A 14-year-old asthmatic patient presents for orthodontic evaluation. She has crowded lower anteriors, ectopic upper canines, lip incompetence, and a convex facial profile. All of the following are expected clinical findings EXCEPT:

Correct answer: D. Deviated nose (nasal deviation)

• A. Incorrect. Crowded lower anterior teeth IS the chief complaint.
• B. Incorrect. Lip incompetence IS expected — it was described in the case and is commonly associated with dental crowding and mouth breathing (where the lips cannot seal without effort).
• C. Incorrect. A convex facial profile IS expected — described in the case, consistent with dental crowding and possibly an underlying skeletal pattern.
• D. CORRECT. A deviated nose (nasal deviation) is NOT an expected finding in this clinical presentation. The case describes dental crowding, ectopic canines, lip incompetence, and a convex profile — typical orthodontic and possibly mouth-breathing findings. Nasal deviation is a separate anatomical variant unrelated to the described dental/orthodontic findings. This was the EXCEPT answer.
