The red blood cells circulate through the body carrying oxygen and nutrients to feed the cells. Diagnosis of this hearing loss type may involve a CT scan, MRI, and EEG (electroencephalogram) which measures electrical activity in the brain. Congenital defects in the outer or middle ear – defect and damage to the outer or middle ear.
Sensorineural hearing loss is caused due to damage or disease of the inner ear or auditory nerve. Birth Asphyxia (lack of oxygen supply to the new born due to inability to breathe normally resulting in blueness of baby due to various reasons). Central hearing loss is due to a damage, malformation or infections of the neural pathways and the hearing centres in the brain. Functional hearing loss is due to some psychogenic condition or maybe due to deliberate exaggeration of hearing thresholds for personal gains. Nasopharyngeal or "nose" cancer (NPC) arises from the nasopharynx, a small anatomic space located directly behind the nasal cavity. Risk factors for NPC include Ebstein Barr Virus (EBV) infection and excessive salted fish consumption.
The large majority of NPCs consist of poorly differentiated or undifferentiated carcinoma (descriptive terms for the appearance of the cancer under the microscope). NPC is distinct from other squamous cancers of the upper aero-digestive tract in its epidemiology, biology, clinical behavior, and treatment.
Patients suspected of, or at risk of developing NPC should have a blood assessment for EBV antibodies, a fibreoptic nasoendoscopy and tissue biopsies for diagnosis. The primary treatment for NPC is external beam radiation therapy, usually given in combination with chemotherapy. Surgery is usually only considered for patients with recurrent disease (cancer that relapses after the completion of primary radiation and chemotherapy.
The 5-year cure rates for Stages I & II NPC are 90 a€“ 98%, and for Stage III & IV, 60 a€“ 75%. Unlike SCC, recurrent NPC, if detected early is very treatable, and can result in good long-term survival.

The present report describes clinical, radiographic, and pathological features of an external auditory canal giant apocrine hidrocystoma in a 36-year-old Iranian woman. Apocrine hidrocystoma is generally regarded as a benign apocrine tumor which is mostly solitary.

A 36-year-old woman presented with oneyear history of fullness and hearing loss in the left ear and felt a mass in the ear canal when it was touched for cleansing. Hearing loss is due to many possible causes and can be divided into two basic conductive and sensorineural types. Hearing loss subsequent to the obstruction of external auditory canal by a tumor is unusual.
This may be due to improper development, damage or disease to any part of the hearing mechanism.
It could also result as an after effect of infectious diseases like measles, mumps, meningitis and T.B.
One of the main causes of this type of loss is the long standing ear infection known as Chronic Suppurative Otitis Media (CSOM).
The degree of hearing impairment (in dBHL) as given in column 3 below is calculated by averaging the hearing thresholds at 500 Hz, 1 khz & 2 khz obtained from pure tone audiometry. There is a strong genetic predispostion for NPC, and it is seen with highest frequency in Chinese males of Cantonese descent originating from the Quangdong province in Southern China. CT, MRI and often PET scans are required for accurate staging of the disease, and for treatment planning. On otoscopy, a huge cystic mass was found in the external auditory canal (EAC) without any evidence of inflammation or redness. Conductive hearing loss is caused by anything that interferes with the transmission of sound from the outer to the inner ear.
Apocrine hidrocystoma, a benign skin appendage tumor, is usually asymptomatic and occurs as a solitary translucent nodule of cystic consistency. Additionally, anemia is characteried by low RBC (red blood cell) count, which also presents a reduced amount of oxygen to the body cells.
It has a microphone for sound waves, an amplifier to increase sound, and a speaker that transmits to the ear. Deafness at birth or in early childhood has disastrous effects on the child's overall development. Some of the children classified as learning disabled or slow learners may have this type of hearing loss. Deafness at birth or in early childhood has disastrous effects on the child’s overall development.
It completely obstructed the canal and prevented the visualization of the tympanic membrane. The usual location of this lesion is on the face especially medial canthus, but it is occasionally seen on scalp, chest or shoulders.1,3 The ear and external auditory canal are unusual locations.

Couple these with a reduced circulation and you have a situation ripe for reduced oxygenation and circulation to the auditory system resulting in hearing loss. Then it travels to the middle ear, the inner ear to the cochlea, then to the brain where the sound is produced. These effects vary depending upon the age of onset, nature and degree of hearing impairment. This starts with conductive loss yielding to sensorineural impairment, if not treated immediately and regularly. When touched, the mass, which was attached to the wall of canal, appeared compressible and cystic and measured about 23 mm in diameter. An audiologist will help you in choosing the right hearing aid for your needs.Cochlear implant is a surgically implanted hearing device that is comprised of the internal and external parts.
In histopathology, the dermis contains one or several large cystic spaces with some papillary projections, that are lined by rows of cuboidal to columnar-shaped secretary cells The nuclei of these cells are positioned basally.2 The outer layer of cells composing the cyst wall is formed by myoepithelial cells in which the long axes run parallel to the cyst wall.
The internal part is inserted beneath the skin behind the ear in the temporal bone, that functions to stimulate the auditory nerve. The secretary cells contain periodic-acid-Schiff positive, diastase-resistant granules and occasionally contain pigment granules, which provide the brown color of the cystic fluid. The external part is worn behind the ear, same as a behind the ear hearing aid, and transmits vibrations to the implanted piece. The sound is not like what is normally heard and will take some time to get accustomed to it. The lesion was approached under general anesthesia, through a post- auricular incision and a cystic mass was completely removed along with adhering skin of the canal.
The skin graft prepared from post-auricular region was placed into the EAC and supported by gel foam.
The cyst was lined with cuboidal, eosinophilic cells that demonstrated decapitation secretion (Fig.
Therefore, a diagnosis of giant apocrine hidrocystoma was made based on these findings and size of the mass. After healing process, audiometry showed the return of hearing to normal limit, without any evidence of recurrence during one-year follow-up.
