OSA Paper Podcast
by Ryan Nord, MD
Every day, one new paper on obstructive sleep apnea surgery: hypoglossal nerve stimulation, palate surgery including barbed reposition pharyngoplasty, tongue base, skeletal and nasal procedures, patient selection and comparators. Every episode summarizes the paper, walks through it as a teaching round, places it against a 440-paper evidence library, and ends with whether it should change practice.Episodes are written and narrated by an AI system working from the full text of each paper and the host's curated library of digests, under rules set by the host. They are reviewed for teaching, not for patient care. Nothing here is medical advice.Episode guide and subscribe links: https://www.sleepapneaimplant.org/podcastProduced by Ryan Nord, MD (VCU Health). Disclosures: consultant to AvivoMed; previously a consultant to Inspire Medical Systems (ended 2025) and Medtronic. No company funds or reviews this podcast.
Episodes
-
Adenotonsillectomy for Children With Mild Sleep-Disordered Breathing - Who Benefits?
The take-home point is this. For a snoring child with enlarged tonsils, a near-normal sleep study need not, by itself, talk a family out of adenotonsillectomy. Bring the headline into the counseling room. About two in three children were meaningfully better a year after early surgery. With…

Phrenic Nerve Stimulation Enhances Upper Airway Patency During Drug-Induced Sleep Endoscopy in Obstructive Sleep Apnea
The take-home point is about counseling and teaching, not candidacy. Here is the headline one last time. A single phrenic burst at the end of expiration gave nearly two-thirds more inspiratory flow, sixty-four percent, in thirteen sedated patients. It doesn't alter who is offered surgery today....
-
Effect of Novel Hypoglossal Stimulation on Airflow and Airway Collapsibility in OSA
The take-home point. A needle-placed electrode next to the distal hypoglossal nerve turned the airflow back on, almost to CPAP level, in sedated patients. Peak flow reached zero point four one liters per second with stimulation, against zero point four three on CPAP. That held in thirteen of...
-
Physiologic Mechanisms of Response to Hypoglossal Nerve Stimulation
The take-home point: this paper strengthens the case for asking what stimulation does to the airway, not just what it does to the tongue. The decision it touches is the Inspire workup, at both ends. DISE is a good tool both in the Inspire candidacy workup and for the non-responder once awake...
-
Association Between Body Mass Index and Unilateral Hypoglossal Nerve Stimulation Efficacy Depends on the Pattern of Pharyngeal Collapse in Obstructive Sleep Apnea
The take-home point: read body mass index through the DISE pattern, not on its own. One more time, the number to remember. In lateral-wall patients, every five extra points of body mass index went with about twenty points less A-H-I reduction. In anteroposterior patients, it was about four…
more -
Anthropometric Measurements Inform Complete Concentric Collapse Status in Patients With Obstructive Sleep Apnea
The take-home point: DISE stays in the Inspire candidacy workup, and this paper gives better numbers for counseling. Dr. Nord and Heiser were the two blinded reviewers who scored the DISE videos for this study. Remember the headline. The tree's negative predictive value was ninety-six in a…
more -
Deep Learning-Based Automatic Scoring of Drug-Induced Sleep Endoscopy in Obstructive Sleep Apnea
The take-home point starts with where DISE sits. In Dr. Nord's practice, DISE is part of the Inspire candidacy workup. It's also a good tool for the Inspire non-responder once awake endoscopy and reprogramming have failed. The decision this paper touches is how that video gets read. For Inspire...
-
Subjective and objective measures of sleep-related function from the Cardiovascular Endpoints For Obstructive Sleep Apnea with Twelfth Cranial Nerve Stimulation (CARDIOSA-12) trial: Sleep-related functional outcomes in CARDIOSA-12
Here's the take-home point. Patients felt better on full stimulation, but they didn't test faster. The Epworth fell about one and three-quarter points more than on partial therapy, and the reaction-time tests showed no statistically significant change. Dr. Nord's practice is a high-volume Inspire...
-
Three-Year Outcomes of Proximal Hypoglossal Nerve Stimulation in OSA
The take-home point is simple. With proximal stimulation, the median A-H-I was roughly halved, from about thirty-six to about nineteen, and it stayed there for three years. That is real durability evidence for a different device. Dr. Nord has previously consulted for Inspire. For an Inspire...
-
Hypoglossal Nerve Stimulation and Hypoxic Burden in Patients With Obstructive Sleep Apnea: A Secondary Analysis of the STAR Trial
The take-home point is two facts side by side. In large cohorts, hypoxic burden predicted cardiovascular death and major cardiovascular events when the AHI did not. And on Inspire therapy, about seven in ten patients in this STAR analysis, seventy-seven of one hundred and eight, had their burden...
-
Proximal Hypoglossal Nerve Stimulation for Obstructive Sleep Apnea in the OSPREY Study: A Randomized Controlled Trial
Here is the take-home point. Nearly six in ten treated patients met the response bar at seven months, against roughly one in seven with the device switched off. That is a real, randomized effect, for an investigational proximal device made by LivaNova. For a high-volume Inspire implanter, as in…
more -
A Randomized Trial of Nefopam for Postoperative Pain Management in Obstructive Sleep Apnea Patients Undergoing Uvulopalatopharyngoplasty
The take-home point. Nefopam did not lower morphine after UPPP. On the first day, patients used a median of seven milligrams with nefopam and five with placebo, both remarkably little. On top of a strong scheduled regimen, the extra drug bought nothing this trial could detect. The decision this...
-
Systematic Review on the Safety of Outpatient Upper Airway Surgery for Obstructive Sleep Apnea Patients in Ambulatory Surgical Centers
The take-home point. In Dr. Nord's practice, airway-surgery patients like the ones in this review are kept for twenty-three-hour observation, and that includes B-R-P. The decision this paper touches is whether B-R-P patients could move to same-day discharge from a surgery center. This review does...
-
Association Between Perioperative Celecoxib, Acetaminophen, and Opioid Consumption After Palate Surgery for Obstructive Sleep Apnea
The take-home point: this paper gives an adult, sleep-apnea-specific signal that scheduled celecoxib goes with modestly less opioid use on the first day, and it sharpens how patients are counseled. Here is why it fits. Dr. Nord performs barbed reposition pharyngoplasty, and airway-surgery…
more -
Predictive Factors for Surgical Outcomes and Symptom Persistence After Uvulopalatopharyngoplasty in Patients With Obstructive Sleep Apnea
The take-home point is about selection and counseling for palate surgery. In Dr. Nord's practice that operation is BRP, and this paper is not BRP. It used no barbs, it pooled adjunct procedures in unreported numbers, and it never assessed collapse pattern with DISE. So its odds ratios do not...
-
Uvularis Muscle Strengthening Advancement in Palatopharyngeal Collapse in Selected Cases of Snoring and Obstructive Sleep Apnea: A Randomized Trial
The take-home point: this paper adds a counseling option for a narrow group of patients, and a snoring hypothesis worth testing. It doesn't change who is offered Inspire or B-R-P. First, the headline once more. The uvularis stitch did not significantly lower the A-H-I. Palatoplasty alone finished...
-
Uvulopalatopharyngoplasty Versus Expansion Sphincter Pharyngoplasty - A Single Centre Experience
Here is the take-home point. Dr. Nord performs barbed reposition pharyngoplasty and teaches residents in the operating room and clinic. The decision this paper touches is which palate operation to choose when DISE shows lateral wall or concentric collapse at the velum, and how to counsel that...
-
Auditory Perceptions Associated With Hypoglossal Nerve Stimulation for Obstructive Sleep Apnea
The take-home point: this paper changes the counseling conversation and the follow-up questions. It doesn't change who is offered Inspire or how the implant is placed. Dr. Nord is a high-volume Inspire implanter, so in Dr. Nord's practice the first decision this touches is consent. Tell…
more -
Preservation Palatopharyngoplasty for Obstructive Sleep Apnea: Predictors and Clinical Outcomes
Here is the take-home point. The decision this paper touches is what to offer a patient with moderate to severe sleep apnea who is not a good Inspire candidate. Often that is because of large tonsils, a high body mass index, or both. Dr. Nord's practice implants Inspire at high volume and…
more -
Post-Operative Radiological Evaluation of a Bilateral Hypoglossal Nerve Stimulation System
The take-home point is simple. For a patient with a Genio implant, the plain film is the image that shows the hardware. Every x-ray was clean, all eleven. Every CT carried artifact, all eight. Dr. Nord's practice is built on high-volume Inspire implantation and barbed reposition pharyngoplasty....
-
Exploring the Role of Drug-Induced Sleep Endoscopy in Optimizing Upper Airway Stimulation Therapy for Non-Responders
The take-home point: Dr. Nord considers DISE with the stimulator on a good tool for the Inspire non-responder who tolerates the device, once awake endoscopy and reprogramming have failed. Copper's group gives a clear way to run it: settings first, then add-on therapy targeted to whatever stays...
-
GLP-1 receptor agonists for obstructive sleep apnea: a meta-analysis of randomized controlled trials
The take-home point: this paper sharpens how Dr. Nord's practice counsels patients about weight and surgery, even though it doesn't change who is offered surgery. The decision it touches is the conversation with a patient who carries excess weight and is considering Inspire or barbed reposition...
-
Edema and Subjective Discomfort After Barbed Stayed Bridge Pharyngoplasty (BSBP)
The take-home point: pain about three out of ten on day one and near zero by one month is a promising early-recovery signal. But it describes one technique, in thirty selected patients, under one fixed protocol. The first decision it touches is technique choice. In Dr. Nord's practice, B-R-P...
-
Hypoxic Burden Reduction After Lateral Pharyngoplasty in Patients With Obstructive Sleep Apnea - Beyond the Apnea-Hypopnea Index
The take-home point: this paper doesn't alter who is offered palate surgery or Inspire. What it adds is a fuller way to describe results and to counsel patients afterward. Keep the headline in mind. Whole-night hypoxic burden fell to about a third of baseline. The median went from ninety-seven...
-
Ultrasonographic Tongue Base Motion Does Not Correlate With Hypoglossal Nerve Stimulation Outcomes
The call for Dr. Nord's practice is no change, with a watch on ultrasound as a research tool. The decision this paper touches is what to make of tongue motion after implantation. Three pieces. First, counseling. I won't tell a patient that a strong forward tongue at activation predicts a great...
-
Oropharyngeal Lateral Wall Collapse on Drug-Induced Sleep Endoscopy as a Predictor of Hypoglossal Nerve Stimulation Response in Obstructive Sleep Apnoea-A Systematic Review
So, what does this systematic review mean for our clinical practice? In terms of an explicit call: watch. There is no change to our implant candidacy gate, but we must maintain a close watch on emerging trials of concurrent pharyngeal reconstruction. Let us break down the exact decisions affected...
-
Consensus Statements Among European Sleep Surgery Experts on Tongue, Hypopharynx, and Supraglottis Associated With Snoring and Obstructive Sleep Apnea - Part 1 - Evaluation and Decision Making
What is the bottom line for my clinical practice? My explicit call on this paper is watch, accompanied by immediate operational reinforcement of our existing surgical protocols. This paper does not require an immediate change in operative technique because it represents expert consensus on...
