Chirurgische versus nicht-chirurgische Eingriffe für Stimmlippenknötchen

BACKGROUND:

This is an update of a Cochrane review first published in The Cochrane Library in Issue 2, 2001 and previously updated in 2007 and 2009.
Vocal cord nodules are bilateral, benign, callous-like growths of the mid-portion of the membranous vocal folds. They are of variable size and are characterised histologically by thickening of the epithelium with a variable degree of inflammation in the underlying superficial lamina propria. They characteristically produce hoarseness, discomfort and an unstable voice when speaking or singing.

OBJECTIVES:

To assess the effectiveness of surgery versus non-surgical interventions for vocal cord nodules.

SEARCH METHODS:

We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ISRCTN and additional sources for published and unpublished trials. The date of the most recent search was 9 April 2012.

SELECTION CRITERIA:

Randomised and quasi-randomised trials comparing any surgical intervention for vocal cord nodules with non-surgical treatment or no treatment.

DATA COLLECTION AND ANALYSIS:

No suitable trials were identified.

MAIN RESULTS:

No studies fulfilled the inclusion criteria.

AUTHORS' CONCLUSIONS:

There is a need for high-quality randomised controlled trials to evaluate the effectiveness of surgical and non-surgical treatment of vocal cord nodules.
