Introduction

Introduction Saliva is a mixed fluid secreted by large and small salivary glands. The regulation of salivation is completely neuro-reflective, including unconditioned and conditioned reflexes. The efferent nerves that innervate the salivary glands have sympathetic and parasympathetic nerves. Both of these nerves excite when they cause an increase in salivary secretion, but mainly by the role of parasympathetic nerves. In general, infants and young children under 1 year old are drooling because of their small oral volume, large saliva secretion, and stimulation of the gums. Pediatric hooliganism is drooling, which refers to a condition in which saliva does not consciously overflow from the mouth.

Cause

Cause

Reasons for increased salivation:

There are many reasons for hooliganism in infants and young children, some of which begin to linger in 2-4 months after birth, and more and more in the future, especially at 5-6 months. This is because the salivary glands have not developed well at the time of birth. After 3-4 months, the development gradually matures, and the secretion of saliva gradually increases. When the teeth are released in 5-6 months, the local nerves are stimulated, and the salivary glands are secreted more. At this time, children are not used to swallowing saliva, and the mouth is shallow, so the saliva keeps flowing out, which is a normal physiological phenomenon.

As you get older, this phenomenon will go away when your child can swallow too much saliva. Parents don't have to be nervous and don't have to be treated. If you are still over 3 years old, drooling should be combined with mental development and motor development. If growth, intelligence, and movement develop behind, then drooling is a manifestation of mental retardation. Oral occlusion is not correct, the mouth is closed poorly, and it is easy to cause saliva overflow. Otherwise it is not necessarily a problem.

If there is not much saliva, it will suddenly increase in the short term, or it can swallow excess saliva. Once it has not flowed, and then there will be rogue, then you should observe whether the child is crying or fever, and then see if the buccal mucosa is congested. No ulcers or white spots. If facial paralysis occurs, or other nervous system changes, causing facial and oral muscle movement disorders, affecting the child's swallowing, chewing is prone to drooling. The doctor should be asked to further examine the cause for treatment.

Adenoid hypertrophy in the throat, or severe allergic rhinitis often requires mouth breathing. The action of swallowing saliva is less, and the situation of saliva overflow is more common, so it should be treated according to this situation.

Diagnosis of increased salivation

1, physiological hooliganism

(1) Food stimulates children 4-6 months after birth, most of them use breast milk as the main food. During this period, there were no teeth in the mouth of the child. The tongue was short and wide, the cheeks had a thick layer of fat, the facial muscles developed well, and the mucosa of the jaws thickened and raised. These structural features were all about catching the nipple and coordinating during feeding. The sucking action is very beneficial. At this time, the function of the salivary gland is not large, and the amount of saliva secretion is small. After 4-6 months, breastfeeding alone can not meet the needs of children's growth and development, began to add complementary foods, food stimulation of nerves, salivary glands is stronger, so that salivary gland secretion function is enhanced, saliva is significantly increased.

(2) When the deciduous teeth develop, the gingival sensory nerves will be mechanically stimulated, so that the salivary glands secrete more saliva. At this time, the children's oral cavity is shallow, the swallowing reflex is not sensitive, and the excessive saliva cannot be swallowed in time, resulting in Saliva accumulates in the mouth and overflows. With the eruption of the deciduous teeth, the secretion of saliva will gradually become normal, and the odontoids will gradually form, the crotch will gradually increase, the bottom of the mouth will gradually deepen, and it will be able to accommodate more saliva, and the swallowing action will gradually mature and be able to saliva. Ingested in time, the flow is natural.

2, pathological hooliganism

(1) Long breastfeeding time Some mothers mistakenly believe that the longer the breastfeeding, the better, extend breastfeeding to 1 year old, and even add complementary food after weaning. This practice is not conducive to the normal development of spleen and stomach in children, Chinese medicine believes that sputum is the spleen of the spleen, the spleen and stomach are weak, lost in the adjustment, and therefore drooling, and often accompanied by indigestion.

(2) mechanical damage of the parotid gland Some children's parents and relatives and friends are pinching the cheeks of the child. This method is easy to cause mechanical damage to the parotid gland, resulting in the secretion of saliva much more than normal children, resulting in hooliganism.

(3) Oral inflammation Many oral inflammations, such as catarrhal stomatitis, bacterial infectious stomatitis, herpes virus caused by herpes virus, etc., can stimulate the secretion of salivary glands and cause salivation. At this time, the saliva flowing out is mostly yellow or bloody. , smell skunk, often accompanied by fever, irritability, refusal to eat and other symptoms.

Diagnosis

Differential diagnosis

Differential diagnosis of increased salivary secretion:

Saliva and sweat reduction are clinical manifestations of acute total autonomic dysfunction. Acute total autonomic dysfunction is more common in children and adults. It is characterized by extensive or incomplete paralysis of the autonomic nerves, such as blurred vision, abnormal pupillary response to light and regulation, large pupils, and decreased or disappeared secretion of tears, saliva and sweat. And urinary retention, impotence, gastrointestinal dysfunction (nausea, vomiting, constipation, bloating or diarrhea) and abnormal body temperature regulation.

Salivary gland enlargement: mucous cyst of salivary gland, generalized flow mucus cyst including small flow gland cyst and sublingual cyst, is a more common salivary adenoma-like lesion. Parotid cysts are divided into two categories: retention and congenital. The former is rare. Benign hypertrophy of salivary glands, also known as salivary gland enlargement or salivary degeneration, is a non-tumor, non-inflammatory, chronic, recurrent, painless, swollen salivary gland disease.
