Every day, one new paper on obstructive sleep apnea surgery, read in full and placed against a library of more than four hundred papers: hypoglossal nerve stimulation, palate surgery including barbed reposition pharyngoplasty (BRP), tongue base, skeletal and nasal procedures, patient selection and comparators. Each episode runs about fifteen minutes in four parts: the paper in two minutes, a teaching round, where it sits in the literature, and whether it should change practice.

Chumpathong and colleagues at Siriraj Hospital in Bangkok ran a small randomized, placebo-controlled trial asking whether nefopam, a non-opioid pain drug not approved in the United States, reduces morphine use in the first day after uvulopalatopharyngoplasty for obstructive sleep apnea. Added to a strong multimodal pain regimen, it did not: both groups needed only a few milligrams of morphine, with no statistically significant difference. Because the trial was underpowered, it supports not adding nefopam routinely while leaving a modest effect unexcluded.
Asghar M, Pang K, Asghar M, Rotenberg B. Head & Neck Surgery = le Journal D'oto-rhino-laryngologie et de Chir 2025
A 2025 systematic review from Rotenberg's group asked whether adults with obstructive sleep apnea can safely have nasal and palate surgery in ambulatory surgical centers and go home the same day. Across mostly older, hospital-based studies, unplanned admission for medical reasons averaged 5.4 percent across the four studies that reported it, above the authors' own 3 percent benchmark, and serious events were rare and came within the first few hours. The take-home point: the review maps early risk usefully but contains almost no true surgery-center data, so it does not yet justify moving pharyngoplasty patients out of overnight observation.

A single-surgeon retrospective study by Badash and colleagues, with Kezirian as senior author, asked whether celecoxib or acetaminophen given around palate surgery for obstructive sleep apnea was associated with less opioid use in the first day after surgery. Higher celecoxib doses were associated with modestly lower opioid use, while acetaminophen showed no significant association, and 205 of 210 patients still received opioids. Because celecoxib became routine partway through the study period, the finding is one to watch for confirmation in a randomized trial.

A single-center study from Wujin Hospital in China asked which preoperative features predict success after a modified uvulopalatopharyngoplasty for obstructive sleep apnea. About two in three patients met the success definition at short-term follow-up, and a lower Friedman stage, lower body mass index and higher lowest oxygen saturation were linked to success. The proposed prediction model has not been validated outside the patients who built it, so it is one to watch.

A randomized trial from Zagazig University in Egypt asked whether adding a uvularis muscle advancement stitch to modified anterior palatoplasty improves outcomes in young adults with mild or early moderate obstructive sleep apnea and single-level, front-to-back palatal collapse. In 34 patients, the added stitch did not significantly lower the apnea-hypopnea index compared with palatoplasty alone, although bed-partner-rated snoring improved more. The snoring benefit is one to watch, pending a blinded, registered trial.
A retrospective single-center study from the Medical University of Innsbruck compared expansion sphincter pharyngoplasty with a muscle-sparing uvulopalatopharyngoplasty in patients with snoring or obstructive sleep apnea, with the operation chosen by drug-induced sedation endoscopy findings. Expansion sphincter pharyngoplasty significantly lowered the apnea-hypopnea index, to about 13 events per hour, while the uvulopalatopharyngoplasty group's fall was not significant; expansion sphincter pharyngoplasty also brought more minor bleeding and more strong pain medication. The study adds independent support for palate operations that reshape the lateral pharyngeal wall and gives frank morbidity numbers for counseling, but it cannot prove superiority and does not test barbed reposition pharyngoplasty.

Researchers at Virginia Commonwealth University surveyed Inspire hypoglossal nerve stimulation recipients by telephone to ask whether they hear new sounds when the device stimulates. About one in six reported a new buzzing or humming sound during stimulation, mostly mild, and none had stopped using the device; preexisting tinnitus was not a statistically significant predictor in this small sample. The finding changes how patients are counseled and questioned about sound at follow-up, not who is offered the implant.

A single-surgeon retrospective series from the Medical University of South Carolina asked how adults with moderate to severe obstructive sleep apnea fare after preservation palatopharyngoplasty, and which baseline features predict a larger drop in the apnea-hypopnea index. The apnea-hypopnea index was cut roughly in half, with larger tonsils and higher baseline severity predicting bigger drops, though only a minority of patients were cured. The take-home point: the paper sharpens counseling for patients with large tonsils who fall outside Inspire candidacy, but it needs controlled, longer-term confirmation.

A single-center German case series of eleven patients asked what the first postoperative image should be after implanting the Genio bilateral hypoglossal nerve stimulator. Plain x-rays showed the hardware cleanly in every patient, while every computed tomography scan carried metal artifact, and the paper reported no clinical outcomes linking paddle position to function. The take-home point: plain films make a sensible day-one baseline, and repeat imaging over time is needed to show whether the paddles migrate.
Copper's group at Sint Antonius Hospital in the Netherlands described how they use drug-induced sleep endoscopy with the stimulator switched on in patients who still fail Inspire hypoglossal nerve stimulation after standard titration, and what happened to those patients afterwards. In a small retrospective series without a control group, patients who had settings changes or added therapy and returned for follow-up saw their apnea-hypopnea index fall by about 18 events per hour. Dr. Nord considers the procedure a good tool for the tolerant non-responder once awake endoscopy and reprogramming have failed, while noting that the series cannot show the endoscopy itself caused the improvement.

A meta-analysis in Sleep and Breathing pooled randomized trials of liraglutide and tirzepatide in adults with moderate-to-severe obstructive sleep apnea. The drugs lowered the apnea-hypopnea index by about ten events per hour more than control, but the effect depended heavily on the drug, and pooled oxygen measures did not improve significantly. The paper does not change who is offered surgery, but it sharpens counseling: quote drug-specific numbers, re-test after weight loss, and, as in Dr. Nord's practice, treat weight-loss drugs and Inspire as complementary parts of treatment, though no trial has yet tested them together.

Researchers at Sapienza University of Rome followed a small, carefully selected group of patients with moderate obstructive sleep apnea after barbed stayed bridge pharyngoplasty, a muscle-sparing barbed palate operation, to measure early pain, swelling and discomfort. Pain stayed low, averaging about three out of ten on the first day and near zero by one month, with no bleeding, but without a comparison group the study cannot show the technique outperforms barbed reposition pharyngoplasty. Dr. Nord's take-home point: a promising early-recovery signal for one technique in thirty selected patients, still awaiting a head-to-head comparison with barbed reposition pharyngoplasty.
A single-center study from the Pontifical Catholic University of Campinas in Brazil asked whether lateral pharyngoplasty lowers hypoxic burden, a measure of nighttime oxygen loss, and not just the apnea-hypopnea index. In the 27 patients with hypoxic burden measured before and after surgery, median hypoxic burden fell to about a third of baseline. It also fell significantly in patients who failed by apnea-hypopnea index criteria, but the study had no control group and measured no cardiovascular outcomes. Verdict: watch — it supports reporting hypoxic burden alongside the apnea-hypopnea index after palate surgery, without changing who is offered surgery.

A two-center Swiss study asked whether the way the tongue base moves on awake ultrasound during hypoglossal nerve stimulation predicts how much a patient's obstructive sleep apnea improves. In 64 patients with unilateral Inspire implants, no ultrasound measure of tongue movement size, symmetry or shape was significantly associated with the drop in the apnea-hypopnea index, though the confidence intervals were wide. The call is no change in practice, with ultrasound worth watching as a research tool.
A systematic review of eight Inspire cohorts, 1,051 patients in all, asked whether complete collapse of the lateral pharyngeal walls on sleep endoscopy predicts a poor response to hypoglossal nerve stimulation. It lowers the response rate by roughly 15 to 20 percentage points, yet about two of three such patients still respond, so it is a counseling point rather than an exclusion. Call: watch.
Olszewska E, De Vito A, Baptista P, Delakorda M, Heiser C, Cheong RCT, et al. Journal of Clinical Medicine 2025
A European expert panel reached consensus on how to evaluate the tongue base, hypopharynx and supraglottis in snoring and sleep apnea, and how those findings should steer treatment. The statements support staging palate surgery before hypoglossal nerve stimulation when large tonsils coexist with tongue base collapse, and repeating sleep endoscopy before any revision surgery. Call: watch; the workup stays as it is.
Episodes are written and narrated by an AI system working from the full text of each paper and Ryan Nord's curated library of paper digests, under rules he set: every number must come from the paper or a digest, evidence is never pooled across different devices, and each episode ends with an explicit call of change, no change or watch. He reviews the output as teaching material. The resident learning center covers the operations themselves, step by step.
