Topical treatment with 1% sterile sodium hyaluronate solution applied on the tympanic perforation membrane has been suggested as an alternative to surgical treatment in one study only. To further investigate the effects of such a treatment, we designed a double blind study comparing topical administration of 1% sodium hyaluronate with that of 2% methylcellulose solution (placebo). After treatment the degree of perforation healing was evaluated and expressed in percentage of reduction area. The reduced area turned out to be significantly different in the group treated with sodium hyaluronate solution as compared to the placebo group. We believe that sodium hyaluronate is an alternative to myringoplasty for selected tympanic membrane perforations.
