A challenging case of a large intraorbital foreign body perforating the nasal septum in a child.

A 5 year old boy with a history of fall from a height of about 4 feet, presented after one week with swelling, watering and discharge of the right eye. He had severe conjunctival chemosis with superior displacement of the globe. Computed Tomography (CT) showed a linear low attenuation tract in the right orbit extending from the inferolateral wall up to the left uncinate process of the ethmoid bone with increasing Hounsfield unit after 10 days. The parents did not agree for early exploration. After 10 days an exploration was done and a large linear and irregular wooden foreign body (FB) measuring 4.5 x 1.5 cm2 was removed from the right orbit and a smaller one from the nasal cavity. Four weeks post surgery, his vision was 6/9 in the right eye with the eyeball in the normal position. This case was challenging because of the late presentation, parents not agreeing for early exploration, difficulty in diagnosing by CT and a large and very deep penetrating FB.

Transnasal tracheobronchial stenting for malignant airway narrowing under local anesthesia: Our experience of treating three cases using this technique.

PURPOSE: To study the technical feasibility of tracheobronchial stenting via transnasal route under bronchoscopy and fluoroscopic guidance in severe malignant airway strictures using self-expandable nitinol stents. MATERIALS AND METHODS: We describe three patients with malignant airway strictures, treated entirely via transnasal route under local anesthesia using bronchoscopic and fluoroscopic guidance. Nasal route allowed convenient access to the airway for the bronchoscope across the stricture and a guidewire was introduced through its working channel. The 18F tracheal stent and the 6F bronchial stent assembly could be easily introduced and deployed under bronchoscopic (reintroduced through the other nostril) and fluoroscopic guidance. RESULTS: We achieved technical success in all the three patients with immediate relief of dyspnea. CONCLUSION: Transnasal airway stenting with self-expandable nitinol stent using bronchoscopic and fluoroscopic guidance under local anesthesia is a safe and effective method with minimal patient discomfort.
