Sudden hearing loss caused by labyrinthine hemorrhage

Sudden sensorineural hearing loss is relatively frequent. In most cases, the etiology is not discovered. One of the possible causes for sudden deafness is inner labyrinth bleeding, which was difficult to diagnose before the advent of magnetic resonance imaging. The purpose of this paper is to report a case of sudden hearing loss caused by a labyrinthine hemorrhage, and to present a review of the literature on this topic.

Surdez súbita causada por hemorragia intralabiríntica

A surdez subita sensorioneural e uma perda auditiva subita ou rapidamente progressiva. Na maioria dos casos a etiologia nao e descoberta. Uma das causas possiveis de surdez subita e a hemorragia intralabirintica que, antes do surgimento da ressonância magnetica, nao era corretamente diagnosticada. O objetivo deste trabalho e relatar um caso de surdez subita causada por hemorragia intralabirintica e realizar uma revisao da literatura sobre este assunto.

Bilateral inverted papilloma: case report and literature review.

The inverted papilloma is an uncommon unilateral nasosinusal benign tumor. The clinical picture presents nonspecific signs and symptoms, such as unilateral nasal obstruction, anosmia and headache. The diagnosis is established by anamnesis, physical exam, computed tomography and magnetic resonance imaging. Treatment is essentially surgical. This report has the objective of presenting an uncommon bilateral inverted nasal papilloma and making a literature review.

Mucocele frontoetmoidal: relato de casos e revisão da literatura

As mucoceles dos seios paranasais sao lesoes cisticas de revestimento epitelial com conteudo mucoide, que apresentam crescimento lento com caracteristicas expansivas e de reabsorcao ossea. Eventualmente, podem comprometer as estruturas nobres adjacentes como a orbita e a cavidade intracraniana. Acredita-se que sua etiologia esteja ligada a obstrucao do ostio de drenagem do seio paranasal envolvido. Podem causar dor facial, cefaleia, obstrucao nasal, diplopia, diminuicao da acuidade visual, deslocamento do globo ocular, edema facial ou ate mesmo meningite, dependendo da area anatomica comprometida. Acomete mais frequentemente os seios frontal e etmoidal anterior, sem prevalencia de sexo. O diagnostico e realizado atraves de exames de imagem, sendo a tomografia computadorizada o exame de eleicao, embora em algumas ocasioes a ressonância magnetica esteja indicada. Atualmente a abordagem endoscopica paranasal e o acesso cirurgico de primeira escolha, por ser menos invasiva e apresentar menor morbidade. Este estudo relata dois casos de mucocele frontoetmoidal com extensao orbitaria, abordados por via endoscopica endonasal. Os resultados comprovaram a seguranca e eficiencia deste acesso cirurgico.

Pediatric otosclerosis: case report and literature review.

Otospongiosis is an osteodystrophy of the temporal bone, characterized by disordered neoformation and deposition of bone, characterized by the presence of a progressive conductive, sensorineural or mixed hearing loss and tinnitus. Typically, otospongiosis presents as a slowly progressive conductive hearing loss in the third to fourth decade of life. Uncommonly children and adolescents may also have conductive or sensorineural hearing loss caused by otosclerosis. We describe a case of an 11-year-old patient, with progressive unilateral conductive hearing loss for 5 years. The otoscopic examination revealed a positive Schwartzs sign in the left ear. Audiometry, impedanciometry and CT scan showed characteristics that suggested otospongiosis. We reviewed clinical aspects, diagnosis and the therapeutic approach for otospongiosis in children.

Síndrome de Morquio: relato de caso e revisão da literatura

INTRODUCTION: Morquios Syndrome is a mucopolysaccharidosis type IV commomnly associated with auditive deficiency, although this association is not well described yet. OBJECTIVE: To evaluate the finding of auditive deficiency in a patient with Morquios Syndrome. METHODS: We describe the case of a 16-year-old male patient, with the diagnosis of Morquios Syndrome, that underwent physical examination and audiometric evaluation to determine the auditive loss. RESULTS: The patient had a history of skeletal complaints and since he was 2 years old. His parents were related and there was a positive family history for the same findings. For the last five years he has been complaining of progressive auditive loss. He had a typical appearence and weighted 27 Kg, with a stature of 99 cm, short neck, globous thorax and abdomen, genu valgum and wrists hyperextension. Otoscopy showed bilateral opacification of the ear drums and audiometry revealed mild conductive disacusis. DISCUSSION: Mucopolysaccharidosis (MPS) are caused by the deficiency of liposomal enzymes, leading to progressive accumulation of mucopolysaccharhides into the tissues. Morquios Syndrome is a MPS type IV inherited in a autosomic recessive pattern. Tissue deposits may occur into the visceral organs, bones, cornea and ears leading to structural and functional abnormalities. CONCLUSIONS: Morquios Syndrome is a metabolic disease of carbohydrates usually beginning between 18 and 24 months with a variable range of clinical findings. It is important to make the diagnosis early in order to avoid the limitations of the sensory losses.

Pericondrite por piercing: relato de casos e revisão da literatura

Auricular perichondritis is a complication related to ear piercing, caused by the hypersensitivity to nickel. The diagnosis is essentially based on clinical findings. The most pathogen frequently involved is Pseudomonas aeruginosa. Culture is important to determine the antibiotic susceptibility. We report 3 cases of ear piercing associated perichondritis and present a literature review.
