Customized Nasal Prosthesis for a Jones Lacrimal Bypass Tube Using 3-Dimensional Planning and Printing Technology

Abstract

A 35-year-old woman was treated for extensive squamous cell carcinoma of the nasal septal mucosa with total rhinectomy, including removal of the nasal septum, and chemoradiotherapy. A magnet-retained nasal prosthesis was fitted. She had developed right-sided epiphora from total proximal lacrimal canalicular obstruction, for which an angled Jones lacrimal bypass tube was inserted. The tube, however, intermittently rotated in the nasal cavity, causing recurrent epiphora and irritation at the caruncular site. With the aid of 3-dimensional technology, we designed a septum for the prosthesis that stabilized the tube within the nasal cavity. At the follow-up 2 years later, the patient was satisfied with the nasal prosthesis and lacrimal stent. To our knowledge, this report is the first to describe a patient-specific nasal prosthesis adapted for a Jones tube after total rhinectomy.
