The Tessier Number 4 cleft is one of the rarest, most complex craniofacial anomalies that presents difficulties in surgical treatment. In this article, we report a case of simultaneous facial depression, eye displacement, and medial canthus deformity. In this case, the maxillary bony defect was reconstructed using computer-assisted design computer-assisted manufacturing (CAD-CAM) polyether-ether-ketone (PEEK) material, and the orbital floor defect was repaired with AO prefabricated titanium mesh. Additionally, the medial canthus was modified with canthopexy and a single Z-plasty flap...

Jacqueline M Jacobs, Eva L Chou, Nathan T Tagg
Silent sinus syndrome (SSS) is a rare disorder involving bony remodeling of the maxillary sinuses, including collapse of the orbital floor. It is typically unilateral and seen in the setting of chronic maxillary sinusitis. Patients present with enophthalmos and hypoglobus occasionally accompanied by diplopia. The condition is generally diagnosed with CT imaging and treated surgically. While SSS is most often reported as very slowly progressive, we report a patient with evidence of significant remodeling of the maxillary sinus over a period of 5...

Silent sinus syndrome (SSS) is a rare disease characterized by spontaneous enophthalmos and hypoglobus secondary to collapse of the orbital floor in patients with asymptomatic maxillary sinusitis. Radiographic findings include ipsilateral maxillary sinus opacification, lateralization of the uncinate and middle turbinate, and infundibular occlusion. We present a case series of three patients with clinical and radiographic evidence of SSS but without maxillary sinus opacification. Although uncommon, an aerated maxillary sinus in patients with unexplained enophthalmos, hypoglobus, and maxillary atelectasis should not exclude the diagnosis of SSS...

Management of orbital floor fracture remains the most debated topic in maxillofacial field. There are many approaches to reconstruct orbital floor fractures and restore orbital position and function, but many have the drawback of incomplete visualization, especially of the posterior part of the orbit. Pain, diplopia and enophthalmos are the most common presenting symptoms in patients who sustained orbital blow out fracture. The main aim in treating orbital fracture is to reduce the prolapsed orbital tissue and reconstruct the floor which will improve diplopia and enophthalmos...

Intraosseous hemangioma is an extremely rare tumor that accounts for 1% or fewer of all osseous tumors. The most common sites of its occurrence are the vertebral column and calvaria. Occurrence in a facial bone is very rare. The authors aim to report a case of the surgical treatment of intraosseous hemangioma occurring in the periorbital region, which is a very rare site of occurrence and to introduce our own experiences with the diagnosis and treatment of this condition along with a literature review. A 73-year-old male patient visited our hospital with the chief complaint of a mass touching the left orbital rim...

Orbital fractures are common. In patients where there is significant loss of the medial wall and orbital floor, anatomic prebent 3-dimensional plates allow efficacious restoration of orbital volume. However, the large size of these plates can result in technical difficulties with plate placement, especially in fractures with complete loss of 2 walls of the orbit. In this article, the authors review the pertinent anatomy of the bony orbit with respect to fracture and landmarks in fracture reduction. The authors also note the 3 most commonly encountered problems with the placement of anatomic plates: poor exposure, failure to identify the posterior ledge for the plate, and rotational issues with plate placement resulting in impingement...

Orbital roof defects are rare congenital osseous abnormalities that cause protrusion of intracranial contents into the orbit, resulting in a condition known as the orbital meningoencephalocele, a rare cause of pulsatile proptosis. We present a case of a 25-year-old lady, presented to us with complaints of left frontal headache, left eye protrusion and double vision from the left eye for the past three months. Her higher mental functions were intact. Local examination revealed non-axial pulsatile proptosis and an outward depression of the left eyeball along with diplopia...

INTRODUCTION: Up to 35% of orbital floor fractures extend to the medial wall. This results in restriction of both abduction and adduction, leading to horizontal diplopia. The greater the defect, the more pronounced the enophthalmos. AIM OF THE STUDY: The aim of the study was to determine the influence of concomitant medial wall defects on enophthalmos and diplopia, and the influence of intraoperative revision on the results of surgical reconstruction in patients with orbital floor fracture...

Isolated orbital wall fractures account for 4% to 16% of all facial fractures. Even a modest change in the position of the bony walls can have a significant impact on orbital volume and globe position. Alloplastic materials or autogenous bone grafts such as the antral maxillary wall can be used to reconstruct small- to medium-size orbital fractures. The main advantage of an antral wall graft is the intraoral approach with minimal morbidity. Nine patients underwent repair of orbital floor fractures using the extraoral and the intraoral antral wall approach...
