Indications of cricohyoidoepiglottopexy versus anterior frontal laryngectomy: the role of contralateral vocal fold spread

Closure without epiglottoplasty or tracheotomy after reconstructive frontal anterior laryngectomy

Reconstructive frontal anterior laryngectomy (RFAL) is a partial laryngeal surgery technique for resecting early-stage (T1-T2) glottic squamous cell carcinoma. Indications comprise a lesion of the anterior commissure of the larynx that cannot be adequately exposed by endoscopy, and cases in which radiotherapy is refused or contraindicated. The initial RFAL technique included epiglottoplasty. Here we propose a technique without epiglottoplasty, with the advantage of avoiding need for tracheotomy in most cases. After the first stage of surgical excision, reconstruction consists in placing a vertical brace transepiglottically and below the cricoid. The epiglottis is thus left at its original height and secured in place to prevent flapping in the pharyngolaryngeal lumen. Transverse bracing is then performed through the thyroid wings: one of the key points of this surgery is to control tension to avoid risk of stenosis. The subhyoid muscles are sutured together to achieve satisfactory sealing. This technique offers satisfying functional results and oncological control. The most frequent complications are (1) secondary tracheotomy, which can be avoided by selecting patients who require a primary tracheotomy and optimizing the seal, and (2) stenosis, which can be limited by not bringing the cartilaginous structures too close together during bracing.

Guidelines for the Surgical Management of Laryngeal Cancer: Korean Society of Thyroid-Head and Neck Surgery

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to develop clinical practice guidelines for the surgical treatment of laryngeal cancer. This Task Force conducted a systematic search of the EMBASE, MEDLINE, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to the key questions. Evidence-based recommendations were then created on the basis of these articles. An external expert review and Delphi questionnaire were applied to reach consensus regarding the recommendations. The resulting guidelines focus on the surgical treatment of laryngeal cancer with the assumption that surgery is the selected treatment modality after a multidisciplinary discussion in any context. These guidelines do not, therefore, address non-surgical treatment such as radiation therapy or chemotherapy. The committee developed 62 evidence-based recommendations in 32 categories intended to assist clinicians during management of patients with laryngeal cancer and patients with laryngeal cancer, and counselors and health policy-makers.

Evidence and evidence gaps of laryngeal cancer surgery

Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number or organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery, and transoral robotic surgery have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures. In addition to an improvement of prognosis, in recent years the preservation of function and maintenance of life quality after primary therapy of laryngeal cancer has increasingly become the focus of therapy planning. Significant late toxicity after chemoradiation has been identified as an important issue. This leads to a reassessment of surgical concepts and initiation of studies on laryngeal cancer surgery which was additionally stimulated by the advent of transoral robotic surgery in the US. Improving the evidence base of laryngeal cancer surgery by successful establishment of surgical trials should be the future goal.

Post-surgical and oncologic outcomes of frontal anterior laryngectomy with epiglottic reconstruction: a review of 68 cases

OBJECTIVE

To report post-surgical and oncological outcomes of 68 patients treated with frontal anterior laryngectomy with epiglottic reconstruction.

STUDY DESIGN

Demographic data and all information regarding histopathological grade, initial tumor stage and neck status, follow up time, postoperative complications, nasogastric tube removal time, decannulation time and recurrences were collected from the database and follow-up forms.

SETTING

All patients between 1994 and 2014 who were treated with frontal anterior laryngectomy with epiglottic reconstruction for early glottic carcinoma at Ege University Otolaryngology Clinic were included in the study.

SUBJECTS AND METHODS

Sixty-six of the patients were male and 2 were female with a median age of 57.5 years (IQR 53-63.75, range 44-75). Four patients had a tumor stage of T1a, 43 had T1b and 21 had T2. Median nasogastric tube removal time, decannulation time, overall and disease free survival rates were calculated.

RESULTS

Median nasogastric tube removal time was 10 days. Median decannulation time was 12 days. Median N/G tube removal and decannulation times were higher in T2 patients but this did not reach statistical significance (p>0.05). Median follow-up time was 68.5 months (6-222 months). Five year disease free survival was 93.5%. There were 6 oncologic failures which were salvaged with total laryngectomy, neck dissection and adjuvant radiotherapy.

CONCLUSION

According to our results, which is one of the largest reported FAL with epiglottic reconstruction series in the English literature, this procedure's local control and survival rates are high with good functional results.

Attempt to improve functional outcomes in supracricoid laryngectomy in T2b and T3 glottic cancers

The goal of this study was to compare the survival rate and functional outcome of an open partial horizontal laryngectomies, Type IIa and modified Type IIa (OPHL Type IIa and OPHL mType IIa), in treatment of moderately advanced glottic carcinoma. Retrospective analysis. 80 Patients underwent OPHL Type IIa and 27, OPHL modified Type IIa (OPHL mType IIa) between the years 2001 and 2009. Clinical staging was performed according to the UICC criteria (2002). Primary endpoints of study were recurrence rate, and 3- and 5-year survival time. Secondary endpoints were laryngeal functions: respiration, swallowing and voice. There were no significant differences within local and regional recurrence rates, organ preservation rate, 3- and 5-year specific disease survival rates between OPHL Type II and OPHL modified Type IIa. Significantly lower need for temporary (OPHL mType IIa 4/27, OPHL Type IIa 30/80) and permanent tracheostomy (OPHL mType IIa 2/27, OPHL Type IIa 16/80) was found. All but one patient (OPHL Type IIa) achieved unrestricted diet. Significantly differed social eating, this ability gained 25/27 OPHL mType IIa and 54/80 OPHL Type IIa (p < 0.05). Voice handicap index revealed a decrease in quality of life in all areas; OPHL Type IIa and OPHL mType IIa differed significantly (31 and 46 points respectively, p < 0.005). The MPT value (longest pitch) for OPHL Type IIa and OPHL mType IIa lasted 8 s and 10, respectively (p < 0.005). There was no significant difference in oncological outcomes between the two types of OPHL succeeded in the earlier extubation, thus significantly lowering the need for temporary and permanent tracheotomy and providing better long-term swallowing. Although the voice was altered in all observed OPHL patients, modified Type IIa technique proved to be superior to the Type IIa in terms of voice quality. Thus, OPHL modified Type IIa is worth promoting, as long as indications were strictly conformed.
