Examining the benefits and risks of using an intranasal local anesthetic for nasal endoscopy: a review of literature

Cooper, Chanielle 26 January 2024 (has links)
The utilization of intranasal local anesthetic agents has become a prevalent approach in nasal endoscopy procedures, aimed at enhancing patient comfort and optimizing procedural outcomes. This comprehensive literature review seeks to evaluate the benefits and risks associated with the use of intranasal anesthetics prior to nasal endoscopy. A total of twenty-eight studies published within the last three decades were meticulously examined and incorporated in this literature review. The majority of the reviewed studies overwhelmingly demonstrated no significant reduction in patient discomfort or pain during nasal endoscopy with the use of intranasal anesthetics. However, it is noteworthy that two of the included studies highlighted the potential benefits of masking agents to mitigate the bitter taste associated with anesthetic agents, leading to increased analgesic properties during the endoscopic procedure. Conversely, three of the reviewed studies indicated that intranasal anesthetic usage positively impacted the ease of the procedure for the endoscopist, resulting in improved visualization of the nasal cavity and higher-quality images. Interestingly, the choice of specific anesthetic agents, such as cocaine, tetracaine, lidocaine, or co-phenylcaine, did not appear to play a substantial role in the reported outcomes across the studies. In contrast, the method, timing, and decision-making process regarding the application of intranasal anesthetics emerged as crucial factors that influenced the observed outcomes and potential side effects. The variations in these factors yielded diverse results among the studies, emphasizing the significance of careful consideration and standardized protocols in the administration of intranasal anesthetics. Overall, while the reviewed studies generally did not demonstrate significant benefits in terms of reducing patient discomfort or pain, there were notable improvements in the ease of procedure for the endoscopist with intranasal anesthetic usage. Furthermore, the choice of anesthetic agent alone did not significantly impact the outcomes. However, the methodology, timing, and decision-making were shown to be important factors in achieving desirable results. Further research is warranted to explore optimal approaches for intranasal anesthetic administration, including the development of effective masking agents and standardized protocols. It is crucial for further research to assess the utilization of intranasal anesthetics to ensure patient comfort, procedural efficacy, and safety during nasal endoscopy procedures.

No. of bitstreams: 1 Dissertação marcelo-sec.pdf: 542785 bytes, checksum: a79f804abd3185cbf4a93f637e7b233a (MD5) Previous issue date: 2005 / A hipertrofia de adenóide promove uma diminuição do espaço livre da nasofaringe e se constitui em uma das principais causas da respiração bucal. Entre os métodos utilizados para o diagnóstico desta condição, os mais precisos são a endoscopia nasal e a ressonância magnética, por permitirem a visualização da nasofaringe em três dimensões. No entanto, o método mais utilizado, em Odontologia, é a radiografia cefalométrica lateral. Torna-se, portanto, de grande importância, a verificação da eficiência deste método de diagnóstico. Este trabalho foi realizado com o objetivo de determinar a eficácia da radiografia cefalométrica lateral no diagnóstico da hipertrofia de adenóide, pela comparação deste método com a endoscopia nasal. Foram avaliados 30 indivíduos (7 a 12 anos) sem história prévia de cirurgia otorrinolaringológica. Todos fizeram um exame de endoscopia nasal e uma radiografia cefalométrica lateral. Nas endoscopias, foi registrada a porcentagem de obstrução da nasofaringe, e nas radiografias, a menor dimensão ântero-posterior livre da nasofaringe. Os valores encontrados pelos dois exames se mostraram fortemente correlacionados (r = ? 0,793, p-valor < 0,01). Em seguida, foram realizados os testes de validade e confiabilidade para o diagnóstico radiográfico. Para isso, foram considerados portadores de hipertrofia severa de adenóide, os pacientes que apresentaram, na endoscopia, obstrução da nasofaringe igual ou superior a 75% e, nas radiografias, o menor diâmetro antero-posterior da nasofaringe igual ou inferior a 5 mm. O exame radiográfico teve uma sensibilidade de 75%, especificidade de 86,3%, valor preditivo positivo de 66,7%, valor preditivo negativo de 90,4% e a exatidão foi de 83,3%. A radiografia cefalométrica lateral, então, se mostrou um exame eficiente para o diagnóstico da hipertrofia de adenóide, o que foi comprovado pela forte correlação entre os seus resultados e os da endoscopia nasal, que é considerado o exame padrão-ouro para o diagnóstico desta condição. / Salvador

CORRELAÇÃO ENTRE A NASOFIBROFARINGOSCOPIA E A CEFALOMETRIA NO DIAGNÓSTICO DE HIPERPLASIA DE TONSILAS FARÍNGEAS / CORRELATION BETWEEN NASOPHARYNGOSCOPY AND CEPHALOMETRY IN THE DIAGNOSIS OF HYPERPLASIA OF PHARYNGEAL TONSILS

Ritzel, Rodrigo Agne 01 March 2011 (has links)
Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth breathing. The accurate diagnosis of this alteration is important for proper therapeutic planning. As a consequence, studies have been developed in order to provide information about the procedures that can be used for the diagnosis of pharyngeal obstruction. Objective: Verify the correlation between nasopharyngoscopy and cephalometric exams in the diagnosis of pharyngeal tonsil hyperplasia. Material and Methods: 55 children took part in this study, 30 girls and 25 boys, aged between seven and 11. The children were submitted to nasofibropharyngoscopic and cephalometric evaluation to determine the grade of nasopharyngeal obstruction. The Spearman's rank correlation coefficient at the 5% significance level was used to verify the correlation of these exams. Results: In nasopharyngoscopy, most children showed hyperplasia of the pharyngeal tonsil grades 2 and 3, followed by grade1. In cephalometry, most children showed hyperplasia of the pharyngeal tonsil grade 1, followed by grade 2. A regular positive correlation was observed in the correlation between the exams. Conclusion: It was concluded that the evaluation of the pharyngeal tonsil hyperplasia can be carried out by fiberoptic nasopharyngoscopy and cephalometry, as these examinations present a regular positive relation. However, it was found that cephalometry tends to underestimate the size of the pharyngeal tonsil in relation to nasopharyngoscopy. / A hiperplasia de tonsila faríngea é uma das principais causas de respiração oral. O diagnóstico preciso desta alteração é importante para o correto planejamento terapêutico. Em vista disso, estudos têm sido desenvolvidos a fim de fornecer subsídios quanto aos procedimentos que podem ser utilizados para o diagnóstico de obstrução faríngea. Objetivo: Verificar a correlação entre os exames de nasofibrofaringoscopia e cefalometria no diagnóstico de hiperplasia de tonsila faríngea. Material e Métodos: Participaram deste estudo 55 crianças, 30 meninas e 25 meninos, com idades entre sete e 11 anos. As crianças foram submetidas à avaliação nasofibrofaringoscópica e cefalométrica para a determinação do grau de obstrução da nasofaringe. Para verificar a correlação entre esses exames foi utilizado o coeficiente de correlação de Spearman ao nível de significância de 5%. Resultados: Na nasofibrofaringoscopia a maioria das crianças apresentou hiperplasia de tonsila faríngea graus 2 e 3, seguidas de grau 1. Na cefalometria a maior parte das crianças apresentou hiperplasia de tonsilas faríngeas grau 1, seguida de grau 2. Na correlação entre os exames, evidenciou-se correlação regular e positiva. Conclusão: A avaliação da hiperplasia de tonsilas faríngeas pode ser realizada pela nasofibrofaringoscopia e pela cefalometria, pois estes exames apresentam uma relação regular e positiva. No entanto, verificou-se que a cefalometria tende a subestimar o tamanho da tonsila faríngea em relação à nasofibrofaringoscopia.
