Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Horizontal glottectomy (HG) for laryngeal cancer yields a dysphonic voice, but patients perceive minimal disability. Long-term voice results show preserved oral communication despite objective vocal impairments after HG surgery.

Area of Science:

  • Otolaryngology
  • Speech-Language Pathology
  • Oncology

Background:

  • Horizontal glottectomy (HG) is a surgical option for select laryngeal cancers.
  • Evaluating long-term voice outcomes post-HG is crucial for patient quality of life.

Purpose of the Study:

  • To assess long-term voice results in patients who underwent horizontal glottectomy.
  • To correlate objective vocal parameters with subjective patient self-assessment.

Main Methods:

  • Included 16 patients with prior HG surgery (≥1 year).
  • Evaluations comprised laryngoscopy, perceptual voice rating (GRBAS scale), maximum phonation time (MPT), spectrography, perturbation analysis, and Voice Handicap Index (VHI).

Main Results:

  • Endoscopy revealed preserved arytenoid mobility but impaired neoglottis vibration.

  • Objective measures indicated dysphonia (mean GRBAS: 2.7, MPT: 8.2s, Jitter%: 6.5, Shimmer%: 13.9).
  • Subjective VHI scores were moderate (mean 35.8), suggesting preserved oral communication despite vocal changes.

    • Conclusions:

    • Horizontal glottectomy results in objective vocal impairments.
    • Patients report a low degree of perceived disability, indicating functional oral communication is maintained.
    • Long-term voice quality after HG requires comprehensive objective and subjective assessment.
