AbstractAlthough suspension laryngoscopy (SL) is routinely used in operative laryngology, no prospectively gathered data on the complications of this procedure have so far been available. We prospectively analyzed 339 consecutive procedures for intervention-related complications. The survey included preoperative dental status and assessment of postoperative dental, mucosal, and nerve injuries. Minor mucosal lesions were found in 75% of all patients. All healed spontaneously within a few days. Dental injuries occurred in 6.5% of all patients. These were more frequent in therapeutic laryngoscopy than in diagnostic procedures (6.8% versus 6.0%). Highly significant correlations were found between dental injury rate and preoperative dental disease (p < .04) and grade of periodontitis (p <.001). Temporary nerve lesions were observed in 13 patients (9 of the lingual nerve and 4 of the hypoglossal nerve). Although minor complications frequently occur during SL, it is a relatively safe procedure with a low risk of significant morbidity.
