The effect of frontal sinus pneumatization on anatomic variants of paranasal sinuses

Abstract

Purpose

The aim of this study is to determine the effect of frontal sinus pneumatization on various variations of paranasal sinuses on maxillofacial CT.

Materials and methods

A total number of 120 patients (62 females, 58 males) were included in this study. Patients were divided into three groups regarding their frontal sinus pneumatization extent on paranasal sinus CT as Type 1 pneumatization (aplasia and hypoplasia), Type 2 pneumatization (medium) and Type 3 pneumatization (hyperplasia). The prevalence of various variations on paranasal sinus CT like pneumatization of upper and middle concha, presence of agger nasi, Haller and Onodi cell, maxillary sinus and sphenoid sinus hypoplasia, pneumatization of anterior clinoid process, pterygoid process and greater wing of sphenoid sinus, dehiscence and protrusion of internal carotid artery and optic nerve and vidian canal types were ascertained and compared within each group.

Results

The prevalence of upper and middle concha pneumatization, Haller cell, pneumatization of anterior clinoid process, pterygoid process and greater wing of sphenoid and internal carotid artery dehiscence and protrusion was higher in Type 3 group compared with other groups.

Conclusion

Excessive pneumatization of frontal sinus has various effects on paranasal sinus variations at maxillofacial CT. Surgeons dealing with endoscopic sinus surgery, maxillofacial and skull base surgery must be vigilant of association between certain variations when analyzing CT scan preoperatively for avoiding complications.
