A rare facial nerve anomaly was incidentally discovered whilst performing a tympanoplasty and ossicular reconstruction on a patient with an acquired unilateral conductive hearing loss. The nerve was seen to bifurcate and straddle a normal stapes superstructure as it ran posteriorly through the middle ear, a unique and as yet unreported combination. This case highlights the importance of vigilance regarding facial nerve anatomical variations encountered during middle-ear surgery thus avoiding inadvertent damage. The purported embryological mechanism responsible for such anomalies of the intra-tympanic facial nerve is discussed.

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.)

Conductive Hearing

This study investigated whether conductive hearing loss reduces normal binaural hearing advantages and whether binaural hearing advantages are normal in patients who have had hearing thresholds improved by middle ear surgery. Binaural hearing was assessed at a test frequency of 500 Hz using the masking level difference and interaural time discrimination thresholds. Results indicated that binaural hearing is often poor in conductive lesion patients and that the reduction in binaural hearing is not always consistent with a simple attenuation of the acoustic signal. Poor binaural hearing sometimes occurs even when middle ear surgery has resulted in bilaterally normal hearing thresholds. Our preliminary results are consistent with the interpretation that auditory deprivation due to conductive hearing loss may result in poor binaural auditory processing.

AbstractA three-generation family with Saethre-Chotzen syndrome and an isolated case are presented. The proband presented with conductive hearing loss. His mother and grandmother showed minor features of the syndrome including conductive hearing loss.Symptoms of the craniosynostosis syndromes can include stapes ankylosis, a fixed ossicular chain in a too small epitympanum, and small or even absent mastoids. The proband was treated with a boneanchored hearing aid (BAHA) instead of reconstructive middle ear surgery. Current literature on the results of ear surgery is reviewed. In general, reconstructive middle ear surgery should only be considered if congenital anomalies of the middle ear are the only presenting symptom. In cases with additional anomalies such as atresia of the ear canal or damage due to chronic ear infections, the outcome of reconstructive surgery to correct the anomalous ossicular chain is unsatisfactory. In such cases the BAHA is probably the best solution.

Hearing loss must be divided into conductive hearing loss (CHL) and sensorineural hearing loss (SNHL). CHL is caused by sound not reaching the cochlear (abnormality of the ear canal, tympanic membrane, middle ear, or ossicles), whereas SNHL is a condition affecting the cochlear or auditory (eighth cranial) nerve. Hearing loss may be accompanied by other cardinal signs of ear disease, such as pain or discharge from the ear, vertigo, facial nerve palsy, and tinnitus, which guide the diagnosis. This chapter describes the approach to the patient with hearing loss.

The case of a five year old boy who presented with a lower motor neurone facial nerve palsy secondary to primary non-Hodgkin’s lymphoma (NHL) of the middle ear is discussed. Any child who presents with a facial nerve palsy and conductive hearing loss requires thorough evaluation to exclude the possibility of temporal bone malignancy.

Salivary gland choristoma is an extremely rare middle ear pathology. We present the case of a 10-year-old girl with unilateral conductive hearing loss. Tympanotomy showed a nonspecific middle ear mass, absence of stapes, anomaly of incus, and displaced facial nerve. It was not possible to remove the mass completely. Histology confirmed salivary gland choristoma. The hearing in this case can be improved with a bone-anchored hearing aid.

Background: Otosclerosis is a disease of the osseous labyrinth. The disease causes 5% to 9% of all cases of hearing loss and 18% to 22% of conductive hearing loss. The treatment of choice is a surgery. The hearing improvement after the operation is determined by various factors. Aims/Objectives: The aim of the analysis is to determinate changes in hearing after stapedoplasty in view of surgery side in the patients operated on otosclerosis by right-handed surgeons. Material and Methods: The analysis involved patients hospitalized and operated on otosclerosis between 2012 and 2018. Only patients with their first middle ear surgery due to otosclerosis were included in the study. The patients were operated by 2 right-handed surgeons who used the same surgical technique and had similar experience in otosclerosis surgery. The study included patients who were divided into 2 groups: with self-tightening prosthesis and with manually tightening prosthesis. Results: The procedure performed by right-handed operators on the left side using prostheses requiring manual fixation on the incus was associated with poorer audiometric results compared to the results of surgeries on the right side. In patients with the self-tightening prostheses, the audiometric improvement of hearing was bilaterally comparable independently from operation side. Conclusion: (1) The dependence of hearing improvement on the surgery side was demonstrated in cases of surgeries performed on the left ear by right-handed surgeons, particularly with manually tightening prosthesis. (2) Self-tightening prostheses in stapedotomy limit the human factor, reducing the risk of complications after otosclerosis surgery and provide repeatable hearing improvement.

A high jugular bulb is not an uncommon otologic anomaly. It may be noted as an incidental finding on physical exam, middle ear surgery, or computed tomography of the temporal bones. Frequently the patient is asymptomatic, but a high jugular bulb can occasionally cause tinnitus or conductive hearing loss. The case of a seven-year-old black male with unilateral conductive hearing loss secondary to a high jugular bulb is presented. The diagnosis, differential diagnosis, and management of a conductive hearing loss associated with a high jugular bulb are discussed.

Conductive Hearing

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
