Congenital nasal dermoid cyst and fistula
Introduction
Introduction to congenital nasal dermoid cysts and fistulas More common under 10 years old, occasionally seen in adults. It often occurs outside the eye muscle cone, and is attached to the upper or middle upper wall of the iliac crest. It can be dumbbell-shaped, with a part inside the skull and the iliac crest. Nasal facial fistulas have different causes, and those born in the nose are caused by congenital dermoid cysts. The nasal passages are mainly caused by facial fissure cyst infection and dental disease. The cheeks are more common in dental diseases, maxillary osteomyelitis or upper jaw. Caused by bone and bone.

Cause
Congenital nasal dermoid cyst and fistula cause
Nasal facial fistulas have different causes, and those born in the nose are caused by congenital dermoid cysts. The nasal passages are mainly caused by facial fissure cyst infection and dental disease. The cheeks are more common in dental diseases, maxillary osteomyelitis or upper jaw. Caused by bone and bone.
Prevention
Congenital nasal dermoid cyst and fistula prevention
Prevent serious scarring of the skin after surgery. Surgical attention point: the fistula is located on the nose and face, which is an important part of affecting beauty. The correct incision should be selected. The fusiform incision around the fistula should be consistent with the skin pattern. The fistula should be completely removed, and the normal tissue should be retained to the maximum extent. Defects should pay attention to the repair of defects. If the defect is large, attention should be paid to tissue repair such as transplanting skin.

Symptom

First of all, the diagnosis should first be detailed in the history of the disease, to understand whether there is any cystic uplift, local infection, history of trauma, dental caries, etc., carefully check the position, direction, depth and path of the fistula, etc., can be carefully examined with a probe, if necessary, iodide angiography It is essential to form a "lesion" examination of the fistula, which requires dental filming, maxillary filming, and CT examination.
1. Occurs in the face, the outside of the eyebrow, the nasal roots, the occipital area, etc. The cyst is round, soft and painless, and has no adhesion to the skin, but it is not easy to push with the deep fascia or bone.
2. The contents are atherogenic, thick, containing exfoliated epithelial cells, sebum or hair.
The eyeball protrudes from the front and the bottom, can not be reset, no pulsation, no eye pain, and normal vision.
Examine
Congenital nasal dermoid cyst and fistula examination
1.B super performance: the echoes in the circle are circular or elliptical, and the boundary is clear. The strong echo group is visible, and the sound is strong and compressible.
2. CT manifestations: the density of the tumor is uneven, there may be a fat density zone, the adjacent bone wall may be concave or defective, and the cavity enlargement is rare.
3. MRI findings: Both tumor T1 and T2 weighted images have high signal intensity.
Diagnosis
Congenital nasal dermoid cyst and diagnosis of fistula
According to the clinical manifestations, because the symptoms are clear, no identification is needed.
