The Effect of Obstructive Sleep Apnea Operations on the Swallowing

Status Not yet recruiting

Clinical Trial Summary

The investigators hypothesize that partial robotic tongue base resection surgery and / or soft palate surgery, as a treatment for sleep apnea affect the swallowing quality.In order to characterize the dysphagia The investigators will locate participants undergoing this surgery more than six months ago.The investigators will test their swallowing by fiberoptic endoscopic evaluation of swallowing (FEES) and let participants fill out a questionnaire regarding swallowing disorders swallowing dysfunction questionnaire (SDQ). Also the investigators will use data collected from participants who have undergone this surgery and already had these tests due to swallowing complaints.

Clinical Trial Description

first step: The investigators will review the operating room reports, identify participants who underwent trans-oral robotic surgery for base of tongue and/ or soft palate surgery more than six months ago.

second step:

1. The investigators will locate and conclude data of participants who already underwent assessment of postoperative swallowing function (FEES test and SDQ).The investigators will review the summary of their meeting.

2. The investigators will Call participants who have not yet done swallowing assessment and invite them to a clinic appointment.

third step- participants come to the clinic. Receive an explanation, sign a consent form. Then the participants fulfill the SDQ questionnaire (patient self- filling questionnaire) in which the participants assess the quality swallowing.

Then the investigators will conduct the swallowing test - FEES test. During This test fiber optic fiber is inserted through the participants nose for the purpose of observing the pharyngeal and laryngeal areas.The participants eat and drink food and with different textures while looking for their swallowing mechanism via the optical fiber in order to identify swallowing problems.

forth step- Two laryngologists and a speech therapists will go over the recorded swallowing tests, filling out the two questionnaires:Swallowing performance status scale (SPSS) and Penetration- aspiration scale (PAS).

With these scales every participant receives a score that reflects the quality of swallowing. A higher score indicates a more severe swallowing disorder. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
