Long-term outcomes of reversal of laryngotracheal separation.

The aim of this study was to evaluate the long-term outcomes of the reversal of laryngotracheal separation (LTS) in patients who underwent extensive resection of tumors located in the upper aerodigestive tract. We performed a retrospective analysis of the medical records of eight patients who had LTS reversal. The operation was successful in six patients who were followed up for a period of 17-99 months (mean = 46.3 ± 26.2). The mean interval between LTS and surgical reversal was 16.6 ± 9.1 months. Four patients had postoperative complications: mild to moderate transient aspiration in two, tracheal stenosis in one, and severe aspiration followed by tracheal stenosis in one. In the last two cases, surgical reversal was not successful. The patients whose surgery was effective maintained oral feeding and comprehensible speech until the end of the follow-up period. We conclude that reversal of LTS is technically simple and, when successful, permits the return to oral feeding and comprehensible speech for an indefinite period of time. However, the frequency of complications and inefficacy of LTS reversal should not be overlooked.
