ABSTRACT
Introduction: Patients affected with mucormycosis of maxilla have been increasing following Covid-19 infections. We followed the reconstruction of the maxilla using 3D manufactured patient-specific implants. The additive manufacturing technology is capable of fabricating custom-made titanium implants precisely for oral and maxillofacial reconstructions. Aim: To analyse the effectiveness of 3D manufactured patient-specific implants in the reconstruction of maxilla affected by mucormycosis secondary to Covid-19. Methodology: This study was conducted among 20 patients receiving patient-specific implants for surgical and prosthetic reconstruction of the maxilla. The parameters analysed at baseline, 3 months, 6 months, and 12 months were pain, implant exposure, infection, wound dehiscence, fit of implant, postoperative surgical rating scale, and patient experience evaluation rating scale. Results: Inferential Statistics revealed a positive correlation. Conclusion: From the present data, it can be concluded that within the limitations of the study, patient-specific implant systems are an effective treatment strategy for the reconstruction of the maxilla affected by mucormycosis secondary to Covid-19. More studies with larger sample size and longer follow-up periods are required to substantiate the results from the present study.

ABSTRACT
Ossifying fibroma is a rare benign osteogenic neoplasm arising from undifferentiated cells of the periodontal ligament. Ossifying fibroma have a well-defined border that differentiates it from fibrous dysplasia clinically, these tumors manifest as a round or ovoid, expansile, painless, slow-growing mass may displace the roots of adjacent teeth and also cause root resorption. They occur at second to fourth decade of life. Radiologically the lesion appears as a dense radiopaque mass surrounded by a thin, well-defined regular radiolucent rim. Patient underwent thorough history taking and complete face, ear, nose, and throat examination. Computed tomography maxilla, orthopantomogram, paranasal sinus reveals entire maxillary sinus involved in one case. Nasal septum deviated to the opposite side, airway reduced on the side of swelling seen in one case. Root resorption seen in two cases and missing teeth in seen in case 1. In our study in case 1, the tumor involved maxillary sinus, medial wall of the nose. The tumors were excised by Weber-Fergusson and in case 2 the tumor was excised by maxillary vestibular approach. Overall recurrence rates after resection is reported to range from 30 to 56%.
ABSTRACT
OBJECTIVE: The aim of the study is to evaluate the usage of Dieffenbach's modification of Weber-Fergusons approach in the treatment of lesions involving maxilla. STUDY: In this study five different maxillary pathologies were approached through Dieffenbach's modification of Weber-Fergusons approach. Partial and subtotal procedures were performed depending on the type of pathology and the extent of the lesion which was assessed both clinically and radiologically. The study evaluates the easy exposure of the site, post operative complications like scar formation and infra orbital nerve parasthesia. RESULTS: There were two subtotal maxillectomy procedures and three partial maxillectomy procedures approached through Dieffenbach's modification of Weber-Fergusson's approach. All the cases recovered well in the post operative healing period without noticeable scarring. There was parasthesia in three cases which subsided in 3 months. CONCLUSION: The approach through Dieffenbach's modification of Weber-Fergusons incision gave better visibility and accessibility to the lesions of maxilla. Because there is direct access to the pathology, the inadvertent resection of the un-involved structures is prevented thus minimizing the morbidity.
ABSTRACT
Condylomata acuminatum is a sexually transmitted infectious disease caused by human papiloma virus on the skin. The transmission is mainly by close contact with infected person and autoinoculation. In oral cavity the condition manifests as soft pink nodules which proliferate and coalesce rapidly to form diffuse papillomatous clusters of varying size. Odontogenic myxoma is a rare tumor of jaws which occurs in the tooth-bearing areas of the mandible and maxilla. It is an uncommon, benign, but locally aggressive neoplasm. This case report highlights a 17-year-old girl with two lesions in oral cavity with soft tissue growth on the palate which has been diagnosed as Condyloma Acuminatum, treated by surgical excision and a large swelling on the right side of the mandible in the same patient diagnosed as odontogenic myxoma where marginal resection was performed.
