The palatal perforation was in fair general condition, with weak sweating, poor appetite, often with low fever, a few with high fever, and ineffective treatment with general antibiotics. Local examination shows swelling, erosion and even ulceration of the nasal mucosa, which is granulomatous with grayish-white necrosis on the surface. Most of them involve the inferior turbinate or nasal septum first, which can lead to swelling and bulging of the external part of the nose, and the development of the lesion can lead to septal perforation or palatal perforation. So what are the factors that cause palatal perforation?
1, congenital factors Palatal perforation as a congenital developmental defect, with growth and development, the deformity also changes with age, including the physical developmental defects of the deformity itself, surgical trauma caused by secondary changes in the shape of the jaw, language, hearing and other functional disorders, as well as the psychological barriers formed by patients in social interaction.
2, tumor factors Malignant granuloma mostly begins in the nose, and then gradually extended to the midline of the face, is a rare granuloma with progressive necrotic ulcers as clinical features. The etiology of this disease is unknown, and the pathological examination is mostly chronic non-specific granulation tissue and necrosis, in which there are multiple components of inflammatory cell infiltration. Because of the variety of pathological entities, there are many names and classifications, such as necrotizing granuloma. Lethal midline granuloma, midface idiopathic granuloma and midline malignant reticulocytosis. At present, the clinical custom is to use malignant granuloma.
3, traumatic factors Perforation of the palate can present difficulty in swallowing and produce sound changes, fixation, destruction and perforation of the soft palate can lead to food reflux into the nasal cavity; upward or outward invasion of the nasopharynx or parapharyngeal space can have dental closure, mouth opening difficulties, otitis media, temporal pain and occasional cranial nerve involvement.
All of these symptoms can lead to palatal perforation symptoms.
