ABSTRACT

OBJECTIVE: To analyze the results obtained with hydroxyapatite bone cement (HABC). PATIENTS: A total of 73 ossiculoplasties with HABC were evaluated. Ears were divided into 4 groups: Group 1: Reinforcement of the incudo-stapedial joint with HABC; Group 2: Reconstruction of an incus long process defect with HABC; Group 3: Partial ossicular reconstruction between stapes and malleus handle with HABC; Group 4: Reconstruction of stapes with mobile or fixed footplate with moderate or extensive incus long process erosion using a titanium piston glued to the incus remnant using HABC. RESULTS: The mean follow-up was 21 months. The percentage of postoperative average air-bone gap (ABG) < or = 20 dB for groups 1, 2, 3 and 4 were 100%, 95%, 83% and 91% respectively; for ABG < or = 10 dB: 90%, 71%, 50% and 50%. No complications related to HABC and extrusion occurred. CONCLUSION: Today, the use of HABC seems to help us improve our functional results and also to avoid extrusion. In our experience, ossiculoplastie with HABC seems to provide better and more stable functional results. HABC is safe and easy to use. The use of cement with or without biocompatible ossicular prostheses allows us to repair different types of ossicular defects whilst trying to conserve an anatomical and physiological ossicular chain. Reconstruction of the incus long process or incudo-stapedial joint defect with cement is preferable rather than using partial ossicular reconstruction with HABC.

ABSTRACT

Dacryocystorhinostomy (DCR) in children is indicated in cases of common congenital nasolacrimal duct obstruction (CNLDO) unresponsive to medical therapy, probing or intubation. The purpose of this manuscript is to evaluate the effectiveness of endonasal endoscopic pediatric DCR. The authors present a series of eight children (seven boys and one girl) who underwent a pediatric endonasal DCR between September 2007 and December 2008. The mean age was: 4.3 years (range: 8 months to 9 years old). Three children had a craniofacial abnormality. There were ten primary DCRs and one revision DCR. In nine cases, the indication was a pure primary low mechanical obstruction persistent after one or more probings. In the 10th case there was also a stenosis of the inferior canaliculus diagnosed during the DCR. The revision DCR was indicated because of the closure of the stoma created 3 years ago. A silicone intubation was put in place only in two cases: in case of a stenosis of the inferior canaliculus (3 months) and the other in case of revision DCR (1 month). The follow-up for primary DCRs was 10.5 months (range: 6-15) and for revision surgery 6 months (after the retrieve of the stent). In primary DCRs, there was a complete resolution of symptoms in nine out of 10 cases. The 10th case experienced a transient slight epiphora during a viral rhinitis. In case of revision DCR, the child was free of symptoms. In conclusion pediatric DCR is a very effective and safe procedure for the treatment of a low mechanical obstruction of the lacrimal pathway in children unresponsive to previous probings. Stenosis of the inferior canaliculus can give some slight intermittent epiphora despite a wide and patent stoma. Moreover craniofacial abnormalities are more common in children than in adults undergoing a DCR.
