Comparative Study between Microscopic and Endoscopic Trans-Sphenoidal Surgery for Growth Hormone-Secreting Pituitary Adenomas with Super-Sellar Extension

Background: Advances in the era of modern micro-neurosurgery enabled a reduction of surgical invasiveness and brain retraction which has been defined as minimally invasive or keyhole surgery. Sinonasal endoscopy has brought radical changes in the concepts of pathophysiology and treatment of sinonasal aliments as well as surgical techniques. Aim of the Study: To compare between the use of endoscopic and microscopic trans-sphenoidal approach in resection of growth hormone-secreting pituitary adenomas with Suprasellar Extension. Patients and Methods: This is a prospective study. It had been conducted upon 20 patients having growth hormone secreting pituitary adenoma admitted to Neurosurgery department in Alzar University hospitals and Nasr City Insurance hospital from 2015 to 2018, divided into 2 groups;group A (10 cases) underwent endoscopic endonasal trans-sphenoidal pituitary adenoma resection, while group B (10 cases) operated upon using the standard microscopic trans-sphenoidal pituitary adenoma resection. The inclusion criteria were included: All patients with growth hormone secreting pituitary adenomas showing manifestations of acromegaly, mass effect or hormonal disturbance. Results: This study showed that improvement in outcome was higher in endoscopic group opposed to microscopic group (100% vs. 71% improved headache, 80% vs. 60% visual improvement, 75% vs. 20% fundus improvement and 60% vs. 30% field improvement). Conclusion: We concluded that fully endoscopic procedure result in improved rates of complete tumor removal and a reduced incidence of complications, when compared to the microscopic approach.

Management of Sphenoidal Sinus Lesions by Septal-assisted Approach: Surgical Skills and Advantages

Summary： The aim of this study was to develop a less invasive trans-septal approach for the endo- scopic management of sphenoid sinus lesions. We performed a septal-assisted surgical procedure for endoscopic sphenoidectomy in 38 patients with isolated or combined sphenoidal sinus lesions, including fungal balls, mucoceles, purulent cystic sphenoidal sinusitis, etc. The posterior portion of the nasal sep- turn became flexible after removal of the vomer and the sphenoidal rostrum. The superior portion of the common meatus was expanded to accommodate the endoscope after the septum was repositioned con- tra-laterally. The lesions were individually managed through the enlarged ostiums while damage to the mucosa of the front sphenoidal wall was avoided. All the procedures were completed successfully without intraoperative complications, and the bony ostiums were identified easily and enlarged accu- rately. During the follow-up period of 16 weeks to 2 years, no re-atresia or restenosis was observed. The recurrence rate was 0. No postoperative complications were recorded. All the responses from the pa- tients were satisfactory. It was concluded that endoscopic sphenoidectomy assisted by trans-septal ap- proach is a feasible, safe, effective and minimally invasive approach for selected cases with unilateral or bilateral lesions in the sphenoid sinuses.

Study of the relationship between sphenoid sinus volume and protrusions in the sphenoid sinus

The relationship between the volume of sphenoid sinus (SS) and the prevalence of internal carotid artery (ICA) and optic nerve (ON) protrusions in the SS was studied by using high-resolution CT imaging. The ICA and ON protrusions in SS were observed in randomly selected normal head CT scanning images from 350 adult subjects. Ac-cording to the incidence of ICA protrusion, three groups were divided into no ICA protrusion (70.75%), unilateral protrusion (8.68%) and bi-lateral protrusions (20.57%). The ON protrusion accounted for 16% in 350 subjects and accom-panied absolutely with ICA protrusion, but ICA protrusion appeared without accompanying with ON protrusion. The SS volume depended upon the protrusions in it and showed statistical dif-ferences, without ICA protrusion, the smallest size (11.16 ± 1.60) cm3;the unilateral protrusion, medium size (14.20 ± 1.80) cm3 and the bilateral protrusion, the largest size (25.03 ± 2.21) cm3. By observing 3D reconstructed models of ON and SS, we found ON was adjacent to SS (46%) and to posterior ethmoid sinuses (44%). The current study indicates that SS volume is varied with numbers of the protrusions and that ON location varies with the pneumatization of SS. Our results provide an anatomical basis to the surgeries for SS and its surrounding structures.

Sphenoid Sinuses Pneumatization and Association with the Protrusion of Surrounding Neurovascular Structures amongst Beninese

Goal: The aim of this work is to study the relationship between the pneumatization of the adjacent structures of sphenoid sinuses and the protrusion of the neurovascular structures in the sinuses. Methods: A review of 225 CT scans skull was done for subjects aged at least 16 years old from November 1st to December 31st 2017. The pneumatization of adjacent structures of sphenoid sinuses and its relation with the protrusion of neurovascular structures surround the sinuses have been investigated. We used Fischer Exact test for comparison. The p value Results: Statistically significant associations were found between anterior clinoid process bilateral pneumatization and bilateral protrusion of carotid canal (p Conclusion: Compared to the literature, the prevalence of pneumatization of the adjacent structures of sphenoid sinuses was lower on Beninese than Caucasian and Asian. But there were the same correlations with the protrusion of neurovascular structures. In case of endonasal surgery of the sphenoid sinuses, surgeon should be aware of the high possibility the injury of optic nerves and internal carotid artery.

Anatomic Variants of Sphenoid Sinuses and Adjacent Structures: A Study of 225 Skull CT Scans at CNHU-HKM in Benin, West Africa

Objective: This study aimed to describe anatomic variants of sphenoidal sinuses and adjacent structures. Methods: A retrospective and descriptive study was carried out at The National and University Teaching Hospital Hubert Koutoukou Maga (CNHU-HKM), of Cotonou in Benin from November 1st to December 31st. A review of CT scans skull was done for the subjects aged at least 16 years old. Anatomic variants of the sphenoid sinuses and adjacent structures have been investigated. Results: 225 CT scans of skull were analyzed. The sellar type was the most common type of pneumatization of sphenoid sinuses (74.7%). Pneumatization of anterior clinoid processes of greater and lesser wings of the sphenoid and of pterygoid processes was observed in 7.1%;4.6%;3.3% and 7.3%;respectively. Protrusion of carotid canals and optic canals, maxillary and vidian nerves were observed in 48.3%;13.1%;18% and 9.5%;respectively. Conclusion: Risky anatomic variants of the sphenoid sinuses and adjacent structures are also described by CT-scan among Beninese. Before any surgery and to avoid bad outcome, a precise approach of these risky anatomic variants must be carried out by using CT-scan.

Treatment of Organized Hematoma of the Sphenoid Sinus with Pre-Operative Embolization and Endoscopic Resection

The differential diagnosis for expansile masses of the sphenoid sinuses includes both benign and malignant lesions. We herein present a case of a 79-year-old female who presented with chronic epistaxis and an expansile soft tissue mass centered in the sphenoid sinus with erosion of the skull base. Endoscopic resection of the lesion was performed, with histopathological examination revealing organized hematoma. To our knowl- edge, this is the first reported case of sphenoid sinus organizing hematoma treated with pre-operative embolization followed by endoscopic excision.

Incidental Discovery of Sphenoid Sinuses Agenesis: A Report of Two Cases in Benin, West Africa

Sphenoid sinuses are carved into the body of the sphenoid bone. They are probably the most variably pneumatized structures of the skull. They begin their pneumatization at the age of three and finished at adolescence. Several anatomic variants of sphenoid sinuses have been described in the literature. The agenesis of sphenoid sinuses in adults is very rarely found. We report two incidental cases of sphenoid sinuses agenesis discovered on CT scan in Benin, West Africa.

Application and Care of Two Kinds of Sphenoid Sinus Packing Materials after Pituitary Tumor Resection with the Transnasal Endoscopic Approach

Background: Neuroendoscopic transsphenoidal approach for resection of pituitary adenomas has the advantages of less damage, fewer complications, and a faster recovery than the traditional approach and has beening favored by neurosurgeons. However, there has no standard method of selecting suitable packing materials after the operation to relieve pain in patients and achieve the ideal hemostatic effect. We compared the postoperative complications and treatment effects of two different packing materials in patients with pituitary adenomas. Objective: To investigate the advantages and disadvantages of using a catheter balloon and iodoform gauze for hemostasis in patients undergoing pituitary tumor resection by neuroendoscopic transsphenoidal approach. Materials and Methods: We retrospectively analyzed these data of 48 cases treated with pituitary adenoma resection by the single nasal approach from January 2018 to October 2019 in Sun Yat-sen University Cancer Center. According to the type of sphenoid sinus packing material used, these patients were divided into balloon tamponade oppression group (24 cases) and tela iodoformum oppression group (24 cases), respectively. The balloon tamponade oppression group received catheter balloon tamponade oppression hemostasis, and the tela iodoformum oppression group underwent tela iodoformum oppression hemostasis. The outcomes and complications were compared between the two groups in which two kinds of sphenoid sinus packing materials were used for hemostasis after tumor resection by transnasal endoscopic approach. For the catheter balloon compression hemostasis method, on account of the plasticity of the balloon, the volume of water in the balloon can be adjusted according to the size of the patient’s own sphenoid cavity. The amount of bleeding and several complications in terms of discomfort during placement and removal of the packing material, rebleeding after removal of the packing, cerebrospinal fluid rhinorrhea and electrolyte disturbance are compared between the two groups. Results: 48 patients were enrolled. The two groups’ data of patients were similar in age structure, sex ratio, tumor size at baseline and so on. No complications, such as abscess formation, were found in both groups. The success rate in the compression with catheter balloon group was 100% (24 of 24 patients);and in the iodoform gauze group 83.33% (20 of 24 patients). A catheter balloon was more successful in stopping bleeding at early stage than iodoform gauze. There were no statistically significant differences in the hospitalization stay time, operating day to discharge day and tampon indwelling time (P > 0.05). There were also no significant differences in pairwise comparison between the catheter balloon group and iodoform gauze groups in the incidence of cerebrospinal fluid rhinorrhea or electrolyte disturbance between the two groups (P > 0.05). The incidence of headache in the catheter balloon group was statistically significantly lower than that in the iodoform gauze group (P < 0.05). Conclusion: In patients undergoing endoscopic pituitary tumor resection, compression and hemostasis by means of catheterization expansion lead to lower rates of injury and complications and have a good effect, so this method is worthy of being recommended for clinical practice.

A 50-year-old woman with long standing nonspecific disturbing headaches of the mid-face and rear of the head plus retro-orbital pain for about one year duration was proved to suffer from the fungus ball involvement of the left sphenoid sinus after operation. The diagnosis was established by histopathologic examination of the specimen removed at the time of operation.

Ocular cranial nerve palsies secondary to sphenoid sinusitis

Objective:The clinical presentation of sphenoid sinusitis can be highly variable.Rarely,sphenoid sinusitis may present with cranial nerve complications due to the proximity of these structures to the sphenoid sinus.Method:A case series from Rabin Medical Center and all cases of cranial nerves palsies secondary to sphenoid sinusitis that have been reported in the literature were reviewed.Results:Seventeen patients were identified.The abducent nerve was the most common cranial nerve affected (76％),followed by the oculomotor nerve (18％).One patient had combined oculomotor,trochlear and abducent palsies.The most common pathology was isolated purulent sphenoid sinusitis in 64％ followed by allergic fungal sinusitis (AFS) in 18％,and fungal infection in 18％.94％ had an acute presentation.The majority (85％) received a combined intravenous antibiotics and surgical treatment.The remainder received conservative treatment alone.Complete recovery of cranial nerve palsy was noted in 82％ during follow up.Conclusion:Sphenoid sinusitis presenting as diplopia and headaches is rare.A neoplastic process must be ruled out and early surgical intervention with intravenous antimicrobial therapy carry an excellent outcome with complete resolution of symptoms.

Large and giant medial sphenoid wing meningiomas involving vascular structures： clinical features and management experience in 53 patients

Background Large and giant medial sphenoid wing meningiomas that are located deeply in the skull base where they are closely bounded by cavernous sinus,optic nerve,and internal carotid artery make the gross resection hard to achieve.Also,this kind of meningiomas is often accompanied by a series of severe complications.Therefore,it was regarded as a formidable challenge to even the most experienced neurosurgeons.This study aimed to investigate the clinical features and management experience of patients with large and giant medial sphenoid wing meningiomas.Methods In this study,53 patients （33 female and 20 male,mean age of 47.5 years） with large and giant medial sphenoid wing meningiomas were treated surgically between April 2004 to March 2012,with their clinical features analyzed,management experience collected,and treatment results investigated retrospectively.Results In this study,gross total resection （Simpson Ⅰ and Ⅱ） was applied in 44 patients （83％）.Fifty-three patients had accepted the routine computed tomography scan and magnetic resonance imaging scan as postoperative neuroradiological evaluation.Their performance showed surgical complications of vascular lesions and helped us evaluate patients＇ conditions,respectively.Meanwhile,the drugs resisting cerebral angiospasm,such as Nimodipine,were infused in every postoperative patient through vein as routine.As a result,11 patients （21％） were found to have secondary injury of cranial nerves Ⅱ,Ⅲ,and Ⅳ,and nine patients got recovered during the long-term observing follow-up period.Temporary surgical complications of vascular lesions occurred after surgery,such as cerebral angiospasm,ischemia,and edema;24 patients （45％） appeared to have infarction and dyskinesia of limbs.Overall,visual ability was improved in 41 patients （77％）.No patient died during the process.Conclusions Microsurgical treatment may be the most effective method for the large and giant medial sphenoid wing meningiomas.The surgical strategy should focus on survival and postoperative living quality.

Sphenoid wing meningioma en plaque： report of 37 cases

Background Sphenoid wing meningioma en plaque is a special morphological subgroup of intracranial meningiomas, defined by a carpet-like, soft tissue component that infiltrates the dura and invades the sphenoid wing and orbit associated with a significant hyperostosis. This report summarized our experiences in 37 patients with sphenoid wing meningioma en plaque who had been treated with transcranio-orbital approach surgery. Methods A retrospective study was made on clinical manifestations, neuroradiological features, and operative techniques in 37 patients undergoing transcranio-orbital approach from Sep. 1998 to Apr. 2009. Patients ages： 16 years to 67 years, 45.5 years in average; sex： 15 males, 22 females. Chief complaints were progressive proptosis and visual acuity deficits. All patients were operated on using a fronto-temporal approach with orbital decompression. The extent of tumor resection and postoperative complications were investigated. Results Simpson grade Ⅱ resection was achieved in 9 patients, Simpson grade Ⅲ in 22 patients and Simpson grade Ⅳ in 6 patients. Pathological examination showed 27 （73%） patients were meningothelial meningiomas. After surgery, proptosis improved in all patients, visual acuity improved in 18 patients （69%）. Temporary ophthalmoplegia was found in 8 patients, cerebrospinal fluid leak was found in 1 patient. Duration of follow up was from 3 months to 9 years, tumor recurred in 7 patients, and 5 patients underwent second surgery, including two trans-nasal endoscopic surgeries to resect sphenoid sinus-involved tumor. There were no operation-related deaths or other significant complications. Conclusions Sphenoid wing meningioma en plaque, mainly meningothelial meningiomas, are more likely to produce adjacent hyperostosis and have characteristic radiological appearances. All the hyperostosis bone of the great wing of sphenoid bone should be removed to prevent recurrence. Extensive tumor removal with bony decompression at the orbital apex can produce satisfactory cosmetic and functional outcome. Close co-operation between the neurosurgeons and the ophthalmologists is important.

To use non X ray comprehensive measurement for accurate localization of sublabio septo sphenoidal approach for shortening operating duration, decreasing hemorrhage, and increasing the success rate of operation Methods Operations in 122 patients suffering from tumors in the sella turcica region used non X ray localizations including localization by the angle formed by the glalella, anterior nasal spina and anterior nasal spina sella turcica; localization by the angle formed by the upper incisors, anterior nasal spina and anterior nasal spina sella turcica; and localization by anatomical markers (determination of the midline by the nasoseptum and vomer; determination of the anterior wall of the sphenoidal sinus by the foramen of the sphenoidal sinus and vomer body; correction of the site by septum of the sphenoidal sinus; location of the center of saddle by the shape of the floor of the sella and determination of the approach direction by the damaged area in the sella turcica region) were comprehensively employed Additionally, X ray localization was used to correct its accuracy Results Non X ray comprehensive localization was applied to 40 patients for determining the site and depth of the floor of the sella, and the preciseness of the measurement was confirmed with X ray Operating duration averages 2 2 hours Non X ray localization was directly applied to 82 patients for comprehensively measuring the floor of the sella, and operations were successful Operating duration averages 1 5 hours and blood transfusion averages 200?ml No deaths and severe complications occurred Conclusion Non X ray comprehensive measurement can be directly applied for precisely localizing the floor of the sella

Invasive sphenoid sinus aspergillosis mimicking sellar tumor: a report of 4 cases and systematic literature review

Background:Invasive sphenoid sinus aspergillosis is a rare but life-threatening condition usually found in immunocompromised patients.When involving cavernous sinus and surrounding structures,patients are frequently misdiagnosed with a neoplasm or sellar abscess.Timely diagnosis and intervention are crucial to patients’outcomes.The objective of this study is to review cases of invasive sphenoid sinus aspergillosis to describe disease manifestations,imaging features,treatment,and outcome.Case presentation:We describe four patients with invasive sphenoid sinus aspergillosis misdiagnosed as sellar tumors preoperatively.The mass was completely removed in three patients and partially removed in one patient microscopically.Pathological examinations confirmed Aspergillus in all cases.All four patients received anti-fungal agents postoperatively.There was no recurrence at the time of each patient’s follow-up date.One patient with complete resection was lost to follow-up while the other three patients’neurologic function improved.Additionally,we performed a systematic review regarding invasive sphenoid sinus aspergillosis of existing English literature.Conclusion:With regard to clinical symptoms,headache,vision impairment,and ophthalmoplegia were observed in over half of the patients in the literature.A sellar mass with bone destruction on CT and involvement of cavernous sinus is highly suggestive of invasive fungal sphenoid sinusitis.Immediate surgical removal of the lesion is recommended for invasive sphenoid sinus aspergillosis to preserve nerve function and increase the likelihood of survival.

Microsurgical treatment of cerebrospinal fluid rhinorrhea in sphenoidal sinus

Objective：To explore the clinical manifestation,diagnosis and surgical treatment of cerebrospinal fluid rhinorrhea in sphenoidal sinus.Methods： Nine cases of cerebrospinal fluid rhinorrhea in spenoidal sinus from 2007 to 2009 were retrospectivelyanalyzed consisting of their possible etiological factors,clinical manifestations, localization of the leakage site and treatment methods. Among them, there were 3 cases of traumatic rhinorrhea, 4 postoperative rhinorrhea and 2 spontaneous rhinorrhea. All 9 patients underwent 3-dimensional CT scan in sellar region including all para-nasal sinus. Leakage site was identified and repairing procedure was performed through trans-sphenoidal approach.Results：All cases were cured with the trans-sphenoidal microsurgical procedure. They were followed up for 9 months to 2 years. No recurrence, no infection and epilepsy complications were observed.Conclusion：For the cerebrospinal fluid rhinorrhea at sphenoidal sinus, it is critical to identify the leakage site accurately and the trans-sphenoidal approach is a microinvasive and effective way to repair the leakage, which is worthy to be advocated.
