Sir, I would argue that there is no need for Mr Mew to invent a new name for what is commonly (in the orthodontic world at least) known as 'long face syndrome' or 'adenoid facies'. The debate about what causes this appearance has been ongoing for about 100 years. There is some evidence that changes in the shape of the mandible occur post-adenoidectomy but also there is evidence that the shape of the face is NOT related to the degree of nasal breathing; the difficulty in trying to find the truth is due to the complex interplay between multiple factors that are both genetic and environmental. Mr Mew has developed a treatment therapy based on his ideas and, irrespective of the theory behind it, we need to see how successful it is.

If one accepts that having a soft diet, chronic nose breathing and not swallowing correctly are causing some malocclusions (Mr Mew thinks about 30% according to statements on the Internet which seems an unlikely figure) then good luck to anyone trying to change them. One must not let the elegance, or otherwise, of a theory drive a therapy with a low success rate. I don't think this is defeatist, just pragmatic.
