Post-operative orbital haematomas over a 12-year period. A description of three cases among 280 orbital procedures.

PURPOSE: To evaluate the incidence of orbital haematoma requiring surgical treatment following procedures including fracture repairs and orbital osteotomies over a 12-year period and to discuss their management.

METHODS

The records of all the patients who underwent a procedure involving the orbits from 1998 to 2011 were reviewed for evidence of post-operative haematomas. Medical data including clinical presentation, time between diagnosis and treatment, management and subsequent outcome were collected.

RESULTS

280 patients were included, 257 procedures for orbital or zygomato orbital fractures and 23 osteotomies for dysthyroid orbitopathy or malunited orbital fractures. Three cases (1.07%) of post-operative haematomas were observed as follows: 2/257 orbital fractures (0.77%) and 1/23 osteotomies (4.34%). All cases occurred in the early post-operative period of less than 6 h. No spontaneous loss of vision or pain was described by patients. All could be operated on as soon as the diagnosis was established; no CT-scans were required. Orbital drainage was successfully performed in all cases.

CONCLUSION

Post-operative orbital haematomas are uncommon complications. Diagnosis is based on a clinical examination, including pain, proptosis and alteration in visual acuity. Surgical treatment should be undertaken immediately following diagnosis.
