Second branchial apparatus
cysts are the most common and account for up to 95% of all branchial apparatus
The second theory suggests that the cysts are derived from the remnant of branchial apparatus
. (7) Because the dorsal portion of (2) nd branchial pouch blends with first pouch there is still controversy regarding which pouch contributes to the nasopharyngeal branchial cyst.
FIRST BRANCHIAL CLEFT CYSTS: First branchial apparatus
anomalies account for 5 % to 8 % of all branchial anomalies are usually in the form of a cyst or sinus (4).
Intraoperative fistulograms in the management of branchial apparatus
abnormalities in children.
Nonetheless, a general understanding is evident regarding how the components of the head and neck anatomy are derived from the branchial apparatus
. As with all anatomy, many variations from the textbook norm are possible, and small alterations in a complex process can lead to unusual abnormalities.
Cysts, fistulas, and sinuses of the second branchial cleft are the most common developmental anomalies arising from the branchial apparatus
. In our case, a 43-year-old man ...
The branchial apparatus
, which gives rise to a wide array of structures that originate in the cervical area, is organized into arches, pouches (endoderm), and clefts (ectoderm).
Branchial cleft anomalies occur as a result of an incomplete obliteration of the branchial apparatus
during fetal development.
During fetal development, structures between the head and heart arise from the branchial apparatus
. Of the six branchial arches in humans, the fifth and sixth are rudimentary.
