Surgery may be a good way to treat some types of obstructive sleep apnea (OSA), especially when other methods, like CPAP or lifestyle changes, have not worked well enough. During surgery, tissue in the throat that blocks the airway is removed or moved. Common treatments include uvulopalatopharyngoplasty (UPPP) and maxillomandibular advancement. Surgery isn't right for everyone, though, and how well it works depends on the person's anatomy and how bad the problem is. Because of this, a full evaluation by a medical professional is needed to decide if surgery is the right choice for a certain patient. Buy modalert 200
