[1] In young children this may result in pulling at the ear, increased crying, and poor sleep. [1] Decreased eating and a fever may also be present. [1]
Most causes of conductive hearing loss can be identified by examination but if it is important to image the bones of the middle ear or inner ear then a CT scan is required. CT scan is useful in cases of congenital conductive hearing loss, chronic suppurative otitis media or cholesteatoma, ossicular damage or discontinuity, otosclerosis and ...

[3] [4] This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold. [5]: 28 Most infections are viral in nature, and in other instances, the cause is bacterial. [6] URTIs can also be fungal or helminthic in origin, but these are less common. [7]: 443–445

[6] A third form, malignant otitis externa, or necrotising otitis externa, is a potentially life-threatening, invasive infection of the external auditory canal and ...
The pathophysiology of mastoiditis is straightforward: bacteria spread from the middle ear to the mastoid air cells, where the inflammation causes damage to the bony structures. Streptococcus pneumoniae , Streptococcus pyogenes , Staphylococcus aureus , Haemophilus influenzae , and Moraxella catarrhalis are the most common organisms recovered ...
Long term otitis media (or 'glue ear') [2] Insertion of a tympanostomy tube. [4] [5] [6] If aspiration is performed as part of the insertion, the risk of tympanosclerosis occurring increases.
