The laser and the nasal septum--a histological study
The Journal of Otolaryngology
|February 1, 1980
Summary
The carbon dioxide (CO2) laser is safe for nasal septum treatment at four watts with up to three bursts. Higher energy levels or more bursts can cause cartilage damage, necessitating careful histological examination for optimal settings.
Area of Science:
- Otolaryngology
- Laser Surgery
- Histopathology
Background:
- The carbon dioxide (CO2) laser is utilized for various surgical applications.
- Its specific effects on nasal septum cartilage require detailed investigation.
Purpose of the Study:
- To histologically evaluate the effects of CO2 laser irradiation on rabbit nasal septa.
- To determine safe and effective parameters for CO2 laser use in treating anterior septal lesions.
Main Methods:
- Nine rabbits underwent CO2 laser irradiation on their nasal septa.
- Histopathological examination was performed to assess tissue response.
- Different energy levels and burst counts were applied.
Main Results:
- CO2 laser use with up to three bursts at four watts resulted in prompt and complete healing.
- More than three bursts at four watts led to cartilage necrosis.
- Histological examination revealed dose-dependent tissue damage.
Conclusions:
- The CO2 laser can be a safe and effective tool for anterior septal lesions when used with appropriate settings.
- Establishing optimal laser parameters requires thorough histological assessment.
- Careful control of energy delivery is crucial to prevent cartilage necrosis.
