Summary
This study shows that adjustable tongue advancement surgery is a feasible and safe option for reducing apnea-hypopnea index (AHI) and snoring in patients with obstructive sleep apnea (OSA) who cannot tolerate CPAP.
Area of Science:
- Otolaryngology
- Sleep Medicine
- Surgical Innovation
Background:
- Obstructive sleep apnea (OSA) is a serious condition often treated with CPAP.
- Patients intolerant to CPAP require alternative treatments for hypopharyngeal collapse.
- Current hypopharyngeal surgeries have limitations in efficacy and morbidity.
Purpose of the Study:
- To evaluate the feasibility, safety, and efficacy of a novel tongue advancement procedure.
- To assess the impact of the procedure on apnea-hypopnea index (AHI) and snoring.
- To provide an alternative surgical option for OSA patients with CPAP intolerance.
Main Methods:
- A prospective, nonrandomized, multicenter study included 10 patients with moderate to severe OSA and CPAP intolerance.
- A novel tongue advancement procedure involving a tissue anchor and adjustment spool was performed.
- Patients were followed for 6 months to assess outcomes.
Main Results:
- The mean AHI significantly decreased from 22.8 to 11.8 (p = 0.007).
- Snoring scores decreased significantly from 7.5 to 3.9 (p = 0.005).
- Four technical and one clinical adverse event were reported.
Conclusions:
- Adjustable tongue advancement is a feasible and relatively safe treatment for selected OSA patients.
- The procedure effectively reduces AHI and snoring in CPAP-intolerant individuals.
- Ongoing refinements aim to further improve the tongue advancement technique.

01:21Sleep Apnea
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

01:22Cardiopulmonary Resuscitation II: ACLS Airway Management
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
01:25Suctioning the Oropharyngeal Airway
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
