Slater PW, Rizer FM, Schuring AG & Lippy WH (1997): Practical use of total and partial ossicular replacement prostheses in ossiculoplasty. 42 year-old male with no significant medical history presenting to ENT clinic after referral from PMD for perforated TM. Since then, the patient has not had any further ear pain or discharge but is left with persistent and constant hearing loss and ringing (high-pitched, non-pulsatile). AD: Decreased acuity to finger rub, EAC with some cerumen, cleared to reveal central perforation in posterior-superior quadrant of tympanic membrane. Wegener’s granulomatosis.18 TinnitusThe mechanism underlying tinnitus is not well-understood.

We will strive to meet the demands of your communication needs as realistically as is possible, being governed by the configuration of your hearing loss and the latest technology available to us. Focusing on one speaker in a crowded or noisy environment is often especially difficult for a person with a hearing loss. In a car, the engine, road or wind noise can make it hard to hear a conversation, the radio or important traffic sounds. People with a hearing loss frequently feel that others mumble or need to repeat what they’ve said. Often, a person will hear, but not understand, what’s being said, and ask for repetitions. In church, theatres, and auditoriums, it might be very difficult to for that someone to hear a speaker’s voice, and ask repeatedly to sit closer to the front of the hall.

Someone cupping their hand behind their ear, or turning the ear towards the sound source is commonly seen in people having hearing difficulties, but it’s no substitute for a properly fitted hearing instrument.
Added to this, differential diagnosis in the early stage of the disease is exceedingly difficult because the clinical manifestations are common to a number of skin and neurological diseases (Bolognia et al, 2012).
It is easy to imagine that false positive identifications abound in areas where the disease is endemic and false negatives are likely in areas where the disease is virtually unknown. Leprosy was claimed to originate along the Nile in ancient Egypt (Lucretius) but few if any mummified remains show evidence of leprosy in that region. Things got worse in the middle ages, when leprosy continued to be viewed as a contagious scourge brought on as divine punishment by God. Other than divine intervention, about the only humane treatment seems to have been baths, which were a popular treatment in some Christian areas to cleanse lepers of their sins.
Just as the Hebrews brought leprosy out of Egypt, leprosy spread with immigration to western Europe that accompanied the decline of the Roman Empire and the Crusades. Not much changed for centuries, even though science discovered bacteria and discarded Galen’s bodily humors theory. Audiologists can breathe a sigh of relief that Paracelcus did not prevail in the treatment of leprosy, since the effect of mercury toxicity on the auditory nerve is well known. The patient last had normal hearing approximately 1yr ago when he noted acute onset of right ear pain, discharge, hearing loss and ringing in the setting of fever and a productive cough. The patient describes a history suggestive of acute otitis media complicated by TM perforation. Background noise, such as music or group conversations, can become overwhelming, making it impossible to participate in a conversation.

This is long into the infection, meaning that by definition, the diagnosis is invariably delayed. Finally, persistent disease stigma is an obstacle to diagnosis, since victims from ancient times forward have hidden the condition as long as possible if leprosy is suspected (Harrison, 1986). Lepers were viewed as sinners who brought the disease on themselves and apparently acted under God’s orders as they spread it to other sinners.

He does not recall an inciting event (trauma, swimming) to this initial episode, and had no previous history of ear infections. Persistent perforation seen on examination today can result in the tinnitus and hearing loss the patient complains of. Within the community, precautionary hygienic protocols were part of daily life, designed to protect the community from leprosy and other diseases. He saw his PMD several days later, was told he had a perforated ear drum and was treated with antibiotics. However the marked sensorineural component remains unexplained, particularly given the patient reported previously normal hearing.
While there is some evidence that acute otitis media can lead to sensorineural hearing loss, it is typically only mild and only in high-frequency ranges.1,2  Plan for further evaluation with repeat audiogram and MRI IAC, RTC when studies completed.
