Abstract
|
|
|
Diverse pathological types of tumor are known to occur in the orbital space, although not common. Object of this study
was to evaluate and analyze the characteristics of these uncommon tumors that were undertaken operatively in past ten
years. Moreover, choice of surgical approaches for various types of tumor was reconsidered. A total of 55 cases operated
in our institution from 1988 to 1998 were included in this study. Primary intraocular tumors, e.g., retinoblastoma, and
those arising from appendages were excluded. Age distribution, sex ratio, symptomatology, radio- histopathological
types, and surgical methods with their results were analysed. Age distribution was 1 to 60 years with average of 29.1
years. Male to female ratio was 26：29. The most common symptom was exopthalmos(40%). Radiologic findings were
related to types of pathology. Pseudotumor(16.3%), dermoid(14.6%), meningioma(10.9%), neurilemmoma(10.9%),
hemangioma(9.1%) were among more common histologic types. Various surgical approaches were applied according to
types and locations of tumors including two-step supraorbital approach. There were 8 cases of recurrence in whom
reoperations were necessary. Most of postoperative cosmetic results were acceptable. Wide variety of histologic types of
orbital tumors can be seen with recurrences in some cases. Thus, careful selection of surgical plan seems to be mandatory for good functional outcome.
