Bilateral mandibular coronoid hypoplasia

Bilateral coronoid hypoplasia and complex odontoma: a rare concurrence of developmental pathology and odontogenic tumour of the mandible

“…It is usually considered as a developmental abnormality, and has been suggested to be due to activity of the temporalis muscle in prenatal and early postnatal life. However, it has also been suggested that coronoid hypoplasia may occur in individuals with unchanged muscle activity 1 3. The present case was diagnosed during routine radiographic investigation.…”

“…Coronoid hypoplasia is considered to be extremely rare and, so far, only two cases have been identified in the previously published literature 1. The first report was associated with Melnick-Needles syndrome and the second was an isolated case of coronoid hypoplasia 1 2. Thus it can be suggested that coronoid hypoplasia can occur in isolation or in conjunction with other pathological disorders.…”

Coronoid hypoplasia with developmental anomaly: A rare clinical-radiographic finding

“…6 In 2002, Nedim et.al found case of isolated bilateral mandibular coronoid hypoplasia in 33 year old female. 7 Other two cases were reported in 2015, Kudva et.al reported case of an isolated bilateral coronoid hypoplasia in 24 year old male 4 and case of bilateral coronoid hypoplasia associated with complex odontoma in 20 year old female patient is reported by Mohd et al 5 congenital deformities and developmental abnormalities of mandibular condyle can be classified as hypoplasia or aplasia, hyperplasia, and bifidity. Hypoplasia or aplasia of the mandibular condyle indicates underdevelopment or non development associated with various craniofacial abnormalities.…”

“…Three dimensional imaging in form of CT or Cone Beam Computed Tomography (CBCT) must be considered in the investigation of osseous morphology of TMJ.In the present case report, clinical and radiographic features were similar to the cases discussed in various litretures. [4][5][6][7]9 Various treatment approaches have been proposed. It is treated by multimode with the help of oral surgeon, general surgeon, plastic surgeon, and orthodontist.…”

Mandibular Coronoid Aplasia with Condylar Hypoplasia: A Very Rare Case with the Review of Literature

“…Four of the other cases are bilateral coronoid hypoplasia. 1,4,6,7 Only one case is unilateral coronoid hypoplasia. 8 Our case is the second unilateral coronoid aplasia case reported so far.…”
