概括
在冠状喉造形术中,精确地定位前腔管 (AC) 是至关重要的,以避免声脱落. 这项研究发现,AC通常距离甲状腺软骨边界6-10mm,建议在手术期间使用安全边缘.
科学领域:
- 喉腔病理学 喉腔病理学
- 手术解剖学手术解剖学
- 声音女性化手术 手术
背景情况:
- 在冠状腺造术期间,准确地识别甲状腺软骨前部 (AC) 是非常重要的,以防止声 (VF) 损伤.
- 女性化喉膜整形术 (FemLar) 结合了声音的女性化和部形状的改善.
研究的目的:
- 描述在手术期间识别AC水平的手术内方法.
- 在此过程中确定甲状腺软骨切除的安全下限.
主要方法:

Muscles of the Anterior Neck
4.4K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Larynx
4.0K
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,...

The Hyoid Bone
4.5K
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...
