Alternative and Non-PAP Therapy Concepts

1. Oral Appliances and Positional Therapy

Oral appliance therapy uses a custom-fitted mandibular advancement device (MAD) worn during sleep to hold the lower jaw (and tongue) forward, enlarging the upper-airway space. It suits mild-to-moderate obstructive sleep apnea or PAP-intolerant patients and is fitted by a qualified dental or medical provider — not the technologist. Positional therapy rests on positional sleep apnea — apnea substantially worse or present mainly when supine. Keeping the patient off their back (with positioning aids or a vibrating positional trainer that cues a position change) can meaningfully reduce apnea without a mask. Success depends on the apnea truly being position-dependent, demonstrated on monitoring.

2. Hypoglossal Nerve Stimulation and Surgery

Hypoglossal nerve stimulation (HGNS) — Inspire is the best-known device — is an implanted system that senses breathing and delivers timed stimulation to the hypoglossal nerve, causing the tongue to protrude and stiffen, opening the airway during inspiration. It has strict selection criteria (anatomy, body mass index, severity, collapse pattern) and is activated and managed under medical supervision. Upper-airway surgery changes anatomy: UPPP (uvulopalatopharyngoplasty) removes or repositions soft-palate and throat tissue; maxillomandibular advancement (MMA) moves the upper and lower jaws forward to enlarge the airway (a larger operation for severe or refractory cases). Tracheostomy is a surgical airway that bypasses the upper airway entirely — historically definitive for severe, life-threatening apnea; now rare and reserved for extreme cases. All surgical options involve operative risk and careful patient selection by the treating surgeon.

3. Referral, Selection, and Monitoring

Because each alternative has specific indications, limitations, and contraindications, they follow defined referral pathways: a sleep physician may refer to a dentist (oral appliance) or an otolaryngologist/sleep surgeon (HGNS, UPPP, MMA). Treatment selection by qualified providers uses the diagnostic study, anatomy, severity, preference, and contraindications. Patient preference and shared decision-making are central — the patient weighs benefits, burdens, and risks with their clinician. After any alternative is started, effectiveness monitoring (repeat testing or objective tracking of events and symptoms) confirms whether it is working, since success is variable and not guaranteed.

How it works

1. A diagnostic study establishes the apnea, its severity, and its position dependence and collapse pattern.
2. The physician discusses options with the patient — shared decision-making weighing PAP and each alternative's benefits, burdens, and risks.
3. The selected therapy is delivered through the proper referral pathway: a dentist fits a MAD, a surgeon performs HGNS/UPPP/MMA, or a positional device is issued.
4. The technologist supports effectiveness monitoring with follow-up testing and accurate event/position documentation.
5. Results are reviewed by the managing provider, who confirms effectiveness or adjusts the plan; the technologist documents and supports throughout.

Quick review

Topic Recap

Non-PAP alternatives solve the collapsible-airway problem by other means: oral appliance therapy (mandibular advancement devices) repositions the jaw; positional therapy — including vibrating positional trainers — keeps the patient off their back to treat positional sleep apnea; hypoglossal nerve stimulation (Inspire) electrically activates the tongue-protruding nerve; and upper-airway surgery (UPPP, maxillomandibular advancement) or, rarely, tracheostomy alters or bypasses the airway. All follow referral pathways to qualified providers, are chosen through shared decision-making with patient preference at the center, carry limitations and contraindications, and require effectiveness monitoring because success is not guaranteed. The technologist educates, documents, and monitors — never selects or prescribes.

Knowledge Check

1. Which device holds the lower jaw forward to enlarge the airway during sleep?
2. What must be true for positional therapy to be a realistic option?
3. How does hypoglossal nerve stimulation open the airway?
4. Name two upper-airway surgical procedures and their anatomical targets.
5. Who selects and prescribes a non-PAP therapy, and what is the technologist's role afterward?

Answers and Rationales

1. A mandibular advancement device (oral appliance). It advances the mandible and tongue to enlarge the upper-airway space.
2. The apnea must be positional — substantially worse or present mainly when supine. Keeping the patient off their back only helps position-dependent apnea.
3. It delivers timed electrical stimulation to the hypoglossal nerve, causing the tongue to protrude and stiffen during inspiration. Inspire is the best-known example.
4. UPPP, which removes/repositions soft-palate and throat tissue, and maxillomandibular advancement, which moves both jaws forward. Both widen/stabilize the airway surgically.
5. A qualified provider (physician/surgeon/dentist) selects and prescribes; the technologist educates, documents, and supports effectiveness monitoring. The technologist does not recommend or prescribe.
