ABSTRACT
INTRODUCTION: Surgical treatment of medium and large sized nasal septal perforation is challenging. Techniques with and without interposition grafts are used.
OBJECTIVE: The aim of this study is to explain how we apply the sandwich graft technique that we use in medium and large nasal septal perforations as well as to present the results.
METHODS: We retrospectively reviewed the patients who were operated with the sandwich graft technique between January 2014 to December 2018 and followed up for at least 6 months. The demographic data, symptom scores, examination, and surgical findings of the patients were taken from the hospital records. Surgical outcomes were presented according to both perforation etiologies (idiopathic or iatrogenic) and sizes (Group A: < 2 cm, Group B: ≥ 2 cm).
RESULT S: We reviewed 52 cases and 56 surgeries. The average diameter of the perforations was 19.2 mm. The success rate after initial surgeries was 84.6% (44/52). After 4 revision surgeries, the perforation was closed in 88.5% of the cases (46/52). Success rates for Group A and Group B were 90.0% and 86.4%, respectively (p = 0.689). The success rates in idiopathic and iatrogenic cases were 93.3% and 86.5%, respectively (p = 0.659).
CONCLUSION: This study showed that the success rate of sandwich graft technique was higher in medium-sized perforations than large-sized ones and in idiopathic perforations compared to iatrogenic ones, but the latter rate was not statistically significant. This demonstrated that perforation size was not as important in the sandwich graft technique as in flap techniques.
