What is a 4th branchial cleft cyst?
Fourth branchial cleft cysts are sparsely prevalent and sporadically observed cases. They comprise 1 to 4% of all the branchial cleft anomalies [23,24]. Like third BCCs, these are common on the left aspect. They are typically situated in the thyroid gland and mediastinum.
Where is the fourth branchial arch?
Normal embryological development of the branchial apparatus shows that the fourth arch artery on the left side becomes part of the aortic arch during development, while the fourth arch artery on the right side becomes the proximal part of the right subclavian artery (18, 22).
Can a branchial cleft cyst return after surgery?
Although rare, there have been reports of malignancies in branchial cleft cysts, including papillary thyroid carcinoma and branchiogenic carcinoma. The outcome of surgery is usually good. But, cysts can recur, particularly if the surgery occurred during an active infection.
What does a branchial cleft cyst look like?
What is a branchial cleft cyst? Branchial cleft cysts are small fluid-filled sacs that may look like lumps under your skin on the side of your neck. Healthcare providers may refer to branchial cleft cysts as pharyngeal cleft cysts or as a type of neck mass. These cysts are congenital, meaning they’re present at birth.
What happens after branchial cleft cyst surgery?
The patient may shower or have a sponge bath at home one to two days after surgery, after the drain is removed. Recovery takes about a week. A follow‐up appointment about 1‐2 weeks after the surgery is typically made to check how the area is healing.
Is branchial cleft cyst surgery painful?
After any surgery, some pain is normal, but if it does not decrease or worsens, it may be abnormal and indicate infection or bleeding. Bleeding and infection are possible, as with any surgery.
What are the 4 pharyngeal arches?
In humans
| Pharyngeal arch | Muscular contributions |
|---|---|
| 3rd | Stylopharyngeus |
| 4th | Cricothyroid muscle, all intrinsic muscles of soft palate (including levator veli palatini) except tensor veli palatini |
| 6th | All intrinsic muscles of larynx except the cricothyroid muscle |
Is there a 5th pharyngeal arch?
