A sinonasal mucocele can develop after the obstruction of a sinus ostium, which can occur secondary to trauma, infection, a neoplasm, or an iatrogenic cause. These mucoceles typically arise in the frontal and ethmoid sinuses. Sinonasal mucoceles are epithelium-lined cysts that can gradually expand to fill a paranasal sinus. They can present with ophthalmologic, rhinologic, and neurologic symptoms. There are reports in the literature of sinonasal mucocele development after radiation for nasopharyngeal carcinoma...

Typical transcranial approaches are insufficient for adequate visualization and resection of skull base tumors. Different approaches with multiple modifications have been attempted. Here, we describe a new approach for a lesion that is central and hard to treat by conventional craniotomy and successful reconstruction with calvarial bone graft and titanium mesh plate. A 69-year-old female patient presented with recurrent meningioma. The tumor had invaded the frontal lobe, right supraorbital rim, and ethmoidal bone...

REVIEW
Yong Hyun Kim, Baek-Kyu Kim
Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele formation or chronic frontal sinusitis. Therefore, evaluation of FSOT is of clinical significance, with FSOT being diagnosed mostly by computed tomography or intraoperative dye. Several options are available to surgeons when treating FSOT injury, and they need to be familiar with these options to take the proper treatment measures in order to follow the treatment principle for FSOT, which is a safe sinus, and to reduce complications...

REVIEW
Jeenam Kim, Hyungon Choi
Frontal sinus fractures, particularly anterior sinus fractures, are relatively common facial fractures. Many agree on the general principles of frontal fracture management; however, the optimal methods of reduction are controversial. The subbrow approach enables accurate reduction and internal fixation of the fractures in the anterior table of the frontal sinus by allowing direct visualization of the fracture. Given the surgical success in reduction and rigid fixation, patient satisfaction, and aesthetic benefits, the transcutaneous approach through a subbrow incision is superior to other reduction techniques used in the management of an anterior table frontal sinus fracture...

Dermatofibrosarcoma protuberans is a soft tissue sarcoma that is dermal in origin. The incidence is <0.1% of all malignancies and 1% of soft tissue sarcoma. Most commonly, it involves trunk (62%) followed by extremities (25%) and head and neck (13%). It is a slow growing tumor with locally aggressive behavior. Here, a 50-year-old female diagnosed with orbital dermatofibrosarcoma developed extra-axial component in right frontal region even on chemotherapy. Hence, the bad prognostic factors are yet to be established in dermatofibrosarcoma protuberans...

A 33-year-old female intact orange-winged Amazon parrot (Amazona amazonica) presented for a slowly growing mass over the right eye. A computed tomography scan performed with and without intravenous contrast revealed a heterogeneous mixed soft tissue and mineral-dense mass with a small area of non-contrast-enhancing fluid density located between the orbits at the caudal aspect of the nasal passages, with associated lysis of the right caudal nasal passage and the right frontal bone. Following euthanasia, the mass was found to consist of soft tissue between the right eye and nostril over the right frontal bone...

BACKGROUND: Iatrogenic injury to the trochlea is a potential complication of the Draf III or endoscopic modified Lothrop procedure; however, the location of the trochlea from within the sinus cavity has yet to be clearly characterized. We performed the first cadaveric study assessing the position of the trochlea in relation to the first olfactory neuron, a commonly identified landmark during the Draf III procedure. METHODS: Thirteen external dissections of the trochlea were performed on 7 disarticulated cadaveric heads via an extended Lynch type incision...

OBJECTIVE In the present study the authors aimed to determine preferred locations of meningiomas by avoiding descriptive analysis and instead using voxel-based lesion mapping and 3D image-rendering techniques. METHODS Magnetic resonance images obtained in 248 treatment-naïve meningioma patients with 260 lesions were retrospectively and consecutively collected. All images were registered to a 1-mm isotropic, high-resolution, T1-weighted brain atlas provided by the Montreal Neurological Institute (the MNI152), and a lesion frequency map was created, followed by 3D volume rendering to visualize the preferred locations of meningiomas in 3D...

BACKGROUND: The Draf III approach to the frontal sinus can be used during revision endoscopic sinus surgery for chronic rhinosinusitis and to provide access for tumor resection, mucoceles, and repair of cerebrospinal fluid leaks. OBJECTIVE: To describe a simple and safe way to perform a Draf III approach by using the "outside-in" approach. METHODS: By using a 0° endoscope and a single 15°, 5-mm, coarse diamond burr, the main steps of the procedure are the following: (1) elevation of the mucosal flaps and creation of the septal window, (2) drilling out the frontal beak, (3) creation of neo-ostium and removal of the interfrontal septum, (4) joining the neo-ostium with the frontal recesses, (5) smoothing off the cavity and lowering of the "frontal T," and (6) use of mucosal flaps and grafts to cover exposed bone...

INTRODUCTION: Sinonasal squamous cell carcinoma (SCC) accounts for <1% of all malignancies but represents 70% of sinonasal cancer. Up to 10% of SCCs are associated with inverted papilloma (IPSCC). Studies that compare patients, treatment, and outcomes of SCC and IPSCC are absent in the literature. METHODS: A retrospective review of patients with SCC and those with IPSCC at Cleveland Clinic and Indiana University from 1995 to 2015. The records were analyzed for demographics, tumor characteristics, treatment, and outcomes...

BACKGROUND: Use of absorbable packing materials after functional endoscopic sinus surgery (FESS) is associated with increased patient comfort and a lack of need for packing removal. Different materials may induce different patterns of mucosal healing and hemostasis. This study investigated the effect of fibrin sealant (FS; Tisseel) or biodegradable synthetic polyurethane foam (Nasopore(®) ) packing on hemostasis and wound healing after FESS. METHODS: This prospective randomized controlled trial included 35 consecutive patients who underwent bilateral FESS for chronic rhinosinusitis...

BACKGROUND: The role of human papillomavirus (HPV) in sinonasal squamous cell carcinoma (SNSCC) is not well understood. METHODS: The National Cancer Database was queried for cases of SNSCC with known HPV status. Demographics, socioeconomic variables, TNM stage, histology, grade, treatment modalities, and overall survival (OS) through 5 years were compared between HPV-positive and HPV-negative tumors. Cox proportional hazard regression analyses were performed. RESULTS: Seven hundred seventy (770) cases were identified; 526 were HPV-negative (68...

Frontal sinus fractures account for 2% to 15% of maxillofacial injuries. Up to 66% to 87% of the patients with frontal sinus fractures experience associated facial fractures. The majority of classifications used today categorize frontal sinus fractures depending on the integrity of the anterior table, posterior table, and the nasofrontal outflow. A retrospective study was performed, which included 24 patients diagnosed with frontal sinus fractures. Treatment in all patients consisted of open reduction and bone fixation...

We report two cases of cerebral venous thrombosis (CVT) which serial arterial spin labeling (ASL) was useful in evaluating the clinical course of the disease. A 48-year-old female presented with acute seizure, and was diagnosed as transverse-sigmoid sinus thrombosis. ASL imaging revealed low signal intensity in the right temporal lobe, suggesting the decreased perfusion by elevated venous pressure. Soon after the treatment, while the development of venous collateral has not fully observed by magnetic resonance (MR) angiography, low ASL signal within the right temporal lobe have shown remarkable improvement...

RATIONALE: Intradiploic meningiomas are a subset of extradural meningiomas that arise in the skull. They are mostly localized in the frontoparietal and orbital regions, and they are often mistaken for primary bone tumors. PATIENT CONCERNS: The patient was a 48-year-old man with headache and a 12-year history of frontal cranium occupation, which was first discovered in 2005 and enlarged in 2009. The patient had a history of fracture in his frontal cranium 12 years ago...

BACKGROUND: With their Pan-American distribution, long-nosed armadillos (genus Dasypus) constitute an understudied model for Neotropical biogeography. This genus currently comprises seven recognized species, the nine-banded armadillo (D. novemcinctus) having the widest distribution ranging from Northern Argentina to the South-Eastern US. With their broad diversity of habitats, nine-banded armadillos provide a useful model to explore the effects of climatic and biogeographic events on morphological diversity at a continental scale...
