Metastasis of prostate adenocarcinoma to the frontal and ethmoid sinus

open access: yesUrology Research and Practice, 2019
Intracranial metastasis of prostate cancer is rarely seen, and there are few studies in this regard in the literature. Most of these studies in the literature comprise the metastasis of prostate cancer to the sphenoid sinus, and metastasis to the frontal

Inflammatory Signatures Beyond Th1/Th2 Endotypes Provide Insights Into Postoperative Recurrence in Chronic Rhinosinusitis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) represents a spectrum of inflammatory endotypes, driven by distinct T helper (Th) immune responses. The high rate of recurrent disease despite appropriate medical and surgical interventions highlights the need for improved characterization beyond the traditional type 2 and non‐type 2 phenotypes to better

Early Versus Late Recurrence in Olfactory Neuroblastoma: A Multi‐Institutional Analysis of Predictive Risk Factors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory neuroblastoma (ONB) exhibits variable recurrence patterns, with significant late recurrences occurring years after treatment. We investigated cutoff periods to define late recurrence and identified predictors that distinguish patients at risk of late recurrence from those considered cured.

Sex identification based on paranasal sinuses measurements using multislice computed tomography in a sample of adult Egyptians

open access: yesEgyptian Journal of Forensic Sciences
Background Identification is a major challenge in forensic science. Paranasal sinuses show individual and sex-related variations. The complexity of the internal architecture of the ethmoid sinus, its deep anatomical location, and relative protection from

Transorbital Endoscopic Identification of Supernumerary Ethmoid Arteries

open access: yesAllergy & Rhinology, 2016
Background Anterior and posterior ethmoid arteries supply the paranasal sinuses, septum, and lateral nasal wall. Precise identification of these arteries is important during anterior skull base procedures, endoscopic sinus surgery, and ligation of ...

Early Endoscopic Repair of Traumatic Skull Base Dural Injuries: Challenging the Dogma of Conservative Management

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Traditional management of traumatic skull base dural injury has often favored observation and conservative therapy, despite the risk of delayed intracranial complications. This paradigm originated when operative intervention required craniotomy and carried significant morbidity.

Primary chordoma of the ethmoid sinus [PDF]

open access: yesThe Journal of Laryngology & Otology, 2000
Primary chordoma of the paranasal sinuses are extremely rare tumours, with only a small number of cases verified and published in the literature. It appears that only five of these cases involved the ethmoid sinuses either as a primary or by local invasion, and of these documented cases only one other has been found to solely involve the ethmoid sinus.
