Congenital parotid cyst symptoms?

summary

The cervical cysts were first reported by huczovsky (1785), and then named as branchial cleft cysts, supralymphatic cysts and so on. In 1932, Ascherson named it branchiogenic cysts, which is widely accepted and still used today. It is called branchial fistula when the two ends of the duct are connected.

Congenital parotid cyst symptoms?

Neck or pharynx often have intermittent swelling or pain, especially when swallowing is more obvious, there is a history of upper feeling before onset. Some patients reported a sense of pressure on the neck, pharyngeal stretch and so on.

Occasionally, low fever and hoarseness may occur. Examination showed local protrusion or fullness, cervical sinus secretion overflow, gradually increasing neck mass. Choiss et al. (1995) counted 52 cases, among which the most common three symptoms were cervical fistula secretion, cervical mass and repeated infection.

Most of them were cysts, fistulas and involved skin (Fig. 1-4). The incision can be trapezoidal, S-shaped or Y-shaped, or along the anterior edge of sternocleidomastoid muscle or combined. If the fistula is located in the palatopharyngeal arch, the palatine tonsil can be removed at the same time as cyst, fistula, internal and external fistula. For lesions originating from the fourth branchial arch, the posterior part of the thyroid cartilage should be removed to expose the piriform fossa. Double purse string ligation and suture should be performed at the internal orifice or cyst root after resection. For recurrent cases, Blackwell et al. (1994) suggested that functional neck dissection should be used for complete resection.

matters needing attention

At present, there are mainly two theories. One of the etiological theories is the residual of branchial organ, which is mainly considered as follows: ① incomplete closure of the second branchial sulcus and rupture of the closure membrane between the branchial sulcus and the pharyngeal sac; ② Persistent or patent carotid sinus; ③ Thymopharyngeal duct residue; ④ Chromosome dominant genetic abnormality. The lesions originated from the second, third and fourth gill organs. Another theory is cystic change of cervical lymph tissue. GOLLEGE (1994) confirmed that there were lymphoid follicles in the inner wall of the cyst, which may be the palatine tonsil epithelium protruding into the lymph nodes and stimulating Lymphocystic changes.
