What is the hidden hair sinus?

My butt is always going through puberty, and my acne keeps coming back and forth. How can I regain my confidence when my buttocks are pockmarked and not looking as good as others? Today, we are going to uncover the mystery of buttocks acne – the hidden hair sinus.

1, the hidden hair sinus is a divine acne?

It is a chronic sinus tract within the soft tissue of the sacro-caudal buttock cleft, most of which contains hair. In acute attacks, it can also appear as an acute abscess in the sacrococcygeal area, and after it breaks down, it forms a chronic sinus tract, which often recurs and does not heal for a long time.

The hidden hair sinus also has a wonderful name – jeep disease, because the disease is very common in the Second World War on the buttocks of British and American soldiers, found that they all have a similar point – a long ride in a jeep, so the disease is called jeep disease.

2.How does the hidden hair sinus occur?

There are two theories for the formation of hidden hair sinus: one is a congenital disease, caused by the residual medullary canal or the developmental malformation of the sacrococcygeal suture resulting in a congenital defect of the skin there, causing the epidermis to fold inward; the other is an acquired disease, sinuses and cysts are granulomatous diseases caused by injury, surgery, foreign body irritation and chronic infection, and the sinus tract does not heal easily. The twisting and friction of the buttocks during walking causes the hairs between the gluteal middle fissure to pierce the nearby skin and form short ducts, while the hairs are still connected to their root, and the short ducts then epithelialize. When the hair has the original follicle shed, it is gravitationally inhaled by the epithelialized short duct.

Risk factors: local injury, hard hair, sedentary occupational habits, body mass index greater than 25, poor personal hygiene, local irritation and trauma, etc.

3.The “first judgment” of hair hiding sinus Patients can see skin depression in the midline of sacrococcygeal area, with irregular small holes, about 1~3 mm in diameter, usually with the history of repeated infection and septic rupture or surgical incision to drain pus. In the early stage, the symptoms are recurrent swelling, pain and foreign body infection in the sacrococcygeal region with limited cyst formation, and in the late stage, the symptoms are cyst infection and formation of superficial abscess that breaks down by itself. Typical symptoms are acute abscess or chronic secretory sinus in the sacrococcygeal area, with acute symptoms such as local fever, pain, squeezing pain, and systemic clinical manifestations of acute infection such as fever chills in those with acute infection.

4, the treatment of Tibetan hair sinus Tibetan hair sinus treatment methods are diverse, various treatment methods have their advantages and disadvantages. No single treatment method can treat all the problems caused by the disease. Clinicians evaluate in detail the scope and characteristics of each patient’s specific lesion, as well as the patient’s social environment and economic conditions before treatment, and choose the most suitable treatment plan for the patient.

(1) Surgical treatment The treatment is simple, i.e. cross-incisional drainage under local anesthesia, with the incision chosen where fluctuations or pressure pain is most pronounced, avoiding the median line. Antibiotics are not a substitute for surgical drainage. Antibiotic treatment may be added for abscesses with cellulitis, or when the patient has diabetes, vascular heart disease or immunodeficiency. Postoperatively, the wound is frequently checked for healing, the surrounding hair is shaved, the sinus cavity is gently probed with a probe, or it is possible to pull out a tuft of hair which acts as a foreign body and perpetuates the infection. After the above treatment, some patients’ wounds may heal in one phase, but most of them still do not heal after 1 to 2 months and are chronic and recurrent, so that radical surgical treatment of the hidden hair sinus is needed.

No method of radical surgery for chronic hidradenitis can be proven to be completely successful. Extensive excisional surgery has been used in the past, but has proven to be slow to heal, causing unnecessary pain and loss to the patient. Currently, more conservative surgery is used to remove only the diseased tissue while preserving as much normal skin and subcutaneous tissue as possible.

(2) Non-surgical treatment Anti-infection treatment, sclerotherapy, fibrin glue plugging, etc. have a high failure rate and inaccurate long-term efficacy.
