INTRODUCTION: Cranial defects following intra-osseous tumor removal may be large and require adequate reconstruction. CAD/CAM implants have been used for years to achieve an optimal cosmetic result. The disadvantage is that such implants require a second surgery. A preoperative virtual planning of resection margins and the simultaneously fabrication of the cranioplasty could be a possibility to subsume the steps tumor resection and cosmetic restoration to a single procedure. METHODS: We present two cases of patients with complex intra-osseous spheno-orbital meningioma...

INTRODUCTION: Craniosynostosis is the premature fusion of one or more of the cranial sutures and can occur as part of a syndrome or as an isolated defect. Pansynostosis is a rare form of craniosynostosis that involves premature fusion of all the cranial sutures (coronal, sagittal, metopic, and occipital). Particularly in cases of late presentation, there are heightened clinical concerns, both functional and aesthetic. In untreated cases of pansynostosis and increased intracranial pressure, optic nerve damage progresses to optic atrophy and then blindness...

A 25-year-old man with Type 1 diabetes mellitus experienced rapid visual decline and was scheduled for right cataract surgery. At the time of administering an inferotemporal retrobulbar block, a white discharge appeared spontaneously on the surface of the globe. Superotemporally a cyst was found and its contents were subtotally evacuated. Microscopically, eosinophilic, acellular material with chatter artifact and small vacuoles was detected and initially thought to represent a lens choristoma. This material stained moderately with the periodic acid Schiff method and was focally Congo red positive without apple green birefringence; it also stained blue with the Masson trichrome method...

Background Ameloblastomas are a rare tumor entity accounting for only 10% of all odontogenic tumors. They mostly originate from the mandible. Only a few cases are known to grow aggressively and to invade the orbit, nasal cavity, or even the brain. Patient and Methods/Case Report We present the case of a 57-year-old patient who was admitted with a huge tumor involving the nasal cavity, the left maxilla, and the anterior fossa. Histologic diagnosis was made by biopsy. A combined two-stage neurosurgical maxillofacial approach was planned...

Surgical correction of premature fusion of calvarial sutures involving the fronto-orbital region can be challenging due to the demanding three-dimensional (3D) anatomy. If fronto-orbital advancement (FOA) is necessary, surgery is typically performed using resorbable plates and screws that are bent manually intraoperatively. A new approach using individually manufactured resorbable implants (KLS Martin Group, Tuttlingen, Germany) is presented in the current paper. Preoperative CT scan data were processed in iPlan (ver...

BACKGROUND: Trigonocephaly is caused by metopic suture synostosis. It is treated by fronto-orbital remodeling, not only to correct the deformity but also to prevent intracranial hypertension, the reported prevalence in trigonocephaly of which ranges from 0 to 33 percent. To support treatment analysis and the design of a treatment protocol for intracranial hypertension in these patients, the authors wished to more accurately quantify the prevalence of preoperative and postoperative intracranial hypertension in a large patient cohort...

OBJECTIVE: To examine the efficacy of spheno-orbital meningioma (SOM) resection aimed at symptomatic improvement, rather than gross total resection, followed by radiation therapy for recurrence. METHODS: A retrospective review of all patients having undergone resection by the senior author (KOL) between 2000 and 2016 was performed. Demographics, operative details, post-operative outcomes, recurrence rates and radiation treatment plans were analyzed. Statistical analysis was performed to assess for factors affecting recurrence (Fisher's exact and student's t-test), changes in exophthalmos index (student's t-test) and progression free survival (Kaplan-Meier and log rank)...

INTRODUCTION: Fibrous dysplasia (FD) is a non-neoplastic developmental fibro-osseous disease. It represents 2.5% of all bone tumors and 5% to 7% of the benign bone tumors. Orbitocranial region is involved in about 20% of the patients. The main presentations are craniofacial deformity and headache. Loss of vision is the most devastating result of this disease. There is no medical treatment to cure or prevent FD. Radiation therapy is contraindicated. Surgery for the orbitocranial FD is often challenging because of the proximity of neurovascular and ocular structures...

Jinyong Cho, Jaeyoung Ryu
Blow-in fracture of the zygomaticomaxillary complex that was displaced into the orbital cavity could be associated with ophthalmologic injuries, ranging from visual acuity to ocular motility limitation. Appropriate reduction and realignment of the fractured bone is necessary as early as possible for recovery of function and esthetics. However, limitation of accessibility and visibility makes it difficult for delicate surgery and increases the risk of damage of adjacent anatomic structures, such as optic nerve and extraocular muscles...
