Symptoms and Signs – Differential Diagnosis of Drooling
Drooling, the expulsion of saliva from the mouth, occurs whenever there is an inability to swallow or retain saliva, or when there is excessive salivation. The etiology of this condition may be attributed to facial muscle paralysis or weakness that hinders the closure of the mouth, neuromuscular problems or local pain resulting in dysphagia, or, less frequently, the substances or toxins that stimulate salivation. Oral drooling can be either minimal or excessive (up to 1 liter per day) and can lead to discomfort around the mouth. Drooling indicates an incapacity to adequately manage secretions, thereby serving as a warning sign of possible aspiration.
Clinical Background and Physical Assessment
Before assessing the quantity, ascertain the extent of salivation exhibited by the patient. Is it sparse or profusion? When was it initiated? Inquire with the patient about the dampness of his pillow in the morning. Furthermore, examine for any discomfort around the mouth.
Next, investigate related indications and manifestations. Inquire about symptoms such as stiffness in the throat and challenges with swallowing, chewing, speaking, or breathing. Instruct the patient to provide a
Pain or rigidity in the facial and cervical regions, accompanied by muscular weakness in the face and peripheral limbs. Has he observed any alterations in mental state, such manifesting as somnolence or restlessness? Inquire about alterations in visual acuity, auditory perception, and gustatory perception. Request information regarding anorexia, weight loss, fatigue, nausea, vomiting, and changes in bowel or urinary patterns. Has the patient experienced a recent airborne illness or any other form of infection? Does he have a recent history of animal bites or chemical exposure? Lastly, acquire a comprehensive drug history.
Proceed to do a physical examination. Conduct a vital sign assessment of the patient. Observe for indications of facial paralysis or atypical facial expression. Assess the oral and cervical regions for edema, the pharynx for edema and erythema, and the tonsils for exudate. Note malodorous breath. Inspect the tongue for bilateral furrowing, often known as trident tongue. Screen for pallor, skin lesions, and frontal baldness. Thoroughly evaluate any signs of bites or punctures.
Conduct an evaluation of cranial nerves II, VII, IX, and X. Next, assess the size and sensitivity of the pupils to light. Evaluate the patient's linguistic abilities. Assess muscular strength and examine for either pain or atrophy by palpation. Furthermore, perform palpation to detect lymphadenopathy, particularly in the cervical region. Conduct an observation of the patient's swallowing capacity and evaluate his gag reflex. Conduct an assessment to identify impaired balance, hyperreflexia, and a positive Babinski's reflex. In addition, evaluate sensory function for paresthesia.
Medical Causes
Bell’s palsy. With Bell’s palsy, drooling accompanies the gradual onset of facial hemiplegia. The affected side of the face sags and is expressionless, the nasolabial fold flattens, and the palpebral fissure (the distance between the upper and lower eyelids) widens. The patient usually complains of pain in or behind the ear. Other cardinal signs and symptoms include unilateral diminished or absent corneal reflex, decreased lacrimation, Bell’s phenomenon (upward deviation of the eye with attempt at lid closure), and partial loss of taste or abnormal taste sensation.
Esophageal tumor
With an esophageal tumor, copious and persistent drooling is typically preceded by weight loss and progressively severe dysphagia. Other signs and symptoms include substernal, back, or neck pain and blood-flecked regurgitation.
Ludwig’s angina
With Ludwig’s angina, moderate to copious drooling stems from dysphagia and local swelling of the floor of the mouth, causing tongue displacement. Submandibular swelling of the neck and signs of respiratory distress may also occur.
Myotonic dystrophy
The persistent salivation in this condition can be attributed to facial weakness and a sagging jaw. Additional distinctive features include myotonia (impaired muscle relaxation following contraction), muscle atrophy, cataracts, testicular atrophy, frontal alopecia, ptosis, and a nasal, monotonous voice.
Peritonsillar abscess
In this abscess, a severe aching throat leads to dysphagia accompanied by moderate to abundant excretion of saliva. Presenting indications include a pronounced fever, sour breath, and swollen, reddish, edematous tonsils that may be concealed by a soft, gray exudate. Physical examination may detect cervical lymphadenopathy.
Pesticide poisoning
The toxic effects of pesticides may manifest as excessive salivation accompanied by drooling. Diaphoresis, nausea and vomiting, involuntary urine and feces, blurred vision, miosis, increased lacrimation, fasciculations, weakness, flaccid paralysis, symptoms of respiratory distress, and coma are among the other effects.
Rabies
When this acute central nervous system infection advances to the brain stem, it produces drooling, or “foaming at the mouth.” Symptoms of drooling include excessive salivation, facial palsy, or very painful pharyngeal spasms that reduce swallowing ability. In around 50% of instances, rabies is accompanied by hydrophobia. Before the patient presents with global flaccid paralysis and coma, seizures and hyperactive deep tendon reflexes may also manifest.
Generalised seizures
Generalised seizures are muscle reactions characterised by profuse salivation and frothing at the mouth, alongside loss of consciousness and cyanosis. During the unresponsive postictal state, the patient may also experience copious salivation.
Points of Special Consideration
Be vigilant for aspiration in the patient experiencing excessive salivation. Orient him either in an upright or lateral position. Maintain regular oral hygiene and apply suction as needed to manage excessive salivation. Come prepared to carry out a tracheostomy and intubation, to provide oxygen therapy, or to carry out an abdominal push.
To assist the patient in managing excessive salivation, offer a sealed and transparent container for collecting the saliva to reduce unpleasant smell and avoid the spread of infection. Ensure quick access to tissues and cover his chest with a cloth during meals. Promote good oral hygiene. Moreover, instruct the patient in activities aimed at enhancing the strength of facial muscles, if suitable. Provide him with exacting skin care, particularly in the oral and cervical regions, to avoid skin deterioration. To decrease the likelihood of maceration, it is advisable to apply cornstarch onto the neck.
Therapeutic Counseling for Patients
Explain to the patient his medical diagnosis and the proposed course of treatment. Demonstrate to the patient suitable exercises aimed at enhancing facial muscular strength. Educate the patient on proper hygiene and skincare techniques.
Guidelines for Pediatric Populations
The ability to regulate saliva flow in infants often develops around the age of 1, coinciding with the maturation of muscle reflexes responsible for swallowing and lip closure. During the process of teething, which starts around the fifth month of life and continues until around the age of 2, salivation and drooling usually intensify. Excessive salivation and drooling can also arise as a reaction to hunger or the expectation of eating, and in connection with sickness.
Typical etiologies of excessive salivation include epiglottitis, retropharyngeal abscess, acute tonsillitis, stomatitis, herpetic lesions, esophageal atresia, cerebral palsy, mental impairment, and drug withdrawal in newborns of mothers with addiction. Furthermore, dysphagia can also be caused by the presence of a foreign object in the esophagus.
