ABSTRACT: Mandibulectomy is a surgery that leads to heavy aesthetic and functional
sequelae. Surgical complications have been noted but have not yet been
evaluated. The aim of this study was to evaluate the surgical complications of
mandibulectomy. This is a retrospective descriptive and analytical study of
patients who underwent mandibulectomy in the Department of Maxillofacial
Surgery of the CHU JDR Befelatanana between January 2017 and December 2020. A
correlation between the occurrence of complications, parameters related to the patients and those related to the
surgery was sought. Patient-related parameters were: age and sex,
comorbidities, toxic habits and body mass index. The parameters related to the
surgery which were studied were the duration of the intervention, the size and
the seat of the bone defect, the interruption or not of the mandibular
continuity. Forty-six
cases were selected. The average age was 36.98 years and the sex ratio was 0.7.
Fifty percent of patients developed surgical complications. The total number of
complications was 38. Salivary fistula was the most frequent complication
(26.32%). No correlation was found between the occurrence of complications and
patient-related parameters. There were 69.57% of complications when the
procedure lasted more than 180 minutes (p = 0.003). A correlation was found
between the occurrence of complications and the size of the resected bone (p =
0.009). Among the complications, 56.52% occurred when the size exceeded 130 mm
(p = 0.03). The complication rate is high. The size of the resected bone and
the duration of the operation influence the occurrence of complications.
