Pang-Rotenberg sign--snoring surgery prognosticator: A prospective clinical trial of 153 patients.

Objectives/hypothesis: To illustrate the reliability of the Pang-Rotenberg (PR) sign as a prognosticator of snoring surgery. Our hypothesis was that patients who are PR-positive have better snoring reduction scores and outcomes than PR-negative patients after nose and palate surgery.

Study Design: A multicenter prospective series of 153 patients with snoring.
