Complete concentric collapse at the soft palate in sleep endoscopy: what change is possible after UPPP in patients with CPAP failure?

Sleep & Breathing = Schlaf & Atmung

Abstract

The aim of this work was to assess whether uvulopalatopharyngoplasty in patients with failure for positive airway pressure not only reduces the degree of obstructive sleep apnea but also to determine as well if it changes the collapse pattern of the soft palate and thereby fulfills the qualifications for implementing upper airway stimulation (UAS) as an adjunctive solution. Fifteen patients with intolerance for positive airway pressure were included in this retrospective cohort study. Polygraphy and drug-induced sleep endoscopy were used in order to evaluate the reduction of the apnea-hypopnea index (AHI), as well as the change of collapse pattern at the soft palate level before and about 3 months after uvulopalatopharyngoplasty and tonsillectomy (TE-UPPP). In 93% of the patients, a postoperative change of the initially complete concentric palatal collapse pattern could be found during drug-induced sleep endoscopy. In one patient, no obstruction at all was seen at the soft palatal level. Only one patient still presented with a complete concentric collapse at velum level. AHI decreased from mean 34.7 events per hour to 20.2/h and oxygen desaturation index from 25.3 events per hour to 16.1/h. Patients seeking for positive airway ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
