ABSTRACT

Soft tissue necrosis (STN) is a late toxicity after radiotherapy. Extensive tissue defects due to STN near the carotid artery, such as in the lateral oropharyngeal wall, may lead to infectious pseudoaneurysms associated with fatal bleeding. Such defects are usually treated with transcervical reconstructive surgeries, which are highly invasive and technically difficult. We report a case in which a buccal fat pad (BFP) flap was used for minimally invasive transoral repair of tissue defects due to radiation-induced STN in the lateral oropharyngeal wall. The BFP flap covered the tissue defect, and the wound epithelialized completely. The patient had no dysfunctional mouth opening, speech, or swallowing. The BFP flap can be easily harvested via a minimally invasive transoral approach and is expected to be further utilized for radiation-induced STN in the lateral oropharyngeal wall.

ABSTRACT

OBJECTIVE: End-flexible-rigidscopic transoral surgery (E-TOS) is a new and minimally invasive transoral surgery for resection of Tis-selected T3 pharyngolaryngeal cancers. We evaluated long-term oncological outcomes and whether postoperative voice and swallowing function were preserved following E-TOS. METHODS: In this retrospective single-center study, 154 patients treated with E-TOS using a curved retractor, flexible-tip rigid endoscope, and thin curved instruments were included. Their survival rate, larynx preservation rate, and disease control rate were estimated using the Kaplan-Meier method. Postoperative voice function was evaluated using both objective and subjective tests. Postoperative swallowing function was assessed using the Hyodo score and the functional outcome swallowing scale. RESULTS: The 3-year and 5-year overall survival, disease-specific survival, disease-free survival, laryngectomy-free survival, local control, and loco-regional control rates post E-TOS were 89.8% and 82.2%, 95.6% and 92.3%, 78.5% and 70.3%, 87.2% and 80.9%, 93.9% and 92.5%, and 87.2% and 85.7%, respectively. Both objective and subjective postoperative voice and swallowing function tests were within normal limits in more than 90% of the patients. CONCLUSION: E-TOS is an effective, safe, low-cost, and minimally invasive transoral surgery for Tis-selected T3 pharyngolaryngeal cancer; it also preserves postoperative voice, larynx, and swallowing function.
