Submucosal cordectomy for laryngeal stenosis

Submucosal cordectomy, an old procedure first described for the treatment of bilateral abductor vocal cord paralysis, was used to relieve glottic or minimal subglottic stenosis in four patients. Three attained adequate airways with no further procedures; one required subsequent dilations for granulation tissue after which decannulation was successfully effected. Although airway restoration has been successful, the resultant voice has been poor, poorer than that usually achieved with arytenoidectomy. When cricoarytenoid scarring precludes arytenoidectomy and lateral vocal cord fixation, an adequate laryngeal lumen can be restored with submucosal cordectomy if sufficient laryngeal cartilage support remains.

Posterior glottic stenosis

Posterior glottic stenosis in children is not uncommon and must be differentiated from vocal cord paralysis when there is posterior glottic fixation. Procedures aimed at increasing the airway lumen by tissue excision have not been uniformly successful. Chronic aspiration and poor voice results have been reported. Expansion of the posterior glottis yields excellent results. Tracheotomy decannulation without aspiration and return of vocal cord mobility in children who have vocal cord fixation with achievement of a functional voice can be expected from widening the laryngeal framework. Scar incision without excision reduces the denuded laryngeal surface. The laryngeal framework is widened by anterior and posterior cricoid split and by stenting. Posterior cartilage grafting reduces scar tissue build-up and the duration of stenting.     

Laryngeal Compensation for Voice Production After CO2 Laser Cordectomy

Objectives

Carbon dioxide (CO₂) laser cordectomy is considered one of the modalities of choice for treatment of early glottic carcinoma. In addition to its comparable oncological results with radiotherapy and open surgical procedures, it preserves of laryngeal functions including voice production. The aim of this study was to detect how the larynx compensates for voice production after different types of CO₂ laser cordectomy for early glottic carcinoma together with assessment of the vocal outcome in each compensation mechanism.

Methods

One hundred twelve patients treated with CO₂ laser cordectomy were classified according to their main postoperative phonatory site. Perceptual analysis of voice samples using GRBAS (grade, roughness, breathiness, asthenia, and strain) scale was done for 88 patients after exclusion of the voice samples of all female patients to make the study population homogenous and the samples of 18 male patients due to bad quality (4 patients) or unavailability (14 patients) of their voice samples and the results were compared with those obtained from control group that included 25 age-matched euphonic male subjects.

Results

Five types of laryngeal compensation were defined including: vocal fold to vocal fold, vocal fold to vocal neofold, vocal fold to vestibular fold, vestibular fold, to vestibular fold, and arytenoids hyper adduction. Characters changes of voice produced by each compensation type were found to be statistically significant except for breathiness, asthenia and strain changes in vocal fold to vocal fold compensation type.

Conclusion

The larynx can compensate for voice production after CO₂ laser cordectomy by five different compensation mechanisms with none of them producing voice quality comparable with that of controls.

双侧声带麻痹不同术式治疗前后声门测量及嗓音评价

目的探讨3种不同的双侧声带麻痹治疗术后声门面积及嗓音质量。方法 46例双侧声带麻痹患者分别采用激光杓状软骨切除术(A 组24例),膈神经替代喉返神经吻合术(B 组9例),喉外径路杓状软骨切除声带外移固定术(C 组13例)治疗,手术前后行声门测量及嗓音分析。结果 A、B、C 组拔管率分别为91.7%(22/24)、88.9%(8/9)、100.0%(13/13),3种术式术后最大开放声门面积平均(x±s)分别为:(47.2±7.4)mm~2、(78.3±16.0)mm~2、(48.1±6.5)mm~2。B 组术后声门面积明显大于 A、C 组,差异有统计学意义(t 值分别为4.46和3.85,P 值分别为0.000和0.001)。A、C 组术后声门面积差异无统计学意义(t=1.68,P=0.101)。A 组术后17例能保持术前的嗓音质量,7例恶化;B 组术后5例嗓音好转,1例恢复正常,3例无变化;C 组术后3例嗓音无变化,10例恶化。B 组9例术后膈神经修复侧膈肌均麻痹不动,肺活量及最大呼吸容量为术前的72%～84%及76%～84%;半年后膈肌动度恢复达35%～76%,肺活量及最大呼吸容量为术前的93%～97%及91%～98%。结论膈神经替代吻合术后拔管患者声门面积最大,嗓音最好。激光杓状软骨切除和喉外径路杓状软骨切除声带外移固定术均能建市足够气道,拔除气管套管,但前者嗓音明显优于后者。     

Early-stage glottic cancer: oncological results and margins in laser cordectomy

OBJECTIVES: To assess local control of early-stage glottic cancer by laser cordectomy in comparison with previously published external partial laryngectomy series and to determine the relevance of histological margins in glottic cancers excised with laser cordectomy. DESIGN: Retrospective review of laser cordectomy for carcinoma in situ (Tis) and stage T1 glottic cancer from January 1991 to January 2004. SETTING: University hospital. PATIENTS: Fifty-two patients with Tis or T1 glottic cancer. INTERVENTION: Endoscopic laser cordectomy, classified using the system proposed by the European Laryngeal Society Working Committee. MAIN OUTCOME MEASURES: Local control after initial surgery and after salvage compared with a published historical control group, according to the type of cordectomy performed and the histological margins of the removed specimen. RESULTS: Sixteen patients with Tis, 30 with T1a tumors, and 6 with T1b tumors were followed up for an average of 38 months. Type I cordectomy was the most common procedure used to treat Tis, and type II and type III were the most common for treating T1a and T1b tumors. Of 6 recurrences, 4 were treated with laser cordectomy and 2 were treated with external partial laryngectomy. The rate of laryngeal preservation was 100%. There were 3 recurrences despite histologically clear margins. Three (17%) of 18 patients with suspicious margins developed recurrences. The rate of local control with single intervention (46 [89%] of 52) was lower than with partial external laryngectomy. However, 46 (89%) of 52 patients ultimately had less tissue removed by laser than would have been removed by external partial laryngectomy. CONCLUSIONS: Laser cordectomy provides excellent local control and laryngeal preservation. Close follow-up of patients with positive or suspicious margins is an alternative to further routine treatment.     

Laser resection of T1a glottic carcinomas: results and postoperative voice quality

OBJECTIVES: To calculate recurrence, mortality and complication rates and evaluate postoperative voice quality after laser resection of T(1a) glottic carcinoma. MATERIAL AND METHODS: Since 1995 we have treated 118 patients with a T(1a) glottic carcinoma with laser surgery. In order to evaluate postoperative voice quality, patients who were alive and free of recurrence were sent the Voice Handicap Index (VHI) questionnaire containing 30 questions concerning how their voice affects their daily life physically, emotionally and socially. RESULTS: Twelve patients (10%) had a local recurrence and received further treatment, either a second laser treatment, radiotherapy or a total laryngectomy. One patient (0.84%) died due to the laryngeal cancer. Ninety-nine patients were sent the VHI questionnaire and 94 of the completed questionnaires were included in the study and analyzed. The mean total score was 13.2, with mean subscores of 6.5 (physical), 4.1 (functional) and 2.5 (emotional). CONCLUSIONS: The results indicate that these patients as a group do not consider that their voice has a negative impact on their daily life. Good surgical technique is essential to obtain a good functional result. The laser strength should be kept low and the surgical margins small in order to minimize scarring and vocal cord stiffness.     

Diode laser surgery in the endoscopic treatment of laryngeal paralysis

Several surgical procedures have been proposed for the treatment of respiratory distress secondary to bilateral vocal cord paralysis. The aim of all surgical techniques used is to restore a glottic lumen sufficient to guarantee adequate breathing through the natural airway, without tracheotomy and preserving an acceptable phonatory quality. In this study we present our experience from 1998 to 2004 concerning the use of the diode contact laser for a modified Dennis-Kashima posterior endoscopic cordectomy (extended to the false homolateral chord in 3 cases and to the homolateral arytenoid vocal process in 6 cases). 18 patients (15 male, 3 female) were treated; the age range was 35-84 years. The etiology of paralysis varied: iatrogenic post-thyroidectomy and post-thoracic surgery in 5 cases (28%), post-traumatic in 2 cases (11%), secondary to a central lesion in 11 (61%). The operation was carried out with a diode contact laser (60W; 810 nm). Follow-up was 20 months. Dyspnea improved in all patients; the 9 tracheostomized patients were decannulated within 2 months after surgery. Final voice quality was subjectively good in 16 patients (88%). None of patients had any complications after surgery. In conclusion, the endoscopic posterior cordectomy performed by contact diode laser is an effective and reliable method for the treatment of dyspnea secondary to bilateral laryngeal paralysis, guaranteing a sufficient airway without impairing swallowing and maintaining acceptable voice quality.
