The simplest type of hearing test is the whispered voice test. The doctor whispers words or numbers at different distances from your ear and asks you to repeat them. It is a quick, easy way to find out whether you can hear normally, but more specific tests are needed if there is any doubt.
In pure-tone audiometry, sound is played to one ear at a time through headphones. You are asked to press a button each time you hear a sound. The volume and pitch of the sound are varied to find the quietest sounds that each ear can hear at different pitches.
In bone-conduction audiometry, the sound comes through a tight headband resting behind the ears and is heard by conduction through the bones of the skull. This reveals how well the inner ear is working.
Audiometry takes about 15 minutes. You will not feel any discomfort and there are no side effects. Tympanometry measures how well the eardrum moves (fluid in the middle ear may stop the eardrum vibrating). A probe seals the ear canal and measures the pressure changes in the canal in response to a loud noise that lasts a few seconds. It is not uncomfortable.
Other hearing tests may be used in special situations. Békésy audiometry is used in industry, and distraction testing or play audiometry is used to test young children or people with learning difficulties.
Nasal endoscopy is a medical procedure performed by an Otolaryngologist (ENT specialist) in the doctor's clinic. Prior to the procedure, an analgesic together with a topical nasal vasoconstrictor is sprayed into both nostrils.
The purpose of this is to ensure a painless procedure. The vasoconstrictor is applied for shrinking the mucosal lining in the nose so that the endoscope can be manoeuvred easily through the nasal passages.
The endoscope is a rigid tube with a light attached at the tip together with a tiny camera for capturing images of the nasopharynx.
As the patient is awake, he can actually see the insides of the nasal passages as the endoscope is inserted into the nostrils through live video.The endoscope is attached to an equipment which is connected to a CRT monitor for the patient to follow the procedure and for the doctor to explain the findings.
To examine the nasopharynx, the nasal endoscope is inserted into the nostrils and navigated by the specialist to the various openings of the sinus cavities. For accurate diagnosis of sinus infection, nasal endoscopy is commonly used today. It can provide very clear information about the severity of the sinus infection so that the correct treatment options are applied for a complete cure. At the same time, nasal endoscopy allows for detection of abnormal growths such as nasal polyps and tumors.
The advantage of nasal endoscopy over that of a CT scan is its ability to show clearly to the doctor the state of the physical tissues and structures within the nose. Also, the patient is not exposed to any form of radiation that comes with a CT scan or an MRI.
Throat Endoscopy is a medical procedure performed by an ENT Surgeon in OPD itself. Prior to the procedure an anolgeric is sprayed in patient's throat. The purpose of this is to ensure a painless procedure and to curb the gag reflex.
Diffrerent angled endoscope are used to visualize the structure of oral cavity, pharynx and larynx. Commonly 70° and 90° endoscopes are used. Throat endoscopy helps to detect any abnormality in pharynx and larynx. It also helps to detect the mobility of vocal cords and any lesion in vocal cords.
Speech Therapy provides the evaluation, diagnosis, and treatment of communication disorders (speech disorders and language disorders), cognitive-communication disorders, voice disorders, and swallowing disorders.
A common misconception is that Speech Therapy is restricted to adjusting a speaker's speech sound articulation to meet the expected normal pronunciation, such as helping English speaking individuals enunciate the traditionally difficult "r" pronunciation.
Speech Therapy can also often help people who stutter to speak more fluently. Articulation and fluency are only two facets of the work of an Speech Therapy, however. In fact, Speech Therapy is concerned with a broad scope of speech, language, swallowing, and voice issues involved in communication, like: Receptive and expressive language disorders, speech sound disorders, childhood apraxia of speech (CAS), stuttering, and language-based learning disabilities
