Endoscopic Cholesteatoma Surgery
Published on: January 19, 2022
Summary
Petrous bone cholesteatomas are rare and challenging surgical cases. This study presents a classification and surgical strategy for managing these complex tumors.
Area of Science:
- Neurosurgery
- Otolaryngology
- Skull Base Surgery
Background:
- Petrous bone cholesteatoma is a rare pathology.
- Surgical management presents significant challenges due to proximity to critical structures.
Purpose of the Study:
- To present a personal classification of petrous bone cholesteatomas.
- To review surgical attitudes and outline a surgical strategy.
- To detail management of five specific cases.
Main Methods:
- Review of 54 surgical operations between 1978 and 1990.
- Classification based on tumor location and extent.
- Application of specific surgical approaches: radical petromastoid exenteration, middle cranial fossa approach, and enlarged transcochlear approach.
Main Results:
- Specific approaches were tailored to tumor size and location.
- Radical petromastoid exenteration and middle cranial fossa approach for smaller cholesteatomas.
- Enlarged transcochlear approach for extensive infralabyrinthine and apical cholesteatomas.
Conclusions:
- A tailored surgical strategy is crucial for successful petrous bone cholesteatoma management.
- Different surgical approaches offer effective solutions based on cholesteatoma characteristics.
- Detailed case presentations highlight clinical presentation and management outcomes.

Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Anatomy of the Ear
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
The Auditory Ossicles
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
