Mucosal changes in chronic hypertrophic rhinitis after surgical turbinate reduction

Area of Science:

• Rhinology
• Otolaryngology
• Surgical Pathology

Background:

• Chronic hypertrophic rhinitis frequently causes nasal obstruction.
• Conservative treatments are often ineffective for this condition.
• Surgical turbinate reduction is a common treatment, but its histological effects are understudied.

Purpose of the Study:

• To compare the postoperative histological effects of submucosal monopolar diathermy, radiofrequency coblation, and ultrasound on nasal mucosa.
• To evaluate the regenerative capacity of the nasal epithelium after different turbinate reduction techniques.

Main Methods:

• Sixty patients with chronic hypertrophic rhinitis underwent turbinate reduction using ultrasound, monopolar diathermy, or radiofrequency coblation.
• Nasal mucosal specimens were collected preoperatively and at 1, 3, and 6 months post-surgery.
• Electron microscopy was used to examine epithelial changes, intercellular edema, mucus production, and collagen deposition.

Main Results:

• Preoperative mucosa showed epithelial degeneration, cilia loss, and inflammation.
• Postoperative specimens revealed reduced edema, less mucus, increased collagen, and flattened epithelium.
• Ultrasound treatment showed some areas of normally organized columnar ciliated epithelium.

Conclusions:

• Turbinate tissue volume reduction offers minimal improvement in epithelial changes associated with chronic hypertrophic rhinitis.
• Ultrasound techniques demonstrated limited epithelial regeneration in some cases, potentially restoring nasal physiology.
