Is there a relationship between sphenoid sinus types, septation and symmetry; and septal deviation?

Abstract

In the present study, we investigated whether there is a relationship between sphenoid sinus (SS) types, septation (lobulation) and symmetry; and septal deviation (SD) by multidetector computed tomography (MDCT). Paranasal MDCT images of 202 subjects (131 males, 71 females), between 10- and 88-year-old, were included into the study. SS type (conchal, presellar or sellar), SS symmetry, SS septation (lobulation) and SD were evaluated by MDCT images. In the present study, in both males (83.2 %) and females (85.9 %); and in all age groups (80.4-85.7 %), sellar type sphenoid sinus were more detected. Conchal type was detected in two cases of the males (1.5 %) and none of the females. SS was detected mainly as multi-septated (multi-lobulated) (51.9 % in males and 56.3 % in females; in all age groups as 51.0-56.8 %; and both SD (+) and SD (-) groups as 51.2-56.8 %). In subjects with SD, asymmetric SS was detected in 80.2 %. Whereas in SD (-) subjects, asymmetric SS was detected in 50.6 %. Sellar type SS pneumatization is the most detected type in our cases. Presence of SD was related to the higher SS asymmetry values. In SD (-) subjects, SS was detected as symmetric. Nasal septal deformities such as SD may influence the development of the SS pneumatization and asymmetric septation. For well anatomic orientation of the surgeons, good anatomy knowledge and preoperative detailed examination of the CT scans are very important.

Risky anatomical variations of sphenoid sinus and surrounding structures in endoscopic sinus surgery

“…Poirier et al [ 27 ] reported attachment of the IS onto the ICA in 3.4%, Batra et al [ 28 ] in 37.5% and Dziedzic et al [ 26 ] in 49% of cases. In our work, we identified that 30.4% presented AS similar to levels reported by Anusha et al [ 16 ] Jaworek-Troc et al [ 29 ] reported that AS were present in 78.0% of cases, similar to levels reported by Akgül et al [ 17 ]. Aksoy et al [ 25 ] reported that AS originated in the ICA protuberance in 47.7% of cases while they were associated with the ONC protuberance in 17.5%, comparable to our data.…”

“…In previous literature, the sellar type is reported in very high percentages ranging between 78.5 and 93% [ 16 – 19 ]. In our study, the conchal type was detected in 8.5% of cases, greater than reported in the literature (1–2%) [ 17 – 19 ]. No conchal type was detected by Wang et al [ 20 ], Dal Secchi et al [ 15 ], or Anusha et al [ 21 ].…”

Evaluation of Relationship Between Sphenoid Sinus Septation and Onodi Cells Using Cone-Beam Computed Tomography

“…Although this rate was seen as 38%, 21 29.6%, 22 28.1%, 23 and 20% 24 in some studies, the incidence in our study was 8.8% and it was much lower than in others. When the intersphenoid sinus septation was evaluated according to gender, Kapur et al 25 found that this parameter was 68% and 77.9% in males and females, respectively, and Akgül et al 26 detected this rate as 48.1% and 43.7%, respectively. In the present study, intersphenoid sinus septa were found as 10.8% in males and 6.8% in females.…”

Pediatric paranasal sinuses—Development, growth, pathology, & functional endoscopic sinus surgery

“…Ethmoidal cell volume on the ipsilateral side has been shown to decrease with increasing severity of deviation (Bayrak et al, 2018; Firat et al, 2006). No difference in frontal sinus volume in individuals with NSD regardless of the degree of deviation has been reported and although higher rates of sphenoid sinus asymmetry has been reported in individuals with NSD (80.2% vs. 50.6%) differences in volume have not been quantified (Akgul et al, 2016; Bayrak et al, 2018; Karatas et al, 2015. Overall, the effects of NSD on paranasal sinus development have not been demonstrated in children however adult studies suggest that the impact on sinus growth may become increasingly apparent with age, especially in cases of severe septal deviation.…”

“…The majority of growth has occurred by 14–16 years of age (Barghouth et al, 2002; Hinck & Hopkins, 1960; Karakas & Kavakli, 2005; Park et al, 2010; Rennie et al, 2017b; Sánchez Fernández et al, 2000; Spaeth et al, 1997; Yonetsu et al, 2000). Left–right asymmetry is common however there is no clear consensus regrading which side is larger (Adibelli et al, 2011; Akgul et al, 2016; Barghouth et al, 2002; Chang et al, 2014; Dixon, 1937; Park et al, 2010; Sánchez Fernández et al, 2000; Schaeffer, 1936; Spaeth et al, 1997). There is no clear agreement regarding if sexual dimorphism exists in SS size either with some papers demonstrating larger sinuses in males while others have shown no difference (Adibelli et al, 2011; Barghouth et al, 2002; Emirzeoglu et al, 2007; Idowu et al, 2009; Karakas & Kavakli, 2005; Park et al, 2010; Sánchez Fernández et al, 2000; Spaeth et al, 1997; Vidić, 1968; Yonetsu et al, 2000).…”
