Orbital preservation in maxillectomy

Twenty-eight previously untreated patients with squamous carcinoma of the maxillary sinus underwent maxillectomy with preservation of the orbital contents at the M. D. Anderson Cancer Center between 1971 and 1986. Eighteen patients had part or all of the orbital floor resected; nine patients were treated with radiotherapy, and nine had surgery only. Only 3 of 18 patients in this group (17%) retained significant function in the ipsilateral eye. Furthermore, local recurrence in this group was common (44%), regardless of whether postoperative radiotherapy was used. Ten patients retained the bony orbital floor; if the radiation fields did not include the eye, problems were minimal. Strong consideration should be given to orbital exenteration at the time of surgery, when the orbital floor is resected-especially if postoperative radiation fields will include the eye.
