[PMID: 38861352 DOI: 10.1097/scs.0000000000010415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Accepted: 05/21/2024] [Indexed: 06/13/2024] Open
Abstract
OBJECTIVE To summarize the application experience of the pneumatic arm in transnasal sphenoidal pituitary adenoma resection under neuroendoscope. METHODS A retrospective analysis was conducted on the clinical data of 52 patients with pituitary adenoma who underwent endoscopic transsphenoidal surgery with pneumatic arm fixation in the Neurosurgery Department of the First Affiliated Hospital of Anhui Medical University from July 2021 to March 2024. Among them, there were 5 cases of pituitary microadenoma, 35 cases of macroadenoma, and 12 cases of giant adenoma. Head CT and a full set of hormones were re-examined within 24 hours after surgery to evaluate the surgical effect. Follow-up was conducted by the outpatient department after surgery to assess the clinical symptoms, hormone level, and imaging of all patients. RESULTS Among 52 patients, gross total resection was achieved in 48 cases (92.3%), subtotal resection in 3 cases (5.8%), and partial resection in 1 case (1.9%). Preoperatively, 43 patients had diminished vision, with 40 showing improvement postoperatively, 1 worsening, and 2 having no significant improvement. Thirty-eight patients had headaches preoperatively, and all showed varying degrees of improvement postoperatively. Routine hormone examination within 24 hours after surgery showed that all 20 prolactinoma patients had restored normal hormone levels, 10 of 12 growth hormone-secreting adenoma patients normalized, and 4 of 6 cases of adrenocorticotropic hormone-secreting adenoma immediately relieved after surgery. Postoperative complications included intracranial hematoma in 1 case, cerebrospinal fluid leakage in 2 cases, transient diabetes insipidus in 6 cases, intracranial infection in 1 case, and no death cases. The median follow-up time of 52 patients was 18.6 months (range: 1-32 mo). During the follow-up period, the initial clinical symptoms of all patients improved to varying degrees, and they were able to work and live normally. At the last follow-up, 1 patient had recurrent tumor and 1 patient had progression. CONCLUSION Transnasal sphenoidal resection of pituitary adenoma using a pneumatic arm-fixed neuroendoscope allows the operator to perform the surgery with both hands, resulting in satisfactory overall tumor resection and fewer surgical complications. This technique has good clinical value for promotion.

Elwy R, Younes AR, Elsamman AK. Effect of the extent of posterior septectomy on surgical access during the endoscopic endonasal approach to the sella: A technical note. BRAIN & SPINE 2024; 4:102831. [PMID: 38807920 PMCID: PMC11130681 DOI: 10.1016/j.bas.2024.102831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Revised: 04/29/2024] [Accepted: 05/06/2024] [Indexed: 05/30/2024]
Abstract
Background Using the bi-nostril 4-hand technique during the endoscopic endonasal approach (EEA) facilitates bimanual microsurgical techniques yet requires resection of the posterior nasal septum. The surgical exposure and degree of maneuverability gained proportionate to the extent of posterior septectomy in the sagittal plane was previously quantified. Research question We aim to describe our technique of posterior septectomy, and the effect of its extent in the axial plane on surgical access, and instrument maneuverability. Material and methods After fracturing the posterosuperior nasal septum, we disarticulate the vomer from the sphenoid rostrum and remove its upper part. The sphenoid rostrum is excised next exposing the clival recess where a suction tip without a side channel is anchored, allowing the assisting surgeon to use an additional instrument in their dominant hand. The vomer is removed down to the level of the floor of the sphenoid sinus. Results A wide exposure is achieved in the coronal plane bilaterally at the level of the sphenoid rostrum allowing unobstructed instrument manipulation in the craniocaudal and cross-court trajectories. Furthermore, the floor of the sella is reached through a straight rather than angled trajectory facilitating surgical access, manipulation, and instrument maneuverability. For lateral lesions requiring contralateral access, the assisting surgeon can assist in dissection from the contralateral nostril without changing the position of the endoscope. Discussion and conclusion Removing the upper vomer improves surgical access, and instrument maneuverability. Simultaneous dissection from both nostrils might be attempted. Caudally extending the posterior septectomy during the EEA allows better exposure and improves surgical access in all planes.

Abstract
Pituitary adenomas are slow-growing, benign intracranial tumors that can be characterized as functional (hormone-producing) or non-functional (non-hormone producing). Symptoms therefore arise from either endocrinologic abnormalities or mass effect on surrounding structures resulting in symptoms such as visual impairment and headache. In the last two decades, technical innovations have shifted surgical resection of such adenomas to endoscopic endonasal approaches. In this review, we describe the evolving approach to pituitary adenomas in the modern endoscopic era, including preoperative multidisciplinary review, relevant surgical anatomy, and a description of the technical nuances of standard and expanded approaches to the anterior skull base.

The impact of time to evacuation on outcomes in endoscopic surgery for supratentorial spontaneous intracerebral hemorrhage: a single-center retrospective study. Neurosurg Rev 2023; 47:2. [PMID: 38057420 DOI: 10.1007/s10143-023-02237-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 11/29/2023] [Accepted: 12/03/2023] [Indexed: 12/08/2023]
Abstract
Supratentorial spontaneous intracerebral hemorrhage (SICH) can be treated with endoscopic surgery, but the optimal timing remains uncertain. We retrospectively analyzed data from 46 patients who underwent endoscopic surgery for supratentorial SICH. We examined the relationship between time to evacuation and functional outcome at 3 months, adjusting for prognostic factors. Surgical outcomes and complications were compared between patients with early (≤ 12 h) or late (> 12 h) evacuation. Median time to evacuation was 12 h, and the rate of unfavorable outcome (modified Rankin Scale > 3 at 3 months) was 32.6%. Longer time to evacuation was independently associated with unfavorable outcome (odds ratio per hour delay: 1.26). Late evacuation carried a 7.25-fold higher risk of unfavorable outcome compared to early evacuation. This association held across subgroups based on hematoma volume, location, and intraventricular extension (P for interaction > 0.05). Patients with late evacuation had fewer spot signs (24% vs. 4.8%, P = 0.035) and markers of hemorrhagic expansion (36% vs. 9.5%, P = 0.018), longer neurosurgical intensive care unit (NSICU) stay (3.2 vs. 1.9 days, P = 0.011) and hospital stay (15.7 vs. 11.9 days, P = 0.014), and higher 30-day mortality (28.6 vs. 4%, P = 0.036) and complication rates (57.1% vs. 28.0%, P = 0.023). This study suggests a potential association between early endoscopic evacuation of supratentorial SICH and improved functional outcomes, lower 30-day mortality and reduced complications. The need for timely intervention in managing supratentorial SICH is highlighted, yet further validation through multi-center prospective studies is essential to substantiate these findings and provide a higher level of evidence.

Comparison of the Novel Two-Hand Technique Using the Saraj Endocath with the Traditional Three-Hand Technique in Transnasal Endoscopic Pituitary Surgery: An Innovation for the Future. World Neurosurg 2023; 178:e791-e801. [PMID: 37572834 DOI: 10.1016/j.wneu.2023.08.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND Endoscopic surgery has become the preferred treatment of sellar lesions because of its minimally invasive nature. Visualization is frequently obscured as a result of the frequent contact of the lens with blood and tissue debris. We seek to alleviate these problems and increase the efficiency and safety of neuroendoscopic surgery by introducing a new device (Saraj Endocath) combining the major function of suction with the endoscope. METHODS A total of 75 patients with pituitary macroadenoma who were eligible for transnasal transsphenoidal endoscopic excision were included in the study between January 2020 and January 2023. Forty-one patients were operated on by the traditional 3-hand technique and 34 patients were operated on using the Saraj Endocath. The duration of surgery, in-out frequency of the endoscope, number of wipes needed to clean the endoscopic lens, and outcomes were assessed. A questionnaire regarding assistance, ergonomics, and instrument handling compared the Saraj Endocath procedure with the traditional technique. RESULTS The 3-hand technique was converted into the 2-hand technique. The mean operative time using the novel technique with the Saraj Endocath was reduced significantly compared with the traditional technique. The mean number of in-out movements of the endoscope and the number of wipes per hour decreased significantly using the Saraj Endocath. There was no dependency on the assistant's expertise and skills. CONCLUSIONS The use of the Saraj Endocath can effectively reduce the mean operative time by decreasing the frequency of in-out movement and wiping off the lens of the endoscope. It reduces fatigue, avoids clustering of instruments and hands, and minimizes the dependency on assistants.

Abstract
Background Choroid plexus papilloma (CPP) is rare and even rarer in infants and young children, and it usually occurs in the ventricles. Due to the physical peculiarities of infants, tumor removal by microscopic or endoscopic surgery alone is difficult. Case Presentation A 3-month-old patient was found to have an abnormally enlarged head circumference for 7 days. Cranial magnetic resonance imaging (MRI) examination revealed a lesion in the third ventricle. The patient underwent combined microscopic and endoscopic "chopstick" technique to remove the tumor. He recovered well after the surgery. Postoperative pathological examination revealed CPP. Postoperative MRI suggested total resection of the tumor. Follow-up for 1 month showed no recurrence or distant metastasis. Conclusions Combined microscopic and endoscopic "chopstick" technique may be a suitable approach to remove tumors in infant ventricles.

Abstract
OBJECTIVE Chordomas represent one of the most challenging subsets of skull base and craniovertebral junction (CVJ) tumors to treat. Despite extensive resection followed by proton-beam radiation therapy, the recurrence rate remains high, highlighting the importance of developing efficient treatment strategies. In this study, the authors present their experience in treating clival and CVJ chordomas over a 29-year period. METHODS The authors conducted a retrospective study of clival and CVJ chordomas that were surgically treated at their institution from 1991 to 2020. This study focuses on three aspects of the management of these tumors: the factors influencing the extent of resection (EOR), the predictors of survival, and the outcomes of the endoscopic endonasal approaches (EEAs) compared with open approaches (OAs). RESULTS A total of 265 surgical procedures were performed in 210 patients, including 123 OAs (46.4%) and 142 EEAs (53.6%). Tumors that had an intradural extension (p = 0.03), brainstem contact (p = 0.005), cavernous sinus extension (p = 0.004), major artery encasement (p = 0.01), petrous apex extension (p = 0.003), or high volume (p = 0.0003) were significantly associated with a lower EOR. The 5-year progression-free survival (PFS) and overall survival (OS) rates were 52.1% and 75.1%, respectively. Gross-total resection and Ki-67 labeling index < 6% were considered to be independent prognostic factors of longer PFS (p = 0.0005 and p = 0.003, respectively) and OS (p = 0.02 and p = 0.03, respectively). Postoperative radiation therapy correlated independently with a longer PFS (p = 0.006). Previous surgical treatment was associated with a lower EOR (p = 0.01) and a higher rate of CSF leakage after EEAs (p = 0.02) but did not have significantly lower PFS and OS compared with primary surgery. Previously radiation therapy correlated with a worse outcome, with lower PFS and OS (p = 0.001 and p = 0.007, respectively). EEAs were more frequently used in patients with upper and middle clival tumors (p = 0.002 and p < 0.0001, respectively), had a better rate of EOR (p = 0.003), and had a lower risk of de novo neurological deficit (p < 0.0001) compared with OAs. The overall rate of postoperative CSF leakage after EEAs was 14.8%. CONCLUSIONS This large study showed that gross-total resection should be attempted in a multidisciplinary skull base center before providing radiation therapy. EEAs should be considered as the gold-standard approach for upper/middle clival lesions based on the satisfactory surgical outcome, but OAs remain important tools for large complex chordomas.

Abstract
Background To report the initial experience of surgery for non-functioning pituitary adenoma (NFPA) from a neurosurgeon in a dedicated residency training endoscopic transsphenoidal (ETS) program, and detail the surgical and clinical outcomes during this period. Methods A prospective series of all patients operated for NFPA, using an ETS approach, during the three first years of experience of a newly board-certified neurosurgeon was analysed. Clinical, radiological and peri-operative data were collected. Extent of resection (EOR) was determined by formal volumetric analysis. Impact of the learning curve and predictive factors of gross total resection (GTR) were determined. Results Fifty-three patients with NFPA were included in this prospective cohort which was divided in two periods of time (“First period”: 30 first cases, and “second period”: 23 following cases). Baseline characteristics of the patients in the two periods were similar. Overall occurrence of complication was 22% and was not significantly different in the two periods of time. No patient had severe neurological complication. Gross total resection was achieved in 70% of patients. Mean Extent of resection was 96%. In a multiple linear regression model, a higher EOR was positively correlated with experience (p = 0.018) and negatively correlated with Knosp Score equal to 4 (p < 0.001). Predictive factors for GTR were Higher Knosp grade (p = 0,01), higher pre-operative volume (p = 0.03), and second period of time (p = 0.01). Conclusion NFPA surgery can be safe and efficient during the learning period. Dedicated intensive learning, careful patient selection and multidisciplinary work are key to shorten the learning curve and achieve satisfactory results.

Abstract
OBJECTIVE Craniocervical junction (CCJ) chordomas are a neurosurgical challenge because of their deep localization, lateral extension, bone destruction, and tight relationship with the vertebral artery and lower cranial nerves. In this study, the authors present their surgical experience with the endoscope-assisted far-lateral transcondylar approach (EA-FLTA) for the treatment of CCJ chordomas, highlighting the advantages of this corridor and the integration of the endoscope to reach the anterior aspect and contralateral side of the CCJ and the possibility of performing occipitocervical fusion (OCF) during the same stage of surgery. METHODS Nine consecutive cases of CCJ chordomas treated with the EA-FLTA between 2013 and 2020 were retrospectively reviewed. Preoperative characteristics, surgical technique, postoperative results, and clinical outcome were analyzed. A cadaveric dissection was also performed to clarify the anatomical landmarks. RESULTS The male/female ratio was 1.25, and the median age was 36 years (range 14-53 years). In 6 patients (66.7%), the lesion showed a bilateral extension, and 7 patients (77.8%) had an intradural extension. The vertebral artery was encased in 5 patients. Gross-total resection was achieved in 5 patients (55.6%), near-total resection in 3 (33.3%), and subtotal resection 1 (11.1%). In 5 cases, the OCF was performed in the same stage after tumor removal. Neither approach-related complications nor complications related to tumor resection occurred. During follow-up (median 18 months, range 5-48 months), 1 patient, who had already undergone treatment and radiotherapy at another institution and had an aggressive tumor (Ki-67 index of 20%), showed tumor recurrence at 12 months. CONCLUSIONS The EA-FLTA provides a safe and effective corridor to resect extensive and complex CCJ chordomas, allowing the surgeon to reach the anterior, lateral, and posterior portions of the tumor, and to treat CCJ instability in a single stage.

Abstract
BACKGROUND Extended endoscopic endonasal approaches (EEAs) have progressively widened the armamentarium of skull base surgeons. In order to reduce approach-related morbidity of EEAs and closure techniques, the development of alternative strategies that minimize the resection of normal tissue and alleviate the use of naso-septal flap (NSF) is needed. We report on a novel targeted approach to the clivus, with incision and closure of the mucosa of the rostrum, as the initial and final step of the approach. OBJECTIVE To present an alternative minimally invasive approach and reconstruction technique for selected clival chordomas. METHODS Three cases of clival chordomas illustrating this technique are provided, together with an operative video. RESULTS The mucosa of the rostrum is incised and elevated from the underlying bone, as first step of surgery. Following tumor resection with angled scope and instruments, the mucosa of the sphenoid sinus (SS) is removed and the tumor cavity and SS are filled with abdominal fat. The mucosal incision of the rostrum is then sutured. A hangman knot is prepared outside the nasal cavity and tightened after the first stitch and a running suture is performed. CONCLUSION We propose, in this preliminary report, a new targeted approach and reconstruction strategy, applying to EEAs the classic concept of skin incision and closure for transcranial approaches. With further development in the instrumentations and visualization tools, this technique may become a valuable minimally invasive endonasal approach for selected lesions.

Assessing the surgical outcome of the "chopsticks" technique in endoscopic transsphenoidal adenoma surgery. Neurosurg Focus 2020; 48:E15.

Abstract
OBJECTIVE The "chopsticks" technique is a 3-instrument, 2-hand mononostril technique that has been recently introduced in endoscopic neurosurgery. It allows a dynamic surgical view controlled by one surgeon only while keeping bimanual dissection. Being a mononostril approach, it requires manipulation of the mucosa of one nasal cavity only. The rationale of the technique is to reduce nasal morbidity without compromising surgical results and complication rates. There are, however, no data available on its results in endoscopic surgery (transsphenoidal surgery [TSS]) for pituitary adenoma. METHODS The authors performed a cohort analysis of prospectively collected data on 144 patients (156 operations) undergoing TSS using the chopsticks technique with 3T intraoperative MRI. All patients had at least 3 months of postoperative neurosurgical, endocrinological, and rhinological follow-up (Sino-Nasal Outcome Test-20 [SNOT-20] and Sniffin' Sticks). The surgical technique is described, and the achieved gross-total resection (GTR) and extent of resection (EOR) together with patients' clinical outcomes and complications are descriptively reported. RESULTS On 3-month postoperative MRI, GTR was achieved in 71.2% of patients with a mean EOR of 96.7%. GTR was the surgical goal in 122 of 156 cases and was achieved in 106 of 122 (86.9%), with a mean EOR of 98.7% (median 100%, range 49%-100%). There was no surgical mortality. At a median follow-up of 15 months (range 3-70 months), there was 1 permanent neurological deficit. As of the last available follow-up, 11.5% of patients had a new pituitary single-axis deficit, whereas 26.3% had improvement in endocrinological function. Three patients had new postoperative hyposmia. One patient had severe impairment of sinonasal function (SNOT-20 score > 40). The operation resulted in endocrine remission in 81.1% of patients with secreting adenomas. CONCLUSIONS This study shows that the chopsticks technique confers resection and morbidity results that compare favorably with literature reports of TSS. This technique permits a single surgeon to perform effective endoscopic bimanual dissection through a single nostril, reducing manipulation of healthy tissue and thereby possibly minimizing surgical morbidity.

Abstract
BACKGROUND Surgical treatment of lesions involving the ventral craniovertebral junction (CVJ) and the lower clivus, traditionally involved complex lateral or transoral approaches to the skull base. However, mid or upper clivus involvement requires more extensive lateral approaches. Recently, the endoscopic endonasal approach (EEA) has become the standard for upper CVJ lesions and medial clival, and a valuable alternative for those tumors extending in its upper third as well as laterally. However, the EEA is associated with an increased risk of post-operative CSF leakage and infection when the tumor is characterized by an intradural extension. Furthermore, whenever the tumor has significant lateral and/or inferior extension below the odontoid process, the chances for a complete resection decrease. METHOD To analyze the extent of exposure of a hybrid microscopic-endoscopic transcondylar antero-lateral approach to the CVJ and clival region, and to verify its effectiveness in terms of mid and upper clival access. Five silicone-injected cadaver heads were used. Following a standard antero-lateral approach, condylectomy and jugular tubercle drilling were performed, after which angled endoscopes were utilized to extend the bone resection to the clivus. A volumetric assessment of the amount of clival removal was carried out. A case of CVJ chordoma operated through this approach is presented. RESULTS The hybrid antero-lateral transcondylar approach provides adequate exposure of the ventral CVJ, up to the dorsum sellae and the sphenoid sinus, the contralateral petrous apex, and the contralateral paraclival internal carotid artery (ICA). Approximately 60% of the total clival volume can be removed with this approach. The main limitation is the limited visualization of the ipsilateral paraclival ICA and petrous apex. CONCLUSION The hybrid antero-lateral transcondylar approach is a valuable surgical option for CVJ tumor extending from C2 to the mid and upper clivus.

Endoscopic endonasal approach to the mesial temporal lobe: anatomical study and clinical considerations for a selective amygdalohippocampectomy. Acta Neurochir (Wien) 2020; 162:881-891.

Abstract
BACKGROUND Selective amygdalohippocampectomy (AH) is a surgical option for patients with medically intractable seizures from mesial temporal lobe pathology. The transcranial route is considered the best method to achieve this goal. However, the standard approach through the neocortex is still invasive. The risks can be minimized if the mesial temporal lobe is resected while preserving the lateral temporal lobe and the Meyer's loop. This study explores the feasibility of selective AH by endoscopic endonasal approach (EEA) in cadaveric specimens. METHODS The endoscopic anatomy of the mesial temporal lobe and the feasibility of a successful selective AH were studied in six hemispheres from three injected human cadavers. Quantitative analyses on the extent of resection and angles of exposure were performed based on CT and MRI studies of pre- and post-selective AH and measurements taken during dissections. RESULTS The EEA V1-V2 corridor provided a direct and logical line of access to the mesial temporal lobe, following its natural trajectory with no brain retraction and minimal exposure of the pterygopalatine fossa. The components of the mesial temporal lobe were resected just as selectively and easily as the transcranial route, but without compromising the structures of the lateral temporal lobe or the Meyer's loop. CONCLUSIONS The EEA V1-V2 corridor demonstrated its selective resectability and accessibility of the mesial temporal lobe in cadaveric specimens. The clinical value of this approach should be explored responsibly by a surgeon with both competent microsurgical skills and experiences in EEA.
