Anterior external bony ear canal bulge
1Department of Otolaryngology, Faculty of Medicine (UMMC), University Malaya, Kualalumpur, Malaysia.
Summary
Anterior external ear canal wall bulge is common in Malaysia, affecting about one-third of the population across different ethnic groups. This study investigated its prevalence in Malays, Chinese, and Indian individuals.
Area of Science:
- Otolaryngology
- Anatomy
- Public Health
Background:
- The anterior external bony ear canal bulge is a anatomical variation.
- Understanding its prevalence is important for otologic assessments.
Purpose of the Study:
- To determine the prevalence of the anterior external bony ear canal bulge.
- To assess variations in prevalence among different ethnic groups in Malaysia.
Main Methods:
- A study involving 100 patients of each sex from three major ethnic groups in Malaysia.
- Examination using otoscope and microscope for accurate visualization.
Main Results:
- The anterior external ear canal wall bulge was observed in 34% of Malays.
- Prevalence was 32% in Chinese and 29.5% in Indian participants.
- Overall, approximately one-third of the Malaysian population studied exhibited this bulge.
Conclusions:
- The anterior canal wall bulge is a common finding in the Malaysian population.
- Prevalence appears relatively consistent across the studied ethnic groups.
- Findings contribute to baseline data for otologic evaluations in the region.

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...
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...

01:14Cranial 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,...

01:15Auditory Pathway
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking the...

01:24Nose and Nasal Cavity
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
