Oropharyngeal stenosis (OPS) is a rare postoperative complication of adenotonsillectomy that can be a source of considerable patient distress and morbidity. Circumferential scarring of the soft palate and tonsillar pillars leads to narrowing of the oropharyngeal aperture. This case report describes the novel use of bilateral buccal myomucosal flaps for the repair of postoperative OPS in a 20-year-old woman presenting with dysphagia, odynophagia, dyspnea, and intermittent hypernasal speech. Postoperatively, the patient noted immediate improvement of her symptoms. At 1-month follow-up, she noted complete resolution of her symptoms with no dysphagia, nasal regurgitation, speaking difficulty, dyspnea, or gagging. The buccal flaps were well healed and completely intact, maintaining appropriate height of the tonsillar pillars. The buccal myomucosal flap is an effective tool for numerous palatal and oropharyngeal abnormalities and, as described in this case study, is a reliable, safe, and effective technique that can be considered for the reconstruction of postsurgical OPS.
