ANALYSIS OF FRONTAL CELLS ACCORDING TO INTERNATIONAL FRONTAL SINUS ANATOMY CLASSIFICATION IN PATIENTS WITH CHRONIC RHINOSINUSITIS
1Sağlık Bilimleri Üniversitesi, İzmir Bozyaka Eğitim ve Araştırma Hastanesi, Kulak Burun Boğaz Kliniği, İzmir, Türkiye Objective: The goal of this study was to evaluate the prevelance of frontal cells (according to International Frontal Sinus Anatomy Classification) in patients with chronic rhinosinusitis (CrRNS) and to compare them with the control group and assess the association with frontal sinusitis.Methods: The patients who were treated with the diagnosis of CrRNS between January 2014 and March 2019 and underwent high resolution paranasal sinus computed tomography (PNSCT) were included in the study. The subjects without sinonasal disease who had other indications (chronic dacryocystitis, headache etc.) for PNSCT were determined as control group.
Results: 62 patients (124 sides) with CrRNS and 65 patients (130 sides) in the control group were included in the study. Supra-bullar cells (SBC), supra-bullar frontal cells (SBFC) and frontal septal cells (FSC) were significantly more frequent in patients with CrRNS than the control subjects (p=0.002, p<0.0001, p=0.001, respectively). The presences of SBC, SBFC and FSC were significantly correlated positively with the incidence and severity of frontal sinusitis.
Conclusion: It should be kept in mind that cells such as SBC, SBFC and FSC may play a role in the development of frontal sinusitis. These cells may need to be considered in the treatment plan in order to increase the success rate of surgical treatment.
