Experience in surgical management of tumours involving the cavernous sinus.

Potential injury to the neurovascular structures within the cavernous sinus often prohibits aggressive removal of tumours involving it, however, fully understanding the anatomy and selecting an appropriate surgical approach can often resolve this problem with acceptable morbidity. Moreover, a tumour may originate from different anatomical structures of the cavernous sinus which will influence the difficulty and outcome of the surgery. In general, tumours in this region can be classified as intradural, intracavernous and invasive types. The strategy of surgical treatment varies among these different anatomical types. Therefore, preoperative evaluation of tumours in the cavernous sinus is critical for the selection of an appropriate microsurgical approach. During the past 5 years, 12 tumours involving the cavernous sinus have been operated upon which included four neuromas, three meningiomas, three cavernous haemangiomas, one plasmacytoma and one chondroma. Nine of these twelve tumours were totally resected after one or two operations. There was no surgical mortality and the most common morbidity was transient cranial nerve palsy. At 2 months after surgery there was no additional postoperative cranial nerve deficit in all the patients; however, one patient developed a postoperative middle cerebral artery infarct due to accidental injury to the internal carotid artery during surgery. The respectability of the tumour mostly depends on its consistency and the involvement of the adjacent anatomy. The pathoanatomical features of the tumours and the clinicoradiological findings, as well as the selection of the microsurgical approach, are discussed.     

Non-meningeal tumours of the cavernous sinus: a surgical analysis.

The popularisation of cavernous sinus approaches and subsequent experience has shaped our treatment paradigms for cavernous sinus meningiomas. However, pathologies in this region are diverse and each one requires individual consideration. The purpose of this study was first to analyse, define and summarise the individual characteristics of different non-meningeal tumours of the cavernous sinus and, secondly, to stress that their surgery can be accomplished with acceptable morbidity and rewarding results when those characteristics are considered. A retrospective analysis of 42 cases of benign non-meningeal tumours of the cavernous sinus operated on at Marmara University between April 1992 and April 2003 is presented. The patients were 15 males and 27 females aged 24-72 years. The study cohort consisted of 13 pituitary adenomas, 11 trigeminal schwannomas, seven chordomas, three chondrosarcomas, two juvenile angiofibromas, two epidermoid tumours, one plasmacytoma, one cavernous haemangioma and one internal carotid plexus schwannoma. The 42 patients underwent 46 operations aimed at radical surgical excision. Total resection was achieved in 50% and subtotal resection in 50% of cases. The majority of incompletely resected tumours were pituitary adenomas and chordomas, and 95% required further treatment. Twenty-nine percent of patients developed complications, namely cerebrospinal fluid fistula, haematoma, hydrocephalus, diabetes insipidus, cerebral infarction and cranial nerve palsies. Recurrence was seen in 7.1% of patients. At final follow up at an average of 48.2 months after surgery, the mean Karnofsky performance scale had risen from 83.4 to 87.4. Non-meningeal tumours of the cavernous sinus can be surgically resected with acceptable morbidity and mortality. In selected tumours the results are better than those for cavernous sinus meningiomas. The best surgical results are achieved with interdural tumours of the lateral sinus wall and the worst surgical results are seen in invasive tumours such as chordomas and pituitary adenomas. Individual tumour characteristics are presented in the text.     

前床突脑膜瘤的手术效果分析

目的探讨前床突脑膜瘤的手术效果以及影响肿瘤能否全切除的因素。方法回顾性分析1996年6月至2020年6月于海军军医大学附属长征医院神经外科行手术治疗的145例前床突脑膜瘤患者的临床资料。145例患者中,采用标准翼点入路84例,改良翼点入路46例,眶颧入路15例。通过Simpson分级评估肿瘤切除程度。通过单因素和多因素logistic回归分析方法探讨影响肿瘤切除程度的因素。通过临床随访评估症状的改善情况,行影像学随访评估肿瘤有无复发结果145例患者中,肿瘤全切除(Simpson Ⅰ~Ⅲ级)98例(67.6%),肿瘤部分切除(Simpson Ⅳ级)或单纯减压(Simpson Ⅴ级)47例(32.4%)。121例患者获随访,随汸时间为1~24(7.6±5.2)年术前视力下降的62例患者中,术后视力较术前改善32例(51.6%),无变化25例(40.3%),下降5例(8.1%)。随访期间肿瘤全切除患者的复发率为3.8%(3/78),未全切除患者的肿瘤复发或进展的比率为23.3%(10/43)。单因素分析结果表明,肿瘤的最大径、肿瘤对颈内动脉和海绵窦的侵袭程度及术前视力下降可能与肿瘤的切除程度有关(均P<0.05)。多因素logistic回归分析结果显示,肿瘤最大径(OR=3.21,95%CI:1.05~10.39,P<0.01)、肿瘤对颈内动脉及海绵窦的侵袭程度(OR=7.25,95%CI:2.35~21.64,P<0.01)为影响肿瘤全切除的独立危险因素,肿瘤最大径≤3 cm及肿瘤未完全包绕颈内动脉或未侵及海绵窦的患者手术全切除率较高,分别为74.8%(89/119)和82.8%(72/87)。结论对于前床突脑膜瘤,根据具体情况采用相应的手术策略,可获得较高的肿瘤全切除率,且复发率低。最大径<3 cm以及仅部分包绕颈内动脉或未侵及海绵窦的前床突脑膜瘤更易获得全切除。

Abstract：

Objective To review our experience of microsurgery for 60 cavernous sinus tumors from 2002 to 2009.The clinical features,surgical techniques and outcome of cavernous sinus tumor in 60 cases were investigated retrospectively.Methods The patients included 23 hemangiomas,18 shwannomas,9 dermoid cysts,4 meningiomas,3 chordomas,3 pituitary adenomas.AIl the tumors were removed with subtomperal preauricular extradural approach.Results The tumors were removed satisfactorily.The shwannomas were totally removed. The hemangiomas were totally removed in 18,near-totally removed in 5 cases.Nine dermoid cysts were removed totally.For the 4 meningiomas,3 were removed completely,neartotallv removed in 1 cases.The 3 Chordomas were resected near-totally and achieved a completely removal with combined approach.Conclusion The subtomperal preauricular extradural approach is a rational choice.It can reveal the cranial nerve branches and artery at an early stage so that cranial nerves Ⅲ～Ⅵ and internal carotid artery can be preserved during operation.The tumor exposure is ideal and brain traction and contusion are slightly.The adjunctive radiotherapy is demanded for residual tumors adhering to nerves and arteries severely.     

Parasellar syndromes

The parasellar compartments are located lateral to and on either side of the sella turcica. The cavernous sinuses are the most prominent anatomic feature of the parasella. Each sinus consists of a plexus of veins through which runs the intracavernous portion of the internal carotid artery. Ocular motor nerves three and four travel within the dural covering of the cavernous sinus to the superior orbital fissure, and cranial nerve six travels through the carotid sinus itself, giving rise to parasellar syndromes, which have distinctive clinical features. Ophthalmoplegia occurs as a result of damage to these ocular motor nerves and variable involvement of oculosympathetic nerves. Facial pain, dysesthesia, and paraesthesia are caused by damage to one or more of the divisions of the fifth cranial nerve, travelling in the dural wall of the cavernous sinus. Tumors, such as meningiomas, frequently cause parasellar syndromes, as do aneurysms of the intracavernous portion of the internal carotid artery, carotid-cavernous fistulas, and cavernous sinus thrombosis. Inflammatory conditions such as Tolosa-Hunt syndrome, ischemia to small vessels supplying the cavernous portion of the cranial nerves, and infections can cause this syndrome. Magnetic resonance imaging is the investigation of choice and therapy is specific to the cause of the parasellar syndrome, but now includes more aggressive endoscopic and microsurgical intervention, and radiosurgery.

The antero-medial triangle: the risk for cranial nerves ischemia at the cavernous sinus lateral wall. Anatomic cadaveric study

OBJECTIVE: Vascular damage in the cavernous sinus can cause ischemic injury to the cranial nerves. An appropriate anatomical knowledge of the blood supply to the cranial nerves can help to reduce the morbidity associated with cavernous sinus surgery. MATERIAL AND METHODS: Three formalin-fixed and six adult cadaveric fresh heads, with common carotid arteries injected, were used for anatomical dissection in this study. A fronto-temporal craniotomy was performed and the cavernous sinus was explored according to the Dolenc technique. With microsurgical dissection and photographic documentation, we demonstrate the anatomy of the superior orbital fissure artery in the antero-medial triangle. RESULTS: The 12 explored cavernous sinuses demonstrated the presence of two principal branches directly from the intracavernous internal carotid artery that supply the cranial nerves: the infero-lateral trunk and the meningohypophyseal trunk. The artery of the Superior Orbital Fissure (SOF), originated more often from the infero-lateral trunk, and vascularized the III, IV, VI, and VI, and ophtalmic division of the trigeminal nerve (TGN VI) at their entry in the fissure. CONCLUSION: In this study we demonstrate that the superior orbital fissure artery is a branch from the infero-lateral trunk which runs immediately under the reticularis layer at the level of the anteromedial triangle in the lateral wall of the cavernous sinus. The blood supply to all cranial nerves in the SOF is at risk to injury when the lateral wall of the cavernous sinus is transgressed at the anteromedial triangle since the SOF-artery runs superficially at this level.

Solitary juvenile xanthogranuloma mimicking intracranial tumor in children

Juvenile xanthogranuloma (JXG) is primarily a benign cutaneous disorder of non-Langerhans hystiocytic proliferation. Systemic involvement occurs in 4% of patients; isolated central nervous system (CNS) lesions are rare. We report solitary CNS-JXG lesions in two patients. A 3.5-year-old boy with a parietal-occipital lesion underwent total resection with no surgical morbidity and no recurrence at 16-month follow-up. A 3.5-year-old girl underwent subtotal resection of a tumor extending from the left Meckel’s cave and invading the cavernous sinus and left orbit with extensive cranial nerve involvement. Tumor regrowth with leptomeningeal spread at 9-month and 12-month follow-up was managed with steroids and chemotherapy (vinblastine and later cladribine). We present our experience and review the literature pertaining to rare reports of solitary CNS-JXG.

蝶骨嵴内侧脑膜瘤术后并发症相关因素分析

目的 探讨蝶骨嵴内侧脑膜瘤（mSWM）术后并发症的相关因素。方法 回顾性分析2011年1月至2021年1月经翼点入路或扩大翼点入路手术治疗的129例mSWM的临床资料。术后并发症定义为术后6个月仍存在神经功能障碍,如肢体偏瘫,外展神经麻痹,动眼神经麻痹,复视,视力下降,脑积水,意识障碍,癫痫发作,颅骨缺损等。结果 129例中,术后6个月存在并发症20例,并发症发生率为15.50%(20/129);一侧肢体偏瘫4例,术后因颅内血肿致意识障碍2例,动眼神经损伤3例,外展神经损伤3例,因术后脑梗死行去骨瓣减压术遗留颅骨缺损2例,术后发生癫痫大发作4例,视力下降2例。多因素logistic回归分析显示,肿瘤侵犯海绵窦（OR=4.205;95%CI 1.104～16.019;P=0.035）、肿瘤包绕颈内动脉或其分支（OR=3.501;95%CI 1.054～11.631;P=0.041）是m SWM术后发生并发症的独立危险因素。结论 对于侵犯海绵窦、包绕颈内动脉或其分支的m SWM,单纯追求肿瘤的全切除,会提高并发症的发生率,适当保留少量肿瘤,术后辅以放疗,可能是更好的选择。     

手术切除从颅底侵犯海绵窦的肿瘤

目的探讨手术切除侵犯海绵窦的颅底肿瘤的指征及手术要点。方法自1998年11月至2002年5月，中日友好医院神经外科与中国医学科学院肿瘤医院头颈外科合作，连续切除侵犯海绵窦的颅底肿瘤32例，其中鼻咽纤维血管瘤7例，脊索瘤5例，鼻咽癌和鼻咽囊腺癌5例，副鼻窦癌5例，神经鞘瘤3例，嗅神经母细胞瘤1例，颞下翼腭窝低分化癌2例，颞下翼腭窝肉瘤3例，恶性纤维组织细胞瘤1例。23例曾经1次或多次手术切除后复发。对临床资料进行回顾性总结。结果根据肿瘤主体的部位分别选用经上颌骨入路、颞下耳前入路、或额眶入路。全部病例术中显露满意，肿瘤均得到肉眼切除，受累的颅神经一并切除，无手术死亡，术后无偏瘫等严重并发症。、术后辅以放射治疗。随访3—50个月，平均19个月，失访3例，4例术后3—6个月死亡，4例带瘤生仔，21例健在。结论由下向上侵犯海绵窦的颅底肿瘤可以手术切除，近期效果满意。对颅底正常和病理性解剖结构的熟练掌握以及多学科医生的密切协作是手术取得成功的关键。     

Intraoperative electrical stimulation for identification of cranial nerve nuclei.

The purpose of this study was to evaluate the feasibility and usefulness of cranial nerve nuclei monitoring during resection of brainstem cavernous malformations. Eleven patients with brainstem cavernous malformations underwent resection of their malformations utilizing cranial nerve nuclei monitoring. Cranial nerves V and VII were monitored by placing electrodes in muscle groups innervated by these nerves and recording manipulation-induced neurotonic discharges and triggered electromyographic (EMG) activity, after electrical stimulation of the corresponding brainstem nuclei. Seven of 11 procedures (64%) with cranial nerve nuclei monitoring were noted to have cranial nerve nuclei activity corresponding to manipulation of the nuclei. The cavernous malformation was completely resected in 5 of 7 cases with cranial nerve nuclei activity and in all 4 cases without activity. In the remaining 2 cases, the cavernous malformation was not resected due to the proximity of the monitored cranial nerve nuclei to the cavernous malformation and to increasing neurotonic activity as the cavernous malformation was approached. None of the 11 patients had new permanent postoperative deficits corresponding to the cranial nerve nuclei monitored; 1 patient had a transient partial facial palsy lasting 2 days. Preliminary results indicate that cranial nerve nuclei monitoring proves useful in preserving neurologic function and reducing surgical morbidity during resection of brainstem cavernous malformations, particularly indicating when lesion resection places these nuclei at risk.     

Bilateral sphenoorbital hyperostotic meningiomas with proptosis and visual impairment: a therapeutic challenge. Report of three patients and review of the literature

Objective

Bilateral hyperostotic sphenoorbital meningiomas are extremely uncommon. Due to extensive infiltration of the orbits and the frontotemporal skull base, often only a subtotal tumor resection is feasible. Thus far, no treatment algorithms have been suggested for this rare tumor entity. We report on the surgical management of 3 patients.

Methods

All 3 patients underwent a pterional approach for surgical resection. Surgery was performed in two stages, primarily treating the most affected side. Treatment consisted of microsurgical resection of the infiltrated sphenoid wing and orbital walls, intraorbital tumor removal and optic nerve decompression. Orbital wall reconstruction was performed using titanium mesh allografts. Radiation therapy was administered in 1 patient with residual tumor infiltration of the cavernous sinus.

Results

Our series includes 2 women (51 and 68 years old) suffering from simultaneous progressive bilateral loss of vision and proptosis and 1 woman (69 years old) who developed contralateral disease after surgical resection of a hyperostotic sphenoorbital meningioma 16 years earlier. After optic nerve decompression, vision improved in 2 cases after surgery. Initial visual deterioration was observed in 1 case but improved on longterm follow-up. The degree of proptosis was reduced in all treated eyes.

Conclusion

In bilateral hyperostotic sphenoorbital meningiomas we propose staged surgery when clinical and radiological progression is observed. Subtotal tumor resection with the aim of optic nerve decompression and subsequent orbital reconstruction provides satisfactory results. The most affected eye should be treated first. In case of additional cavernous sinus infiltration, focal radiation therapy can be considered.     

经翼点入路显微手术切除内侧型蝶骨嵴脑膜瘤

目的探讨利用显微手术治疗内侧型蝶骨嵴脑膜瘤的方法。方法本文复习了16例内侧型蝶骨嵴脑膜瘤手术病人的临床资料，讨论了显微手术治疗内侧型蝶骨嵴脑膜瘤的原则、方法、手术技巧及手术要点。结果内侧型蝶骨嵴脑膜瘤全切除12例，大部切除4例，无手术死亡，疗效满意。结论在熟练掌握术区显微解剖的基础上，采用翼点入路，利用显微手术可明显提高肿瘤全切率，减少术后并发症，降低死亡率。但对与下丘脑，海绵窦等重要结构粘连过于紧密的肿瘤，即使采用显微手术，手术风险仍较大，可考虑姑息手术结合术后放疗。
