Traumatic Canalicular Laceration Repair with a New Monocanalicular Silicone Tube.

PURPOSE This study evaluated the efficacy of a new pushed monocanalicular silicone tube in reconstructing traumatic canalicular laceration. METHODS This interventional case series enrolled 48 patients with a traumatic canalicular laceration. Patients with bicanalicular involvement were excluded. Canalicular repair was performed under an operating microscope and involved proximal end exploration of the canaliculus, stenting of the canaliculus with a 35-mm Masterka tube, and approximation of the lacerated canaliculi margins. After 6 months, anatomical and functional success rates were evaluated by diagnostic probing and by asking the patients (or their guardians) about tearing. RESULTS The mean age of patients was 32.2 ± 21.2 years (1.5-75 years). Of the 48 patients included, 38 were males. Lower canaliculus was involved in 35 patients. Other ocular injuries were observed in 38 patients. The average interval between the surgery and Masterka removal was 12.2 ± 1.4 weeks (10-16 weeks). Early tube extrusion was observed in 3 patients. No significant complication was observed in this series. Anatomical and functional success rates were 87% and 100%, respectively. CONCLUSION The results demonstrated that intubation of lacerated canaliculi with Masterka tube for canalicular repair was safe, effective, and simple with minimal complications.

Orbital volume augmentation with calcium hydroxyapatite filler in anophthalmic enophthalmos

Purpose: To report the long-term results of orbital volume augmentation using calcium hydroxyapatite filler injections in patients with anophthalmic sockets. Methods: Twelve eligible patients with post-enucleation socket syndrome (PESS) and small orbital volumes were included in our study. In this investigation, 1.5 mL injectable calcium hydroxyapatite (Radiesse) was utilized in an off-label application under local anesthesia. We evaluated the effect of orbital volume augmentation for correction of enophthalmos. Results: Five women and seven men with a mean age of 35 years (range, 21-72 years) were included in the study. The mean follow-up was 19.5 months (range, 16-27 months). Enophthalmos and deep superior sulcus were reduced in all patients during all follow-up visits postoperatively. The mean improvement of enophthalmos was 2.58 mm (range, 1-5 mm) and the improvement in deformity grading of superior sulcus was 0.83 (range, 0-4 grade). The mean marginal reflex distance increased by 0.6 mm (range of -1 to 3 mm). Complications included increase in ptosis in two cases and extrusion of the filler accompanied by discoloration of the skin in one case. Conclusion: The use of injectable calcium hydroxyapatite for orbital volume restoration in anophthalmic sockets is a simple, fast, and minimally invasive method with considerable long-term effects and low complications.
