ABSTRACT
BACKGROUND: In the context of tumor surgery, the median mandibulotomy as an access route to the oral cavity and oropharynx provides an excellent overview of the surgical site. However, it is not regarded entirely unproblematic with regard to early and later complications that may arise.
OBJECTIVE: The results and complications of the median mandibulotomy will be presented based on data co llected from our own patient collective.
MATERIALS AND METHODS: A total of 21 patients who had undergone a median mandibulotomy as part of tumor surgery at the Department of Otorhinolaryngology of the SRH Zentralklinikum Suhl were examined over a period from 01 January 2010 to 31 December 2020. The patient files were retrospectively evaluated.
RESULTS: A stair-step median mandibulotomy was performed in all 21 patients. Reconstruction was performed using a 2.8 mm thick angled mandibular plate and bicortical locking screws. The mean follow-up period was 29.8 months. In all, 7 patients (33%) had a recurrence at the time of surgery; 5 patients (24%) had already undergone pre-radiation. Furthermore, 18 patients (85.7%) received adjuvant radiotherapy. We found plate loosening or extrusion in 0 of 21 cases. A salivary fistula (4.7%) was observed in 1 patient. Trismus was found in 4 (19%) cases during follow-up. Osteoradionecrosis was found in 2 (9.5%) of 21 cases. Cosmetic defi cits were not observed.
CONCLUSION: Our results show that the stair-step median mandibulotomy in combination with a 2.8 mm thick reconstruction plate and bicortical locking screws leads to a stable and safe reconstruction even with pre-irradiated situations. Plate loosening or extrusion did not occur.
