Critical appraisal of patient-specific implants for secondary post-traumatic orbital reconstruction.

In orbital reconstruction, a patient-specific implant (PSI) may provide accurate reconstruction in complex cases, since the design can be tailored to the anatomy. Several design options may be embedded, for ease of positioning and precision of reconstruction. This study describes a cohort of 22 patients treated for secondary orbital reconstruction with a PSI; one patient received two PSI.

[Loss of an eye as a result of an odontogenic infection].

A 50-year-old woman presented at the outpatient clinic of the department of oral and maxillofacial surgery with a severe swelling around the left eye 1 week after removal of the second molar in the upper jaw. Despite administration of antibiotics 2 days after the removal of the molar because of periorbital swelling, the inflammation spread to the intraorbital space with eventual loss of the left eye. Timely recognition of the symptoms of (the onset of) an orbital infection after dental treatment and immediate referral to an oral and maxillofacial surgeon and/or ophthalmologist for adequate treatment can be vision-saving.

Intraoperative imaging in orbital reconstruction: how does it affect the position of the implant?

Intraoperative imaging enables the surgeon to control the position of the implant during orbital reconstruction. Although it might improve surgical outcome and avoid the need for revision surgery, it may also increase the duration of the operation and the exposure to radiation. The goal of this study was to find out whether intraoperative imaging improves the position of the implant in reconstructions of the orbital floor and medial wall.
