Conclusion. Computed tomography (CT) in nasal polyposis (NP) patients has three functions before any treatment. CT
provides objective evidence of the disease and precise topography of the disease, and is an indicator of the disease severity.
After functional endoscopic sinus surgery (FESS), CT is an indicator of the residual disease severity and permits detection
of asymptomatic mucoceles. Objective. NP affects nearly 4% of the population. CT has become the examination of choice
for the exploration of NP. FESS is accepted for NP treatment in the setting of failure of medical management. The aim of
this study was to find out whether any correlation exists between symptom severity and CT scan score before and after
FESS. Patients and methods. A total of 114 CT scans were performed in NP patients without contrast medium before and
after FESS (mean follow-up 5 years), and were scored according to the Lund-MacKay system. Results. Lund-MacKay
scores before treatment ranged from 8 to 24. There was a correlation between symptom and CT scores before any
treatment. Postoperative Lund-MacKay scores ranged from 0 to 24. There was a correlation between symptom and CT
scores after surgery. There was no correlation between postoperative symptom and baseline CT scores. Eleven asymptomatic
mucoceles were found |
