Macrotia can be simply defined as an ear that is excessively large in size. By direct measurement, the vertical height of the normal ear is a range of 55-65 millimeters in the adult patient. Another method of assessing overall size is comparing the ratio of width to height. Normally, this ratio should be 50-55%. Whenever either of these two measurements is beyond the normal range, the ear can appear excessively large - and be a source of concern for many patients suffering from macrotia... In most cases, macrotia results from an enlarged scapha. So what is the scapha of the ear you may be asking? The scapha is shown more visually (in yellow) in the adjacent patient photo and corresponds to the upper one-third of the ear. More specifically, the scapha is the more flattened portion of the ear that is bordered by the upper helical rim. Normally, the scapha is a fairly narrow segment that separates the helical rim from what is called the antihelix. This is shown in the adjacent photo..
