Purpose. Refinement and addition of a computed tomography protocol to improve diagnostic accuracy in paranasal sinus examination.
Materials and methods. A total of 520 patients (100%) with a referral diagnosis of rhinosinusitis were examined in the clinic of the National Medical Research Centre for Otorhinolaryngology FMBA. All patients underwent computed tomography of paranasal sinuses (PNS). In the course of the work, a refined protocol was developed, including a detailed description of all anatomical structures.
Results. Analysis of CT studies of 417 patients revealed significant correlations between the anatomical features of the paranasal sinuses and the development of inflammatory diseases, which necessitated a detailed diagnosis of the condition and anatomy of the PNS. Deviation of the nasal septum appeared to be a key factor in the development of pansinusitis. Frontal sinusitis is closely related to structures affecting the fronto-nasal canal (agger nasi, bulla frontalis), ethmoiditis – to factors narrowing the middle nasal passage (concha bullosa), sphenoiditis – to the Onodi cell, and maxillary sinusitis – to the Haller cell and the accessory junction. The identified correlations highlight the importance of anatomical variants in the pathogenesis of sinusitis and can be used to optimize diagnosis and treatment.
Discussion. Computed tomography (CT) is a highly informative method for the evaluation of the PNS due to its high resolution, allowing detailed visualization of its structure. An advanced CT protocol that takes into account the anatomical features of the patient's area provides an accurate description of variations in the structure of the paranasal sinuses (PNS), which significantly improves the quality of diagnosis and treatment of PNS diseases.
Conclusion. The developed extended protocol of CT description of paranasal sinuses allows to optimize the assessment of paranasal sinuses in patients with rhinosinusitis, which is important in the choice of treatment tactics in these patients.
