Quality of life in CRSwNP: evaluation of ACCESS and Lund-Mackay computed tomography scores versus the QoL questionnaire
Abstract
PURPOSE: Recently, a new CT scan classification of the extent of previous endoscopic sinus surgery called The Amsterdam Classification of Completness of Endoscopic Sinus Surgery (ACCESS) was published. The aim of this study was to investigate possible associations between traditionally used Lund-Mackay CT score and ACCESS score and their possible relationship to pre- and postoperative quality of life in a narrowly defined group of patients with recurrent CRSwNP.
METHODS: Forty-nine patients who underwent a revision ESS for CRSwNP were enrolled in a retrospective study. CT imaging scans were evaluated, LM and ACCESS scores determined.
All patients completed the validated Czech version of the SNOT-22 questionnaire before and 6 months after surgery. The correlation between the two CT scores and the QoL questionnaire was tested using Pearson's correlation tests.
RESULTS: No correlation was demonstrated between LM scores and patient-based SNOT-22 scores neither preopratively nor postoperatively (r = - 0.0580; p = 0.918 and r = 0.0252; p = 0.8634, respectively. Similarly, no correlation was found between the ACCESS score and SNOT-22 before and after surgery (r = - 0.1988; p = 0.1708 and r = - 0.943; p = 0.5193, respectively).
No linear relationship was demonstrated between the LM score and the ACCESS score (r = 0.075; p = 0.6053). CONCLUSIONS: The results show that even the CT score evaluating the completeness of previous procedures has no linear relationship to the quality of life preoperatively and cannot serve as a predictor for the outcomes of surgical treatment.
This study also confirms that ACCESS evaluates a different aspect of the radiological finding than the traditionally used LM score.
