Summary
Hearing impairment and balance issues are often non-cancerous. However, tumors in the ear canal, middle, or inner ear can cause these symptoms, requiring treatments like surgery and chemotherapy.
Area of Science:
- Otolaryngology
- Oncology
- Pathology
Background:
- Common ear symptoms like hearing loss, tinnitus, and balance disturbance are typically due to non-neoplastic conditions such as otitis media, otosclerosis, or trauma.
- Less frequently, these auricular signs and symptoms arise from neoplastic space-occupying lesions.
Purpose of the Study:
- To review the types and origins of neoplastic diseases affecting the auricular apparatus.
- To outline the common treatment modalities for malignant auricular diseases.
Main Methods:
- Literature review of neoplastic diseases affecting the external, middle, and inner ear.
- Analysis of the incidence and age distribution of various auricular malignancies.
- Summary of standard treatment protocols for auricular cancers.
Main Results:
- The external ear can develop squamous cell carcinomas and basal cell carcinomas.
- The middle and inner ear may harbor metastatic deposits, primary squamous cell carcinomas, and adenocarcinomas.
- Most auricular malignant diseases affect adults, with rhabdomyosarcomas of the middle ear being an exception occurring in children.
Conclusions:
- Malignant diseases of the auricular apparatus, though less common than non-neoplastic causes, necessitate comprehensive treatment strategies.
- Treatment typically involves a multimodal approach combining surgery (often including radical temporal bone excision), radiotherapy, and chemotherapy.

01:31Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
01:13The 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.
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial 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...

01:11The 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...

01:16Anatomy 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...
