ObjectiveTo investigate the changes of basal membrane thickness in ethmoid mucosa in chronic rhinosinusitis.

目的：观察慢性鼻-鼻窦炎筛窦黏膜中基底膜的厚度变化。

Ethmoid sinusitis is frequently complicated in children by orbital cellulitis and abscess.

Results According to the relation of posterior ethmoid sinus to sphenoid sinus.

结果 根据后组筛窦蝶窦的位置关系分为蝶前型(49.2％)，蝶侧型(36.7％)和蝶上型(14.2％)。

Results Among the 15 cases, the lesions occurred in ethmoid sinus in 6 cases, in frontal sinus in 4 cases, in sphenoid sinus in 3 cases, in frontal hone in 1 case and in frontal process of maxila in 1 case.

结果 15例中病变起源于筛窦6例，额窦4例，蝶窦3例，额骨、上颌骨额突各1例；10例首发病例多呈卵圆形，形态规则，5例复发病例中4例形态不规整。

And patients, most patients with type Ⅰ belongs to the patient,Ⅱ sinusitis ethmoid sinus sclerosis type person is not high, and the proportion passed perioperative treatment, inflammatory condition to get a good control of the disease, making it easier to identify and excision, hemorrhage, this is also significantly reduce local anesthesia for surgery provided the foundation.

就患者而言，目前大多数的患者是属于Ⅰ与Ⅱ型的鼻窦炎患者，筛窦硬化型者占比例不高，而且经过正规的围手术期治疗，炎症状态得到了良好控制，使术中病变的辨认与切除较为容易，出血也明显减少，这也为手术局部麻醉提供了基础。

Kennedy et al [4] reported changes in the ethmoid bone in pathology specimens taken from individuals with CRS. These changes were similar to those seen in osteomyelitis and could play a role in failure of oral antibiotic therapy.

Kennedy等[4]发现，慢性CRS的筛窦有类似于骨髓炎一样的改变，这可能是口服抗生素用于治疗慢性CRS经常失败的原因。

Results Paranasal sinus malignant tumor root mainly in maxillary sinus 17 cases (54.8%), then ethmoid sinus 10 cases (32.3%), and frontal sinus 4 cases (12.9%).

结果：鼻窦恶性肿瘤多原发于上颌窦17例（54.8%），其次是筛窦10例（32.3%）和额窦4例（12.9%）。

The ethmoid part because of the osteoma, is due to orbital osteoma oppression near the nerve, before the swelling and pain caused orbit.

而因筛窦部位的骨瘤，则是因骨瘤压迫到眼眶附近的神经，才引起眼眶的肿痛。

The most two common used approach of saddle area operation (extemal ethmoid approach and transnasal sphenoid approach) was observed.

观测鞍区手术最常用的二种进路经鼻外筛窦蝶窦时路及经鼻中隔蝶窦进路的相关影像解剖。
