“…Therefore, hemodilution is of utmost importance to maintain an adequate microcirculation in the uteroplacental unit during normal gestation. Increased sex hormone levels induce a thrombogenic risk, which may cause a vascular insult to the cochlea, resulting in sudden deafness in antepartum women [1,3]. …”

“…The term “postpartum period” is defined as the time after giving birth that is required for the reproductive organs to return to their nonpregnant state, lasting about 6 weeks [4]. Our recent report found that next to the vestibular migraine, sudden deafness was the second most frequent inner ear disorder in pregnant (antepartum) women [3]. However, sudden deafness in postpartum women is extremely rare, probably because the pathophysiology of sudden deafness in antepartum women differs from that in postpartum women, resulting in various prevalence rates and treatment strategies.…”

Objective: This study reviewed our experience in treating sudden deafness in antepartum (pregnant) and postpartum women during the past 2 decades. Methods: From 1997 to 2016, we have recorded sudden deafness in 16 antepartum (mean age, 32 years) and 3 postpartum (mean age, 31 years) women. Sudden deafness occurred during the 1st, 2nd, and 3rd trimesters in 5, 4, and 7 antepartum women, respectively. In contrast, the mean interval between giving birth and symptom onset in the 3 postpartum women was 18 days. Each patient underwent an inner ear test battery. Results: In 8 antepartum women treated by dextran infusion, the outcome as regards hearing was improved in 7 patients (88%) and unchanged in 1 patient. In contrast, the other 8 antepartum women selected no treatment, and only 1 patient (12%) achieved hearing improvement, exhibiting a significantly better outcome when receiving dextran treatment. For the postpartum women, 2 patients had hearing improvement when treated by antioxidants, while 1 patient retained unchanged hearing without treatment. Conclusion: Medication is needed in sudden deafness in antepartum or postpartum women rather than waiting for a natural course. No adverse effects have been identified in any of the mothers or offspring 1 year after delivery.

“…During pregnancy, the production and excretion rates of sex steroid hormones (estrogen and progesterone) are significantly increased [ 19 ]. In the third trimester, circulating progesterone levels are 20 times higher than basal levels and estradiol levels are 30 to 40 times higher than during the normal menstrual cycle [ 20 ]. These hormonal changes may cause electrolytic imbalance due to excessive retention of sodium and water, which leads to an increase in the volume of extracellular fluid [ 20 ].…”

During pregnancy, physical, hormonal, and psychological changes may occur from conception to labor. Balance is also impacted throughout this time, leading to symptoms such as vertigo and unsteadiness. These symptoms may appear at any time and can cause disability and physical impairment. Little has been published about vertigo in pregnancy. We performed a narrative review of vertigo in pregnant patients. Vertigo in pregnant females may be associated with hormonal changes in peripheral structures and inner ear organs. Meniere’s disease, vestibular migraine, and benign paroxysmal positional vertigo are usually exacerbated during pregnancy. Specific changes to hearing and proprioception in the physical examination are also noted between the second and third trimester of pregnancy. These symptoms are usually seen in pregnant patients throughout this time. Some types of vertigo may be exacerbated and others may present at any time of pregnancy. Further research is needed to understand the clinical and pathological association of audiovestibular symptoms during pregnancy.

“…6 A retrospective study in Taiwan showed that SSNHL was attributed to 21% of inner ear disorders in pregnant women. 7 There have been few reports involving SSNHL in pregnant women because of its rare occurrence. Therefore, little is known of the causes, clinical manifestations, treatments, and prognosis of SSNHL.…”

Clinical management and progress in sudden sensorineural hearing loss during pregnancy

Sudden sensorineural hearing loss (SSNHL) is a relatively rare, but distressing, disease in pregnant women. Little is known about the causes, clinical manifestations, treatments, and prognosis of SSNHL. Some hypotheses have been proposed to explain the pathophysiological mechanism of SSNHL, but most of them have not been identified. This article reviews the existing literature to present a summary of this clinical problem. Most patients suffer from SSNHL in the second or third trimester, and show moderate to profound hearing loss. The interval between the initial treatment and onset of hearing loss is less than 10 days in most patients. Some patients with SSNHL show tinnitus, vertigo, or dizziness, and fullness of the ear. Although some patients have a tendency for self-cure, treatment with intravenous dextran 40 combined with intratympanic corticosteroids is probably a safe and effective therapeutic strategy for pregnant patients with SSNHL. Further clinical research is necessary to identify the best therapeutic strategy for these patients.
