BACKGROUND: Ear, nose and throat foreign bodies (FBs) are common occurrences particularly among children. This study reviewed the clinical spectrum of ENT FBs, their treatment and outcomes as seen in a tertiary health center in North Western Nigeria. METHOD: The study was a retrospective chart review of patients that were managed for FB impaction in a tertiary health institution in North Western Nigeria over a four year period. RESULT: There were 239 patients; M: F: 1...

BACKGROUND: Aspergillus spp. are saprophytic opportunistic fungal organisms and are a common cause of otomycosis in humans. Although there have been case reports of Aspergillus otitis externa in dogs, to the best of the authors' knowledge, this is the first retrospective case series describing Aspergillus otitis in dogs and cats. OBJECTIVE: To characterize signalment, putative risk factors, treatments and outcomes of a case series of dogs and cats with Aspergillus otitis...

STUDY DESIGN: Case report. SETTING: A tertiary care pediatric hospital. PATIENT: A 7-year-old boy complained of retroauricular pain 3.5 years after cochlear implantation. Temporal bone computed tomographic scan revealed a soft tissue density filling the mastoid and middle ear space. There was extensive osseous erosion involving the cochlear promontory that resulted in lateral displacement electrode array into the middle ear space. INTERVENTION: Mastoidectomy with removal of cochlear implant...

HYPOTHESIS: A tissue response in the form of foreign body or a hypersensitivity reaction to cochlear implantation is common and may be one possible cause of a soft failure of cochlear implantation. BACKGROUND: After a successful cochlear implantation, delayed failure may occur. The causes of a "soft" failure, that is, one in which device malfunction cannot be proven, are unknown. METHODS: The histopathology of the temporal bones of a patient who, in life, had experienced a soft failure after cochlear implantation was described...

BACKGROUND: Femtosecond (fs) laser pulses have recently received wide interest as an alternative tool for manipulating living biological systems. In various model organisms the excision of cellular components and the intracellular delivery of foreign exogenous materials have been reported. However, the effect of the applied fs laser pulses on cell viability and development has yet to be determined. Using the zebrafish (Danio rerio) as our animal model system, we address both the short- and long-term developmental changes following laser surgery on zebrafish embryonic cells...

STUDY DESIGN: A retrospective surgical case review. SETTING: A tertiary-care, university teaching hospital. PATIENTS: The authors describe a unique case operated on for a middle ear cholesterol granuloma, which had invaded the cochlea and vestibule causing profound sensorineural deafness. INTERVENTIONS: Extended radical mastoidectomy and labyrinthectomy with musculofascial seal. RESULTS: Successful postoperative outcome with no recurrence seen after 2 years of follow up...

Otoscopic evaluation of the external ear canal and tympanic membrane is the first diagnostic procedure that should be performed in animals presented with otitis externa. It is important to become familiar with the normal structures of the ear to identify any abnormalities. The video otoscope greatly enhances visualization of these structures as well as aiding in retrieval of foreign bodies, biopsy of masses, and performance of a myringotomy. In some cases, a complete otoscopic examination is not possible on the first visit, and the animal may require anti-inflammatory medications or otic flushing to visualize the entire ear canal as well as the tympanic membrane...

This is a case report of a 55 years-old Nigerian woman who presented an unusual left ear foreign body consisting of cyanoacrylate (super glue) which was successfully removed after application of acetone.

OBJECTIVE: To analyze the causes for residual or recurrent conductive hearing loss following stapedectomy or stapedotomy and then propose surgical techniques to avoid these complications. STUDY DESIGN: Prospective study of 279 consecutive stapedectomy or stapedotomy revisions performed by the author. SETTING: Tertiary referral center. PATIENTS: The study included 260 patients who presented with a 20 dB or greater average air-bone gap in the speech frequencies 1 month to 35 years following stapedectomy or stapedotomy (19 patients were explored for possible oval window perilymph fistula)...

LIM homeodomain genes have been involved in patterning in a variety of organisms. I have analyzed the expression of lmx1 during early ear development and explored its regulation by the neuroectoderm. Experiments were carried out on chick embryos. During early somitic stages (4-6 somites), lmx1 was expressed in the neural tube and in a stripe of the dorsal ectoderm. The ectodermal expression domain was then restricted to the otic placode (7-10 somites). At otic cup stages, lmx1 was downregulated in ventral and medial aspects of the otic epithelium facing the neural tube...

Foreign bodies in the ear occasionally thwart conventional means of removal. Styrofoam can be particularly problematic because it can be compressed and become tightly impacted in an ear canal. Furthermore, Styrofoam is friable and tends to fragment with usual removal methods. We report the case of a 6-year-old girl who was referred from another tertiary care hospital after failed efforts to remove a painfully impacted piece of Styrofoam from her left ear canal. Instillation of the organic solvent acetone into the ear canal was well tolerated and caused rapid and near-complete dissolution of the Styrofoam impaction...

An autologous free skin graft taken from the upper or the lower external ear canal or the auricle was implanted in the otic bulla of 28 guinea pigs. An epidermal cyst simulating middle ear cholesteatoma was successfully produced in 25 (89.3%) animals 8 weeks after grafting. Using this model, the histological reaction of middle ear granulation tissue to the debris was studied. Cysts originated from the auricular skin showed the strongest activity with regard to growth rate, amount of debris produced, and inflammatory reaction to the exposed debris...

A series of cases involving button batteries lodged in the ear or nasal cavity is presented. All produced tissue destruction. Injuries were generally severe, and included tympanic membrane perforation (three patients) or total destruction (three), marked necrosis of dermis of the external ear canal with exposed bone (seven), documented further impairment of hearing (three), destruction of ossicles (two), facial nerve paralysis and chondritis (one), nasal septal perforation (one), and superficial burns of nasal mucosa (one)...

The epithelium lining the inner ear contains a large number of differentiated cell types, arranged in precise patterns. Once the otocyst has closed, do the cells differentiate according to mechanisms intrinsic to the epithelium or are they dependent on external influences? In particular, are they governed by signals from the surrounding periotic mesenchyme? And is the closed structure of the inner ear or the otocyst fluid that it contains important for pattern formation and differentiation as it is for adult function? We have examined these questions by two types of grafting experiment...

Eleven cases of thermal otic injury are reviewed. The final outcome of therapy, whether medical or surgical is poor--only two of 11 patients were restored to normal. The possible pathogenesis of failure is discussed. Most cases could have been prevented by wearing ear plugs.
