Supracricoid partial laryngectomy as salvage surgery after radiation failure.

Radiotherapy is often chosen as the definitive treatment for early stage laryngeal carcinoma. Total laryngectomy is the main procedure for failures. Endoscopic treatment of recurrences by CO(2) laser has found limited application. Partial laryngectomy through an external approach has been proposed as salvage surgery, and the vertical partial laryngectomy (VPL) is the most mentioned surgical technique in the literature, although there are, to date, very few reports regarding the use of the supracricoid partial laryngectomy (SCPL) as salvage surgery after radiation failure. The aim of the study is to check the feasibility of SCPL with cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP) in patients with laryngeal recurrence after radiation failure and to evaluate the oncologic results, morbidity, and functional outcome. Fifteen consecutive patients were treated with salvage intent by SCPL from January 1992 to December 1998. CHEP and CHP were performed in 11 and 4 patients, respectively. Five patients underwent homolateral surgical neck dissection, and one underwent bilateral neck dissection. All patients had a temporary tracheostomy, and two patients required percutaneous endoscopic gastrostomy (PEG) to ensure feeding. Functional rehabilitation started 2 weeks after the operation. The results have been evaluated in terms of oncologic outcome and functional preservation. Twelve patients are alive with a minimum follow-up of 36 months and 3 patients died after 36 days, 6 and 14 months after surgery, the first and second patient from heart failure and the third from lung metastasis. Respiratory function was recovered in all cases. Oral intake began 12 days after surgery, and in 14 cases satisfactory swallowing was recovered 30 days after surgery. An acceptable quality of the voice was achieved by most patients, and a high rate of local immediate complications was solved in all cases. SCPL represents an effective technique as salvage treatment of laryngeal cancer after exclusive radiotherapy; there is a good functional recovery with acceptable morbidity and good oncologic long-term control.

Subtotal laryngectomy Cricohyoidoepiglottopexy: Surgical procedure and technical tips

Cricohyoidoepiglottopexy (CHEP) is indicated for early stage and selected advanced stage laryngeal cancers. In this subtotal laryngeal surgery, thyroid cartilage is removed along with its intrinsic tissues leaving single or both arytenoids. The laryngeal defect is closed by approximat-ing and fixing the cricoid cartilage to the hyoid bone. Surgical procedure and technical tips are presented. Care must be taken to avoid recurrent laryngeal nerve injury during resection adjacent to the inferior horn of the thyroid cartilage. The surgical margin must be perfectly clear during the resection around arytenoids. The laryngeal defect must be sufficiently closed by approximating and fixing the cricoid cartilage to the hyoid bone to avoid cervical infection. These are three major points which might affect the surgical outcome.

Laryngeal preservation with supracricoid partial laryngectomy results in improved quality of life when compared with total laryngectomy.

Study 1: To assess the oncologic outcome following supracricoid partial laryngectomy (SCPL). Study 2: To compare the quality of life (QOL) following SCPL to total laryngectomy (TL) with tracheoesophageal puncture (TEP). Study 3: To analyze whole organ TL sections to determine the percentage of lesions amenable to SCPL STUDY DESIGN: Study 1: A retrospective review of patients who underwent SCPL. Study 2: A non-randomized, prospective study using QOL instruments to compare patients who underwent either SCPL or TL Study 3: A retrospective histopathologic study of TL specimens assessed for the possibility of performing an SCPL. Study 1: Twenty-five patients with carcinoma of the larynx underwent SCPL between June 1992 and June 1999. Various rates of oncologic outcome were calculated. Study 2: Thirty-one patients participated in the QOL assessment. This included the SF-36 general health status measure, the University of Michigan Head and Neck Quality of Life (HNQOL) instrument, and the University of Michigan Voice-Related Quality of Life (VRQOL) instrument. Study 3: Ninety surgical specimens were obtained and studied from the total laryngectomy cases in the Tucker Collection. Multiple sites were evaluated for the presence of carcinoma A computer program was written to classify whether the patient was amenable to SCPL. Study 1: The overall local control rate was 96% (24/25). The local control rate following SCPL with cricohyoidoepiglottopexy (CHEP) was 95% (20/21). The local control rate following SCPL with cricohyoidopexy (CHP) was 100% (4/4). Study 2: The SCPL had significantly higher domain scores than TL and TEP in the following categories for the SF-36: physical function, physical limitations, general health, vitality, social functioning, emotional limitations, and physical health summary. The significantly higher domains for the SCPL when compared with the TL and TEP for the HNQOL were eating and pain. Finally, when voice-related QOL was assessed with the V-RQOL, the domains of physical functioning and the total score were significantly better with SCPL when compared with TL and TEP. Study 3: Forty of 90 (44%) laryngeal whole organ specimens were determined to be resectable by SCPL. In 16 (18%) specimens, the patients could have undergone SCPL with CHEP and in 24 (27%) specimens the patients could have undergone SCPL with CHP. Among the 40 (44%) specimens determined to be able to have undergone SCPL, 19 were glottic (1 T1, 15 T2, 3 T3) and 21 were supraglottic (9 T2, 12 T3). 1) A review of the literature and an analysis of the data in this study indicate that excellent local control may be expected following SCPL. 2) The QOL following SCPL, as measured by three validated QOL instruments, is superior to TL with TEP. 3) A histologic assessment of whole organ sections of TL specimens indicates that many patients who have been subjected to TL may have been candidates for SCPL. 4) If the indications and contraindications are rigorously adhered to, SCPLs are reasonable alternatives to TL in selected cases.

Cricohyoidoepiglotto-pexy (CHEP) and Cricohyoido-pexy (CHP) are indicated for early stage and selected advanced stage laryngeal cancers. In this subtotal laryngeal surgery, thyroid cartilage is removed along with its intrinsic tissues leaving both arytenoids. The laryngeal defect is closed by approximating and fixing the cricoid cartilage to the hyoid bone.Between 1997 and 2000, four patients received CHEP and one patient received CHP at our institute. The average admission dates were 110 days. Decanulation and initiation of swallowing rehabilitation were achieved at a mean of 22 and 40 post-operative days respectively. All patients acquired breathy but satisfactory vocal function shortly after surgery. Three patients obtained excellent swallowing function after 1 month of intense rehabilitation. Two patients still have some difficulty with liquid foods. The clinical and technical problems, which might affect the postoperative course, are discussed in detail.

Supracricoid partial laryngectomies: Oncologic and functional results

Background The authors present their study on oncologic and functional results of supracricoid partial laryngectomies (SPL) performed on 149 patients between January 1984 and December 1995. Methods Cricohyoidopexy (CHP) was carried out on 98 patients and cricohyoidoepiglottopexy (CHEP) on 51 patients. The patients were divided into two groups. The first group included those operated on between January 1984 and December 1992 and who therefore had a minimum follow-up period of 3 years. The second group included those operated on after December 1992 and who therefore had a follow-up period of less than 3 years. The statistical evaluation of this second group was carried out using an actuarial method according to Kaplan-Meier. Results In the first group, survival rate (regarding disease-related deaths) was 94% (95/101), whereas in the second group, survival rate was 95%. There were 9 recurrences in the 149 patients (6.71%), 8 of which occurred after CHP (6 for tumor [T] and 2 for node [N]) and 1 (for T) after CHEP. Three of the 6 recurrences for T after CHP occurred in the hypopharynx, 2 in the peristomal area, and 1 in the arytenoid area. The only recurrence for T after CHEP occurred in the paraglottic area. Decannulation was carried out in 85.7% of CHP patients (84/98) and in 98% of CHEP patients (50/51). The nasogastric tube was kept in position for an average of 28 days (range, 15–90 days) in the CHP patients and 15 days (range, 9–90 days) in the CHEP patients. Swallowing was excellent; only a small number of patients (n = 21) were forced to assume a particular posture during meals. Phoniatric controls performed on 104 patients also showed adequate speech recovery. Conclusions If the indications are applied scrupulously, CHEP is a valid alternative to partial laryngeal surgery and CHP is a possible alternative to total laryngectomy in the treatment of glottic and supraglottic tumors. © 1998 John Wiley & Sons, Inc.

Cricohyoidoepiglottopexy for glottic carcinoma with fixation or impaired motion of the true vocal cord: 5-year oncologic results with 112 patients.

The medical charts and operative files of 112 patients (combined inception cohort) with well to moderately differentiated invasive glottic squamous cell carcinoma presenting fixation (22) or impaired motion (90) of the true vocal cord (TVC) consecutively treated with cricohyoidoepiglottopexy (CHEP) at our institutions from 1972 to 1989 were retrospectively reviewed. A minimum 5-year follow-up was always achieved. The Kaplan-Meier 5-year actuarial survival, local recurrence, nodal recurrence, distant metastasis, and metachronous second primary tumor estimate for the entire group of patients were 84.7%, 5.4%, 6.4%, 1.2%, and 10.8%, respectively. The 5-year absolute and cause-specific survival rates were 85.5% and 94.1% for patients with fixation of the TVC and 81.3% and 96% for patients with impaired motion of the TVC. The 5-year actuarial local control rates for patients with fixation or impaired motion of the TVC were 95.4% and 94.4%, respectively. Local recurrence was statistically more likely in patients with positive margins (p = .007). Nodal recurrence was statistically more likely in patients with local recurrence (p = .005). Permanent tracheostomy related to postoperative laryngeal stenosis was requested in 2 patients. Aspiration-related completion total laryngectomy and/or permanent gastrostomy were never requested. Overall, local control and laryngeal preservation were achieved in 97.3%, and 95.5% of patients, respectively. At our institutions, the change from the conservative treatment modalities of radiotherapy and vertical partial laryngectomy to CHEP has brought about an increase in long-term survival, local control, and laryngeal preservation rates when compared to historical controls using vertical partial laryngectomy or radiotherapy.
