Hearing loss during resuscitation.

Tympanic injury secondary to positive pressure mask ventillation is rare. During resuscitative procedures, two patients developed partial deafness, one from disarticulation of the incudomalleal joint, the other from an oval window perilymph fistula. Excessive pressure transmitted rapidly through the eustachian tube is postulated to have caused both injuries.

Congenital cholesteatomata with other anomalies.

Congenital (primary) cholesteatomata may arise in the petrous apex, mastoid, middle ear, or external auditory canal. Histological studies of the temporal bones of a 20-year old man with bilateral combined deafness show bilateral congenital cholesteatomata of the middle ears associated with dalivary choristomata and other anomalies of the middle and inner ears.

Cholesteatoma in children.

The 65 cholesteatomas operated on in children showed a more expansive and rapid growth than those in adults. In one fifth of the cases cholesteatoma filled the whole air-cell area, which was wide in half of the children. Fifty-two ears of these children had an attic or a posterosuperior perforation. One case was complicated by a fistula in the horizontal semicircular canal, and the ossicular chain was unbroken in 23 cases (35%). Thus, the findings support the idea of the primary soft-tissue spread of cholesteatoma in children. Five ears (8%) discharged postoperatively, and three ears (5%) were reoperated on and showed residual tympanal cholesteatoma. Cavity obliteration with canal wall down technique proved safe, even in the cases of the most extensive and active cholesteatoma.

Use of tragal cartilage with the total ossicular replacement prosthesis.

A method was developed for the use of tragal cartilage and perichondrium with the total ossicular replacement prosthesis. The method involves securing the flat base of the prosthesis in a perichondrial tunnel on the cartilage to stabilize the prosthesis, prevent extrusion, and promote vascularization.

Experience with a polyethylene total ossicular replacement prosthesis.

Surgical reconstruction of ossicular defects in chronic middle ear disease is a difficult problem. We have reviewed our results with the use of the Plastipore total ossicular replacement prosthesis (TORP). Of 29 procedures that were analyzed, nine were considered successful. None of our patients had a stapes superstructure, and 13 had no malleus. Placement of the TORP under the malleus handle and use of extra tissue between the prosthesis and the tympanic membrane provided better hearing results, but extrusion of the prothesis still occurred. Positioning of the prosthesis and contraction of the middle ear space, which causes extrusion of the prosthesis, remain problems in this type of reconstruction.

Cystic fibrosis and hearing loss.

The mucosal epithelium of the middle ear and Eustachian tube is in direct continuity with the upper respiratory tract. Since the otolaryngological aspects of cystic fibrosis (CF) are dominated by involvement of the paranasal sinuses, it might be assumed that children with CF would be expected to have a higher than usual incidence of middle ear disease. Eighty patients who were afflicted with CF had audiological evaluations, which consisted of hearing threshold levels (250 to 8,000 Hz) and speech and impedance audiometry. We found no greater incidence of a conductive or sensorineural hearing loss in patients with CF when compared with a normal age-adjusted population.

Ossicular manipulation in chronic ear surgery. An electrocochleographic study.

Twelve patients were submitted to ossicular dissections for between 2 1/2 and 35 minutes during ear surgery. A comparison between premanipulatory and portmanipulatory electrocochleographic threshold determinations did not disclose any thrshold shifts. The results lend support to the conclusion that manipulations on ;the ossicular chain, performed with customary care, are less harmful to the inner ear than other generally recognized threats to the cochlea during surgery, eg, perilymph fistulae and acoustic traumas from the drill.

The effects of an adhesive in the middle ear.

This study investigated the effects of enbucrilate (Histoacryl) on the middle ear. Small amounts of the adhesive were used in 81 middle-ear operations performed on 50 rabbits. Light microscopic investigation of these ears 1, 2, and 3 months after surgery showed bone necrosis and a granulation tissue reaction surrounded by foreign-body giant cells. Inner-ear changes were observed in a third of the cases. Therefore, enbucrilate should only be used with extreme care and in minute quantities and never near the labyrinthine capsule.

Recurrent meningitis due to a congenital fistula in the stapedial footplate.

A patient with recurrent meningitis had spontaneous CSF leakage from the fistula of the stapedial footplate. The patient was a 7-year-old boy with profuse CSF otorrhea, proved by myringotomy. A roentgenographic examination and computed tomography scan of the temporal bone demonstrated an abnormal bony labyrinth. During the operation, a leak was found at the fistula of the stapedial footplate. Surgical obliteration of the fistula with temporal muscle and fascia has prevented the recurrence of meningitis.
