Oral Surgery/Reduce length


QUESTION: I would like to know if it's possible to reduce midface length, and by midface I mean the distance between the glabella and nasal base. Mine is too long (8 centimeters to be exactly), and the other areas of my face, which are the upper face (Hairline to the glabella) and lower face (Nasal base to the base of the chin) are only 7 centimeters. I thought that a maxillary impaction could help me but it would only reduce the length of my lower face.

ANSWER: Vinicius, It is possible to reduce the height of the midface by impacting the maxilla. You must remember that that impaction will also reduce the height of the lower face because the the stop of the lower teeth is now superiorly placed. To correct for this, a genioplacty or a sliding horizontal osteotomy of the chin should be performed. I hope that helps

QUESTION: Thank you so much for your answer but I have another question, you say that a maxillary impaction would reduce the height my midface, but as far as I know the maxillary impaction would only reduce the height of my maxilla, but the maxilla is located below the nasal base, it's located in the lower face, not in the midface. Thanks again.

The impaction of the maxilla will take with it the anterior nasal spine which is part of the maxilla. It is also the base of the measurement of the lower portion of the midface. This is why it will change the measurement of the midface. I hope that clears things up.
