Effect of irrigation of the nose with isotonic salt solution on adult patients with chronic paranasal sinus disease

In a prospective, randomized, controlled, double-blind trial we compared the effectiveness of endonasal irrigations with Ems salt solution to that with sodium chloride solution in the treatment of adult patients with chronic paranasal sinus disease. Subjects (n = 40) were randomly allocated to treatment either with isotonic Ems salt solution or with isotonic sodium chloride solution. The treatment consisted of endonasal irrigation twice daily and additional nasal spray as required. Nasal endoscopy, plain radiography of the paranasal sinuses, olfactometry, anterior rhinomanometry, and a saccharin-clearance test were carried out on days 1 and 7. Patients recorded rating scales of general discomfort, nasal airway obstruction, agreeableness of the irrigation, duration of improved nasal resistance after each irrigation, and the amount of additional nasal spray in a diary. Nasal air flow was not improved significantly. Subjective complaints, endonasal endoscopy, and radiography results revealed a significant improvement in both groups (P = 0.0001). In comparison, the two groups were not significantly different in outcome. Endonasal irrigations with salt solutions are effective in the treatment of chronic sinusitis, and a significant difference between Ems salt and sodium chloride was not observed.

针刺对变应性鼻炎患者血浆内皮素及鼻粘膜微血管的影响

目的对３３例常年性变应性鼻炎患者进行针刺治疗,以观察其对血浆内皮素（ｅｎｄｏｔｈｅｌｉｎ,ＥＴ）及鼻粘膜微血管的影响。方法①血浆ＥＴ测定：采用特异性放射免疫法（均相竞争法）直接测定血浆ＥＴ含量。②鼻粘膜微血管的观察：主要观察鼻粘膜微血管管径、管袢数及鼻粘膜微血管的形态。③针刺治疗：选择曲池、血海两穴进行针刺。结果变应性鼻炎患者鼻粘膜微血管管径针刺后较针刺前增粗;针刺后变应性鼻炎患者鼻粘膜微血管形态变化以灯丝状微血管增多、网络状微血管减少为特征;变应性鼻炎患者鼻粘膜微血管管袢数针刺后较针刺前增多;变应性鼻炎患者针刺后血浆ＥＴ含量明显降低。结论变应性鼻炎针刺后鼻粘膜微循环明显改善,表现为鼻粘膜微血管管径增粗,灯丝状微血管增多、网络状微血管减少,管拌数增加,并与血浆ＥＴ存在密切关系,其机理可能是通过降低血浆ＥＴ的水平而起作用的。     

小儿鼻颅底针形内窥镜的检查与手术

目的：探讨应用针形内窥镜对小儿鼻颅底疾病进行探查与手术的方法及疗效。方法：在外径１．９ｍｍ的进口针形内窥镜及电视同图像系统监视下,对８例小儿（７ｄ￣１２岁）鼻颅底有关疾病进行探杳与手术。结果：先天性后鼻孔闭锁３例中,１例好转,３例痊愈。外伤性脑脊液鼻漏１例,经修补痊愈先天性脑膜脑膨出２例,确诊后１例暂缓治疗。另１例行内窥镜手术痊愈。颅底神经母细胞瘤２例取材作病理检查确诊。结论：在电视图像监视下应用     

蝶窦囊肿诊治47例分析

目的：提高对蝶窦囊肿的认识,以利于其诊断和治疗,方法：回顾性分析蝶窦囊肿４７例,总结其发病趋势、临床表现,影像学特征及治疗效果。结果：蝶窦囊肿最主要的临床症状为头痛,约占６４％;其次为眼部症状,再次为鼻部症状。蝶窦囊肿最易易及视神经,影响者视力,早期手术有利于神经力的恢复。鼻内窥镜下蝶窦囊肿摘除了术有损伤小,出血少,痛苦轻,手术时间短、安全,术后恢复快等优点。结论：ＣＴ、ＭＲＩ和鼻内窥镜的应用,提     

Schwannoma of the nasal septum: a case report with review of the literature

Schwannomas are neurogenic neoplasms rarely found in the sinonasal tract, where localization to the nasal septum is exceedingly rare (only 11 cases have been described in the western literature). We report the case of a 29-year-old white male with a schwannoma completely filling the left nasal fossa and arising from the bony part of the septum. A computer tomography (CT) scan and a biopsy suggestive of benign schwannoma were obtained before the lesion was removed by a degloving approach. The preoperative diagnosis of nasal septum schwannoma was confirmed. The patient is asymptomatic and without endoscopic evidence of recurrence 7 years after surgery. A review of the literature with particular emphasis on the clinical presentation, histological features, differential diagnosis and therapeutic options for such a rare lesion is included.

The rheological characteristics of nasal mucus in patients with rhinitis

In this paper we have analyzed the physical properties of nasal mucus from 120 outpatients with rhinitis. We focused on the most relevant rheological features: viscosity, elasticity, adhesiveness, as well as ability to be spun (spinability) or poured (pourability). A double-capillary type viscometer was used to measure viscosity and elasticity and the platinum ring method to measure adhesiveness. Spinability was measured with an automatic apparatus (Filancemetre Sefam) and pourability was determined by describing flow under gravity. Efficacy of nasal clearance was analyzed by measuring mucociliary transport time with an inert tracer using vegetal charcoal powder. Results showed that impaired nasal mucosal function in patients with rhinitis could be determined by studying rheological features in addition to measuring mucociliary activity. Information provided proved invaluable when considering possible treatment with agents affecting kinesis of nasal mucus.
