Frontal sinus

Griffin D Santarelli, Joseph K Han
Propel and Propel Mini sinus implants are mometasone furoate-coated bioabsorbable stents used as an adjunct in the management of chronic rhinosinusitis after endoscopic sinus surgery. The original sinus implant was deployed in the ethmoid sinuses to provide medialization of the middle turbinate, decrease scarring and mucosal adhesions, limit polyp regrowth, and reduce mucosal inflammation. A structurally smaller version of the Propel, the Propel Mini, was developed and now has been approved for endoscopic placement in the frontal sinuses...

BACKGROUND: Endoscopic sinus surgery represents a cornerstone in the professional development of otorhinolaryngology trainees. Mastery of these surgical skills requires an understanding of paranasal sinus and skull-base anatomy. The frontal sinus is associated with a wide range of variation and complex anatomical configuration, and thus represents an important challenge for all trainees performing endoscopic sinus surgery. METHODS: Forty-five otorhinolaryngology trainees and 20 medical school students from 5 academic institutions were enrolled and randomized into 1 of 2 groups...

BACKGROUND: Intracranial abscess collections, though uncommon, are dreaded complications of head trauma, neurosurgical operations, meningitis, and otogenic, mastoid, and paranasal air sinus infections. Combining surgical evacuation with the appropriate antibiotic therapy is the effective treatment for intracranial abscesses. However, literature on surgical treatment is replete with several procedures which, on their own, may not. OBJECTIVES: To determine the epidemiology and outcomes (of various treatment modalities) of intracranial abscesses in our institution, a major referral center for neurosurgical conditions in the midwestern region of Nigeria...

INTRODUCTION: Various methods have been proposed to evaluate a patient's developmental status. However, most of them lacked precision and failed to give a reliable estimate of skeletal maturity. The aims of this study were to evaluate the association between frontal sinus morphology and cervical vertebral maturation for the assessment of skeletal maturity and to determine its validity in assessing the different stages of the adolescent growth spurt. METHODS: A cross-sectional study was performed on the pretreatment lateral cephalograms of 252 subjects aged 8 to 21 years...

INTRODUCTION: Cerebral venous sinus thrombosis (CVST) is a rare condition with the potential to cause severe morbidity and mortality. CVST can also occur after vestibular schwannoma (VS) surgery with the thrombosis of transverse and sigmoid sinus. However, there is not a single report of superior sagittal sinus (SSS) thrombosis after VS surgery reported in the literature. CASE REPORT: A 45-year-old lady presented to our centre with large left sided solid cystic VS...

Much of craniofacial trauma involves the frontal sinuses. Because of its response to injury, the frontal sinus mucosa has an innate ability to develop mucoceles, and if infected, mucopyocoeles. This article presents a therapeutic algorithm for all forms of craniofacial trauma with concentration on the most severe injury-the through and through fracture and its surgical remediation.

BACKGROUND: Chronic rhinosinusitis (CRS) is a multifactorial inflammatory airway disorder in which bacteria are implicated in the initiation and/or sustenance of disease in some patients. The sinuses are colonized by bacteria even in health, and the potential for sinus-specific niches harboring unique microbial consortia raises questions for clinical and research investigation. The objective was to determine the degree to which resident upper airways microbiota differ between individuals and anatomic sites, in order to determine the optimal site of microbial sampling for study in CRS...

Intracranial osteomas completely unrelated to osseous tissues are extremely rare. In the present study, the case of a 40-year-old female who presented with persistent headache is reported. Computed tomography (CT) and bone window CT revealed an ossified lesion in the frontal area. Fast imaging employing steady-state acquisition (FIESTA)/CT venography fusion imaging demonstrated that the mass was located just below the superior sagittal sinus and cortical veins, and had adhered partially to these veins. Surgery achieved complete tumor removal with preservation of the cortical veins and superior sagittal sinus...

Osteomas are the most common benign tumors of the paranasal sinuses. They are usually localized in the frontal sinus. Giant osteomas of the frontal sinuses are very rare but readily extend into the intraorbital or intracranial cavity, causing serious complications. This is a report of a 14 year-old boy with a bulging in frontal area and asymptomatic giant osteoma of the frontal sinuses. He had a history of minor trauma that had a bulging after 3 months. However, he referred to a plastic surgeon after 15 months...

Immunohistochemistry for protein gene product 9.5 (PGP 9.5), calcitonin gene-related peptide (CGRP) and the transient receptor potential cation channel subfamily V member 2 (TRPV2) was performed on human paranasal sinuses. It was found that in the paranasal sinuses, mucous membranes contain PGP 9.5-immunoreactive (PGP 9.5-IR) nerve fibers. Such nerve fibers terminated around large blood vessels as fine varicosities. Isolated PGP 9.5-IR nerve fibers were scattered beneath the epithelium. Glandular tissues were also innervated by PGP 9...

BACKGROUND: The nasoseptal flap (NSF) is commonly used to repair skull base defects via a transnasal endoscopic approach. The original description of the technique includes 2 parallel incisions that follow the sagittal plane of the septum. We describe a novel modification to the traditional NSF that allows coverage along the posterior wall of the frontal sinus. METHODS: In addition to the 2 sagittal incisions, a third incision is made between these coursing along the maxillary crest from the posterior edge to the midportion of the flap...
