Surgical removal of a dislocated lower third molar from the condyle region: case report


Wassouf, A; Eyrich, G; Lebeda, R; Grätz, K W (2003). Surgical removal of a dislocated lower third molar from the condyle region: case report. Schweizer Monatsschrift für Zahnmedizin SMfZ, 113(4):416-420.

Abstract

INTRODUCTION: Migration of dislocated lower third molar into the condylar region is quite rare. Attention should be taken to avoid condyle fracture. METHODS: 49-year-old patient had an ectopic lower left third molal in the condylar region, suffered from a submandibular and masseter space abscess. Removal of the molar via intraoral approach was chosen avoiding facial nerve branches and unnecessary scar formation. Coronoid process is removed, the tooth is separated and removed. The defect is filled with iliac cancellous bone. The coronoid process was fixed as a cover with a resorbable plate and screws (BIONX). RESULTS: Removal via intraoral approach is possible. Hypesthesia existed postoperatively, became normal later. CONCLUSION: Annual observation is strongly recommended. Intraoral approach is superior to the extraoral approach. Removal of the coronoid process minimizes the masticator forces. Separation of the tooth is essential. Filling the defect with cancellous bone accelerates the healing.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
