Cutaneous draining sinus tract: An odontogenic etiology

Untitled

“…If it cannot, it is best to remove it and complete resection of the fistula as well. There should be administration of systemic antibiotics if the patient is diabetic, immunosuppressed or has signs of systemic infection [26][27][28][29]. Once the infection is treated the sinus tract will heal in 5-14 days and closes by secondary intention, but the esthetic results are not so favorable; patients present scaring and depressions of the skin, which is why it is always recommended surgical removal of the fistula [9].…”

Cutaneous Sinus Tracts of Odontogenic Origin: Two Case Reports

“…2,6 Of the reported cases, 80% arise from mandibular teeth. Mandibular incisors and cuspids typically drain to the chin or submental region.…”

“…Dental fistulas may arise from infection of the maxillary teeth, resulting in sinus tracts erupting intranasally or the nasal sinus or inner canthal areas. 2,5 Tracts in the mandibular, submandibular, and neck regions are most often associated with disease of the mandibular molars. Osteomyelitis is a rare complication.…”

Cutaneous facial sinus tract of denture-related aetiology? A case report

“…There are many reports of sinuses relating to dental sepsis and peri-apical infection. [1][2][3][4][5][6][7][8][9] Many of these are reported in the plastic surgery and dermatology literature and raise the need for vigilance across all specialities. Diagnostic difficulty is a feature of many of these cases and it is recognised that confusion can occur between facial sinuses of dental origin and pyogenic granulomas, foreign body reaction, deep seated mycoses, osteomyelitis or even squamous cell carcinomas.…”

“…2 There are reports of patients undergoing multiple excisions and biopsies, lengthy antibiotic courses, radiation therapy or electrodessication before the dental cause is identified. 3 In all reported cases removal of the causative tooth or root canal therapy is the recommended treatment. A series of 37 cases found that 85% of causative teeth were in the mandible with 81% draining to the chin or submental region.…”
