The effect of premature ovarian failure on inner ear function
1Ministry of Health, ENT Clinic, Malatya Training and Research Hospital, Malatya, Turkey.
Summary
Women with premature ovarian failure (POF) and menopause show impaired hearing function compared to healthy controls. Early hearing evaluations are recommended for women with POF to detect potential cochlear damage.
Area of Science:
- Otolaryngology
- Reproductive Endocrinology
- Audiology
Background:
- Premature ovarian failure (POF) affects 1-2% of women, impacting overall health.
- Estrogen deficiency is implicated in hearing disorders, but POF's specific cochlear effects are unclear.
Purpose of the Study:
- To investigate hearing function in women with POF compared to menopausal women and healthy controls.
- To determine if POF is associated with cochlear and auditory pathway dysfunction.
Main Methods:
- Audiometric evaluation including pure tone audiometry (PTA), transiently evoked otoacoustic emissions (TEOAEs), and distortion product otoacoustic emissions (DPOAEs).
- Comparison of hearing test results across three groups: women with POF (n=30), women in menopause (n=30), and healthy controls (n=30).
Main Results:
- Hearing thresholds at 6 and 8 kHz (PTA) were lower in the menopause group than in POF and control groups.
- TEOAEs at 3 and 4 kHz and DPOAEs at 1, 2, 4, and 6 kHz were reduced in the menopause group versus controls.
- DPOAEs at 6 kHz were lower in the POF group than in controls, indicating cochlear dysfunction.
Conclusions:
- Both women with POF and those in menopause exhibit diminished inner ear function compared to healthy individuals.
- Lower estrogen levels in POF may negatively impact hearing, particularly at specific frequencies.
- Clinical assessment of hearing status should be considered for women diagnosed with POF.

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

01:27Ovarian Cycle
3.5K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

3.0K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

01:27Heart Failure I: Introduction
723
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
