Quelques microfacies neogenes nord-aquitains

Bulletin de la Société Géologique de France, 1967
Abstract The Aquitanian and Burdigalian deposits outcropping in Villandraut and Saucats have similar microfacies, and the depositional environments of the two series appear to have been relatively uniform as evidenced by the structure of the limestone matrix.

Endoscopic‐Assisted Cochlear Implantation via a “Microfacial Recess”

The Laryngoscope
Syndromic patients can have severely anomalous anatomy significantly challenging conventional cochlear implant (CI) surgery. This case report describes a 20‐year‐old with brachio‐oto‐renal syndrome with a severely anomalous facial nerve completely covering the round window and preventing a traditional posterior tympanotomy CI.
