The management of early stage NSCLC during the COVID-19 pandemic should be balanced with available hospital resources, risk of progression of disease, risk of transmission of COVID-19 to patient and surgeon, and the availability of alternative therapies. This article will address the current challenges with treating early stage NSCLC during the COVID-19 pandemic and provide a clinical framework for providing effective surgical therapy while mitigating the risk of transmission of the SARS-CoV-2 virus to patients and surgeons. In this study we have based our research on botulinium toxin injection via targeted neuromuscular end plate zones, specifically in muscles with diffuse distribution of the latter. The muscular surface anatomical variety was also taken into consideration with thorough pre-injection examination of every subject. With consideration of the facial muscles anatomical variation and neuromuscular bundle distribution, we have applied the method of retrograde botulinium toxin injection on a series of 10 patients on the right side of the face with the left side as a control side, it was injected in a regular perpendicular manner in order to conclude the efficacy of targeted motor end zone injection. Using an auto-injecting syringe, we have delivered 6 Allergan units per zone (frontalis, glabellar lines of corrugator supercilii and orbicularis oculi crow's feet). On control day 8 we have noticed a more prominent effect mainly on the level of the orbicularis oculi muscle and the corrugator supercilii muscle on 9 outnjection sites and hence pain, the use of lower dosage and hence treatment cost, as well as lowering the unwanted product dissemination to the neighboring mimic muscles.Defects around the knee exhibit various etiologies and pose challenges to both ortho
