Discuss in detail Cervicofacial Actinomycosis.<\/strong><\/p>\n<p><strong>Answer.<\/strong> Actinomycosis is a chronic granulomatous suppurative and fibrous type of disease caused by anaerobic, gram- positive, non-acid fast bacteria.<\/p>\n<p>Most common microorganisms are Actinomyces israelii, A. actinomycosis, A. viscosus and A. odontolyticus.<\/p>\n<p><strong>Cervicofacial Actinomycosis Predisposing Factors<\/strong><\/p>\n<ul>\n<li><strong>Trauma:<\/strong> Break in the continuity of mucosa due to trauma or by surgery.<\/li>\n<li><strong>Local factors:<\/strong> Infections leading to cervicofacial actinomycosis are endogenous in origin and occur when dental plaque, calculus or the gingival debris contaminates deep wounds around the mouth. Carious tooth can also cause cervicofacial actinomycosis.<\/li>\n<li><strong>Others:<\/strong> Hypersensitivity reaction and secondary bacterial invasion may act as predisposing factors.<\/li>\n<\/ul>\n<p><strong>Cervicofacial Actinomycosis Clinical Features<\/strong><\/p>\n<ul>\n<li>It is most common type of actinomycosis and is seen in adult males.<\/li>\n<li>Submandibular region is most frequent site of infection.<\/li>\n<li>Trismus is most common feature before formation of pus.<\/li>\n<li>The first sign of infection is characterized by formation of palpable mass. Mass is painless and indurated.<\/li>\n<li>There may be associated changes detectable at portal of entry such as non-healing tooth socket, exuberant granulation tissue or periosteal thickening of alveolus.<\/li>\n<li>Development of fistula is common. Skin surrounding fistula is purplish. Consistency of adjacent tissues is doughy.<\/li>\n<li>Sulphur granules: Hard circumscribed tumor-like swelling may develop and undergo breakdown, discharging yellow fluid containing submicroscopic sulfur granules.<\/li>\n<\/ul>\n<p><strong>Cervicofacial Actinomycosis Oral Manifestations<\/strong><\/p>\n<ul>\n<li>It produces swelling and induration of tissue.<\/li>\n<li>It may develop into one or more abscess, which tends to discharge upon the skin surface liberating pus, which contains typical sulphur granules.<\/li>\n<li>There may be non-healing tooth socket, exuberant granular tissue and periosteal thickening of alveolus.<\/li>\n<li>It is common for sinus, via which abscess is drained, to heal but due to chronicity, new abscess are formed and perforate through skin surface.<\/li>\n<li>Disfigurement of face is present as infections involve maxilla and mandible<\/li>\n<li>On tongue, lesion is painful nodule which eventually ulcerates.
