Abstract

Enlargement of inferior nasal turbinates is a common cause of nasal obstruction. Surgical methods used to treat hypertrophied inferior turbinates such as electrocautery, cryosurgery, partial turbinectomy, laser turbinoplasty, microdebrider reduction and radiofrequency thermal ablation (RFTA).The mucosal condition after surgery is an important factor that should be considered in evaluation of different techniques. This study aimed to examine the microstructural appearance of the ciliated epithelial tissues by light microscope.It was done by cytological examination of inferior turbinate mucosain patients treated by radiofrequency thermal ablation (RFTA) and bipolar electrocautery (BEC) of hypertrophied inferior turbinates. A prospective study included thirty six patients with hypertrophied inferior turbinates causing nasal obstruction not responding to medical treatment. Patients were divided into two groups: group(A) were managed with radiofrequency thermal ablation (RFTA)and group (B)were managed with bipolar electrocautery (BEC).Routine nasal examination was done with the aids of anterior rhinoscopy and nasal endoscopy. The postoperative follow up period wasthree months. cytological examination of nasal mucosa was done postoperatively. Results: there was no abnormalities in ciliated epithelial cells and only 12% of cases showed abnormalities in the form of damage in the ciliated cellswith anarchitectural rearrangement.While, the majority of sample showed abnormalities in cilia and epithelial cell damage. 78% of patients had abnormal ciliated epithelial cells im group B. Radiofrequency thermal ablation seems to be a good modality dealing with the problem of inferior turbinate hypertrophy. It showed minimal injury to turbinatemucosal tissues with good ciliary structure, along with an intact and functioning epithelium.
