Paranasal Sinus Computed Tomography

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.

Objective: Diagnosis of a distal end radius fracture relies on various imaging studies. However, the relative usefulness of these studies is still a matter of some controversy. The aim of this study was to compare the intra-observer and inter-observer reliability of plain radiographs, standard computed tomography (CT) scans and mobile CT scans in the assessment of distal radius fractures as categorized by the Fernandez classification method. The secondary objective was to compare the dosages of radiation between the different imaging modalities. Material and Methods: Sixteen fresh cadaveric wrist bones were used in this experimental study. The desired fractures were created in the bones to mimic Fernandez types I-V fractures and plain radiographs were taken in 4 views. Standard CT and mobile CT scans were also taken with the fractured bones in the same four positions. Interobserver reliability was assessed using Kappa statistics to determine the diagnostic consistency among the nine observers. Inter-observer agreement was assessed based on the Fernandez classification system diagnoses. Results: Overall, the inter-observer agreement was substantial for the Fernandez classifications (Kappa range 0.636 0.727) in all types of imaging. For intra-observer agreement, the analysis found higher agreement for both standard CT scans and mobile CT scans. The standard CT images imparted a higher average dose of radiation than both the mobile CT scans and the plain radiographs.Conclusion: The mobile CT scan can provide an alternative imaging method for precise diagnosis of distal end radius fractures, with the additional benefits of mobility and lower radiation exposure.

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.
