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...

Mitral Regurgitation I: Introduction

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Sutures of the Skull

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

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:

Salivary Glands and Saliva

Salivary Glands and Saliva

The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

Cardiovascular System Abnormal Findings II: Auscultation

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Summary

Sulcus vocalis, a vocal fold groove, causes breathy and rough voice dysfunction. Diagnosis can be challenging, and treatments like phonosurgery often yield disappointing results, necessitating careful patient counseling.

Area of Science:

Otolaryngology
Speech Pathology
Vocal Fold Physiology

Background:

Sulcus vocalis is a groove on the vocal fold's free edge, impacting voice quality.
Classified into types I (superficial), IIa (vergeture), and IIb (pouch/cyst), it affects vocal fold mechanics.

Purpose of the Study:

To detail the characteristics and classification of sulcus vocalis.
To explain the resulting glottic dysfunction and diagnostic challenges.
To review current treatment options and their outcomes.

Main Methods:

Review of existing literature and clinical descriptions of sulcus vocalis.
Analysis of stroboscopic findings and diagnostic difficulties.
Discussion of etiological theories (acquired vs. congenital).

Main Results:

Sulcus vocalis leads to glottic dysfunction, characterized by breathiness (glottal leakage) and roughness (stiffness).
Diagnosis can be difficult, sometimes requiring general anesthesia.
Etiology is debated, with both acquired and congenital origins proposed.

Conclusions:

Phonosurgery and speech therapy are treatment options, but surgical outcomes can be disappointing.
Phonosurgery should be approached cautiously, with patients fully informed about potential outcomes, primarily voice loudness improvement.
