Nose sinus manometry in evaluating functional outcomes of anterior and posterior endoscopic dacryocystorhinostomy.

OBJECTIVE: The aim of this study is to evaluate the effectiveness of anterior and posterior dacryorhinocystostomy (En-Dcr) by assessing the surgical outcome with a new objective technique, nose sinus manometry. MATERIALS AND METHODS: Thirty adult patients presenting nasolacrimal duct obstruction were enrolled in this study and randomly divided in two groups. In group A patients underwent anterior endonasal dacryorhinocystostomy, group B underwent the posterior approach. All patients were evaluated through Nose Sinus Manometry, endoscopic dye disappearance functional test (EDFT) and subjective assessment three months post-op. Pearson test and T-student Test were used for evaluations. RESULTS: The mean differences in the pressure values were significantly different in the two groups of treatment, therefore, the patients of group B had strong improvement in pressure values compared with patients of group A. CONCLUSION: This study confirms a relevant physical distinction between posterior En-Dcr outcomes compared to anterior En-Dcr and reveals a significant success rate difference between the two groups of patients. The posterior surgical technique shows better results than the anterior one, by providing an almost physiological post- operative endonasal outcome. These results also showed the effectiveness of Nose Sinus Manometry in assessing the post- operative outcomes after En-Dcr.

Antecedentes y objetivo: El objetivo de este estudio es evaluar la efectividad de la dacriocistorrinostomía anterior y posterior (En-Dcr) mediante la evaluación del resultado quirúrgico con una nueva técnica objetiva, la manometría del seno nasal.Materiales y métodosTreinta pacientes adultos que presentaban obstrucción del conducto nasolagrimal se inscribieron en este estudio y se dividieron al azar en dos grupos. En el grupo A, los pacientes se sometieron a dacriocistorrinostomía endonasal anterior, en el grupo B se sometió al abordaje posterior. Todos los pacientes fueron evaluados mediante manometría de seno nasal, prueba EDFT y evaluación subjetiva tres meses después de la operación. Análisis estadístico utilizado: la prueba de Pearson y la prueba t Student se utilizaron para las evaluaciones.ResultadosLas diferencias medias en los valores de presión fueron significativamente diferentes en los dos grupos de tratamiento, por lo tanto, los pacientes del grupo B tienen una fuerte mejora en los valores de presión en comparación con los pacientes del grupo A.ConclusionesEste estudio confirma una distinción física relevante entre los resultados posteriores de En-Dcr, en comparación con los anteriores En-Dcr, y revela una diferencia significativa en la tasa de éxito entre los dos grupos de pacientes. La técnica quirúrgica posterior muestra mejores resultados que la anterior, al proporcionar un resultado endonasal postoperatorio casi fisiológico. Estos resultados también mostraron la efectividad de la manometría de seno nasal para evaluar los resultados postoperatorios después de En-Dcr. (AU)

Magnetic resonance imaging in the pre-operative evaluation of obstructive epiphora: true-FISP and VIBE vs gadolinium.

PURPOSE: To assess unenhanced magnetic resonance imaging (MRI) in the preoperative evaluation of obstructive epiphora in patients undergoing dacryocystorhinostomy (DCR) and in particular, to evaluate the efficacy of this technique in the detection of the exact level of obstruction occurring in the naso-lachrymal duct (NLD). The correct identification and characterization of the NLD and its obstructions lead to a more effective surgery, preventing recurrent dacryocystitis after the surgical treatment. METHODS: From January 2009 to December 2014, 127 obstructive epiphoras were diagnosed and treated in 127 patients (35 M, 92 F; mean age 60.7 ± 7.48 years, range 42-75 years) with endoscopic DCR, in a IRB-approved protocol. To precisely define the morphology of the NLD and the site of obstruction, some of these patients (67/127) underwent unenhanced 1.5-T MR with TrueFISP and VIBE sequences, while the remaining (60/127) underwent Gadolinium-enhanced 1.5-T MR. Afterwards, surgery checked the real site of obstruction in both groups of patients (enhanced and unenhanced MR), with surgical outcomes matched with previous MR reports. RESULTS: In all cases, unenhanced MRI was able to detect the exact site of obstruction along the NLD, allowing a correct planning of surgical endoscopic procedures. On the contrary, enhanced MRI wrongly diagnosed six patients with proximal stenosis (6/60, 10.0%) as intermediate NLD obstruction. Unenhanced MRI was found to be more accurate than enhanced MRI with a statistical significant difference (p value = 0.0256) and obviously cheaper and easier to perform. All imaging reports were verified with surgery. The correct identification of the level of obstruction allowed successful surgery in around 73% (93/127) of patients, who had no recurrence during 6-month follow-up. CONCLUSION: In patients with epiphora, unenhanced MR showed to be highly reliable and even more effective than enhanced MR in the preoperative characterization of NLD stenosis, with no need of performing complex, time-wasting and expensive procedures for the administration of topical contrast media.

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. .

Fronto-turbinalis sinus expansion and headache.

Headaches of rhinogenic origin illustrate an interesting paradox. Little is known about their pathophysiology, mechanisms, and prevalence; yet, the concept that these headaches are of importance is widely accepted. This article discusses the relationship between fronto-turbinalis sinus expansion and headaches, as well as headache outcomes after surgical approach.
