ObjectiveTo analyze the usefulness and safety of a steroid injection into vocal nodules via the cricothyroid membrane. Local administration of steroid directly into the larynx has been reported in many laryngeal diseases with different methods.DesignProspective case series at an academic tertiary care hospital.PatientsEighty patients with vocal nodules were enrolled between December 2008 and May 2010.InterventionsTriamcinolone acetonide was injected through the cricothyroid membrane with a transnasal flexible laryngoscope to patients in a sitting position.Main Outcome MeasuresVocal nodules were evaluated before and 2 and 4 weeks after the injection; improvement was assessed both objectively and subjectively.ResultsThe nodules disappeared in 35 patients by the fourth week after the injection (44%), and 39 patients showed improvement (49%). Jitter, shimmer, maximum phonation time, and mean voice handicap index also improved significantly after the steroid injection (P < .05 for all). Six patients with voice-related occupations showed improvement at the second week (8%), but the nodules had recurred after 4 weeks. Four patients experienced mild vocal fold atrophy, and 2 patients showed a white plaque formation on the vocal fold that resolved spontaneously 1 to 2 months after the injection.ConclusionsA local steroid injection via the cricothyroid membrane is a useful and safe treatment option for vocal nodules. However, vocal nodules are caused mainly by excessive voice use; therefore, nodules can recur unless the voice use pattern changes. Further study of this treatment technique, including long-term follow-up, is needed.
