Transoral laser microsurgery for managing laryngeal stenosis after reconstructive partial laryngectomies.
To retrospectively analyze our experience of transoral laser microsurgery (TLM) for treating postoperative laryngeal obstruction (POLO) after supracricoid and supratracheal laryngectomy (open partial horizontal laryngectomy [OPHL]) types 2 and 3, and to investigate potential relationships between patients' clinical features and their functional outcomes.



A retrospective cohort study.



The prognostic influence of clinical and surgical parameters on functional outcomes was investigated in a univariate statistical setting in terms of decannulation rate (DR), time to tracheostomy closure (TTC), and number of laser procedures required (NLP).



OPHL type 2 was associated with a better functional outcome than OPHL type 3 in terms of DR, TTC, and NLP (P = .03, P = .02, and P = .02, respectively). Annular and semicircumferential stenoses developed more frequently after OPHL type 3, and were particularly difficult to manage with TLM. Fixation of the residual arytenoid was a negative prognostic factor in terms of functional outcome in terms of DR, TTC, and NLP (P = .0002, P = .08, and P = .08, respectively).



There is no standardized laser treatment for POLO; it must be tailored to individual patients. Identifying prognostic factors influencing functional outcome could help surgeons to earmark patients less likely to benefit from TLM for the treatment of POLO, and enable an adequate preoperative counseling, given the high probability of repeat postoperative TLM procedures.
