RESUMO
BACKGROUND AND OBJECTIVES: Traditional and well-established transcranial approaches to the spheno-orbital region and middle cranial fossa guarantee optimal intracranial exposure, and additional orbital and zygomatic osteotomies provide further control over extracranial components to be resected; however, these techniques come at the cost of additional morbidity. The introduction of minimally invasive endoscopic approaches and the conceptualization of the so-called "multiportal" paradigm might provide an alternative route. This preliminary study investigates the feasibility of the combined Biportal Endoscopic TransOrbital and transMaxillary Approach (bETOMA) approach to the spheno-orbital and middle cranial fossa regions. METHODS: Using 4 silicon-injected adult cadaver heads (8 sides; 16 approaches), we systematically dissected through superior eyelid ETOA and endoscopic TMA approaches. The analysis focused on pterygopalatine, infratemporal, anterior and middle cranial fossae, Meckel cave, and cavernous sinus access. We evaluated the feasibility of bETOMA using linear distances, angles of attack, and exposure areas. We also introduced volume of operative maneuverability, its standardized derivative (sVOM), target distance, visuo-operative angle, and working zone volume as novel metrics. RESULTS: The analysis revealed comparable angles of attack between approaches. ETOA and TMA exposure areas were 918.38 ± 223.93 mm2 and 257.07 ± 86.07 mm2, respectively. TMA showed a larger VOM in the greater sphenoid wing, but ETOA offered superior distal maneuverability (sVOM: 5.39 ± 1.94 vs 2.54 ± 0.79 cm3) and closer intracranial space access (27.45 vs 50.83 mm). The combined approaches yielded a mean working zone volume of 13.75 ± 3.73 cm3 in the spheno-orbital interface. CONCLUSION: The bETOMA approach provides adequate neurovascular exposure and maneuverability to the spheno-orbital region, infratemporal, and anterior and middle cranial fossae, addressing significant limitations of previously investigated monoportal techniques (ie, optic nerve decompression, hyperostotic bone resection, and infratemporal exposure). This combined minimally invasive approach might help manage lesions harbored within the cranio-orbital interface region invading the extracranial space.
RESUMO
Objective The purpose of this study was to evaluate pituitary tumor patient satisfaction with telemedicine, patient preference for telemedicine, potential socioeconomic benefit of telemedicine, and patients' willingness to proceed with surgery based on a telemedicine visit alone. Method In total, 134 patients who had pituitary surgery and a telemedicine visit during the coronavirus disease 2019 (COVID-19) pandemic (April 23, 2020-March 4, 2021) were called to participate in a 13-part questionnaire. Chi-square, ANOVA, and Wilcoxon Rank Sum tests were used to determine significance. Result Of 134 patients contacted, 90 responded (67%). Ninety-five percent were "satisfied" or "very satisfied" with their telemedicine visit, with 62% stating their visit was "the same" or "better" than previous in-person appointments. Eighty-two percent of the patients rated their telemedicine visit as "easy" or "very easy." On average, patients saved 150 minutes by using telemedicine compared with patient reported in-person visit times. Seventy-seven percent of patients reported the need to take off from work for in-person visits, compared with just 12% when using telemedicine. Forty-nine percent of patients preferred in-person visits, 34% preferred telemedicine, and 17% had no preference. Fifty percent of patients said they would feel comfortable proceeding with surgery based on a telemedicine visit alone. Patients with both initial evaluation and follow-up conducted via telemedicine were more likely to feel comfortable proceeding with surgery based on a telemedicine visit alone compared with patients who had only follow-up telemedicine visits ( p = 0.051). Conclusion Many patients are satisfied with telemedicine visits and feel comfortable proceeding with surgery based on a telemedicine visit alone. Telemedicine is an important adjunct to increase access to care at a Pituitary Center of Excellence.
