Hearing assessment in developmentally impaired infants: classical conditioning as a supplement to brainstem-evoked response audiometry (BERA).

The brainstem-evoked response audiometry (BERA) is probably the most common approach to hearing assessment in high-risk and developmentally handicapped infants. It is usually suggested, however, that BERA should not be the sole assessment method. In an attempt to determine an effective supplement to BERA, the present study evaluated a classical conditioning procedure with developmentally impaired babies. Within this procedure, different tones served as conditioned stimuli while an air-puff was used as the unconditioned stimulus. Results indicate that this procedure could be successfully applied with almost all of the babies.

Hearing loss in the cervico-oculo-acoustic (Wildervanck) syndrome.

A 22-year-old woman with mixed hearing loss, Klippel-Feil anomalad (fused cervical vertebrae), and bilateral abducens palsy with retracted bulb (Duane's syndrome) is classified as having the cervico-oculo-acoustic syndrome or Wildervanck syndrome. In this syndrome, the unilateral or bilateral congenital hearing loss is usually severe and of neurosensory origin. To our knowledge, this is the third case of this syndrome with the classical triad and a mixed hearing loss. It is the second case in which an exploratory tympanotomy was performed. An ankylosis of the stapes was found. Stapedectomy and Teflon interposition were successfully carried out. Since the triad of the cervico-oculo-acoustic syndrome can be incomplete, a review of the association of Klippel-Feil anomalad and hearing loss is also presented, with special attention to the anomalies of the ossicular chain.

The disco-malleolar ligament: a possible cause of subjective hearing loss in patients with temporomandibular joint dysfunction.

The presence of aural symptoms in patients with temporomandibular joint dysfunction has been known for a long time. Although many suggestions have been made as to their cause, none has yet proved adequate. In this article reports are given on four patients with temporomandibular joint dysfunction presenting with aural symptoms, the pertinent literature is reviewed, and a new theory of their causation is discussed.

Hearing assessment in young infants by means of a classical conditioning procedure.

A classical conditioning procedure, in which tones of different intensities and frequencies constituted the conditioned stimuli and an air puff on the corner of the infants' eye represented the unconditioned stimulus, proved to be an effective device for evaluating the hearing ability of young babies. The 45 infants participating in the present study were able to start responding to the presentation of the tones (i.e. complete and prolonged closure of their eye before the onset of the air puff or independent of the puff) in a relatively short period of time. The presence of responding could be regarded as a reliable sign of the infants' hearing functioning across frequencies and intensities.

The facial nerve coursing across the oval window area.

A case of unilateral conductive deafness since birth is described. At exploration of the middle ear, the facial nerve was found to have an anomalous course across the oval window region, the stapedial crura ending on the uncovered facial nerve. This case is believed to represent the 9th case to be recorded. This anomaly may be due to failure of union between the branchial part and otic capsule part of the stapes, in combination with a defective development of the laterohyale resulting in a partially absent facial canal.

The facial nerve coursing across the promontory with a persistent stapedial artery.

A case of congenital bilateral conductive deafness is described. Some years ago absence of the oval window was found in the left ear. Exploratory tympanotomy of the right ear revealed a large persistent stapedial artery while the facial nerve took its course from the geniculate ganglion straight down across the promontory anteriorly of the stapedial artery.
