Radiologic findings in sinonasal myiasis

Nasosinusal myiasis in elderly patient with mucocutaneous leishmaniosis

BACKGROUND

Myiasis is a condition in which flies are attracted to infected and/or necrotic tissues and deposit eggs that hatch into larvae. It may bring serious functional and aesthetic sequelae when involves nasal and parasinusal cavities; however, there is a lack of such reports in the literature.

METHODS

We present and briefly discuss herein the clinical and surgical management of nasosinusal myiasis in an elderly patient previously affected by mucocutaneous leishmaniosis.

RESULTS

Facial computed tomography was used to confirm the nasosinusal involvement. Next, osteotomies were performed, followed by the mechanical removal of larvae, bilateral sinusectomy and pharmacological therapy.

CONCLUSION

A complicated case of nasosinusal myiasis was surgically managed, resulting in a good prognosis for the patient.

Rhinosinusitis in children

Rhinosinusitis is the inflammation of the mucous membranes of nose and paranasal sinus(es). 5-13% of upper respiratory tract infections in children complicate into acute rhinosinusitis. Though not life threatening, it profoundly affects child's school performance and sleep pattern. If untreated, it could progress to chronic rhinosinusitis (CRS). The pathogens involved in perpetuation of CRS consist of multidrug-resistant mixed microflora. CRS is challenging to manage and could further extend to cause eye or intracranial complications. In children, CRS diagnosis is often either missed or incomprehensive. Due to this, morbidity and strain on healthcare budget are tremendous. Flexible fiberoptic endoscopy has revolutionized management of CRS. Its utility in children is being increasingly recognized. Optimal management entails specific appropriate antimicrobials as well as treatment of underlying causes. The aim is to normalize sinus anatomy and physiology and regain normal mucociliary function and clearance.

Myiasis

Myiasis is defined as the infestation of live vertebrates (humans and/or animals) with dipterous larvae. In mammals (including humans), dipterous larvae can feed on the host's living or dead tissue, liquid body substance, or ingested food and cause a broad range of infestations depending on the body location and the relationship of the larvae with the host. In this review, we deeply discuss myiasis as a worldwide infestation with different agents and with its broad scenario of clinical manifestations as well as diagnosis techniques and treatment.
