Patients with palatal perforation are in fair general condition, with weak sweating, poor appetite, often with hypothermia and rarely with hyperthermia, and ineffective treatment with general antibiotics. Local examination shows swelling, erosion and even ulceration of the nasal mucosa, which is granulomatous and has a grayish-white necrotic surface. Most of the lesions involve the inferior turbinate or the nasal septum first, and in obvious cases, the external part of the nose may swell and bulge. The repair method of palatal perforation and effective prevention of palatal perforation are as follows: 1. In principle, the repair is carried out under tension-free using local tissue flaps of the palate as much as possible. The design of the local mucoperiosteal flap can be flexible and varied depending on the location of the palatal perforation, but the basic surgical approach is the same, using a double-layer repair of local tissue whenever possible. Smaller perforations located in the anterior palate or on one side can be repaired with a local mucoperiosteal flap transfer. The method is to use the edge of the fistula as the tip and design a mucoperiosteal flap that flips to the nasal side as a lining for the nasal surface, with the lining tissue counterstitched and knotted on the nasal side. Then, a mucoperiosteal flap is designed to cover the perforation in the direction of the blood vessel travel.
2, a reasonable diet can be more intake of high fiber and fresh vegetables and fruits, balanced nutrition, including protein, sugar, fat, vitamins, trace elements and dietary fiber and other essential nutrients, meat and vegetables, food variety diversification, give full play to the complementary role of nutrients between foods, is also very helpful in the prevention of this disease.
3, the prevention of palatal perforation is to strengthen the preventive measures of the primary disease, pay attention to oral hygiene, maintain local cleanliness and timely medication, as long as after appropriate treatment, the prognosis is good.
