Multiplanar Computed Tomographic Analysis of the Frontal Recess Region in Chinese Subjects without Frontal Sinus Disease Symptoms

Agger nasi cells contribute to nasofrontal duct (NFD) obstruction and chronic frontal sinus disease. To investigate this relationship, we conducted a review of the surgical outcome and computed tomographic imaging in 26 patients with chronic frontal sinusitis. Coronal and sagittal images were used to delineate the anatomic variability and mucosal disease in the NFD and frontal sinus region. Data from coronal and sagittal images were compared. The results were also correlated with the outcome of frontal sinus surgery in patients with a clinical history of chronic frontal sinus disease. Our data suggest that agger nasi cell pneumatization with narrowing of the frontal sinus outflow tract is a significant cause of persistent frontoethmoid pain and chronic frontal sinusitis. Sagittal reformatted images are more capable than coronal images of demonstrating agger nasi cell encroachment on the NFD, as well as NFD mucosal disease. Endoscopic frontal sinusotomy is an effective treatment for chronic frontal sinus disease.

Background: The involvement of frontal cells in the frontal sinus disease pathology remains an understudied area. There are very few reports on the prevalence of frontal recess cells in India. In this context the present study was designed to determine the frequency of occurrence of Kuhn frontal cells and to determine whether the size of the frontal isthmus or the presence of frontal cells is related to the presence of frontal sinus disease.Methods: This study included 80 patients who presented with signs and symptoms of chronic rhino-sinusitis after satisfying the inclusion criteria to the Department of ENT in a tertiary care centre (Mahatma Gandhi Medical College and Research Institute) in Pondicherry from January 2017 to April 2018. The patients were subjected to detailed clinical history, basic preoperative blood investigations, diagnostic nasal endoscopy and High Resolution Computed Tomography of nose and para-nasal sinuses after which the diagnosis was established.Results: Out of the 80 study participants subjected to our study the number of individuals who had frontal sinusitis was 50%. The association between frontal sinusitis and Kuhn cells was insignificant. The mean value of anteroposterior diameter of the naso-frontal isthmus in case of patients with and without frontal sinusitis was 0.705-0.735. In case of transverse diameter it was 0.725-0.720 and in case of the area of the frontal isthmus it was 30.86-31.12 which had a p value of 0.49Conclusions: Therefore in our study we concluded that there is no significant relation for any particular frontal recess cell or the size of the nasofrontal isthmus for being the sole cause for chronic frontal sinusitis.

Chinese Subjects

Objectives The aim of this study is to look at the incidence of supraorbital ethmoid cells (SOEC) in normal Chinese subjects by using spiral computed tomography (CT) scanning. In addition, subjects with chronic rhinosinusitis with SOEC were reviewed for endoscopic analysis. Methods A total of 202 normal Chinese subjects underwent spiral CT. Meanwhile, a retrospective review of patients who had undergone endoscopic sinus surgery over a 1-year period was conducted. Results SOEC showed an incidence of 5.4% (22 sides), and all of them arose from the anterior ethmoid cells. On coronal CT, an SOEC might give the appearance of multiple frontal sinuses, type III frontal cells, suprabullar cells, frontal bullar cells, inter-frontal septal cells, or that there was a septation present within the frontal sinus. Meanwhile, 11 chronic rhinosinusitis patients with 12 SOEC were identified. Conclusion A thorough knowledge of endoscopic anatomy and CT of the frontal recess and various fronto-ethmoid cells were required for safe dissection of the SOEC and frontal ostium.
