ObjectiveThe aim of this retrospective analysis was to determine the age, gender, frequency
and distribution of trauma-associated hard tissue and soft tissue lesions of the
oral and maxillofacial region in a population from southern Taiwan.Patients and MethodsApproximately 10% of the 27,995 biopsy records of patients with history of trauma
resulting in lesions who were treated at our institution between 1991 and 2006
were examined for this study.ResultsIn the included records, there were 2,762 soft tissue and 26 hard tissue lesions.
Mucocele was the most frequent trauma-associated soft tissue lesion (955 cases).
The youngest patients were those who presented with mucocele (mean age = 27.3
years), while the oldest patients were those with peripheral giant cell granuloma
(58 years). The lower lip was the most frequent site of occurrence of mucocele
(676, 64.5%) and was also the predominant site of occurrence of all soft tissue
lesions (815, 29.5%), followed by the buccal mucosa (654, 23.4%) and the tongue
(392, 14.2%). Trauma-associated hard tissue lesions included only
osteoradionecrosis (24 cases) and traumatic bone cysts (2 cases).ConclusionAs little data of this nature have been reported from populations of Asian
developing countries, the findings of this retrospective analysis is valuable for
epidemiological documentation of type of traumatic oral lesions as well as for
informing the professionals and the layman about the importance of this category
of oral lesions.
Our results indicate that impaired p63 immunoexpression (predominantly Delta N isoform) is associated with the severity of oral epithelial dysplasias and up-regulation of p63 may play a role in the early stage of human oral tumorigenesis.
IntroductionA study of the whole spectrum of biopsied head and neck (HN) diseases in Taiwan has not yet been performed. Therefore, the current study aimed to provide updated information about HN lesions in a cohort of referral Taiwanese patients for histopathological examination.MethodsHN lesions (2000–2011) in patients with records of age, sex, and histological diagnoses were retrieved from the Oral Pathology Department of the institution. These lesions were classified into four main categories: tumor/tumor-like reactive lesions, cystic/pseudocystic lesions, inflammatory/infective lesions, and others/miscellaneous lesions.ResultsA total of 37,210 HN lesions were included in the current study. Most of these lesions were distributed in the group of tumor/tumor-like reactive lesions, followed by the groups of inflammatory/infective lesions, cystic/pseudocystic lesions, and others/miscellaneous lesions. Squamous cell carcinoma was the most common HN lesion, and was also the most frequent malignant lesion among the referral patients.ConclusionIt was worthy of note that squamous cell carcinoma and oral potentially malignant disorders comprised high percentages of all HN lesions for the present cohort of referral patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
