Diagnosis and Treatment of Thyroid Problems
Thyroid nodules are very common findings on ultrasound. There are clear protocols on when these nodules should be analyzed and / or removed. In addition, thyroid surgery should always be carried out by expert surgeons in the area who perform this surgery regularly to avoid possible complications. At the Head and Neck Clinical Center we can advise you, and if necessary, perform ultrasound-guided biopsies.
Imaging Diagnosis, Head and Neck Ultrasound
As experts in the head and neck area, we will indicate imaging studies when these are indicated. We also have ultrasound equipment to carry out diagnoses and follow-up of injuries.
Taking Biopsies
Depending on the characteristics and location of the lesion, it is possible to perform biopsies with local anesthetic or with general anesthesia. Occasionally, fine needle aspiration (FAB) biopsies may be sufficient. We have all the necessary equipment to take the biopsy and analyze the results.
Prick Test
Skin test widely used in otorhinolaryngology for the study of allergies. It is used to check what substances you are allergic to. A drop of the substance to be tested is deposited on the skin and after 15-20 minutes it is evaluated if the answer is positive.
Audiometry
Study that allows determining how a patient listens, by placing headphones and presenting different frequencies. It is an easy study to perform and frequently used to determine if there is loss in hearing.
Tympanometry
Study that allows to measure and graph the pressure in the middle ear (measures how much the tympanic membrane and ossicles move) to determine if there is fluid or mucus accumulated behind the eardrum or if the Eustachian tube (which normally ventilates the middle ear ) works properly.
Otomicroscopy
Visualization of the tympanic membrane through a microscope that allows an amplified vision in order to be able to observe the eardrum more clearly. By means of otomicroscopy, different types of ear diseases can be diagnosed such as earwax plugs, cholesteatoma, tympanic perforations, secretory otitis media.
Auditory brainstem response (ABR)
Study that allows, by placing patches (electrodes) on the head, to determine how the auditory nerve reacts to sound.
Otoacoustic Emissions (OAE)
Study in which microphones are placed in the ears that detect the sound emitted by the cochlea. The absence of these sounds is suggestive of deafness.
Flexible Nasolaryngoscopy
Painless study performed by means of a special flexible camera to evaluate structures of the nose (septum, turbinates), adenoids, linear tonsils, base of tongue and larynx (vocal cords).
Laryngostroboscopy
A painless study performed using a specialized flexible camera that takes slow-motion shots of the vocal cords. The objective is to observe the movement of the vocal cords on a monitor to establish if there is any pathology that is disrupting the normal functioning of the vocal cords.
Voice Analysis
Series of studies carried out by an expert that provides information on the acoustics of the voice through studies of the components of the voice: fundamental frequency, intensity, jitter, shimer, etc.
Functional Swallowing Test Under Endoscopic Vision
Dynamic swallowing study performed with the flexible fibrolaryngoscope, which evaluates the different phases of swallowing in real time with different types of food.
Videonystagmography
A series of tests is performed in patients with vertigo (illusory sensation of movement) to study the eye movements responsible for keeping the images perceived by the retina stable. The technique makes it possible to identify the presence of abnormal spontaneous eye movements, eye movements caused by stimuli from the organ of balance and to compare the results of both organs of balance.
V-HIT or head impulse test
Study used in patients with vertigo that allows to evaluate by means of a high speed video camera, compensatory eye movement when moving the head rapidly. This study allows to quantify the relation of movement of the head with the eyes and can also record abnormal eye movements that occur in patients with vestibular injuries.
VEMPS or myogenic vestibular evoked potentials
Study used in patients with vertigo to evaluate the organ of balance, comparing one side with the contralateral by means of special sensors that measure the vestibulo-colic reflex (relationship between the organ of balance and the neck muscles).
Digital posturography
Study that assesses the imbalance in a quantitative and objective way, measuring body oscillations on a specialized platform.
Caloric tests
Study used in patients with vertigo, thermally stimulating the labyrinth of each ear by irrigating the external auditory canal with air at 30ºC and 44ºC. Then the nystagmus (spontaneous abnormal eye movement) that this stimulus generates in each eye is comparatively evaluated. Computerized dynamic visual acuity test according to the AIBd: test that evaluates the presence of oscillopsia with head movement in the horizontal and vertical planes.
Polysomnography
Sleep study carried out through various sensors that helps determine how many apneas (complete cessation of breathing) you have during the night. It is used for the diagnosis of obstructive sleep apnea.
Therapeutic trial with CPAP
The medical treatment for sleep apnea is with CPAP. This is a device that, through positive pressure, delivers oxygen through a naso-buccal or nasal mask. The therapeutic test is used to determine if the patient is comfortable with the treatment and if not, other options are offered.
