Endoscopic endonasal approach for clipping of a PICA aneurysm
Authors: Goldschmidt Ezequiel , Lavigne Philippe , Snyderman Carl , Gardner Paul A. 
Published: April 2020

This video depicts the case of a 59-year-old woman that presented to the emergency department with the worst headache of her life. CT showed subarachnoid hemorrhage and digital subtraction angiogram demonstrated a right-side posterior inferior cerebellar artery (PICA) aneurysm. Given the medial and ventral position of the aneurysm, deep to the lower cranial nerves, which obviated distal control from an open approach, and the absence of an endovascular option able to reliably preserve the PICA, an endonasal approach was offered. A far medial approach was performed, and the aneurysm was successfully clipped. The patient developed a postoperative CSF leak with persistent posthemorrhagic hydrocephalus treated with reexploration and an eventual ventriculoperitoneal shunt. The patient was discharged without neurological deficits.The video can be found here: https://youtu.be/_9hsM2CaMow.

Published: April 2020

Atypical trigeminal schwannomas (ATSs) are notorious for their ability to invade the skull base. An expanded endoscopic endonasal approach (eEEA) provides direct access to the tumor with no need for cerebral retraction or manipulation of neurovascular structures. Herein, we present a case of a large temporal fossa extradural lesion with secondary invasion of the sella, clivus, and temporal and infratemporal fossae in a 49-year-old male with severe vision loss. A transpterygoid transmaxillary approach was performed. Gross-total removal was achieved and pathology revealed the diagnosis of ATS. Visual function fully recovered in the right side and the patient has been uneventfully followed since surgery.The video can be found here: https://youtu.be/6pSwdYsN9hk.

Authors: Sarris Christina E. , Santarelli Griffin D. , Little Andrew S. 
Published: April 2020

This video demonstrates the transorbital approach for endoscopic repair of an anterior skull base encephalocele. The patient is a 77-year-old man with morbid obesity and a 2-year history of left-sided cerebrospinal fluid (CSF) rhinorrhea and radiographic evidence of an anterior skull base defect with an encephalocele. An endoscopic transorbital approach was chosen for repair because of its minimally invasive access to the anterolateral skull base. The patient had an excellent clinical outcome with resolution of the CSF rhinorrhea and preservation of full vision and extraocular muscle function.The video can be found here: https://youtu.be/oDhZgnaiZ00.

Authors: Joyce Evan , Karsy Michael , Makarenko Serge , Oakley Gretchen M. , Couldwell William T. 
Published: April 2020

Anterior skull base approaches have included endoscopic or open microsurgical approaches for intracranial pathologies. However, discussion of a combined hybrid, cranioendoscopic approach, leveraging the benefits of both techniques, has been limited. Here we describe a case of a combined endoscopic, endonasal, and open microsurgical frontotemporal approach for resection of a complex anterior skull base lesion. A 62-year-old man with a large meningioma extending intradurally through the cribiform plate and sphenoethmoidal sinuses underwent a cranioendoscopic resection. Surgical techniques, including repair of the anterior skull base defect as well as complication avoidance and the coordination of multiple surgeons, are discussed.The video can be found here: https://youtu.be/Ti9tUUdWgJc.
Hemorrhagic direct traumatic carotid-cavernous fistula during endoscopic transsphenoidal surgery: intraoperative management and endovascular treatment
Authors: Cossu Giulia , Atkins Tyler , Hajdu Steven D. , Puccinelli Francesco , Daniel Roy T. , Messerer Mahmoud 
Published: April 2020

Carotid-cavernous fistula (CCF) is a rare complication after transsphenoidal surgery with only 10 cases published (Ahuja et al., 1992; Cinar et al., 2013; Cossu et al., 2020; Dolenc et al., 1999; Kalia et al., 2009; Karaman et al., 2009; Kocer et al., 2002; Koitschev et al., 2006; Pigott et al., 1989; Takahashi et al., 1969). Intraoperative findings vary from unrecognized events to life-threatening hemorrhages.We provide a description of the management of an acute CCF occurring during sphenoidotomy in a patient with pituitary apoplexy. Osteotomy performed in the rostrum resulted in a fracture, which extended toward the intracavernous carotid artery.Bleeding was managed with mechanical compression. Endovascular treatment allowed closure of the fistula through transarterial coiling and glue. Arterial patency was preserved and the patient had no new neurological deficit.Drilling should be considered over osteotomy for the anterior sphenoidotomy.The video can be found here: https://youtu.be/0Me23xIVeNI.

Published: April 2020

Chordomas are rare tumors that occur at an incidence rate of 0.8 per 100,000. Thirty-five percent of chordomas occur in the spheno-occipital region. We present a case of a clival chordoma that had severe brainstem compression. The patient had a 1-year history of slurred speech and left facial weakness (House-Brackmann 3). The endoscopic endonasal transclival approach gave a panoramic view of the region without the necessity of brain retraction or manipulation of the surrounding cranial nerves. Gross-total resection was achieved and no CSF leak was encountered postoperatively. The left facial weakness improved to House-Brackmann 1.The video can be found here: https://youtu.be/DzW9Q6ckTHw.

Authors: Lan Ming-Ying , Wang Wei-Hsin 
Published: April 2020

This is a 37-year-old woman who presented with weight gain, a moon-shaped face, and muscle weakness for 4 months. Cushing’s disease was confirmed after a series of diagnostic tests. MRI demonstrated a pituitary macroadenoma with right cavernous sinus invasion and encasement of the right ICA. An endoscopic endonasal approach was performed, and gross-total resection could be achieved without injury of the cranial nerves. The Cushing’s syndrome improved gradually after the surgery. Histopathology revealed a corticotroph adenoma. In this surgical video, we demonstrate the strategies of tumor resection according to a surgical anatomy-based classification of the cavernous sinus from an endonasal perspective.The video can be found here: https://youtu.be/aNXFRdGfjpI.
Combined strategy of maximal endoscopic endonasal resection and early radiation therapy for complex cystic and solid craniopharyngioma: operative video
Authors: Liu James K. , Zhao Kevin , Eloy Jean Anderson 
Published: April 2020

Craniopharyngioma is a rare and benign intracranial tumor of the sellar and suprasellar region. Historically, these tumors were mostly accessed through transcranial corridors and resected with microsurgical techniques. Endoscopic endonasal surgery has recently gained popularity in the treatment of these tumors and has shown at least comparable results to transcranial approaches. The endoscopic endonasal approach provides direct midline access through a transplanum transtuberculum corridor and gives excellent visualization of the undersurface of the optic chiasm to allow safe bimanual sharp dissection of the tumor from the hypothalamus. In this operative video, we demonstrate the case of a 56-year-old female who had a complex craniopharyngioma with solid and cystic components extending superolaterally into the right frontal lobe. This lesion was invasive and partially encased the right optic nerve, optic chiasm, and anterior communicating artery complex. Although a traditional transcranial approach could have been utilized, we elected for an endoscopic endonasal approach for a maximal safe near-total resection, preserving the neurovascular structures. The patient underwent radiation therapy with favorable regression of the residual tumor on subsequent imaging studies. This case illustrates the feasibility of a combined strategy of maximal safe endoscopic endonasal resection followed by early radiation therapy for a complex, invasive cystic and solid craniopharyngioma. The technical nuances of safe bimanual microsurgical dissection of tumor adhesions off of critical neurovascular structures are demonstrated.The video can be found here: https://youtu.be/z0AINLpRZGs.
Combined endoscopic endonasal and sublabial transmaxillary approach for resection of giant infratemporal fossa schwannoma with intracranial extension: operative video and technical nuances
Authors: Liu James K. , Zhao Kevin , Vazquez Alejandro , Eloy Jean Anderson 
Published: April 2020

Tumors of the infratemporal fossa (ITF) are surgically formidable lesions due to their deep location and proximity to critical neurovascular structures. Selecting the optimal surgical corridor for a giant ITF lesion with extensive medial and lateral extension can be challenging due to the limited surgical freedom offered by each individual approach. In this operative video, we demonstrate a case of a 44-year-old female with a giant ITF schwannoma with intracranial extension and erosion of the central skull base. Although we considered several surgical approaches, including a standard binostril endoscopic endonasal approach and an endoscopic Denker’s approach, we eventually chose a combined endoscopic endonasal and sublabial (Caldwell-Luc) transmaxillary approach. This combined approach provides significantly greater surgical freedom than a pure endonasal route to the lateral ITF. The sublabial Caldwell-Luc corridor provides a more direct “head-on” trajectory to the target of the lateral ITF than the pure endonasal route. This combined approach provides a multiportal, multicorridor access, allowing for more surgical freedom and preservation of the piriform aperture and nasolacrimal duct. This case illustrates the versatility of the combined endoscopic endonasal and sublabial transmaxillary approach for giant ITF tumors with significant lateral extension. The technical nuances and surgical concepts are demonstrated in this operative video manuscript.The video can be found here: https://youtu.be/gy-pkjLdDgE.

Published: April 2020

Petroclival chondrosarcomas are a formidable surgical challenge given the close relationship to critical neurovascular structures. The endoscopic endonasal approach can be utilized for many petroclival chondrosarcomas. However, tumors that extend to the inferior petrous apex require working behind the internal carotid artery (ICA). We present a case of a 33-year-old with a 1-year history of complete abducens palsy, with imaging showing an enhancing mass centered at the left petroclival fissure and inferior petrous apex behind the paraclival carotid artery and extending down into the nasopharynx abutting the cervical ICA. In this video, we describe the surgical steps of the endoscopic endonasal translacerum approach with ICA skeletonization and mobilization. We also highlight the relevant surgical anatomy with anatomical dissections to supplement the surgical video. The patient did well without complications. Postoperative MRI demonstrated complete resection and pathology revealed grade II chondrosarcoma. He underwent adjuvant proton beam radiotherapy.The video can be found here: https://youtu.be/80QXALJW9ME.
Endoscopic endonasal surgery for giant pediatric craniopharyngioma

Published: April 2020

Pediatric craniopharyngiomas that were once thought to be inoperable or considered only for salvage medical therapy are now being reconsidered for aggressive surgical resection via endoscopic endonasal approaches. Here we review the operative video case of an 11-year-old with a giant complex craniopharyngioma that was resected via an endoscopic endonasal approach. Due to the extent of tumor burden near the basilar apex, a transclival approach was necessary. To accomplish this, a wide sphenoidotomy, posterior ethmoidectomy, and resection of the middle turbinate were necessary to create enough working space for the resection. We also highlight several key innovations in pediatric endoscopic endonasal surgery management and underscore a multidisciplinary approach that allows for the safe and successful treatment of these lesions. Our multidisciplinary team involves an experienced fellowship-trained endoscopic skull base surgeon and otolaryngologist, as well as a pediatric neurosurgeon, pediatric endocrinologist, pediatric anesthesiologist, and pediatric intensivists who play important roles in the preoperative, intraoperative, and postoperative phases of care of the patient. Finally, we discuss critical surgical decision points including pituitary transposition, which has a lot of conceptual appeal when it is anatomically feasible but unfortunately, in our experience, has low functional preservation rates. Initially, we always aim to utilize pituitary transposition for tuberoinfundibular craniopharyngiomas, and once the relationship between the tumor and the stalk is determined, a decision on whether to preserve or sacrifice the stalk and pituitary gland is made. In this particular case, there was a salvageable stalk and the transposition was performed knowing that the chances for functional preservation were low.The video can be found here: https://youtu.be/ClL73FU5QIU.
SINTESIS DAN KARAKTERISASI KOMPOSIT FIBER SABUT KELAPA SAWIT DENGAN RESIN EPOKSI
Authors: Setiawan Adhi 
Published: April 2020

The use of natural fiber as reinforcement for epoxy polymer composites is currently a concern for researchers because it is environmentally friendly so it can replace glass fiber or carbon in engineering applications. Palm fiber is a type of natural fiber that is produced by the cooking oil industry as a component of waste. The surface modification of fiber with NaOH solution is one of the factors that determines level of adhesion to the epoxy polymer matrix. This study to analyze the effect of alkali treatment on the morphology and characteristics of fiber. In addition, the effect of palm fiber composition on the mechanical properties of composites were studied. Alkali treatment on fiber was carried out using 10% wt sodium hidroxide solution. The morphology and characteristics palm fiber before and after alkali treatment were analyzed using SEM-EDX, XRD, and FTIR. Tensile tests were carried out on composites with treated fibers and without treatment with sodium hidroxide solution. The results showed that alkali treatment caused the surface morphology of the fiber to be finer due to the loss of lignin and hemicellulose components. Alkali treatment fiber can increase the tensile strenght. Composites with fiber and resin composition of 4%: 96% wt that have undergone alkali treatment have a maximum tensile strength of 21.60 MPa.

This research was conducted in order to investigate the effects of time of planting on the grain yield and yield components of three advanced lines of rice under the Agro Ecological Zone (AEZ), Modhupur Tract. The research was conducted as a split plot using Randomized Complete Block Design (RCBD) with three replications in the Aman season of 2016 under the research field of Bangladesh Rice Research Institute (BRRI), Gazipur. In this research, the dates 01 August, 16 August, 31 August and 16 September were considered as the main factor in the main plots, and the advanced lines/varieties BR(Bio)9786-BC2-119-1-1, BR(Bio)9786- BC2-132-1-3 and BRRI dhan49 (check variety) were regarded as the secondary factors in the sub plots. The results showed that planting time significantly affected the plant height, the number of panicle per meter square, the number of tillers per meter square, the number of grains per panicle, 1000-grain weight and grain yield. Among the cultivars, the advanced line BR(Bio)9786-BC2-119-1-1 and BR(Bio)9786-BC2-132-1-3 produced significantly higher plant height, the number of panicle, the number of tillers, the number of grains per panicle, 1000- grain weight and grain yield than check variety BRRI dhan49 in all transplanting dates. The advanced line BR(Bio)9786-BC2-119-1-1 and BR(Bio)9786-BC2-132-1-3 produced average 1.02 and 0.57 t ha-1 higher yields respectively over the check variety BRRI dhan49 under the transplanting date 01 August to 31 August. The highest growth duration (130-146 days) was observed for the check variety BRRI dhan49 that followed by BR(Bio)9786-BC2-132-1-3 (132- 141 days) and BR(Bio)9786-BC2-119-1-1 (130-140 days)

Published: April 2020

The experiment was conducted in the Boro season of 2016-17, at Bangladesh Rice Research Institute (BRRI) farm under the Agro Ecological Zone (AEZ 28) Modhupur Tract. CN6 is a high spikelet bearing early maturing advanced line of rice but low in spikelet fertility. Supplemented nutrient management was examined to increase its spikelet fertility. Five treatments were used in this experiment. The treatments were as follows: T1 = BRRI recommended fertilizer dose + MgO @ 0.05%, T2 = BRRI recommended fertilizer dose + 60 g MoP + 60 g elemental S (80% wp) + 20 g ZnSO4, T3 = BRRI recommended fertilizer dose + Boron @ 5 ppm, T4 = BRRI recommended fertilizer dose + Copper @ 5 ppm) and T5 = BRRI recommended fertilizer dose alone. The experiment was conducted in Randomized Complete Block design with three replications. The results revealed that Treatment T3 (BRRI recommended fertilizer dose + Boron @ 5ppm) produced the more number of grains per panicle with an average of 201 which is 19.9% higher number of grains per panicle over the BRRI recommended fertilization under the treatment of T5. However, higher grain yield were recorded in treatment T3 compare to the control treatment T5 (BRRI recommended fertilization). Taken together, our results suggested that BRRI recommended fertilization alone with supplemented nutrient management, especially boron, significantly increased the spikelet fertility of the CN6 advanced line of Boro rice resulting higher yield.
