Endoscopic septoplasty has become the favored approach for the treatment of a deviated septum. Careful septal dissection results in less bleeding, clear endoscopic view, shortened operative time, and fewer postoperative complications. We describe our 5-year experience of using an 8 French Frazier suction tube for submucosal dissection compared with the traditional septoplasty. A total of 434 patients who underwent septoplasty were recruited. The patients in the study were divided into two Groups 1 and 2 based on the employed surgical techniques to treat deviated nasal septum: traditional septoplasty (Group 1: 105 patients) and suction-tube-assisted endoscopic septoplasty (Group 2: 329 patients). All the patients were followed up for a minimum of 6 months. No statistically significant differences could be traced between the groups in any demographic factor, regarding the gender, age, and the intraoperative and postoperative complications. A significantly shorter operative time was found in Group 2 (P < 0.001). The overall incidence of minor complications was 6.6% in Group 1 and 4.6% in Group 2. The suction-tube-assisted dissection technique is found to be a surgical alternative, effective with a significantly shorter operating time, and economical option in septal surgery.

For chronic rhinitis that is refractory to medical therapy, surgical intervention such as endoscopic vidian neurectomy (VN) can be used to control the intractable symptoms. Lasers can contribute to minimizing the invasiveness of ENT surgery. The aim of this retrospective study is to compare in patients who underwent diode laser-assisted versus traditional VN in terms of operative time, surgical field, quality of life, and postoperative complications. All patients had refractory rhinitis with a poor treatment response to a 6-month trial of corticosteroid nasal sprays and underwent endoscopic VN between November 2006 and September 2015. They were non-randomly allocated into either a cold instrument group or a diode laser-assisted group. Vidian nerve was excised with a 940-nm continuous wave diode laser through a 600-mu m silica optical fiber, utilizing a contact mode with the power set at 5 W. A visual analog scale (VAS) was used to grade the severity of the rhinitis symptoms for quality of life assessment before the surgery and 6 months after. Of the 118 patients enrolled in the study, 75 patients underwent cold instrument VN and 43 patients underwent diode laser-assisted VN. Patients in the laser-assisted group had a significantly lower surgical field score and a lower postoperative bleeding rate than those in the cold instrument group. Changes in the VAS were significant in preoperative and postoperative nasal symptoms in each group. The application of diode lasers for vidian nerve transection showed a better surgical field and a lower incidence of postoperative hemorrhage. Recent advancements in laser application and endoscopic technique has made VN safer and more effective. We recommend this surgical approach as a reliable and effective treatment for patients with refractory rhinitis.
