nasopharyngeal angiofibroma
Introduction
Introduction to nasopharyngeal angiofibroma Nasopharyngeal angiofibroma is a common among various benign tumors of the nasopharynx. It often occurs in young men between the ages of 10 and 25, with a male to female ratio of 19:1. The tumor is rich in blood vessels and is prone to hemorrhage. Therefore, it is also known as "male anaerobic nasopharyngeal angiofibroma", which can explain the characteristics of this disease. According to the opinion of most scholars, growth may be stopped after the age of 25, and there is no recurrence after surgery. The tumors disappeared during the follow-up. The cause of this disease is unknown. The tumor can occur in various parts of the body. The size is different, the surface is smooth, and it can be pushed freely. The fibroids can be divided into soft and hard. The soft fibroids are skin sputum, pedicled, soft, and more often. Neck and chest and back. basic knowledge The proportion of illness: 0.08% Susceptible people: good hair occurs in young men aged 10 to 25 Mode of infection: non-infectious Complications: anemia, tinnitus
Cause
Causes of nasopharyngeal angiofibroma
Cause:
The cause is unknown. The tumor can occur in all parts of the body. The size is different, the surface is smooth, and it can be pushed freely. The fibroids can be divided into soft and hard. The soft fibroids are skin sputum, pedicled, soft, mostly occurring in the face, neck and Chest and back.
Prevention
Nasopharyngeal angiofibroma prevention
In young men under the age of 25, this disease occurs mostly in young men aged 10-25 years. Anyone with progressive nasal congestion and a large amount of paroxysmal sudden nosebleed should be alert to the possibility of this disease and go to the hospital for examination. Surgical treatment is performed promptly after diagnosis.
Complication
Nasopharyngeal angiofibroma complications Complications, anemia, tinnitus
The disease is often easy to cause major bleeding, the tumor can be compressed to cause bone destruction, into the sinus, eyelids, cranial cavity, so the pathology is benign, clinically may cause serious consequences.
Symptom
Symptoms of nasopharyngeal angiofibroma Common symptoms Nasal congestion, nosebleeds, repeated bleeding, ear suffocation, nose, nose, nose
According to the symptoms and examination results, gender, age, susceptibility to typical patients, because this tumor is very easy to bleed, generally do not do biopsy, X-ray film and CT have a certain diagnostic value for tumor size, expansion direction and range, foreign scholars Radiation imaging staging according to CT examination: stage I, tumor located in the nasopharynx, posterior nares and sphenoid sinus; stage II, tumor protruding into the nasal cavity, ethmoid sinus, maxillary sinus, buccal and medial or outward expansion In the third stage, the tumor expands outward into the infraorbital fossa and axillary fossa, buccal and lateral iliac crest; in stage IV, the tumor expands into the skull. The disease has characteristic clinical manifestations, but must be associated with nasopharyngeal malignant tumors. Differentiation of fibrous nasal polyps and posterior nostril polyps, malignant tumors have different hiatus manifestations than this disease, tumors develop rapidly, early cervical lymph node metastasis, biopsy can confirm the diagnosis, nasal polyps are soft, not easy to bleed, palpation is easy to move, mostly The pedicle originates from the nasal cavity or sinus.
(1) Bleeding: It is a main symptom, and it can be repeatedly hemorrhagic in the early stage, paroxysmal, and the amount is large, so that it is accompanied by different degrees of secondary anemia.
(B) clogging and compression symptoms: after the blockage of the nostrils in the nostrils, began to one side, gradually developed into bilateral, oppression of the eustachian tube mouth, hearing loss, tinnitus, destruction of the skull base invasion of the cranial nerve, there are headaches and cranial nerves Paralysis, invading the eyelids, pterygopalatine fossa or armpits, causes the eyeball to protrude, the cheeks or ankles to bulge, and the downward development of the soft palate, and the tumor is visible in the oropharynx.
Examine
Examination of nasopharyngeal angiofibroma
Nasopharyngoscopy: It can be seen that the nasopharynx has a round, reddish mass, smooth surface, and the blood vessels are clearly visible. The palpation is hard, fixed, and easy to bleed. The nose is sometimes seen with a reddish mass in the nasal cavity.
X-ray and CT examination can understand the size, extent and skull base of the skull.
In recent years, angiography has been performed to observe the blood supply of the tumor and the expansion to the brain for reference during surgery.
Diagnosis
Diagnosis and diagnosis of nasopharyngeal angiofibroma
The disease has characteristic clinical manifestations, but must be differentiated from nasopharyngeal malignant tumors, fibrous nasal polyps and posterior nostril polyps. Malignant tumors have different hiatus manifestations than this disease. The tumors develop rapidly and have early cervical lymph node metastasis. The biopsy can be performed. Confirmed, nasal polyps are soft, not easy to bleed, palpation is easy to move, and many pedicles originate from the nasal cavity or sinuses.
