Advances in nasal endoscopy have broadened the indications of endoscopic surgery to nose-related areas, and it has recently become more common to treat diseases in related fields such as neurosurgery or ophthalmology, endoscopically.
In this report we describe endoscopic bath plug closure and endoscopic dacryocystorhinostomy as means of treating cerebrospinal fluid leaks and nasolacrimal duct obstruction, respectively. In the bath plug closure procedure, fat tissue tied with sutures is packed into the dural perforation, and is then drawn back with adequate tension to achieve complete closure. In the endoscopic dacryocystorhinostomy procedure, the lacrimal sac with surrounding bone is opened endoscopically in nasal cavity, and a silicone tube is then inserted and mitomycin-C is applied in and around the lacrimal sac. These procedures are less traumatic than conventional procedures. To optimize the results, it is fairly important and advisable to discuss the case and cooperate with neurosurgeons and ophthalmologists before and during the operation, in addition to having sufficient anatomical and physiological knowledge of diseases in related fields.
