Background: Transoral, minimally invasive, organ preservation surgeries are increasingly used to treat laryngopharyngeal carcinomas to avoid the toxicity associated with combined chemoradiotherapy regimens. This study investigated the efficiency, safety, and functional outcomes of using transoral robotic surgery (TORS) to perform supraglottic laryngectomy (SGL).
Methods: This was a multicenter study using a case series with planned data collection from 2009 to 2012 for patients with supraglottic squamous cell carcinomas (SCC) who underwent SGL using TORS.
Results: Eighty-four (84) of 262 patients underwent TORS for supraglottic SCC. Within 24 hours of surgery, 24% of the patients started on an oral diet. The median use of a feeding tube was 8 days for 76% of other patients. Definitive percutaneous gastrostomy feeding was necessary for 9.5% of the patients. 24% of the patients did require a tracheostomy, and the median use was 8 days. One percent (1%) of the patients had a definitive tracheostomy. Aspiration pneumonia was observed in 23% of the patients during the postoperative course, and was responsible for the death of one patient. Postoperative bleeding occurred in 18% of the patients. Based on the pathology results, 51% of the patients received adjuvant radiation therapy.
Conclusion: TORS for SGL in intermediate stage SCC is a safe procedure with good functional outcomes and fast recovery times. However, adverse events can occur. Consequently, this technique requires good patient selection criteria to reduce the risk of postoperative complications.
