ABSTRACT
Epiphora from monocanalicular obstruction is commonly treated with canaliculoplasty, with or without dacryocystorhinostomy, or with conjunctivodacryocystorhinostomy with Jones tube placement. We describe two patients with epiphora due to isolated monocanalicular obstruction without concurrent nasolacrimal duct obstruction who underwent endoscopic dacryocystorhinostomy; both cases had previously failed canaliculoplasty, and both reported significant improvement in epiphora postoperatively. We hypothesize this is due to decreased resistance through the lacrimal drainage system allowing for increased flow through the patent canaliculus and shortened lacrimal apparatus. In patients presenting with epiphora secondary to isolated monocanalicular obstruction, endoscopic dacryocystorhinostomy may be considered in the absence of nasolacrimal duct obstruction before proceeding to conjunctivodacryocystorhinostomy and Jones tube placement.

Myxofibrosarcoma is rarely found in the orbit, let alone as a primary orbital tumor. With this having only been previously reported 5 times in the literature, there is a very limited understanding of its presentation and course. Typical management involves surgical excision with or without postoperative radiotherapy. Low-grade malignancy, although rare to metastasize, still has a high rate of local recurrence and with each recurrence increases the risk of metastatic potential. With this in mind, analysis of each case is critical in better understanding the disease, and this case adds to the current literature.
