Is there any relationship between the clinical, radiological and histopathologic findings in sinonasal polyposis?

The aim of this study was to assess the relationship between clinical, radiological and histopathological findings in nasal polyposis.

This was a retrospective study of 85 patients with nasal polyposis who were treated by endoscopic sinus surgery between the years of 2005 and 2010. All patients underwent preoperative paranasal sinus Computerized Tomography scan in the coronal plane and these images was evaluated with Lund-Mackay scores. The biopsy materials diagnosed as nasal polyp were identified by archive scanning at the pathology department. The Haematoxylin-Eosin stained preparations of the biopsy materials were re-evaluated. All of the results were analyzed by using the SPSS 13.0 soft ware program. Statistical significance was determined as p-value < 0.05.

When the patients with (16.4%) and without (83.6%) bronchial asthma were compared regarding the eosinophil, lymphocyte, neutrophil, macrophage, mast cells and goblet cells/ epithelial cell rate, no statistical significance was found (p > 0.05). There was a positive relationship between the preoperative complaint durations and the total Lund-Mackay scores (r=0.270, p=0.012). The neutrophil amount (16.53 ± 19.87) on the preparations of the patients with metaplasia was higher than the neutrophil amount (8.71 ± 23.98) on the preparations of the patients without metaplasia (p=0.001). Radiologically, there was a positive correlation between the infiltration of anterior-posterior sinuses by the polyp tissues and the Lund-Mackay score of the nasal cavity.

There was a positive correlation between preoperative complaint duration and squamous metaplasia; and there was also a positive correlation between the preoperative complaint duration and the total Lund-Mackay score. There was no histopathological difference between the polypoid infiltration of the front and rear group sinuses.
