RESUMEN
INTRODUCTION: Literature reviews are replete with discussions focusing on the incidence, types, and patterns of disruption in TM joint function, besides enumerating and classifying its causes. However, atypical situations do present, such situations warranting a detailed, methodical assessment before therapeutic institution. PRESENTATION OF CASE: Described here is management of a unique case of post-traumatic pseudo-ankylosis in a 8year old child that had an old fractured condyle, displaced and dislocated anteriorly into the sigmoid notch, with eventual fusion to the ipsilateral zygomatic arch on its medial side. DISCUSSION: Although conventional imaging tools still have relevance, but the significance of multi detector CT scan with multiplanar reformation and three dimensional images have a become unequivocally a standard part of assessment of such complex facial injuries regardless of therapeutic setting. The probable explanation for the condylar fracture and unusual anterior dislocation of the condylar segment is also hypothesized. CONCLUSION: Although Post traumatic ankylosis is common in developing countries like India, distinct cases do present rarely which requires a disciplined approach in the management of such cases.
RESUMEN
Jacob's disease is a rare condition consisting of pseudojoint formation between enlarged coronoid process and the inner surface of the zygoma. The authors report a 45-year-old female patient who presented with limited mouth opening (5 mm) and swelling of the left zygoma. No temporomandibular joint disease was diagnosed. 3D computed tomography images showed a mushroom-shaped coronoid growth with pseudojoint formation medial and superior to the zygomatic arch. Under general anaesthesia, coronoidectomy was carried out through a combined extraoral and intraoral approach. Histopathological examination revealed normal trabecular bone covered with hyaline cartilage. To the best of the authors' knowledge this case is the fifth typical mushroom-shaped Jacob's disease; only four similar cases have been reported. A review of the literature revealed only 39 histologically proved cases of Jacob's disease cases up to 2010. Aggressive physical treatment was given to improve function and maximum mouth opening, which had increased to 40 mm at 3 months follow-up. The literature concerning this condition's aetiology, pathogenesis, clinical characteristics, diagnosis, and treatment is reviewed.

Malignant melanoma is a neoplasm of epidermal melanocytes. It is one of the most biologically unpredictable and deadly of all human neoplasms. However, malignant melanoma in the oral cavity is a rare malignancy, accounting for 0.2% to 8% of all melanomas. It has a grave prognosis, with a 5 year survival of 10-20%. We present a case of malignant melanoma of lingual gingiva of left mandibular molars with ipsilateral submandibular lymph node metastasis. We performed peripheral osteotomy of primary lesion followed by modified radical neck dissection by sparing internal jugular vein and patient had received postoperative radiotherapy.
