“…The anatomical position of the sphenoid sinus is considered special in view of its proximity to vital anatomical structures, such as the internal carotid artery, sella turcica, pituitary, optic nerve, sinus cavernosus, visual cross and the third to the sixth cranial nerve (13)(14)(15). This poses a challenge for the clinical diagnosis and treatment of sphenoidal disease.…”

Expanding bilateral sphenoid sinus plasty is an essential technique for the treatment of sphenoid sinus diseases, such as refractory sphenoid sinusitis, sphenoid sinus cyst, fungal sphenoid sinusitis, sphenoid sinus carcinoma and sphenoid sinus chordoma. The present study evaluated the potential application of expanding bilateral sphenoid sinus plasty in the treatment of sphenoid sinus diseases. A retrospective medical record review of 42 patients treated with the expanding bilateral sphenoid sinus plasty from December 2012 to December 2018 was performed in a tertiary-care university hospital. A follow-up of the surgical effects and complications was performed. Of the 42 patients, the symptoms were relieved after operation in all except preoperative hyposmia in 2 and impaired vision in one with no obvious improvement. No complications such as nasal bleeding, olfactory hypofunction and perforation of nasal septum occurred. Follow-up data revealed good mucosal epithelization in all patients within a mean time of 8.6 weeks. Endoscopic sinus reexamination demonstrated that the sphenoid sinus orifice was well opened, and no cases of sphenoid sinus orifice closure were observed. Expanding bilateral sphenoid sinus plasty, with advantages of clearly exposed surgical field, full opening of the sinus cavity, high surgical safety, short epithelialization time and intuitionistic postoperative follow-up, demonstrated great promise for greater use in the treatment of sphenoid sinus diseases in the future.

Background The expanding bilateral sphenoid sinus plasty is an essential technique in the treatment of refractory sphenoid sinusitis. The aim of the present study was to explore the application of expanding bilateral sphenoid sinus plasty in the treatment of refractory sphenoid sinusitis. Methods Retrospective medical record review in a tertiary-care university hospital of 15 patients treated with the expanding bilateral sphenoid sinus plasty between December 2012 and December 2020. A follow-up of the surgical effect and complications were conducted. Primary outcomes evaluated were overall and disease-free survival. The end points assessed were presence of positive surgical margins, development of local, and regional recurrences. Results The patients were followed up for 12–73 months, with an average follow-up time of 28.5 ± 9.6 months. 15 cases of refractory sphenoid sinusitis were cured with well opened sphenoid sinus orifice and clean cavity. Of all the 15 cases, the symptoms were relieved after operation except preoperative hyposmia in 2 and impaired vision in one with no obvious improvement. No complications such as nasal bleeding, olfactory hypofunction and perforation of nasal septum occurred. Follow up revealed a better mucosal epithelization in all the patients within an average time of 8.6 weeks. Endoscopic sinus reexamination showed that the sphenoid sinus orifice was well opened, and no case of sphenoid sinus orifice closure was observed. Conclusion This study is a case series of a long time follow-up of the expanding bilateral sphenoid sinus plasty application in the treatment of refractory sphenoid sinusitis. With the advantages of easily intraoperative positioning, clearly exposed surgical field, full opening of sinus cavity, high surgical safety, short epithelialization time and intuitionistic postoperative follow-up, the expanding bilateral sphenoid sinus plasty is an improved way of treating refractory sphenoid sinusitis. Implications: This technique is worth being explored by surgeons for better surgical outcome.

“…They concluded that a 3D image of the sphenoidal anatomy allowed them performing bigger sellar openings and achieving a higher number of complete tumor removals in a safer way. 8,12,13 We propose the free available software named OSIRIX for the reconstruction of the images and realization of the virtual endoscopy as a reliable alternative to the dedicated software and systems made for that purpose. OSIRIX is an opensource DICOM viewer with the powerful capability of 3D volumetric rendering.…”

Background A preoperative three-dimensional (3D) surgical field understanding remains a key factor to achieve safer endonasal transsphenoidal endoscopic approaches (ETSE). The aim of this article is to describe how we can get a reliable 3D sphenoidal anatomical reconstruction for surgical planning by using a user-friendly, accurate, and free image software. Methods and Materials Free computer software (OSIRIX Medical Imaging Software) was used to create in a personal computer a three-dimensional (3D) reconstruction of the sphenoid sinus (SS) based on head computed tomography angiographies (CTAs) from a series of 67 patients who were operated for sellar tumors during a 4-year period (March 2016 to March 2020). The aim of the 3D reconstruction with OSIRIX was to reveal preoperatively the most important intrasphenoidal structures seen from the endonasal point of view. Results The intraoperative visible sphenoidal structures were previously recognized in the virtual 3D reconstructed image with 100% of specificity (SP) and positive predictive value. The OSIRIX view by using region of interest points allowed us to see preoperatively the internal carotid artery parasellar course even in those cases in which it was hidden by bone or tumor. Moreover, the 3D reconstruction was able to provide a clear differentiation between the tumor and the pituitary gland when both structures were in contact with the sellar floor. Conclusion Our experience with the OSIRIX software from CTA as preoperative planning for endonasal pituitary surgery was valuable, because it gave us access in simple way to a free and reliable 3D image of the SS.
