RESUMO
AIM: This study aimed to explore the survival rate and quality of life (QoL) in patients who underwent segmental mandibulectomy and determine the associated factor with survival rate and QoL. MATERIAL AND METHODS: In this cross-sectional study, all patients who underwent segmental mandibular resection in the referral center of Shiraz University of Medical Sciences, Iran, during 2015-2019 were included. Inclusion criteria were segmental mandibulectomy due to any pathology and age of more than 8 years old. Demographic, clinical data and patient survival were recorded. EORTC QLQ-HN43 was used to evaluate QoL. RESULTS: Totally, 82 patients were studied. The overall 3-year survival rate was 69.5% (57 patients) (mean ± SD: 1.35 ± 1.03 years). According to univariate analysis, age (p-value = 0.001), hospital lengths of stay (p-value < 0.001), gender (p-value = 0.014, OR = 4.143), education (p-value = 0.015, OR = 0.291), pathology (p-value < 0.001, OR = 17.000), metastasis (p-value = 0.018, OR = 4.894), neck dissection (p-value < 0.001, OR = 52.381), frozen margin (p-value < 0.001 OR = 8.000), recurrence (p-value = 0.001, OR = 6.273), and status of chemoradiotherapy (p-value < 0.001) were significantly associated with survival rate. Logistic regression revealed that survival was associated with gender (p-value = 0.040, OR = 23.689), level of education (p-value = 0.019, OR = 0.019), and neck dissection (p-value = 0.019, OR = 175.781). According to univariate analysis, pathology (p-value = 0.003), neck dissection (p-value = 0.024), frozen margin (p-value = 0.004), and chemoradiotherapy (p-value = 0.026) were significantly associated with QoL. Linear regression revealed that QoL was associated with none of the measured factors. CONCLUSION: In conclusion, gender, level of education, and neck dissection were related to 3-year patients' survival. None of the measured factors in this study were associated with QoL.

INTRODUCTION: Odontogenic infections are polymicrobial in origin and can be life-threatening. Antibacterial failure is an important issue in the treatment of odontogenic infections. This study aimed to determine the factors associated with antibacterial failure in patients with head and neck infections with odontogenic sources. MATERIAL AND METHOD: This retrospective epidemiological study was performed using data collected from 229 patients with head and neck infections with an odontogenic source who had been operated on in Shahid Rajaee hospital from March 2014 to December 2019. RESULTS: 123 (53.7%) patients were female and there were106 (46.3%) males. The mean age ± SD was 33.01±13.37 years (range 7 to 80). The most common offending teeth were lower molars (81.7%) and lower premolars (5.7%). The most common site of infection was the submandibular area (36.4%) followed by the buccal (20.4%) and pterygomandibular (17.1%) regions. The most common pathogen was Streptococcus haemolyticus. The length of hospitalization was higher (4.66 days) in patients with failure of treatment compared to those without it (6.00 days) (p=0.002). A combination of penicillin G and metronidazole was prescribed for all patients with failure of treatment compared with 57.6% in patients without failure of treatment (p=0.002). There was no statistically significant difference between the two groups regarding age, duration of illness before hospitalization, WBC, gender and history of chemotherapy, hypertension, smoking, pregnancy, alcohol usage, diabetes mellitus, the rate of fever, trismus, dysphagia, malaise, antibiotic before hospitalization, and surgical approach. CONCLUSION: Possible determinants in this study were not associated with antibacterial failure. Further studies should be conducted to investigate this relationship.

RESUMO
The aim of this study was to measure the maximum voluntary bite force and recovery time in patients treated for different types of the maxillofacial fracture. Patients aged between 18 and 60 years, who received surgical treatment for a single isolated fracture of the maxillofacial structure, were included in this study. Healthy individuals without any maxillofacial abnormality were selected as the control group. Bite force (in kg) was measured at the first incisor tooth, bilaterally, prior to surgery and 2 weeks, 6 weeks, 3 months, and 6 months after surgery. Of 120 patients, 89 (74.17%) were male and 31 (25.83%) were female. Mean patient age (±SD) was 31.21 (±11.64) years. Bite forces relating to fractures of the zygomaticomaxillary complex (ZMC) with involvement of the arch and zygomaticofrontal suture reached normal levels after 6 weeks (from 3.89 (±1.11) to 10.82 (±1.29); p = 0.296 and from 4.20 (±0.93) to 10.70 (±1.70); p = 0.192, respectively). Bite force returned to normal after 3 months in fractures of the symphysis (from 2.05 (±0.97) to 12.18 (±0.77); p = 0.222), body (from 2.21 (±1.26) to 11.9 (±0.73); p = 0.750), angle (from 2.45 (±1.24) to 11.89 (±0.76); p = 0.769), condyle (from 2.45 (±1.27) to 11.25 (±0.82); p = 0.968), and ZMC with and without infraorbital rim involvement (from 3.83 (±0.93) to 11.92 (±0.84); p = 0.724 and from 3.7 (±1.21) to 12.03 (±0.82); p = 0.482, respectively). Patients with ZMC fracture involving the arch and zygomaticofrontal suture require fewer follow-ups in comparison with those with other maxillofacial fractures. Measurement of maximal bite force can help to evaluate dentofacial deformities before and after surgical treatment.
