The otolaryngologist plays a fundamental role in the prognosis of NKTLN and can shorten time between symptom onset and treatment of the patient.

A displasia fibrosa é lesão pseudo-neoplásica de etiologia desconhecida, caráter benigno e recidivante, caracterizada pelo desenvolvimento de tecido fibroso e traves osteóides que substituem gradualmente o osso normal. O principal diagnóstico diferencial da forma monostótica, no envolvimento dos ossos da cabeça e pescoço, é o fibroma ossificante, que alguns consideram variante desta entidade. Esse trabalho tem como objetivo revisar as principais características clínicas, radiológicas e histopatológicas que auxiliam no diagnóstico diferencial da displasia fibrosa com o fibroma ossificante e discutir o comportamento recidivante da displasia fibrosa, essencial ao planejamento cirúrgico. Relatamos três casos provenientes do ambulatório de Otorrinolaringologia da Santa Casa de Misericórdia de São Paulo, avaliados quanto às queixas, exame físico, achados de imagem e tratamentos. Nos três casos o diagnóstico foi confirmado pelo exame anatomopatológico. Todos apresentaram recidiva após a ressecção cirúrgica, diagnosticada entre o primeiro e o oitavo ano de seguimento. Devido ao comportamento clínico semelhante da displasia fibrosa e do fibroma ossificante, o exame anatomopatológico é essencial para o diagnóstico diferencial. O acompanhamento clínico permanente desses pacientes é necessário para que as possíveis recidivas sejam diagnosticadas precocemente.

Summary Introduction: Extramedullary plasmacytoma is a plasma cell tumor that grows within any of the soft tissues of the organism. Similar to all plasmacytic dyscrasia, the disease is extremely rare. Aim: This study reports a case of an extramedullary plasmacytoma of the nasal cavity and provides a literature review on the topic. Case report: A 51-year-old woman presented at our tertiary university hospital with a 6-month history of progressive nasal obstruction, predominantly to the right side, and self-limiting epistaxis. Examination revealed a large pale-reddish tumor within the right nasal cavity. Anatomopathological analysis showed features consistent with a plasmacytoma diagnosis, which was subsequently confirmed by immunohistochemical techniques. Further assessment revealed the solitary nature of the condition, consistent with extramedullary plasmacytoma. Radiotherapy was initiated, which led to partial regression of the symptoms. The tumor was surgically removed by using a mid-facial degloving approach. The patient evolved with a naso-oral fistula and underwent 3 corrective surgeries. No evidence of associated systemic disease was found after 5 years of follow-up. Conclusions: This case report, which describes a rare tumor of the nasal cavity, is expected to improve the recognition and referral of this condition by ear, nose, and throat (ENT) specialists for multidisciplinary management and long-term follow-up.

Purpose: To culturally adapt the Family Quality of Life Scale to the Brazilian Portuguese version and evaluate the instrument reliability and family quality of life of those who have children with hearing loss. Methods:The process of cultural adaptation of the scale followed the steps of the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measure. It was conducted in three stages: translation, back translation, and application in a pilot sample, as a way to check the comprehension difficulties of the items. After it had been completed, it was administered to 41 families who have children with hearing loss and, with their results, the quality of life and reliability were analyzed based on the Cronbach's alpha statistical test. Results:In the first version (translation), among the 25 items, there were differences between the translators only in four items; after the corrections, the second version was done (back translation), in which other four more differences were found. Finally, after the final corrections, the last version was developed and used in the pilot sample without differences. Thus, it was applied to families with deaf children, who believe to be satisfied as to their quality of life. The Cronbach's alpha test found that the scale shows a satisfactory reliability. Self-Report Measure. Realizada em três momentos: tradução, retrotradução e aplicação na amostra piloto como forma de verificar dificuldades de compreensão dos itens. Quando finalizada foi aplicada em 41 famílias que possuem filhos com deficiência auditiva e, com os seus resultados, foram analisadas a qualidade de vida (QV) e a confiabilidade, a partir do teste estatístico alfa de Cronbach (α). Resultados: Na primeira versão (tradução), dentre os 25 itens presentes, apenas em 4 houve divergências entre as tradutoras; após as correções, houve a segunda versão (retrotradução), em que foram identificadas mais 4 divergências. Por fim, após as correções finais, a última versão foi elaborada e usada na amostra piloto sem divergências, e, dessa forma, foi aplicada nas famílias de filhos surdos, as quais se consideraram satisfeitas em relação à QV. Com o teste alfa de Cronbach (α) foi verificado que a escala tem confiabilidade satisfatória. Conclusão: A versão em PB da FQOLS é um instrumento de fácil aplicação e com confiabilidade satisfatória. As famílias estão satisfeitas com sua QVF. Conclusion

Summary Introduction: Paragangliomas are neuroendocrine tumors that most commonly originate in the adrenal gland, a type that is called pheochromocytoma; however, 5–10% of paragangliomas are extra-adrenal and may arise in any area between the neck and pelvic region along the sympathetic nervous system. Those located in the head and neck comprise 3% of extra-adrenal tumors, with the majority originating in the tympanic–jugular region and carotid body. Objective: To present a rare case of nasal paraganglioma and review the literature. Case report: The patient was submitted to medial subtotal maxillectomy, and her clinical findings, diagnostic data, and treatment outcome were recorded. Conclusion: Paragangliomas are considered benign tumors, but they occasionally display a malignant character. The most important finding in this case was the need for total resection of the tumor to avoid recurrence.
