Fibronasolaringoscopia en el diagnóstico de syndrome de apnea-hipopnea obstructiva del sueño (SAHOS)

In patients diagnosed with sleep-disordered breathing (SDB), no anatomical findings can be associated with the severity of the pathology or the surgical success. Current advances in video technology have allowed a more accurate assessment of airway measurements and a more accurate map of the specific site of obstruction. Fibronasolaryngoscopy is an affordable and economical technique for evaluating the airway in multiple positions during sleep and wakeful periods; this requires a thorough understanding of the anatomy and physiology of the upper airway by the examiner to determine the exact sites of obstruction and patterns of collapse that could lead to a possible surgical management of the condition, making this diagnostic examination a fundamental part of the study of patients with SDB.
