    Journal: Ann Otol Rhinol Laryngol; 2012 Nov; 121(11):701-7. PubMed ID: 23193901.
    Abstract:
    OBJECTIVES: We sought to document the incidence of and risk factors for adverse events after medialization laryngoplasty with Montgomery implant insertion in patients with unilateral laryngeal nerve paralysis. METHODS: We studied a retrospective series of 191 patients consecutively managed at a university teaching hospital. RESULTS: No adverse events were noted in 79.8% of the patients. Intraoperative, immediate, and late postoperative adverse events were noted in 8.3%, 8.9%, and 4.1% of the patients, respectively. The various adverse events noted were failure to insert the implant (3.6%), difficulties in stabilizing the implant (4.8%), misplacement of the implant (2.1%), dyspnea (2.7%), hematoma (4.8%), extrusion (1.6%), persistent morphological laryngeal alterations (1.6%), and keloid scars (1.1%). Tracheotomy, procedure-related death, and infection at the insertion site were not encountered. No significant statistical relationship was noted between the various adverse events encountered and the variables under analysis. CONCLUSIONS: Our data demonstrate that medialization laryngoplasty with Montgomery implant insertion in patients with unilateral laryngeal nerve paralysis from various causes is a relatively safe, reliable, and reproducible procedure with a short learning curve.
