Evaluation of combined medical and surgical treatment in nasal polyposis - III. Correlation between symptoms and CT scores before and after surgery for nasal polyposis.

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.
