Editing Inner ear (section)

=== Blood supply ===
The bony labyrinth receives its blood supply from three arteries:
1 – Anterior tympanic branch (from maxillary artery).
2 – Petrosal branch (from middle meningeal artery).
3 – Stylomastoid branch (from posterior auricular artery).
The [[membranous labyrinth]] is supplied by the [[labyrinthine artery]].
Venous drainage of the inner ear is through the labyrinthine vein, which empties into the [[sigmoid sinus]] or [[inferior petrosal sinus]].
