The hypothetical role of congenital hypotonia in the development of early coronoid hyperplasia

2012

Abstract Background Coronoid hyperplasia (CH) is an abnormal bony elongation of a histologically normal coronoid process. Its definitive cause remains unknown. Objectives To analyze the possible implication of congenital hypotonia in the pathogenesis of early coronoid overgrowth. Patients and methods Two infants with congenital hypotonia were evaluated for limited mouth aperture. Bilateral CH was diagnosed. Transoral coronoidectomy was followed by an early dynamic physiotherapy program. Results Significant improvement of maximum interincisal opening was achieved. The review of the scientific literature proved the diagnosis of CH in the infant age group is extremely unusual and the etiology …
