A 58-year-old Caucasian male presented with left periorbital oedema extending to the nasal area for 1 year along with nasal discharge for 1 month. Lab work was significant for positive cytoplasmic antineutrophil cytoplasmic antibodies. CT scan showed solid mass along the nasal soft tissue with bony nasal destruction. A CT scan of the thorax was performed to rule out granulomatosis with polyangiitis and showed multiple pulmonary nodules. Biopsies of the nasal mass and lung nodule were performed which showed fragments of fibrosis with spindle cell proliferation consistent with eosinophilic angiocentric fibrosis (EAF)...

Orbital lymphangioma is an infrequent benign cystic lesion manifesting in childhood and presenting with slowly progressive proptosis, and restriction of eye movements. Here we report a rare case of 8 year old male patient presenting with unilateral painful proptosis and subconjunctival hemorrhage with decrease of vision and restriction of eye movements. CT scan and MRI were done which revealed an intraorbital and intraconal cystic space occupying lesion. Fronto-orbito zygomatic craniotomy was done for orbital decompression and subtotal excision of tumor and blood evacuation...

To clarify the conflicting recommendations for care of blowout fracture (BOF), a prospective randomized study is required. Here, we present a prospective randomized pilot study on BOF. This article aimed to evaluate which computed tomography (CT) findings predict late functional and/or cosmetic symptoms in BOF patients with ≥ 1.0 mL herniation of orbital content into maxillary and/or ethmoidal sinuses. It also aimed to evaluate which patients with BOF would benefit from surgical treatment or observational follow-up...

PURPOSE: To longitudinally evaluate for changes in globe position as part of the natural aging process. METHODS: A Cleveland Clinic Foundation imaging database of all head imaging scans performed from 1995 to 2017 was used to identify adults with normal orbits undergoing imaging studies at least 20 years apart. A total of 100 patients (200 globes) who had CT or MRI scans were studied. Globe position was determined by measuring the distance from the anterior aspect of the cornea to the zygomaticofrontal processes baseline...

INTRODUCTION: Treatment decisions for fractures of the orbital floor are based on clinical appearance, ophthalmological examination, and computed tomography (CT) scans. In extensive fractures, decisions are easily made between conservative and surgical treatment. However, objective parameters are rare in inconclusive cases. MATERIALS AND METHODS: Our retrospective study included 106 patients with unilateral isolated orbital floor fractures. Correlations between preoperative ophthalmological examinations and specific CT parameters were performed...

Craniofacial bone lesions involving the orbit are often associated with symptoms, including proptosis, orbital dystopia, and overall facial asymmetry. Fibrous dysplasia and osteoma are the 2 most commonly observed bone tumors in the craniofacial area. Nine patients with either craniofacial fibrous dysplasia or osteoma and an unacceptable aesthetic appearance were treated from January 2015 to July 2016. All patients underwent preoperative craniofacial 3-dimensional computed tomographic (CT) scanning, and standard photographs were obtained...

Trapdoor fractures are common in children because of elastic nature of the pediatric bone. Clinical signs and radiological evidence in these cases may be minimal.This study involves a 14-year-old girl who sustained blunt trauma to her left eye. Initial investigation, for pure orbital floor fracture included computerized tomography (CT scan) of the orbit, did not show any evidence of incarcerated rectus muscle. She had no limitation of extraocular movements nor enophthalmos. Following conservative treatment, she had a left persistent orbital pain and left monocular diplopia...

Orbital reconstruction in cases of trauma is usually performed using the unaffected side orbital volume as a reference, but this measurement does not fully consider the anatomical characteristics of orbital surfaces. We propose a novel procedure based on the registration of 3D orbital segmented surfaces. Reconstructed orbits from 20 patients and healthy orbits from 13 control subjects were segmented from the post-operative CT-scans. The 3D orbital model from the unaffected orbit was "mirrored" according to the sagittal plane and superimposed onto the reconstructed one, with calculation of volumes, asymmetry index and point-to-point RMS (root mean square) distances...

INTRODUCTION: Unilateral coronal synostosis (UCS) is a complex craniosynostosis, combining malformations of the upper (frontal bone, orbito-naso-frontal bandeau (ONFB) ) and the middle thirds of the face. In our centre, the surgical correction consists in the repositioning of the ONFB in front of the zygomaticofrontal suture on the affected side. Defects in the corrections have been observed post-operatively for some patients with a persistent asymmetry in the side walls of the orbits...

OBJECTIVE: Mesenchymal stem cells (MSCs) derived from nasal mucosa are featured by high division and differentiation capacity, with large nuclei, obvious nucleoli and weak cytoplasmic basophily. Imaging examination, typically CT scan, is the gold standard for the diagnosis of orbital fracture. METHODS: We isolated MSCs derived from goat nasal mucosa and built the calcification model so as to investigate the repair mechanism of nasal mucosa-derived MSCs in orbital fracture...

We report of a case of Graves' ophthalmopathy presented solely with symptoms of the eyes with normal thyroid function tests and negative immunoreactive TSH receptor autoantibody. 40-year-old male was referred to our hospital due to 2-month history of ocular focusing deficit without any signs or symptoms of hyper- or hypothyroidism. Serum thyroid function tests and 99m Tc uptake were both within the normal range. Anti-thyroid autoantibodies were all negative except for the cell-based assay for serum TSH receptor stimulating activity...

Craniosynostosis is caused by premature fusion of one or more cranial sutures, restricting skull, brain and face growth. Nonsyndromic craniosynostosis could disturb the proportions of face. Although morphometric diameters of nasal cavity in healthy children are already known, they have not been established yet in children with nonsyndromic craniosynostosis. The aim our study was to check whether diameters of bone structures of nasal cavity in children with nonsyndromic craniosynostosis measured in CT are within normal range...

PURPOSE: Despite the advantages and broad applications of alloplastic resorbable implants, postoperative radiological control is challenging due to its radiolucency. The aim of the present study was to evaluate the radiographic visibility of newly developed materials for orbital floor reconstruction. MATERIALS AND METHODS: The radiographic visibility of four different material combinations consisting of poly-(L-lactic acid)/poly-glycolic acid (PLLA/PGA) or poly(D,L-lactic acid) (PDLLA) enriched with magnesium (Mg), hydroxyapatite (HA) or β-tricalcium phosphate (β-TCP) with various layers of thicknesses (0...

INTRODUCTION: Functional endoscopic sinus surgery for frontal sinus disease has obviated the need for external approaches. Special circumstances such as acute infection with orbital involvement or significant lateral sinus disease frequently require adjunct access. We describe the clinical outcomes of a combined upper eyelid crease and endoscopic approach for lateral frontal sinus disease with orbital extension. METHODS: A retrospective case series of 7 patients who underwent a combined lid crease approach for frontal sinus disease with orbital extension between April 2012 and October 2016 was performed...

A 5-year-old boy was accidentally injured by a compressed air blast to his right eye and developed periorbital and subconjunctival emphysema and proptosis subsequently. CT scan showed periorbital subcutaneous and intraorbital emphysema around the right eye, as well as intracranial and cervical emphysema without frank fractures in orbital bones. He was examined under sedation, and the subconjunctival air was aspirated. He was also prophylactically treated with topical and systemic antibiotics to prevent infection...

A 33-year-old man was admitted to hospital with a butter knife stuck in his head after having attempted to commit suicide by forcing the knife through his skull. Physical examination revealed a stable patient with only minimal associated haemorrhage. A CT scan revealed, that the penetrating knife had passed through the sphenoid bone, the posterior orbit and the ethmoid cells and ended in the contralateral nasal cavity. The knife was removed by its own trajectory. After surgery, the patient was neurologically intact with normal sight and well-functioning eye movements, and he made a full recovery...

Intentional cranial deformations are the result of external mechanical forces exerted on the skull vault that modify the morphology of various craniofacial structures such as the skull base, the orbits and the zygoma. In this controlled study, we investigated the 3D shape of the orbital inner mould and the orbital volume in various types of intentional deformations and in adult non-operated scaphocephaly - the most common type of craniosynostosis - using dedicated morphometric methods. CT scans were performed on 32 adult skulls with intentional deformations, 21 adult skull with scaphocephaly and 17 non-deformed adult skulls from the collections of the Muséum national d'Histoire naturelle in Paris, France...

PURPOSE: Craniofacial microsomia (CFM) is characterized by malformations of structures derived from the first and second pharyngeal arches. The orbit is variably affected. The purpose of this study was to determine whether there is a difference in orbital volume between affected and unaffected sides in patients with unilateral CFM. The specific aims were to 1) measure orbital volume, 2) compare affected and unaffected sides, 3) evaluate the correlation between clinical evaluation of orbital size and volumetric measurement, and 4) determine whether there is a correlation between orbital volume and severity of mandibular deformity...
