Event Description
This report is being filed after the review of the following journal article: hajibandeh j., be a., and lee c.(2021), custom interlocking implants for primary and secondary reconstruction of large orbital floor defects: case series and description of workflow, journal of oral and maxillofacial surgery, vol.79 (xx), pages 2539.E1-2539.E10 (usa).The aim of this case series is to present a novel solution combining virtual surgical planning and the use of a 2-piece, interlocking patient specific implant to address the problem of limited surgical access.A total of 2 patients (case 1: 62-year-old male; case 2: 52-year-old male) were presented.Both patients were implanted with 2-piece patient specific titanium implant, using virtual surgical planning software (materialise, belgium) and the assistance of a clinical engineer (depuy synthes, ma) the bony architecture of the intact side of the orbit was mirrored onto the other side, for primary and secondary procedures, respectively.No complications for case 1.Reported complications were as follows: a 52-year-old male patient (case 2) underwent orif of his facial fractures through a bicoronal, transfacial (via the wound), and intraoral approaches on hospital day 5.The left orbital floor was accessed through the open wound and fixated using a preformed anatomic titanium plate (depuy synthes, raynham, ma).Ct scan on postoperative day 1 showed over-projection of the left zygomaticomaxillary complex (zmc) fracture.Decision was made to return to the operating room on hospital day 7 for revision of the left zmc and orbital floor fractures.The hardware from both fractures were removed and re-reduction of bony segments performed.The left orbital floor was again plated with a preformed anatomic titanium plate (depuy synthes, raynham, ma).After completion of fixation an intraoperative ct scan demonstrated satisfactory projection of the malar process and improved reduction of the orbital floor and zmc.The patient was evaluated in the outpatient setting 3 weeks postoperatively.He complained of ongoing primary gaze diplopia and on exam had enophthalmos and dystopia.Given his symptoms and lack of improvement we elected to perform a secondary orbital floor reconstruction.Preoperative ct scan was notable for a previously repaired left orbital floor defect measuring 3.0 x 3.7 cm.Volumetric measurements revealed a left orbital volume of 30.0 cm3 compared to 27 cm3 of the normal side.There was again concern regarding repair of such a large defect using a single plate, this time in the setting of scarring secondary to the initial trauma and prior operations.Using virtual surgical planning software (materialise, belgium) and the assistance of a clinical engineer (depuy synthes, ma) the intact right orbit was mirrored onto the left.A custom drill guide and 2 piece, interlocking patient specific titanium implant was fabricated to replicate the patient¿s anatomy (materialise, belgium) (fig 6).The patient was seen for outpatient follow-up until 2 months postoperatively.With the left orbital volume reconstituted, his enophthalmos and diplopia resolved and he clinically demonstrated appropriate globe projection and pupillary position.However, he briefly suffered from hsv keratitis of the left globe which was successfully treated with a course of antiviral therapy.This report is for an unknown synthes craniofacial plate/screws construct and patient specific implants.This is report 1 of 2 for complaint (b)(4).
