Abstract:

Objective    To explore a proper endoscopic surgery for maxillary sinus(MS) lesion and to decrease the recurrence after operation. Methods    Since January 1999,  sixtynine cases had been operated upon and followed up for 1 to 9 years(average 4.5years) .After a tube was implanted through the lacrimal passages,the lesion was removed by using XPS3000. The majority of the inner wall of MS was  removed. The bony attachment of the tumor and neighbor tissues were resected by an electric scalpel.    Results    Recurrence was identified in one case (1.45%).The small mass of the lesion had recurrence but was completely removed. One patient with lymphoma died of metastasis within a half year after surgery. All of them had no epiphora and other complications. Conclusion    When appropriate indications are selected, endoscopic surgical technique in combination with lacrimal passage implantation of a tube is proved to be a good method in treating maxillary sinus lesion.
