Septic cavernous sinus thrombosis (SCST) is an uncommon consequence of head and face infection, but a rare complication after craniofacial fracture. In this case, SCST developed in a 13-year-old girl following a minor fall during volleyball, with impact and resulting abrasive contusion of the left forehead. She developed watery rhinorrhea, progressive headache, fever, nausea, vomiting, and left proptosis with blurred vision, and was admitted to hospital 3 days after injury. Drowsiness, high-grade fever, severe headache, left ocular pain with marked periorbital swelling, and paralysis of extraocular eye movements developed...

A 48-year-old man presented to urgent care with recurrent epistaxis over 6 months. Initially, nosebleeds were controlled with packing or cautery. Ultimately, he was referred to ear, nose and throat department and underwent nasal endoscopy which revealed polypoid tissue. A biopsy of the polyp showed non-specific inflammation with no evidence of malignancy. Follow-up maxillofacial CT revealed a large mass lesion in the right maxillary sinus, right nasal fossa, much of the ethmoids and right sphenoid, with destruction of adjacent bony structures...

BACKGROUND: Chronic sphenoid sinusitis refractory to both medical therapy and sphenoidotomy requires a more extended intervention based on the principles of salvage surgery. Our aim is to describe the sphenoid drill out technique as a sphenoid salvage intervention and to outline its implications on clinical outcome and quality of life. METHODOLOGY: 12 patients with chronic sphenoiditis undergoing a sphenoid drill out procedure were examined by nasal endoscopy preoperatively and postoperatively for one year...

CONTEXT: Bilateral inferior petrosal sinus sampling (BIPSS) using hCRH is currently considered the 'gold standard' test for the differential diagnosis of ACTH-dependent Cushing's syndrome (CS). Vasopressin is more potent than CRH to stimulate ACTH secretion as shown in animal studies, however; no comparative data of its use is available during BIPSS. OBJECTIVE: To study the diagnostic accuracy and comparison of hCRH and lysine vasopressin (LVP) stimulation during BIPSS...

Analysis of ions in sphenoidal fluid can be a useful index for the diagnosis of drowning. We evaluated the reference ranges of non-drowning cases using statistical methods and three indices: sodium ion (Na+), summation of sodium and potassium ions (SUMNa+K), and summation of sodium, potassium and chloride ions (SUMNa+K+Cl). The reference ranges were 96≤Na+<152, 139≤SUMNa+K<179, 243≤SUMNa+K+Cl<311(mEq/L), respectively. Victim indices outside of the reference ranges indicate that the victim probably inspired water with higher or lower ion concentrations than those of body fluid in sphenoidal sinuses...

BACKGROUND: Reconstruction of large anterior skull base (ASB) defects after an endoscopic endonasal transcribriform approach (EEA-TC) remains a challenge despite the advent of the vascularized pedicled nasoseptal flap (PNSF). OBJECTIVE: We describe a relaxing PNSF slit incision that extends the anterior and posterior reach of the PNSF to maximize tensionless flap coverage of transcribriform ASB defects. METHODS: A retrospective chart review was conducted on 20 consecutive patients who underwent EEA-TC and subsequent PNSF reconstruction with a relaxing slit incision...

The objective of the present study was to determine the biological age of the unrecognized individuals based on the analysis of CT-scanograms of the skull and the craniovertebral region in the sagittal projection. We investigated the structure of the spongy substance of the clinoid plate of the sella turcica and the clivus of the cranium, involution of the vertebrae configuration in the medial atlantoaxial articulation, frontal and sphenoidal sinuses. A total of 80 skulls of Caucasoid individuals at the age ranging from 4 to 84 years belonging to an Eastern Slavonic population (free from the pathological lesions in the above cranial structures) were available for the examination...

BACKGROUND: The aims of this study were to analyze the relationships between the medial orbitofrontal artery (MOFA) and the anterior skull base (ASB) including anatomical endonasal landmarks using computed tomography angiography (CTA). METHODS: We studied 52 CTAs using OsiriX software. All CTAs were placed in the same anatomical position. MOFA was identified in the sagittal and coronal plane and its correlation with ASB was analyzed. The distance between the MOFA and landmarks for endonasal surgery were obtained, determining the high risk areas for its injury...

OBJECTIVE Multiple approaches have been designed to reach the medial middle fossa (for lesions in Meckel's cave, in particular), but an anterior approach through the greater wing of the sphenoid (transalisphenoid) has not been explored. In this study, the authors sought to assess the feasibility of and define the anatomical landmarks for an endoscopic anterior transmaxillary transalisphenoid (EATT) approach to Meckel's cave and the middle cranial fossa. METHODS Endoscopic dissection was performed on 5 cadaver heads injected intravascularly with colored silicone bilaterally to develop the approach and define surgical landmarks...
