A 51-year-old man who had undergone right orbital decompression 5 months earlier developed a meningoencephalocele extending in the right sphenoid sinus through a skull base defect of the right ethmoid, sphenoid, and frontal bones. The authors report the third case to their knowledge of meningoencephalocele with cerebrospinal fluid leak after orbital decompression and discuss its management and measures that can be taken to prevent this rare but serious complication.

Mucocele of the paranasal sinuses is a rare disease with slow evolution. It is a benign, encapsulated and destructive formation filled with mucous fluid and tapistrated with respiratory epithelium. Of all the paranasal sinuses, the sphenoid sinus is affected in only 1-7% of the cases. We present two cases of mucocele of the sphenoid sinus involving the posterior ethmoidal cells. We consider here their clinical presentation, use of neuroimaging in the diagnosis, surgical care and postoperative results. Both patients presented with a history of persistent headache and in addition, one of them had a paresis of the right oculomotor and abducens nerves...

BACKGROUND: Frontoethmoidal schwannomas are rare. No case manifesting exertional cerebrospinal fluid (CSF) rhinorrhea has ever been reported to the best of our knowledge. CASE DESCRIPTION: In this report, we describe an extremely rare case of frontoethmoidal schwannoma extending through the olfactory groove (OG) with exertional CSF rhinorrhea as the initial symptom. A 50-year-old woman was presented to our clinic for frequent nasal discharge on exertion. A postcontrast computed tomographic scan demonstrated heterogeneously enhanced tumor from the anterior cranial fossa to the anterior ethmoid sinus...

Chondromyxoid fibroma (CMF) is a rare benign tumor, usually arising in the metaphysis of long bones in young adults. Occurrence in craniofacial bones presents a particular diagnostic challenge given its unusual location and resemblance to malignant mimics. We describe the clinicopathologic features of 25 cases of craniofacial CMF identified between 1999 and 2017. Patients were 14 men and 11 women, with median age of 44 years (range, 5 to 83 y). Sites of involvement were sphenoid (7), ethmoid (5), maxilla (3), occipital (2), nasal septum (2), palatine (2), temporal (2), orbit (1), and undisclosed skull (1)...

The advent of titanium hardware, which provides firm three-dimensional positional control, and the exquisite bone detail afforded by multidetector computed tomography (CT) have spurred the evolution of subunit-specific midfacial fracture management principles. The structural, diagnostic, and therapeutic complexity of the individual midfacial subunits, including the nose, the naso-orbito-ethmoidal region, the internal orbits, the zygomaticomaxillary complex, and the maxillary occlusion-bearing segment, are not adequately reflected in the Le Fort classification system, which provides only a general framework and has become less relevant in contemporary practice...

PURPOSE: The use of technology to aid in assessment, planning, and management of complex craniomaxillofacial injuries is increasingly common. Preoperative computed tomography (CT) evaluation is considered the standard of care, and intraoperative imaging is becoming increasingly accessible. Limited data exist regarding the implication of intraoperative CT on decision making in the management of all sites of facial fractures. The purposes of this study were to characterize the use of an intraoperative CT scanner for craniomaxillofacial surgery within our institution, to quantify the effect of intraoperative CT on surgical decision making, and to attempt to provide guidance on when to use this technology...

ENT infections are the most common childhood infections and the leading causes of antibiotic prescriptions. These infections are mainly due to viruses and most of them (even if bacterial species are implicated) resolve spontaneously. Therefore, the first message is to not prescribe antibiotics in the following situations: common cold, non-streptococcal pharyngitis, laryngitis, non-purulent otitis media, etc. For sore throat/pharyngitis, the antibiotic treatment decision is based mainly on the use of group A streptococcus rapid diagnostic tests...

Computed tomography (CT) images have been used in very few studies on distances to the ethmoidal arteries in the orbit. Most other studies have included direct measurements on cadavers and frequently quote the 24-12-6 mm rule to describe distances from the anterior lacrimal crest to the anterior and posterior ethmoidal foramina (AEF and PEF), optic canal (OC), respectively. However, the large interindividual variation of distances renders absolute values less applicable in a clinical setting. Preoperative measurements on CT images may provide more precise distances than absolute rules and thus lead to safer orbital surgery...

Osteomas are slow-growing, benign bony tumors. Most are asymptomatic. Paranasal sinus osteoma in the pediatric population is rare; hence, there are few reports of symptomatic osteomas. The authors report the case of a giant ethmoid sinus osteoma in an 11-year-old girl who presented with diplopia and proptosis. Total excision and reconstruction of the medial orbital wall were performed via a coronal approach. The postoperative period was uneventful, the child's vision improved, and a good cosmetic result was obtained...

We present the case of an adult white man found dead in a psychiatric institution with fine white powder (monoammonium phosphate) deposited over the entire face after he insufflated the contents of a dry chemical fire extinguisher. Fine white powder was present within the mouth and sinuses and lined the upper airways. On opening the thoracic cavity, approximately 500 g of fine white powder was present within the right thoracic cavity. The esophagus was ruptured. Traumatic emphysema of the posterior sternum wall was present (pneumomediastinum)...

BACKGROUND: Knowledge of the position of the ethmoidal arteries is critical to enable safe endoscopic sinus and orbital surgery. The presence of a third or "middle" ethmoid variant has recently become more relevant as endoscopic intraconal surgery continues to advance. The purpose of this study was to quantify the presence of supernumerary (ie, over 2) ethmoid foramina in different ethnicities and genders. METHODS: Morphometric osteologic measurements were performed in 273 orbits...

Background: Sphenoethmoid cells may be above the sphenoid sinus with/ or without con-tact to optical nerve. Although sphenoethmoid cells are theoretically considered to possibly influence the sphenoid sinus volume, we could not find any study in the literature on this issue. Aims: The aim of our study was to detect sphenoethmoid cells and measure the sphenoid sinus vol-ume using multiplanar computerized tomography and also investigate the correlation between the presence of sphenoethmoid cells and the sphenoid sinus volume...

Chronic nasal dysfunction is a clinical concept in the diagnostic and therapeutic management of sinonasal diseases, based on the evo-devo theory of formation of the nose according to which the nose is not a single organ but rather an association of three organs: olfactory nose, respiratory nose and paranasal sinuses. In chronic nasal dysfunction theory, etiological diagnosis takes account of the possible pathophysiological independence of nasal symptoms, in accordance with the different origins and physiology of the three organs constituting the nose...

Trauma to the Naso-orbito-ethmoid region invariably results in detachament of Medial Canthal Tendon. The shape of medial canthus is of important esthetic and functional concern. Accurate reposition of the medial canthus is important to achieve normal form and function. The various available techniques advocate open approach leaving an obvious scar in the esthetically prominent region. This technique intends to address these fractures through a closed approach with the possibility to make finer adjustments as and when required...

BACKGROUND: The complexity of the frontal sinus drainage pathway (FSDP) can be challenging even for expert surgeons. Several classifications have been proposed to simplify the understanding of FSDP, whose anatomical variability can be simplified based on the knowledge of its developmental mechanisms. METHODS: Cone-beam computed tomography studies performed at the Unit of Radiology of the University of Brescia between March and November 2012 were retrospectively analyzed...

The endoscope has revolutionized the diagnosis and treatment of diseases of the nose and paranasal sinuses. Endoscopic sinus surgery (ESS), like all minimally invasive surgery, is designed to combine an excellent outcome with minimal patient discomfort. Successful outcome with minimal complications can only be achieved with good knowledge of the endoscopic anatomy, appropriate training in the procedure and the understanding of the anatomical variations. The intraoperative complications of ESS are bleeding and injury to surrounding structures commonly the orbital structures and fovea ethmoidalis...

The formation of an intracranial abscess secondary to sphenoid sinus occlusion after nasoseptal flap skull base reconstruction has not been previously described. We report such a case that occurred at our institution in a 23-year-old man who underwent flap reconstruction for a cerebrospinal fluid leak. We determined that occlusion of the sphenoid sinus outflow might have played a role in this complication. The patient was treated via a combined surgical and medical approach that entailed a bur-hole craniotomy and endoscopic debridement followed by administration of an intravenous antibiotic...
