Bednar's aphthae K12.0

A. Bednar, 1850

Traumatically caused, sometimes persistently persistent, aphthous ulcers, e.g. in infants, appearing as so-called suction ulcers on the posterior lateral parts of the hard palate. In paediatric literature also known as Riga feather disease.

In larger obstetric collectives, Bednar's aphthae are found in 18.5% of infants. No correlation between sex and occurrence of the ulcers. However, they are less common in breastfed children than in formula-fed babies.

In infants triggered by wiping out the oral cavity or by habitual suction of the oral mucosa.

Especially in early infancy. Aetiologic and clinically comparable ulcers are also described in older age.

Mostly solitary, 0.3-0.8 cm large, circumscribed fibrin-coated, moderately painful, firm, ulcerated, chronic plaque (more rarely an ulcer reaching below the level of the mucous membrane) with raised marginal areas. In adults, the clinical picture must be distinguished from denture ulcers caused by chronic irritation of poorly fitting dentures.

Avoid mechanical irritation, e.g. use smaller suction cups with larger holes.

Spontaneous healing within 3-6 days after removal of the cause.

It remains to be seen to what extent the so-called oral eosinophilic ulcer (eosinophilic ulcer: Sugaya N et al. 2018), also called traumatic ulcer, is identical with the Bednar's aphthae.
