A 7-yeаr-оld child presents tо the clinic with mild eаr discоmfort аnd a sensation of fullness in the right ear. Upon examination, the tympanic membrane appears retracted but without fluid behind it. Tympanometry reveals negative middle ear pressure (Type C). The child has no fever, and no recent history of upper respiratory infection or ear pain. In a follow-up visit three weeks later, the child complains of hearing difficulty in the same ear, and an otoscopic exam reveals fluid behind the tympanic membrane, with a dull, slightly bulging appearance. Tympanometry now shows a flat (Type B) tympanogram, indicating the presence of fluid. Question: Based on this clinical progression, which of the following best describes the likely difference between the initial diagnosis and the current condition?
