This man has Kartagener syndrome, which has immotile cilia due to a dynein arm defect (FA2020 p49)

Important question parts that point to Kartagener syndrome:

• Recurrent sinusitus and bronchitis - lack of motile respiratory cilia predisposes these individuals to upper respiratory tract infections
• Potential infertility - he is 35 and he is married with no children (though it never mentioned he had tried for children), individuals with this defect have immotile sperm and thus reduced fertility
• *Point of maximal impulse at the 4th intercostal space on the right - This is indicative of *situs invertus which is heavily associated with Kartagener syndrome. This is probably the "buzz" for the question that should point you to the diagnosis and therefore answer
• The nasal polyps with squamous metaplasia are also associated with Kartagener syndrome
