Radiographic evaluation of nasal septal deviation from computed tomography correlates poorly with physical exam findings.

摘要: Background Performance of septoplasty is dependent on objective evidence nasal septal deviation. Although physical examination including anterior rhinoscopy and endoscopic the gold standard for evaluation deviation, third-party payors’ reviews claims are often made computed tomography (CT) findings. However, correlation between radiographic deviation with findings unknown. Methods Retrospective, blinded, independent in 39 consecutive patients from examination, by an otolaryngologist sinus CT scan a neuroradiologist. Four distinct locations (nasal valve, cartilaginous, inferior/maxillary crest osseous septum) were evaluated 4-point scale representing (1) 0% to 25%, (2) >25% 50%, (3) >50% 75%, (4) >75% obstruction. Correlation evaluations was Pearson's quantitative agreement assessed Krippendorf's alpha. Results Statistically significant detected endoscopy assessment only at septum (p = 0.007, r 0.425) low (α 0.290). No cartilaginous 0.286, 0.175), inferior 0.117, 0.255), or valve 0.174, 0.222). Quantitative suggested bias underestimate exam −0.490). Conclusion CT poor substitute standard, Clinical decisions about pursuit approve should not be evidence.
