[Experimental restoration of the patency of the efferent ducts of the salivary glands].

In order to introduce the microsurgical technique of suturing the salivary ducts' lesions, microsurgical anatomy of ducts draining large salivary glands was studied in 12 human autopsies and 10 dogs. Experimental surgery was performed in 10 dogs: the sectioned parotid and submandibular ducts were repaired. Sialographic evidence of recanalization was obtained in 8 of the dogs. Histological investigation showed minimal inflammatory response within 20 to 60 days after surgery.
