Li Tongxue, 18 years old, rode a motorcycle from Taibei to Yilan a year ago. It is suspected that it is because the riding time is too long, and I feel abnormal pain in the coccyx, and gradually there is repeated pus. Sitting on the hard floor is more painful, but he has been seeing a doctor in a medical institution and can't find the cause. He sought the help of plastic surgery because of his fate and was diagnosed as a rare disease "diving". After the operation, he finally stopped fidgeting.

Zheng Xutang, a plastic surgeon at the Affiliated Hospital of Asian University, pointed out that "pilonidal sinus", also known as "pilonidal sinus", is a rare sinus with hair on the skin. This kind of sinus is most common in sacrococcygeal region, and it is usually difficult to heal itself. Sometimes misdiagnosed as * * * catheter, local cellulitis infection or skin abscess.

Submucosal disease is a rare acquired disease, which affects about 26 out of every 654.38 million people in the United States. Common in men, people with strong body hair and obesity. It usually happens after puberty, and it is rare under 654.38+07 years old. 654.38+increased gradually after the age of 09, and reached the peak after the age of 25. In World War II, the incidence rate in Britain and America was high.

Latent hair disease is mainly caused by gravity pulling the upper half of sacrococcygeal fissure, and the skin is involved in the most vulnerable part at the bottom of hair follicle, which causes repeated acute and chronic abscesses, or repeatedly overflows the sinus of secretion, accompanied by hair that grows out of the sinus and is not connected with the surrounding skin. If there is no infection, it is often asymptomatic, only the sacrococcygeal bulge is felt, and sometimes the sacrococcygeal pain and swelling are felt.

In terms of treatment, Zheng Xutang explained that when there is an abscess in acute infection, it is necessary to cut and drain the abscess to deal with the infection problem; If it belongs to the chronic stage of the disease, it is recommended to carry out complete surgical resection, and try to completely remove the granulation tissue and hair in the cavity, so as to strive for a chance of cure. At the same time of resection, skin flap transfer operation is needed to cover the * * * area after sinus resection. The advantage of this operation is that the resection range of diseased tissue is the largest, and the wound is sutured by transferring skin flap, with low tension and high healing probability.
