Obstructive sleep apnea is usually the effect of obstruction at many anatomic areas. Palatal, nasal, and hypopharyngeal obstruction is generally considered as a major cause of hypopnea syndrome and snoring. Even in situations where one site is majorly involved, increasing the negative pressure can induce more obstruction in many places. If you consider a surgical control of this disorder, a precise understanding of the complicated relationship in between sites of obstruction is important to the success of the surgery.
Uvulopalatopharyngoplasty (UPPP) is one very common method used in treating this condition. It is a surgical procedure or sleep surgery performed to remove excess tissue in the throat. The purpose of such removal is to widen the airway, to allow air to move through the throat more easily.
It is essential to determine the different sites for obstruction that resulted in the development of various methods that try to predict the upper airway obstruction and location. They are physical examination, snoring sound analysis, magnetic resonance imaging, computed tomography, fluoroscopy, and cephalometry, among others. Although such methods reveal value, many of these procedures mentioned do not claim to be perfect.
More Studies Required
The test is hugely utilized. In spite of this, its utility is not so certain and no studies have been capable of associating such maneuver as equipment for selecting patients. This has been the basis for the method called Friedman tongue positions (FTP). The process of classifying FTP involves asking patients to open their mouths wide without extending the tongue. The process is repeated five times to make the observer capable of assigning the most consistent state as the FTP.
Former studies demonstrate the capacity to separate patients who will reap the benefits of UPPP as one modal treatment from those who will require multilevel surgical solutions. UPPP is one of the most common procedures done by otolaryngologists for treating obstructive sleep apnea hypopnea syndrome. A meta-analysis of unselected patients who have been treated with UPPP showed that only 40.49% of patients underwent successful surgery.
