Radiologic periodontal findings in paranasal sinus computed tomography scans of chronic rhinosinusitis patients

AbstractComputed tomography scans serve as a critical ‘roadmap’ for functional endoscopic sinus surgery. A systematic evaluation of such scans, and an awareness of any anatomical variants that may modify one's surgical approach, allow one to pre-empt complications. This article describes, from a novice's perspective, two methods of evaluating paranasal sinus computed tomography scans: a quick assessment technique; and a step-wise, operative approach covering radiological features relevant to pre- and peri-operative management.

Objectives: To investigate the incidence of accessory maxillary sinus ostia in superior meatus in patients with clinical and radiological signs of maxillary sinusitis and the association with the development of chronic rhinosinusitis. Design: Retrospective study Setting: Tertiary care hospital Participant: 159 patients examined with paranasal sinus computed tomography scans Main outcome measures: We retrospectively evaluated patients who visited the outpatient department at an academic medical facility between January and April 2020 with a clinical diagnosis of chronic rhinosinusitis. Paranasal sinus axial and coronal computed tomography scans were evaluated for accessory maxillary sinus ostia in superior meatus and confirmed by reconstructed three-dimensional simulation images. The demographic information and incidence of accessory ostia in superior meatus were assessed. The Lund–Mackay score was used to rate chronic rhinosinusitis severity. Analysis of variance was performed to correlate the severity of chronic rhinosinusitis with presenting accessory ostia in superior meatus. Results: Of 159 patients (81 males; 78 females), 41.5% had accessory maxillary sinus ostia in superior meatus. Of these, two-thirds were bilateral and one-third was unilateral. The severity of rhinosinusitis was not correlated with having accessory maxillary sinus ostia in superior meatus, but the presence of accessory ostia was significantly associated with less severe chronic rhinosinusitis (P < 0.001). Conclusions: Accessory maxillary sinus ostia in superior meatus are significantly associated with less severe chronic rhinosinusitis and most cases are bilateral.

Paranasal Sinus Computed Tomography

We aimed to investigate the relationships among concha bullosa (CB), nasal septal deviation (NSD), and sinus disease. We retrospectively reviewed paranasal sinus computed tomography scans obtained from 296 patients—132 men and 164 women, aged 17 to 76 years (median: 39)—who had been evaluated over a 19-month period. CBs were classified as lamellar, bulbous, and extensive. In cases of bilateral CB, the larger side was designated as dominant. In all, 132 patients (44.6%) exhibited pneumatization of at least one concha, 176 (59.5%) had NSD, and 187 (63.2%) had sinus disease. Some 89 of 106 patients with unilateral or one-side-dominant CB (84.0%) had NSD, 89 of 132 patients with CB (67.4%) had sinus disease, and 109 of the 176 patients with NSD (61.9%) had sinus disease. We found a statistically significant relationship between CB and contralateral NSD, but no significant relationship between CB and sinus disease or NSD and sinus disease. While CB is a common anatomic problem that may accompany NSD, a causal relationship between CB or NSD and sinus disease is dubious.

Osteomeatal Complex

With the availability of high-resolution computed tomography (CT), a great deal of attention has been paid to the anatomy of the paranasal sinuses. But while investigators have focused on the osteomeatal complex and its relation to chronic rhinosinusitis, there has been little discussion of the superior turbinate. Although a few anatomic studies have tried to quantify pneumatization of the superior turbinate, the prevalence of this finding on radiography is not well addressed in the literature. We prospectively studied 100 consecutively presenting patients who underwent coronal CT of the paranasal sinuses (200 sides) for the evaluation of symptoms of chronic rhinosinusitis at an academic tertiary referral center to determine the prevalence of pneumatization of the superior turbinate. We found evidence of pneumatization in 44 of the 200 sides, for a prevalence of 22%. In all, pneumatized superior turbinates were found in 27 patients (27%)—bilaterally in 17 (17%) and unilaterally in 10 (10%).

Objective High-throughput DNA sequencing of the paranasal sinus microbiome has potential in the diagnosis and treatment of sinusitis. The objective of this study is to evaluate the use of high-throughput DNA sequencing to diagnose sinusitis of odontogenic origin. Study Design Case series with chart review. Setting Single tertiary care academic medical center. Subjects and Methods A chart review was performed of DNA sequencing results from the sinus aspirates obtained under endoscopic visualization in 142 patients with sinusitis. The identification of any potentially pathogenic bacteria associated with oral flora in a sample was classified as a positive result for sinusitis of odontogenic etiology. The sensitivity, specificity, and predictive values of using high-throughput DNA sequencing to diagnose sinusitis of odontogenic etiology were determined, with the patient’s computed tomography sinus scan as the reference standard. On computed tomography scans, an odontogenic source was determined by the presence of a periapical lucency perforating the schneiderian membrane. Results Seven of the 142 patients enrolled in this study had an odontogenic source based on computed tomography scans. Relative to this reference standard, high-throughput DNA sequencing produced a sensitivity of 85.7% (95% CI, 42.1%-99.6%), a specificity of 81.5% (95% CI, 73.9%-87.6%), a positive predictive value of 19.4% (95% CI, 13.1%-27.7%), and a negative predictive value of 99.1% (95% CI, 94.7%-99.9%). Conclusion This study supports the use of high-throughput DNA sequencing in supplementing other methods of investigation for identifying an odontogenic etiology of sinusitis.
