Frontal Cells: An Anatomic Study of These Cells With Consideration of Their Clinical Significance

Mapping the frontal sinus ostia using virtual endoscopy

“…T3 was found in almost half of our patients. This proportion is comparable to Van Alyea's finding of 63% of these cells being of the “invading” type 1. A third of our patients had blind recesses.…”

3D Computed Tomographic Analysis of Frontal Recess Anatomy in Patients Without Frontal Sinusitis

“…Such comparisons are limited by differences in technique (cadaveric dissection, CT scan parameters, computer-enabled CT review vs. review and films) as well as differences in terminology and definitions. The presence of ANC (89%), FBC (9%), and ISSC (14%) were consistent with the findings of Van Alyea (89%, 10%, and 12% respectively) 4,5 . Although the apparent prevalences of FBC are similar, Van Alyea used a different definition for FBC (as described above).…”

“…In the current report, the prevalence of SOEC was quite high (62%) as compared to Owen et al 10 (15%) or Van Alyea 4 (6%). In the current study, it became apparent that even moderately sized SOEC can recapitulate the appearance of the so-called “septate” frontal sinus.…”

A Study of Anatomy of Frontal Recess in Patients Suffering from ‘Chronic Frontal Sinus Disease’

“…In this study the prevalence of SOEC were 26 % as compared to that of 15 % in Owen and Khun's [1] study, 62 % in Lee et al [4] study and Van Alyea's [9] 6 %. Hence the prevalence of SOEC in our study falls within the range of the literature.…”
