Clinical Statistics And Analysis Of 191 Orbital Tumors Cases

Purpose: Statistically analyzing orbital tumors data counted by First Affiliated Hospital of Dalian Medical University, common types of orbital tumors in Dalian, incidence age, gender distribution, incidence of different years past to seek the inner laws in order to increase the systematic understanding of orbital tumors, improve the accuracy of its diagnosis and differential diagnosis, reflect the value of clinical diagnosis and differential diagnosis, provide idea for clinical doctors and the reference city’s orbital disease research.Method: Clinical data of 191 patients who were hospitalized to do orbital tumor resection and had determinate pathological diagnosis from Jan. 2004 to July 2014 in the department of Ophthalmology in First Affiliated Hospital of Dalian Medical University were collected and retrospectively analyzed, count the hospitalization age, gender distribution, and the constituent ratio and trends of histopathological classification, analyze and discuss the composition percentage of various orbital tumors in different time periods, and then make a comparative analysis about the statistical result.Result:(1) the type and proportion of orbital tumors:160 cases of benign tumors, 31 cases of malignant and the ratio of benign and malignant is 5.16 to 1. In histopathological classification, the top three benign orbital diseases are cavemous hemangioma in 55 cases(28.7%)、dermoid cyst in 26 cases(13.6%)、mixed tumor of the lacrimal gland in 22 cases(11.5). And the top three malignant tumors in 31 cases(16.2%)were non-Hodgkin’s lymphoma in 22 cases(70.9%)、mixed tumor of the lacrimal gland followed by(12.9%)and orbital metastasis in 3 cases(9.68%).(2) Gender: There are 107 males and 84 females. The ratio of male to female is 1.27: 1. the proportion of men is demonstrably higher than women.(3) Age: The patient age range is from 7 and a half months to 81 years, mean age(46.02 ± 19.47) years and the median ill age is 50 years old. In this study, the children’s group is benign lesions and dermoid cyst is the highest incidence for this group. For the youth and middle aged group, cavernous hemangioma is the most common disease. The youth and the middle age are two morbidity peaks groups. The number of people from Age 45 to age 59 takes the largest proportion(28.2%). Mixed tumor of the lacrimal gland is a common disease in elderly group. The frame transfer in 3 cases are all in elderly group.Conclusion: The total number of orbital tumor patients has increased from the year 2004 to 2014 in the First Affiliated Hospital of Dalian Medical University. The number of benign tumour and therioma are both increasing slowly. The inpatient shows an up trend in these 11 years. The proportion of Orbital lymphoma patients and mixed tumor of lacrimal gland patients shows a significant rise. Of all the orbital tumors in the First Affiliated Hospital of Dalian Medical University, the people from the age 45 to 59 has the highest case rate and more men than women. During the decade, the rank of orbital tumor disease remains unchanged in the First Affiliated Hospital of Dalian Medical University. The top five orbital tumors are cavernous hemangioma, dermoid cyst, mixed tumor of lacrimal gland, NHL and schwannoma. This suggests that the prevalence structure of orbital tumors is not changed.
