Nasal cyst is going to happen?

Nasal cyst because of the location and material contained within the cyst and the causes vary by different names. According to the host can be divided into parts by the wall occurred in the nasal cavity or nose within weeks of soft tissue facial cleft cyst, If the nasal dorsum midline dermoid cyst with the nasal vestibule cyst; occurred on the bone from the odontogenic cysts and nasal obstruction occurred in the nasal mucosal cysts such as cysts, and other mucous cyst. By cyst material contained ingredients can be divided into different degrees cyst, cyst containing tooth, mucosal cysts, mucocele, gas cyst and on this basis, because of the infection and formation of pus Lu stay cyst. According to the cause of the blind can be divided into congenital anomalies, because obstructive not gland secretion and retention infection and inflammation factors stimulating, and so on. Because of inherent genetic or developmental abnormalities in a variety of cleft cyst cyst, such as Alar below cleft cyst, nasal dorsum of the center line and fistula cyst, cleft lip and palate cyst, nose palate cysts, bone cysts and incisor nasal vestibule cyst, cyst containing teeth and so on. More than one in the development process from the surface in the process of integration of the engagement or the remnants of the embryos developed. While they may be nasal vestibule cyst at the end of the nasal mucous glands obstruction, secretions caused by retention. As for the cyst may contain teeth in the tooth development process, the teeth from normal follicular development comes. Within gland secretions caused by retention cysts (As mentioned above the nasal vestibule cysts) may obstruction caused; sinus mucosa cyst secretory also resulting, which sometimes also known as the mucus retention cysts or submucosal cyst. Infections caused by the cyst stimulus (such as occurred in the maxilla periodontal cyst) is the root infection or injury, apical granulation tissue caused by a cyst-like changes; occur in the maxillary sinus cyst such as non - mucus secreted , was due to chronic sinus inflammation of the mucosal damage exudative capillary wall of the sinus mucosa serous accumulated in the loose connective tissue formation in the pseudocyst, also known as serous cysts. In addition, sinus mucocele also may trauma. Surgery, tumor blocked sinus inflammation, and other factors mouth, causing sinus secretions caused by retention. From the description above can be seen, more types of nasal cyst, the same causes may cause different parts of the nose cyst, and the same cysts also can be a combination of factors contributed. This also indicates the complexity of its causes. Clinical work, it must have a clear understanding of the diversity and complexity, in order to grasp the characteristics of various nose cyst.
