title: A method for combined dacryocystorhinostomy with external ethmoidectomy.
abstract: Severe polypoid rhinosinusitis requiring external ethmoid surgery may be seen in conjunction with partial or complete nasolacrimal obstruction. When this obstruction is associated with persistent, unresolved lacrimal symptoms, it is sometimes appropriate to combine surgical procedures, thereby avoiding separate lacrimal surgery. A method combining dacryocystorhinostomy (DCR) with external ethmoidectomy is described. The anatomy involved in this procedure and the indications for it are discussed.
