Apnea–hypopnea index decreased significantly after nasal surgery for obstructive sleep apnea

Apnea–hypopnea index decreased significantly after nasal surgery for obstructive sleep apnea

BACKGROUND Nasal surgeries have been applied to obstructive sleep apnea (OSA) patients with nasal obstruction for decades. However, the efficiency of nasal surgery in improving OSA remains controversial.The aim of this study was to identify whether isolated nasal surgery can improve apnea-hypopnea index (AHI). METHODS Computerized searches were performed in MEDLINE, Web of Science, Cochrane L...

Is Apnea-Hypopnea Index a proper measure for Obstructive Sleep Apnea severity?

Nasal resistance in obstructive sleep apnea.

BACKGROUND Acute increases in nasal resistance are known to induce upper airway occlusion in predisposed subjects. With the limited efficacy of nasal surgery alone in the treatment of obstructive sleep apnea (OSA), the relevance of chronically increased nasal resistance in the pathophysiologic features of OSA remains undetermined. METHODS Seventy-one patients with OSA (apnea+hypopnea index > ...

Changes in the Reflux Symptom Index After Multilevel Surgery for Obstructive Sleep Apnea

OBJECTIVES This study evaluated whether the symptoms of laryngopharyngeal reflux (LPR) change after multilevel surgery for obstructive sleep apnea (OSA). METHODS Patients who underwent multilevel surgery for OSA between April 2009 and September 2014 were enrolled in this study. All patients underwent preoperative polysomnography prior to surgery and were asked to complete the reflux symptom i...

Does nasal decongestion improve obstructive sleep apnea?

Whether nasal congestion promotes obstructive sleep apnea is controversial. Therefore, we performed a randomized placebo-controlled cross-over trial on the effects of topical nasal decongestion in patients with obstructive sleep apnea syndrome (OSA) and nasal congestion. Twelve OSA patients with chronic nasal congestion (mean +/- SD age 49.1 +/- 11.1 years, apnea/hypopnea index 32.6 +/- 24.5/h)...
