Clinical photograph of the patient
This patient had soft swelling measuring about 6 x 5 cms just below the angle of the jaw.
The mass was soft and compressible. No gurgling sound was heard on compression.
It showed a dramatic increase in size on valsalva maneuver.
Investigations:
Xray soft tissue neck lateral view
X ray soft tissue neck lateral view: showed air filled sac.
CT scan axial view of neck:
Showed air filled sac in the neck extending from the interior of larynx. Probable diagnosis "External laryngocele"
Discussion:
Laryngoceles are air filled sacs usually in continuity with laryngeal air column. This was first described by
Virchow in 1863. These masses were said to be intimately related to the laryngeal ventricle. Usually
they are in continuity with the ventricle. It is of three types:
1. Internal laryngocele - Confined to the interior of larynx
2. External laryngocle - This laryngocele prolapses through a rent in the thyrohyoid membrane and presents usually as a neck mass
3. Combined laryngocele - Both internal and external components of the laryngocele are seen in this type
These patients usually present with:
1. Hoarseness of voice
2. Breathlessness
3. Cough
4. Mass in the neck
Management:
This patient was taken up for surgery. Laryngocele was totally removed using external approach.
