Abstract：

Objective To assess the feasibility,the risks and the advantages of endoscope-assisted submandibular gland resection using a retroauricular hairline incision ( RAHI) by comparing it with the conventional submandibular gland resection.Methods Twenty eight patients with benign lesions of the submandibular gland were included in the prospective clinically controlled study.Thirteen patients had endoscope-assisted resection using the RAHI approach and 15 cases had conventional transcervical approach resection.The size,location and adjacency of all lesions were evaluated by CT or MRI before surgery.The pathologic diagnoses of all cases were identified as benign diseases using fine needle aspiration biopsy.The two groups were compared for incision length,operation time,bleeding,incision cosmetic result,and complications.Results All 28 operations were successfully performed.Incision length in the endoscopic group was significantly longer than that in the trancervical group (Z =-4.516,P＜0.01),and the surgical time was longer in the endoscopic group( Z =-3.263 ,P ＜0.01) .After three months the mean subjective satisfaction score for the incision scar in the endoscopic group was significantly higher than that in the trancervical group(Z=-4.472,P＜0.01).In the endoscopic group,2 cases (15.4%) with temporary numbness of the earlobe and 1 case (7.7% ) with a temporary marginal mandibular nerve paralysis were found postoperatively.However,they recovered within 1 month.All 28 patients were disease free with a follow-up of 10 to 24 months (median of 18 months).Conclusions Endoscope-assisted submandibular gland resection via RAHI is feasible and safe for the treatment of benign submandibular gland lesions.In comparison with the transcervical approach,this method can provide better cosmetic results without significant complications.

Abstract：

Objective To explre the techniques, advantages and disadvantages, indications and cautions of a surgical approach for the resection of nasopharyngeal tumor. Methods Ten cases with nasopharyngeal tumors were recruited in this study, of them, 3 cases with residual nasopharyngeal carcinoma after chemoradiotherapy, 2 cases with cavernous angioma, 2 cases with benign mixed tumor, 1 malignant mixed tumor, 1 adenoid cystic carcinoma, and 1 chordoma. All patients underwent endoscopic resection of posteroinferior quarter part of nasal septum, and then the removal of nasopharyngeal tumors through bilateral transnasal approach. Results Total resection of the tumor was achieved for all cases without severe surgical complications. All cases with benign tumors, with following-up of 6 -18 months, showed no recurrence. Of 6 cases with malignant tumors, with following-up of 12 -48 months, 5 cases showed no recurrence, and 1 case was suspected to relapse one year postoperatively, but not with any lesion enlargement after another 6 month follow-up. Conclusions Posteroinferior quarter part of nasal septectomy is preferred for endoscopic resection of nasopharyngeal tumors because it can provide a panoramic view on nasopharyngeal cavity and tumors, thus, facilitating the removal of nasopharyngeal tumors.     

蝶窦良性侵袭性病变的临床诊治分析

目的　探讨蝶窦良性侵袭性病变的临床特点及内镜治疗。方法　回顾性分析19例蝶窦良性侵袭性病变的临床资料。19例均行内镜下经蝶入路病变切除。结果　内 翻性乳头状瘤6例,骨化纤维瘤7例,软骨瘤2例,嗜酸性肉芽肿4例。临床症状以头痛及视觉障碍多见。影像学共同特征是蝶窦骨壁破坏,周围结构受不同程度侵袭。术中发生脑脊液鼻漏1例,I期修复成功。术后全部患者无眶内及颅内并发症。随访3～5年,手术全切除15例无复发;次全或大部分切除4例,1例病灶无增大;3例复发,其中1例再次手术治愈,2例恶变并颅内转移死亡。结论　蝶窦良性侵袭性病变呈恶性肿瘤样行为,具有侵袭性、易复发性。内镜下彻底切除病变是防止复发的重要治疗方法。但有别于恶性肿瘤,应注意避免扩大切除范围。     

Endoscopic resection of benign and malignant tumors in the nasal cavity and paranasal sinus

Endoscopic resection of nasal and paranasal sinus tumors is more aesthetic and less invasive than conventional resection, such as Luc's operation and lateral rhinotomy. We clarified the effect of radical endoscopic tumor excision and the control of local bleeding hazardous in endoscopic surgery. Subjects were patients with benign lesions in the nasal cavity, medial wall of the maxillary sinus, ethmoid sinus, and/or sphenoid sinus without concurrent malignant lesions. Although patients selection for malignant tumor excision was based on (1) possible en bloc resection, (2) low-grade malignant tumors, and (3) tumors in the nasal cavity and adjoining paranasal sinus, the final decision was made individual. Subjects were 23 patients with benign tumor (10 inverted papilloma, 9 hemangioma, 2 juvenile angiofibroma, and 2 other tumors) and 4 with malignant tumor (olfactory neuroblastoma, acinic cell carcinoma, squamous cell carcinoma, and chondroid chordoma) in the nasal and paranasal sinus. The tumor was resected en bloc except for patients with inverted papilloma (2 cases) and chondroid chordoma. Recurrence in benign tumors was zero during a mean observation of 21 months. One with chondroid chordoma, however, suffered a recurrent lesion 7 months after the initial operation. The lesion was successfully salvaged by a similar endoscopic procedure and subsequently treated with electron beam irradiation. Preoperative arterial embolization, laser coagulation, and ligation of the sphenopalatine artery were very useful in reducing blood loss during surgery and maintaining a clear endoscopic view. In intraoperative bleeding volume, less than 100 ml of bleeding occurred during surgery in 23 of 27 patients. The endoscopic excision of benign lesions in the nasal and paranasal sinus is thus as effective as conventional radical surgery. Endoscopic removal of malignant lesions remains controversial because of the small number of patients and short postoperative observation.     

72例咽旁隙肿瘤的临床诊治

目的 分析并总结咽旁隙肿瘤的临床特点、手术方法及预后情况。方法 回顾性分析南京医科大学第一附属医院2012年11月—2022年11月收治的咽旁隙肿瘤患者的临床资料,排除影像学资料不全及失访的患者共筛选到72例,其中男36例,年龄27~72岁,平均年龄（46.06±1.72）岁;女36例,年龄21~77岁,平均年龄（53.67±4.88）岁。所有患者均根据术前查体及影像学检查制定手术方案,经口径路27例,颈侧径路45例。术后随访2～135.9个月,中位随访时间54.38个月。统计分析临床、影像及手术资料。结果 72例患者术后病理为良性肿瘤63例,其中上皮源性肿瘤29例,神经源性肿瘤30例,其他组织来源良性肿瘤4例;4例复发,其中2例神经鞘瘤,2例多形性腺瘤,余59例恢复良好;恶性肿瘤9例,其中鳞状细胞癌5例,恶性梭形细胞瘤1例,恶性淋巴瘤1例,滑膜肉瘤1例;3例复发。尽管良性咽旁隙肿瘤经口内镜手术存在囊内分块切除的情况,但相比整块切除的患者并未增加复发风险（P=0.381）。结论 咽旁隙肿瘤位置深在,临床结构复杂,良性肿瘤预后可,恶性肿瘤易复发转移,预后较差。根据术前查体和影像学检查制定手术径路至关重要。手术以颈侧开放径路为主要方式,内镜辅助径路需严格把握适应证,肿物长径较大时在包膜完整的情况下作囊内分块切除是可行的。     

原发性咽旁间隙肿瘤的诊断与治疗

目的 总结原发性咽旁间隙肿瘤的临床特征、诊断方法、手术方法及疗效.方法 回顾性分析解放军总医院2006年1月至2008年12月收治的40例原发性咽旁肿瘤患者的临床资料,其中男22例,女18例;年龄1 ～77岁,中位年龄42岁.CT扫描结合MRI检查有助于咽旁间隙肿瘤的诊断和手术方案的制定.手术方式包括:经口入路1例,经颈部入路22例,经腮腺-颈部入路8例,下颌升支纵行裂开入路1例,经颈部-下颌角部分切除入路4例,经腮腺进路2例,耳后颅颈联合入路2例.结果 40例患者均经手术切除,术后病理诊断良性肿瘤28例,恶性肿瘤12例,其中涎腺来源15例,神经来源12例,其余13例为其他组织来源.28例良性肿瘤中,23例经一次手术治愈,随访13～47个月无复发,中位数39个月.12例恶性肿瘤经随访3～50个月,中位数29个月,6例存活(随访时间24～ 50个月,中位数36个月),3例在术后6个月内死亡,3例失访.术后发生脑脊液漏1例,术腔感染2例,迷走神经损伤3例.结论 手术切除是治疗咽旁间隙肿瘤的首选方法,绝大多数肿瘤可以经单纯颈侧入路切除;对于恶性肿瘤或较大的良性肿瘤应选择较宽阔的手术入路.咽旁间隙的良性肿瘤预后较好,而恶性肿瘤组织类型复杂多样,治疗效果差,预后不良.     

经鼻内镜手术治疗鼻腔鼻窦骨源性良性肿瘤——附14例报告

目的探讨经鼻内镜手术治疗鼻腔鼻窦骨源性肿瘤的可行性及手术技巧。方法回顾性分析1998年6月-2012年5月经鼻内镜手术治疗的14例鼻腔鼻窦骨源性肿瘤的临床资料。所有患者均于术前行鼻窦高分辨CT（HRCT）检查,确定肿瘤的位置和侵犯范围。手术均在全身麻醉下进行,经鼻内镜手术11例,鼻内镜辅助鼻外径路手术3例。其中行肿瘤彻底切除9例,部分切除5例。结果所有患者术后平均随访5年7个月。2例侵及眶内及前颅窝的骨化纤维瘤患者分别于术后2个月和8个月复发,接受第2次手术后1例病变基本控制,目前仍在随访中,另1例去外院接受了第3次鼻颅脑联合手术再复发,仍在观察中;1例骨母细胞瘤患者采用经鼻经额联合径路内镜手术,但侵入前颅窝相当于鸡冠处的肿瘤仍有残留,术后2年患者因左侧眶内及颅内肿物复发去外院行开颅手术后失访;其余患者随访至今未见复发。所有病例均未发生其他严重并发症。结论鼻腔鼻窦骨源性肿瘤局限于鼻腔鼻窦者经鼻内镜手术可彻底切除;但当肿瘤破坏颅底突入颅腔或肿瘤侵及颈内动脉、视神经等重要结构时,单纯内镜下肿瘤不易彻底切除,需多学科的联合手术或其他辅助治疗。     

Long-term results of endonasal sinus surgery in sinonasal papillomas

OBJECTIVE: To assess the value of endonasal sinus surgery in the management of sinonasal papillomas. STUDY DESIGN: Retrospective study including 43 patients operated on for sinonasal papilloma in a long-term follow-up. METHODS: In 26 cases (60%) an endonasal approach, in eight cases (19%) an external approach, and in four cases (9%) a combined procedure was performed to remove these tumors. Five septal lesions (12%) were resected under direct vision. The original sections and charts of all patients were reviewed to assess clinical data. Follow-up information was available for 42 of our patients (98%) with a mean follow-up of 62 months. RESULTS: Histologic examination revealed 34 cases of inverted papilloma (79%), five cases of exophytic papilloma (12%), and four cases of columnar cell papilloma (9%). Malignancy occurred in 4 of 43 patients (9%), and recurrences developed in 8 of 42 patients (19%). Two of these recurrences happened after endoscopic sinus surgery (two inverted papillomas), three after lateral rhinotomy (three inverted papillomas), one after a combined procedure (one inverted papilloma), and two after simple resection (two exophytic papilloma). CONCLUSIONS: In keeping with our experience, the endonasal endoscopic approach, often in combination with a medial maxillectomy, is favored for the treatment of sinonasal papilloma because of a lower recurrence rate and a better cosmetic result. In some larger tumors and lesions in difficult locations, better visualization can be obtained by a combined external and endonasal approach.     

鼻内镜下泪前隐窝入路治疗上颌窦良性病变

目的经鼻内镜下泪前隐窝入路治疗上颌窦良性病变,并探讨其适应证、并发症及手术方式。方法回顾性分析43例经鼻内镜下泪前隐窝入路治疗上颌窦良性病变的病例,其中术前及术后病理确诊的上颌窦内翻性乳头状瘤15例,窦内病变镜下检出菌丝或孢子的真菌性上颌窦炎8例,上颌窦囊肿12例,上颌窦后鼻孔息肉6例,上颌窦异物2例。所有病例手术前均行鼻窦冠状位或水平位CT扫描。患者在局麻下以下鼻甲前缘为中心切口,解剖内移鼻泪管-下鼻甲瓣经泪前隐窝进入上颌窦腔处理上颌窦内病变,复位鼻泪管-下鼻甲瓣,缝合手术切口并行下鼻道开窗。结果 43例患者术中均完全清除窦内病变,术后随访6～24个月,下鼻甲形态愈合良好,术腔上皮化,无溢泪、面部麻木等并发症。2例上颌窦内翻性乳头状瘤术后6个月局部复发,原手术入路切除,随访1 8个月无复发。3例术后鼻腔粘连,局部分离,随访12个月无复发。结论经鼻内镜下泪前隐窝入路进入上颌窦是一种微创、安全、有效的处理上颌窦良性病变的手术方式,可作为鼻内镜下经中鼻道行上颌窦自然口开窗无法彻底切除窦内病变组织的首选治疗方法。     

经鼻内镜岩斜坡及颞下窝肿瘤的外科治疗

目的探讨经鼻内镜手术治疗岩斜区及颞下窝肿瘤的可行性和外科手术技术。方法2002年1月至2005年2月间对17例侵犯岩斜坡或颞下窝肿瘤单独采用内镜经鼻手术入路进行了治疗，详尽阐述外科手术技术及介绍典型病例。结果17例患者中脊索瘤5例，脑膜瘤4例，颅咽管瘤1例，神经鞘膜瘤1例，血管母细胞瘤1例，嗅神经母细胞瘤1例，恶性淋巴瘤1例，脊索肉瘤1例，腮腺癌颅底转移1例，甲状腺癌颅底转移1例。15例患者术后复查影像显示肿瘤全部被切除，2例大部分切除。所有病例随访5～43个月，良性肿瘤中有1例脊索瘤术后5个月复发，后行2次手术，其余均无复发。5例恶性肿瘤患者均随访2年以上，无复发或死亡。术后1例蛛网膜下腔出血、2例出现脑脊液鼻漏，其中1例经保守治疗痊愈、1例经2次鼻内镜手术修补成功。无颅内感染及死亡病例。结论经鼻内镜外科技术为岩斜区和颞下窝肿瘤的外科治疗提供了一种新的方法。这种入路能够简单和迅速地到达岩斜区和颞下窝，且既能够达到微侵袭目的，又能够满足全切肿瘤的要求。但需要术者熟练掌握内镜颅底解剖学、内镜手术操作及对各区域病变丰富的外科手术经验。术中应用影像导航系统将有助于识别解剖标志，使手术过程更加安全。

Transnasal endoscopic resection of juvenile nasopharyngeal angiofibroma without preoperative embolization

Juvenile nasopharyngeal angiofibroma (JNA) is a benign, highly vascular, and locally invasive tumor. Because the location of these tumors makes conventional surgery difficult, interest in endoscopic resection is increasing, particularly for the treatment of lesions that do not extend laterally into the infratemporal fossa. We report the results of our series of 23 patients with JNA (stage IIB or lower) who underwent transnasal endoscopic resection under hypotensive general anesthesia without preoperative embolization of the tumor All tumors were successfully excised. The amount of intraoperative blood loss was acceptable. We observed only 1 recurrence, which was diagnosed 19 months postoperatively in a patient with a stage IIB primary tumor. We observed only 3 complications during follow-up-all synechia. We conclude that endoscopic resection of JNAs is safe and effective. The low incidence of recurrence and complications in this series indicates that preoperative embolization may not be necessary for lesions that have not undergone extensive spread; instead, intraoperative bleeding can be adequately controlled with good hypotensive general anesthesia.     

鼻腔鼻窦骨良性病变累及眼眶的鼻内镜手术

目的探讨累及眼眶的鼻腔鼻窦骨良性病变鼻内镜下手术处理方法,分析手术运用特点、手术并发症及疗效。方法回顾性分析南京大学医学院附属鼓楼医院耳鼻咽喉科2014年1月—2018年7月收治的13例累及眼眶的骨良性病变,其中骨瘤7例,骨纤维异常增殖症4例,骨化纤维瘤2例。2例筛窦骨瘤突入眶内,其余11例均有眶壁不同程度受累。所有患者均经鼻内镜手术,部分患者结合运用影像导航技术、鼻中隔开窗及泪前隐窝入路手术,术中准确定位病变界限,对突入眶内病变及受累的眶组织予以彻底切除。所有手术操作均以保护并不突破眶筋膜为原则,除1例突入眶内巨大筛骨骨瘤外,其余术毕均未予眶壁重建处理。结果所有患者均经鼻内镜完成手术,受累眶壁及眶内骨性病变均切除彻底。5例患者术后第1天出现眶周轻度肿胀,取出鼻腔填充物后消除,无眼球功能障碍。术后复查CT显示眶内解剖结构及位置正常。随访11～65个月,所有患者均无复发。相关鼻窦引流通畅、上皮化良好,无远期并发症。结论彻底切除骨良性病变的眶受累解剖结构有利于减少术后复发,鼻眼相关解剖及手术视野和操作角度是手术成功的要点,经鼻内镜手术处理累及眼眶的骨性病变具有微创和疗效好等优势。     

Endoscopic management of the inverted papilloma with attachment to the frontal sinus drainage pathway

CONCLUSION: Extensive inverted papilloma (Krouse T3 lesions) with attachment to the frontal sinus drainage pathway can be treated successfully using an endoscopic approach. OBJECTIVES: The endoscopic management of inverted papilloma (IP) has gained in popularity over the last 15 years. However, the appropriate management of lesions involving the frontal sinus and its drainage pathway still has to be determined. PATIENTS AND METHODS: We performed a retrospective review of the results for patients with IP in the Otolaryngology, Head and Neck Surgery Department, Beijing Tongren Hospital from 2004 to 2007 to identify those patients with lesions involving the frontal sinus and its drainage pathway. By their appearance on nasal endoscopic examination and by computed tomography scanning, the tumors were defined using the Krouse staging system. Sinus endoscopy was used to screen for disease after endoscopic resection and the clinical outcomes were analyzed. RESULTS: A total of nine patients (eight males and one female) were identified in which IP involved the frontal sinus and its drainage pathway. Preoperative and postoperative pathological examinations revealed IP as the diagnosis. All tumors were defined as T3 lesions. Four cases with lateral wall of frontal recess tumor attachment underwent an endoscopic Draf IIA frontal sinusotomy. Three cases with either lateral and posterior walls of frontal recess and frontal infundibulum attachment, or medial and posterior walls of frontal recess and frontal infundibulum attachment underwent a Draf IIB procedure. Two cases with posterior wall of frontal recess and frontal infundibulum attachment, or medial, lateral, and posterior walls of frontal recess and frontal infundibulum attachment underwent a Draf III procedure. All patients remain disease-free after an average follow-up period of 15 months.     

Endoscopic sinus surgery for the treatment of vascular tumors

BACKGROUND: This study points out the effectiveness of the endoscopic approach for the treatment of vascular lesions such as angiofibroma, hemangioma, and hemangiopericytoma involving the nose and paranasal sinuses. METHODS: We performed a retrospective study at an academic tertiary referral center. Thirteen patients, diagnosed with vascular tumors of the nose and paranasal sinuses were treated endoscopically between February 1996 and July 2003. All patients underwent endonasal endoscopic surgery. Preoperative angiography with embolization was performed in all but two cases. RESULTS: The follow-up of this series varied from 6 to 75 months (mean, 23 months); only one recurrence (8%) was observed in the juvenile angiofibroma group encountered 20 months postoperatively. This recurrence was again treated endoscopically. The average intraoperative blood loss for the removal of the juvenile angiofibroma group was 300 mL and it was 100 mL for the other vascular tumors. CONCLUSION: Endoscopic treatment alone is an effective approach for the removal of selected cases of vascular tumors. Even in the presence of a lesion with limited intracranial extension, the tumor still may be amenable to an endoscopic approach alone. On the contrary, this is not true if the intracranial extension receives feeding vessels from the internal carotid arterial system.     

侵犯颅底的头颈部肿瘤的手术治疗

目的：探讨侵犯颅底的头颈部肿瘤的手术治疗方法。方法：对32例侵犯前、侧颅底的头颈部肿瘤患者进行手术治疗,采用鼻内镜下鼻腔入路5例,颅-面联合入路3例,上颌骨切除入路15例,口腔硬腭入路1例,经下颌入路1例,颈侧-下颌骨切开入路2例,耳后-颈联合入路1例,额颞入路2例,经面入路2例。结果：4例鼻窦黏液囊肿仅作开放引流,1例脊索瘤作次全切除,其余27例患者均全切肿瘤,无手术死亡及严重颅脑并发症。8例良性肿瘤患者随访6个月~8年情况良好,无肿瘤复发及死亡。24例恶性肿瘤患者,术后随访3年以上19例,生存12例;随访5年以上12例,生存5例;术后3、5年生存率分别为63.2%（12/19）和41.7%（5/12）。结论：根据病变性质、部位及范围设计手术入路,力求全切肿瘤并保护重要结构,采用适当的颅底修复方法,可获得良好的治疗效果。     

原发性咽旁间隙肿瘤67例回顾性分析

目的 分析原发性咽旁间隙肿瘤的临床特点及手术径路选择,探讨不同手术径路的优缺点及预后。方法 回顾性分析67例咽旁间隙肿瘤患者资料,所有患者术前均行CT和(或)MRI检查,三种手术路径分别为颈侧径路45例、口内径路20例、颈-腮径路2例。术后病理学检查明确诊断,对所有手术患者进行术后定期随访,随访时间8～110个月,中位随访时间45个月。结果 67例中良性肿瘤共59例(88.1%),恶性肿瘤8例(11.9%);24例(35.8%)患者出现术后并发症,其中颈侧径路20例(29.9%),口内径路3例(4.5%),颈-腮径路1例(1.5%),其中7例(10.4%)随访后好转。复发患者7例(10.4%),颈侧径路4例(6.0%),口内径路3例(4.5%)。结论 咽旁间隙解剖毗邻复杂,病理类型繁多,肿瘤以良性为主,治疗以手术切除为主。术前根据影像学检查结果,肿瘤大小及解剖关系决定手术径路。颈侧径路仍是咽旁间隙肿瘤切除的首选方法,但在肿瘤最大直径<6 cm并位于动脉内侧的良性肿瘤患者中,可考虑口内径路。     

鼻内镜下切除累及额窦及其引流通道的内翻性乳头状瘤

目的鼻腔鼻窦内翻性乳头状瘤是头颈部常见的良性肿瘤之一，但累及额窦及其引流通道的内翻性乳头状瘤既往报告不多。本研究采用经鼻内镜手术治疗累及额窦及其引流通道的内翻性乳头状瘤，探讨相应术式的适应证及疗效。方法累及额窦及其引流通道的乳头状瘤患者9例（男8例，女1例），年龄23～70岁，中位年龄52岁。所有患者术前均接受CT检查，5例行MRI检查，组织病理学诊断均为内翻性乳头状瘤。根据病变范围进行分期，然后进行经鼻内镜手术治疗并观察疗效。结果根据Krouse分期系统，所有患者病变均为13期，经鼻内镜手术顺利切除肿瘤，其中肿瘤的根基部位于额隐窝外侧壁者4例，采用DrafⅡA型手术；肿瘤根基部位于额隐窝和额漏斗内侧壁和后壁，以及外侧壁和后壁者3例，采用DrafⅡB型手术；he瘤根基部位于额隐窝和额漏斗后壁，或者内侧壁和后壁，且肿瘤累及双侧额窦者2例，采用DrafⅢ型手术。所有患者均在鼻内镜下随访，其中3例术后复查CT，随访5～34个月，中位随访时间16个月。术后组织病理学检查结果均符合术前诊断，未发现局部恶变。结论术前CT和病理检查对明确病变部位和性质至关重要，MRI检查可起到良好的辅助作用。经鼻内镜手术去除累及额窦及其引流通道的T3期乳头状瘤，可取得良好的近期疗效。     

Endoscopic resection of sinonasal hemangiomas and hemangiopericytomas

INTRODUCTION: Endoscopic resection of benign neoplasms, such as inverted papilloma, has been well described. There are limited case reports of endoscopic resection of benign vascular tumors, including hemangiomas, or those with low-grade malignant potential, such as hemangiopericytomas. METHODS: Retrospective review of sinonasal hemangiomas and hemangiopericytomas resected endoscopically at a single tertiary-care facility. RESULTS: Three hemangiomas and 3 hemangiopericytomas were resected endoscopically with no recurrences at a mean follow-up of 22 months. Four tumors involved the skull base; 2 of these underwent preoperative embolization. One patient had a CSF leak that occurred as the tumor was removed from the cribriform plate and that was successfully repaired intraoperatively. The average size of the tumors was 5.8 cm x 2.7 cm with all tumors at least 2.5 cm in greatest dimension by computed tomography or magnetic resonance imaging. The largest tumor was 12 cm in greatest dimension. An average of 8 intraoperative frozen section margins was taken around 5 tumors, with all margins of each tumor clear on final pathology. Patients included 4 males and 2 females with an average age of 47 years. CONCLUSION: Large vascular neoplasms of the sinonasal cavity, such as hemangiomas and hemangiopericytomas, can be safely removed using endoscopic techniques. Although these patients have a limited follow-up, it is prudent to perform long-term endoscopic follow-up in order to detect recurrences regardless of resection technique.     

Endoscopic endonasal approach for the treatment of anterior skull base tumours

INTRODUCTION: The increasing expertise of transnasal endoscopic surgery has recently expanded its indications to include the management of tumours affecting the skull base. We report our experience with endoscopic management of these tumours, emphasising the indications and surgical technique used. MATERIAL AND METHOD: A retrospective analysis was performed of patients treated by an endoscopic endonasal approach (EEA) in our department from 2004 until 2011. RESULTS: Sixty-three patients were analysed. We performed an endoscopic craniofacial resection in 32 patients (51%), an expanded EEA in 22 (35%), a transclival approach in 6 (9%) and a transpterygoid approach in 3 (5%). The most frequent benign tumour was nasopharyngeal angiofibroma (24%), while adenocarcinoma (30%) was the most common among malignancies. Mean follow-up was 26 months (range: 6 to 84 months). The complication rate was 5% and resection was complete in 56 cases (89%). The 5-year overall-survival was 71% in patients with malignant tumours and the effectiveness was 100% in benign tumours. CONCLUSION: Our results support that endoscopic surgery, when properly planned, represents a valid alternative to standard surgical approaches for the management of skull base tumours.
