure pharyngeal collapse patterns in obstructive sleep apnea (OSA) during sedation as well as natural sleep. The purpose of this study is to assess the utility of HRM in objectively mapping patterns of pharyngeal collapse observed during drug-induced sleep endoscopy (DISE). Quantifying pharyngeal collapse patterns that occur during sedation and in natural sleep may significantly impact the selection and success of surgical treatments, as well as surgical outcome assessment.
