Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Pharynx01:20

Pharynx

The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
Respiratory System Abnormal Finding II: Palpation and Auscultation01:31

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
Trachea01:22

Trachea

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...

Summary

Foreign body inhalation, especially fish bones in the larynx, is a critical emergency. Prompt diagnosis and intervention are vital to prevent severe respiratory distress and potential disaster.

Area of Science:

  • Otolaryngology
  • Emergency Medicine
  • Medical Case Reports

Background:

  • Foreign body aspiration is a significant medical event.
  • Laryngeal impaction is rare but poses an immediate respiratory threat.
  • Timely diagnosis is crucial to avert critical outcomes.

Purpose of the Study:

  • To present two cases of fish bone impaction in the larynx.
  • To discuss the diagnostic and management challenges of laryngeal foreign bodies.
  • To review the existing literature on laryngeal foreign body ingestion.

Main Methods:

  • Case report presentation.
  • Review of relevant medical literature.
  • Analysis of foreign body disposition within the larynx.

Main Results:

  • Two distinct cases of fish bone lodged in the larynx were identified.
  • One bone was lodged in an anteroposterior orientation, the other in a coronal disposition.
  • The cases highlight the varied presentations and locations of laryngeal foreign bodies.

Conclusions:

  • Fish bone impaction in the larynx, though uncommon, necessitates urgent medical attention.
  • Varied orientations of impacted foreign bodies can complicate diagnosis and removal.
  • Awareness and prompt recognition are key to managing laryngeal foreign body emergencies.
