Oronasal fistula (ONF) is the most common complication after palatoplasty in patients with cleft lip and palate (CLP). When left untreated, it may negatively affect the quality of life, leading to development of other comorbidities. This study reports for the first time, the use of a portion of a hyperplasic tissue associated with pedicled buccal fat pad flap to repair a large anterior ONF in a 60-year-old man. The hyperplasic tissue may have developed due to the combination of a loose fitting upper denture and long-term use of dihydropyridine calcium channel blocker (amlodipine besylate). There is controversy in the literature about use of pedicled buccal fat pad flap in the anterior region. However, in this study, we report successful repair of a large anterior ONF using a portion of a fibroepithelial hyperplasic tissue associated with pedicled buccal fat pad flap.

This work presents the wrap technique developed by the authors aiming to avoid the occurrence of unaesthetic deep labiomental fold in genioplasty. The technique recommends the use of particulate bone graft that is wrapped on collagen or a Surgicel membrane which is placed over the osteotomized segment of the chin fixated with a prebent 4-hole titanium plate.

Background: To evaluate whether genetic polymorphisms in FGF3, FGF10, and FGF13 are associated with temporomandibular disorders (TMD) in patients that presented dentofacial deformities requiring orthognathic surgery., Material and Methods: The sample comprised a total of 113 patients of both sexes. The diagnosis of TMD was performed before orthognathic surgery between Research Diagnostic Criteria for Temporomandibular Disorders (RDC-TMD). According to the TMD assessment, the patients were divided into 3 major groups: myofascial pain, articular disc displacements and other TMD conditions (arthralgia, arthritis, and arthrosis). Genomic DNA was collected from saliva samples and genetic polymorphisms in FGF3 (rs1893047 and rs7932320), FGF10 (rs900379) and FGF13 (rs5931572 and rs5974804) were analyzed by real-time polymerase chain reactions. The association between the TMD conditions and the genetic polymorphisms assessed were analyzed by Poisson Regression. The model was calculated on bivariate and adjusted by sex. The established alpha was 5%. Data were analyzed by using SPSS software (IBM, Armonk, NY)., Results: The genetic polymorphisms rs7932320 in FGF3 (P < 0.001) and rs900379 in FGF10 (P < 0.05) were associated with the presence of muscle disorder. The genetic polymorphisms rs1893047 in FGF3, rs900379 in FGF10, and rs5974804 and rs5931572 in FGF13, were associated with the presence of disk displacement (P < 0.05). The genetic polymorphisms rs1893047 and rs7932320 in FGF3, rs900379 in FGF10, and rs900379 in FGF10 were associated with other TMD conditions (P < 0.05)., Conclusion: Genetic polymorphisms in FGF3, FGF10, and FGF13 genes were associated with temporomandibular disorders in a population with dentofacial deformities.
