    Computed tomography (CT) scans help identify normal healing after vertical hemilaryngectomy and detect recurrent laryngeal cancer. CT imaging is valuable for assessing postoperative changes and planning further treatment.

    Area of Science:

    • Otolaryngology
    • Radiology
    • Oncology

    Background:

    • Vertical hemilaryngectomy is a surgical procedure for laryngeal cancer.
    • Postoperative assessment is crucial for detecting recurrence.
    • Computed tomography (CT) is a key imaging modality in head and neck oncology.

    Purpose of the Study:

    • To define the normal CT appearance of the larynx after vertical hemilaryngectomy.
    • To evaluate the utility of CT in identifying recurrent laryngeal neoplasm.
    • To correlate CT findings with clinical and laryngoscopic examinations.

    Main Methods:

    • Retrospective analysis of CT scans from 22 patients post-vertical hemilaryngectomy.
    • Comparison of imaging findings in patients with and without recurrent neoplasm.

  • Correlation of CT findings with clinical status and laryngoscopy.

    • Main Results:

    • Normal postoperative changes include loss of preepiglottic fat, aryepiglottic fold changes, vocal cord convexity, and cartilage regeneration.
    • Recurrence signs on CT include vocal cord widening, pseudocord convexity, subglottic tumor, and extralaryngeal masses.
    • CT findings can be mimicked by granulation tissue, hyperkeratosis, or inclusion cysts, necessitating careful interpretation.

    Conclusions:

    • CT provides valuable insights into normal postoperative changes following vertical hemilaryngectomy.
    • CT plays a significant role in detecting and staging recurrent laryngeal cancer.
    • CT imaging aids in treatment planning by assessing the extent of tumor or postoperative changes.
