Facial Reconstruction From an Edentulous Damaged Skull
An unidentified skull is brought to a forensic artist. The medical examiner estimates the person was female, 35 to 50 years old, and of European ancestry, based on cranial morphology. The skull is edentulous, the mandible is broken at the left angle, and the maxilla has a healed defect above the left incisor region. No DNA or dental records are available yet. The local media have learned about the case, and a detective asks for a face to release within 72 hours to generate tips. The artist has access to a CT scan, tissue-depth tables for European females, and a database of facial features but no antemortem photographs. The detective suggests adding a distinctive scar because a missing woman in a neighboring county has one. What should the artist do?
1. What reconstruction approach is defensible given the skull condition and available data?
Read the worked answer
A CT-based three-dimensional reconstruction, or a carefully documented two-dimensional reconstruction from the CT views, is defensible if the artist treats the result as an approximation rather than a portrait. The artist should reconstruct the broken mandible at the left angle, using the contralateral side and anatomical symmetry as a guide, and should note that the repair is an inference. Edentulism affects the lower face substantially: without teeth, the maxilla and mandible resorb, the mouth may appear more closed, and the lower facial height and lip support are uncertain. The artist should use tissue-depth tables appropriate to the estimated sex and ancestry, but should not present the depths as exact. The healed maxillary defect should be documented as an observed feature; it may or may not have produced a visible scar in life. The artist should produce neutral, multiple views and avoid adding hairstyle, eye color, or a specific scar unless supported by evidence.
2. How should the artist respond to the detective's request to add a distinctive scar?
Read the worked answer
The artist should decline to add the scar from the missing woman in the neighboring county. That request would build the reconstruction around a preferred identification and create confirmation bias: viewers who know the missing woman's scar may read a resemblance into the image, and the family may interpret the image as confirmation. The healed maxillary defect is a real finding, but its visible expression is unknown, and it should not be converted into a specific scar location without evidence. The artist should explain that a reconstruction must be based on the skull and documented soft-tissue evidence, not on an unrelated case. If the detective wants to test a possible match, that should be done through DNA or dental comparison, not by altering the facial approximation. The artist should document the request and the reason for refusal in the case file.
3. What should the release include and what limits should be stated?
Read the worked answer
The release should state that the image is a facial approximation based on the skull, not a photograph or a positive identification. It should note the estimated sex, age range, and ancestry, the edentulous condition, the repaired mandible, and the uncertainty in lip support and lower-face contour. The image should be neutral, without hairstyle or eye color, and should be released with more than one view if possible. The agency should ask for tips about the deceased's identity and should explain that DNA or dental comparison is required for identification. The 72-hour deadline is a media pressure, not a scientific constraint; if the reconstruction is not ready, the artist should say so rather than release an overconfident face. The artist should retain the CT files, depth tables, reconstruction steps, and any revisions.
