Abstract
Examine incidence of postoperative vocal fold (VF) hemorrhage (PVFH) in patients who underwent microscopic laryngeal surgery and type I thyroplasty and determine the long-term consequences of hemorrhage on the outcome of the surgery.
Retrospective study.
Medical records of patients from a quaternary care laryngology practice who underwent microdirect laryngoscopy (MDL) or type I thyroplasty between November 2015 and December 2018 were reviewed as a consecutive sample. MDL procedures not performed on the VF were excluded. Demographic and medical history data associated with risk of bleeding were collected, and records were reviewed for the incidence of PVFH and long-term consequences of PVFH through Voice Handicap Index-10 (VHI-10) and preoperative and postoperative videostroboscopic findings. We considered each VF surgery as one procedure. Statistical analysis was performed using chi-square analysis for categorical data and a student t test for means. A P value of 0.05 or less was considered significant.
Total 155 patients were enrolled. The patients underwent 182 MDL surgeries, (122 bilateral and 60 unilateral), and 60 Type 1 thyroplasty surgeries (13 bilateral and 47 unilateral). In the MDL group, 34 of 304 procedures (11%) resulted in VFH. In the thyroplasty group, 10 of 73 procedures (13.7%) were associated with PVFH. Bilateral MDL procedures were associated with a higher incidence of PVFH in comparison with unilateral procedures (P= 0.03), but bilateral thyroplasties were not (P= 0.33). None of the demographic factors significantly increased or decreased risk of PVFH. Comparing the difference between preoperative and 3-6 month postoperative VF mucosal function, and preoperative and 3-6 month postoperative VHI-10 in both MDL and thyroplasty groups, no statistically significant difference was found between patients who had experienced PVFH and those who had not.
This is the largest investigation into the incidence and long-term consequences of the PVFH. 11% of the patients in the MDL group experienced PVFH; the vibratory margin of the VF was involved in only 1.3%.; and 13.7 % of the procedures in the thyroplasty group resulted in PVFH. However, PVFH was not associated with significant increase in VHI-10 or decrease in VF vibratory function during 3-6 month postoperative follow-up visits. The incidence of PVFH was related significantly to postoperative phonotrauma and upper respiratory infection, but not to gender, age, history of smoking and alcohol consumption, pulmonary and cardiovascular comorbidities, or pre-existing VF varicosities or ectasias.
