Little change in the retropalatal and retrolingual
dimensions might happen due to small mandibular advancement (MEHRA et al.
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.
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.
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.
Schwab and Goldberg described a model for the pathogenesis of OSA in adults as the closure of the retropalatal and/or retrolingual
Hypopharyngeal obstruction of the retrolingual
area is commonly encountered in the snoring and OSA population.
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.
According to a report cited by Nelson, the uvulopalatopharyngoplasty (UPPP) response rate in patients with a retrolingual
narrowing or collapse, with or without a retropalatal component, is:
The anatomic areas most often implicated in snoring are the retropalatal pharynx and retrolingual
