Polypoid Corditis (Reinke’s Edema)
Reinke’s edema (polypoid corditis) is a voice disorder, in which, gel-like viscous fluid accumulates in the vocal folds, just below the surface of the vocal fold.
Causes of Reinke’s Edema
The most common reasons are cigarette smoking (tobacco use), laryngopharyngeal reflux (backflow og acidic stomach content to the throat) and long term voice overuse or misuse. Repeated or chronic upper respiratory tract infections and frequent throat clearing are also cofactors that can cause Reinke’s edema.
Signs and Symptoms of Reinke’s Edema
The mass and volume of the vocal folds increase. This leads to a lower pitch in the voice. Speaking and singing needs more vocal effort and is instable.
Treatment of Polypoid Corditis
Surgical treatment (phonomicrosurgery) is indicated. However, before and after surgery, the causes that result in the pathology, must be corrected. If the patient quits smoking, if the reflux is treated and if a hygienic vocal behaviour is adapted, recurrence is not likely. If it is done by an experienced surgeon, both vocal folds may be operated simultaneously.
In the early postoperative period, vocal effort may increase for a short period of time. This is secondary to the removal of the oedema, which leaves a gap between the vocal folds that is not present before. This aspect is the most important part of surgery. An important amount of the thin and fragile epithelium covering the oedema must be left in place and should never be resected completely. Further resection may lead to scar and longer lasting vocal problems.
Prognosis and Follow-up in Reinke’s edema
Recurrence of Reinke´s edema is unlikely following a surgery in experienced hands. An important improvement of voice is expected after surgery. Hygienic vocal behaviour, ie. cessation of smoking and proper vocal use elongates these good results.
