鼻内镜下微型柯-陆手术治疗上颌窦病变

传统治疗上颌窦病变是经唇龈沟内切口行上颌窦根治术,该术式对患者的损伤较大,出血多,而且对上颌窦自然开口附近的病变不能彻底的清除。随     

上颌窦根治术（柯—陆术）和鼻内镜手术（EES）术后远期效果

柯-陆术式已广泛应用逾100年,批评很多,而EES注重保留功能,仅去除粘膜最严重病变和漏斗区的阻塞因素。二种术式的选用近年文献上有较多争论,认为息肉型或息肉-化脓型慢性上颌窦筛窦炎的窦粘膜病变不可逆转(即使通气、引流条件等已改善),故一些学者赞成仍应去除全部病变粘膜,动物实验证实柯-陆术后2周已开始有下鼻道纤毛上皮经对孔向术腔内长入,术后6～9个月时可完全被覆正常的柱状纤毛上     

鼻内窥镜加柯-陆手术联合进路治疗慢性鼻窦炎

目的：探讨提高慢性鼻窦炎疗效的方法。方法：对１０４例伴有上颌窦病变的慢性鼻窦炎患者行鼻内窥镜和柯－陆手术联合进路鼻窦手术,彻底清除病变。结果：术后随访６～１２个月（平均９个月）,治愈８５例（８１．７％）,好转１５例（１４．４％）,无效４例（３．８％）,总有效率９６．１％。结论：该方法可彻底清除上颌窦病变,恢复上颌窦的生理性引流通道,防止复发,弥补了经鼻内窥镜鼻窦手术在处理上颌窦病变时的局限性。     

功能性上颌窦手术与上颌窦根治术的疗效比较

对显微镜下行功能性上颌窦手术，即上颌窦自然口扩大术，及传统上颌窦根治术共８９例外 颌窦疾病患者，进行术后随访。其中，行自然口扩大术３９例，传统上颌窦根治术５０匀作鼻及鼻窦内窥镜检查。结果显示，Ａ组的治愈率及造口通虫经，均较Ｂ组为高，但窦腔或窦口息肉以Ａ组发生率为高。表明前者疗效较后者更具优势，但亦有其不足。     

医源性上颌窦异物1例

上颌窦冲洗管的改进

上颌窦炎是鼻科临床上的常见病和多发病之一，进行上颌窦穿刺冲洗是治疗上颌窦炎的一种有效治疗措施，因而是极为常用的一种操作技术，其中上颌窦冲洗管是直接影响操作能否顺利进行的不可缺少的一种重要器具。 传统的上颌窦冲洗管多采取临时制作的方法：用一段普通橡胶管，一端连接普通金属粗注射针头（使用时连接注射器），另一端连接玻璃管接头（使用时连接上颌窦穿刺针），橡胶管与粗针头及玻璃管接头之间用丝线束缚（见照片１）。在多年的实际操作过程中，我们体会到这种传统的上颌窦冲洗管有许多不便之处：由于普通橡胶管不耐高温，在…     

上颌窦囊肿手术进路的选择

目的探讨鼻内镜下3种摘除上颔窦囊肿进路的选择。方法本组上颌窦囊肿共32例,术前均经鼻窦CT扫描和鼻内镜检查,明确鼻腔情况、囊肿的大小及位置。其中8例伴鼻窦炎鼻息肉者,经中鼻道自然口开放术进路行Messerkling术;19例单纯上颌窦囊肿患者,鼻内镜下经改良柯-陆进路行囊肿摘除术,另5例采用下鼻道开窗进路行囊肿摘除术。结果术后随访6个月～1年,鼻窦CT冠状位扫描或鼻内镜检查,19例经改良柯-陆进路者术后无复发;8例经中鼻道自然口开放术进路者,2例复发,1例术后窦口闭锁,中鼻甲与鼻腔外侧壁粘连;5例经下鼻道开窗进路者,1例复发,2例失访。结论3种术式各有优缺点,临床中应根据不同情况酌情选用。

Cholesterol granuloma in the maxillary sinus

A 35-year-old male complained of recurring headache and nasal obstruction over a 4-year period. A Caldwell-Luc operation was subsequently performed on the left maxillary sinus and a greenish appearing material was removed. Microscopic examination of the tissue specimen showed a granulomatous tissue with typical cholesterol clefts and inflammatory changes consistent with chronic sinusitis.

双侧扩大蝶窦成形术在蝶窦病变中的应用

目的探讨双侧扩大蝶窦成形术在蝶窦病变中的应用价值。方法2012年12月～2017年6月,解放军南京总医院耳鼻咽喉头颈外科采用双侧扩大蝶窦成形术治疗蝶窦病变患者42例,随访6～53个月,观察其手术疗效及并发症。 结果15例难治性蝶窦炎患者术后蝶窦口开放良好,术腔清洁,均治愈;其余患者均彻底切除病灶,其中1例真菌性蝶窦炎伴颅内感染并发热患者术后予抗真菌治疗3个月后颅内病灶吸收,2例蝶窦癌、1例蝶窦脊索瘤患者及1例嗅神经母细胞瘤侵犯蝶窦及颅内患者术后均行放疗。42例患者术后除2例嗅觉减退及1例视力下降无明显好转外,余症状均明显缓解,未发生动脉性鼻出血、嗅觉减退及鼻中隔穿孔等并发症,术后患者术腔黏膜均上皮化良好,黏膜完全上皮化时间平均8.6周。2例蝶窦癌患者分别随访10、14个月,蝶窦脊索瘤患者随访10个月,均未复发;1例嗅神经母细胞瘤侵犯蝶窦及颅内患者随访8个月未复发。所有患者随访至今,均未发现蝶窦口再闭。结论采用双侧扩大蝶窦成形术治疗蝶窦病变,术野暴露清晰,蝶窦开放充分,术腔上皮化时间短,手术安全性高,术后随诊处置直观,是一种值得推广的手术方法。     

鼻内镜手术开放上颌窦口大小与术后疗效的探讨

目的探讨鼻内镜手术中扩大上颌窦口大小与术后疗效的关系。方法采用自身配对,研究120例双侧病变相近的、术中见双侧上颌窦窦口均有病变的I、II型慢性鼻窦炎鼻息肉患者,对比一侧窦口尽量扩大,另一侧常规扩大,术后不同时期鼻腔症状改善情况及窦口开放率。结果术中尽量扩大窦口一侧在不同时期其症状改善程度均优于常规扩大侧,随访6个月,窦口开放良好率为96.7%。结论鼻内镜手术中,对上颌窦窦口有病变者,尽量扩大窦口,有利于上颌窦通气引流,提高手术疗效。     

Schwannoma of maxillary sinus

Schwannoma, also known as neurilemmoma, is a solitary, encapsulated peripheral tumour of neuroectodermal derivation that originates from schwann cells of neural sheath of motor/ sensory peripheral nerves or sympathetic nerves. About one- third of all schwannomas occur in head and neck region but nose and paranasal sinuses, are rare sites. We report a case of schwannoma arising from the maxillary sinus and eroding the orbital floor. To the best of our knowledge, this is the sixth; case of schwannoma solely arising in the maxillary sinus, reported in the literature.     

A comparative study of the ciliary area of the maxillary sinus mucosa and computed tomographic images

The ciliary area of the maxillary sinus mucosa and coronal sinus computed tomographic (CT) scans were studied in 36 maxillary sinuses of 28 patients with chronic sinusitis. Tissue specimens allowed ciliary surfaces to be observed under scanning electron microscopy, allowing surfaces to be expressed in terms of ciliary area (CA) as the percentage of mucosal surface occupied by cilia. The opacity produced by mucosal swelling and secretion in the maxillary sinus on CT was assessed by two methods: Min’s and modified van der Veken’s methods. Both techniques indicated an inverse correlation between opacity of the maxillary sinus and CA. Our findings suggest that the opacity of maxillary sinus on CT could be a significant parameter for predicting the surface conditions of ciliated maxillary mucosa prior to sinus surgery.

Mucociliary function of the maxillary sinuses after restoring ventilation: a radioisotopic study of the maxillary sinus

Ostium patency and sinus ventilation play a key role in the normal function of the sinuses and the pathogenesis of sinusitis. Experience with endoscopic treatment modalities has indicated that even severe mucosal disease in the maxillary and frontal sinuses will heal after eradication of an infectious focus in the ethmoid and maintaining ventilation and drainage of sinuses. The aim of this study was to use scintigraphic methods to evaluate possible differences in mucociliary function of chronically diseased maxillary sinuses after establishment of ventilation. Fourteen patients (22 maxillary sinuses) and 3 controls (6 maxillary sinuses) were evaluated after functional endoscopic sinus surgery. The drainage ratios of sinuses at 20 min were calculated at the 3rd postoperative day and again at 3 weeks. When the early and late postoperative drainage ratios were compared it was found that mucociliary function returned to normal after 3 weeks in sinuses with cysts but without hyperplastic mucosal degeneration. While the mucociliary function and drainage improved significantly in sinuses with hyperplastic mucosa, depending on the severity and extension of the pathology present, it was still less than levels found in normal sinuses at 3 weeks.
