PURPOSE: Pneumosinus dilatans (PD) is a rare pathologic hyperaeration of the paranasal sinuses that causes serious deformation of the overlying bone and soft tissue. The condition occurs most commonly in the frontal sinus of young men who present with different complaints, including cosmetic. More than 100 cases have been reported in the literature since it was first described in 1898; however, the etiology of this condition remains unclear. MATERIALS AND METHODS: A systematic review of all available clinical publications on the subject of PD was conducted in the PubMed electronic database...

BACKGROUND: The balloon catheter has been used for a decade to dilate paranasal sinus outflow tracts. The question is: how wide and how durable is the dilation of drainage pathways in patients in long-term observations after this procedure? OBJECTIVE: The objective of our study was to observe the changes occurring in the frontal sinus drainage pathway (FSDP) in patients with frontal sinusitis at least 6 months after surgery using balloon catheters in an isolated procedure...

A 58-year-old man presented with slowly progressive chemosis, exophthalmos, and blepharedema of the left eye. Digital subtraction angiography revealed multiple dural arteriovenous fistulas(dAVFs)involving the bilateral tentorium, superior sagittal sinus, and right frontal convexity. In addition, occlusion of the left cavernous sinus and left sigmoid sinus were observed, which could lead to venous hypertension and might be associated with the occurrence of multiple dAVFs. Along with the congestion of the left ophthalmic vein, increased intracranial pressure due to the left tentorial dAVF with cortical venous reflux could have caused the left eye symptoms; therefore, the tentorial lesion was treated first...

OBJECTIVE: Delayed post-traumatic mucoceles are rare. We describe the surgical treatment of a post-traumatic ethmoidal mucocele with intra-orbital extension. METHOD: A uninostril endoscopic endonasal approach (EEA) was performed. The access was contralateral to the lesion to provide a wider lateral view. After a large sphenoid and ethmoid sinuses opening, the collection was drained and the optic nerve precociously identified. The orbital roof was eroded and the frontal dura mater directly visible...

Fungus ball (FB) is an non-invasive form of mycosis, that generally affects immunocompetent and non-atopic subjects. Involvement of the frontal sinus is extremely rare. We report two cases with frontal sinus fungus ball that underwent endoscopic endonasal frontal Draf type IIb or III sinusotomy with complete removal of the cheesy clay-like material. There were no intra-operative or postoperative complications, and no recurrence of disease was evident during the follow-up of 51 and 26 months, respectively. The Draf type IIb or type III frontal sinusotomy seems to be highly effective for the treatment of frontal sinus FB and can represent a valid alternative to the traditional external approaches...

Three third-instar Oestrus larvae were found in the frontal sinus of an adult female Asiatic ibex (Capra sibirica) in the Tian Shan mountain range, Kyrgyzstan. The larvae were identified as Oestrus ovis based on morphology and after sequencing and analyzing a fragment of the cytochrome oxidase I (COI) gene. In light of this identification and the fact that Asiatic ibex and livestock are sympatric in many areas in Central Asia, we discuss the risks of interspecific parasite spillover.

Background:Staphylococcus aureus biofilms contribute negatively to a number of chronic conditions, including chronic rhinosinusitis (CRS). With the inherent tolerance of biofilm-bound bacteria to antibiotics and the global problem of bacterial antibiotic resistance, the need to develop novel therapeutics is paramount. Phage therapy has previously shown promise in treating sinonasal S. aureus biofilms. Methods: This study investigates the long term (20 days) safety of topical sinonasal flushes with bacteriophage suspensions...

Paranasal sinus mucoceles are benign lesions that commonly present with orbital signs due to their anatomic proximity. We are reporting a case of bilateral frontal sinus mucocele presenting with spontaneous eyelid ecchymosis. To our knowledge this is the first case report of eyelid ecchymosis as the initial sign of this condition. In addition, our patient lacked commonly described symptoms such as diplopia or pain. This report highlights the importance of including frontal sinus mucocele in the differential diagnosis of spontaneous periorbital ecchymosis...

Although the medial femoral condyle has been used for reconstruction in various areas of the body, to the authors' knowledge it has not been used for frontal sinus reconstruction. The authors describe a novel approach to a complex patient using the medial femoral condyle cortiocoperiosteal free flap to reconstruct an anterior frontal sinus defect in conjunction with a recalcitrant mucocele.

One of the most challenging adaptations within the therians has been to ensure dynamic stability of the trunk during rapid locomotion in highly structured environments. A reorganization of limb mechanics and development of new sensors has taken place within their stem lineage. Rats, which have a similar lifestyle to the first therians, possess sinus hairs specialized for tactile sensing. It is supposed that carpal sinus hairs have a role in sensing substrate properties and can thus induce adjustments in limb kinematics and body posture according to the different surface diameters and structures detected...

Treatment of frontal sinus fractures depends on the structures involved: the anterior wall, the posterior wall and the nasofrontal duct. It may vary from the correction of the defect in the anterior wall to the cranialization with obliteration of the nasofrontal duct. The inversion of the frontal sinus's anterior wall to correct the defect in the fractured region is a good treatment option for sequelae, since this technique eliminates or reduces the use of biomaterial in the area, and allows direct assessment of the permeability of the nasofrontal duct...

We describe a case of a man aged 41 years who presented with a history of generalised headaches for 1 week and an acute episode of tonic-clonic seizures. He had no history of medical illness, was non-smoker, with an extensive family history of haematological disorders. Initial CT brain with contrast did not show any abnormalities in brain parenchyma. X-ray and CT right shoulder showed shoulder dislocation secondary to trauma associated with seizure prior to hospital admission. Subsequently, MRA and MRV brain was arranged, which revealed extensive expansible occlusive filling defect dominating the middle of superior sagittal sinus with left frontal cortical and subcortical acute oedema...

BACKGROUND: The trans-frontal-sinus-subcranial approach (TFSSA) allows for direct exposure and removal of olfactory groove meningiomas (OGMs), without any brain retraction. Compared to other skull base approaches (like fronto-orbito-basal, transbasal, subcranial, fronto-orbito-zygomatic and one-and-half approach), it could offer the same advantages but it is less invasive. OBJECT: We report the results in a series of 21 consecutive patients harboring OGMs and operated through TFSSA, in order to propose a viable alternative approach...

Meningiomas originate in the central nervous system and are the most common intracranial benign tumor. However, although rarely, they can develop extracranially. Primary extracranial meningiomas are frequently misdiagnosed, resulting in inappropriate clinical management. The most common sites of extracranial meningiomas include the skull, scalp, orbit, nose, paranasal sinuses, middle ear, neck, and skin. A 77-year-old woman presented with a mass on her left eyebrow. Computed tomography revealed an enhancing soft tissue mass in the left frontal area...
