Lyophilised Amniotic Membrane in Intraoral Surgical Defects: A Prospective Clinical Study.

Introduction: The incidence of infection and scarring in intraoral raw wounds are decreased when wounds are grafted with biological materials. The favourable results of many studies about amniotic membrane in wound healing inspired us to investigate the effects of lyophilised amniotic membrane in intaoral surgical defects. The aim of this study was to evaluate the healing of oral mucosal defects after application of lyophilised amniotic membrane (AM). Methods: Fifteen patients with oral precancerous lesions were included in this study. Lyophilised amniotic membrane was applied to the intraoral surgical defect, after wide excision of the lesion. The effectiveness of the lyophilised AM was evaluated by scoring the following parameters operability, haemostatic status, pain, feeding situation, epithelialisation, change in mouth opening, mucosal suppleness and safety. Results: The lyophilised amniotic membrane has been found to be effective in this study after evaluation of the parameters. No infection or allergic reaction was noticed after application of the lyophilised amniotic membrane in intraoral surgical defects. Discussion: In our study, the size and site of the surgical defect influenced the scar contracture so we suggest lyophilised AM may not prevent scarring for extensive surgical defects. All other findings regarding the effectiveness of lyophilised amniotic membrane in oral wound healing are in accordance with the findings of other studies conducted on hyperdry and cryopreserved AM. Conclusion: Within the limitations of the study, the results showed that the lyophilised amniotic membrane is a cost effective material for immediate coverage of the intraoral surgical defects.

Reconstruction and rehabilitation of short-range gunshot injury to lower part of face: A systematic approach of three cases.

Gunshot injuries are always known to cause severe morbidity and mortality when head and neck are involved. They vary in morbidity, which can occur in civilian surroundings. The wound largely depends on the type of weapon, mass and velocity of the bullet, and the distance from where it has been shot. Close-range gunshot wounds in the head and neck region can result in devastating aesthetic and functional impairment. The complexity in facial skeletal anatomy cause multiple medical and surgical challenges to an operating surgeon, demanding elaborate soft and hard tissue reconstruction. Here we presented the successful management of three patients shot by short-range pistol with basic life support measures, wound management, reconstruction and rehabilitation.

Aneurysmal bone cyst of maxillary alveolus: A rare case report.

Aneurysmal bone cyst (ABC) is a nonneoplastic rare pathologic entity of the jaws. Its locally aggressive nature and high recurrence rate after curettage make surgical resection a better treatment option. Here, we present a case of ABC of maxillary alveolus and its management by alveolectomy followed by white head varnish pack application in the surgical defect.
