Macroglossia Health Dictionary

Professionally trained speech therapists assist, diagnose and treat the whole spectrum of acquired or developmental communication disorders. They work in medical and education establishments, often in an advisory or consultative capacity. The medical conditions in which speech therapy is employed include: dysgraphia, DYSLEXIA, DYSARTHRIA, DYSPHASIA, DYSPHONIA, DYSPRAXIA, AUTISM, BELL’S PALSY, CEREBRAL PALSY, DEAFNESS, disordered language, delayed speech, disordered speech, DOWN’S (DOWN) SYNDROME, LARYNGECTOMY, LEARNING DISABILITY, MACROGLOSSIA, MOTOR NEURONE DISEASE (MND), malformations of the PALATE, PARKINSONISM, STAMMERING, STROKE and disorders of voice production.

Speech therapists form a small independent profession, most of whom work for the National Health Service in community clinics, general practices and hospitals. They may also work in schools or in units for the handicapped, paediatric assessment centres, language units attached to primary schools, adult training centres and day centres for the elderly.

A speech therapist undergoes a four-year degree course which covers the study of disorders of communication in children and adults, phonetics and linguistics, anatomy and physiology, psychology and many other related subjects. Further information on training can be obtained from the College of Speech Therapists.

If the parents of a child are concerned about their child’s speech, they may approach a speech therapist for assessment and guidance. Their general practitioner will be able to give them local addresses or they should contact the district speech therapist. Adults are usually referred by hospital consultants.

The College of Speech Therapists keeps a register of all those who have passed a recognised degree or equivalent quali?cation in speech therapy. It will be able to direct you to your nearest NHS or private speech therapist.... speech therapy

Conditions of the tongue At rest, the TONGUE touches all the lower teeth and is slightly arched from side to side. It has a smooth surface with a groove in the middle and an even but de?nite edge. It is under voluntary control and the tip can be moved in all directions.

Ankyloglossia or tongue-tie is a rare disorder in which the frenum or band connecting the lower surface of the tongue to the ?oor of the mouth is so short or tight that the tongue cannot be protruded. Surgery can remedy the defect. It is easy to overdiagnose and is not a common cause of di?culty in feeding at birth or speech defects in infancy.

Gross enlargement of the tongue can make speech indistinct or make swallowing and even breathing di?cult. This is known as macroglossia and may be such that the tongue is constantly protruded from the mouth. The cause may be CONGENITAL, as in severe cases of DOWN’S (DOWN) SYNDROME, or it may occur as a result of ACROMEGALY or be due to abnormal deposits as in AMYLOIDOSIS.

A marked tremor of the tongue when protruded may be seen in various neurological diseases, but may be caused by alcoholism.

After a STROKE involving the motor nerve centre, the control of one side of the tongue musculature will be lost. This will result in the protruded tongue pointing to the side of the body which is paralysed. The sense of taste on one side of the tongue may also be lost in some diseases of the brain and facial nerve.

The presence of fur on the tongue may be obvious and distressing. This is due to thickening of the super?cial layers of the tongue which may appear like hairs which trap food debris and become discoloured. Furring is common during fever and as a result of mouth-breathing and smoking.

In some conditions the tongue may appear dry, red and raw (GLOSSITIS). An in?amed beefy tongue is characteristic of pellagra, a disease caused by de?ciency of NICOTINIC ACID in the diet. A magenta-coloured tongue may be seen when there is a lack of RIBOFLAVIN.

Ulcers of the tongue are similar to those elsewhere in the mouth. The most common are aphthous ulcers which are small, red and painful and last for about ten days. They are associated with stress, mild trauma (such as from jagged teeth), and occasionally with folic acid and vitamin B12 de?ciency. Ulcers of the tongue are sometimes found in patients with chronic bowel disease.... tongue, disorders of
