Congenital hypothyroidism
|
|
|
A thyroglossal duct cyst occurs when parts of the thyroglossal duct persist and thereby form a cyst.
most commonly located in the - |
midline near the hyoid bone
but may also be located at the base of the = |
tongue;
it is then called a lingual cyst. |
|
it is very important to differentiate between an
ectopic thyroid and accessory thyroid to prevent = |
to prevent inadvertent surgical removal
|
|

Sublingual thyroid gland results from incomplete descent of thyroid
If present it is the = |
the only thyroid tissue present
|
|
|
________ thyroid tissue is the most common of ectopic thyroid tissue =
|
Lingual
Lingual thyroid tissue |
|
|
Ectopic parathyroid gland:
The parathyroid and thymus migrate in a |
caudal and medial direction
+ |
; therefore, ectopic glandular tissue (parathyroid and thymus) may be found anywhere along the migratory path

thyroglossal duct.
|
|
|
frenulum is short and extends to the tip of the tongue
|
Ankyloglossia
|
|
|
Ankyloglossia (Tongue-Tie)
|
frenulum is short and extends to the tip of the tongue . This interferes with its free protrusion and may make breast-feeding difficult.
|
|
|
Bifid or Cleft Tongue:
|
Incomplete fusion of the lateral lingual swellings
This is a very uncommon anomaly. |
|
|
Microglossia – usually associated with micrognathia (underdeveloped mandible and recession of the chin) and limb defects =
