Fresco of Approving of bylaw of Society of Jesus depicting Ignatius of Loyola receiving papal bull Regimini militantis Ecclesiae from Pope Paul 3.
This group bound themselves by a vow of poverty and chastity, to "enter upon hospital and missionary work in Jerusalem, or to go without questioning wherever the pope might direct". They called themselves the Company of Jesus, and also Amigos En El Senor or "Friends in the Lord," because they felt "they were placed together by Christ." The name had echoes of the military (as in an infantry "company"), as well as of discipleship (the "companions" of Jesus). An in-vitro comparison of the disintegration of human ear wax by five cerumenolytics commonly used in general practice.

The outer ear consists of the auricle (unlabelled), the external auditory canal, and the lateral surface of the tympanic membrane (TM).
There are several other audiological tests that are also commonly abnormal in persons with conductive hearing loss. Tympanometry usually is either flat (as shown below), or shows an abnormally large volume (indicating a perforation). Other tests that may be helpful in confirming conductive hearing loss are OAE testing and temporal bone CT scan.
Causes include a buildup of ear wax, a foreign body in the ear canal, otosclerosis, typanosclerosis (as shown above), superior canal dehiscence (which can also cause a conductive hyperacusis), external or middle ear infections (otitis externa or media), allergy with serous otitis media (fluid in middle ear), trauma to the ossicular chain such as temporal bone fracture, tumors of the middle ear such as a glomus tumor, erosion of the ossicular chain (cholesteatoma) and perforation of the tympanic membrane.
A hole in the ear drum, which is called a tympanic membrane perforation, causes a conductive hearing loss.
It is generally attributed to previous ear infections or trauma (such as a tube insertion). The last step in the chain of signal transmission between sound in the air and movement of fluid in the inner ear is the middle ear. There are three small bones interposed between the large ear drum, and the small hole (oval window) across which sound is transmitted into the inner ear. Complete ossicular chain discontinuity usuall results in a large, flat conductive hearing loss.
Characteristically, hearing aids work well for conductive hearing loss, and very good hearing results can be obtained.
Surgical treatment is also generally available for conductive hearing loss as it is always due to a mechanical problem. Most surgical treatments for otosclerosis or middle ear disease involve opening of the middle ear and repair under direct vision. However, in our opinion (which is not representative of general opinion of ear surgeons), we think it is preferable to use a hearing aid until hearing becomes unservicable, and then move onto an implanted hearing aid, and skip the middle ear surgery part altogether. It is intended for general informational purposes only and does not address individual circumstances. Ignatius of Loyola, who after being wounded in a battle, experienced a religious conversion and composed the Spiritual Exercises to closely follow Christ. The fresco was created by Johann Christoph Handke in the Church of Our Lady Of the Snow in Olomouc after 1743. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Hearing loss can be divided into two main categories: Conductive hearing loss (CHL) occurs because of a mechanical problem in the outer or middle ear.
The middle ear includes the medial surface of the eardrum, the ossicular chain of bones, the eustachian tube. These can be immensely troublesome because their removal can be difficult, and infections are common. It is more accurate to say that there is a hearing reduction, as generally hearing is not greatly affected -- a 10 db drop is typical.
There also seems to be a weak association with increased serum calcium (de Carvalho et al, 2006) . When these bones are fused (otosclerosis, or ossicular fixation) or broken (ossicular chain discontinuity), a conductive hearing loss is the inevitable result. When combined with a sensorineural hearing loss, this pattern may look superficially like a conductive hearing loss, because there is an air-bone gap. Persons with LVAS may develop hearing loss as well as be unusually vulnerable to inner ear disease associated with head injury. Recently some groups (Kakehata et al, 2006) are using endoscopy for repair of ossicular chain disturbances -- in our opinion, this is still very investigational and somewhat unreasonable -- when working inside a tiny space, one needs as good an exposure as one can manage.

In fact, 2 out of 3 times, when kids get colds, they also wind up with infections in their ears.

The three tiny bones of the ear (ossicles) may not conduct sound properly, or the eardrum may not vibrate in response to sound.
These are most easily removed using an examining microscope, but in some instances, surgical removal is needed. It is presently thought that persons taking calcium supplements are not at increased risk, and also that there is no risk from calcium channel blocker medications.
The most common ones are cholesteatoma associated with chronic ear infection (it is not a true tumor) and glomus tumors.
The main reasons are that their immune systems are immature and that their little ears don’t drain as well as adults’ ears do.
Never ignore professional medical advice in seeking treatment because of something you have read on the WebMD Site. Fluid in the middle ear can cause this type of hearing loss. Sensorineural hearing loss (SNHL) results when there is a problem with the inner ear. Practically, this is a very uncommon situation, of much more interest to diagnosticians than patients. The ear is divided anatomically into three sections (external, middle, and inner), and pathology contributing to hearing loss may strike one or more sections. It most often occurs when the tiny hair cells (nerve endings) that transmit sound through the ear are injured, diseased, do not function properly, or have prematurely died.
This type of hearing loss is sometimes called "nerve damage," although this is not accurate. CHL is often reversible. But even if your kid hasn’t been swimming, a scratch from something like a cotton swab (or who knows what kids stick in there?) can cause trouble. Leading causes of conductive hearing loss include cerumen impaction, otitis media, and otosclerosis. Leading causes of sensorineural hearing loss include inherited disorders, noise exposure, and presbycusis.


People who have both forms of hearing loss are said to have mixed hearing loss. Causes Ear infections are the most common cause of temporary hearing loss in children. An understanding of the indications for medical management, surgical treatment, and amplification can help the family physician provide more effective care for these patients.
Diagnosing an Ear InfectionThe only way to know for sure if your child has an ear infection is for a doctor to check inside her ear with a device called an otoscope. This is basically just a tiny flashlight with a magnifying lens for the doctor to look through. The differential diagnosis of hearing loss can be simplified by considering the three major categories of loss. Conductive hearing loss occurs when sound conduction is impeded through the external ear, the middle ear, or both. Wax softeners (like Cerumenex) may be needed if the wax is hard and stuck in the ear. Take care when removing foreign bodies. Sensorineural hearing loss occurs when there is a problem within the cochlea or the neural pathway to the auditory cortex. Inside Your EarThe Eustachian tube is a canal that connects your middle ear to your throat. Mixed hearing loss is concomitant conductive and sensorineural loss.EvaluationA thorough history and a careful physical examination are essential to the diagnosis and treatment of hearing loss. Fluid in the EarIf the Eustachian tube gets blocked, fluid builds up inside your child’s middle ear. This makes the perfect breeding ground for bacteria and viruses, which can cause infections.
An otoscope should be used to examine the external auditory canal for cerumen, foreign bodies, and abnormalities of the canal skin. Your doctor may look inside your child’s ear with an otoscope, which can blow a puff of air to make his eardrum vibrate.
The mobility, color, and surface anatomy of the tympanic membrane should be determined (Figure 1). Bursting an EardrumIf too much fluid or pressure builds up inside your child’s middle ear, her eardrum can actually burst (shown here).
The sound remains midline in patients with normal hearing.The Rinne test compares air conduction with bone conduction.
The good news is that the pain may suddenly disappear because the hole lets the pressure go. When the patient no longer can hear the sound, the tuning fork is placed adjacent to the ear canal (air conduction). In the presence of normal hearing or sensorineural hearing loss, air conduction is better than bone conduction. Your child may be especially uncomfortable lying down, so he might have a hard time sleeping.
Audiograms objectively measure hearing levels and compare them with standards adopted by the American National Standards Institute in 1969.1 Normal hearing levels are 20 dB or better across all frequencies. The audiogram measures air conduction and bone conduction and presents them graphically across the hearing frequencies.
Babies may push their bottles away because pressure in their ears makes it hurt to swallow. Audiographically demonstrated conductive hearing loss results in the air line falling below the bone line, creating an air-bone gap.Speech testing should be performed using standard word lists. Home Care for Ear InfectionsWhile the immune system fights the infection, there are things you can do to fight your child’s pain. The speech reception threshold is the sound level at which 50 percent of presented words are understood.
The speech recognition score is the percentage of words understood at 40 dB above the speech reception threshold.Conductive Hearing LossEXTERNAL EARComplete occlusion of the ear canal by cerumen is a frequent cause of conductive hearing loss. Non-prescription painkillers and fever reducers, such as ibuprofen and acetaminophen, are also an option.
Warm water (body temperature) irrigation is a safe method of removing cerumen in patients who have no history of otitis media, perforation of the tympanic membrane, or otologic surgery.
Antibiotics for Ear InfectionsEar infections often go away on their own, so don’t be surprised if your doctor suggests a "wait and see" approach.
The distance to the tympanic membrane must be kept in mind, because otoscopes do not allow for depth perception. Aqueous-based preparations, including docusate sodium, sodium bicarbonate, and hydrogen peroxide, are effective cerumenolytics.2,3Foreign bodies in the external auditory canal also can cause unilateral conductive hearing loss. If the object is not impacted or hygrostatic, warm water irrigation probably should be attempted first. Complications of Ear infectionsIf your child’s ear infections keep coming back, they can scar his eardrums and lead to hearing loss, speech problems, or even meningitis.
If this approach is not effective, the foreign body can be removed with an instrument if the patient is cooperative. If the patient is uncooperative, removal in an operating room may be necessary.Otitis externa is an infection of the skin of the external auditory canal. Ear TubesFor stubborn ear infections that just won’t go away, doctors sometimes insert small tubes through the eardrums. Patients with otitis externa experience pain on manipulation of the pinna or tragus, and their ear canal is edematous and filled with infectious debris.
The most common pathogens in otitis externa are Pseudomonas aeruginosa and Staphylococcus aureus.4 Treatment involves debridement of the canal, followed by the application of ototopical drops.
In patients with severe otitis externa, a wick is placed in the ear for two to three days to ensure delivery of the medication.
Tonsils Can Be the CauseSometimes a child’s tonsils get so swollen that they put pressure on the Eustachian tubes connecting her middle ear to her throat -- which then causes infections.
Preventing Ear InfectionsThe biggest cause of middle ear infections is the common cold, so avoiding cold viruses is good for ears, too. The conductive hearing loss resolves after the inflammation subsides.Exostoses and osteomas are benign bony growths of the external auditory canal that interfere with normal cerumen migration, leading to occlusion and conductive hearing loss.
Other ways to prevent ear infections include keeping your child away from secondhand smoke, getting annual flu shots, and breastfeeding your baby for at least 6 months to boost her immune system.
Allergies and Ear InfectionsLike colds, allergies can also irritate the Eustachian tubes and contribute to middle ear infections.
Osteomas are single and unilateral, and are found at the bony-cartilaginous junction (Figure 2). If you can’t keep your child away from whatever’s bothering him, consider having him tested to identify the triggers. Sebaceous cysts, fibromas, papillomas, adenomas, sarcomas, carcinomas, and melanomas also have been reported.
If a malignancy is suspected, prompt biopsy is indicated.MIDDLE EARMiddle ear pathology may lead to conductive hearing loss.


Perforations of the tympanic membrane cause hearing loss by reducing the surface area available for sound transmission to the ossicular chain (Figure 3). In patients who have had chronic otitis media with tympanic membrane perforation, otoscopic examination and debridement are essential.
Ototopical antibiotics (ofloxacin [Floxin]) are necessary, and oral antibiotics may be helpful.
Small perforations (less than 2 mm) often heal spontaneously.5 In the acute setting, blood may obstruct the ear canal and prevent visualization of the membrane. If the perforation or hearing loss persists beyond two months, the patient should be referred for consideration of surgical correction. The diagnosis of otitis media can be confirmed by tympanometry and audiometry, and resolution of the effusion restores hearing. Congenital cholesteatoma presents as a pearly white mass located behind an intact tympanic membrane in a patient with unilateral conductive hearing loss. Acquired cholesteatoma results from a retracted or perforated tympanic membrane with an ingrowth of epithelium. Conductive hearing loss caused by ossicular erosion is present in 90 percent of patients with cholesteatomas.8 Longstanding cholesteatomas expand to involve the mastoid, inner ear, and facial nerve. Suspicion of cholesteatoma warrants surgical consultation.Myringosclerosis of the tympanic membrane develops in response to infection or inflammation (Figure 3). Irregular white patches consisting of calcium are visible on the membrane.9 Isolated myringosclerosis of the tympanic membrane rarely causes significant conductive hearing loss.
However, extensive myringosclerosis, referred to as tympanosclerosis, involves the tympanic membrane, ossicular chain, and middle ear mucosa, and causes significant conductive hearing loss by stiffening the entire system.Otosclerosis is characterized by abnormal bone deposition at the footplate (base of stapes).
This bone deposition leads to fixation of the stapes at the oval window, preventing normal vibration. Otosclerosis typically presents as progressive bilateral conductive hearing loss in middle-aged white women.
It is the leading cause of conductive hearing loss in adults who do not have a middle ear effusion or a history of otitis media.10 There is usually a positive family history. These neuroendocrine tumors arise from the adventitia of the jugular bulb or the neural plexus within the middle ear space. Characteristically, patients presenting with glomus tumors are women 40 to 50 years of age who report pulsatile tinnitus and hearing loss. On examination, a pulsating reddish-blue mass may be seen behind an intact tympanic membrane. However, diagnosis of these tumors is difficult, and computed tomography of the temporal bones is required. Although most patients with this type of hearing loss are adults, children also can be affected. Hereditary and non-hereditary congenital hearing loss are the two major pediatric classifications. The majority of hereditary losses are autosomal recessive and are frequently associated with other systemic findings.
More than 100 congenital syndromes are associated with sensorineural hearing loss.The consequences of delayed detection can be significant. Neonates considered at high risk for congenital hearing loss (Table 3)11 traditionally have been screened, and 30 states now require universal newborn auditory screening.12 The American Academy of Pediatrics and several other organizations endorse universal auditory screening. Year 2000 position statement: principles and guidelines for early hearing detection and intervention programs.
The etiology is a combination of inherited and environmental factors, including lifetime noise exposure and tobacco use.
High frequencies are affected first, typically at 4,000 Hz, followed by middle and lower frequencies.
The use of foam-insert earplugs decreases noise exposure by 30 dB.A less common cause of hearing loss is ototoxin exposure, typically from diuretics, salicylates, aminoglycosides, and many chemotheraupetic agents.
These medications must be administered carefully in patients who are elderly, have poor renal function, require a prolonged course of medication, or require simultaneous administration of multiple ototoxic agents. Patients with ototoxin exposure may experience hearing loss or dizziness.Autoimmune hearing loss has been diagnosed with increasing frequency since the 1980s. Patients present with rapidly progressive bilateral sensorineural hearing loss and poor speech discrimination scores, and they also may have vertigo or disequilibrium.
Hearing loss progresses over three to four months, and an associated autoimmune disorder may be present. Symptoms usually improve with the administration of oral prednisone, and response to this steroid is currently the best way to make the diagnosis. Low-dose methotrexate therapy is becoming an accepted alternative to long-term prednisone therapy.14UNILATERAL HEARING LOSSTemporal bone fractures can cause unilateral sensorineural and conductive hearing loss.
When the fracture line involves the bony labyrinth (cochlea or vestibule), sensorineural hearing loss occurs. Temporal bone injuries are associated with facial nerve paralysis, cerebrospinal fluid leakage, and other intracranial injuries. Early consultation is essential, and prompt surgical intervention may be required.Trauma may cause rupture of the round or oval window membranes, with perilymph leaking into the middle ear (fistula).
Perilymph fistulas also may occur after straining, lifting, coughing, or sneezing, and are managed with three to six weeks of bed rest, followed by surgical repair if symptoms do not improve.15Meniere's disease is another cause of sensorineural hearing loss.
Patients report unilateral fluctuating hearing loss with aural fullness, tinnitus, and episodic vertigo. Initially, the hearing loss is in the low frequencies, but higher frequencies are affected as the disease progresses.
The etiology of Meniere's disease remains unclear, but endolymphatic hydrops (increased fluid pressure within the inner ear) has been identified.
The work-up consists of serial audiometry to document a fluctuating loss, vestibular testing to verify the diseased ear, and radiographic imaging to rule out an acoustic tumor.
Hearing aids are often ineffective because patients suffer from poor speech discrimination, as well as diminished tolerance to amplified sound. A history of upper respiratory infection within a month of the hearing loss is often described in patients who have a viral etiology. The work-up includes audiometry, followed by radiographic imaging to rule out an acoustic tumor. One study found that patients with minimal hearing loss, no vestibular symptoms, and early treatment have better outcomes.18Patients with acoustic neuromas present with unilateral sensorineural hearing loss approximately 10 to 22 percent of the time19 (Figure 6).
Patients with asymmetric sensorineural hearing loss require evaluation for a retrocochlear tumor.
