Surgery of the tympanic bulla (otitis media and nasopharyngeal polyps).

Surgical management of otitis media includes the following options: myringotomy, flushing of the tympanic cavity, lateral bulla osteotomy, ventral bulla osteotomy, and curettage of the tympanic cavity. Combining one of the above procedures with an operative procedure of the external ear canal is frequently indicated because otitis media commonly accompanies chronic otitis externa. The selection of a surgical procedure to treat otitis media should be based on duration of clinical signs, response to previous treatment, the condition of the external ear canal (vertical and horizontal parts), and the familiarity of the surgeon with the different approaches and techniques. Nasopharyngeal polyps may be removed by excising them from the pharynx, external ear, or middle ear. Because of their frequent involvement of the middle ear cavity, nasopharyngeal polyps are best excised by using a bulla osteotomy technique in combination with other excision techniques.

Peripheral vestibular syndrome in the dog: a review of 83 cases.

Clinical data and follow-up evaluations of 83 cases of peripheral vestibular syndrome in the dog were reviewed. The absence of physical abnormalities of the tympanic membrane and absence of radiographic changes within the tympanic bulla or petrous temporal bone were the criteria used to make the diagnosis of idiopathic benign vestibular disease. When grouped according to the cause of the syndrome, most of the dogs had been diagnosed as having either otitis media/interna (49%) or idiopathic benign vestibular disease (39%). Clinical evidence suggested that most of the cases of otitis media/interna were secondary to otitis externa.

Ciprofloxacin in oral treatment of ear infections.

In a pilot study 29 cases of suppurative otitis were treated with ciprofloxacin. Acceptable clinical results were obtained in case of chronic otitis media without cholesteatoma and in case of otitis externa. Cholesteatoma and mastoid cavity cases gave no satisfactory results. Guidelines are proposed to define the specific indications and place of this drug in suppurative otitis.

Swimming and ear infection.

Surface swimming in fresh or ocean water is not contraindicated in children with otitis media or in children with tympanostomy tubes. Diving should be prohibited in children with acute or chronic otitis media or in children with tympanostomy tubes. Hot tub water, bath water, chlorinated water, or water from stagnant ponds may pose a risk for either otitis media or otitis externa.

Facial and vestibulocochlear nerve disease in six horses.

In 6 horses, clinical signs of illness implicated a lesion involving the facial and vestibulocochlear nerves. One horse had signs of otitis externa. Five horses had radiographic changes primarily involving periosteal bony proliferation of the stylohyoid bone at its articulation with the temporal bone. Five horses improved with antibiotic therapy. Otitis media-interna was found at necropsy of one horse.

[Clinical experience with cefadroxil in otorhinolaryngological infections].

Cefadroxil (CDX), a new semisynthetic cephalosporin derivative, was administered to 20 patients with acute or chronic otolaryngological infections and following results were obtained. Of 11 cases with acute infections such as acute otitis media, acute otitis externa and postoperative maxillary cyst, excellent, good and fair results were obtained in 10 cases, the efficacy ratio being 91%, while the efficacy ratio in 9 cases with chronic infections such as chronic pharyngolaryngitis and chronic otitis media was 56%. CDX is, therefore, extremely effective for acute otolaryngological infections. No severe side effect was observed, although there were 2 cases with minor adverse effects, one with drug induced eruption and the other with stomatitis.

Otolithiasis in three dogs.

Mineral opacities within the tympanic bullae, termed otoliths, were detected in three dogs by means of radiography and computed tomography. Radiographic signs of otitis externa were present in two dogs. One dog had clinical signs of vestibular disease, whereas the other two dogs had no clinical evidence of ear disease. Otolithiasis may represent mineralized necrotic material of a current or previous case of otitis media.

Bacterial flora of the external canal in diabetics and non-diabetics.

Diabetics are prone to severe Pseudomonas otitis externa, but it is unknown if this is due to abnormal colonization of the external auditory canal. The bacterial and fungal flora of 26 diabetics and 29 age-matched controls was studied and found to be similar. Subjects with diabetes had more cerumen and a past history of more frequent external otitis than non-diabetics. It is concluded that diabetics probably have more frequent and severe external otitis because of undefined abnormal host defense mechanisms and not because of enhanced colonization by pathogens.

Are ABH antigenic determinants on human outer ear canal epithelium responsible for Pseudomonas aeruginosa infections?

The outer ear canal expression of ABH human blood group antigens has been analyzed with a standardized routine histological procedure by monoclonal antibodies in the case of blood groups A and B, and a corresponding lectin in the case of blood group 0, respectively. In all 20 cases the blood groups were histochemically confirmed. Furthermore, Pseudomonas aeruginosa-specific inhibition experiments were performed with different sugar solutions as well as A-like substance incubating outer ear canal tissue sections with P. aeruginosa strain (No. 60) presenting lectin specificity for N-acetyl-galactosamine (GalNAc). P. aeruginosa lectins with GalNAc specificity apparently adhere to GalNAc as terminal blood group A determinant and indicate that patients presenting with blood group A may have a genetic predisposition to this form of otitis externa.

[Otologic determining factors on infra-red tympanic thermometry in children].

OBJECTIVE: To evaluate the influence of different otoscopic findings on body thermometry in children using an infra-red tympanic thermometer. PATIENTS AND METHODS: Body temperature was measured on healthy right and left ear canals with Thermoscan systems. Moreover, it was determined on children with altered otoscopy, companng to normal contralateral ear. To assess its diagnostic fiability, accuracy ratios were calculated in different temperatures. RESULTS: Temperature measured bilaterally did not offer differences, and intra/interassay variation ratios were always less than 0.34%. Acute otitis externa increased tympanic thermometry a mean of 0.36 degrees C (p < 0.001), and cerumen and previously radical surgery decreased a mean of 0.62 and 0.53 degrees C, respectively (p < 0.001). CONCLUSIONS: The conditions mentioned before modify body thermometry if measured by infra-red tympanic thermometer. So, this system must be avoided in these circumstances. Otitis media, fluid in middle ear, tympanic perforation and ventilation tubes did not modify thermometric results.

[Subacute and chronic mastoiditis in the elderly: report on 10 cases including 5 with a Bell's palsy complication (author's transl)].

Ten elderly patients with subacute or chronic mastoiditis, including 5 with a complication Bell's palsy, were treated. 1) mastoid infections in elderly patients can present the typical characteristics as seen in younger subjects, this being the case in 4 of the 10 cases. 2) The findings in the other 6 patients confirmed facts, that are known or suspected, relating to the sometimes extremely serious and rapidly progressive nature of the affection, due to almost total lack of defences of the organism in elderly patients, often also diabetic, where the causal germ was invariably pyocanic. 3) In 3 cases, after removal of large amounts of wax with great difficulty, there was the very rapid development of a true malignant otitis externa with a Bell's palsy, and extensive bone involvement extending well beyond the region of the tympanic cavity.

Effects of otitis on hearing in dogs characterised by brainstem auditory evoked response testing.

Hearing function was measured in normal dogs and in dogs with otitis using brainstem auditory evoked response testing. Data were obtained from 86 normal ears and from 105 ears with otitis, categorised into four degrees of severity. The data were analysed to illustrate the differences between the hearing function in the normal and abnormal ears and to estimate the degree of impairment associated with differing degrees of pathology. While severe hearing loss seemed to be present in the dogs with more severe otitis, only two individuals were identified as being totally deaf in the affected ears and no dogs were identified in which the cleaning and examination processes had caused damage to hearing function. Cleaning the ear canal produced measurable improvements in hearing in several dogs, indicating the profound effect of physical obstruction of the external ear canal by debris. It is concluded that most dogs with chronic otitis externa are not totally deaf and that the hearing impairment that does occur has the characteristics of conductive hearing loss.

Safety and patient experience with transtympanic electrocochleography.

OBJECTIVES/HYPOTHESIS: Transtympanic electrocochleography (t-ECOG) is a sensitive diagnostic instrument used for Meniere's disease. It is sensitive by virtue of the recording electrode's position on the promontory of the cochlea where the signals are generated. There is concern about the invasive nature of t-ECOG in comparison to extratympanic recording techniques. The purpose of this study was to examine the safety issues, complications, and patient experience with t-ECOG. STUDY DESIGN: Observational study utilizing retrospective chart review and patient survey. METHODS: The medical records of 205 patients who underwent t-ECOG were reviewed for complications. Complications included persistent tympanic membrane perforation, hearing loss, otitis media, otitis externa, ear canal injury, hemotympanum, and pain. An additional 36 patients undergoing t-ECOG were surveyed on subjective measures such as pain during topical anesthesia of the tympanic membrane, during transtympanic placement of the needle electrode, and during the test procedure and overall experience with t-ECOG. RESULTS: There was one case of a nonhealed, persistent perforation in the setting of acute otitis media directly as a result of t-ECOG. Two patients developed otitis media, and three patients had ear pain for up to 5 days. All 36 patients felt the procedure to be tolerable with minimal discomfort. CONCLUSIONS: Transtympanic electrocochleography may be performed with good patient acceptance and infrequent complications.

[Bacterial flora of the external ear canal. 1. Cancer patients].

The bacterial flora of the external ear canal was investigated in a group of 64 patients with head and neck cancer, to observe why otitis externa frequently occurs in cancer patients. Staphylococcus epidermidis (48.5%), Pseudomonas sp. (18.8%), and Flavobacterium sp. (16.8%) were the prominent isolates from ear samples, and Gram-negative organisms which rarely existed in normal canal, were found to be markedly increased (59.4%). Moreover, about half of all non-sterile ear canals were found to have more than one Gram-negative flora. We have concluded that cancer patients probably suffer from external otitis more frequently because of enhanced colonization by Gram-negative pathogens.

Otitis caused by Scedosporium apiospermum in an immunocompetent child.

Scedosporium apiospermum (Pseudallescheria boydii) is a ubiquitous saprophytic mold. It is considered an infrequent but important and emerging human pathogen, mostly in immunocompromised hosts. Otomycosis secondary to S. apiospermum is extremely rare. We report an 8-year-old immunocompetent male who developed otitis media and otitis externa from S. apiospermum, which was successful treated with combination of surgical debridement and topical clotrimazole therapy. A brief literature review of infections caused by S. apiospermum follows the case presentation.

Horner's syndrome in dogs and cats: 100 cases (1975-1985).

The medical records of 74 dogs and 26 cats with Horner's syndrome (HS) that were admitted to the New York State College of Veterinary Medicine between January 1975 and October 1985 were reviewed. In dogs, but not cats, HS was associated significantly (P less than 0.01) with increasing age. Dogs with hypothyroidism (defined liberally but not rigorously), intracranial neoplasia, or thoracic neoplasia, cats with otitis media/interna (defined liberally), and dogs and cats with brachial plexus root avulsion were at greater risk for developing HS than were animals that were hit by a car. Dogs and cats with otitis externa were at less risk of developing HS than were animals that were hit by a car. The cause of HS could not be determined in 50% of dogs and 42.3% of cats. The results of topical adrenergic drug testing in dogs were inconclusive in localizing lesion site. In dogs and cats, HS appeared to be unassociated with gender, breed, or right vs left side. The important causes of HS in dogs and cats were trauma (hit by car), brachial plexus root avulsion, intracranial and thoracic neoplasia, and otitis media/interna.
