Anatomical Variations of the Frontal Sinus

Abstract

PONDÉ, J. M.; ANDRADE, R. N.; VIA, J. M.; METZGER, P. & TELES, A. C. Anatomical variations of the frontal sinus. Int. J. Morphol., 26(4):803-808, 2008.SUMMARY: An anatomical study of the frontal sinus in 100 macerated skulls. The study introduces an innovation on the literature by means of the measurement of the sinus's volume. All the found information in the literature attained to other aspects including the diameters of the sinus and the geometric area of the same. Objective: Evaluation of the measures of the frontal sinus frequently involved in cranial base surgeries and supraorbital craniotomies in order to help the surgical approaches that cross this anatomical route Methods: The measurement included: sagital, transverse and antero-posterior diameter acquired with a paquimeter and the volume obtained after filling the sinus with sand. Results: They are in accordance with the literature that shows the male's predominance in all measurements done.

Morphometric Sexual Dimorphism of Frontal Air Sinus: ACT Study

“…Our study, correlates with the study of Tatlisumak E, et al [10] (2008) & Mathew KL, et al [11] (2010) in case of AP diameter, but not in Height & Width where there is significant male -female difference, that too male having higher values.In the present study, Volume of frontal sinus when compared between male and female, the readings of males are towards higher side as compared to females but, it is not significant. This correlates with Ponde JM, et al [12] (2008). Whereas, Sacide K, et al [13] (2005) got significant relation; that too more in males as compared to females.…”

Association between frontal sinus development and persistent metopic suture

“…One is developed from the expansion of the ethmoid sinus into the frontal bone, and other is developed from an independent invagination of the middle meatus of the nasal passage; they never coalesce [25]. As the growth of the inner table ceases at the age of 6-7 when the frontal lobes have reached Moreover, in many studies the absence of frontal sinuses was found at rates changing from 5% to 27.9% regardless of persistence of the metopic suture [12,15,22].…”

<i>Unleash the Unknown - </i>Frontal Sinus and Nasal Septal Patterns in Personal Identification

“…Previous studies had disclosed that the frontal sinuses were found to be different for every individual even in case of monozygotic twins and dizygotic twins and implicit that they have individual morphological variations [3,5,7,9]. Configuration of frontal sinus is also said to be controlled by various environmental factors, although gender, race, and disease are known to affect its development [13,14,15]. On the other hand, nasal septal patterns also holds similar unique findings as does the frontal sinuses [13,14,15].…”
