Outcome Prediction Model for Radiofrequency Uvulopalatopharyngoplasty with Tonsillectomy in Adult Obstructive Sleep Apnea: Retrospective Cohort Study.

Introduction: Knowing an individualized outcome prediction is essential when counseling patients before surgery. We aim to identify predictors and build a model for the outcome of radiofrequency uvulopalatopharyngoplasty with tonsillectomy (rfUPPP + TE).

Methods: All adult patients undergoing rfUPPP + TE for sleep-disordered breathing from 2015 to 2022 in our institution were included.

Long-term night-to-night variability of sleep-disordered breathing using a radar-based home sleep apnea test: a prospective cohort study.

Study Objectives: Night-to-night variability of sleep-disordered breathing limits the diagnostic accuracy of a single measurement. Multiple recordings using a reliable, affordable method could reduce the uncertainty and avoid misdiagnosis, which could be possible with radar-based home sleep apnea testing (HSAT).

Methods: We recruited consecutive patients with suspected sleep-disordered breathing and performed contactless radar-based HSAT with automated scoring (Sleepiz One; Sleepiz AG, Zurich, Switzerland) over 10 nights.

Treatment of Residual Palatal Collapse in Hypoglossal Nerve Stimulation Using a Palatal Device.

Hypoglossal nerve stimulation (HNS) has increasingly become an alternative therapy for obstructive sleep apnea patients with CPAP intolerance. Stimulation of the hypoglossal nerve during sleep enhances airway patency and alleviates collapse. Suboptimal responses to HNS often stem from insufficient palatal coupling and residual velar collapse.

Tonsil volume and outcome of radiofrequency uvulopalatoplasty with or without tonsillectomy in adults with sleep-disordered breathing.

Purpose: Predictors for the outcome of uvulopalatopharyngoplasty with and without tonsillectomy (UPPP ± TE) in sleep-disordered breathing have not been fully established. This study investigates tonsil grade, volume, and preoperative examination in predicting radiofrequency UPP ± TE outcomes.

Methods: All patients undergoing radiofrequency UPP with tonsillectomy if tonsils were present between 2015 and 2021 were retrospectively analyzed.

The Otoprotective Effect of Ear Cryotherapy: Systematic Review and Future Perspectives.

This systematic review investigates ear cooling and cryotherapy in the prevention and treatment of inner ear damage and disease, within the context of animal models and clinical studies. A literature search was carried out in the databases Pubmed and Cochrane Library. Ten studies were identified concerning the otoprotective properties of cryotherapy.

Home sleep apnea testing with peripheral arterial tonometry to assess outcome in upper airway stimulation.

Study Objectives: To determine whether home sleep apnea testing with peripheral arterial tonometry (HSAT-PAT) can be used in upper airway stimulation to evaluate therapy success.

Methods: Data analysis from 50 consecutive patients receiving upper airway stimulation was performed. Baseline values were measured by polysomnography and HSAT-PAT.

Does a Low-Cost Act of Support Produce Slacktivism or Commitment? Prosocial and Impression-Management Motives as Moderators.

Increase or decrease in subsequent action following a low-cost act of support for a cause can be predicted from both commitment theory and the slacktivism effect. In this paper, we report on three studies that tested type of motivation (prosocial vs. impression management) as a moderator of the effect of an initial act of support [wearing a badge (S1) and writing a slogan (S2 and 3)] has on support for blood donation.

Clinical impact of manual scoring of peripheral arterial tonometry in patients with sleep apnea.

Purpose: The objective was to analyze the clinical implications of manual scoring of sleep studies using peripheral arterial tonometry (PAT) and to compare the manual and automated scoring algorithms.

Methods: Patients with suspected sleep-disordered breathing underwent sleep studies using PAT. The recordings were analyzed using a validated automated computer-based scoring and a novel manual scoring algorithm.

Evaluation of a nasopharyngeal stent in patients with obstructive sleep-related breathing disorders.

Objective: This study was performed to evaluate the therapeutic effect and diagnostic value of a novel nasopharyngeal stent (Naśtent; Corinium Medical Equipment Ltd., Cirencester, UK). The Naśtent is designed to stent palatal collapse in patients with sleep-related breathing disorders.

Night-to-night variability in obstructive sleep apnea using peripheral arterial tonometry: a case for multiple night testing.

Study Objectives: Night-to-night variability of obstructive sleep apnea severity is considerable and may depend on the diagnostic modality used. We investigated the night-to-night variability using peripheral arterial tonometry (PAT).

Methods: Home sleep apnea testing was performed in 51 patients during 3 consecutive nights using PAT.

Comparison of Traditional Upper Airway Surgery and Upper Airway Stimulation for Obstructive Sleep Apnea.

Objective: To compare patients with moderate-severe obstructive sleep apnea (OSA) undergoing traditional single and multilevel sleep surgery to those undergoing upper airway stimulation (UAS).

Study Design: Case control study comparing retrospective cohort of patients undergoing traditional sleep surgery to patients undergoing UAS enrolled in the ADHERE registry.

Setting: 8 multinational academic medical centers.

Tonsil size and outcome of uvulopalatopharyngoplasty with tonsillectomy in obstructive sleep apnea.

Objectives/hypothesis: To investigate the relationship of tonsil volume and grade on outcomes of uvulopalatopharyngoplasty (UPPP) with tonsillectomy in patients with obstructive sleep apnea (OSA).

Study Design: Retrospective cohort analysis.

Methods: Data of 70 consecutive patients undergoing UPPP with tonsillectomy between 2015 and 2018 were analyzed.

Contribution of Hyoid and Tonsillar Procedures to Outcome in Multilevel Surgery for Obstructive Sleep Apnea Syndrome.

Background/objective: In multilevel surgery for obstructive sleep apnea (OSA), the contribution of distinct operative steps is still unclear. The aim of the present study is to retrospectively compare different combinations of multilevel surgeries in order to estimate the contribution of hyoid and tonsillar procedures to the outcome.

Methods: A total of 45 patients were selected in a retrospectively matched case-control study from a database of patients who underwent surgery for OSA at our institution: group A (n = 15) had hyoid suspension, tonsillectomy, and radiofrequency-assisted uvulopalatoplasty (RAUP); group B (n = 15) had hyoid pharyngoplasty with resection of the hyoid body and preepiglottic fat tissue, tonsillectomy, and RAUP; and group C (n = 15) had hyoid suspension and RAUP but no tonsillectomy, because the tonsils had already been removed.

[Topical application of tranexamic acid to prevent post-tonsillectomy haemorrhage].

Background: Haemorrhage after tonsillectomy (TE) is a frequent and possibly major complication. The aim of the present study was to examine, if the rate of haemorrhage after tonsillectomy could be reduced by the topical application of Tranexamic acid (TXA) postoperatively.

Material And Methods: Between November 2011 and April 2013, all patients (n=246) received TXA postoperatively to prevent haemorrhage after TE.

Modification of the Hörmann technique of hyoid suspension in obstructive sleep apnoea.

Hyoid suspension is a procedure to stabilise the retrolingual space in obstructive sleep apnoea. Using the Hörmann technique, a steel wire is slung around the body of the hyoid and fixed to the upper rim of the thyroid cartilage. It was observed, however, that the steel wire may lie very superficially to the pharyngeal mucosa.

[Influence of intraoperatively applied current of coagulation on the postoperative course in tonsillectomy].

Background And Methods: Postoperative pain after tonsillectomy is greater using diathermy compared to the use of ligatures for hemostasis. In the present paper, the influence of coagulation current on the postoperative course is assessed quantitatively. The applied coagulation current was registered in Watt per second (Ws) in 63 patients.
