Suzuki, Motohiko; Nakamura, Yoshihisa; Yokota, Makoto; Ozaki, Shinya; Murakami, Shingo 2017-10-01 We previously reported a modified endoscopic medial maxillectomy (modified transnasal endoscopic medial maxillectomy through prelacrimal duct approach MTEMMPDA) to resect inverted papilloma (IP), for which the inferior turbinate (IT) and nasolacrimal duct (ND) can be preserved.
En 1994 el Presidente de la Republica de El Salvador Armando Calderon Sol invito al Ministerio de Educacion a integrar una comision de Educacion Ciencia y Desarrollo, con la finalidad de presentar liniamientos para enmarcar un proceso de transmision educativa en el pais.
MTEMMPDA is a safe and effective method to obtain wide, straight access to the maxillary sinus (MS). However, there are few reported cases of patients who underwent MTEMMPDA, and even fewer of patients who underwent partial osteotomy of the apertura piriformis and the anterior wall of the MS.
In this study, we analyzed the outcomes of 51 patients who underwent MTEMMPDA. Retrospective review. All patients who underwent MTEMMPDA at our hospital between January 2004 and December 2015 were included in this study. Fifty-one patients with sinonasal IP in the MS underwent MTEMMPDA.
Recurrence was seen in the MS of one patient (follow-up of 2-138 months). The IT remained unchanged in all 51 patients without atrophy. We have not observed epiphora, eye discharge, dry nose, or persistent crusting after this surgery. Although seven patients had numbness around the upper lip after surgery, this had disappeared by 1 year after surgery. Additional partial osteotomy of the apertura piriformis and the anterior wall of the MS were done in eight patients.
Deformation of the external nose was not seen. This approach appears to be a safe and effective method to resect IP in the MS, even if there is additional partial osteotomy of the apertura piriformis and the anterior wall of the MS.

Friedrich, D T; Sommer, F; Scheithauer, M O; Greve, J; Hoffmann, T K; Schuler, P J 2017-12-01 Objective Advanced transnasal sinus and skull base surgery remains a challenging discipline for head and neck surgeons. Restricted access and space for instrumentation can impede advanced interventions.
Thus, we present the combination of an innovative robotic endoscope guidance system and a specific endoscope with adjustable viewing angle to facilitate transnasal surgery in a human cadaver model. Materials and Methods The applicability of the robotic endoscope guidance system with custom foot pedal controller was tested for advanced transnasal surgery on a fresh frozen human cadaver head. Visualization was enabled using a commercially available endoscope with adjustable viewing angle (15-90 degrees). Results Visualization and instrumentation of all paranasal sinuses, including the anterior and middle skull base, were feasible with the presented setup. Controlling the robotic endoscope guidance system was effectively precise, and the adjustable endoscope lens extended the view in the surgical field without the common change of fixed viewing angle endoscopes. Conclusion The combination of a robotic endoscope guidance system and an advanced endoscope with adjustable viewing angle enables bimanual surgery in transnasal interventions of the paranasal sinuses and the anterior skull base in a human cadaver model. The adjustable lens allows for the abandonment of fixed-angle endoscopes, saving time and resources, without reducing the quality of imaging.
Mitsuyo Mieda 2018-05-01 Full Text Available Transnasal endoscopy is widely used in screening for upper gastrointestinal lesions because of less associated pain. Nasal bleeding is the most severe adverse effect, but specific risk factors have not been identified.
The aim of this study is to identify risk factors for nasal bleeding during transnasal endoscopy. Nasal bleeding occurred in 160/3035 (5.3% of patients undergoing transnasal endoscopy as part of health checkups. Patient data were retrospectively evaluated including anthropometric, medical, and life-style parameters with multiple logistic regression analysis.
Multiple logistic regression revealed that nasal bleeding was significantly associated with age in decades odds ratio/10 years 0.78, 95% confidence interval (CI 0.63–0.97, p = 0.027, female gender (2.15, 95% CI 1.48–3.12, p.
