Faciomaxillary and ocular trauma is a common entity in most emergency and trauma units. We came across a 68-year-old female patient with a history of bull horn injury over the right eye. Examination revealed an empty orbital socket with unreliable perception of light present. Imaging showed that the eye had displaced posteroinferomedially to be lying in the ethmoid air cells in the nasal cavity. Under nasal endoscopic guidance, the eye was reposited back into the orbital socket and conjunctival sutures were taken to stabilize the position...

A 23-year-old male presented with a 3-month history of left purulent rhinorrhea, progressive nasal obstruction, and intermittent epistaxis. A fiberoptic examination revealed a large vascular polypoid mass completely filling the left nasal cavity. CT and MRI scans showed a large hypervascular mass involving the left nasal airway, maxillary antrum, and the anterior ethmoid cells. There was no bony erosion or contiguous spread, and the remaining sinuses, orbit, and cranial fossa were uninvolved. The patient underwent complete removal of the mass via an external lateral rhinotomy approach...

BACKGROUND: Anterior cranial fossa dural arterio-venous fistulas (DAVFs) represent 6% of all intracranial DAVFs; characteristically they show an aggressive behaviour with high risk of intracranial haemorrhage. Peculiar anatomical features, such as feeding by the ethmoidal arteries and the pattern of venous drainage (frequently with varices that mimic aneurysmal dilatation), can be evaluated in detail only by digital subtraction angiography (DSA), which represents the "gold standard" in the diagnosis of such cranial fistulas...

OBJECTIVES/HYPOTHESIS: Current rhinologic practice is devoid of minimally invasive procedures dedicated to the treatment of ethmoid sinusitis to improve ventilation and topical drug delivery. We have recently described a handheld spiral punch to create minimally invasive ethmoid punch sinusotomy (EPS) sites into the ethmoid bulla and basal lamella, which significantly increased irrigant access to the ethmoid sinuses in cadaver models. Here, we conducted a clinical feasibility study to determine the initial safety evaluation of EPS in chronic rhinosinusitis without polyposis (CRSsNP) patients with active ethmoid disease...

Oncogenic osteomalacia (OO) is an uncommon but treatable cause of osteomalacia related to tumor production of FGF23, usually caused by benign mesenchymal neoplasms. Paranasal sinus glomangiomas are a rare cause of OO, with only one previously reported case. Here we describe a second case (first reported in English) of paranasal sinus glomangioma-induced osteomalacia in a 42-year-old man. He presented with weakness and multiple spontaneous fractures, and was found to have an ethmoid sinus glomangioma with intracranial extension...

Spontaneous cerebrospinal fluid (CSF) leaks represent a clinical entity in which CSF rhinorrhea occurs in the absence of any inciting event. Spontaneous CSF leaks are associated with elevated intracranial pressure (ICP) or have underlying idiopathic intracranial hypertension (IIH). We report a cohort of patients who have undergone nasal endoscopic repair for spontaneous CSF leaks. We review our perioperative complications and the effectiveness of the nasal endoscopic approach to repair spontaneous CSF leaks...

Metastases in the paranasal sinuses are rare; renal cell carcinoma is the most common cancer that metastasizes to this region. We present the case of a patient with a 4-month history of a rapidly growing mass of the nasal pyramid following a nasal trauma, associated with spontaneous epistaxis and multiple episodes of hematuria. Cranial CT scan and MRI showed an ethmoid mass extending to the choanal region, the right orbit, and the right frontal sinus with an initial intracranial extension. Patient underwent surgery with a trans-sinusal frontal approach using a bicoronal incision combined with an anterior midfacial degloving; histological exam was compatible with a metastasis of clear cell renal cell carcinoma...

Orbital wall fracture reconstruction is usually recommended to prevent subsequent functional and esthetic complications. Mucocele development following such injuries or its management is recognized but rare sequelae. When they occur, they represent a diagnostic and management dilemma. The authors described a patient with orbital and ethmoidal mucocele. A 62-year-old female patient presented with progressive left exophthalmos 1 year following titanium mesh reconstruction of a medial orbital wall fracture. Computed tomography and magnetic resonance imaging demonstrated an encysted lesion encasing the mesh plate in the left orbit and extending into the ethmoidal sinus...

OBJECTIVE: According to evolutionary developmental (evo-devo) theory, the vomers are bones derived from the secondary palate. Growth of the palatine processes of the maxillae, including the precursors of vomer bones, results in midline fusion posteriorly to the primary palate, which forces the ascension of the vomer bones towards the primary nasal septum, formed by septal cartilage and the perpendicular plate of the ethmoid. According to this hypothesis, the anterior border of the vomer articulates with the posterior surface of the premaxilla in the incisive canal (IC)...

The frontal sinus outflow pathway is complex and can be influenced by the configuration of the uncinate process (UP). The UP can attach superior to the lamina papyracea, skull base, and middle turbinate. The factors associated with superior attachment remain unclear. This study analyzed the relationships between different types of superior UP attachment and characteristics of the surrounding structures including the agger nasi cell, skull base, and middle turbinate. This retrospective study utilized computed tomography images of 836 sides with identifiable sinus structure from 434 Taiwanese patients...
