A contemporary review of "realistic" success rates after surgical closure of nasal septal perforations.

The surgical closure of septal perforations is a challenging procedure. Various techniques exist. Each perforation proves that there is not the one precise procedure for all perforations. Nevertheless, success rates of about 90% are reported, although the procedure for closing the defect is challenging. Our goal was to evaluate the existing data. We performed a contemporary review of published closure rates of septal perforations on order to compare the present results in the literature. The limitations of the respective studies were analyzed. We found closure rates from 30 to 100%. Numerous procedures were described and combined. Prospective studies comparing different techniques are missing. The follow-up time in studies was quite short or not even specified. Studies on long-term success rates are rare. The closure of septal defects is one of the most challenging rhinosurgical interventions. Closure rates ≥90% as described in literature seem relatively high. One reason might be short follow-ups and retrospective study designs. Frequently, precise information on the follow-up and the method of follow up is missing. Thoroughly designed prospective studies are absent. Longer follow-up times are associated with lower complete closure rates. A long-term success rate between 70 and 80% seems realistic.
