Abstract: The Pinotti technique is a surgical treatment for megaesophagus combining Heller esophagocardiomyotomy with anterior Dor fundoplication. The procedure relieves functional obstruction, protects the esophageal mucosa, and minimizes postoperative reflux. It involves careful dissection of the distal esophagus, preservation of adjacent nerves, myotomy of the esophageal muscle layers, and anterior wrapping of the gastric fundus over the myotomy site to create a functional lower esophageal sphincter. This approach effectively alleviates dysphagia while safeguarding mucosal integrity 1. Goal: To describe the surgical approach of a rare case of a cricopharyngeal cartilage hypertrophy associated with esophageal motor dysfunction, emphasizing the technical aspects of surgical treatment using the Pinotti-Dor technique. Case report: We report the case of a 51 year-old female patient with a dry cough, mild heartburn, progressive dysphagia, weight loss and sensation of cervical obstruction. Endoscopic evaluation revealed narrowing at the upper esophageal sphincter. Amongst the imaging studies, including barium esophagogram, demonstrated a focal thickening consistent with cricopharyngeal cartilage hypertrophy. Manometric analysis confirmed esophageal motor dysfunction. Initial diagnostic evaluations such as gastrointestinal endoscopy and chest CT scan, were unremarkable. Given the anatomical findings and symptoms, surgical intervention was indicated. The chosen surgical approach was the Pinotti-Dor technique. Discussion / Final Considerations: Cricopharyngeal cartilage hypertrophy is a rare structural abnormality of the upper esophageal sphincter that can coexist with esophageal motor disorders and pose diagnostic and surgical challenges. Careful knowledge of regional anatomy and a well-planned approach are essential. The Pinotti-Dor technique allows excellent exposure of the cricopharyngeal region while minimizing surgical risk.
