Congenital malformations, deformities, and chromosomal abnormalities (Q00-Q99). Genetically determined forms of hearing loss. Auditory canal stenosis (narrowing)/atresia of the auditory canal (nonunion of the auditory canal). Malformations of the ear, unspecified Osteogenesis imperfecta (OI) – genetic diseases with autosomal dominant inheritance, more rarely autosomal recessive inheritance; 7 types of osteogenesis imperfecta are differentiated; the main … Otosclerosis: Or something else? Differential Diagnosis

Otosclerosis: Examination

A comprehensive clinical examination is the basis for selecting further diagnostic steps: General physical examination – including blood pressure, pulse, body weight, height. ENT medical examination – including inspection of the external ear and auditory canal. Otoscopy (ear examination): usually unremarkable, if necessary, the active reddish otosclerosis focus (as a so-called Schwartz sign; hyperemia (increased … Otosclerosis: Examination

Otosclerosis: Diagnostic Tests

Obligatory medical device diagnostics. Otoscopy(ear examination) [usually unremarkable, may be able to detect through the tympanic membranethe active reddish focus of otosclerosis (as a so-called Schwartz sign; hyperemia (increased blood flow) of the promontory (anatomical structure in the tympanic cavity of the middle ear)]. Tone audiometry – testing of hearing with the measurement of volumes … Otosclerosis: Diagnostic Tests

Otosclerosis: Surgical Therapy

1st order Staple surgery: Partial or complete surgical removal of the stapes: Stapedotomy (partial stapes removal) [gold standard]. Stapedectomy (stapes removal). Stapes replacement prostheses Note: Hearing improvement sought through surgery cannot be guaranteed to the patient preoperatively! Possible complications of stapesplasty Complete deafness (due to surgical work on the entry port to the inner ear!). … Otosclerosis: Surgical Therapy

Otosclerosis: Symptoms, Complaints, Signs

The following symptoms and complaints may indicate otosclerosis: Leading symptoms Gradual onset of conductive hearing loss in the low frequencies; hearing is better in noisy environments than at rest; onset usually unilateral Tinnitus (ringing in the ears) If necessary, sensorineural hearing loss If applicable, vertigo (dizziness) Note: The disease can affect one or both ears … Otosclerosis: Symptoms, Complaints, Signs

Otosclerosis: Causes

Pathogenesis (development of disease) The cause of otosclerosis has not been conclusively determined. The disease runs in families. Otosclerosis results in bone remodeling processes at the ossicles with fixation of the stapes at the oval window. The result is a conductive hearing loss (middle ear hearing loss). If the otosclerosis affects the cochlea (snail), a … Otosclerosis: Causes

Otosclerosis: Medical History

The medical history (history of the patient) represents an important component in the diagnosis of otosclerosis. Family history What is the general health of your family members? Are there any diseases in your family that are common? Are there any hereditary diseases in your family? Social history What is your profession? Is there any evidence … Otosclerosis: Medical History
