Tympanometry

Tympanometry is a non-invasive diagnostic procedure used to assess the function of the middle ear.
It measures the mobility of the tympanic membrane (eardrum) and the pressure in the middle ear space.
Tympanometry is commonly used to detect middle ear disorders, such as otitis media, tympanic membrane perforations, or Eustachian tube dysfunction.
The test involves placing a small probe into the ear canal, which seals the canal and applies varying air pressure to the eardrum.
The resulting tympanogram, a graph of the eardrum's movement, can provide valuable information about the condition of the middle ear.
Tympanometry is an important tool in the evaluation and management of hearing-related conditions, and it is widely used in both clinical practice and research settings.

The Italian version SF-36 14 (link) includes 36 items divided
into 8 scales: Physical Functioning (10 questions),
Physical Role (4 questions), Body Pain (2 questions),
General Health (5 questions), Vitality (4 questions), Social
Functioning (2 questions), Emotional Role (4 questions)
and Mental Health (5 questions). The 8 scales
were scored individually and then combined, resulting
in a scale ranging from 0 to 100; the highest score indicates
the best health while the lowest score denotes
poor health.
The study was approved by the Ethics Committee of the
"G.B. Grassi" Hospital of Rome (Protocol no. 60037). All
patients signed the specific informed consent forms.
Patients suffering from acute dizziness from 1 day to 30
days were recruited in the operative unit of ENT "G.B.
Grassi" Hospital of Rome between July 2009 and February
2010. Patients included in the study suffered from
at least one of the following vestibular disorders: benign
paroxysmal positional vertigo (BPPV), vestibular neuritis
and uncompensated vestibular hypo-function; exclusion
criteria were dizziness due to cardio-vascular disease and
neurological disease.
After a careful and detailed anamnesis, all patients underwent
pure-tone audiometry, tympanometry, Dix-
Hallpike manoeuvre, McClure manoeuvre, Head Shaking
Test (HST), caloric labyrinth stimulation according
to the Fitzgerald-Hallpike method and Vestibular Evoked
Myogenic Potential (VEMP). The patients with vestibular
neuritis were treated with a therapeutic protocol with
beclomethasone i.m. (intramuscularly), 4 mg twice a day
for 8 days, and Vanciclovir, 400 mg twice a day, for 20
days. Our patients self-administered the DHI-I and Italian
SF-36, followed by a neurological and psychological
evaluation.

Various audiological testing methods were used to assess hearing dependent upon the patient’s age, cognitive and developmental abilities, and level of cooperation. Tympanometry was reviewed to determine the integrity of the conductive mechanism at the time of testing. Pure-tone air conduction thresholds were evaluated at frequencies 0.25, 0.5, 1, 2, 3, 4, 6, and 8 kHz in decibel (dB) hearing level (HL). Pure tone bone conduction thresholds were assessed at frequencies 0.25, 0.5, 1, 2, 3, and 4 kHz to determine the nature of the hearing impairment (i.e., conductive, sensorineural, or mixed). Click and tone-burst auditory brainstem response (ABR), auditory steady-state response, and/or distortion-product otoacoustic emissions (DPOAE) measurements were evaluated on patients who were unable to participate in conventional audiometric testing due to young age, cognitive or developmental delay, or lack of cooperation. The ototoxicity monitoring schedule consisted of an evaluation at the following time points: baseline (occurred within 2 weeks of initiation of radiation therapy), prior to each high dose cisplatin chemotherapy cycle, and at 9, 12, 15, and 24 months following diagnosis. Audiometric data from St. Jude and the nine collaborative sites were reviewed and assigned an ototoxicity grade by a single research audiologist at St. Jude (JKB). Each audiological evaluation was given an ototoxicity grade based on the Chang Ototoxicity Grading Scale [20 (link)] and the International Society of Pediatric Oncology Ototoxicity Scale (Table I) [1 (link)]. The latest audiometric evaluation that occurred between 5.5–24 months from on-treatment date was used for the analysis.

Of the 3,853 participants selected for audiometric testing, a subset was excluded as they had incomplete auditory data and/or missing dietary data (540 excluded). Additional exclusions were applied based on present ear tubes, abnormal otoscopy, impacted cerumen, abnormal tympanometry (peak pressure ≤ −150 daPa; compliance ≤ 0.3 ml), and/or more than 10-dB difference between test and retest thresholds at 1 kHz (635 excluded). Finally, LFPTA (0.5, 1, and 2 kHz) and HFPTA (3, 4, 6, and 8 kHz) were calculated for each ear. NHANES does not survey for congenital/genetic or sudden hearing loss; therefore, participants with LFPTAs or HFPTAs > 3 standard deviations (SD) above the mean for their age group (186 excluded), or > 15 dB difference between ears on either LFPTA or HFPTA (126 excluded), were excluded from further analysis. This left a final sample size of 2,366 participants available for inclusion in the reported analyses. Based on β-coefficients ≥ 0.80 for right vs left ear comparisons, the PTAs for right and left ears were averaged such that each subject contributed a single HFPTA and a single LFPTA to the analysis.

This study is a secondary analysis of data collected from January 2003 to March 2007 at the University of Texas Medical Branch, Galveston (UTMB) during a prospective, longitudinal study of naturally occurring URI associated with AOM6 (link). The primary purpose was to capture all URI episodes occurring during a one-year period in healthy young children at the peak age incidence of AOM to study the rate and characteristics of AOM following URI. The study was approved by the UTMB Institutional Review Board; written informed consent was obtained for all children. Healthy children were enrolled at 6 mos. to 3 yrs. of age; children with chronic medical problems or anatomical or physiological defects of the ear or nasopharynx were excluded. During the year, parents were asked to notify the study office as soon as the child began to have cold or URI symptoms (nasal congestion, rhinorrhea, cough, sore throat, or fever) or if they suspected that their child had ear infection. Children were seen by a study physician as soon as possible after URI onset and followed a few days later for OM complications; parents were compensated for time and travel. Study personnel also provided 2 home visits in weeks 2 and 3 of URI for tympanometry; no otoscopic examination was performed during the home visit.
In addition to parental self report of URI, the study personnel called the parents twice monthly to document any history of current URI symptoms and occurrence of any URI or AOM episodes missed since the last contact. An extensive review of medical records was performed at the completion of each child’s study. UTMB is the sole provider of pediatric healthcare in Galveston; diseases diagnosed and treated in our children are likely to be documented in our medical records. URI and AOM episodes not seen by the study group but captured from parent’s interviews or from medical records were recorded as “missed episodes”.

Traditional audiometry will be conducted in a soundproof booth by a trained audiologist. All participants will be examined bilaterally with otoscopy and tympanometry prior to testing to ensure normal middle ear functions. The tympanometry measurement will be carried out using the Madsen Zodiac Tympanometer (Natus, Taastrup, Denmark). Pure-tone air-conducted thresholds at octave (250–8000 Hz) and interoctave (3000 and 6000 Hz) frequencies will be examined as well as bone-conducted pure-tone thresholds at octave frequencies (250–4000 Hz) in both ears. During the examination, the audiologist will use pure-tone or alternatively warble tones in case of interfering tinnitus if it is deemed necessary for adequate threshold determination. The traditional audiometry session will also include a measure of speech intelligibility by measuring the word discrimination scores (DS) using the DANTALE I word lists. DS is the percentage of correctly repeated words. DANTALE consists of 8 word lists each containing 25 monosyllabic words.23 (link) Each participant will be presented with one list per ear at the most comfortable level (PTA+40 dB). The traditional audiometry will be carried out using a Madsen Astera2 audiometer (Natus, Taastrup, Denmark) connected with the DD65 v2 headphones (RADIOEAR, Minnesota, USA) and in accordance with ISO 8253-143 international standard for audiometric procedures.

Pure-tone audiometry was performed over the frequency range of 125–8,000 Hz for air-conduction (AC) and 250–4,000 Hz for bone-conduction (BC) in a soundproof room using standard clinical procedures, once normal status of tympanic membranes and external auditory meatus was ascertained on micro-otoscopic examination. Appropriate masking was used for BC testing and, when needed, for AC. The pure tone average (PTA) was calculated as the average of the BC thresholds of the four most impaired contiguous frequencies. Morphologies of audiometries were categorized as low-frequency, high-frequency or flat-type depending on the most affected tones. Audiometries were also classified according to the HL severity in four categories: “mild” (PTA ≤ 40 dB), “moderate” (PTA >40 and ≤ 70 dB), “severe” (PTA >70 and ≤ 90 dB) and “profound/anacusis” (PTA > 90 dB). In case of anacusis, PTA of 120 dB was assigned for statistical purposes. Standard tympanometry with a 226 Hz probe tone and ipsi/contralateral acoustic reflexes were administered to all patients. Speech audiometry with lists of disyllabic words was imparted on both ears to assess the words recognition score (WRS).

To determine the audibility of the stimuli presented during the CAEP sessions, aided behavioral hearing thresholds to the same stimuli were estimated using visual reinforcement audiometry (VRA; BSA, 2014 ). As VRA requires behavioral conditioning, it was performed several months after the CAEP sessions. Infants were aged between 7.4 and 21 months, with a mean age of 10.8 months. VRA was performed by two experienced pediatric audiologists who followed the British Society of Audiology recommended procedure as a guideline (BSA, 2014 ). During the VRA sessions, stimuli were presented at a rate of 4 Hz using the same set-up previously described for the aided CAEP sessions. Infants were first conditioned at a high test level with simultaneous presentation of a visual reinforcer. An adaptive procedure was then used to find threshold in 5 dB step sizes. One audiologist kept the child's quiet attention in the room, and the other controlled the sounds from the observation room, and judged when a response was present. Intermittent control trials and long gaps were included to judge for false responses, but the tester was not blind to these. At the VRA session, standard hearing aid checks, otoscopy examinations, and tympanometry examinations were again carried out. If hearing aid settings had changed since the CAEP sessions, the VRA was performed while wearing temporary hearing aids of the same model as used during the CAEP session and set to their previous settings. Hearing aid settings were also checked in a test box for consistency between the CAEP and VRA sessions. The decibel Sensation Level (dB SL) was estimated as CAEP presentation level minus the aided VRA-estimated behavioral threshold, both recorded in dB SpRefL in the sound field.

More about "Tympanometry"

Tympanometry is a non-invasive diagnostic procedure used to assess the function of the middle ear.
It measures the mobility of the tympanic membrane (eardrum) and the pressure in the middle ear space, providing valuable information about the condition of the middle ear.
This important tool is widely used in clinical practice and research settings to evaluate and manage hearing-related conditions, such as otitis media, tympanic membrane perforations, and Eustachian tube dysfunction.
The test involves placing a small probe into the ear canal, which seals the canal and applies varying air pressure to the eardrum.
The resulting tympanogram, a graph of the eardrum's movement, can help healthcare professionals diagnose and monitor various middle ear disorders.
Tympanometry is also commonly used with other audiometric tests, such as those conducted with the Titan, GSI Tympstar, AT235, HDA 200, TympStar, GSI 61, Unity PC audiometer, AT235 tympanometer, or AC40 audiometer, to provide a comprehensive assessment of a patient's hearing health.
In addition to its clinical applications, tympanometry is an important tool in hearing research, where it is used to study the mechanics and function of the middle ear.
The SAS software, for example, is often used to analyze tympanometric data in research settings.
By understanding the insights gained from tympanometry, researchers can advance our knowledge of hearing-related conditions and develop more effective treatments and interventions.
