A novel transcondylar approach combined with posterior disc attachment release for neoplasms near temporomandibular joint

Abstract

Abstract: PURPOSE: To introduce a novel transcondylar approach and discuss its indications, surgical procedures and preliminary clinical effects. METHODS: The novel approach was used in 5 cases from January 2006 to December 2014. The common characteristics of the 5 masses were: ①non-malignant encapsulated neoplasm involving the postero-medial region to the condyle; ②surgical exposure was incomplete by rotating or moving backward of the condyle based on the digital surgical simulation. RESULTS: All masses were resected successfully by using the novel approach with no damage to the critical nerves and vessels. The average follow-up period was 29.8 months (range 6-56 months). No recurrence, secondary deformity or facial paralysis were found. The average of mouth opening was improved from 27 mm to 34 mm after surgery. The condyles were fixed well with no resorption shown on CT scans. CONCLUSIONS: The transcondylar approach combined with posterior disc attachment release could be used for resection of non-malignant neoplasms involving the postero-medial region to the condyle. 3D reconstruction of CT and surgical simulation can help to determine the indications.
