Bone Anomalies

A temporal bone histopathological study was conducted to detect temporal bone anomalies in 20 ears (10 cases) of individuals with congenital heart anomalies. We restricted our study to patients more than one year of age, and to heart anomalies of unknown etiology. The temporal bones were obtained from refrigerated cadavers, fixed in formalin, embedded in celloidin, cut in a horizontal plane, stained with H & E, and mounted on glass slides for light microscopic study. Anomalies observed in the middle ear were: remnants of mesenchymal tissue (8 ears), wide angle of the facial genu (6 ears), persistence of the stapedial artery (5 ears), large defect of the facial canal (4 ears), high jugular bulb (4 ears), and bulky incus (2 ears). Inner ear anomalies consisted of a shortened cochlea (5 ears), anomaly of the horizontal canal (3 ears), anomaly of the posterior canal (2 ears), obliteration of the cochlear aqueduct (2 ears), and patent utriculoendolymphatic valve (1 ear). Most of the anomalies observed appeared to be due to arrested development, and resembled features which may be found at various stages of fetal life. Structural anomalies were more commonly found in the mesoderm than in the ectoderm, and middle ear anomalies were more frequently encountered than anomalies of the inner ear. No definite relationship between these anomalies observed in the temporal bone and hearing problems which had been recorded clinically for these patients could be detected. However, the large defect (more than one third of the circumference) of the facial canal, the high jugular bulb, and the stapedial artery persistence should be recognized as problems since they may be encountered during middle ear surgery.

Central Nervous System Anomalies

Three temporal bones obtained at autopsy from 2 patients with CHARGE association (Coloboma, congenital Heart disease, Atresia of choanae, mental Retardation and/or central nervous system anomalies, Genital hypoplasia, and Ear anomalies) were examined histopathologically. Both temporal bones from 1 patient showed multiple anomalies in the middle ear, inner ear, and facial nerve. However, the temporal bone obtained from the other patient showed almost normal structures in the inner ear, middle ear, and eustachian tube. These results are different from those of 2 previous reports of temporal bone histopathology regarding CHARGE association. This difference suggests that CHARGE association may arise not from one etiopathogenetic factor, but from complex factors. Special attention to dehiscent facial canal and perilymphatic gusher during otologic surgery in patients with CHARGE association is discussed.

Superior Petrosal Sinus

AbstractVariability in the size of the dural sinuses and jugular bulb is not uncommon and usually manifests as a high jugular bulb encroaching upon the floor of the middle ear. A rarer entity is the superior and medial extension of the jugular bulb into the bone of the posterior wall of the internal auditory meatus. We report a case where this anomaly was encountered during acoustic neuroma surgery making exposure of the fundus of the internal auditory meatus technically impossible. The possibility of a communication with the superior petrosal sinus is discussed.

Bone Exposure

The suboccipital-retrosigmoid approach to the internal auditory canal and cerebellopontine angle is being used with increasing frequency for neurotologic surgery, including vestibular nerve section and resection of acoustic neuroma. It offers wide exposure of the cerebellopontine angle and the cranial nerve VII—VIII complex as it courses from the brain stem to the temporal bone. Exposure of the internal auditory canal can be achieved by removing its posterior bony wall. Safe utilization of this approach requires familiarity with the variable position of structures within the petrous bone, including the lateral venous sinus and jugular bulb. We report here a case in which bleeding resulted from injury to a high jugular bulb during surgical exposure of the internal auditory canal via the suboccipital route and discuss the regional anatomy of the jugular bulb based on study of 378 consecutive temporal bone specimens from the collection of the Massachusetts Eye and Ear Infirmary. High jugular bulb was defined as encroachment of the dome of the bulb within 2 mm of the floor of the internal auditory canal. Forty-six percent of scoreable specimens met this criterion. However, when donors less than 6 years of age were excluded, a high jugular bulb was identified in 63% of specimens. Relevance to neurotologic surgery of the posterior fossa is presented.

AbstractA 64-year-old man with right aural discharge presented complaining of progressive deafness. Other otological symptoms were absent and specifically there was no seventh nerve paresis. A right aural polyp was identified and biopsied. Histology showed the polyp to be a schwannoma.Subsequent temporal bone computed tomography showed expansion of the distal facial canal. At operation, the schwannoma filled the middle ear cleft and extended from the genu to the region of the stylomastoid foramen. The floor of the middle ear had been eroded, exposing the jugular bulb.Facial paresis is the usual presenting feature of a facial schwannoma, while deafness, ageusia and reduced lacrimation are variable, dependent upon the site of the lesion. The absence of facial palsy as a presenting feature is very rare and this case illustrates the need for histological examination of all abnormal aural material.

High Jugular Bulb

Nonneoplastic vascular lesions in the middle ear may be arterial or venous. For the former, ectopic location of the internal carotid artery is the most common; a high jugular bulb is the most common venous abnormality. Both may be clinically misdiagnosed without radiographic studies and, in the event, lead to disaster.

Tomography Appearance

Congenital perilymphatic fistula is an abnormal communication between the inner ear and middle ear. Inner ear anomalies have been described on computed tomography scans. Middle ear anomalies have been found at surgery; the most frequent are anomalies of the stapes and round window. This retrospective study describes the appearance of the inner and middle ear on computed tomography scans, and of the middle ear at surgery, in 10 patients (15 ears) in whom perilymphatic fistula was found at surgery. Twelve of 15 stapes were abnormal at surgery; 4 of these 12 (33%) could be seen on computed tomography scans. Two stapes normal at surgery were normal on computed tomography. Three round windows were abnormal at surgery; none of these was seen on computed tomography scans. There were also four dysplastic cochleas, four dysplastic vestibules, and three dilated vestibular aqueducts. Computed tomography scans identified an abnormal inner ear, middle ear, or both in 8 (53%) of the 15 ears with perilymphatic fistula. An inner ear or middle ear anomaly on computed tomography may heighten clinical suspicion of congenital perilymphatic fistula.
