Statistical model for postoperative apnea-hypopnea index after multilevel surgery for sleep-disordered breathing.

The objective of the study was to formulate a statistical model for postoperative apnea-hypopnea index (AHI) 3 and 12 months after multilevel surgery using the predictors preoperative AHI, body mass index (BMI) and age. The study design was a prospective cohort study. Data of 144 patients were collected prospectively 3 and 12 months after multilevel surgery for obstructive sleep apnea syndrome (OSAS) or upper airway resistance syndrome with excessive daytime sleepiness.

Therapy of snoring and obstructive sleep apnea using the Velumount palatal device.

Objectives: The aim of the present study is to investigate the efficacy of the Velumount device.

Methods: In a prospective cohort study 40 patients were examined with and without Velumount. The apnea-hypopnea index and average esophageal pressure were measured using nocturnal manometry of the upper airways, combined with respiratory polygraphy.

Outcome of functional endonasal sinus surgery with and without CT-navigation.

Introduction: Computer-assisted surgery (CAS) has found widespread use in functional endonasal sinus surgery (FESS) over the past few years. The present study investigates if CAS leads to a better outcome in FESS.

Material And Methods: All patients who underwent endonasal sphenoethmoidectomy were enrolled in a prospective, non-randomized case-control study.
