Voice rehabilitation after near-total laryngectomy

Near-total laryngectomy provides oncologic control of hypopharyngeal and laryngeal cancers that are not amenable to conservation procedures. The resulting myomucosal shunt provides a prosthesis-free method of voice rehabilitation. This review presents indications, technique, and speech rehabilitation for a near-total laryngectomy.     

The functional and oncologic effectiveness of near-total laryngectomy

PURPOSE: To investigate the oncologic efficiency of near-total laryngectomy for advanced laryngeal and neighboring organ cancers and to evaluate the functional results. MATERIALS AND METHODS: A retrospective review of 135 cases of near-total laryngectomy carried out in a tertiary university hospital between 1989 and 2000 was undertaken. The original operation was carried out in 3 groups: classic "near-total laryngectomy" for endolaryngeal lesions; "near-total laryngectomy and partial pharyngectomy" for lesions originating from the pyriform sinus or lesions with extension to the pharynx or tongue base but reconstructed primarily; and "near-total laryngopharyngectomy" for lesions requiring pedicled flap reconstruction after resection. Oncologic success was evaluated according to the location and extent of the tumor and the particular operation. Functional outcome was evaluated according to phonation and its quality as well as to the severity of aspiration. RESULTS: Of the 135 cases, 121 were men, and 14 were women (age range, 33-80 years; mean, 56.2 years). Mean phonation time was 35.2 days, and mean onset of oral intake was 18.5 days. Of the 135 cases of the series, 124 were evaluated for survival. Thirteen of 26 (50.0%) cases of T2, 34 of 53 (64.2%) cases of T3, and 33 of 45 (73.3%) cases of T4 carcinomas survived by the end of the evaluation period. Likewise, 46 of 77 (59.7%) cases of N0, 16 of 19 (84.2%) cases of N1, and 18 of 27 (66.7%) cases of N2 survived the same period; however, none with N3 metastatic neck disease survived. The probability of survival with regard to the T and N stages of the disease did not reveal a statistically significant result (P =.15 and.49, respectively). CONCLUSIONS: According to these results, near-total laryngectomy is a valid alternative for extended laryngeal and neighboring organ cancers with an acceptable morbidity and a high success rate for voice preservation. Near-total laryngectomy should be offered as a surgical treatment alternative for these patients.     

Electrolaryngography in near-total laryngectomy with myo-mucosal valved neoglottis

Near-total laryngectomy with myo-mucosal valved neoglottis is the most recent of the various surgical procedures for speech rehabilitation. The site and mechanism of phonatory function of the neoglottis has been investigated in eight patients by means of electrolaryngography. Results demonstrate substantial similarity in the nature of function of the neoglottis when compared with the normal human glottis.     

Comparative study of vocal function after near-total laryngectomy.

OBJECTIVES: To assess vocal function after near-total laryngectomy (NTL) and to compare that with after vertical hemilaryngectomy (VHL), both of which use the laryngeal mucosa as the vibratory tissue. STUDY DESIGN: We retrospectively evaluated 29 patients, 11 of whom underwent NTL and 18 of whom underwent VHL. However, 2 patients failed to speak and 1 patient's voice sample was lost following NTL, so we analyzed the voices of 8 patients who underwent NTL and 18 patients who underwent VHL. METHODS: Vocal function was examined by acoustic and aerodynamic analysis. Acoustic analysis involved the evaluation of pitch, intensity, pitch perturbation quotient, amplitude perturbation quotient, and normalized noise energy. In aerodynamic analysis, we studied the mean airflow rate, vocal efficiency index (alternating current/direct current [AC/DC]), and maximum phonation time. RESULTS: Vocal function except pitch after either NTL or VHL had much variability, but the results following each procedure did not differ significantly. CONCLUSIONS: There are no significant differences between vocal function following NTL and VHL. Fiberscopic examination of the mucosa of the arytenoid was observed to vibrate in patients who underwent NTL, so that the phonatory mechanism after NTL resembled that after VHL.     

Aspiration and speech shunt stenosis in near-total laryngectomy patients

A near-total laryngectomy or near-total laryngopharyngectomy with the creation of a speech shunt was carried out on 66 laryngopharyngeal cancer patients. Intelligible shunt speech was obtained in 50 patients (76%), while stenosis of the shunt occurred in 13 patients (20%), and asymptomatic aspiration in 4 (6%). Poor voice production was usually due to shunt stenosis, a fibrotic band surrounding the shunt, or local recurrence of tumor. Perioperative wound infection and postoperative irradiation did not interfere with the developement of shunt speech. In 12 patients with shunt stenosis, revision surgeries were performed to augment the shunt openings. During these procedures, the stenotic shunt was opened and a silastic tube was introduced into the shunt lumen to serve as a stent. For the moderately to severely stenotic shunt, the mucosal defect present was covered with a free skin graft or a sternocleidomastoid myoperiosteal flap. Following treatment, results demonstrated that 10 of the 12 patients acquired satisfactory shunt speech. In two unsuccessful cases, the causes of failure were wound infection and graft necrosis and were presumed to be complications of previous irradiation.Presented in part at the 3rd European Congress of the European Federation of Oto-Rhino Laryngological Societies.

喉切除术后咽瘘的预防和治疗

目的 本文讨论了减少喉切除术后咽瘘发生的外科技巧和围手术期处理。方法 共对365例经由喉全切除术和喉大部分切除术治疗的喉恶性肿瘤病例的临床资料进行分析,其中喉全切除术333例,喉大部分切除术32例。结果 365例喉切除术后28例发生咽瘘,发生率为7.7％;其中喉全切除术后27例发生咽瘘,发生率8.1%;喉大部分切除发音管重建术后1例发生咽瘘,发生率3.1％。结论 采用喉咽食管黏膜分层缝合方式,以及术后颈部持续负压引流对于降低咽瘘发生率关系密切。喉大部分切除发音管重建术的咽瘘发生率低于喉全切除术,可能与喉大部分切除保留一侧梨状窝黏膜,喉咽黏膜缺损较小有关。
