Branchial Fistula / Sinus :-
1. Branchial Fistula / sinus is a congenital anomaly i.e. present from birth due to persistence of branchial apparatus remnants.
2. This is a tiny hole in the lower part of the neck formed by incomplete closure of the second branhcial arch. The sinus is frequently associated with a track running up the neck, often as high as the posterior pillar of the fauces in the pharynx (so forming a branchial fistula)
3. The condition is normally observed in children, most often in the first year of life. It presents as a small orifice discharging muous in the anterior border of the sternomastoid, one-third of the way up the muscle's origin.
4. Treatment is a surgical excision, dissesting the fistula out as high as possible.

Glomus Vagale :-
1. Glomus Vagale tumor arises from paraganglia in and around the Xth Cranial Nerve or Vagus Nerve.
2. Tumors of the paraganglia are called "paragangliomas", "glomus tumors" and "chemodectomas".
3. Paraganglia are normal structures that develop from the neural crest; they accompany cranial nerves and cluster around cranial nerve ganglia.
4. Most comman paraganglioma of neck are Carotid body tumor and next is Glomus Jugulare tumors. Glomus Vagale tumors are the third common most.
5. Embolization followed by surgery is the treatment choice.
6. When surgery is not possible, then therapeutic embolization and radiotherapy are alternatives.
