Evaluation of Anatomical Variations of Paranasal Sinuses Using Cone Beam Computed Tomography - A Retrospective Study.
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2019, Vol 4, Issue 6
Abstract
Aim: The aim of this study is to evaluate anatomical variations of nasal cavity and paranasal sinuses the incidence of Onodi cells, Agger Nasi Cells, Kuhn Cells And Haller Cells and to determine the relationship of these variations with age, side and gender of an individual. using cone beam computed tomography (CBCT), which is currently used in dental radiology. Objectives: To evaluate the frequency and relationship of these variants to age and sex.To facilitate surgical planning in patients undergoing endonasal procedure.To aid in diagnosis of facial pain and headache. Material And Methods: This retrospective study consists of 100 Adult CBCT images of 50 males and 50 females, who were listed for Implant retained Prosthesis and temperomandibular joint disorder. Radiographic assessment of paranasal sinuses including aggernasi cells, Kuhn cells, ondoi cells and haller cells were accurately characterized using customized planmeca romexis software. Age group of 18-60 years were included and Images with gross artifacts, images of trauma and nasal surgery were excluded. Result: This study showed highly significant results in prevalence of different type of cells. There is no correlation between age and gender. Conclusion: Different anatomical variants may often be found in paranasal sinus region and CBCT imaging is the modality of choice to evaluate these variants since conventional radiographs do not provide adequate information because of structural superimposition. These variants may determinate contact points between nasal structures stimulating “trigger” points and determining facial pain crisis. Identification of these variants plays an important role while guiding the surgeons preoperatively and preventing iatrogenic complications.
