耳炎培养基和外耳炎外部的差异

中耳炎vs Externa中耳炎|耳炎外部与媒体临床表现，调查，管理和预后

Otalgiais common in both children and adults. It either could be resulted from local causes or may be referred. Depending on which part of the ear is involved, local causes can further be categorized as otitis media, where the middle ear cavity is involved, and otitis externa, where the external ear is involved. This article points out the differences between otitis media and externa with regard to its anatomy, etiology, pathology, clinical presentation, investigation findings, management and prognosis.

中耳炎

这是中耳的炎症。中耳意味着中耳裂缝是尤斯塔克式的管，中耳，atic，aditus，antrum和乳突空气电池。

根据时间关系，它进一步被归类为急性和慢性。通常，急性中耳炎介绍了病毒感染或上呼吸道感染，但成术生物很快就会侵入中耳。它通常在起源和自我限制状态下病毒。

通常，早期的中耳炎患者会出现耳聋和耳痛，会干扰睡眠，并且在自然界中th动。患者可能会发烧高度，并且不安。在化脓的阶段，耳痛会变得令人难以置信，并且在鼓膜膜的破裂后发生症状。除非解决，否则可能会导致急性乳突炎，骨膜下脓肿，面部瘫痪，迷宫炎，岩化性，硬脑膜脓肿，脑膜炎，脑脓肿或外侧窦性血栓性血栓性症。慢性中耳炎是由胆囊瘤形成引起的，可以是先天性或起源的。慢性中耳炎的并发症几乎与急性中耳炎，例如疼痛，颅内并发症，面部无力，脑膜炎等。半圆形管的侵蚀会导致眩晕。

急性中耳炎是诊断如果鼓膜的我mbrane appears inflamed, red and bulge with loss of landmarks on otoscopic examination. A yellowish spot may be seen on the tympanic membrane where the rupture is imminent. In chronic otitis media, perforation of the tympanic membrane may be seen either centrally or peripherally. Apart from X-ray mastoid, CT scan of the temporal bone, culture and sensitivity of ear discharge, and audiogram to assess hearing are used to diagnose and assess complications.

中耳炎的治疗包括抗菌治疗，充气剂，镇痛药，耳厕，干燥的局部热量，杂造术以及诸如伴随感染扁桃体，腺样体，鼻过敏，外科手术治疗，外科治疗方案和造型性手术等促成原因的治疗。

在急性中耳炎中，预后很好，除非复杂。然而，患有急性中耳炎的复发性发作儿童，具有积液和慢性中耳炎培养基的中耳炎患有导电性和感觉性听力损失的高风险。

耳炎外部

It is the inflammation of the outer ear and the ear canal. It is further subdivided on etiological basis into infective group and reactive group. Infective group includes bacterial, fungal and viral infections while reactive group includes eczematous otitis externa, seborrhoeic otitis externa and neurodermatitis.

通常，一名外耳炎患者主要出现耳痛，当外耳轻轻触摸或拉动时会恶化。拉动tragus引起的疼痛是身体检查中急性中耳炎的诊断。患者还可能注意到耳朵出院和发痒。收集碎屑和伴有肉类肿胀的排放可能会导致暂时的导电听力损失。

在耳镜检查中，可能是显而易见的。尼日尔可能以黑头丝状生长和念珠菌感染为白色或奶油矿床。

Management of acute otitis externa is mainly symptomatic. It includes antibacterial therapy, analgesics, applying local heat, ear toilet and medicated wicks.

如果外耳炎对治疗的反应良好，则预后是好的，但是如果忽视，可能会发生并发症。通常，老年糖尿病患者和免疫抑制药物的糖尿病患者更容易发生并发症，例如Externa恶性/坏死性中耳炎。

外耳炎和外耳炎外耳炎有什么区别？ • Otitis media is inflammation of the middle ear while otitis externa is inflammation of the outer ear and ear canal. • Otitis media usually results from infections, while common causes of otitis externa are reactive lesions such as eczematous ear canal skin, and putting objects to the ear canal. •拉动tragus引起的疼痛是身体检查中急性中耳炎的诊断。 •中耳炎如果复杂，可能会导致导电性和感觉性听力损失，但外耳炎外导性仅会产生暂时的导电性听力损失。
