Laryngocele arises from
| A |
True cords |

Subglottis |
|

The saccule is a diverticulum of MUCOUS membrane which starts from the anterior part of ventricular cavity and extends upwards between vestibular, .folds and lamina of thyroid cartilage. When its abnormally enlarged it forms the air containing sac – the laryngocele.
Laryngoceles can be classified into three types:
- Internal – A laryngocele is defined as internal if the dilatation lies within the limits of the thyroid cartilage.
- External – If the laryngocele extends beyond the thyroid cartilage and protrudes through the thyrohyoid membrane producing a lateral neck mass, it is considered external.
- Combined – In which both internal and external components are seen.
Causes
Due to raised transglottic air pressure as in trumpet players, glass blowers or weight lifters.
Clinical symptoms.
External laryngocele presents as a reducible swelling in the neck which increases in size on coughing or performing valsalva
Patient may present with hoarseness, cough, dyspnea, dysphagia or a foreign body sensation.
Treatment
If symptomatic the management would consist of
.) For small lesion
Lamyngoscopic decompression.
2.) For larger lesions
Surgical excision through external approach.
Laser endoscopic excision.
External laryngocele is a herniation that arises from which of the following membrane?
| A |
Thyrohyoid membrane |
|
| B |
Cricoepiglottic membrane |
|
| C |
Thyroid membrane |
|
| D |
Cricovocal membrane |

A laryngocele is an air filled herniation of the saccule of the laryngeal ventricle.
It is caused by a prolonged increase in intraglottic pressure in patients with a predisposing long sacculus. Laryngoceles are of two types internal and external.
Internal laryngocele: are confined within the larynx and appear as cystic swellings of the aryepiglottic fold.
External laryngocele: extend through the thyrohyoid membrane and lie lateral to the thyroid cartilage.
An old man presented with hoarseness, cough, dysphagia, and foreign body sensation in the throat. Laryngocele was suspected. Laryngocele arises from herniation through:
| A |
Cricothyroid membrane |
|
| B |
Thyrohyoid membrane |
|
| C |
Laryngeal fold |
|
| D |
None of the above |

A laryngocele is defined as an abnormal dilation or herniation of the saccule of the larynx.
Laryngoceles can be classified into three types: internal, external, and combined.
A laryngocele is defined as internal if the dilation lies within the limits of the thyroid cartilage.
If the laryngocele extends beyond the thyroid cartilage and protrudes through the thyrohyoid membrane producing a lateral neck mass, it is considered external.
