No full textBackground: Severe microretrognathia with the absence of ascending mandibular ramus is a challenging deformity and treatment must aim to avoid tracheostomy or remove it as soon as possible. Although it is not often reported, mandibular distraction osteogenesis represents a valid treatment option in infants affected by hypoplastic mandible Pruzansky-Kaban type IIb and III. Case presentation: The authors describe 3 cases of infants affected by severe respiratory insufficiency due to congenital mandibular hypoplasia, with follow up ranging from 4 to 8 years. Clinical and technical considerations on treatment choices and outcomes are discussed starting from review of the literature and direct clinical experience. Conclusion: Early mandibular distraction, specifically bidirectional distraction, is an effective and repeatable technique that leads to mandible lengthening with counterclockwise rotation, pogonion projection increase, anteropositioning of the tongue base, and expansion of oropharyngeal volume with positive effect on the respiratory problems of the infant. Even in Treacher Collins patients, known to have a low decannulation rate, all of these elements are essential for effective speech and swallowing therapy and for a subsequent attempt of decannulation

No full textA rare case of multiple congenital epulis
No full textWe report a case in a female newborn infant of multiple congenital epulis, i.e. granular cell tumor, that was undetected during regular pregnancy ultrasound monitoring. At birth the neoplasms appeared as two voluminous lesions protruding from the newborn's mouth. The greater of them (5.5 cm × 4 cm × 3 cm) was pedunculated and attached to the external superior gingiva, shifting the alae nasi and making it difficult to enter the coanae. The second mass was somewhat smaller (3 cm × 4 cm × 2.5 cm), pedunculated and attached to the external inferior gum. A third smaller mass was less evident, unpedunculated and attached to the rim of the lower gingiva. Histologically the lesions were characterized by large cells, which had abundant pale acidophilic granular cytoplasm. A round-oval nucleus was located centrally. The cell membranes were distinct. Neither mitosis nor necrosis was found. Staining for cytoplasmic granules was intensely periodic acid-Schiff (PAS) positive and diastase resistant, lmmunohistochemical negativity for SlOO protein, positivity for lysozyme and numerous phagolysosomes in the cytoplasm of neoplastic elements, observed on ultrastructural examination, supported the hypothesis that the congenital type of granular cell tumor cannot have a Schwannian origin like that of the adult type, but is probably a mesenchymal lesion which, for unknown cause, regresses by a degenerative process
