ABSTRACT
Background & Objective: The present study was conducted with the aim to clinically and radiographically evaluate the efficacy and efficiency of the direct sinus lift with simultaneous implant placement and bone grafting, and to evaluate bone height with the merits and demerits of lateral approach for sinus membrane elevation. Methodology: This randomized prospective study consisted of 10 patients who met the inclusion and exclusion criteria. The patients were selected irrespective of the age, sex & socioeconomic status, with the residual alveolar bone height between 1 to 4 mm in the edentulous posterior maxillary region. Direct sinus lift was carried out with simultaneous implant placement. Bovine graft (xenograft) was used as a sole grafting material. Patients were followed up for 36 months of prosthetic rehabilitation. Results: Pre-operative alveolar bone height was on an average 2.9 mm (ranging from 1 to 4 mm) with the standard deviation of 0.67 mm. After 36 months of loading, there wasn’t any clinical or radiographical complication. On an average 13 mm bone height was evident (ranging from 11.5 to 14 mm) with the standard deviation of 0.81 mm. Conclusion: Direct sinus lift is an excellent technique for the rehabilitation in the cases with severely atrophic posterior maxilla.
ABSTRACT
Dermoid cysts of the Pre-auricular area are extremely rare. We report one case of Pre-auricular dermoid Cyst. Case involved a gradually enlarging mass of the superior and anterior aspect of the pre-auricular region on left side. During the operation, a lesion was found just under the skin, not fixed parotid or adjacent cartilage. Histologically, specimen contained desquamated squamous epithelium and keratin in the lumen. Dermoid cysts at the pre auricular region are rare and a diagnostic challenge, but , it should be considered as a differential diagnosis in cases of painless long standing enlargement of parotid gland which is soft in consistency.
ABSTRACT
Summary: Odontogenic keratocysts (OKC) now officially known as Keratocystic odontogenic tumor (KCOT) is a benign odontogenic intraosseous tumor which is potentially agrressive having distinguished clinical and histopathological features. Based on a literature review, more aggressive treatment — either resection or enucleation supplemented with Carnoy’s solution with or without peripheral ostectomy — results in a lower recurrence rate than enucleation alone or marsupialization. WHO’s reclassification of this lesion from cyst to tumour underscores its aggressive nature and should motivate clinicians to manage the disease in a correspondingly aggressive manner. The purpose of this paper is to review and discuss the redesignation of KCOT and the implications for treatment.
