Tumor Of Middle Ear Research Articles

鼓室型中耳ぼう神経節腫例

A 61-year-old woman had paraganglioma located only in the tympanic cavity. She complained of pulsatile tinnuitus and hearing loss in the left ear. Middle eartumor was diagnosed by CT scan and carotid angiography. No tumor recurrence was confirmed and ossiculoplasty was performed 6 months after surgical removal of the tumor in the tympanic cavity.The importance of early diagnosis and treatment and the necessity of exact histological diagnosis of this tumor are discussed.

Ectopic Internal Carotid Artery Seen Initially as Middle Ear Tumor

An ectopic carotid artery is rare. Its first symptoms may be neurological and could bring the patient to the neurologist during the initial evaluation. However, more often, the neurologist examines a patient in whom serious neurological deficit has occurred after transtympanic exploration of an undiagnosed vascular mass. Because diagnosis can be definitively established by angiography and the consequences of injury to an aberrant carotid artery are serious, operative exploration of vascular middle ear masses probably should be deferred until an ectopic carotid artery has been excluded by angiography.

Primary Middle Ear Adenoma

A case of glandular middle ear tumor of salivary tissue or salivary like tissue is presented. The rarity of this type of middle ear tumor caused initial difficulty in arriving at a diagnosis at the time of surgery. The current opinion in the literature as to the etiology of such tumors is divided among ceruminous glands, middle ear mucosal metaplasia and ectopic salivary gland tissue. Experience with more additional cases will help to establish etiological concept and will increase our knowledge as to treatment and prognosis.

Delayed onset of hypopituitarism: Sequelae of therapeutic irradiation of central nervous system, eye, and middle ear tumors

Four children with short stature who received irradiation to the head in conventional doses had clinical and laboratory evidence of hypothalamic-pituitary hormone deficiencies several years later. Growth hormone was deficient in all. One patient also had evidence of TSH, ACTH, and gonadotropin deficiency. Basal prolactin levels and prolactin response to synthetic TRF were normal in all patients tested. Treatment with human growth hormone significantly increased growth rate. We suggest that children should have the hypothalamic-pituitary area shielded from irradiation. Periodic measurements of hypothalamic-pituitary function should be performed in children who have had irradiation to the head, in order to detect and treat hormonal deficiencies before growth and development are seriously compromised.

Acoustic neurinomas presenting as middle ear tumors.

AbstractSince the advent of the widespread use of the operating microscope and the excellent graduate and post‐graduate training in otology, more and more otosurgeons are exploring disease of the middle and inner ear; consequently, more and more unusual and varied anomalies and tumors are being described. This paper describes the unusual presentation of acoustic neurinomas in the middle ear.Most acoustic nerve tumors arise within the meatus of the internal auditory canal, producing the syndrome of the cerebellopontine angle.In the first case presented, the tumor did not arise in the usual location, and this points out the fact that acoustic nerve tumors may arise anywhere along the course of the VIIIth nerve. It is felt that the tumor must have arisen in one of the smaller branches of the inferior vestibular nerve, lateral to the vestibule, as it did not extend medially beyond the medial wall of the vestibule. Instead, it presented in the cochlear windows as a middle ear tumor.In the second case, the tumor apparently arose in the usual location, in the meatus of the internal auditory canal. Its lateral extension was unusual, in that the tumor filled the entire labyrinth and presented as a middle ear tumor in the cochlear windows of the middle ear, and its extension medially, produced the classical findings of the cerebellopontine angle tumor.

Middle Ear Neoplasms with Imperforate Drum

Middle ear neoplasm with imperforate drum is seldom seen due to the difficulty of the early detection. Two operated cases of such condition are dealt with in this paper. The first case is the adenoid cystic carcinoma of 17 years old male and the second is the glomus jugulare tumor of 59 years old male. The symptoms of these two cases are full feeling, tinnitus and hearing loss of the conductive type in the affected ear, which are not particular only to this condition. Each case showed 3 years' and 2 years' survival without recurrence after the operation respectively. The early detection of the middle ear neoplasm leads to the good result. So as to confirm this condition at an early stage of clinical course it seems very important for the otologist to keep in mind the presence of mass lesion of the middle ear and its clinical features. It is authors' opinion that the drum is natural anatomical barrier in this neoplastic condition of the middle ear. From this view point the clinical stage of the middle ear neoplasm is classified into three stages, which is described in this paper.

The internal carotid artery presenting as middle ear tumor.

AbstractAn additional case of an anomalous course of the internal carotid artery presenting as a middle ear tumor is described. Recognition of the existence of this entity resulted in the correct diagnosis by arteriography. A plea is made for arteriographic study of all “vascular” middle ear tumors prior to surgical exploration and biopsy.

Middle ear and mastoid neoplasm

Middle ear and mastoid neoplasm

Mucous-secreting cyst of the middle ear. Possible origin from the first pharyngeal pouch.

REVIEW of the literature reveals that a middle ear cyst possibly arising from remnants of the first pharyngeal pouch is a unique entity. A case is presented which was diagnosed preoperatively as a middle ear tumor, associated with a recent ipsilateral facial nerve paralysis. <h3>Report of a Case</h3> A 39-year-old white woman was admitted to the Chicago Wesley Memorial Hospital, nine days after awakening with a clinically complete, left facial paralysis. The family physician had diagnosed a Bell's palsy and administered a "penicillin injection." Three days later the patient returned to the physician complaining of a "needles and pins" pain in the left ear, and was referred to an otologist. The admission history indicated that the patient recalled about ten episodes of brief, foulsmelling yellowish drainage from the involved ear during the past 20 years. A mild earache usually occurred at the onset. She was not aware of any

METASTASES OF GLOMUS JUGULARE TUMORS.

Introduction THE GLOMUS JUGULARE, a normal structure first described by Guild, 3 lies in the dome of the jugular bulb just below the floor of the middle ear. The is quite small, 0.5 × 0.25 mm, and is composed of nonchromaffin staining paraganglia cells arranged in an organoid pattern. No physiological function has yet been proved, but neoplasms of this tissue are the most frequent type of middle ear tumor 12 and were first described by Rossenwasser. 9 Much confusion as to the nomenclature, clinical signs and symptoms, instance of metastases, and proper therapy of these tumors remains. The purpose of this report is to review the nine cases of glomus tumors with metastases and to record an additional instance of distant spread to the lungs. Material and Methods Medical literature was reviewed for reports on cases of metastatic glomus tumors. The more interesting features of the nine

True cholesteatoma; a report of two cases.

A true cholesteatoma of the temporal bone is a rare tumor, derived from a congenital epidermal rest.1-6This is in marked contrast to the rather common pseudocholesteatoma associated with a marginal perforation of the tympanic membrane and chronic aural suppuration.1,3,6,7During the last year and a half two cases of apparent true cholesteatoma have been treated. One presented itself as a middleear tumor, the other as an idiopathic facial nerve paralysis of seven months' duration. Case1.—An 8-year-old boy was first seen in March, 1956, because of left ear pain, for one day, three weeks previously. He had had an earache two years before without otorrhea, but no other ear trouble. A hearing loss had not been noted. Examination revealed a boy in excellent health with a normal nose, throat, and right ear. There was bulging of the pars flaccida and posterior superior quadrant of the left tympanic
