“…Among paranasal sinuses, the frontal sinuses are the last to complete development (de Oliveira et al, 2013). At birth, the frontal sinuses are not yet developed or are absent, but are generally fairly well developed between the 7th and 8th years, only reaching their full size after puberty (Scuderi et al, 1993;Standring).…”

SUMMARY:The sinonasal region in humans is one of the regions that commonly shows anatomical variations. These variations can be easily diagnosed by paranasal CT evaluation. One of these variations is Crista galli pneumatization. In recent years, there have been opinions supporting the hypothesis that pneumatization originates from the frontal sinus. In this study, we planned to evaluate whether the presence of Crista galli pneumatization varied in pre-adult and adult periods. In this retrospectively designed study, 218 coronal paranasal CT images collected between 2012 and 2013 were evaluated. Patients were divided into two groups according to age under or over 18 years. In the group under the age of 18 (97 cases), pneumatization was detected in 2.1 % of samples, while in the group over the age of 18 (121 cases), crista galli pneumatization was observed in 15.7 % of samples. According to these results, crista galli pneumatization was found to increase in adulthood. Considering that the frontal sinus is in a rudimentary state at birth, it is radiographically detected first at 6 years of age, and reaches its main size in puberty, this increase in pneumatization runs parallel to the development of the frontal sinus. Consequently, this supports the opinion that crista galli pneumatization originates from the frontal sinus.

“…Posterior extension of the frontal sinus into the orbital roof has been reported in 2 out of 18 cadaveric dissections with & H. Wechalekar harsha.wechalekar@unisa.edu.au a complete aplasia in one of the specimens [24]. A recent study has shown extensive supraorbital extension of frontal sinus in CT scans of an asymptomatic 86-year-old female patient with an accompanying enlargement of sphenoidal and maxillary sinuses [9]. However, extension of frontal sinus into the roof of the optic canal is not known.…”

This case reports a bilateral asymmetrical posterior extension of the frontal sinuses into the orbital roof with an unusual expansion into the roof of the optic canal in a 55-year-old male cadaver. The posterior extensions of the sinus were lined by mucoperiosteum and were separated from the underlying orbital contents and optic nerve by a thin plate of bone. This knowledge of an unusual anatomic variation of the frontal sinus may help understand better the ocular and intracranial complications associated with frontal sinus pathologies.

“…The sinonasal cavities, presented by the ostiomeatal complex and paranasal sinuses, are the vital parts of the upper respiratory tract (1). Ostiomeatal complex is a functional unit which is a limited anatomical region consisting of: middle turbinate, uncinate process, bulla ethmoidalis as bony structures; frontal recess, ethmoidal infundibulum, middle meatus as air spaces; and anterior ethmoidal, maxillary and frontal sinuses as ostia.…”

Objectives: The paranasal sinuses include anatomic structures at the maxillofacial region that matters great importance for the surgeons working in the maxillofacial area. The imaging of anatomic variations of the paranasal sinuses is fundamental to evaluate the predisposing factors for the pathologic changes of paranasal sinuses. The aim of this study is to investigate the prevalence of anatomic variations of the paranasal sinuses by retrospective assessment of cone beam computed tomography (CBCT) images. Methods: The paranasal sinus CBCT images of 300 adult patients who were referred to Marmara University, Faculty of Dentistry, Department of Oral Diagnosis and Radiology were evaluated retrospectively. The paranasal sinus variations and their prevalence were recorded. Results: The prevalence of concha bullosa superior was 7,7%, and concha bullosa media was 54,7%. The prevalence of infraorbital ethmoid cell was 15,3%, agger nasi cell was 52,7% and onodi cell was 52.7%. There was no significant differences prevalence of this anatomic variations between males and females or between different age groups. Conclusions: CBCT is a convenient radiographic examination to evaluate the paranasal sinus anatomic variations. Dental surgeons must be aware of such anatomic variations of the paranasal sinuses.
