THIS REPORT IS BEING FILED AFTER THE REVIEW OF THE FOLLOWING JOURNAL ARTICLE: PEDEMONTE, C. ET AL. (2018), RECONSTRUCTION OF MEDIAL ORBITAL WALL USING A RETROCARUNCULAR APPROACH, JOURNAL OF CRANIO-MAXILLO-FACIAL SURGERY, VOL. 46, PAGES 1726-1730 (CHILE). THE PURPOSE OF THIS STUDY IS TO ANALYZE AND DESCRIBE THE USE OF THE RETROCARUNCULAR APPROACH FOR THE TREATMENT OF MEDIAL ORBITAL WALL FRACTURES. DURING JANUARY 2011 AND JANUARY 2017, A TOTAL OF 30 PATIENTS UNDERWENT ORBITAL RECONSTRUCTION TREATMENT WITH A RETROCARUNCULAR APPROACH TOGETHER WITH A TRANSCONJUNCTIVAL EXTENSION AND LATERAL CANTHOTOMY USING AN UNKNOWN SYNTHES TITANIUM MESH IMPLANT (MATRIXORBITAL). THE MINIMUM FOLLOW-UP WAS 6 MONTHS. THE FOLLOWING COMPLICATIONS WERE REPORTED AS FOLLOWS: 1 PATIENT PRESENTED A DELAYED COMPLICATION ON THE 5TH DAY AFTER THE OPERATION, DEVELOPING A CONJUNCTIVAL GRANULOMA ON THE CARUNCLE OF THE AFFECTED EYE SOCKET. THE GRANULOMA WAS ASSOCIATED WITH A STITCH TO THE INFERIOR OBLIQUE MUSCLE AND WAS REMOVED IN AN EXPLORATORY SURGERY WITHOUT NEED TO REMOVE THE MESH TO RESOLVE IT. 1 PATIENT DEVELOPED DELAYED ENOPHTHALMOS OF THE EYE SOCKET THAT WAS OPERATED ON AFTER THE 1ST SURGERY, MAKING A 2ND SURGICAL INTERVENTION NECESSARY TO RESTORE THE LOST ORBITAL VOLUME USING CUSTOMIZED IMPLANTS. 1 PATIENT, THOUGH UNRELATED TO THE TYPE OF APPROACH USED, DEVELOPED POST-TRAUMATIC GLAUCOMA AFTER 2 MONTHS. THIS IS FOR AN UNKNOWN SYNTHES TITANIUM MESH IMPLANT (MATRIXORBITAL). THIS IS REPORT 1 OF 2 FOR (B)(4).
