	<li>アルコール フリーの chlorexidine ソリューションで顔を殺菌します。キシロカインを希釈を含浸させた綿パッドと上がり前にきれいに消毒液鼻窩アドレナリン (1:1, 000, 000) の 1%。 注意: 局所麻酔と血管収縮に加え内視鏡的アプローチを有効に甲の中間の側面撤回を提供もこのウィッキングします。調節可能な保持アーム (特に中トルコ鞍相) 手術の特定のフェーズで使用される手術台に固定できます。ただし、いくつかの外科内視鏡外科分野のよりダイナミックなビューを修正することを好みます。これらのケースで彼らはどちらか両手で作業できるようにアシスタントに内視鏡を残すまたは彼らは彼ら自身の内視鏡を保持します。</li>
	<li>きれいに右腹部の象限と脂肪移植の術中の脳脊髄液 (CSF) 瘻の場合収穫の可能なサイトを表すので右ペリ臍地域の小さなウィンドウを残しながら腹部をおいましょう。 注: 麻酔科医に深い morphinic の鎮痛のための特別な注意を取る、プロシージャ、鼻粘膜の豊富な神経支配による出血を抑えるための鼻のフェーズでの平均血圧を制御します。</li>
</ol>3. 手術
注: 主に使用される鼻窩の側の選択は鼻によって決まりますが解剖学(隔偏差、メガ鼻甲介、ポリープ、以前の手術等)、水平 (横方向の拡張に対側アプローチ) 腫瘍の拡張機能、と腫瘍 (大きな腫瘍の binostril アプローチ) のサイズ。下垂体腺腫の大半は、一方的なアプローチで腫瘍とその拡張機能の良い露出を得るために十分です。
<ol><li>
鼻相
	<ol>
<li>内側下を識別し、甲を横方向に中央右の鼻および鼻の隔壁に、0 ° 短い硬性内視鏡 (長さ 18 cm 直径 4 mm) をご紹介します。隔偏差、異常や術前画像で検出された特定の腫瘍拡張の甲介の場合に、左の鼻孔アプローチを好みます。</li>
		<li>鼻腔内に入る他の機器に十分なスペースを提供するために鼻孔の優劣の面でいずれかの内視鏡の管を配置します。</li>
		<li>同側の蝶形骨口への幅広いアクセスを達成するために鈍いヘラで中央と優れた甲撤回横方向に優しく。取り消し操作中に骨折を避けるためにヘラで彼らの全体の長さを介して優れたおよび中間甲をサポートする注意してください。</li>
	</ol>
</li>
	<li>

	<ol>
<li>Nasoseptal 動脈からの出血を避けるためにモノポーラ蝶形骨 osteum と、choana の間で約 10-15 mm の垂直直線的に鼻粘膜を凝固 (の上縁で実行されている蝶口蓋動脈の枝、choana)。</li>
		<li>開いている、鼻中に対応する、骨の接触まで垂直方向に無愛想なヘラを使って凝固鼻粘膜が感じられます。</li>
		<li>鼻軟骨中隔との接合部まで前方鼻中をに従って、粘膜面のままに世話をしながら反対側の蝶形骨口を公開する左側にそれをプッシュします。</li>
		<li>公開し、蝶形骨吻骨鉗子と 1 つの口が切除を拡張する rongeur を削除します。蝶形骨洞のこの開口部には、exocranial 頭蓋骨底面の露出ことができます。</li>
		<li>トルコ鞍の開口部に干渉する場合、蝶形骨の粘膜を注意深く取り外します。</li>
		<li>トルコ鞍の広い露出を提供する rongeurs と蝶形骨鼻中隔 (多くの場合複数の隔壁が存在) を削除します。</li>
		<li>術前の磁気共鳴画像 (MRI) および/または CT スキャン数とこれら septations; の方向を慎重に分析します。これは、関連する解剖学を認識することが重要です。これら septations のいくつかは頸動脈のプロミネンスに直接挿入ことがあります、したがって、(図 1図 2図 3図 4) 手術のこの段階では重要なランドマークとして識別される必要があります。 注: CT スキャンは 64 検出器行ベースのシステムを使用して実行されました。三次元再構成は、薄いスライス データの一連を使用して処理されました。MRI プロトコルは、3 テスラの撮像素子で実行されました。プロトコルに矢状 T1 強調グラディエント エコー シーケンス (MPRAGE) 造影とが含まれている、160 連続したスライス、1 mm 等方性ボクセル繰り返し時間 (TR) 2,300 ms エコー時間 (TE) 2.98 ms、視野のセグメンテーションのための基礎として 256 mm3 D の T2 のシーケンス。</li>
	</ol>
</li>
	<li>
トルコ鞍の相
	<ol>
<li>前方で正中線で斜凹部に優れたトルコ鞍を識別します。 注: 大規模なおよび/または侵襲的下垂体腫瘍、トルコ鞍底あります非常に薄いまたは完全に侵食されました。トルコ鞍の底は鞍結節部に対応するうつ病を前方と横方向に頸動脈プロミネンスによって制限 (C3 C5 セグメント)、optico 頸動脈凹部。</li>
		<li>頸動脈のプロミネンスの同定は横方向に, 5 mm 大きな骨カッターを調整したり、手術の終わりに位置を変更可能性があります骨フラップのヒンジでトルコ鞍底を開いた後。この時点で、拡大トルコ鞍骨切り横方向または前方骨 rongeurs と対象手術によると。 注: いくつかの外科医は、ダイヤモンド ドリルでトルコ鞍の底を開いて、小さな骨 rongeur と第二を開いて骨を拡大するを好むことがあります。この手順は、高速化できるし、拡張アプローチで一般的に使用されます。プロシージャの最後に骨を移動ことはできませんし、頚動脈への傷害を避けるために正中線でドリルには注意が必要があります。ニューロナビゲーションを使用して、手順をご案内します。</li>
		<li>細石刃を macroadenoma の正中線、または横偏側 microadenomas のケースとトルコ鞍の硬膜を開きます。に応じて、この硬膜開く横方向に拡張し、頚動脈への損傷を避けるために世話をします。</li>

Minimally Invasive Thumb-sized Pterional Craniotomy for Surgical Clip Ligation of Unruptured Anterior Circulation Aneurysms

Less invasive surgical approaches for intracranial aneurysm clipping may reduce length of hospital stay, surgical morbidity, treatment cost, and improve patient outcomes. We present our experience with a minimally invasive pterional approach for anterior circulation aneurysms performed in a major tertiary cerebrovascular center and compare the results with an aged matched dataset from the Nationwide Inpatient Sample (NIS). From August 2008 to December 2012, 22 elective aneurysm clippings on patients &#8804;55 years of age were performed by the same dual fellowship-trained cerebrovascular/endovascular neurosurgeon. One patient (4.5%) experienced transient post-operative complications. 18 of 22 patients returned for follow-up imaging and there were no recurrences through an average duration of 22 months. A search in the NIS database from 2008 to 2010, also for patients aged &#8804;55 years of age, yielded 1,341 hospitalizations for surgical clip ligation of unruptured cerebral aneurysms. Inpatient length of stay and hospital charges at our institution using the minimally invasive thumb-sized pterional technique were nearly half that of NIS (length of stay: 3.2 vs 5.7 days; hospital charges: $52,779 vs. $101,882). The minimally invasive thumb-sized pterional craniotomy allows good exposure of unruptured small and medium-sized supraclinoid anterior circulation aneurysms. Cerebrospinal fluid drainage from key subarachnoid cisterns and constant bimanual microsurgical techniques avoid the need for retractors which can cause contusions, localized venous infarctions, and post-operative cerebral edema at the retractor sites. Utilizing this set of techniques has afforded our patients with a shorter hospital stay at a lower cost compared to the national average.

Endoscopic Septoplasty with Limited Two-line Resection: Minimally Invasive Surgery for Septal Deviation

Endoscopic septoplasty is a surgical procedure in otolaryngology that is commonly performed to treat nasal airway obstruction caused by nasal septal deviation. It has a long history with multiple variations. In this article, a modified endoscopic septoplasty procedure using the limited two-line resection (2LoRs) technique at the posterior and inferior junction of the cartilaginous and bony septum is presented based on embryologic and anatomic knowledge of the nasal septum and the biomechanics of cartilaginous behavior. With this procedure, the quadrangular cartilage can be preserved as much as possible, which is helpful in retaining the supporting framework and rigidness of the septum. 2LoRs has been proven effective and sound for the correction of nasal septal deviation with rare complications. This modified procedure can be applied to correct the deviated nasal septum in the absence of any external nasal deformity to improve nasal patency or to improve access to the middle meatus or to the axillary region of the middle turbinate. It may also be used to expand the indications of septoplasty to children and adolescents because of its minimally invasive approach.

Endoscopic septoplasty is a time-honored surgical procedure with multiple variations. This paper focuses on a step-by-step surgical approach to perform a modified septoplasty procedure known as limited two-line resection. This surgical technique can be applied to correct a deviated nasal septum in the absence of an external nasal deformity.

An Endoscopic Transcanal Transpromontorial Approach for Vestibular Schwannomas using a Computer-Based Three-Dimensional Imaging System

A 2D monocular endoscope has been used in transcanal transpromontory vestibular schwannoma surgery instead of craniotomy. However, the absence of depth perception is the limitation of this approach. With the loss of depth perception, the surgeon will be not able to perform delicate and particularly complicated surgery. A binocular endoscope has been developed to provide stereoscopic vision with better depth perception for complicated anatomic structures and has been applied in some endoscopic surgeries. However, the diameter of the endoscope is a limitation in the performance of transcanal otologic surgeries. A small diameter endoscope facilitates easier surgery in a restricted space. A computer-based 3D imaging system can obtain 3D images in real-time using a small monocular endoscope. In this study, to evaluate the feasibility of a computer-based 3D imaging system for endoscopic lateral skull base surgery, we applied this 3D imaging system in a transcanal transpromontorial approach in two patients with vestibular schwannomas. The surgical procedure was completed without complication in these two cases. There was no mortality, perioperative complications, nor notable postoperative complications. Using this computer-based 3D imaging system, a better depth perception and stereoscopic vision was observed compared to a conventional 2D endoscope. The improvement in depth perception offers superior management of the complicated surgical anatomy.

Here, we present a transcanal transpromontorial approach for vestibular schwannomas using a computer-based three-dimensional (3D) imaging system combined with a two-dimensional (2D) endoscope. This system provided stereoscopic vision, better depth perception and reduced visual fatigue. This 3D imaging system enabled the application of 3D vision technology in endoscopic lateral skull base surgery.

Role of Diffusion MRI Tractography in Endoscopic Endonasal Skull Base Surgery

Endoscopic endonasal surgery has gained a prominent role in the management of complex skull base tumors. It allows the resection of a large group of benign and malignant lesions through a natural anatomical extra-cranial pathway, represented by the nasal cavities, avoiding brain retraction and neurovascular manipulation. This is reflected by the patients' prompt clinical recovery and the low risk of permanent neurological sequelae, representing the main caveat of conventional skull base surgery. This surgery must be tailored to each specific case, considering its features and relationship with surrounding neural structures, mostly based on preoperative neuroimaging. Advanced MRI techniques, such as tractography, have been rarely adopted in skull base surgery due to technical issues: lengthy and complicated processes to generate reliable reconstructions for inclusion in the neuronavigation system. 
This paper aims to present the protocol implemented in the institution and highlights the synergistic collaboration and teamwork between neurosurgeons and the neuroimaging team (neurologists, neuroradiologists, neuropsychologists, physicists, and bioengineers) with the final goal of selecting the optimal treatment for each patient, improving the surgical results and pursuing the advancement of personalized medicine in this field.

We present a protocol to integrate diffusion MRI tractography in patient work-up to endoscopic endonasal surgery for a skull base tumor. The methods for adopting these neuroimaging studies in the pre- and intra-operative phases are described.

Combined Endoscopic and Transoral Approach for Total Maxillectomy

The technique of maxillectomy has been revised since it was first described in the 1820s. During the past decade, the endoscopic approach has been widely practiced for resecting maxilla. Compared with the traditional approaches, the combined endoscopic and transoral approach has many advantages such as avoiding facial incisions and postoperative scars and better visualization of the surgical margin. However, this technique is complicated to master and possess several challenges. Here, we demonstrate this approach step-by-step to show how to perform a total maxillectomy. We also reported nine cases with malignant tumors originating from the maxilla, and for all of them total maxillectomy was performed with combined endoscopic and transoral approach. Our data showed that the combination of the endoscopic and transoral approach could be used to resect the total maxilla successfully, though the tumor extended to the infratemporal and pterygopalatine fossa should be treated very carefully to avoid its spread in the local area. Furthermore, besides denture, other reconstruction methods should be attempted to improve the postoperative quality of life after the total maxillectomy.

Endaural Endoscopic Atticoantrotomy (Retrograde Mastoidectomy) using a Constant Suction Bone-drilling Technique

Endoscopic middle ear surgery is a widely employed minimally invasive surgical technique to address middle ear and mastoid pathology. Bone drilling is the main technical challenge of endoscopic middle ear surgery. The accompanying video describes the detailed protocol of a constant-suction bone-drilling technique and the procedure of endaural exclusive endoscopic atticoantrotomy (retrograde mastoidectomy) using this technique. The main components of this bone-drilling technique include a soft and flexible suction tube, which is placed into the tympanic cavity to provide constant suction, and a soft sleeve, which is wrapped around the drill shaft to prevent the high-speed rotating shaft from damaging the lens of the endoscope. With these simple modifications, the traditional otological electrodrill can be used for drilling a tiny endaural incision in endoscopic middle ear surgery. Based on this bone-drilling technique, endaural endoscopic atticoantrotomy (retrograde mastoidectomy) can be successfully established for the removal of various amounts of bone, depending on the extent of the lesion. The short-term postoperative outcome seems promising.

The Microscopic Transcanal Approach in Stapes Surgery Revisited

The microscopic transcanal (aka transmeatal) surgical approach was first described in the 60s, offering a minimally invasive means of reaching the external auditory canal, the middle ear, and epitympanon. Such an approach avoids a retroauricular or endaural skin incision; however, working through a narrow space needs angled microsurgical instruments and specific training in otologic surgery. The transcanal approach restricts the working space; however, it offers a binocular microscopic vision into the middle ear without extended skin incisions and thus, reducing post-operative pain and bleeding. In addition, this minimally invasive approach avoids scar tissue complications, hypoesthesia of the auricle, and potential protrusion of the pinna. Despite its numerous advantages, this method is still not routinely performed by otologic surgeons. Since this minimally invasive technique is more challenging, there is a need for extensive training in order for it to be widely adopted by otologic surgeons. This article provides step-by-step surgical instructions for stapes surgery and reports possible indications, pitfalls, and limitations using this microscopic transcanal technique.

Full-Endoscopic Surgery for Hypothalamic Hamartoma Resection

Hypothalamic hamartomas (HH) are rare developmental anomalies of the inferior hypothalamus that often cause refractory epilepsy, including gelastic seizures. Surgical resection is an effective method to treat drug-resistant epilepsy and endocrinopathy in a suitable patient group. Open surgery, endoscopic surgery, ablative procedures, and stereotactic radiosurgery can be utilized. In this study, we aimed to describe the full-endoscopic approach for HH resection. The technique involves the use of an intraoperative ultrasonography (USG) system, a 30&#176; rigid endoscope system that has an outside diameter of 2.7 mm with two working channels, a stylet that has an outer diameter of 3.8 mm, a monopolar coagulation electrode, a fiberoptic light guide, and the endovision system. Microforceps and monopolar electrocautery are the two main surgical instruments for HH removal. The protocol is easy to apply after a particular learning curve has been passed and shorter than open surgical approaches. It leads to less blood loss. Full-endoscopic surgery for HH is a minimally invasive technique that can be applied safely and effectively with good seizure and endocrinological outcomes. It provides low surgical site pain and early mobilization.

Full-Endoscopic Interlaminar Approach for Decompression of Lateral Recess Stenosis

For lateral recess stenosis, extensive decompression with laminectomy is still performed in most centers. However, tissue-sparing surgeries are becoming more common. Full-endoscopic spinal surgeries have the advantages of being less invasive and offering a shorter recovery time. Here, we describe the technique of the full-endoscopic interlaminar approach for the decompression of lateral recess stenosis. The full-endoscopic interlaminar approach for the lateral recess stenosis procedure took approximately 51 min (range of 39-66 min). Blood loss could not be measured due to continuous irrigation. However, no drainage was required. There were no dura mater injuries reported in our institution. Furthermore, there were no injuries to the nerves, no cauda equine syndrome, and no hematoma formation. The patients were mobilized on the same day as surgery and discharged the next day. Therefore, the full-endoscopic technique for lateral recess stenosis decompression is a feasible procedure that lowers the operational time, complications, traumatization, and rehabilitation duration.

Technical advances and increased experience in full-endoscopic spinal surgeries enable these procedures to be performed with minimal incision, muscle retraction, and bone removal.
