Cone-beam computed tomography texture analysis can help differentiate odontogenic and non-odontogenic maxillary sinusitis

Abstract

Purpose This study aimed to assess texture analysis (TA) of cone-beam computed tomography (CBCT) images as a quantitative tool for the differential diagnosis of odontogenic and non-odontogenic maxillary sinusitis (OS and NOS, respectively). Materials and Methods CBCT images of 40 patients diagnosed with OS (N=20) and NOS (N=20) were evaluated. The gray level co-occurrence (GLCM) matrix parameters, and gray level run length matrix texture (GLRLM) parameters were extracted using manually placed regions of interest on lesion images. Seven texture parameters were calculated using GLCM and 4 parameters using GLRLM. The Mann-Whitney test was used for comparisons between the groups, and the Levene test was performed to confirm the homogeneity of variance (α=5%). Results The results showed statistically significant differences ( P <0.05) between the OS and NOS patients regarding 3 TA parameters. NOS patients presented higher values for contrast, while OS patients presented higher values for correlation and inverse difference moment. Greater textural homogeneity was observed in the OS patients than in the NOS patients, with statistically significant differences in standard deviations between the groups for correlation, sum of squares, sum of entropy, and entropy. Conclusion TA enabled quantitative differentiation between OS and NOS on CBCT images by using the parameters of contrast, correlation, and inverse difference moment.

Diagnostic criteria for odontogenic sinusitis: narrative review of relevant literature data

“…Such outcome may be caused by the absent cortical plate between problematic tooth and affected sinus [3] (Figure 5). On the CBCT scans patients with odontogenic sinusitis represent higher values of textural homogeneity, while non-odontogenic sinusitis patients demonstrated greater levels of contrast [20].…”

The Place of Radiation Imaging in the Differential Diagnosis of Odontogenic Maxillary Sinusitis

“…Больные с воспалительными заболеваниями параназальных синусов составляют около 1/3 общего числа пациентов, госпитализированных в стационары с заболеваниями верхних дыхательных путей [1]. Преобладающим по частоте вовлечения в воспалительный процесс большинство авторов считают верхнечелюстной синус [2].…”
