Dr Kirt Simmons responds:

As an orthodontist I have an "idea" about what's going on- I surmised your son is a teenager from his post about junior varsity sports? The "maxillary deficiency" does in fact mean that his upper jaw is deficient, generally this term would be used in the context of his whole head and face and if his bottom jaw was too large ("acromegalic"- actually refers to the large jaw which occurs due to too much growth hormone in ADULTHOOD) it would be described as "mandibular excess" or "mandibular prognathism". MOST CA individuals have a small top jaw and a normal size (although the shape may be "different") bottom jaw- which looks large compared to the top jaw. This is usually best treated by orthodontics (braces) to line the teeth up correctly over each jaw bone and then having a surgical procedure to line the jaws up correctly. Most cases of top jaw smallness can be corrected by just top jaw surgery, it DEPENDS ON THE INDIVIDUAL CASE (ALL this discussion is generalities of course). With more specific information I could address your question more specifically. It is generally best to delay the surgery until facial growth is complete, or nearly so. Otherwise the patient may "grow out of" the correction. Hope this is helpful.
