Sympathetic ophthalmia (SO) is a rare, diffuse, bilateral, and granulomatous nonnecrotizing panuveitis that may follow intraocular penetrating trauma. Our aim is to report a rare case of SO following orbital exenteration. Orbital exenteration was performed on a 48-year-old african female due to conjunctival keratinizing squamous cell carcinoma with intraocular involvement of the left eye. Five days after the uneventful procedure, the patient presented signs and symptoms compatible with SO. Key differential diagnoses were excluded, and prompt and aggressive immunosuppression was started with a favourable but slow clinical response...

INTRODUCTION: Cerebrospinal fluid (CSF) rhinorrhea results from an abnormal communication of the dura mater to the nasal mucosa. The majority of cases of CSF rhinorrhea are the result of trauma or surgery involving the skull base. Spontaneous CSF rhinorrhea is a rare clinical entity with increased risk of ascending infection. Delay in diagnosis places the patient at risk of developing meningitis. CASE PRESENTATION: A 36-year-old African American female with significant medical history of obesity and hypertension presented to the emergency department with headache, altered level of consciousness, fever, and neck stiffness...

There are various causes that can lead to compressive optic neuropathy. We present here orbital apex cyst as an unusual cause of compressive optic neuropathy in a 49-year-old male. He presented with 2 weeks painless loss of vision in the left eye with left-sided headache. He had had left functional endoscopic sinus surgery for left nasal polyps 4 years earlier. Magnetic resonance imaging of brain and orbit revealed a left discrete orbital nodule, possibly orbital cyst or mucocele, which was compressing on the left optic nerve...

To describe the novel use of a bilayer dermal substitute to reconstruct exenterated orbits. A retrospective chart review was performed in the practices of two surgeons (RET and PDL) of all patients who had undergone orbital exenteration between April 2014 and June 2016 and whose subsequent reconstruction included lining the socket with Integra bilayer. Patient demographics, pathologic diagnoses, surgical and post-operative complications, graft integrity, and patient acceptance were recorded. The charts of 7 patients (4 men and 3 women, ages 60-87 years) were reviewed...

While sharp, penetrating trauma is often associated with group A Streptococcus (GAS) infections and subsequent necrotizing fasciitis (NF) and streptococcal toxic shock syndrome (STSS), there are scant reports in the oral and maxillofacial surgery literature regarding blunt, non-penetrating trauma in association with these conditions. With a clinical course that initially appears relatively benign following blunt trauma, NF can progress swiftly through the fascial planes and may quickly become life-threatening if the oral and maxillofacial surgeon fails to recognize some of the critical pathognomonic signs...

PURPOSE OF REVIEW: The current study reviews the recent literature on pediatric orbital blowout fractures and provides guidelines on their management. RECENT FINDINGS: The most common problem among patients requiring surgical revision of a previously repaired orbital floor fracture is an improperly placed orbital floor implant, usually erroneously placed under the posterior bony ledge. Although the transconjunctival incision can be combined with a lateral canthotomy and cantholysis, excellent surgical exposure can be obtained without the need for these latter relaxing maneuvers...

Retinoblastoma is the most frequent intraocular tumour in childhood. The definitive treatment is enucleation. The management of the anophthalmic socket consists in the use of a plastic implant. The problem is that they are expensive and they usually extrude. The use of dermal-fat grafts minimises the hemi-facial hypoplasia. They usually grow with the face, and help to expand the orbital bones, thus avoiding the psychological and physical consequences. OBJECTIVE: To determine if there is hemi-facial hypoplasia, using MRI images after the use of a dermal-fat implant in patients enucleated for RB...

We report an unusual presentation of an orbital cavernous hemangioma in a 26-year-old female, who noted sudden redness and swelling of the left eye (LE) on waking up. At presentation, upper eyelid edema with periorbital ecchymosis and subconjunctival hemorrhage were noted in the LE. Although there was transient symptomatic relief with topical medications, blurring of vision developed in the LE. When seen 10 days later, the patient's LE showed axial proptosis. Magnetic resonance imaging revealed an intraconal soft tissue mass in the superomedial quadrant of the left orbit...

We report the first description of oculocardiac reflex elicited with injection of local anesthetic in an empty orbit, and highlight clinical indicators for patients that may be at risk for an exaggerated oculocardiac reflex. We describe a patient with prior head and eye trauma treated for anophthalmic socket reconstruction at an outpatient eye surgery center. Injection of local anesthetic into the empty orbit induced an extended sinus arrest. This exaggerated response was avoided in a subsequent surgery by pretreatment with high-dose anticholinergics...

BACKGROUND: Tufted angiomas (TAs) are uncommon benign vascular tumors mostly located cutaneously or subcutaneously in the skin of the neck and upper trunk, which appear during childhood and grow slowly. TAs are a variant of lobular capillary hemangiomas. This is the first study to provide an overview of the current literature in combination with the authors' own clinical experience on this rare entity in the head and neck area with non-dermatological localization. METHODS: A selective Medline and Google Scholar database search was performed...

PURPOSE: Analysis of symmetry represents an essential aspect of plastic-reconstructive surgery. For cases in which reference points are either not fixed or are changed due to corrective intervention the determination of a symmetry axis is sometimes almost impossible and a pre-defined symmetry axis would not always be helpful. To assess cranial shape of surgical patients with craniosynostosis, a new algebraic approach was chosen in which deviation from the optimal symmetry axis could be quantified...

Many types of ocular surgery can cause diplopia, including eyelid, conjunctival, cataract, refractive, glaucoma, retinal, and orbital surgery. Mechanisms include direct injury to the extraocular muscles from surgery or anesthesia, scarring of the muscle complex and/or conjunctiva, alteration of the muscle pulley system, mass effects from implants, and muscle displacement. Diplopia can also result from a loss of fusion secondary to long-standing poor vision in one eye or from a decompensation of preexisting strabismus that was not recognized preoperatively...

BACKGROUND: Foreign bodies within the sinuses, orbit, and skull base (FBSOS) are rare; hence, diagnosis and management guidelines are lacking. Endoscopic sinus surgery (ESS) removal is preferred because of the less invasiveness and minimal morbidity. This study was designed to summarize clinical experience with ESS management of FBSOS. METHODS: We retrospectively reviewed clinical manifestations, imaging findings, treatment, and outcomes in consecutive patients with ESS removal of FBSOS between 2004 and 2015 at a tertiary academic medical center...
