ABSTRACT
@#Introduction: The morphology of the condyles changes naturally with age, gender, face type, occlusal force, functional load, malocclusion type, and the right and left sides. Although condylar shape and size differ throughout populations, there have been few investigations on condylar morphology, particularly in the Malaysian population. Methods: This retrospective, observational, cross-sectional survey was conducted at the Oral and Maxillofacial Surgery Clinic of Sarawak General Hospital from September 2021 to March 2022, involving radiographic assessment of condylar morphology from 893 panoramic radiographs. Age, gender, ethnicity and dentition status using Eichner index were extracted from the data. Descriptive statistics were used. Pearson’s chi-square test was used to determine the association between the independent variables (age, gender, ethnicity and dentition status) and the shape of the mandibular condyle. A p-value of < 0.05 was considered statistically significant. Results: Only 450 panoramic radiographs were included in this study. The condyles were outlined and grouped into four categories, namely pointed (40.2%), round (32.8), angled (18.8), and flat (8.2%). Condylar morphology was found to be significantly associated with gender (p<0.005) and insignificant with other independent variables. Conclusion: The findings suggest that the most prevalent condylar morphology among the Sarawak population is the pointed shape, in contrast with other previous studies that reported the round shape condylar morphology as the majority shape.
ABSTRACT
@#Replantation of fingers is highly complex and technically challenging. Surgeons are serious with their selection criteria as many factors are involved in determining good surgical outcome. Improper storages of amputated parts are usually denied the option for replantation. We report a 42-year-old lady who was assaulted with a machete and presented with total amputation of left thumb. The amputated thumb was stored in a plastic bag directly on ice cubes which eventually melted; thumb immersed in water for two hours. On examination, the amputated thumb was neither macerated nor frozen. Replantation was attempted and was successful. There are limited reports on proper methods of storage of amputated fingers pertaining to daily practical scenario. Yet, it is a strict criterion for surgeons in attempting replantation. Direct contact of amputated fingers on ice and immersion in hypotonic solutions leads to irreversible tissue damage. In our case, two hours of unfavourable storage did not affect surgical outcome. In conclusion, clinical assessment of the amputated part is essential in deciding for replantation. Combination of direct contact with ice and immersion in hypotonic solution for two hours should not be a contraindication for replantation.
