Far-advanced Otosclerosis
cochlear; Otorhinolaryngology
Far-advanced otosclerosis (FAO) is an uncommon diagnosis. Hearing levels in patients with FAO may range from profound loss, by air conduction and fragmentary bone conduction thresholds, to no measurable air or bone conduction thresholds. Thus, FAO may be difficult to distinguish from a sensorineural hearing loss. This report presents the results of surgery in 73 ears with FAO, 77 percent of which had improvement in air conduction thresholds of greater than 20 dB. Discrimination was improved by more than 15 percent in 54 percent of cases, and 75 percent realized improvement in use of a hearing aid. There was no evidence that success was related to preoperative hearing. The surgical results of a subgroup of 14 patients having bilateral FAO were also analyzed. For all 14, similar surgical outcomes were achieved in both the initial and the contralateral ear, with six successes bilaterally and eight failures bilaterally. Although far advanced otosclerosis is uncommon and difficult to diagnose, surgery is worthwhile.

Otosclerosis often occurs as a unilateral mixed or conductive hearing loss. In the absence of retrocochlear findings, otologists usually do not pursue further diagnostic testing. A patient who presented to the Warren Otologic Group with a unilateral mixed hearing loss is discussed. He was followed for 1 year with the intent of scheduling a stapedectomy. Two weeks prior to the surgical date, the patient developed a sudden hearing loss and was admitted to the hospital for treatment. Magnetic resonance imaging demonstrated a tiny, enhancing mass in the lateral internal auditory canal, measuring 7 mm in diameter. At surgery, the tumor was found to originate at the union of the nervus intermedius and the facial nerve. The simultaneous occurrence of facial nerve neuroma and otosclerosis is discussed, with emphasis on a thorough evaluation of all unilateral mixed hearing losses, including those attributable to otosclerosis.

Early speech changes in children with multichannel cochlear implants
Otorhinolaryngology; perception; performance; Surgery
A number of studies have demonstrated that cochlear implants provide an improved auditory signal and enhance the development of speech-perception and production skills for profoundly deaf children, However, exactly when these early speech skills begin to develop remains unclear, To explore this issue, we observed, for a 1-year period, four prelingually deaf children who underwent implantation consecutively within 1 month of each other, and we paid particular attention to the first few months of rehabilitation. We found immediate speech scores as early as the first day of implant tune-up, Speech production continued to improve rapidly throughout the first 4 months but exhibited a generally slower rate of progress in some of the speech-production skills at 1 year, We also found vowel-production skills to be the easiest to achieve, with word-pattern recognition and consonant voicing of intermediate difficulty, Consonant placing and manner of consonant production were the hardest skills to achieve, Results of speech-perception tests 1 year after implantation were markedly improved over preimplantation levels in three of the four children, These early speech changes stress the need for maximization of the capability of the cochlear implant by institution of immediate and intensive speech rehabilitation efforts for prelingually deaf children.
