Abstract
Nasal obstruction is a very common complaint which may be caused by various causes . But one of the most important causes is septal deviation. Many techniques have been described to correct these septal deviations since the middle of nineteenth century. There have been several modifications since its inception, starting from radical septal resection to mucosal preservation and subsequent preservation of the possible septal framework. The application of endoscopic techniques to correct septal deformities was initially described by both Lanza et al and by Stammberger in 1991. Since that time, many authors began to use an endoscope in correction of septal deviations. The aim of our study was to compare efficacy of endoscopic septoplasty with conventional septoplasty in treating cases having septal deviations. In our study, 60 cases having significant septal deviations were selected. They were divided into two groups: Group A: 30 patients underwent endoscopic septoplasty. Group B: 30 patients underwent conventional septoplasty. Each patient was subjected to a preoperative assessment protocol that included a thorough history taking, general and local examination and nasal endoscopic examination. Postoperatively, all patients were viewed in the outpatient clinic, once weekly for the 1st month then every 2 weeks for 3 months then monthly till 6 months. They were subjected to an assessment protocol similar to the preoperative one. In our study, we didn’t find any significant difference in the preoperative results between both groups as regards age, sex, and types of septal deformities. So, the preoperative circumstances were similar between both groups; consequently any expected difference in the postoperative results would depend mainly on the surgical technique used in each group. Results of our study showed that two procedures were suitable to correct septal deformities. But endoscopic septoplasty was superior to traditional septoplasty in: cases of isolated septal spur, as we make incision on the spur itself. So, less time consuming during operation , less blood loss and less morbidity. Also, it is superior in preventing occurrence of persistent posterior deviations and spurs. By endoscopic examination on last available follow up, no persistent spurs but 6.7 % persistent posterior deviations were found in group A. In group B 16.7% persistent spurs and 26.7% persistent posterior deviations were found. By endoscopic septoplasty, we minimize persistent contact with turbinates as in group A we encountered no cases with persistent contact with turbinates while in group B 20% of cases presented with the former finding.
