Otosclerosis
Otosclerosis is a primary metabolic bone disease that causes fixation of the ossicles, resulting in conductive or mixed hearing loss. It is genetically mediated and more common in women. The incidence increases with age, most commonly occurring between 15-45 years old. Normal bone in the otic capsule is replaced with highly vascular spongy bone that immobilizes the stapes footplate, disrupting vibration conduction and causing hearing loss. Symptoms include slowly progressive, often asymmetric conductive hearing loss and tinnitus. Diagnosis involves audiometric testing demonstrating the conductive nature of the loss. Treatments range from hearing aids to surgical procedures like stapedectomy or stapedotomy that aim to restore vibration conduction.
Otosclerosis(sbo 3)
Otosclerosis is a hereditary disorder affecting the bone of the inner ear that causes abnormal bone resorption and formation. It commonly affects the stapes bone, causing conductive hearing loss. Histologically, it presents as areas of bone resorption, new bone growth, and connective tissue. Clinically, it presents when the stapes or surrounding joints are involved, causing conductive hearing impairment. Rarely, it can progress to the inner ear and cause sensorineural hearing loss. Surgical intervention like stapedectomy is usually successful in restoring hearing by replacing the fixed stapes footplate with a prosthesis. Postoperative risks include further hearing loss, dizziness, and facial nerve injury, but successful surgery typically
External ear abnormalities
Abnormalities of the external ear can involve the pinna or auricle and the external ear canal. Congenital abnormalities of the pinna include anomalies such as microtia, cryptotia, and preauricular tags or sinuses. The pinna can also be affected by traumatic injuries, inflammatory disorders like perichondritis, and tumors. Abnormalities of the external ear canal include congenital conditions like atresia, traumatic injuries, inflammatory conditions like otitis externa, and tumors. Both areas can be involved by a variety of acquired and developmental issues that may require surgical or medical treatment.

Otosclerosis dr.p.kartyhikeyan,07.03.2016
This document provides an overview of otosclerosis, including its definition, etiology, types, clinical features, diagnosis, and treatment options. Otosclerosis is a primary disease of the otic capsule that causes conductive hearing loss by fixing the stapes footplate. It has an unknown etiology but may be hereditary or related to hormonal or enzymatic factors. Types include stapedial, cochlear, and malignant otosclerosis. Clinical features are conductive hearing loss and tinnitus. Diagnosis involves audiometric testing. Treatment options include sodium fluoride medication or stapedectomy surgery to improve hearing.
Ear trauma
Ear trauma can occur from a variety of causes including loud noises, explosions, burns, and physical impacts. External ear trauma commonly results in bruising or lacerations to the auricle or pinna. Impacts can deform the ear over time into a "cauliflower" shape if not treated. Foreign objects in the ear should be removed carefully to avoid further injury. Thermal burns produce swelling and pain. Changes in pressure like from diving can rupture blood vessels in the middle ear. Head injuries sometimes fracture the skull and temporal bone, risking damage to the middle ear structures, hearing loss, and facial nerve involvement.

Medical Imaging, Otitis Media, & Otosclerosis
This document discusses medical diagnostics used to evaluate ear conditions like otitis media and otosclerosis. It describes imaging tests like CT scans and MRIs that are useful for visualizing bony and soft tissues of the ear. Otitis media is an inflammation of the middle ear that is usually caused by bacteria and often accompanies respiratory infections. It is more common in young children and can be treated with antibiotics or tubes. Left untreated, it can lead to permanent hearing loss or other complications. Otosclerosis occurs when excessive bone growth fixates the stapes, resulting in a conductive hearing loss. It is often treated surgically by removing the stapes and placing a prosthesis.
Otosclerosis
Otosclerosis is a hereditary disorder characterized by abnormal bone growth in the middle ear that immobilizes the stapes bone and disrupts sound transmission, resulting in conductive hearing loss. It typically onset between ages 15-35 and may be exacerbated by pregnancy. Diagnosis involves hearing tests showing better bone than air conduction, otoscopy revealing a pinkish-orange discoloration, and audiometry showing a hearing threshold of 60 dB. Treatment options include hearing aids or surgery such as stapedectomy or stapedotomy to remove the stapes bone and insert a prosthesis to restore hearing.
Keratosis obturans
This document discusses keratosis obturans, which is the accumulation of desquamated keratin in the external auditory meatus. It can occur in two types - silent and inflammatory. The silent type is not associated with infection, while the inflammatory type is caused by acute ear canal inflammation. Clinically, it presents as a white keratin plug occluding the ear canal, sometimes with accompanying granulations or bone erosion. Treatment involves using keratolytic agents to break down the plug, or surgical removal under general anesthesia, with canal plasty for recurrent cases or mastoidectomy if associated with primary cholesteatoma of the external canal.

Brain anatomy in concerin of diagnostic imaging
The document discusses the anatomy and structures of the brain. It describes the layers of grey matter in the cerebral cortex, white matter containing bundles of axons, and the limbic system, hypothalamus, and pituitary gland. It also outlines the ventricular system containing cerebrospinal fluid, the cerebellum and brainstem, cerebral vasculature, and techniques for imaging the brain including CT and MRI.
Soft tissue tumours
Soft tissue tumors can be identified on radiography. Masses in the hands and feet are more likely to be benign, while those in the thigh, calf and arm indicate a higher likelihood of malignancy. Radiography can detect fat-containing masses, foreign bodies like glass and metal, and mineralization which occurs in 17% of soft tissue tumors and is a hallmark of venous malformations. Calcification patterns can also provide clues about tumor type.
Wrist Joint

Brain infection
Brain infections can occur from bacteria, viruses, fungi or parasites. Common causes include tuberculosis (TB), neurosyphilis, fungal infections like aspergillus, or unknown causes leading to brain abscesses. Diagnostic imaging plays an important role in identifying the location and characteristics of infectious lesions in the brain to determine the underlying condition and guide treatment.
Sinuses & neck lesions
This document discusses several conditions affecting the sinuses, neck, and related areas. It covers glomus tumor, glomus jugular tumor, mucococele, osteoma, juvenile angiofibroma, squamous cell carcinoma, lesions of the para pharyngeal spaces and nasopharynx, quinsy abscess, adenoid cystic carcinoma of the larynx, and lesions of the thyroid gland and mandible bone.
Salviary glands
The salivary glands produce saliva, which is essential for the digestion of food and the maintenance of good oral health. There are three major pairs of salivary glands - the parotid glands located near the ears, the submandibular glands under the jaw bone, and the sublingual glands under the tongue. Together the salivary glands secrete saliva through ducts inside the mouth.
Spine degenerative disease
The spine is made up of vertebrae separated by intervertebral discs that allow movement and provide shock absorption. Diagnostic imaging plays an important role in evaluating the spine for conditions like fractures, disc herniations, spinal stenosis, and tumors. Imaging modalities like X-rays, CT scans, MRI, and bone scans can detect abnormalities and aid physicians in diagnosing and treating various spinal disorders.
Congenital lesions and variants of renal system
This document lists and numbers various congenital lesions and variants that can occur in the renal system, including fetal lobulation, renal pseudotumors, renal agenesis, renal dysplasia, renal hypoplasia, supernumerary kidney, rotation abnormalities, renal ectopia, horseshoe kidney, crossed fused ectopia, renal vascular abnormalities, duplication abnormalities, ureterocele, ureteric diverticulum, multicystic kidney, polycystic kidney, ARPCD, tuberous sclerosis, medullary cystic disease, medullary sponge kidney, calyceal diverticulum, PUJ obstruction, retrocaval ureter, primary mega ureter, and
Von hippel –lindau disease
Von Hippel-Lindau disease is an autosomal dominant neurocutaneous disorder characterized by a high incidence of cysts in multiple organs and tumor development. Common manifestations include renal cell carcinoma in 25-40% of cases, cerebellar hemangioblastoma, retinal angioma, pancreatic cysts and tumors, and pheochromocytoma. Imaging findings include lesions that are intermediate to high signal on MRI and variably enhancing on CT and IVU.
Urethra lesions
Urethral strictures can be traumatic, inflammatory, or neoplastic in nature. Inflammatory strictures are usually located in the proximal bulbar urethra and are caused by infections like gonorrhea or chlamydia. Traumatic strictures occur after catheterization or surgery and are commonly found in the posterior urethra. Both inflammatory and traumatic strictures can be multiple, vary in length, and lead to complications such as fistulas or pseudodiverticula if left untreated.
