Background: The clinical presentation of sphenoid sinus meningoencephaloceles (MEC) may have insidious onset and evolution. Contemporary treatment incorporates endoscopic resection via the endonasal route.Case description: We present a case of 3 year old girl who had been complaining of permanent nasal discharge, impeded nasal breathing and difficulty with feeding since she was 5 months old. There was no history of rhinoliquorrhea. Pre-operative magnetic resonance imaging demonstrated MEC that extended from the sellar region through the non-pneumatized sphenoid sinus to the nasopharynx. The lesion was resected via endoscopic endonasal approach. Follow-up rhinoscopy confirmed the absence of post-operative cerebrospinal fluid leak.Conclusion: Endoscopic endonasal approach can be an effective and a safe treatment option for resection of congenital transsphenoidal MEC in early childhood.Keywords: Sphenoid sinus; endoscopic endonasal approach; meningoencephalocele; CSF leak; congenital.

Extracapsular Resection

IntroductionThe endoscopic endonasal approach (EEA) is a safe and effective treatment for pituitary adenomas (PAs). Since extracapsular resection (ER) of PAs improves tumor resection and endocrine remission rates, the interface between the pseudocapsule and gland draws increasing attention. However, it is difficult to precisely dissect the tumor along the exact boundary, and complete removal of the tumor increases the risks of normal tissue damage and cerebrospinal fluid (CSF) leakage. In this study, we investigated the extracapsular resection as well as the pseudocapsule histology to evaluate the effectiveness and safety of pseudocapsule-related surgical interventions.MethodsFrom December 2017 to December 2019, 189 patients of PAs via EEA in our single center were analyzed retrospectively. The images, operative details, and clinical follow-up of patients were collected. Sixty-four patients underwent pseudocapsule-based ER, and 125 patients also underwent traditional intracapsular resection (IR) with or without intensive excision for FPAs. The clinical characteristics, tumor resection, endocrinological outcomes, and postoperative morbidities of the two groups were compared. Informed consent for publication of our article was obtained from each patient. Histological examination of pseudocapsule was performed using hematoxylin and eosin and reticulin staining.ResultsThe gross total recession was 62 (96.9%) in the ER group and 107 (85.6%) cases in the IR group, whereas the endocrine remission rate was 29/31 (93.5%) and 40/53 (75.5%) cases, respectively. Anterior pituitary functions were not aggravated postoperatively in any patient, but transient diabetes insipidus (DI) occurred more in the IR group (64.0%) than in ER (48.4%). Pseudocapsule specimens were obtained in 93 patients, and clusters of small cell aggregation were detected in 11 pseudocapsule specimens (11.8%) whereas other patients showed no remarkable developed pseudocapsule. Intraoperative CSF leak occurred more in the ER group (28.1%) than in the IR group (13.6%), but no difference was seen between two groups postoperatively. No case of intracranial hematoma or pituitary crisis occurred in both groups. After a mean follow-up of 22.8 months, tumor recurrence was observed in 4 (2.1%) cases.ConclusionPseudocapsule-based extracapsular resection of PAs via EEA is an effective and safe procedure to achieve complete resection with high and sustained endocrine remission and without deteriorating pituitary function.

Introduction Surgery has been the standard treatment for Cushing's disease. Currently, the endoscopic endonasal approach (EEA) is the most widely used technique. However, among some endocrinologists and neurosurgeons used to the microscope assisted technique, there are still questions about the effectiveness and safety of transitioning to the EEA. We aim to show our initial experience with such transition. Method Retrospective review of medical records of patients, who underwent EEA in our center as a first treatment for Cushing's disease, and with a minimum 18 months of follow-up, from March 2004 to March 2014 Results Our cohort had 16 patients (14 females and 2 males), with a mean age of 33.7 years. The mean follow-up was 52.0 months. Magnetic resonance imaging (MRI) identified an adenoma in 93.8% of the patients (56.2% microadenomas and 37.5% macroadenomas). Postoperative cerebrospinal fluid (CSF) leak was observed in two patients (12.5%). No new neurological deficits were present after surgery. The early remission and sustained remission rates after a single procedure were 87.5 and 68.75%, respectively. Weight reduction, improved control of blood pressure, and lower serum glucose levels were documented in 68.75, 60, and 55.5% of patients, respectively, after remission. Conclusion Despite the need for specialized training, equipment and team building by ENT (Ear, Nose and Throat) and neurosurgery, the transition from microscope assisted pituitary surgery to endoscopic endonasal approach is possible and safe. The clinical outcomes, even in the early years, are similar to the previous microscope assisted treatment, and over time, with greater experience and knowledge, there is a tendency for improvement.

Background: Traditionally petrous apex lesions surgical approach is associated with multiple complications including brain injury secondary to brain retraction. Expanded endoscopic endonasal trans-clival (EEET) can be used in selected patients with minimal complications. Methods: We are presenting our experience over the last three years in patients who underwent EEET resection of petrous apex lesions: 8 patients underwent such procedure. All patients underwent extensive workup including MRI and CTA to identify the relation of the carotid to the lesion. All surgeries were done with neuro-physiological monitoring. Intraoperative neuronavigation and endoscopic Doppler were used to identify the petrous segment of the internal carotid artery. Our follow up ranged from 6 months to 2.5 years. Results: All patients presented with severe neurologic symptoms related to either fifth cranial nerve, sixth cranial nerve or brain stem compression. Pathologies included chondrosarcoma, cholesterol granulomas and lymphangioma. All patients demonstrated improvement in their symptoms. None of our patients had intra-operative vascular injury. There was no post-operative CSF leak or infection. Postoperative imaging demonstrated excellent resection with no clear residual. Three patient required adjuvant stereotactic radiosurgery because of their underlying pathology. Conclusions: The expanded endoscopic endonasal approach for petrous apex lesion should be considered as a minimally invasive approach in selected cases.

Abstract OBJECTIVE In recent years, the endoscopic endonasal approach (EEA) has been increasingly used for pediatric craniopharyngiomas. We here present our experience and the outcomes of the EEA resection of pediatric craniopharyngiomas. MATERIALS AND METHODS Between April 2014 and December 2019, 16 cases of pediatric craniopharyngiomas were operated at the Osaka city university (OCU) hospital. Eight patients were diagnosed with primary craniopharyngiomas while 8 had a recurrent tumor. There were 5 males and 11 females, with a mean age of 10.7 years (3–17 years). EEA was selected in all patients and a case of large muti-lobulated tumor was resected by combination of microscopic transcranial approach. RESULTS Gross total resection was achieved in 14 patients and near total resection in other 2. Post-op CSF leak occurred in 3 patients, which was treated with re-exploration. Pituitary stalk was preserved intraoperatively in 4 cases, and 15 patients developed diabetes insipidus and anterior hormonal replacement therapy was required in 15 patients at last follow-up. Visual improvement was noted in 4 patients while vision remained unchanged in the rest. Neuropsychological function status was preserved in all patients, and there was no new-onset obesity postoperatively. The mean follow-up duration was 35.1 months (2 – 69 months) and 4 of 8 recurrent cases had re-recurrence during this period, however there was no recurrent in 8 primary cases. CONCLUSIONS EEA should be the surgical modality of choice for treating pediatric craniopharyngiomas. It results in better visual and cognitive outcomes with a significantly increased extent of resection.

Clinical Records

Greater superficial petrosal nerve (GSPN) schwannomas are an exceedingly rare nerve sheath tumor. The current literature search was conducted using Medline and Embase database by key search terms. Only 31 cases have been reported in the literature so far. Facial palsy, hearing loss, and xerophthalmia accounted for 48.4% (15), 41.9% (13), and 29% (9) of all cases, respectively. The middle cranial fossa approach was used in all previous reports. A retrospective review of 2 GSPN schwannomas patients treated by endoscopic endonasal approach (EEA) in our center was collected. Clinical records, including clinical features, pre- and postoperative images, surgery, and follow-up information, were reviewed. In all cases, clinical features including facial numbness and headache were found, with tinnitus in case 1, hearing loss, xerophthalmia in case 2. Imaging studies showed a solid mass that originated in the anterior of the petrous bone. Two patients were treated by EEA. Furthermore, no recurrence was found during the follow-up period (15-29 months) in both of the 2 cases after the operation. Complete resection of GSPN schwannomas can be achieved via the pure EEA. Endoscopic endonasal approach for radical removal of tumors is safe and feasible.

Abstract Background Despite the use of vascularized intranasal flaps, endoscopic endonasal posterior fossa defects remain surgically challenging with high rates of postoperative cerebrospinal fluid leak. Objective The aim of the study is to describe a novel surgical technique that allows complete drilling of the clivus and exposure of the craniovertebral junction with preservation of the nasopharynx. Methods Two formalin-fixed latex-injected anatomical specimens were used to confirm feasibility of the technique. Two surgical approaches were used: sole endoscopic endonasal approach and transnasion approach. The sole endonasal approach was used in a patient with a petroclival meningioma. Results In both anatomical dissections, the inferior clivectomy with exposure of the foramen magnum was achieved with a sole endoscopic endonasal approach. The addition of the transnasion approach helped to complete drilling of the inferior border of the foramen magnum and exposure of the arch of C1. Conclusion This study shows the anatomical feasibility of total clivectomy and exposure of the craniovertebral junction with preservation of the nasopharynx. A more favorable anatomical posterior fossa defect for the reconstruction is achieved with this technique. Further clinical studies are needed to assess if this change would impact the postoperative CSF leak rate.

A 58-year-old man presented with a six-month history of intermittent blood-stained posterior nasal discharge. Five years ago, he had a three-week episode of fitful light headaches. Nasal ventilation, olfactory sensation, and facial sensation were normal; there were no ophthalmological complaints. Coronal computed tomography (CT) scans revealed soft masses in the bilateral sphenoid sinuses with bone absorption. The patient underwent bilateral functional endoscopic sinus surgery and resection of right nasal papillary masses. Papillary masses and mucosa in both sphenoid sinuses were also removed. The mass in the left sphenoid sinus was diagnosed as two separate entities, one being a primary monophasic epithelial synovial sarcoma and the other an inverted papilloma, while the mass in the right sphenoid sinus was an inverted papilloma. After surgery, the patient underwent radiotherapy and chemotherapy. At the 50-month follow-up visit, there were no signs of recurrence.

OBJECTIVEMachine learning (ML) is an innovative method to analyze large and complex data sets. The aim of this study was to evaluate the use of ML to identify predictors of early postsurgical and long-term outcomes in patients treated for Cushing disease (CD).METHODSAll consecutive patients in our center who underwent surgery for CD through the endoscopic endonasal approach were retrospectively reviewed. Study endpoints were gross-tumor removal (GTR), postsurgical remission, and long-term control of disease. Several demographic, radiological, and histological factors were assessed as potential predictors. For ML-based modeling, data were randomly divided into 2 sets with an 80% to 20% ratio for bootstrapped training and testing, respectively. Several algorithms were tested and tuned for the area under the curve (AUC).RESULTSThe study included 151 patients. GTR was achieved in 137 patients (91%), and postsurgical hypersecretion remission was achieved in 133 patients (88%). At last follow-up, 116 patients (77%) were still in remission after surgery and in 21 patients (14%), CD was controlled with complementary treatment (overall, of 131 cases, 87% were under control at follow-up). At internal validation, the endpoints were predicted with AUCs of 0.81–1.00, accuracy of 81%–100%, and Brier scores of 0.035–0.151. Tumor size and invasiveness and histological confirmation of adrenocorticotropic hormone (ACTH)–secreting cells were the main predictors for the 3 endpoints of interest.CONCLUSIONSML algorithms were used to train and internally validate robust models for all the endpoints, giving accurate outcome predictions in CD cases. This analytical method seems promising for potentially improving future patient care and counseling; however, careful clinical interpretation of the results remains necessary before any clinical adoption of ML. Moreover, further studies and increased sample sizes are definitely required before the widespread adoption of ML to the study of CD.

Significant Difference

Background Sinonasal inverted papilloma (SNIP) is noted for its high rate of recurrence and malignant transformation. Although many clinical studies have demonstrated the effectiveness of the endoscopic approach for SNIP, the surgical strategy has been the subject of much debate. Objective To evaluate the effectiveness of the endoscopic endonasal approach in SNIP. Methods A systematic review of patients with a diagnosis of SNIP and who had surgery at our institution from June 2005 to March 2013 was performed. All the patients who had postoperative follow-up for >2 years were enrolled. Each case was categorized into one of four stages as reported by Krouse. Demographic and tumor date, operative approach, complications, and recurrence rates were collected. Results A total of 125 patients were included in this study. There were 17 patients in stage 1, 40 in stage 2, 57 in stage 3, and 11 in stage 4. The overall recurrence rate was 8.0%. There was no significant difference in recurrence among the stages (all p > 0.05). Recurrence after endoscopic endonasal approach (8.4%) and a combined endoscopic and open exposure procedure (5.6%) were not significantly different (p > 0.05). The recurrence rate was significantly (p < 0.05) higher in patients with revision (15.6%) than in patients in the primary cases (3.8%). A common site of tumor origin was recorded to be from the maxillary sinus (40.2%). Twenty percent of recurrences were observed up to 5 years after surgery. Conclusion Endoscopic surgery may be preferred for treating SNIP. The elevated recurrence rate after revision emphasized the significance of the first surgery. We encourage a follow-up period of at least 5 years.

Operative Assessment

Haemangiopericytomas are rare peri-vascular tumours with variable malignant potential. The nasal cavity and the paranasal sinuses are most often involved in the head and neck. Five cases of haemangiopericytomas treated by a strict endonasal endoscopic approach are presented. Bleeding and nasal obstruction are the most frequent symptoms. Computed tomography (CT) scan and magnetic resonance imaging (MRI) allowed pre-operative assessment. Angiography with embolization was needed in two of the five cases. None of our patients presented with malignant histology. Our five cases were operated on, and a total tumour excision was performed through the endoscopic endonasal approach. We had one recurrence with a mean follow-up of 4.5 years. We suggest that when the tumour is purely intranasal or strictly located in the ethmoid or sphenoid sinus, it can be removed via an endonasal approach under endoscopic guidance in experienced hands.
