    Many techniques of orbital decompression have been used in the treatment of Graves ophthalmopathy. Recently endonasal endoscope surgery was introduced in the orbital decompression, as an isolated technique, or combined with existing techniques hopefully to give better visualization of medial wall and a lower incidence infection when the medial wall is acessed. AIM: To evaluate orbital decompression combined with endoscope in prevention of bacterial infection, we relate three cases of assyntomatic patients with computer tomography control of facial sinus presenting opacification of maxillary or frontal sinus. STUDY DESIGN: Clinical Prospective. MATERIAL AND METHOD: 16 patients with 18 orbita procedures underwent orbital decompression, in the Ophthalmology Department at the Escola Paulista de Medicina-UNIFESP an orbital decompression was obtained by combined technique using endonasal access with an endoscope. RESULTS: Four patients during postoperative CT scan presented assymtomatic opacification of the maxillary or frontal sinuses. CONCLUSION: A combination of endoscopy in orbital decompression by external approach showed the effectiveness in prevention of sinusitis clinically manifested and its complications, although a longer time of follow-up is needed to understand better radiological findings 22% presented opacification of the sinuses and their consequences.

    Perdas auditivas em paralisia facial periférica após cirurgia de descompressão

    Facial paralysis can result from a variety of etiologies; the most common is the idiopathic type. Evaluation and treatment are particularly complex. The treatment of acute facial paralysis may require facial nerve decompression surgery. Any structure near the path of the facial nerve is at risk during transmastoid decompression surgery. AIM: This is a retrospective study, carried out in order to evaluate hearing loss after transmastoid decompression and how idiopathic cases evolved in terms of their degree of paralysis in the last 15 years. MATERIALS AND METHODS: We selected the charts from 33 patients submitted to transmastoid facial nerve decompression in the past 15 years and we assessed their hearing loss and facial paralysis. RESULTS: There was a high percentage (61%) of patients with some degree of hearing loss after the procedure and in all cases there was improvement in the paralysis. DISCUSSION: The values obtained are similar to those reported in the literature. One possible explanation for this hearing loss is the vibration transmission by drilling near the ossicular chain. CONCLUSION: The surgical procedure is not risk free; indications, risks and benefits should be explained to patients through an informed consent form.
