Postextraction Mucormycosis in Immunocompromised-Patient Management and Review of Literature.

Mucormycosis is an uncommon aggressive, opportunistic infection that can produce widespread orofacial tissue necrosis. This primarily affects immunocompromised individuals. It is the deadliest and most rapidly progressing type of human-affecting fungal infection. The aim of the study is to investigate the diagnostic criteria and treatment approach in 10 cases of mucormycosis in the author's institute from 2008 to 2019. Moreover, a review of the English literature presents all cases of mucormycosis after tooth extraction. Ten patients at our institute have been treated. They were evaluated and discussed as per their diagnostic criteria, surgical treatment, and mortality rates. All 10 immunocompromised patients had a primary hematologic malignancy. The criteria for a positive diagnosis were clinical symptoms and a biopsy for microbiological culture and histologic analysis. Each patient was subjected to vigorous surgical resection and underwent antifungal treatment. Seven patients died because of their main disease. Owing to the unregulated spread of mucormycosis, 2 patients died. Four cases were diagnosed after maxillary tooth extraction. The most important factor for patient survival tends to be the management of the underlying disease with early detection and active surgical and antifungal action. Four of 10 cases diagnosed with mucormycosis appeared after tooth extraction, a relatively high number compared with the literature. Therefore, it is the dental profession's obligation to be familiar with the possibility of the potentially severe and possibly fatal complication.
