Anatomy of the Ear01:16

Anatomy of the Ear

9.9K
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...

Pleiotropy01:33

Pleiotropy

42.0K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

The Auditory Ossicles01:11

The Auditory Ossicles

2.5K
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...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias01:25

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

249
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

148
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Congenital Malformations

Background:

  • Polyotia is a rare auricular malformation with ambiguous definitions and no standardized surgical treatment.
  • Previous diagnostic criteria for polyotia have been inconsistent, leading to challenges in management.

Purpose of the Study:

  • To establish objective diagnostic criteria for polyotia.
  • To introduce a refined surgical technique for polyotia reconstruction.

Main Methods:

  • Retrospective analysis of 34 cases diagnosed and treated for polyotia between January 2016 and March 2019.
  • Review of preoperative photographs, clinical manifestations, and surgical records.

Main Results:

  • New criteria diagnosed 12 cases as polyotia and 22 as accessory tragus.
  • Polyotia redefined as a broad-based accessory auricle with an accessory cavitas conchae.
  • Surgical design focused on cartilage and skin grafts for reconstruction.

Conclusions:

  • Objective criteria for polyotia diagnosis include an accessory auricle and accessory cavitas conchae.
  • Surgical reconstruction emphasizes filling concavities and rebuilding the tragus using cartilage and skin.
