[Clinical analysis of 22 cases with parotid gland duct injury].

Purpose: To discuss the early diagnosis and treatment of injury to the parotid duct.

Methods: Segmental epidural catheter was used to repair the injured parotid duct, if the broken ends of the parotid duct can't be anastomized end to end, facial vein transplantation and fascia parotideomasseterica flap were used for reconstruction.

Results: In 22 cases, one case was lost to follow-up, nineteen cases had successful reconstruction of the parotid duct with good parotid secretions. Two cases had atrophy of the parotid gland.

Conclusions: Early diagnosis is critical for treatment of injury of parotid duct. The efficacy of segmental epidural catheter is excellent for repair of parotid duct defect.
