Supracricoid laryngectomy with cricohyoidopexy (CHP) in the treatment of laryngeal cancer: A functional and oncologic experience

Subtotal laryngectomy with cricohyoidopexy (CHP) results in a satisfactory cure rate in selected T1b, T2, and T3 supraglottic and glottic cancers. The clinical, oncologic, and functional results of this type of surgery have led to an ever-increasing number of patients undergoing this procedure. This study involved 70 patients operated on from 1984 to 1993 using this surgical procedure. This report also discusses the clinical (cTNM) and pathologic (pTNM) classifications of CHP cases. Fifty-two of these patients were evaluated after a follow-up of more than 3 years. Lymph node treatment protocol comprised 51 functional ipsilateral neck dissections (FNDs), 9 bilateral FNDs, 1 radical ipsilateral dissection, and 1 radical ipsilateral and contralateral FND. There were 6 recurrences (5 local, 1 neck); after CHP physiologic deglutition was recovered in most of the patients (95.5%), and all but 6 (92%) mere decannulated. Results were excellent after phoniatric rehabilitation. This surgical procedure may be indicated for selected laryngeal cancers and allows for the preservation of laryngeal functions even when the neoplastic lesions are advanced. However, care must be taken when evaluating the infiltration of the paraglottic space, as that infiltration represents the main cause of failure in this type of surgery.
