The cervical sinus is a structure formed during embryonic development. It is a deep depression found on each side of the neck. It is formed as the second pharyngeal arch (hyoid arch) grows faster than the other pharyngeal arches, so they become covered. The first pharyngeal arch (mandibular arch) also grows slightly faster.

cervical sinus a temporary depression in the neck of the embryo containing the branchial arches.

A deep and narrow cervical sinus with a steady stream of accumulated blood overflowed in the lower part of the cervix, and a normal uterine cavity was found. Laparoscopic adhesiolysis and enucleation of the cystic structure that connected to the sinus tract then were performed.

2022年1月3日 · Sinus infections happen when there’s inflammation in your sinus cavities. They can cause many symptoms, including neck pain. While neck pain isn’t a hallmark sign of a sinus infection, it’s...

Branchial arch anomalies represent 20 % of cervical neck masses in children and typically result from incomplete obliteration of branchial clefts with subsequent formation of cysts, fistulae and sinus tracts.

Congenital cysts, sinuses and fistulas of the head and neck are uncommonly detected in children. They include congenital craniofacial and cervical anomalies; the latter may be mediocervical or latero-cervical in position. Surgical excision of these lesions is the only option of treatment.

Branchial cysts and fistulas are remnants of embryo structures of the neck with later onset in adulthood. Clinical exam is straightforward but needs additional information through imaging studies. Cervical ultrasonography, CT, and MRI enable visualizing structure details, local extension, and neighboring vascular axes.

The edges of cervical sinus in the due course fuse and hence in life no defect is seen. However, it is the persistence of intervening ectoderm that gives rise to branchial cyst. The branchial fistula results from breakdown of the endoderm, usually in the second pouch.

2016年8月27日 · Cervical teratomas are usually midline, mixed cystic and solid, show rapid growth, and cause greater degree of mass effect upon the airway and esophagus and secondary polyhydramnios when compared with goiter.

2024年5月17日 · The upper cervical spine, specifically the top two vertebrae (the atlas and axis), plays a significant role in sinus function. Misalignments in this area can directly impact the trigeminal nerve, leading to a variety of sinus-related issues.
