Extra oral sinus tract: A case report

Abstract

When there are no intraoral symptoms, extraoral draining sinus of odontogenic origin can be diagnosed as a cutaneous lesion. It is unusual and can be mistaken for many different conditions, such as furuncle, parotid fistula, preauricular sinuses, pericoronitis pertaining to the mandibular third molars, periapical and periodontal pathology, and many more. Because doctors are often unaware of the odontogenic aetiology of these situations, patients may seek therapy from them; nevertheless, misdiagnoses frequently result in incorrect treatment. Objective: To analyze the comprehensive management of a case involving an extraoral draining sinus that was effectively treated. Case Report: Pulpal necrosis resulting in an extensive periapical lesion is the aetiology of the extraoral draining sinus in this instance. If treatment is not received, intra-radicular bacteria, mostly obligate anaerobes, in infected root canals may lead to these kinds of symptoms. Conclusion: Since these instances are rare and do not exhibit any dental symptoms, it is critical to recognize them in order to treat the illness and prevent needless measures like protracted antibiotic prescriptions. Therefore, in order to provide an accurate diagnosis for any cutaneous sinus tract, the dental aetiology should be checked out, determined, and the patient can receive the appropriate care.
