What is Sleep-Disordered Breathing?

Sleep-Disordered Breathing (SDB) is a category of abnormal breathing conditions during sleep, including Obstructive Sleep Apnea (OSA), Central Sleep Apnea, and other hypoventilation phenomena. OSA is characterized by partial or complete upper airway obstruction during sleep, leading to apnea or shallow breathing, affecting sleep quality and causing various health problems.

The severity of sleep-disordered breathing is often underestimated, but the complications it can cause are quite extensive. Long-term untreated sleep-disordered breathing may lead to hypertension, cardiovascular disease, increased stroke risk, and metabolic problems such as diabetes. Additionally, daytime sleepiness, difficulty concentrating, and emotional problems are common, seriously affecting quality of life and work performance.

Obstructive Sleep Apnea (OSA) is the most common type. Major risk factors include obesity, large neck circumference, advancing age, male gender, and anatomical abnormalities such as enlarged tonsils or receding jaw.

Typical Symptoms Include:

Loud snoring

Breathing pauses

Frequent nighttime awakenings

Morning headaches

Dry mouth

Diagnosis typically requires polysomnography (PSG) or home sleep apnea testing.

Current Main Treatment Options:

Continuous Positive Airway Pressure (CPAP)

Provides continuous air pressure to physically open the upper airway; the gold standard therapy for moderate to severe OSA.

Oral Appliances (OA)

Primarily Mandibular Advancement Devices (MAD), which move the mandible and tongue base forward, expanding the posterior pharyngeal airway space. Suitable for mild to moderate OSA patients or those unable to tolerate CPAP.

Surgical Interventions

Including Adenotonsillectomy (A&T), particularly common for pediatric patients; other surgeries such as Uvulopalatopharyngoplasty (UPPP) aim to remove obstructive tissue or reshape airway structure.

Normal Breathing

The airway remains fully open during sleep, and breathing is smooth and quiet.

Primary Snoring

The airway becomes slightly narrowed. Soft tissues vibrate and produce snoring sounds, but breathing continues normally.

Upper Airway Resistance Syndrome (UARS)

The airway becomes noticeably narrowed. Breathing requires more effort, which disrupts sleep quality.

Mild OSA

The airway becomes intermittently obstructed, leading to brief episodes of breathing pauses or reduced airflow.

Moderate OSA

The airway collapses more frequently, causing drops in blood oxygen levels and fragmented sleep.

Severe OSA

The airway repeatedly collapses significantly, posing serious risks to cardiovascular health and overall well-being.

Increasing Severity

Orofacial Myofunctional Therapy (OMT) as an Important Adjunctive and Integrative Therapy

The mechanism of action is to strengthen the Upper Airway Dilator Muscles, such as the tongue muscles, tensor veli palatini, and pharyngeal constrictors. Clinical research confirms that OMT can:

Strengthens tongue and throat muscles Stabilizes the airway during sleep Serves as adjunct therapy for snoring and mild apnea Improves CPAP tolerance and comfort Enhances oral appliance therapy results Reduces relapse after airway surgery

Professional Responsibilities of Speech-Language Pathologists in OMT

According to the American Speech-Language-Hearing Association (ASHA) definitions and professional guidelines, Speech-Language Pathologists (SLPs) play an important role in OMT:

Slide 1

Conduct detailed structural and functional assessments, including orofacial muscle coordination, tongue position, mouth and nasal breathing patterns, and impact on swallowing and speech functions

Real Stories

"Initially I was just worried about my son's dental alignment, but after being referred by our dentist for orofacial myofunctional therapy, I discovered he had been mouth breathing all along. After receiving orofacial myofunctional therapy for a period of time, he gradually learned to breathe through his nose, his mouth naturally closed, and his bite improved significantly. Most happily, he sleeps better now, and even his teacher says his concentration has improved."

"I've actually had mild to moderate sleep apnea issues all along. It wasn't until my dentist fitted me with a sleep appliance and combined it with orofacial myofunctional training that my sleep improved tremendously. I wake up energized in the morning and don't fall asleep just sitting there anymore."

"I've been using CPAP for twenty years now. Honestly, the results have always been mediocre—sometimes the mask is uncomfortable, sometimes I wake up with dry mouth. Recently my doctor suggested I add orofacial myofunctional training. Initially I was skeptical, worried I couldn't do it. The therapist was very patient, teaching me to slowly practice breathing and tongue movements. At first it was really hard to get used to, but after persisting for a few months, I feel more energized in the morning. My family says I'm not as noisy when I sleep anymore. Thanks to the care of the treatment team."
