“…In their study, MTP rate was 44.2%; 30.0% in FS type I, 40.0% in type II, and 62.5% in type III, significantly higher in type III. Unlike our study, Yazici 4) showed significant differences in MTP rate; this is probably because their study targeted Turkish and our study Koreans. That is, it may have been caused by racial and geographical differences.…”

“…There is limited literature between the relation of the degree of FS pneumatization and the development of the PNS structures. [1][2][3][4] Lateral lamella length (LLL) and olfactory fossa depth are important anatomical parameters to be considered in preventing surgical complications like skull base injury. Greater LLL increases the possibility of lateral lamella injury during the surgery.…”

Background and Objectives It is necessary to understand the variations of the paranasal sinuses (PNS) and other anatomical structures during an endoscopic sinus surgery (ESS). The purpose of this study was to investigate any association between the degree of frontal sinus (FS) pneumatization and the development of the PNS structures. Subjects and Method We analyzed 311 PNS computed tomography (CT) scans (622 sinuses, including the left and right sides). We classified FS into type I (aplasia), type II (hypoplasia), and type III (control). We assessed and compared the middle turbinate pneumatization (MTP), superior turbinate pneumatization (STP), agger nasi cell (ANC), infraorbital cell (IOC), optic nerve (ON) type, and vidian nerve (VN) type with the pneumatization of the FS. We further studied for any association between the degree of pneumatization of the FS, maxillary sinus (MS), and sphenoid sinus (SS) and the lateral lamella length (LLL). Results MTP, ANC, and IOC rates according to the FS types were not significant (p>0.05). Both type II and III showed more frequent occurrences of STP than type I (p=0.005). The ON type III and IV were significantly frequent in the FS type III (p<0.001). The occurrence of VN type III in the FS type I was significant (p<0.001). When comparing the pneumatizations of FS with MS or SS, there were no significant correlations between them (p>0.05). In the FS type II and III, the LLL was significantly greater than in type I (p<0.001). Conclusion Increased FS pneumatization shows greater indentation of ON and VN into the SS, as well as increased LLL. During ESS, it is important to recognize the possibility of structural damage of ON, VN, and LLL according to FS pneumatization.

“…The two frontal air sinuses acquire pneumatization at a variable pattern and it is independent. 32 In the current research, the mean value for the right frontal air sinus area in the different male ethnic groups showed significant variations. Dissimilarities were also observed when the left frontal air sinuses areas were compared among the four ethnic groups.…”

Objectives: To determine anatomical variability in morphometry of frontal air sinuses in male ethnic groups residing in Karachi. Study Design: Cross sectional descriptive study. Setting: Radiology Department of Jinnah Postgraduate Medical Center. Period: Nov 2018 to April 2019. Material & Methods: In total, the research subjects were 108. They were divided into four ethnic sub groups. Each ethnic subgroup had 27 members. The study subjects were in between 20 to 50 years of age with the mean age of 35.14 ± 8.68 years. Before the enrolment of the participants in the research, informed consent was taken. The methodology incorporated was X-ray radiography. The view for radiology was Water’s view. Area, height and width of both right and left frontal sinuses were measured by the help of Radiant DICOM digital software. A questionnaire was designed to record the demographic data. The parameters of area, height and width of the sinuses were noted in the proforma. The data was analyzed by the help of SPSS version 23.0. Results: The ethnic sub groups were compared by the application of One Way ANOVA. The comparison of the four ethnic groups showed high variability in terms of area, height and width of the right frontal air sinuses (p=0.000). Significant variations were also recorded for these parameters on the left side (p=0.000). Conclusion: The height width and area show pattern of anatomical variability in the right and left frontal air sinuses among the ethnic groups of males living in Karachi.

Introduction: Spontaneous cerebrospinal fluid rhinorrhea (SCSFR) is the most common type of cerebrospinal fluid leakage and may cause serious cerebral complications. The aim of this research was to investigate the relationship between the degree of pneumatization variants of the paranasal sinus and skull base and the incidence of SCSFR. Methods: In total, 131 patients with SCSFR were analyzed, and 50 patients suffering from the nasal septal deviation were selected as controls. The pneumatization of the paranasal sinus and skull base was observed by CT scan. Results: Among the 137 fistulas, 55 (40.15%) were found in the ethmoid sinus. The incidences of Onodi cells (27.27 vs. 8%) and type 3 lateral recess of the sphenoid sinus (LRSS, 70.37 vs. 22%) in the SCSFR subgroups were significantly higher than those in the control group (p < 0.05). Moreover, the occurrence of SCSFR was linearly correlated with the classification of Onodi cells and LRSS (p < 0.05). There was no significant difference in the incidence of frontal cells, anterior clinoid process pneumatization, and posterior clinoid process pneumatization between the SCSFR patients and the controls. Conclusion: The most common site of SCSFR is the ethmoid sinus. The excessive pneumatization of the Onodi cell and LRSS increases the risk for the occurrence of SCSFR in the ethmoid sinus and sphenoid sinus, respectively. The possible association between the paranasal sinus ontogeny and SCSFR pathophysiology needs further studies.
