A teenage girl with crowded teeth who uses albuterol for asthma presents for orthodontic evaluation. What facial profile finding would most likely be observed?

Crowded teeth in adolescents are often associated with skeletal Class II malocclusion, which presents with a convex facial profile. In Class II, the maxilla is protruded relative to the mandible, creating a prominent upper lip and retruded chin. Albuterol (a beta-2 agonist used for asthma) does not directly affect skeletal development but chronic mouth breathing due to asthma can contribute to vertical growth patterns. The convex profile is the most likely finding in a patient with dental crowding and a Class II skeletal pattern.
