nasal cyst
Introduction
Introduction to nasal cysts Nasal cysts are generally divided into three categories according to the anatomy: 1 The primordia is derived from the surface fissure cyst of the fusion of the cranial and facial parts of the embryonic period (more common nasal vestibular cyst); 2 the odontogenic cyst occurring in the upper bone (including periodontal cysts and dental cysts); 3 cysts that occur in nasal congestion (commonly with mucosal cysts and mucinous cysts). basic knowledge Sickness ratio: 0.0001% Susceptible people: no specific people Mode of infection: non-infectious Complications: cerebrospinal fluid leakage
Cause
Cause of nasal cyst
Congenital blindness abnormalities (25%):
Due to congenital or dysplastic cysts, there are various facial fissures, such as a lacrimal cyst, a nasal-nose line-like cyst, a fistula, a cleft lip and palate cyst, a sinus cyst, an incisor bone cyst, a nasal vestibular cyst, and a dental cyst. Wait. Most of them are developed by the residual of the embryo at the junction or fusion during the development process. The nasal vestibular cyst can also be caused by obstruction of mucous gland ducts at the bottom of the nasal cavity and retention of secretions. As for the tooth cyst, it may be developed from the normal tooth follicle during tooth development.
Gland obstruction (30%):
Cysts caused by retention of glandular secretions (such as nasal vestibular cysts) can be caused by obstruction of the glandular duct; sinus mucosal cysts are also secreted, and are sometimes referred to as mucus retention cysts or submucosal cysts.
Stimulation of inflammatory infections (30%):
A cyst caused by an infection stimulus (such as a periodontal cyst occurring in the maxilla) is caused by a cyst-like change in the apical granulation tissue after infection or injury of the root; and a mucinous cyst occurring in the maxillary sinus is a non-secretory type. The pseudocyst formed by the sinus chronic inflammation causing damage to the submucosal capillary wall and accumulating slurry accumulates in the loose connective tissue in the sinus mucosa, also known as serous cyst. In addition, sinus mucus cysts can also be caused by trauma. Surgery, tumor inflammation and other factors block the sinus ostium, resulting in retention of sinus secretions.
Prevention
Nasal cyst prevention
1. Prevent serious scarring of the skin after surgery.
2, surgical attention points: the fistula is located in the nose and face, is an important part of affecting beauty, should choose the correct incision, the fusiform incision around the fistula should be consistent with the skin lines, to completely remove the fistula, but also to retain the normal tissue to the maximum, reduce Postoperative defects.
3, should pay attention to the repair of defects, if the defect is large, should pay attention to tissue repair such as transplanted skin.
Complication
Nasal cyst complications Complications cerebrospinal fluid leakage
After treatment and healing, it may leave scars and affect the appearance. Cerebrospinal fluid leakage may occur.
Symptom
Nasal cyst symptoms Common symptoms Nasal mucosa swelling Cerebrospinal fluid Rhinorrhea respiratory abnormalities
1, the larger one may have the same side nasal cavity blocked, the nose or upper lip swell.
2. The attachment of one side of the nose is raised and touches the elastic and soft mass.
3, combined infection, the cysts increase rapidly, local pain is obvious.
Examine
Examination of nasal cysts
Auxiliary inspection
1. The general sinus cyst examination project is based on the inspection frame limit "A".
2. The odontogenic cyst or the tumor identification test project may include "A", "B" and "C".
Diagnosis
Diagnosis and identification of nasal cysts
Differential diagnosis
According to the clinical manifestations, because the symptoms are clear, no identification is needed.
