Endoscopic sinus surgery in individuals with facial pain due to chronic maxillary sinusitis ? a functional controlled study / Cirurgia endoscópica de seio da face em indivíduos com dor facial devida a sinusite maxilar crônica ? um estudo funcional controlado

Objective: To measure the intra-sinus pressure and the maxillary sinus functional efficiency (MSFE) in individuals with chronic facial pain after conservative or conventional endoscopic maxillary surgery, as well as in controls. Method: Sinus manometry was performed 5 times during inhalation. Results: The resemblance of pressure values comparing those treated with minimally invasive surgery and controls was remarkable, while traditional surgery significantly decreased intrasinusal pressures. The MSFE was 100% in the three tested times for controls, close to that in those submitted to minimally invasive surgery (98.3%, 98.8%, and 98.0%) and significantly impaired after conventional surgery (48.8%, 52.1%, 48.5 %, p<0.01). All patients submitted to minimally invasive surgery remained pain-free after three months of surgery, relative to 46.7% of the submitted to conventional surgery (p<0.05). Conclusion: Minimally invasive sinus surgery is associated with functionality of the chambers that resemble what is found in normal individuals. .

Objetivo: Medir a pressão intrasinusal e a eficiência funcional do seio maxilar (EFSM) em indivíduos com dor facial crônica após cirurgia endoscópica maxilar conservadora ou convencional em comparação a pessoas normais. Método: A manometria do seio foi feita 5 vezes durante a inalação. Resultados: A semelhança entre os valores das pressões comparando aqueles tratados com cirurgia minimamente invasiva e os controles foi notável, enquanto que na cirurgia tradicional houve diminuição significativa das pressões intrasinusais. A EFSM foi 100% nas três vezes testadas nos controles, de modo muito semelhante ao que foi observado naqueles submetidos a cirurgia minimamente invasiva (98,3%, 98,8%, e 98,0%) e significativamente diminuída naqueles submetidos a cirurgia convencional (48,8%, 52,1%, 48,5 %, p<0,01). Todos os pacientes submetidos a cirurgia minimamente invasiva mantiveram-se sem dor três meses depois da cirurgia, comparados a 46,7% naqueles submetidos a cirurgia convencional (p<0,05). Conclusão: Cirurgia minimamente invasiva está associada a funcionalidade das câmaras sinusais que se assemelha ao que é observado em indivíduos normais. .

Recirculación en rinosinusitis maxilar / Mucus recirculation in maxillary rhinosinusitis

Introducción: La recirculación de moco entre el ostium natural del seno maxilar y otras aberturas en el seno, altera el transporte mucociliar normal, favorece su acumula-ción y sobreinfección, perpetuando el fenómeno inflamatorio. Objetivo: Describir nuestra experiencia en el diagnóstico y tratamiento de pacientes con rinosinusitis maxilar crónica y/o aguda recurrente cuyo estudio reveló recirculación maxilar. Material y método: Estudio retrospectivo descriptivo. Se revisaron historias clínicas, nasofibroscopías, informes radiológicos y hallazgos operatorios. Resultados: Ocho pacientes con edad promedio de 43 años. El 100%% presentó antecedente de cirugía que involucraba el seno maxilar. Todos se presentaron como rinosinusitis maxilar crónica y/o aguda con reagudizaciones frecuentes (3 episodios/ año). El diagnóstico se realizó mediante nasofibroscopía que evidenció recirculación de moco entre ostium natural y accesorio. Cinco pacientes se sometieron a cirugía endoscópica para unir el ostium accesorio (OA) al natural, disminuyendo el número de exacerbaciones. Conclusión: La recirculación maxilar se debe sospechar en pacientes con diagnóstico de rinosinusitis maxilar crónica y/o aguda recurrente con antecedente de cirugías que involucren el seno maxilar. Su diagnóstico se basa en la observación de recirculación de moco a la nasofibroscopía. El manejo es quirúrgico y dependerá de la ubicación del OA y de la permeabilidad del ostium natural.

Introduction: Recirculation of mucus between the maxillary sinus natural ostium and adjacent openings disturbs mucociliary clearence leading to secretions accumulation and persistent infection, perpetuating the inflammatory phenomenon. Aim: Describe our experience in the diagnosis and treatment ofpatients with maxillary rhinosinusitis (chronic or acute recurrent) and maxillary recirculation. Material and method: Descriptive and retrospective study. Clinical records, radiologic characteristic, nasal endoscopies and surgical findings were reviewed. Results: 8 patients, mean age of 43 years. All of them had prior history of maxillary sinus surgery. Clinical presentation was maxillary rhinosinusitis, chronic or acute, with frequent episodes ofreagudization (3 episodes/year). The diagnosis was made by endoscopic nasal examination that showed mucus recirculation between natural and accessory ostium. Endoscopic sinus surgery was done in 5patients in order to communicate the accessory to the natural ostium, leading to a decrease in the number of exacerbations. Conclusions: Maxillary recirculation must be suspected in patients with maxillary rhinosinusitis (chronic or acute recurrent) who have had prior surgical procedures that involve the maxillary sinus. The diagnosis is based on the observation of the recirculation phenomenon in the nasal endoscopy. The treatment is surgical and depends on the location of the accessory ostium and the permeability of the natural ostium.

Sinusitis en Pediatria / Sinusitis in Pediatry

Se describen 54 ninos con sinusitis, 34 ninas y varones, la edad promedio de presentacion fue 6.5 anos. Las manifestaciones clinicas mas frecuentes fueron la rinorrea y/o tos recurrente. El 91 por ciento presento sinusitis maxilar. Enfermedades asociadas en forma importante fueron la otitis media a repeticion tonsilofaringitis, e hipertrofia de adenoides. Recomendamos sospechar la entidad en ninos que presentan los sintomas descritos. Todos fueron tratados con antibioticos, antialergico oral o corticoide topico, 27 pacientes mejoraron, 21 permanecen igual, uno se curo y 3 desaparecieron del seguimiento.
