Triple-layer laryngeal closure for intractable aspiration

Abstract

Impaired laryngeal protective function can result in intractable aspiration, which causes recurrent life-threatening pneumonia. Several surgical operations have been developed to treat intractable aspiration. In this case, we report a successful case of triple-layer laryngeal closure, which was performed in a patient with type II diabetes mellitus and nutritional failure due to intractable aspiration that had been caused by several stroke attacks. Triple-layer laryngeal closure is a unique modified technique that combines laryngotracheal separation and glottic closure operations. The method that we performed can be done more safely in patients who have higher post-operative and general anaesthesia risks.

Definitive techniques for intractable aspiration pneumonia

“…For patients with intractable aspiration who have no chance of recovery of laryngeal function surgical procedures should be definitive as laryngotracheal separation or tracheoesophageal diversion, total laryngectomy, supraglottic closure, glottic closure and triple-layer laryngeal closure [2,3]. Literature review has revealed that the supraglottic closure is also associated with a high failure rate [4].…”

Candidate's Thesis: Laryngotracheal separation in neurologically impaired children: Long‐term results

“…Ideally, surgeries to prevent entry of material into the airway should achieve seven goals: 1) Protection of the airway from soilage, 2) allow safe swallowing, 3) allow unimpeded respiration, 4) be simple to perform,5) have a minimum risk of complications, 6) allow phonation, and 7) to be potentially reversible 3, 11–14. The latter two goals are primarily based on the fact that many of these techniques were developed for adults who are impaired after a major head and neck resection or cerebrovascular accident.…”
