Results: Compared to the retroglossal airway, the retropalatal airway was smaller at end-expiration (p < 0.001), and had greater absolute and relative compliances (p < 0.001). NED was positively associated with retropalatal relative area change (r = 0.47; p < 0.001).

Sep 16, 2022 · The retropalatal and retroglossal spaces are the main affected areas in obstructive sleep apnea (OSA) and they are the main targeted regions during OSA surgeries. But the dimensions of these spaces are sparsely referred to in literature.

Our clinical data also revealed that ESP-induced upper airway extension was evident in both the retropalatal and retroglossal areas in patients with OSA with lateral pharyngeal collapse.

ObjectiveTo describe our experience treating retroglossal and base-of-tongue collapse in children and young adults with obstructive sleep apnea using combined genioglossus advancement (Repose THS; MedtronicENT, Jacksonville, Florida) and radiofrequency ablation of …

Maxillary advancement in patients with UCL/P produces statistically significant increases in the retropalatal (volumetric and MCA), retroglossal (volumetric and sagittal), and total (volumetric and sagittal) airways based on data from CBCT imaging.

Through this prospective study, we found that bimaxillary surgery caused upper airway narrowing at the retropalatal or retroglossal level and reduced total upper airway volume triggering snoring and OSA in class III malocclusion subjects.

Using fast multidetector CT, we obtained images of the upper airway in the waking and sleep states. Results: Upper airway narrowing during sleep was significantly greater at the retropalatal level than at the retroglossal level in the OSA group (p < …

Retroglossal fat tissue volume (FV) was segmented with Amira software and separated into subcutaneous and internal fat volume (SFV, IFV). These volumes were normalized by retroglossal neck volume (NV). Men had 51.9% more IFV/NV and 64.4% less SFV/NV compared to …

First, the pattern (anteroposterior, lateral, and concentric) and degree (I, 0–25%; II, 25–30%; III, 50–75%; IV, 75–100%) of retropalatal obstruction were evaluated, followed by an evaluation of retroglossal obstruction.

Background: The retropalatal and retroglossal spaces are the main afected areas in obstructive sleep apnea (OSA) and they are the main targeted regions during OSA surgeries. But the dimensions of these spaces are sparsely referred to in literature.
