“…According to Londero [11], tinnitus is often the only auditory sign associated with hearing loss and more than 80% of patients with tinnitus have an abnormal audiogram. This same finding was shared by Kudamo Song in South Korea and Betty in California [12] [13].…”

Objective: To determine the audiometric profile of deafness in our practice. Materials and Methods: Longitudinal prospective study was conducted out in the ENT department and cervicofacial surgery of Gabriel Toure University Hospital in Bamako, we made an exhaustive sampling of all the patients who consulted for hearing loss, tinnitus, vertigo, hiring report, medical expertise and whose deafness was confirmed to tonal audiometry with an age greater than or equal to 15 years. It was spread over 10 months (June 2016 to March 2017). A total of 200 patients were collected. Exclusion criteria were all patients under 15 years of age as well as deafness related to earwax or foreign bodies, and refusal to participate in the study Results: During our study period, 6055 outpatients were admitted out of which 734 patients underwent audiometric testing and 200 patients (3.30%) met our criteria. The male sex was the most represented with a rate of 60%. The sex ratio was 1.5 or 3 men for 2 women. The 15 to 25 age group was the most represented at 37.5%. The average age was 37.18 years old with extremes ranging from 15 to 83 years old. Pupils/students were the most represented with a rate of 29.5%, followed by housewives in 23%, farmers in 10.5% and military in 10%. As antecedent 26% of our patients had a chronic otitis media (OMC), against 23% who had no antecedent otological and 17% had a traumatic antecedent. Bilateral deafness was the most common with a rate of 64.5%. The mode of progressive appearance was the most frequent in 74.5%. As functional signs 46.22% of our patients had a hearing loss associated with tinnitus. Otoscopic examination was pathological in 34.5% of our patients. Mixed deafness was the most common in 43.35%, followed by perception deafness in 32.19% and transmission How to cite this paper:

“…In the present case, tinnitus was not associated to clinically evident hearing loss; it has been previously reported that lesions affecting the auditory pathways may not determine an evident hearing loss in some cases 15 . Moreover, tinnitus and difficulties in speech perception, especially in noise, are often reported even in the absence of a clinically evident hearing loss 35,36 . Traditional theories assume that tinnitus is triggered by cochlear damage, mainly at the outer hair cell level; however, this would not apply to tinnitus patients presenting with a normal audiogram 36,37 .…”

Multiple Sclerosis (MS) is a chronic inflammatory and neurodegenerative disease of the central nervous system characterized by the destruction of myelin sheaths and axonal loss. Presenting symptoms of multiple sclerosis may vary and if not promptly identified may lead to a delayed diagnosis of Multiple sclerosis. In this paper, we present a rare case of a patient with ageusia as presenting symptom of Multiple sclerosis; the symptom spontaneously resolved after two weeks and was followed by hyposmia, dizziness, tinnitus and facial paraesthesia that eventually led to a clinical diagnosis of Multiple sclerosis. The presence of gustatory, olfactory and audio-vestibular symptoms has been associated with disease activity and progression of several inflammatory and neurodegenerative diseases of the central nervous system including Multiple sclerosis. Gustatory alterations may be due to the presence of demyelinating lesion in the brain area of taste; the progression of the disease may explain the additional olfactory and audio-vestibular symptoms described in this patient. Even if taste alteration is an extremely rare presenting symptom of Multiple sclerosis, its presence in young women should always be carefully investigated as it could be an early sign of Multiple sclerosis.

“…Thus, the mechanism involved in the development of tinnitus may depend on its laterality [43]. Interestingly, it was also found that patients with unilateral tinnitus and normal hearing tended to have a higher THI score compared with bilateral tinnitus sufferers [43]. Tinnitus pitch, mean age of patients, and mean tinnitus duration were higher in the group with bilateral tinnitus [44].…”

“…This scale is a survey with 25 items and divided into three subscales: functional, catastrophic, and emotional, with a total score ranging from 0 to 100. It grades five tinnitus severity categories: slight (0-16); mild (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36); moderate (38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56); severe (58-76); and catastrophic (78-100). Psychoacoustic characteristics of tinnitus, including its loudness and pitch, were measured using the standard clinical method by presenting sounds similar to those described by the patient [27,28].…”

The Prevalence of Different Types of Headache in Patients with Subjective Tinnitus and Its Influence on Tinnitus Parameters: A Prospective Clinical Study

et al. 2020

Both tinnitus and headache are very prevalent conditions in the general population, with bidirectional co-occurrence of them. A number of studies revealed a high prevalence of headache in tinnitus patients; however, most of them used self-reported symptoms, questionnaires, or health databases and were retrospective. The aim of this study was to evaluate the prevalence of different types of headache in a cohort of tinnitus patients and to assess the influence of headache on tinnitus parameters, focusing on appropriate headache and tinnitus diagnosis verified by clinical examination. This prospective study involved 286 patients diagnosed with subjective non-pulsating tinnitus. Patients’ clinical information was thoroughly assessed by the multidisciplinary team, including tinnitus characteristics and severity according to the Tinnitus Handicap Inventory (THI), loudness assessed by the Visual Analogue Scale (VAS), audiometry, type of headache diagnosed according to the third edition of the International Classification of Headache Disorders, severity of headache assessed by the Numeric Rating Scale (NRS), and impact of headache using the Headache Impact Test (HIT). In total, 141 (49.3%) tinnitus patients were diagnosed with headache, most of them with tension-type headache or migraine. They were significantly younger; mostly women; had bilateral tinnitus, vertigo, and depression more frequently; and had hearing loss less frequently as compared with the non-headache group. In total, 82 (58.16%) patients had the same localization of tinnitus and headache. Younger age, female gender, higher tinnitus burden measured by THI, and coexistence of hearing loss were independent variables connected with the occurrence of headache in the tinnitus group. According to our study, headaches impact tinnitus on many different levels and may be an important co-factor for tinnitus subtyping. We recommend screening for headache coexistence in all tinnitus patients.

Audiometric Profiles in Patients With Normal Hearing and Bilateral or Unilateral Tinnitus

Abstract: The mechanism involved in the development of tinnitus may depend on its laterality. Bilateral tinnitus may be associated with hyperactivity at the level of the cochlear nucleus whereas a higher-order cortical area may be involved in unilateral tinnitus.
