Accidental displacement of an impacted third molar, either a root fragment, crown, or the entire tooth, is a rare complication that occurs during exodontia. The most common sites of dislodgment of an impacted mandibular third molar fragment are the sublingual, submandibular, and pterygomandibular spaces. Removal of a displaced root tip from these spaces may be complex due to poor visualization and limited access. A thorough evaluation of all significant risk factors must be performed in advance to prevent complications. This paper reports the case of a patient who presented with a mandibular third molar root that was displaced into submandibular space. The case was managed intraorally under local anaesthesia and review of the literature.

Aim To highlight the spontaneous regeneration of mandibular segmental defects in young and pediatric cases and to review the literature of this unusual and rare phenomenon. Methodology Two case reports of a 17-year old male and a 8-month-old infant has been presented who underwent resection of mandible for benign tumors. These two cases have been compared with the existing literature of 61 cases published till date. Inference Spontaneous regeneration of mandible as a viable reconstructive option is not practically feasible. The consistency and predictability of the phenomenon is questionable. Bone grafting should probably be done immediately in all cases, even in young patients if a delay would interfere with quality of life. In infants and small children though, we propose that immediate reconstruction may be avoided to allow some regeneration at the defect site. If it does not occur, secondary reconstruction may then be considered.

A 15-year-old female reported to us with the chief complaint of swelling over left angle of the mandible and submandibular region from past seven-eight months [Table/ Fig-1]. Medical and family history of the patient was unrelevant. A swelling of size 3 x 2 x 2 cm extending slightly above the angle of mandible to submandibular gland region beneath the masseter muscle was noted. It was painless, non tender without any history of trauma to the region.There was no carious tooth in the oral cavity and mouth opening of the patient was normal. Third molars were not present and no bony expansion of buccal as well as lingual plate was observed that confirmed it as a non odontogenic in nature. On palpation it was soft spongy, diffuse in nature without pulsations and definite margins. The size of swelling was reduced on pressure over it depicted as a vascular pathology. Swelling was non tender without rise in local temperature and no change in the texture and colour of the skin. Provisional diagnosis such as arteriovenous malformation, Less than 20% of these are found in head and neck region. The masseter muscle accounts for 5% of all intramuscular haemangioma of head and neck region. They are non metastasizing tumours which may suddenly start growing in later stages. The present article will discuss the clinical presentation, diagnostic modalities and surgical treatment of cavernous Haemangioma involving masseter muscle in a 15-year-old young female patient in whom a surgical excision of whole lesion was done under general anaesthesia and no reoccurrence of the lesion was observed after one year of follow up. haemangioma, lipoma, lymphengioma, lymphoma and salivary gland pathology was made. Fine needle aspiration cytology was advised that yields a fresh blood on aspiration confirmed a vascular lesion of high flow in nature. Angiography was done to see the feeding vessel, the size and extent of the lesion. It revealed a 3 x 2 x 2 cm lesion beneath the layers of masseter muscle around the angle of mandible with feeding vessel at submandible gland region [Table/ Fig-2,3]. The lesion was easily accessible and surgical interventions were planned after discussion with patient and her guardians as they were not willing for long term sclerotheraphy.Under general anaesthesia using orotracheal intubation submandibular incision approximately 2.5 cm in length was given in the skin crease to minimise the scar visibility. Layer wise dissection of platysma was carried out to identified and retraction of marginal mandibular branch of facial nerve. Facial vessels were exposed and ligated to have large access [

CASE REPORTwas extending along the left pharyngeal wall in the tonsillar fossa of approximately of 3.5 × 2 × 3 cm in diameter. Laterally, it caused lateral displacement of left parapharyngeal space fat (Fig. 2). There was paratracheal lymphadenopathy with tracheal and esophageal invasion by the mass without involvement of major neck vessels. Full-body scan was done to rule out the primary or metastatic site. No evidence of tumor was found in other parts of body on radiological examination.The biopsy of the right upper paratracheal mass was taken by a pulmonary medicine specialist via the endoscopic approach. Histopathological examination revealed a diagnosis of moderately differentiated squamous cell carcinoma, which on immunohistochemistry was CK5/6 positive. The patient received radiotherapy 30G/15 fraction for 2½ weeks and chemotherapy with paclitaxel 280 mg, cisplatin 80 mg, dexamethasone 16 mg, gransetron, and mannitol 20% intravenous for six cycles. After 6 months of this regime, the patient was totally free from pain in his jaw. The patient has been followed for 1 year with no recurrence till date.
