Long face syndrome is a condition where the facial features appear elongated and narrow. This condition can impact a person's overall facial structure, causing abnormalities in the jaw, mouth, and nose. Some synonyms for long face syndrome include: facial elongation, mandibular elongation, dolichocephaly, and protragism. Long face syndrome can also be referred to as a skeletal Class II malocclusion, which describes the relationship between the upper jaw and the lower jaw. People with long face syndrome may experience dental and orthodontic problems due to misaligned jaws, crowded teeth, or bite issues. Treatment options for this condition may include corrective surgery or orthodontic interventions.
