Q18.5 | Microstomy |
ICD-10 online (WHO version 2019) |
The microstomy (from ancient Greek μικρός micro , small 'and'Mouth', also 'mouth', 'opening') is a congenital or acquired mouth that is too small or an opening that is too small.
If only hypoplasia of the lower jaw is present, it is called micrognathia .
Spread and causes
The frequency is not known. Acquired microstomy can be found in up to 10% of burns and electrical accidents in the mouth area during the growing age and in over 30% of cases of scleroderma . A postoperative growth disorder after tumor removal in the mouth area, a CREST syndrome or forms of epidermolysis bullosa are among the causes of an acquired microstomy.
In the context of syndromes
A microstomy is found as a feature of some syndromes :
- Auriculo-condylar syndrome
- Burton syndrome , synonym: Kniest-like dysplasia with pursed lips and Ectopia lentis
- Desbuquois Syndrome
- Edwards Syndrome
- Femoral-Facial Syndrome
- Fine-Lubinsky syndrome , synonym brachycephaly - deafness - cataract - mental retardation
- Freeman-Sheldon syndrome and its variant Sheldon Hall syndrome
- Hallermann Streiff Syndrome
- Michelin Tire Baby Syndrome , synonyms: Michelin Tire Baby Syndrome; Skin folds, multiple ring-shaped, of the extremities; CCSF; Kunze-Riehm syndrome; Michelin tire baby syndrome; MTBS , AD, mutations in the MAPRE2 gene at 18q12.1-q12.2
- Multiple pterygium syndrome
- Oro-palatal dysplasia Bettex-Graf
- Oto-palato-digital syndrome type 2
- Richieri-Costa-Pereira Syndrome , synonyms: RCPS; Robin sequence with cleft mandible and limb anomalies , AR, mutations in the DDX48 gene at 17q25.3
- Simosa syndrome , synonym: face, flat - microsomia - ear anomalies; Blepharophimosis - Telekanthus - Microstomy;
- Syndromic Microphthalmia 5 , AD, mutations in the OTX gene at 14q22.3
- X-linked OHDO syndrome , XLR, mutations in the MED12 gene at Xq13.1
Clinical manifestations
Clinically, the focus is on the reduced opening of the mouth, in addition there are functional restrictions with articulation difficulty when speaking, problems with brushing teeth and possible dental treatment.
