Abstract:
Hypertrophy of inferior nasal turbinate is one of the most common causes for nasal obstruction (NO). As diode laser has proven to be as effective as any other lasers, our objective was to study various primary outcomes of its use of diode laser like improvement in NO, intraoperative bleeding, postoperative pain, and rapidity of healing. The study was undertaken to compare the various outcomes by diode laser turbinate reduction (LTR) and conventional partial inferior turbinectomy (PIT). A nonrandomized controlled trial was conducted on 2 groups: One group (30 cases) underwent LTR and PIT was performed in the other group (30 cases). The improvement in NO was measured postoperatively up to 6 months. Intraoperative bleeding was measured and postoperative pain scores were assessed each day up to fifth postoperative day. Lastly, rapidity of healing was evaluated until 6 months. Subjective relief of NO was 90.8% in LTR group, whereas it was 65% in PIT group at 6-month follow-up, which was statistically significant (P < .05). Pain scores were higher until 5 days in PIT group compared to LTR group (P = .0001). Intraoperative bleeding mean scores (milliliters) were 8.03 in LTR group compared to 23.29 in PIT group (P = .00001). Rapidity of healing was faster in LTR group with mean scores of 3.03 weeks in comparison to PIT group where it was 6.33 weeks (P = .00001). Compared to the conventional technique, the outcomes were better with diode laser and caused less morbidity.
