Abstract

Objective:

To describe a newly observed frontal sinus anatomical variant, the fronto-septal rostrum.

Methods:

Consecutive sinus computed tomography scans performed during 2013 were reviewed. The fronto-septal rostrum was defined as a mucosa-lined air space formed in the attachment of the most upper bony nasal septum and the central floor of the frontal sinuses.

Results:

The study included 400 computed tomography scans from 189 women (47.3 per cent) and 211 men (52.8 per cent), with a mean age of 46.8 years. A fronto-septal rostrum was observed in 122 patients (30.5 per cent), with a mean length of 10.63 mm, width of 4.52 mm, height of 2.18 mm and volume of 63.52 mm3. There was no statistically significant difference related to gender (p = 0.343), and no association between the side of the fronto-septal rostrum and age (p = 0.811) or volume (p = 0.203).

Conclusion:

The newly described fronto-septal rostrum has possible clinical and surgical implications. It is suggested that this aerated space is used in specific surgical indications and its presence evaluated in cases of septal infection.
