Abstract
Background: Nasal polyps have an incidence of 4% in all of the population. Apart from the surgery performed, some patients will present with recurrence. Recurrence ranged from 4 to 60% in nasal polyps (NP), with a median of 20%, across all studies reviewed over a maximum of 2 years.
Objective: The aim was to review cases of recurrent bilateral nasal polyposis in terms of the incidence of local factors contributing to recurrence.
Patients and methods: This prospective study included 50 adult patients (males and females) experiencing recurrent BNP after previous functional endoscopic sinus surgery. The patients were recruited from the outpatient clinic, Otorhinolaryngology Department, Kobry El‑Kobba Military Hospital. The mean age of primary disease was 39 years. There were significant differences between endoscopic and computed tomography (CT) findings according to the presence of different local factors contributing to recurrence of NP, in the form of lateralized middle turbinate, residual infected air cells, scarred frontal recess, middle meatal antrostomy stenosis, retained uncinate process, and retained agar nasi cells. The detection rate of endoscopy was higher than the CT scan.
Results: The most frequent finding was lateralized middle turbinate (74.0%) followed by residual infected air cells and scarred frontal recess (60.0% for each). Middle meatal antrostomy stenosis was found in 40.0% of cases. Retained agar nasi cells was found in 48.0% of cells, whereas retained uncinate process was found in only 36.0% of cases.
Conclusion: There were significant differences between endoscopic and CT findings according to the presence of different local factors contributing to recurrence of NP, in the form of lateralized middle turbinate, residual infected air cells, scarred frontal recess, middle meatal antrostomy stenosis, retained uncinate process, and retained agar nasi cells. The detection rate of endoscopy was higher than the CT scan.
