Study Objectives: Effective treatment of obstructive sleep apnea depends on efficacy and adherence. The objective of this analysis was to examine the association between adherence to unilateral hypoglossal nerve stimulation (Inspire upper airway stimulation) and changes in daytime sleepiness.
Methods: Participants were adults treated with unilateral hypoglossal nerve stimulation enrolled in the ADHERE Registry. All participants included in the analysis completed a final visit 1-2 years following implantation. Outcomes were the change in Epworth Sleepiness Scale (ESS) score and normalization of a baseline abnormal ESS score (baseline ESS > 10 and final ESS ≤ 10). Statistical analyses examined the association between objective therapy adherence and ESS outcomes, with multiple regression including adjustment for age, sex, race, ethnicity, body mass index, and apnea-hypopnea index-defined responder status.
Results: The analysis included 1,147 participants who were primarily middle-aged (59.7 ± 10.5 years), overweight (body mass index: 29.1 ± 3.7), White (95.8%), male (76.8%), and with severe obstructive sleep apnea (apnea-hypopnea index: 35.12 ± 14.81). ESS scores decreased from 11.3 ± 5.5 at baseline to 6.9 ± 4.6 at the final visit. Of those with baseline ESS > 10, 68% (441/644) achieved normalized ESS scores at the final visit. Multiple regression analyses showed that each additional hour/night of therapy use was associated with a decrease in ESS score (0.17, = .045) and increased odds of normalized ESS (odds ratio: 1.13; 95% confidence interval: 1.03-1.25). Apnea-hypopnea index response was also associated with a decrease in ESS score (1.29, < .001) and increased odds of a normalized ESS (odds ratio: 2.29; 95% confidence interval: 1.55-3.4).
Conclusions: Adherence to hypoglossal nerve stimulation is associated with improvement in daytime sleepiness symptoms and increased odds of achieving normalization of daytime sleepiness.

Background: Late radiation-associated dysphagia (late-RAD) commonly presents in patients with signs of hypoglossal neuropathy, with hallmark clinical features including lingual atrophy, deviation, and fasciculation. Gold-standard electromyography (EMG) has not been used to explore the frequency of hypoglossal neuropathy in patients with late-RAD.
Methods: Exploratory post hoc secondary analysis of MANTLE trial (NCT03612531) was completed.

Purpose: For submandibular gland resection, conventional surgery with the naked eye remains the standard. With its excellent automatic focus and high magnification, the ORBEYE 3D exoscope enables precise submandibular gland resection with less stress. Therefore, we aimed to examine the usefulness of the exoscope in submandibular gland resection.

Hypoglossal nerve stimulation (HNS) device placement for moderate to severe obstructive sleep apnea has been growing in popularity. The incidence of patients requesting cervical rhytidectomy following implant placement is likely to increase proportionally to the incidence of device placement. This case report describes the preoperative and introperative considerations and details of successful rhytidectomy with platysmaplasty surgery with previous HNS device placement.

Background: Hypoglossal nerve stimulation (HNS) to treat obstructive sleep apnea (OSA) currently requires placement of a cuff or 'saddle' electrode around or adjacent to the hypoglossal nerve(s). Limitations for this therapy include cost, invasiveness, and variable efficacy.
Research Question: Can HNS applied via percutaneous implantation of a linear, multi-pair electrode array restore airflow to airway narrowing and/or obstruction, and improve airway collapsibility in people with OSA?
Study Design And Methods: Participants with OSA undergoing drug induced sleep endoscopy with propofol were instrumented with an epiglottic pressure catheter, nasal mask and pneumotachograph.

Implant extrusion is a rare but serious complication typically linked to infection, poor wound healing, or material intolerance. This case report describes a 79-year-old female patient who experienced extrusion of both a hip prosthesis and an Inspire hypoglossal nerve stimulator (Inspire Medical Systems, Inc., Minnesota, USA), each event associated with the use of Ethibond (Ethicon, Johnson & Johnson, Georgia, USA) sutures.
