The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

The Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

External Acoustic Meatus Approach for Ultrasonographic Evaluation of the Temporomandibular Joint: An Anatomical Validation and Proof‐of‐Concept Study

Clinical Anatomy, EarlyView.
ABSTRACT Temporomandibular disorders (TMD) represent a public health problem, affecting 31% of adults and the elderly and 11% of children and adolescents. Interest is growing in using ultrasound to evaluate the temporomandibular joint (TMJ). However, researchers need to standardize a reliable method.

Presence of Emissary Veins in the Glabellar Region in Metopic Craniosynostosis

Clinical Anatomy, EarlyView.
ABSTRACT Emissary veins connect intra‐ and extracranial venous circulation by bridging the dural venous sinuses to the external veins of the skull. Their variable presence and location may have important implications in perioperative blood loss. Clinical observations and previous studies suggest that emissary veins are more frequently present in the ...

Calcium sulfate matrix as local antibiotic carrier in the mastoid

Clinical Case Reports, 2022
We describe the use of calcium sulfate beads as antibiotic carrier in a patient, who suffered from chronic mastoiditis with consecutive otogenic meningitis due to Burkholderia cenocepacia. Our findings suggest a possible role of calcium sulfate matrix as
