Frontal sinus

D A Gol'bin, V A Cherekaev
The article presents the literature data on the structural variability and age-related features of the midline anatomical structures of the anterior skull base (frontal sinus, ethmoid bone, anterior parasellar region, and medial orbital wall). This is the area of surgical interests of neurosurgeons and rhinosurgeons. The study objective is to analyze the literature data on the individual variability and age-related anatomy of these structures. The work is illustrated with original images from the authors' personal archive...

Intracranial abscess is one of the most serious complications of frontal sinusitis, particularly among adolescents, even in the absence of odontogenic infection. Polymicrobial infections due to anaerobes are common. Because antibiotic therapy alone is usually ineffective, early endoscopic sinus surgery is the key for infection control and good clinical outcomes.

Endoscopic endonasal approaches (EEA) have gained popularity and acceptance in skull base surgery over the last two decades. So-called expanded EEA allow access in the sagittal plane from the frontal sinus to the odontoid process. The endoscopic endonasal transclival approach allows a unique trajectory into the midline clivus and skull base that is unachievable from traditional craniotomy approaches to lesions such as chondrosarcomas, chordomas, and posterior fossa meningiomas. In this review, we will assess the benefits and drawbacks to using an endoscopic endonasal approach versus transcranial approach to these challenging lesions, assess the anatomical limits of endoscopic endonasal transclival surgery, and discuss the published literature on the topic...

The frontal sinus, due to its unique anatomical features, has become an important element in research for individual identification. Previous studies have demonstrated the use of frontal sinus as an indicator for sex discrimination; however, the sex discrimination rate using frontal sinus was lower compared to that using the traditional morphological methods. In order to improve the sex discrimination percentage, we developed a new method involving the measurement of the frontal sinus index and frontal sinus area from lateral cephalogram radiographs...

BACKGROUND: Nasal irrigations with antibiotics are used to eradicate Pseudomonas aeruginosa from the upper airways in patients with cystic fibrosis (CF) and thereby avoid lung colonisations; nevertheless, the efficacy is uncertain. METHODOLOGY: The aim of this study was to investigate the accessibility and durability of solutions in the sinuses before and after sinus surgery. The participants irrigated their noses with radioactively marked saline and were evaluated using a dynamic SPECT/CT scan...

The archaeological excavations carried out in 1999 in the Collatina necropolis of the Roman Imperial Age (1st-3rd centuries AD) (Rome, Italy) discovered the skeletal remains of two adult males with evidence of paranasal lesions. Both individuals showed postmortem damage in the frontal bone, through which it was possible to macroscopically detect an oblong new bone formation. In both specimens, radiological examination of the defects' morphology showed new pediculated-based bone formations. Radiology also confirmed the presence of benign osseous masses arising from the right frontal sinus and interpreted as osteomata...

A 69-year-old woman with a previous history of migraine without aura developed throbbing headache in the right frontal region accompanied by nausea, lasting more than 4 hours a day. The headache intensity was more severe than that of usual her migraine headaches. Administration of eletriptan in the previous hospital improved her headaches. However, one month later the patient experienced more intense headaches in the same region and then was referred to our hospital. MR angiography showed abnormal signal intensities in the cavernous sinus...

Mucocele is benign, slow-growing, mucous-filled cystic lesions that arise in the paranasal sinuses. It causes progressive distension of the bony walls and induces compressive symptoms. Surgical treatment of paranasal sinus mucoceles includes endoscopic approach or external approach. The authors report a patient of frontal mucocele who presented with a history of progressive unilateral protrusion. Computed tomography scan revealed a large mucocele of the frontal sinus with orbital extension on the same side...

Endoscopic or transfacial external frontal sinus approaches do not provide good monitoring of the frontal sinus lateral extent. Moreover, endoscopic or transfacial external approaches remain associated with numerous complications or therapeutic failure, e.g. frontal sinus drainage pathway synechia, healing problems or residual hypoesthesia. We propose a rapid, easy-to-perform, 5-step procedure called the transpalpebral approach which is indicated in case of sequestered disease within the lateral extent of the frontal sinus...

Sinonasal mass is the abnormal growth of tissue from nasal cavity and mucosa of the paranasal sinuses. The growth may be benign or malignant. The benign lesion grows slowly and does not metastasize. The malignant lesion grows rapidly and metastasizes early. The aim of this study is to evaluate and diagnose the various types of sinonasal masses with MRI and its correlation with histopathological findings. This cross sectional descriptive study was carried out for a period of 02 years, from July 2015 to June 2017...

BACKGROUND: The International Frontal Sinus Anatomy Classification (IFAC) is an international consensus document published in 2016 to standardize the nomenclature of cells in the region of the frontal recess and frontal sinus. The IFAC was designed to be surgically relevant and anatomically precise. The current study was undertaken to assess the prevalence of the frontal cell variants as defined by the IFAC, as well as to determine the interrater reliability of the IFAC. METHODS: Three independent reviewers examined triplanar nondiseased maxillofacial computed tomography (CT) scans to assess the anatomy of the frontal recess according to the IFAC system...

The sinus pericranii refers to a set of clinical presentations that share a pathological communication between the scalp veins and the underlying cranial venous sinus. The nature of this connection ranges from the simple dilatation of the emissary veins, to wide connections through a calvarial bone loss leaving almost the cranial venous sinus in direct contact with the subcutaneous tissue. The authors present the case of an occipital pericranii sinus of intraoperative discovery. Congenital, post-traumatic or spontaneous, this anomaly is most often frontal and located on or close to the midline...

Frontal sinus osteoma accompanied by intracranial mucocele and local hyperostosis frontalis interna has never been reported. A 47-year-old woman presented with a 3-month history of intermittent headache. Physical examination revealed no neurological abnormality. Contrasted MRI showed a frontal heterogeneously enhanced lesion with adjacent non-enhanced cyst. Computed tomography showed a bone-density mass, which was accompanied by local hyperostosis frontalis interna, filled the left frontal sinus and extended intracranially...

Paranasal sinuses are highly variable among living and fossil hominins and their function(s) are poorly understood. It has been argued they serve no particular function and are biological 'spandrels' arising as a structural consequence of changes in associated bones and/or soft tissue structures. In contrast, others have suggested that sinuses have one or more functions, in olfaction, respiration, thermoregulation, nitric oxide production, voice resonance, reduction of skull weight, and craniofacial biomechanics...
