Abstract
In sleep apnea/hypopnea syndrome (SAHS) a superior airway collapse can occur in the anteroposterioror lateral direction. The primary or secondary decrease in the tone of the dilating muscles of the pharynx, due to the negative pressure produced by the contraction of the diaphragm cause the collapse. Pharyngoplasty surgical techniques try to improve lateral collapse by repositioning the muscles that constitute the pharyngeal lateral wall, mainly the palatopharyngeal (PP), palatoglossal (PG) and upper constrictor (UC).
Highlights
The collapse of the upper airway that occurs in patients with sleep apnea (SAHS) can be anteroposterior or lateral.The importance of lateral collapse is demonstrated by seeing how continuous positive airway pressure (CPAP) acts by dilating the airway mainly laterally.Most of the surgical techniques used to treat patients with sleep apnea-hypopnea syndrome (SAHS) act by modifying the anteroposterior collapse.Pharyngoplasty are surgical techniques designed to treat the lateral collapse of the pharyngeal wall, modifying the position and the action of the muscles of that region.Citation: Ruggeri CS, López S (2020) Pharyngoplasty in the Treatment of Sleep Apnea: Efficacy of Surgical Techniques
Twenty-four patients with SAHS were treated with pharyngoplasty techniques
If a 50% reduction in apnea/hypopnea index (AHI) is considered, but leaving this index equal or below 10, eight patients had an improvement (53.33%)
