Classification and Treatment of Complications Related to Titanium and Biodegradable Miniplates Using the Lip-Split Transmandibular Approach for Oral and Oropharyngeal Oncological Surgery.

Background: There is a lack of classified definitions and corresponding treatment principles for complications related to titanium miniplate (TMP) and biodegradable miniplate (BMP).

Aims: This study proposes a classification system for complications related to TMP and BMP osteosynthesis and evaluates the effectiveness of the classification system in the treatment of the complications.

Methods: One hundred forty-two patients with advanced-stage oral cavity and oropharynx squamous cell carcinoma (SCC) underwent oncological surgery via lip-split transmandibular (LTM) approach including midline, paramedian, stair-step, and triangle.
