The conductive SISI (short increment sensitivity index) test is an indirect procedure to estimate bone-conduction thresholds for middle ear pathology patients. A series of SISI tests are run, beginning at 20 dB S.L. and increasing in 10 dB S.L. steps, until a 100% SISI score is obtained. The following equation predicts the bone-conduction threshold: [Formula: see text] The results of 25 conductive SISI tests on a conductive hearing loss group indicate that the equation approximates the measured B.C. threshold. There was no statistical difference between the predicated B.C. thresholds (12.4 dB) and measured B.C. thresholds (10.4 dB) for the group.

AbstractThe diagnosis of conductive hearing loss is usually based on audiological methods and radiology. The aim of our study was to show that there is a useful additive method to clarify the findings of diseases with conductive hearing loss.Patients (151 ears) with conductive hearing loss were examined using several methods: otomicroscopy, air- and bone-conduction threshold, pure tone average, speech threshold, speech discrimination, tympanometry and stapedial reflex and tympanoscopy.The management of the patients changed in 17 per cent of cases due to tympanoscopy. In a group with normal tympanic membrane the movement of the stapes during endoscopy was compared to stapedial reflex. Stiff stapes were found more often than an abnormal stapedial reflex.Middle ear endoscopy can increase the accuracy of diagnosis of conductive hearing loss thus enhancing decision making in the case of the patient.

Up to 3 million people in Britain might be helped by hearing aids.1 2 Most are over 65 years of age, but some are infants. All should be referred to specialist centres for assessment as soon as possible. Hearing aids generally help most in disorders of the middle ear (conductive hearing loss); they can also help those with sensorineural and other forms of hearing loss. The use of an aid often needs to be supplemented by lip reading and other means of auditory training.1 3

We recorded auditory-evoked magnetic responses with a whole-scalp 122-channel neuromagnetometer from seven adult patients with unilateral conductive hearing loss before and after middle ear surgery. The stimuli were 50-msec 1-kHz tone bursts, delivered to the healthy, nonoperated ear at interstimulus intervals of 1, 2, and 4 seconds. The mean preoperative pure-tone average in the affected ear was 57 dB hearing level; the mean postoperative pure-tone average was 17 dB. The 100-msec auditory-evoked response originating in the auditory cortex peaked, on average, 7 msecs earlier after than before surgery over the hemisphere contralateral to the stimulated ear and 2 msecs earlier over the ipsilateral hemisphere. The contralateral response strengths increased by 5% after surgery; ipsilateral strengths increased by 11%. The variation of the response latency and amplitude in the patients who underwent surgery was similar to that of seven control subjects. The postoperative source locations did not differ noticeably from preoperative ones. These findings suggest that temporary unilateral conductive hearing loss in adult patients modifies the function of the auditory neural pathway. (Otolaryngol Head Neck Surg 1998;119:125-30.)

Otosclerosis is the most frequent cause of conductive hearing loss in patients with intact tympanic membrane. It can be treated by surgery with various techniques. Because of limited manipulation and comparably similar results, stapedotomy at present is preferred over other surgical techniques by most surgeons. Here we present the operative results of 35 otosclerotic patients who underwent stapedotomy between January 2009 - October 2010 in the department of Otolaryngology- Head & Neck Surgery of Bangabandhu Sheikh Mujib Medical University, Dhaka Medical College Hospital and Shahid Suhrawardhy medical college & hospital, Dhaka. The aim of this study was to evaluate the hearing results following stapedotomy in otosclerosis surgery. The average air-bone gap of patients improved significantly to 21.74 dB after operation. Other hearing parameters of patients (including air conduction, bone conduction, speech discrimination score, and tinnitus) also improved. No patient experienced persistent vertigo after the operation and pre operative tinnitus resolved in 12 out of 22 patients. Stapedotomy is a safe and effective modality for improving conductive hearing loss in otosclerotic patients. Bangladesh J Otorhinolaryngol; October 2019; 25(2): 85-93

Abstract Introduction Bone conduction hearing systems can be applied through non-invasive devices, using soft bands that exert pressure on the skin, or they can be surgically implanted (Bone Anchored Hearing Aid - BAHA). However, these bone conduction devices are frequently not well accepted due to the pressure on the head. Therefore, a new non-surgical hearing system was developed not to exert pressure on the skin, the ADHEAR. The bone anchorage in ADHEAR is performed through an adhesive adapter and is indicated for patients with conductive hearing loss and normal inner ear function. Objectives Evaluate the audiological performance with the adhesive bone conduction hearing device (ADHEAR) in a patient with conductive hearing loss. Methodology The study was designed as a prospective single-subject repeated-measure study with the subject serving as his own control. A 29 year old female patient who had a primary surgery due to middle ear cholesteatoma, was adapted with unilateral non-invasive adhesive bone conduction system for the treatment of conductive hearing loss. Air and bone conduction thresholds, word recognition scores (WRS) and speech recognition thresholds (SRT) in quiet and noise were assessed to verify the inclusion criteria of the study. Aided and unaided pure tone audiometry at 0.5, 1, 2 and 4 kHz in free field and speech audiometry in quiet and noise were performed at baseline and after 4 weeks with the ADHEAR. Results The functional gain with the ADHEAR averaged over 0.5, 1, 2, and 4 kHz after 4 weeks of usage of the adhesive hearing system, improved from 55 dB HL to 31dB HL. Speech perception in quiet and noise improved significantly in the aided situation, with SRT in quiet improving from 60 to 35 dB HL, when compared to the unaided condition. Similar results were found in noise. The patient evaluated the ADHEAR system as being useful, and without complaints of skin pressure. There was no adverse skin reaction. Conclusion Hearing performance was significantly better with ADHEAR under all test conditions. Therefore, this transcutaneous hearing system seems to be an excellent alternative for patients who need a hearing solution for conductive hearing loss but for clinical reasons cannot undergo surgery or conventional hearing aids. Furthermore, it preserves skin over the mastoid and reduces the risk of infection. Otherwise it has benefits verified by absence of head pressure and improvement of patient’s quality of life.
