About This File

This file is a micro segmentation of bony labyrinth taken from a CT scan. I paid particular attention to the vestibule bone with its 2 windows, the cochlea and the semicircular canals. To exhibit all bony labyrinth I eliminated the middle ear structures, but I kept the hammer, the incus and the facial nerve canal. you can observe the course of the facial nerve canal in its three portions with two knees and with his natural dehiscences.
I also left in place the internal auditory canal and the internal auditory meatus where are visible the facial cochlear and vestibular nerves openings with the bony eminences that separate them (Bill's Bar, Crista falciformis).
You can open the file with any program for managing files .stl and navigate in three dimensions between or within the bony structures (I do with the program called Preview in Mac) to facilitate the study of these complex structures. I added screenshots which shows the most important structures.
The file is already ready to be printed and does not need cleaning.
The dimensions are X: 21.3 mm, Y: 16.4 mm, Z: 16.4 mm (2x1.6x1.6 cm).
You can easily increase the size if you want to print a solid model of the inner ear

 

P.S. I spent many hours to this work and would like to have your opinions and suggestions on where to improve. I provide for those who want the file at different stages of processing

I was really impressed with the amount of detail that has gone into this model.
As someone who has just started researching the structure of the inner ear; the combination of this model and "Temporal Bone Left"has given me a greater appreciation for where everything is in relation to each other.
My only concern about the model was that the stirrup wasn't present. However it is understandable as it is quite a small bone.

Disclaimer: I used this model for creating an image rather than 3D printing.

      This is a .stl file of a left temporal bone ready for 3d printing.
       
      I have segmented a CT scan paying attention to all the important bony structures of the ear.
      In the .stl screenshots you can see the mastoid, malleus, incus, the bony canal of the facial nerve, the stylomastoid foramen Etc.
      I do this for my training and the idea is to perform a mastoidectomy just in my desktop
      i have printed my personal 3d plaster model (you can see in the screenshots) but i haven't the courage to destroy it whit the drill.....
       
      I hope that my work can be of help to anyone who wants to try to drill a faithful model of temporal bone at home or simply want to study the anatomy in a versatile 3d .stl Model
       
      Good Job
