RESUMO
INTRODUCTION: We aimed to compare early postoperative patient-reported outcomes between multiportal robotic-assisted thoracoscopic surgery (M-RATS) and uniportal video-assisted thoracoscopic surgery (U-VATS) for non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS: Symptom severity and functional status were measured using the Perioperative Symptom Assessment for Lung Surgery at pre-surgery, during postoperative hospitalisation, and within 4 weeks of discharge. A propensity score-matched (PSM) analysis of patients with NSCLC who were treated with M-RATS and U-VATS was performed. The symptom severity and daily functional status presented as proportion of moderate-to-severe scores on a 0-10-point scale, were compared using a generalised estimation equation model. RESULTS: We enrolled 762 patients with NSCLC from a prospective cohort (CN-PRO-Lung 3), including 151 and 611 who underwent M-RATS and U-VATS, respectively, before PSM analysis. After 1:1 PSM, two groups of 148 patients each were created. Pain severity (P = 0.019) and activity limitation (P = 0.001) during hospitalisation were higher in the M-RATS group. However, no significant differences existed post-discharge in pain (P = 0.383), cough (P = 0.677), shortness of breath (P = 0.526), disturbed sleep (P = 0.525), drowsiness (P = 0.304), fatigue (P = 0.153), distress (P = 0.893), walking difficulty (P = 0.242), or activity limitation (P = 0.513). M-RATS caused less intraoperative blood loss (P = 0.013), more stations of dissected lymph nodes (P = 0.001), more numbers of dissected lymph nodes (P = 0.001), and less tube drainage on the first postoperative day (P = 0.003) than U-VATS. CONCLUSION: M-RATS and U-VATS achieved comparable symptom burden and functional impairment after discharge. However, compared to U-VATS, M-RATS was associated with more severe pain and activity limitation in the short postoperative period. TRIAL REGISTRATION NUMBER: ChiCTR2000033016.
RESUMO
Objective Current transnasal endoscopic techniques for sinus and skull base surgery use a single endoscope to provide visualization from one perspective curtailing depth perception and compromising visualization of the instrument-target interface. The view can be blocked by instruments, and collisions between instruments often occur. The objective of this study was to investigate the use of multiportal retrograde endoscopy to provide more accurate manipulation of the surgical target. Design Maxillary antrostomy and frontal sinusotomy were performed on three different cadavers by three different surgeons. A zero-degree rigid endoscope was introduced through the nose for the standard transnasal approach. A flexible endoscope was introduced transorally, directed past the palate superiorly, and then flexed 180 degrees for the retrograde view. Videos of the standard transnasal view from the rigid endoscope and retrograde view from the flexible endoscope were recorded simultaneously. Results All surgeries were able to be performed with dual-screen viewing of the standard and retrograde view. The surgeons noted that they utilized the retrograde view to adjust the location of ends/tips of their instruments. Four surgeons reviewed the videos and individually agreed that the visualization achieved provided a perspective otherwise not attainable with rigid transnasal endoscopy alone. Conclusion High-quality visualization of surgical targets such as the frontal or maxillary ostia can be challenging with rigid endoscopes alone. Multiportal retrograde endoscopy provides proof of concept that additional views of a surgical target can be achieved. Additional work is needed to further develop indications, techniques, and generalizability to targets beyond those investigated here.
RESUMO
Objective: To compare the uniportal and multiportal video-assisted thoracoscopic surgery (VATS) in patients with non-small-cell lung cancer (NSCLC). Methods: Medical records of 128 patients with NSCLC who underwent surgical treatment in the First School of Clinical Medicine, Southern Medical University from August 2020 to February 2022 were retrospectively analyzed. There were 60 patients who underwent uniportal VATS (UVATS group) and 68 patients underwent multiportal VATS (MVATS group). The relevant indexes, complications, postoperative pain levels and quality of life, recurrence, metastases and survival between the two groups were compared. Results: UVATS was associated with longer operation time and higher intraoperative blood loss compared to MVATS (P<0.05). The postoperative drainage volume, and the visual analogue scale (VAS) scores at 24 and 72 hours were lower in the UVATS group compared to the MVATS group, while the chest tube retention time and hospitalization time were shorter than those in the MVATS group (P<0.05). The quality of life at six months after surgery in the UVATS group was significantly higher than that in the MVATS group (P<0.05). Conclusions: UVATS and MVATS have similar outcomes in patients with NSCLC. Although UVATS surgery takes longer and is associated with more interoperative bleeding, it can reduce postoperative pain, shorten postoperative recovery time, and help further improve the quality of life of patients after surgery.
RESUMO
The endoscopic contralateral transmaxillary (CTM) approach has been proposed as a potential route to widen the corridor posterolateral to the internal carotid artery (ICA). In this study, we first refined the surgical technique of a combined multiportal endoscopic endonasal transclival (EETC) and CTM approach to the petrous apex (PA) and petroclival synchondrosis (PCS) in the dissection laboratory, and then validated its applications in a preliminary surgical series. The combined EETC and CTM approach was performed on three cadaver specimens based on four surgical steps: (1) the nasal, (2) the clival, (3) the maxillary and (4) the petrosal phases. The CTM provided a "head-on trajectory" to the PA and PCS and a short distance to the surgical field considerably furthering surgical maneuverability. The best operative set-up was achieved by introducing angled optics via the endonasal route and operative instruments via the transmaxillary corridor exploiting the advantages of a non-coaxial multiportal surgery. Clinical applications of the combined EETC and CTM approach were reported in three cases, a clival chordoma and two giant pituitary adenomas. The present translational study explores the safety and feasibility of a combined multiportal EETC and CTM approach to access the petroclival region though different corridors.
RESUMO
The transorbital approach (TOA) is gaining popularity in skull base surgery scenarios. This approach represents a valuable surgical corridor to access various compartments and safely address several intracranial pathologies, both intradurally and extradurally, including tumors of the olfactory groove in the anterior cranial fossa (ACF), cavernous sinus in the middle cranial fossa (MCF), and the cerebellopontine angle in the posterior cranial fossa (PCF). The TOA exists in many variants, both from the point of view of invasiveness and from that of the entry point to the orbit, corresponding to the four orbital quadrants: the superior eyelid crease (SLC), the precaruncular (PC), the lateral retrocanthal (LRC), and the preseptal lower eyelid (PS). Moreover, multiportal variants, consisting of the combination of the transorbital approach with others, exist and are relevant to reach peculiar surgical territories. The significance of the TOA in neurosurgery, coupled with the dearth of thorough studies assessing its various applications and adaptations, underscores the necessity for this research. This extensive review delineates the multitude of target lesions reachable through the transorbital route, categorizing them based on surgical complexity. Furthermore, it provides an overview of the different transorbital variations, both standalone and in conjunction with other techniques. By offering a comprehensive understanding, this study aims to enhance awareness and knowledge regarding the current utility of the transorbital approach in neurosurgery. Additionally, it aims to steer future investigations toward deeper exploration, refinement, and exploration of additional perspectives concerning this surgical method.
RESUMO
The treatment of pathologies located within and surrounding the orbit poses considerable surgical challenges, due to the intricate presence of critical neurovascular structures in such deep, confined spaces. Historically, transcranial and craniofacial approaches have been widely employed to deal with orbital pathologies. However, recent decades have witnessed the emergence of minimally invasive techniques aimed at reducing morbidity. Among these techniques are the endoscopic endonasal approach and the subsequently developed endoscopic transorbital approach (ETOA), encompassing both endonasal and transpalpebral approaches. These innovative methods not only facilitate the management of intraorbital lesions but also offer access to deep-seated lesions within the anterior, middle, and posterior cranial fossa via specific transorbital and endonasal corridors. Contemporary research indicates that ETOAs have demonstrated exceptional outcomes in terms of morbidity rates, cosmetic results, and complication rates. This study aims to provide a comprehensive description of endoscopic-assisted techniques that enable a 360° access to the orbit and its surrounding regions. The investigation will delve into indications, advantages, and limitations associated with different approaches, while also drawing comparisons between endoscopic approaches and traditional microsurgical transcranial approaches.

This study aims to compare the perioperative outcomes and long-term survival of U-VATS lobectomy for NSCLC with multiportal VATS (M-VATS, involving two ports or more) lobectomy. A total of 339 patients who underwent intentional VATS lobectomy for lung cancer between 2012 and 2017 were included in the analysis. Perioperative outcomes and long-term survival were evaluated. Propensity score matching was utilized to minimize baseline characteristic differences between the two groups. Out of the total cases, 17 (5.01%) were converted to open thoracotomy. The conversion rates were 4.96% (7/141) in the U-VATS group and 5.05% (10/198) in the M-VATS group. A total of 322 consecutive patients underwent VATS lobectomy and mediastinal lymphadenectomy. After propensity matching, 106 pairs were obtained, consisting of 83 males and 129 females. Intraoperative bleeding volume, number of retrieved lymph nodes, explored nodal stations, drainage time and volume, and postoperative hospital stay were similar between the two groups. Both groups exhibited comparable morbidity and mortality rates. From the multivariable analysis, there was no significant difference observed in terms of overall survival (OS) and disease-free survival (DFS) between the two patient cohorts. U-VATS demonstrated comparable perioperative outcomes and long-term efficacy to M-VATS. However, further confirmation of these findings is required.

BACKGROUND: Sphenoorbital meningiomas (SOM) harbor intrinsic features that render their surgical management and the reconstruction of the resulting bony defect overtly challenging. METHODS: A 70-year-old woman, harboring a long-standing left frontotemporal bony swelling conservatively managed, presented with progressive left proptosis. Radiological features were consistent with an en plaque SOM. A one-step multiportal transcranial and endoscopic transorbital approach (TOA) with custom bone three-dimensional (3D) printing reconstruction using polymethylmethacrylate (PMMA) was scheduled. RESULTS: Postoperative functional and aesthetic results were excellent, with proptosis and calvarian deformity resolution. Tumor subtotal resection was achieved. Histopathological diagnosis confirmed a transitional meningioma (WHO grade I). CONCLUSIONS: The endoscopic TOA, isolated or as part of a multiportal strategy, has entered the surgical armamentarium for the treatment of SOMs. A customized PMMA cranioplasty can be considered a possible option for the reconstruction of large bony defects in a one-step fashion.

BACKGROUND: The relationship between quality of life at three months after lung cancer surgery and different surgical approaches is remains unclear. This study aimed to compare the quality of life of patients three months after uniportal and multiportal thoracoscopic lobectomy. METHODS: Data from patients who underwent lung surgery at the Department of Thoracic Surgery, Sichuan Cancer Hospital between April 2021 and October 2021 were collected. The European Organization for Research and Treatment of Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and Quality of Life Questionnaire-Lung Cancer 29 (EORTC QLQ-LC29) were used to collect quality of life data of the patients. Potential confounding factors in the baseline data were included in a multivariate regression model for adjustment, and the quality of life of the two groups three months postoperatively was compared with traditional clinical outcomes. RESULTS: A total of 130 lung cancer patients were included, with 57 males (43.8%) and 73 females (56.2%), and an average age of (57.1±9.5) yr. In the baseline data of the two groups, there was a statistical difference in the number of chest drainage tubes placed (P<0.001). After adjustment with the regression model, at three months postoperatively, there were no significant differences in all symptoms and functional status scores between the two groups (all P>0.05). The multiportal group had longer surgery time (120.0 min vs 85.0 min, P=0.001), postoperative hospital stay (6.0 d vs 4.0 d, P=0.020), and a higher incidence of early ≥ grade 2 complications (39.0% vs 10.1%, P=0.011) compared to the uniportal group. CONCLUSIONS: Patients undergoing uniportal and multiportal thoracoscopic lobectomy have similar quality of life at three months postoperatively. The uniportal group may have certain advantages in terms of traditional clinical outcome indicators such as operation time, postoperative hospital stay, and early postoperative complications.

Background: Uniportal video-assisted thoracoscopic surgery (VATS) segmentectomy is gaining worldwide acceptance, but experience in North America is still limited. We report a North American multicenter comparison of uniportal vs. multiportal VATS segmentectomy. Methods: We performed an institutional review board-exempt retrospective chart review on prospectively collected databases at two North American centers, from January 2012 to December 2020. We included all VATS segmentectomy patients and excluded emergent cases (n=1), patients with incomplete records (n=2), and segmentectomy performed in conjunction with another type of lung resection (n=1). We recorded patient demographics, perioperative data, 30-day postoperative complications and compared outcomes between cohorts. We provided descriptive statistics for each group. We calculated propensity score matching and paired patients 1:1. We defined P values less than 0.05 as statistically significant. Results: We performed a total of 423 VATS segmentectomies, 181 uniportal (42.7%) vs. 242 multiportal (57.2%). Indications for surgery were primary lung cancer (n=339), metastatic (n=41), benign disease (n=40), and other (n=3). We staged 85.1% of patients preoperatively with positron emission tomography-computed tomography (PET-CT) scan according to National Comprehensive Cancer Network (NCCN) guidelines. Propensity score matching generated 156 patients on each group. Operating time was significantly lower in the uniportal group compared to multiportal (130 vs. 161 min respectively, P<0.001). We found no difference in estimated blood loss, Clavien-Dindo class III-IV complications, conversion to thoracotomy, R0 resection rate, nodal upstaging, hospital length of stay, 30-day readmission or mortality. Conclusions: Our experience from two North American centers indicates that, in experienced hands, postoperative outcomes after uniportal and multiportal VATS segmentectomy are comparable.
RESUMO
It remains controversial whether one-port video-assisted thoracoscopic surgery (VATS) or multiportal VATS is better for segmentectomy in patients with early non-small cell lung cancer (NSCLC). We conducted this meta-analysis of eight published studies to compare the clinical effectiveness and safety of the two surgical approaches. The uniportal group had a shorter postoperative hospital stay (mean difference (MD): - 0.40, 95% CI [- 0.71 to - 0.08] days, p = 0.01), lower postoperative pain scores on day 3 (MD: - 0.90, 95% CI [- 1.26 to - 0.54], p < 0.00001) and day 7 (MD: - 0.33, 95% CI [- 0.62 to - 0.04], p = 0.02), fewer days of chest tube drainage (MD: - 0.47, 95% CI [- 0.78 to - 0.15] days, p = 0.004), and a smaller wound (MD: - 0.73, 95% CI [- 1.00 to - 0.46] cm, p < 0.00001) than the multiportal group. However, there were no significant differences between the groups in complications, operative times, resected lymph nodes, resected lymph node stations, blood loss, postoperative pain scores on days 1, 2, 30, overall survival (OS), or disease-free survival (DFS). The most common complications were prolonged air leakage (10.29%), bleeding (8.82%), vascular injury (7.14%), empyema (5.88%), and arrhythmia (5.26%) in the uniportal group. Overall, uniportal VATS appears to be better than multiportal VATS for segmentectomy in patients with NSCLC, with better postoperative outcomes and similar survival rates.

Non-small cell lung cancer (NSCLC) is the most typical type of lung cancer, and it is the leading cancer-related mortality globally. Lobectomy for early-stage NSCLC has been characterized in the previous decade using a wide range of methodologies. The development of video-assisted thoracoscopic surgery (VATS) allowed surgeons first to reduce the thoracotomy size, which is generally anterior, limiting it to trocar incisions or a single portal approach. This review aimed to describe current perspectives on operative outcomes, lymph node removal, oncologic outcomes, and advantages for surgeons performing uniportal VATS (uVATS) and multiportal (mVATS) lobectomy. The advantages of uVATS include comfortable operating for surgeons with a direct view and safety, and for patients more favourable operative outcomes. Also, the uVATS approach has previously been demonstrated to be effective and safe, with positive outcomes not just with respect to cosmetics but also in terms of a speedy recovery. Oncological uVATS clearance is comparable to multiportal VATS with respect to early mid-term survivability as well as nodal staging, as per retrospective comparison studies. However, the interpretation of outcomes must be made cautiously due to selection bias as well as lack of long-term follow-up; the choice of which VATS approach to utilize for patients' treatment following pulmonary resection is largely based on the preferences of the surgeon. As a result, it is difficult to say if one VATS method is better than another.
RESUMO
Transorbital approaches are genuinely versatile surgical routes which show interesting potentials in skull base surgery. Given their "new" trajectory, they can be a very useful adjunct to traditional routes, even being a valid alternative to them in some cases, and add valuable opportunities in selected patients. Indications are constantly expanding, and currently include selected intraorbital, skull base and even intra-axial lesions, both benign and malignant. Given their relatively recent development and thus unfamiliarity among the skull base community, achieving adequate proficiency needs not only a personalized training and knowledge but also, above all, an adequate case volume and a dedicated setting. Current, but mostly future, applications should be selected by genetic, omics and biological features and applied in the context of a truly multidisciplinary environment.
RESUMO
BACKGROUND: To evaluate the safety and efficacy of single incision plus one (SI+1) port three-dimensional (3D) laparoscopic minimally invasive esophagectomy (MIE). METHODS: Clinical data of patients who underwent 3D thoracic laparoscopic MIE in our department from September 2020 to March 2021 were analyzed retrospectively. According to the different methods of laparoscopic surgery, the patients were divided into 2 groups: SI+1 port 3D laparoscopy group and multiportal 3D laparoscopy group. The operation time of the 3D laparoscopy component, amount of intraoperative blood loss, number of celiac lymph node dissections, postoperative abdominal drainage days, postoperative total abdominal drainage, postoperative complications, and length of hospital stay were analyzed. RESULTS: There was no significant difference between the 2 methods in laparoscopic operation time (30.11±5.86 vs. 28.45±4.72 min, P=0.49), intraoperative blood loss (34.44±9.82 vs. 35.91±6.25 mL, P=0.69), number of celiac lymph node dissections (8.44±3.13 vs. 7.09±2.12, P=0.27), postoperative abdominal drainage days (3.11±0.33 vs. 3.00±0.00 days, P=0.28), postoperative total abdominal drainage (95.00±23.33 vs. 92.27±11.26 mL, P=0.74), postoperative complications (22.2% vs. 27.3%, P=0.33), and hospital stay (9.67±0.71 vs. 10.18±0.87 days, P=0.17). None of the patients enrolled in the study had recurrence or death to date. CONCLUSIONS: The application of SI+1 port 3D laparoscopy in minimally invasive resection of esophageal carcinoma is safe and feasible.
RESUMO
BACKGROUND: In some institutions, a recently introduced uniportal approach has replaced the multiportal approach for thoracoscopic major pulmonary resection. This study investigated the effect of this change on the surgical learning curve by examining the perioperative results of a single surgeon. METHODS: Between April 2012 and August 2020, 376 patients with primary lung cancer underwent thoracoscopic lobectomy with ND2a-1/2 lymphadenectomy in the authors' hospital. Surgery was performed by one of the authors in 189 of these patients, who were thus enrolled in this retrospective study. The surgeries were classified chronologically into five phases and the operative time, rate of intraoperative massive bleeding, and rate of postoperative prolonged air leak (PAL) were then compared. The learning curve (i.e., operative time) was assessed by Spearman's rank correlation test. The perioperative results achieved with the uniportal and multiportal approaches were also compared before and after the patients were matched for their characteristics based on the propensity score. RESULTS: The five phases differed significantly with respect to the operative time and rate of postoperative PAL (P<0.0001, P=0.0061). The correlation between operative time and number of consecutive cases was also significant (r=-0.579, P<0.0001). Superior results in terms of operative time (P<0.0001), duration of postoperative drainage (P<0.0001), and rate of postoperative PAL (P=0.0034) were obtained using a uniportal rather than multiportal approach. CONCLUSIONS: The transition from a multiportal to a uniportal approach did not cause a decline in the learning curve of thoracoscopic lobectomy with ND2a-1/2 lymphadenectomy.
RESUMO
In recent decades, the ever-expanding use of endoscopes and development of dedicated instrumentation have reshaped the panorama of surgical approaches to the frontal sinus.1 Nonetheless, the far lateral portion of the sinus might still represent a concern, especially in cases with unfavorable or distorted anatomy.2,3 We report the case of a 52-year-old man, referred to our department for recurrent episodes of left orbital swelling and supraorbital headache, 3 months after Draf III frontal sinusotomy for marsupialization of multiple frontal mucoceles. Computed tomography and magnetic resonance imaging scans were consistent with persistent inflammatory tissue in the far lateral left frontal sinus. Revision surgery was performed, adopting a combined endonasal orbital transposition3 and superior eyelid transorbital approach.4,5 The postoperative course was uneventful, and the microbiologic and histologic examinations demonstrated noninvasive Aspergillus fumigatus infection. The radiologic control showed patency of the frontal recess and complete clearance of the sinus. The patient is asymptomatic after 16 months (Video 1). The transorbital approach is effective in managing orbital and frontal sinus diseases,6 and the combination with the endonasal route grants complete access to the frontal sinus, even in cases of high pneumatization and lateral extension.4,7 Multiportal transorbital approaches represent additional techniques in the rhinologist's surgical armamentarium, which can overcome the limits of a single port approach.8,9 Reports on their use providing technical hints and critical considerations are to be encouraged to ease and stimulate the surgical training in this field.

PURPOSE: Uniportal video-assisted thoracoscopic surgery (VATS) complex segmentectomy has been challenging for thoracic surgeons. This study was designed to compare the perioperative outcomes between uniportal and multiportal VATS complex segmentectomy. METHODS: Data on a total of 122 uniportal and 57 multiportal VATS complex segmentectomies were assessed. Propensity score (PS) matching yielded 56 patients in each group. A crude comparison and PS matching analyses, incorporating preoperative variables, were conducted to elucidate the short-term outcomes between uniportal and multiportal VATS complex segmentectomies. RESULTS: The uniportal group had a significantly shorter operation time (173 min vs. 195 min, p = 0.004), pleural drainage duration (2.5 d vs. 3.5 d, p <0.001), and postoperative hospital stay (4.2 d vs. 5.3 d, p <0.001) before matching, and a significant difference was also observed after matching for pleural drainage duration (2.5 d vs. 3.6 d, p <0.001) and postoperative hospital stay (4.5 d vs. 5.2 d, p = 0.001). The numbers of dissected lymph nodes in N1 and N2 stations, the intraoperative and postoperative complication rates were not significantly different between these two groups. CONCLUSIONS: The uniportal VATS complex segmentectomy was not inferior to multiportal VATS in terms of perioperative outcomes and therefore should be considered as a viable surgical approach for treatment.

Endoscopic surgery of the orbit, periorbital region, and adjacent areas of the anterior and middle cranial fossae and brain has gained significant popularity over the last decade. These procedures are now being used at multiple institutions internationally with a success and safety record that has been demonstrated to be at par with or better than other techniques. The approaches provide minimally disruptive, scarless access to regions that previously required extensive open operations with significant retraction of critical neurovascular structures leading to prolonged morbidity and hospitalization. This paper will describe the basic techniques of these approaches, how they can be used alone or in multiportal (para- and contraportal) technique and guide the reader to resources for further learning.
RESUMO
OBJECTIVE: Over the years, Meckel's cave pathologies have been judged off-limits because of high rates of morbidity. Even though several studies have defined various surgical routes with tolerable morbidity and mortality rates, controversies related to the optimal avenue to treat different categories of Meckel's cave and cavernous sinus neoplasms persist. With unceasing energy to cultivate minimally invasive neurosurgical approaches, the endoscopic endonasal route has been tested, and the approach effectively performed, to provide a valid surgical window to these areas. In this dynamic and challenging scenario, another ventral endoscopic minimally invasive route-that is, the superior eyelid endoscopic transorbital approach-has been very recently proposed, and used in selected cases, to access the cavernous sinus and Meckel's cave regions. METHODS: The authors report the technical nuances of a combined and simultaneous endoscopic endonasal and transorbital surgical treatment of a patient with a Meckel's cave schwannoma. The operation involved collaboration among neurosurgery, otorhinolaryngology, and ophthalmology (oculoplastic surgery). The patient recovered well, had no neurological deficits, and was discharged to home 3 days after surgery. RESULTS: The multiportal combined route was proposed for the following reasons. The endonasal approach, considered to be more familiar to our skull base team, could allow control of possible damage of the internal carotid artery. From the endonasal perspective, the most inferior and medial portion of the tumor could be properly managed. Finally, the transorbital route, by means of opening the lateral wall of the cavernous sinus via the meningoorbital band, could allow control of the superolateral part of the tumor and, most importantly, could permit removal of the portion entering the posterior cranial fossa via the trigeminal pore. Simultaneous surgery with two surgical teams working together was planned in order to reduce operative time, hospital stay, and patient stress and discomfort, and to ensure "one-shot" complete tumor removal, with minimal or no complications. CONCLUSIONS: This study represents the translation into the real surgical setting of recent anatomical contributions related to the novel endoscopic transorbital approach and its simultaneous integration with the endoscopic endonasal pathway. Accordingly, it may pave the way for future applications related to minimally invasive, multiportal endoscopic surgery for skull base tumors.
