The hyoid bone: an overview

Area of Science:

• Anatomy
• Physiology
• Biomechanics

Background:

• The hyoid bone is a small, horseshoe-shaped bone situated between the mandible and the shoulder girdle.
• Classified as a sesamoid bone, it is unique due to its lack of direct articulation with other bones.
• Historically considered vestigial, the hyoid bone is integral to various physiological functions.

Purpose of the Study:

• To highlight the anatomical and physiological significance of the hyoid bone.
• To underscore the importance of hyoid bone knowledge in clinical practice.
• To emphasize the hyoid bone's role in essential functions like speech and respiration.

Main Methods:

• Review of anatomical and physiological literature.
• Analysis of the hyoid bone's structural connections.
• Examination of its functional roles in respiration, speech, and swallowing.

Main Results:

• The hyoid bone, despite its classification, is extensively connected to the skull base, mandible, tongue, larynx, and scapular belt.
• It is crucial for speech, respiration, mastication, and swallowing.
• It plays a key role in maintaining airway patency.

Conclusions:

• The hyoid bone is a critical anatomical structure with significant physiological functions.
• Comprehensive knowledge of hyoid bone anatomy and physiology is essential for diagnosing and managing related clinical conditions.
• Further attention is warranted to fully appreciate the hyoid bone's importance in human health.
