Evaluation and Management of Drooling



Evaluation and Management of Drooling
Presentation by:Karen Stierman, M.D. & Ronald Deskin, M.D.

* Drooling - serious medical and social problem
o maceration, infection, soiling of clothes and belongings, effects on caregiver
* Sialorrhea - increase in salivary flow
* Drooling - ineffective saliva management

Anatomy and Physiology of Drooling
* Three pairs of major salivary glands - parotid, submandibular, and lingual
* 70% of saliva comes from the submandibular glands at the resting state
* Ingestion of food causes parotid gland to secrete a higher percentage of saliva

Submandibular and Sublingual gland innervation
Parotid innervation
Salivary gland innervation
Functions of saliva
* Protective
* Swallowing
* Digestion
* Speaking

Etiology of Drooling
* Acute vs. Chronic
* Direct vs. Indirect

Pathophysiology of Drooling
* Multifactorial
* Primarily a defect in the oral phase of swallowing caused by:
o poor head control, inability to close the mouth, abnormal tongue mobility, reduced intra-oral sensation
* Sialorrhea can lead to drooling caused by:
o medications and poor fitting dentures

Diagnosis of Drooling
* History - severity, peak time, influencing factors, associated conditions, parental expectations, age and mental status of the patient
* Physical - Head posture, dental abnormalities, nasal and oral cavities, decreased intraoral sensitivity
* Other - lateral neck x-ray, audio, barium sw.

Treatment Options
* Pharmacological therapy
* Speech therapy
* Behavioral therapy
* Radiation therapy
* Surgery
* Initial approach is usually nonsurgical and reversible

Pharmacological therapy
Speech therapy
Behavioral therapy
Radiotherapy
Surgical options
* Submandibular duct rerouting
* Submandibular duct excision
* Parotid duct ligation
* Transtympanic neurectomy

Surgical indications
* Age 5-6
* Assess ability to interact with peers
* Failed nonsurgical management
* Stable neurological status

Rerouting of submandibular duct
* Success rate of 80-100%
* Cuff of mucosa dissected around duct and marked medially and laterally
* Duct dissected 3-4 cm or until gland reached
* Tonsil used to create a tunnel just posterior to anterior tonsillar pillar and sutures passed with duct
* Tonsillectomy performed if obstructive tonsils
* Sublingual adenectomy(Crysdale) versus ligating sublingual ductules(Cotton)
* Advantages: Decreased xerostomia, problems with taste and dysphagia
* Disadv: Ranula, FOM swelling, sialoadenitis, sialolithiasis, aspiration

Studies on submandibular duct rerouting
Submandibular Gland Excision
Parotid duct ligation
Transtympanic neurectomies

Summary

* Goal: decrease drooling and provide healthy oral cavity
* Order of management controversial
o Nonsurgical management first
o Submandibular duct rerouting
o Submandibular gland excision +/- parotid duct ligation
o Tympanic neurectomy

o Thickness 1mm
o Height
+ Upper 10mm
+ Lower 4mm
* Orbicularis Oculi
o Orbital
o Palpebral
+ Preseptal
+ Pretarsal
* Medial canthal tendon
o Anterior reflection
o Posterior reflection
o Vertical fascial support
* Lateral canthal tendon
* Lateral retinaculum
* Orbital septum
o Origin
+ Arcus marginalis
o Insertion
+ Medial: posterior lacrimal crest
+ Lateral: orbital tubercle
+ Superior: levator aponeurosis

Treatments for Meniere’s Disease



Treatments for Meniere’s Disease
Presentation lecture by:Alan L. Cowan, MD

Tomoko Makishima, MD, Ph.D
Definition:Meniere’s Disease is a disorder of the inner ear that can affect hearing and balance.

History
Physiology
* Perilymph
o Located in the Scala Vestibuli / Tympani
o Similar in composition to CSF
o High Na+, Low K+
* Endolymph
o Located in the Scala Media
o Similar in compostion to ICF
o Low Na+ High K+
o Site of production in Stria Vascularis
* Membranous Labyrinth separates the compartments
o No difference in pressure

Pathophysiology
* Endolymphatic hydrops leads to distortion of membranous labyrinth
* Reisner’s membrane can be seen bulging into the scala vestibuli in some histologic studies
* Microruptures may lead to episodic attacks which resolve when the tears heal
* Theories behind endolymphatic hydrops
o Obstruction of endolymphatic duct/sac
o Hypoplasia of endolymphatic duct/sac
o Alteration of absorption of endolymph
o Alteration in production of endolymph
o Autoimmune insult
o Vascular origin
o Viral etiology

Diagnosis
* Meniere’s is diagnosed by
o Vertigo
+ Spontaneous, lasting minutes to hours
+ Recurrent, must have more than 1 episode
+ Associated with nystagmus
o Hearing loss
+ Fluctuating sensorineural
+ Low-frequency or flat
o Tinnitus
* Vertigo treatment reporting standard
* Hearing treatment reporting standard

* Meniere’s is diagnosed by
o Vertigo
+ Spontaneous, lasting minutes to hours
+ Recurrent, must have 2 episodes > 20 min.
+ Nystagmus during episodes
o Hearing loss
+ Avg (250, 500, 1000) 15 dB < Avg (1000, 2000, 3000) or
+ Avg (500, 1000, 2000, 3000) 20 dB > than other ear
+ For bilateral disease Avg (500, 1000, 2000, 3000) > 25 dB in the studied ear
o Tinnitus
+ No guidelines
o Aural pressure
+ No guidelines

* Possible Meniere's
* Probable Meniere's disease
* Definite Meniere's disease
* Certain Meniere's disease
* Functional Level Scale

Endolymphatic Sac Surgery
* Types of procedures
o Decompression: removal of bone overlying the sac
o Shunting: placement of synthetic shunt to drain endolymph into mastoid
o Drainage: incision of the sac to allow drainage
o Removal of sac: excision of the sac. Some believe the sac may play a role in endolymph production
