Summary
Tympanic membrane (TM) herniation into the ear canal is rare. This case report details a TM hernia likely caused by prolonged Valsalva maneuvers, successfully treated with endoscopic resection.
Area of Science:
- Otolaryngology
- Pathology
Background:
- Tympanic membrane (TM) bulging is common, but TM herniation into the external auditory canal (EAC) is exceptionally rare.
- This condition can cause symptoms like ear fullness, hearing loss, and otorrhea.
Observation:
- A 66-year-old male presented with left aural fullness, bilateral hearing loss, and otorrhea.
- Preoperative evaluation suggested a TM hernia in the left EAC.
- The patient exhibited higher-than-normal passive opening pressure and absent active opening of the Eustachian tube.
Findings:
- Endoscopic transcanal resection of the soft mass was performed.
- Histopathology confirmed the diagnosis of TM hernia.
- Ventilation tubes were inserted bilaterally.
Implications:
- This case highlights a rare cause of ear symptoms, potentially linked to chronic Valsalva maneuvers.
- Endoscopic surgery offers a viable transcanal approach for TM hernia resection.
- Understanding Eustachian tube dysfunction is crucial in managing TM herniation.

01:16Anatomy of the Ear
13.3K
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...

01:14Assessing Body Temperature - Tympanic membrane
1.3K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

01:11The Auditory Ossicles
3.6K
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...

01:22Esophageal Perforation-I: Introduction
726
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

01:28Tracheostomy: Procedure and Tubes
4.7K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

01:28Types of Membrane Protrusions
3.9K
The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These membrane protrusions are a result of cytoskeletal rearrangement. The most widely observed cell protrusions include lamellipodia, pseudopodia, filopodia, microvilli, invadopodia, and podosomes. These protrusions can be of two types — static or dynamic.
