The fiberoptic nasal endoscopy with modified Muller maneuver (FNMM) scores were 4/4, 4/4, and 3/4 for retropalatal, retrolingual
, and lateral pharyngeal wall collapse, respectively.
A glossectomia da linha media (GLM) robotica e/ou a laser visa criar um alargamento de VAS retrolingual
. As cirurgias que abordam a base de lingua quando realizadas de forma isolada nao levam a sucesso absoluto, ja que obstrucao das VAS na maioria das vezes ocorre em sitios multiplos.
Little change in the retropalatal and retrolingual
dimensions might happen due to small mandibular advancement (MEHRA et al., 2001).
These include uvulopalatopharyngoplasty, which resects the mafia, retrolingual
, and palatine tonsillar tissue; septoplasty; rhinoplasty; nasal turbinate reduction; nasal polypectomy palatal advancement pharyngoplasty; tonsillectomy; adenoidectomy; palatal implants; tongue reduction; genioglossus advancement; and maxillomandibular advancement.
The idea of restoring the retrolingual
space acting on the hyoid bone was codified by Riley et al.
Sagittal or cross-sectional images of the retropalatal and retrolingual
regions (26,27) were obtained to determine the sites of narrowing, as well as the width of the tongue and UA muscle.
A patient who has clear-cut retrolingual
collapse or clear-cut macroglossia should not be offered UP3 at all, either outpatient or inpatient.
Exclusion criteria included previous palatal surgery, the presence of a retrolingual
obstruction, and the presence of a chronic disease that prevented surgery.
Hypopharyngeal obstruction of the retrolingual
area is commonly encountered in the snoring and OSA population.
(10) A meta-analysis by Sher et al found that the success rate of UPPP was 41%, although it was as low as 5% in patients with excessive retrolingual
collapse observed during endoscopy.
Schwab and Goldberg described a model for the pathogenesis of OSA in adults as the closure of the retropalatal and/or retrolingual
(1) But for patients with a retrolingual
narrowing or collapse, with or without a retropalatal component (Fujita type IIb or III obstruction), the UPPP response rate is only 5.3%.
