Diode laser reduction of inferior turbinate hypertrophy offers superior outcomes compared to conventional surgery. This laser technique provides better relief from nasal obstruction, less pain, reduced bleeding, and faster healing.
Area of Science:
- Otolaryngology
- Minimally Invasive Surgery
- Rhinology
Background:
- Inferior turbinate hypertrophy is a primary cause of nasal obstruction.
- Laser-assisted turbinate reduction is an established treatment option.
- Diode laser technology offers potential advantages in turbinate surgery.
Purpose of the Study:
- To compare diode laser turbinate reduction (LTR) with conventional partial inferior turbinectomy (PIT).
- To evaluate outcomes including nasal obstruction, postoperative pain, bleeding, and healing.
- To assess the overall morbidity associated with each procedure.
Main Methods:
- A nonrandomized, controlled trial involving 60 patients.
- 30 patients underwent diode LTR, and 30 underwent conventional PIT.
- Outcomes were assessed postoperatively up to 6 months.
Main Results:
- Subjective nasal obstruction relief was significantly higher in the LTR group (90.8%) versus PIT group (65%) at 6 months (p < 0.05).
- Postoperative pain scores were significantly lower in the LTR group compared to the PIT group (p = 0.0001).
- Intraoperative bleeding was substantially reduced in the LTR group (8.03 ml) versus the PIT group (23.29 ml) (p = 0.00001).
- Healing was markedly faster in the LTR group (mean 3.03 weeks) compared to the PIT group (mean 6.33 weeks) (p = 0.00001).
Conclusions:
- Diode laser turbinate reduction demonstrates superior outcomes compared to conventional partial inferior turbinectomy.
- The diode laser technique results in less morbidity, reduced pain, and faster recovery.
- Diode LTR is an effective and advantageous treatment for inferior turbinate hypertrophy.
