“…In our study 67.85% of scans were having single septum (47.87% complete and 20% incomplete) and multiple septum were present in rest of the scans (15.71% double septum and 16.42% triple septum). In previous studies, single septum was recorded from 61% to as high as 95% and multiple septa were cited between 7% to 95% scans [7,8,9,10] . In this study multiple septa are present in 45 cases (32.14%).…”

Sphenoid sinus is situated in midline within the sphenoid bone in the base of skull posterior to the ethmoid air cells. This sinus is in close proximity with optic nerve (ON), internal carotid artery (ICA), pitutary gland (PG) and cavernous sinus (CS). Sphenoid sinus approach is commonly used for endoscopic pituitary gland surgery and other skull base procedures too. Radiological evaluation of this sinus is of paramount importance before attempting any such surgical procedures. Aim: This study was designed to evaluate sphenoid sinus and surgical structures in sphenoid sinus region in Indian population with help of radiological imaging. Materials and Methods: Retrospective analysis of non contrast computed tomograms (NCCT) of 140 patients was performed. Parameters measured were type of pneumatisation, septa number and attachment, presence of lateral recess (LR) and carotico-optic sinus (COS), dehiscence of bony lamella and presence of onodi cell (OC). All scans were reviewed by a team of otorhinolaryngologist and radiologist. Results: The study group consist of 140 individuals (85 Males and 35 Females). The mean age of patients was 33.45 year for males and 37.36 year for females. Most common type of septa found was complete single septa and sellar pneumatisation, Lateral recess was present in 48.57% and Carotico-optic recess in 24.28% of cases; onodi cell was least frequently encountered in 5% of NCCT scans only. Conclusion: Variation are common in sphenoid sinus and pre operative radiological assessment of complex relations of sphenoid sinus septa with important structures present in vicinity of this sinus is of paramount importance before attempting any endoscopic surgery in this area.

“…The main septum it is located in the midline but usually deviated to one side, making an asymmetrical appearance of the sella turcica floor (20). We could also notice the presence of an incomplete septum in three cases (1, 3 and 4), this feature has a low prevalence published on literature (6,15). This characteristic could be explain in the fact of the Peruvian population is predominantly half blood, and there is not a specific patron.…”

El hueso esfenoidal ocupa la mayor parte de la zona anterior de la fosa craneal media, está compuesto por un cuerpo, dos pares de alas (mayores y menores) las que se proyectan lateralmente desde el cuerpo, y dos procesos pterigoideos proyectados inferior y lateralmente de las coanas. Este hueso representa el límite entre la fosa craneal anterior y media. Usualmente, el seno esfenoidal se encuentra ubicado en su cuerpo, el cual presenta una gran variación en su neumatización, variando desde ausente hasta extenso. Puede extenderse a distintas partes del hueso esfenoidal e inclusive a estructuras óseas cercanas. Su localización profunda hace difícil el diagnóstico mediante radiografías, especialmente cuando se utilizan técnicas convencionales. Se presentan cuatro casos de neumatización gigante del seno esfenoidal observados como hallazgo imagenológico.

“…Of particular note, among limited studies reported from India, Kirtane et al have evaluated the use of vidian neurectomy for crocodile tears, a sequelae lesion of the facial nerve. 24 Bhanu Pratap Singh et al, 25 Sushil Kumar Kashyap et al 26 and Prabu SS 27 have noted protruded and dehiscent vidian canal while studying variations in sphenoid sinus. They have not evaluated the degree of pterygoid process pneumatization.…”
