ICD-10: M26.1

ICD-10 code M26.1 refers to "Anomalies of jaw-cranial base relationship," which encompasses a range of conditions affecting the alignment and relationship between the jaws and the cranial base. This classification is part of the broader category of dentofacial anomalies, which includes various malocclusions and structural irregularities of the facial skeleton.

Clinical Description

Definition

Anomalies of jaw-cranial base relationship involve deviations from normal anatomical relationships between the maxilla (upper jaw), mandible (lower jaw), and the cranial base. These anomalies can lead to functional issues, aesthetic concerns, and may impact overall oral health.

Types of Anomalies

1. Skeletal Classifications: These anomalies are often classified according to skeletal relationships, such as:
   - Class I: Normal occlusion with a slight discrepancy in jaw relationships.
   - Class II: Retrognathism, where the mandible is positioned further back than the maxilla.
   - Class III: Prognathism, where the mandible is positioned forward relative to the maxilla.

2. Craniofacial Dysostosis: Conditions like Crouzon syndrome or Apert syndrome can lead to significant jaw-cranial base relationship anomalies due to abnormal skull and facial bone development.

3. Other Conditions: Other anomalies may arise from congenital factors, trauma, or developmental issues, leading to asymmetries or malformations.
