Morphometry of frontal sinus in correlation to age and gender by computed tomography
IP Innovative Publication Pvt. Ltd, 2019
Introduction: The frontal sinus is funnel-shaped cavity separated by septum. The frontal sinus is unique to individual and often thought as a more symptomatic sinus because of the difficulties encountered in treatment of frontal rhino sinusitis. It requires the clinician to have precise knowledge of nasal sinus anatomy in the surgical treatment of sinusitis in recent years, particularly in endonasal endoscopic surgery. Materials and Methods: 100 patients (72 males and 28 females) undergoing coronal and axial sections of computed tomography scan of frontal sinus of head and neck aged between 1year to 90 years at the radiology department, Vydehi institute of medical science & research centre, Bangalore for reasons other than due to craniofacial abnormalities or sinus problem were taken for the study. Volume and dimensions of the frontal sinuses with its anatomical variations were obtained. Mean, SD, significant difference between age & gender was calculated. Results: Mean value of all the parameters of frontal sinus of both right & left were more in males compared to females. Compared between sides, all the parameters of both sides in males were more in right sinus than left side, in females right depth & volume were more on right side & height & width were more on left side. There is a significant difference in height of right frontal sinus, width & volume of left frontal sinus between male & female. The maximum height was observed in the age group in males on right side was in 51-60 yrs & on left side was 71-80yrs, in females on right & left side was 61-70 yrs. The Maximum width, depth & volume of sinus in males & females on right & left side were in age group 51-60 yrs. There is a significant difference both side in males & females and in right & left sinus in depth was in age group 11-20 yrs & on right side in 21-30 yrs age group. Conclusion: These results will be helpful in understanding normal and pathological conditions of the frontal sinuses & useful in clinical planning of medical or surgical interventions of the frontal sinuses.

Background There are considerable variations in the shape, capacity, and symmetry of the frontal sinuses. Hence, knowledge of frontal sinus anatomy and its variations is important for the diagnosis of sinus pathologies and prior to relevant surgical procedures. Objectives This study was undertaken to determine the presence of the anatomical variations and morphological characteristics of the frontal sinuses in a population aged between (20-85) years in Sulaimani city. Methods A review the CT scans of paranasal sinuses, which were taken in axial and coronal sections, of 100 individuals (58 males and 42 females), in the radiology department Sulaimani Teaching Hospital between April 1 st 2009 to June 30 th 2009. Results All measurements tended to be larger on the left side and were significantly larger in males than females. There was a significant difference in the anteroposterior dimensions of right and left sides in both sexes. Conclusion Morphometric features differed significantly in the two sexes at different ages and comparison with previous studies presented great regional variability.
CT study on morphometry of frontal sinus
Clinical Anatomy, 2008
The aim of this study was to determine the prevalence and morphological characteristics of the frontal sinus in an adult population. This study was conducted retrospectively on paranasal CT scans in the axial and coronal planes of 300 cases (123 male and 177 female). The mean age was 40.74 ± 13.34 (range 20–83). Measurements of the width, height and anteroposterior length for each sinus and total width were obtained from CT scans. Measurements were compared statistically with relation to side and sex. The cases were divided into subgroups according to age for each sex and each measurement parameter was also compared among the subgroups. All measurements tended to be larger on the left side and were significantly larger in males than females. There was a significant difference in the anteroposterior lengths of right and left sides in both males and females and height for males and width for females. In both sexes, the highest values of measurements were usually observed at the 31–40 age group and there was a tendency to decrease with aging. The larger diameters of the left frontal sinus imply that it may be more possibly violated during surgical interventions. Morphometric features differed significantly in the two sexes at different ages and comparison with previous studies presented great regional variability. The size of the frontal sinus was seen to be related to age and sex. The knowledge provided in the present study is useful for some surgical procedures and widens the anthropometric knowledge of humanity. Clin. Anat. 21:287–293, 2008. © 2008 Wiley-Liss, Inc.

Configuration of frontal sinuses A forensic prespective
Background: Identification of an individual whether living or deceased is of paramount importance in maintaining the integrity of the society. A simple, reliable, and efficacious method always finds a way for easier acceptance and inclusion in any discipline. Likewise, identification of an individual using the radiographic frontal sinus patterns is a simple technique which emphasized to conduct the study with a proven result. Objective: The objective of the study is to evaluate the radiographic configurations of frontal sinuses for their uniqueness based on different parameters. Study Group and Methods: Study group consisted of thirty individuals (15 males and 15 females) of age between 20 and 30. Individuals with the history of sinusitis, surgery, or any trauma were not included in the study. Paranasal sinus views were taken using standard exposure parameters, and the radiographs were assessed for their uniqueness. Results: The radiographs were assessed for area size, area asymmetry, superiority of the upper border, outline of the upper border, presence or absence of partial septa and supraorbital cells, and based on these results, a unique code number was assigned to each individual to prove the uniqueness. Conclusion: A frontal sinus comparison is particularly useful when no other means of an individual identification are available. Caution must be taken regarding the physiological and pathological changes (trauma, infection, old age, surgery, etc.) and postmortem changes and about the technical issues while taking a radiograph (distance, angle, orientation of the skull). In spite of all these issues, the configuration of frontal sinus is an excellent individualizing feature.

Background: Frontal sinuses are pneumatic cavities that radiologically revealed in 5 or 6 years old and completed in 20 years old. Comparison of the frontal sinus has significant value to establish identification. The purpose of this study was to comparison of frontal sinus and assessment of right and left frontal sinus volume according to gender by using Multi Detector CT scan (MDCT). With this background, this study was undertaken to examine and classify variations in frontal sinus and assessment of right and left frontal sinus volume according to sex by using CT scan. Materials and Methods: Sixty five consecutive men's and women's patients who underwent paranasal CT scans from September 2014 to April 2016 were identified from our institutional imaging database. Height, depth, and width of frontal sinuses were measured and a cubical approximation of volume determined by using Digimizer Image Analyzer. Result: Right and left frontal sinus were observed in 44 individuals (67.8%). Right frontal sinus was absent in 6 individuals (9.2%) and left frontal sinus was absent in 3 individuals (4.6%). Both of frontal sinus were absent in 9 individuals (13.8%). Right and left frontal sinus were not separate (integration) in 3 individuals (4.6%). Lack of frontal sinus frequency was higher in men and sinus integration was seen only in women .The average volume in left sinus was significantly higher than the right (P=0.02). Average volume of both the right (P=0.04) and the left (P=0.02) frontal sinus in males were significantly more than females. Conclusion: We found that the frontal sinus patterns had considerable individual variation. Right and left frontal sinus volumes were variable according to gender by using CT scan.

Human identification is considered as an important step in the reconstruction of biological profiles, especially of unknown individuals. Frontal sinuses (FS) have been regarded as an ideal anatomical structure for individualisation because few pathological conditions can potentially alter their shape. Aim: The aim of this review was to evaluate scientific evidence published since January 2010 and determine whether the dimensions and volume of FS might be useful parameters for gender determination and human identification, based only on cone beam computed tomography images (CBCT). Methods: This review was performed in accordance with the PRISMA statement. Four databases were searched for articles published between January 2010 and June 2022. Results: A total of 195 records were initially identified, and 90 remained after a manual duplicate check. Eight articles were selected for a full review according to the inclusion and exclusion criteria after title and abstract screening. A tota...
