Abstract

Background

Although continuous positive airway pressure (CPAP) therapy curtails most of the negative impacts of obstructive sleep apnea (OSA), its efficacy is limited by its low long-term adherence. Nasal obstruction contributes to OSA pathophysiology and necessitates high CPAP titration pressures which reduce CPAP compliance.

Aim

This study aims at elucidating the outcomes of surgical correction of nasal obstruction in patients intolerant to CPAP therapy.

Methods

Forty-nine patients with severe OSA intolerant to CPAP secondary to surgically correctable nasal obstruction were operated upon. Patients were evaluated preoperatively and at least 3 months after the surgical intervention. Subjective assessment entailed the Nasal Obstruction Symptom Evaluation score (NOSE) and the Epworth Sleepiness Scale (ESS). Objectively the patients were assessed by acoustic rhinometry and standard polysomnography.

Results

Nasal surgical intervention resulted in an a statistically significant decrease in the mean NOSE score, ESS and optimal CPAP titration pressure. In addition, the minimal cross-sectional area (MCA1&2) increased significantly postoperatively. There was a positive correlation between the improvement in NOSE score as well as the MCA1& 2 and the postoperative decrease in CPAP titration pressure. Surgical correction of nasal obstruction improved CPAP outcomes and compliance in all patients.

Conclusions

Nasal surgery in OSA objectively assessed by acoustic rhinometry improved nasal obstruction with a resultant decrease in the CPAP pressure requirements. Given that lower CPAP pressures improve adherence to CPAP therapy, surgical alleviation of nasal obstruction should be considered a crucial intervention in the management armamentarium of OSA.

Verbände und Cremes gegen Dekubitus: „Wir wissen nicht, was sie bringen!“

Die Datenlage zur Wirksamkeit von Verbänden oder topischen Mitteln zur Prävention von Druckgeschwüren sei schlecht, so die Verfasser einer aktuellen Cochrane-Studie. Letztlich bleibe es unsicher, ob solche Maßnahmen den Betroffenen nutzen oder schaden.

Schützt das tägliche Glas Milch vor Darmkrebs?

Die Milch machts – sie bietet Frauen nach Daten einer großen Ernährungsanalyse den besten Darmkrebsschutz aller Lebensmittel, was am hohen Kalziumgehalt liegen dürfte. Am anderen Ende des Spektrums steht der Alkoholkonsum: Das Glas Wein am Abend ist eher ungünstig.

Vorsicht mit Glukokortikoiden bei Glomerulopathie

Auch niedrig dosierte Glukokortikoide zur Behandlung einer primären Glomerulopathie lassen offenbar die Infektionsgefahr steigen. In einer US-Studie hing das Risiko vor allem mit der kombinierten Anwendung von Immunsuppressiva zusammen.
