Larynx

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...

Pharynx

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...

Anatomy of Respiratory System I: Upper Respiratory Tract

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.

Respiratory System Abnormal Finding II: Palpation and Auscultation

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:

The Hyoid Bone

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Physical Assessment of the Respiratory Tract IV: Auscultation

Physical Assessment of the Respiratory Tract IV: Auscultation

Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Summary

Phantom larynx sensation is a newly described phenomenon following total laryngectomy. This study found 69% of patients reported phantom sensations or responded to stimulation, suggesting a real post-surgical experience.

Otolaryngology
Neurology
Surgical Outcomes

Background:

Phantom limb phenomenon is well-documented after limb amputation or deafferentation.
Phantom sensations following laryngectomy have not been previously described in medical literature.
Understanding post-surgical sensory experiences is crucial for patient care and rehabilitation.

Purpose of the Study:

To investigate the occurrence of a phantom larynx phenomenon in patients who have undergone total laryngectomy.
To determine if subjective sensations or physical responses to stimulation indicate a phantom larynx.
To establish if this phenomenon differs from control groups without laryngectomy.

Main Methods:

Retrospective clinical study involving 35 patients post-total laryngectomy and 57 controls.
Data collection included subjective reporting of phantom larynx sensations.
Phantom phenomenon was elicited via cutaneous stimulation of the neck and face.

Main Results:

A phantom larynx phenomenon was observed in 24 out of 35 (69%) post-total laryngectomy patients.
These patients reported subjective sensations or showed positive responses to cutaneous stimulation.
No phantom phenomenon responses were noted in the control group.

Conclusions:

The study concludes that a phantom phenomenon does occur after total laryngectomy.
This suggests a neurological or sensory alteration specific to the laryngeal removal.
Further research is warranted to explore the mechanisms and implications of phantom larynx.
