Plain English summary of protocol

Background and study aims
Obstructive sleep apnoea (OSA) is a condition where the walls of the throat relax and narrow or close during sleep. Myofunctional therapy (MT) is a recent treatment option for OSA that involves orofacial (mouth and face) muscle training. However, few OSA guidelines include myofunctional assessment routinely during the examination at the Ear, Nose & Thorat (ENT) office. This study aims to present the researchers' protocol for the examination of OSA adult patients, with a special interest in myofunctional evaluation.

Who can participate?
Patients aged 18 years and over who are scheduled for septoplasty (surgery to straighten the nasal septum) to screen for OSA

What does the study involve?
Once the routine ENT exam is done, the myofunctional exam includes measurements of lip sealing (how lips are closed during breathing), the lingual frenulum (tongue-tie that limits tongue movements), and the strength of the tongue and mouth muscles.

What are the possible benefits and risks of participating?
The main benefits for participants will be to receive an OSA diagnosis and myofunctional treatment. Few risks are expected, only related to a longer exam during the ENT consultation.

Where is the study run from?
Hospital Universitario de Fuenlabrada (Spain)

When is the study starting and how long is it expected to run for?
September 2021 to May 2025

Study objectivesMyofunctional therapy is a recent treatment option for obstructive sleep apnea (OSA). Examination of OSA adult patients should include myofunctional evaluation.
Ethics approval(s)

Approved 14/12/2021, Hospital Universitario de Fuenlabrada Ethics Committee (Camino del Molino, 2, Fuenlabrada, 28042, Spain; +34 (0)916006600; ceic.hflr@salud.madrid.org), ref: 21/65

Health condition(s) or problem(s) studiedObstructive sleep apnea (OSA)
InterventionENT office exam, polysomnography and myofunctional evaluation including breathing type, lip sealing, lingual frenulum and evaluation of muscle strength of the lingual and oral muscles with the IOPI.
Intervention typeOther
Primary outcome measurePolysomnography assessed with the Apnea-Hypopnea Index (AHI), with mild OSA defined as >5 events/h of sleep, moderate OSA as 15–29.9 events/h of sleep, and severe OSA as ≥30 events/h of sleep at one timepoint
Secondary outcome measuresThe following secondary outcome measures are assessed at one timepoint:
1. Anatomical findings in the upper airway from the nasal valve area to the larynx:
1.1. Friedman tonsil grading, scaled from 1 to 5
1.2. Height of the hard palate, measured in centimeters
1.3. Friedman tongue position (FTP), scaled from 1 to 5
1.4. Mallampati scales, scaled from 1 to 5
1.5. Basilingual hypertrophy assessed with lingual tonsil hypertrophy (LTH) Friedman classification, scaled from 1 to 5
1.6. Awake dynamic exam with Müller maneuver, considered collapsed or not
2. Myofunctional exam:
2.1. Breathing (nasal or oral)
2.2. Lingual sealing (opened or closed)
2.3. Lingual frenulum assessed using the Marchesani protocol (present or not)
2.4. Muscle strength evaluated with the Iowa Oral Performance Instrument (IOPI) in KiloPascals at buccinator and tongue propulsion
