Combine (Audiometry + Consultation) at Dr. Essa Lab
The Combine (Audiometry + Consultation) at Dr. Essa Lab is a comprehensive, non-invasive diagnostic service designed to evaluate an individual’s hearing acuity and provide immediate, expert clinical guidance. Hearing is a complex physiological process involving the outer ear, middle ear, inner ear, and the auditory pathways of the central nervous system. When sound waves enter the external auditory canal, they vibrate the tympanic membrane (eardrum). These vibrations are amplified by three tiny bones in the middle ear—the malleus, incus, and stapes—before reaching the cochlea in the inner ear. Within the cochlea, specialized sensory hair cells convert mechanical vibrations into electrical signals, which are transmitted via the vestibulocochlear nerve (Cranial Nerve VIII) to the auditory cortex of the brain for interpretation. Any disruption along this intricate pathway can lead to hearing impairment, communication difficulties, and reduced quality of life.
By combining pure-tone and speech audiometry with a professional clinical consultation, Dr. Essa Lab offers patients in Karachi and across Pakistan a seamless pathway from diagnosis to management. Audiometry serves as the gold standard for quantifying hearing thresholds across a range of frequencies, identifying whether a hearing loss is conductive, sensorineural, or mixed. The subsequent consultation bridges the gap between raw diagnostic data and clinical action. During this phase, an experienced healthcare professional interprets the resulting audiogram, correlates the findings with the patient’s medical history, performs a physical examination of the ear, and outlines a personalized treatment or rehabilitation plan. This integrated approach ensures that patients do not merely receive a graph of their hearing levels, but also gain a clear, actionable understanding of their auditory health and the next steps required to preserve or restore it.
Clinical Procedure: What to Expect
Patient Preparation
To ensure the utmost accuracy during your Combine (Audiometry + Consultation) at Dr. Essa Lab, proper preparation is essential. Please follow these clinical guidelines prior to your appointment:
- Avoid Loud Noise Exposure: Avoid exposure to loud environments—such as concerts, heavy machinery, personal audio devices at high volumes, or noisy industrial workspaces—for at least 12 to 24 hours before the test. This prevents temporary threshold shift (TTS), a temporary dulling of hearing that can skew test results.
- Ear Canal Inspection: Ensure your ears are free of excessive cerumen (earwax). If you suspect a significant wax buildup, consult a healthcare professional for safe removal prior to the test, as impacted cerumen can cause artificial conductive hearing loss. Do not use cotton swabs, as they can push wax deeper.
- Medical History Documentation: Bring a list of all current medications, especially known ototoxic drugs (such as high-dose aspirin, loop diuretics, certain antibiotics, or chemotherapy agents), as well as records of any previous hearing tests or ear surgeries.
- Symptom Log: Note any fluctuating symptoms such as tinnitus (ringing in the ears), vertigo (dizziness), a feeling of fullness in the ears, or recent viral infections, and share these with the clinician.
- No Fasting Required: There are no dietary restrictions for this test. You may eat, drink, and take your routine, non-ototoxic medications as prescribed.
During the Procedure
The Combine (Audiometry + Consultation) is a painless, highly structured evaluation that typically takes between 30 to 45 minutes to complete. The procedure is conducted in a quiet, controlled clinical environment to ensure precise measurements:
- Otoscopic Examination: The clinician begins by performing a visual inspection of your external auditory canal and tympanic membrane using an otoscope. This checks for physical obstructions, earwax impaction, inflammation, fluid behind the eardrum, or structural abnormalities.
- Soundproof Booth Positioning: You will be seated comfortably inside a specialized, soundproof audiometric booth designed to eliminate ambient background noise, which could otherwise interfere with your ability to hear faint test tones.
- Headphone Placement: The clinician will place calibrated headphones or insert earphones over or into your ears. These transducers deliver sound stimuli to each ear individually.
- Pure-Tone Audiometry (Air Conduction): You will listen to a series of tones at different pitches (frequencies, measured in Hertz) and volumes (intensities, measured in Decibels). You will be instructed to press a response button, raise your hand, or verbally indicate every time you hear a tone, even if it is extremely faint. This determines your air conduction thresholds.
- Bone Conduction Testing: A small bone vibrator headband is placed behind your ear on the mastoid process. This device bypasses the outer and middle ear, sending vibrations directly to the cochlea. Comparing air and bone conduction thresholds helps localize the source of any hearing loss.
- Speech Audiometry: You will listen to and repeat a series of spoken words at varying volume levels to evaluate your speech reception threshold (SRT) and word recognition score (WRS), which measure how clearly you understand speech.
- Specialist Consultation: Immediately following the diagnostic testing, the clinician will review your audiogram. They will explain the type, degree, and configuration of any detected hearing loss, perform a clinical evaluation, and discuss appropriate management strategies, such as hearing aids, medical therapies, or referral to an ENT specialist.
When is a Combine (Audiometry + Consultation) Performed?
Evaluation of Progressive Hearing Loss
Physicians frequently request a Combine (Audiometry + Consultation) when a patient reports a gradual, progressive decline in their ability to hear. This is common in older adults experiencing presbycusis (age-related hearing loss) or individuals with chronic occupational exposure to noise. Patients often report difficulty understanding speech in noisy environments, such as restaurants, or find themselves constantly increasing the volume on televisions and mobile devices. The diagnostic test quantifies the specific frequencies affected, while the consultation helps differentiate natural aging processes from preventable noise-induced damage, allowing for timely intervention with assistive hearing technologies.
Investigation of Unilateral or Bilateral Tinnitus
Tinnitus, characterized by a persistent ringing, buzzing, roaring, or clicking sound in one or both ears, is a common clinical symptom that warrants a comprehensive audiological evaluation. Tinnitus is often an early warning sign of underlying cochlear damage, microvascular changes, or retrocochlear pathology. When a patient presents with tinnitus, physicians utilize audiometry to determine if there is an associated hearing loss at specific frequencies. The subsequent consultation is vital for counseling the patient on tinnitus management strategies, ruling out serious underlying conditions, and determining if further imaging, such as an MRI, is indicated.
Assessment of Chronic Otitis Media and Middle Ear Disorders
Chronic middle ear infections, fluid accumulation (otitis media with effusion), and structural issues like otosclerosis or ossicular chain discontinuity can significantly impair sound transmission. Clinicians order this combined evaluation to assess the functional impact of these middle ear pathologies. The audiometry test measures the extent of the conductive hearing loss, while the consultation provides a clinical forum to discuss whether medical management, surgical intervention (such as tympanoplasty or stapedectomy), or conservative monitoring is the most appropriate course of action for the patient.
Screening for Ototoxicity Due to Medications
Certain life-saving medications, including platinum-based chemotherapeutic agents (like cisplatin), aminoglycoside antibiotics (such as gentamicin), and loop diuretics, carry a clinical risk of ototoxicity, which can permanently damage the sensory hair cells of the cochlea. Patients undergoing treatment with these drugs require baseline and periodic audiometric monitoring to detect early, high-frequency hearing loss before it affects conversational speech. The consultation portion allows the healthcare team to coordinate with the prescribing physician to adjust drug dosages or explore alternative therapies if ototoxic damage is detected.
Evaluation of Sudden Sensorineural Hearing Loss (SSNHL)
Sudden Sensorineural Hearing Loss (SSNHL) is defined as a rapid loss of hearing of at least 30 decibels across three contiguous frequencies, occurring within a 72-hour period. SSNHL is considered a medical emergency that requires immediate diagnostic confirmation via audiometry. Prompt testing distinguishes sensorineural loss from simple conductive issues like earwax impaction. The immediate consultation is critical for initiating urgent medical therapies, such as high-dose oral or intratympanic corticosteroids, which must be started quickly to maximize the chances of hearing recovery.
What Does a Combine (Audiometry + Consultation) Detect?
The Combine (Audiometry + Consultation) at Dr. Essa Lab is highly sensitive and capable of detecting a wide array of physiological, structural, and functional abnormalities within the auditory system. Clinically, this evaluation can identify:
- Normal hearing sensitivity across the standard frequency spectrum (250 Hz to 8000 Hz).
- Mild, moderate, moderately-severe, severe, or profound degrees of hearing loss.
- Bilateral symmetrical sensorineural hearing loss, typical of presbycusis or systemic ototoxic exposure.
- Unilateral sensorineural hearing loss, which may indicate localized cochlear or retrocochlear pathology.
- Conductive hearing loss, pointing to pathology in the outer ear canal or middle ear space.
- Mixed hearing loss, indicating a combination of both conductive and sensorineural barriers.
- Noise-induced hearing loss, characterized by a classic audiometric “notch” at 4000 Hz.
- Cerumen impaction obstructing the external auditory canal.
- Tympanic membrane perforation or scarring from prior infections or trauma.
- Otitis media with effusion (fluid accumulation in the middle ear cavity).
- Eustachian tube dysfunction leading to abnormal middle ear pressure.
- Otosclerosis, a metabolic bone disease causing fixation of the stapes footplate.
- Ossicular chain discontinuity resulting from physical trauma or chronic infection.
- Meniere’s disease, suggested by fluctuating low-frequency sensorineural hearing loss combined with vertigo and tinnitus.
- Acoustic neuroma (vestibular schwannoma), indicated by asymmetrical high-frequency sensorineural loss and poor word recognition.
- Ototoxicity-induced cochlear damage affecting high-frequency hearing thresholds.
- Presbycusis, the progressive, age-related loss of high-frequency hearing.
- Abnormal speech reception thresholds (SRT) inconsistent with pure-tone averages, suggesting potential functional or central issues.
- Impaired word recognition scores (WRS), reflecting difficulties in speech discrimination even when sound is sufficiently amplified.
- Acoustic trauma resulting from sudden, high-intensity sound exposure.
- Barotrauma-induced damage to the middle ear structures from rapid pressure changes.
- Congenital or hereditary hearing impairments.
- Auditory neuropathy spectrum disorder, where outer hair cells function normally but signal transmission along the auditory nerve is disrupted.
- Referred otalgia and associated subjective hearing complaints related to temporomandibular joint (TMJ) dysfunction.
