ABSTRACT
Objective@#To analyze the clinical features and the pathogenetic law of traumatic optic neuropathy through epidemiologic study.@*Methods@#265 cases (275 eyes) with TON treated in Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University from April 1999 to August 2015 were retrospectively analyzed. Multiple Logistic regression analyses were used to evaluate potential prognostic factors on visual acuity.@*Results@#TON occured mostly in young (194/265, 73.21%) man (235/265, 88.68%), the majority of patients came from villages and towns (209/265, 78.87%). Traffic accident (197/265, 74.34%) remained the main etiology, with strike (36/265, 13.58%) and fall (17/265, 6.42%) as the common etiology. Most patients had head injuries. The effective rate of vision improvement was 53.45%(147/275). Multiple logistic regression analyses identified that initial visual acuity with light perception or better vision, optic canal fracture and orbital wall fracture were visual acuity key factors of TON (χ2 value was 24.674, 19.755, 9.175, respectively, all P<0.01), initial visual acuity with light perception or better vision was the protective factor on visual acuity recovery (OR=5.008, P<0.001), the presence of optic canal fracture and orbital wall fracture were the risk factors on visual acuity recovery (OR value was 0.110, 0.329, respectively, all P<0.01).@*Conclusions@#Ton occurs mostly in young man because of traffic accident. Visual impairment of TON is severe. The suitable preventive measures should be carried out according to its epidemiological features.
ABSTRACT
OBJECTIVE@#To observe the clinical and pathological features of adenoid cystic carcinoma(ACC) of external auditory canal (EAC, and analyze the possible factors related to prognosis.@*METHOD@#One out of 8 patients with ACC of EAC underwent tumor open biopsy. 5 patients underwent the extensive tumor resection, and 2 patients underwent the modified lateral temporal bone resection (1 of the 2 subjoined a total parotidectomy). Five patients received the postoperative radiotherapy.@*RESULT@#The time of follow up was 5-97 months. Two patients were loss to follow-up, 5 patients with disease free survival, and 1 patient survival with tumor.@*CONCLUSION@#In this study, ACC of EAC is more often observed in female. The most common clinical manifestations are otalgia and neoplasm which grows slowly. The disease has high misdiagnosis rate. Surgical treatment is effective for it.
