What's the reason for heavy nasal sounds

summary

The nasal sound caused by the inability to close the nasal cavity is also called open nasal sound. That is to say, this book does not suffer from other diseases. When it makes a sound, it needs to close the nasal cavity. When it resonates, it can not be closed, but it is still in an open state. When making a sound, the air flow can continuously rush up from the throat into the nasal cavity, making the sound ambiguous. There are two kinds of nasal sounds, one is open nasal sound, the other is occlusive nasal sound. The latter is the most common nasal sound, mostly caused by nasal obstruction. So, how to diagnose the nasal sound caused by the nasal cavity can not be closed? Let's take a look at the following.

What's the reason for heavy nasal sounds

First: open nasal is mainly caused by nasal obstruction, the most common is a cold when the nasal congestion. All the pathological changes that cause nasal obstruction will cause occlusive nasal sound. As long as the nasal obstruction is removed, the nasal sound can be removed. We need attention!

Second, pathological nasal sounds are divided into open nasal sounds and occlusive nasal sounds. When there are cleft palate or soft palate paralysis and other diseases, the soft palate closes the nasopharynx, and the nasal cavity loses its relatively fixed space and volume. If the nasal cavity resonates abnormally, it is accurate to pronounce. It is the "distortion" of some syllables, and there is open nasal sound and language communication.

Third: in contrast to open nasal sounds, occlusive nasal sounds are caused by new organisms occupying the nasal cavity or reducing the volume of the nasal cavity. Typical diseases include hypertrophic turbinate, huge nasal polyps, nasal hemangioma and other benign lesions, as well as paranasal sinus malignant tumor invading the nasal cavity (such as maxillary sinus cancer), posterior nostril atresia or stenosis are also common.
