Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that due to getting hit with the dodge ball there has been traumatic injury to the inside of the ear and as you already have
Microtia that is an underdeveloped outer ear also known as Pinna, both the conditions have led to n increased
hearing loss..
As there is pain and pressure in ear after getting hit along with loss of hearing there is a possibility that you have got raumatic injury to the ear drum leading to perforation..
It is a matter of concern and you should consult an Otolaryngologist and get evaluated and a thorough clinical evaluation can help in diagnosis and treatment can be done accordingly..
In case if there is perforation and it is small, a course of antibotics, anti-inflammatory painkillers like
Ibuprofen, decongestants and antibiotic and
analgesic ear drops can relieve..
In case of large perforation surgical correction that is
Tympanoplasty can be advised..
Hope this information helps..
Thanks and regards.
