In the treatment of orbital floor fractures, bone is ideally regenerated. The materials currently used for orbital floor reconstruction do not lead to the regeneration of bone. Our objective was to render polymeric materials based on poly(trimethylene carbonate) (PTMC) osteoinductive, and to evaluate their suitability for use in orbital floor reconstruction. For this purpose, osteoinductive bip...

Orbital blowout fractures are common sequelae of facial trauma. For their treatment, it is now possible to make three-dimensional (3D) implants on the basis of computed tomography (CT) images, using rapid prototyping and to bend the implants preoperatively in the desired shape. However, in orbital fracture, the unique anatomy of the orbit makes the process of fitting and aligning such implants ...

Experience in the management of 77 isolated orbital floor fractures is presented. The transconjunctival approach was used exclusively to access the orbital floor and lyophilized dura and cartilage were used to reconstruct the floor, when indicated. Follow-up for an average of 36 months showed excellent cosmetic and functional results. A 20% complication rate was noted, which compares favorably ...

A 79-year-old man presents with signs of an orbital mass. A CT scan revealed a large maxillary mucocele eroding through the orbital floor. Surgical drainage of the mucocele and conservative postoperative care, returned all ophthalmic signs to normal and bony remodelling of the orbital floor was demonstrated. Maxillary mucoceles should be assessed by both ENT and Ophthalmic surgeons. Postoperati...

introduction penetration of a bicycle brake handle into the orbit is a rare and serious type of trauma. globe subluxation due to such trauma has not been previously reported. case presentation a 10-year-old girl presented after falling from a bicycle, which resulted in the handbrake penetrating her right upper eyelid. on examination, the globe was subluxated anteriorly, there was no light perce...

The aim of the study was to assess factors leading revision surgery and implant position primary orbital fracture reconstructions. A retrospective cohort included patients who underwent floor and/or medial wall reconstruction for recent trauma. Demographics, type, implant-related variables, postoperative were analyzed. overall rate 6.5% (15 232 surgeries). highest in combined midfacial fracture...

objective:  to report the outcome of subciliary approach for inferior orbital rim fractures in a series of iranian patients. methods:  this was prospective cross-sectional, being performed during a 12-month period during 2013 in plastic surgery department of emamreza hospital of mashhad. we included 12 patients with traumatic inferior orbital rim fractures who underwent surgical repair through ...

BACKGROUND The aim of orbital wall reconstruction is to reestablish anatomically exact orbital volumes to avoid long-term complications. Navigation could facilitate complex reconstructions. METHODS Quality of the orbital reconstruction (n=94) was measured based on (A) volume changes and (B) on 3D shape deviations compared to the unaffected side. Volume analysis included segmentation of the or...
