OSTEOMA OF THE FRONTAL SINUS [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1918
The occurrence of osteoma of the frontal sinus is relatively infrequent, as may be judged from the fact that Sewall, 1 after carefully reviewing the literature, found only ninety-two cases. In these cases the diagnosis was based on the presence of anatomic deformities secondary to the osteoma; in only a few had the roentgen ray been used to confirm the

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

open access: yesThe Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

A cautionary tale of hydroxyapatite cement use in frontal sinus obliteration

open access: yesInterdisciplinary Neurosurgery, 2020
Cerebrospinal fluid leak is a major complication of parasellar surgery and may be repaired using an extradural endoscopic approach involving extensive debridement of the sinus mucosa.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

An isolated intracranial mucocoele herniated from the frontal sinus

open access: yesB-ENT, 2015
An isolated intracranial mucocoele herniated from the frontal sinus. Mucocoeles are chronic mucosa-lined retention cysts that occur due to sinus ostium obstruction and expand along the path of least resistance, most commonly involving the frontal sinus ...

External approach to frontal sinus mucocele: A forgotten technique?

open access: yesRevista Portuguesa Otorrinolaringologia e Cirurgia de Cabeça e Pescoço, 2020
Frontal sinus mucoceles are benign, slow growing lesions capable of local bone erosion. Currently, endoscopic sinus surgery is the mainstay for its treatment, however there are still indications for an external surgical approach.

Paranasal recesses and rostral airspace volume covary with echolocation call frequency in emballonurid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The mammalian rostrum has multiple functions including serving as the upper jaw, supporting olfactory sensory structures, conditioning inspired air, and—for some mammals—transmitting sound. Several groups of bats independently evolved bony inflations on the dorsolateral surfaces of their rostra.
