Laryngeal suspension and upper esophageal sphincter myotomy as a surgical option for treatment of severe aspiration

Favourable swallowing outcomes after subtotal glossectomy with laryngeal suspension

Subtotal or total glossectomy for advanced tongue cancer has an adverse impact on swallowing. The purpose of this retrospective study was to analyse postoperative swallowing outcomes and to determine the ideal reconstruction method in these patients. The clinical and swallowing data of patients with tongue cancer who underwent subtotal glossectomy at the study institution between 2005 and 2019 were reviewed retrospectively. Data were available for 101 patients. The most common reconstruction method was a free rectus abdominis musculocutaneous flap (69 cases). The postoperative feeding tube dependency rate was 11.1% at discharge and 9.4% at 1 year. During the study period, laryngeal suspension and/or a cricopharyngeal myotomy was performed in 39 patients (38.6%), with 25 of these operations performed after 2017. Patients treated in 2017-2019 were significantly more able to take thin liquid (P < 0.001) and lost less weight (P = 0.015) compared to those treated in 2005-2016. Multivariate analysis of 61 patients who did not undergo laryngeal suspension and/or cricopharyngeal myotomy showed significant feeding tube dependency in those aged 65 years and older (P = 0.004). Thin liquid intake was significantly improved after subtotal glossectomy with laryngeal suspension, which led to better postoperative swallowing and improved quality of life.

Effect of Laryngeal Suspension and Upper Esophageal Sphincter Myotomy for Severe Dysphagia Due to Brainstem Disease

OBJECTIVES

Surgical procedure is considered in patients with severe dysphagia when conservative treatment fails. This study aimed to evaluate laryngeal suspension (LS) and upper esophageal sphincter (UES) myotomy for treating severe dysphagia due to brain disease.

METHODS

Fourteen patients underwent LS and UES myotomy, with a median follow-up of 5 years and 6 months when conservative treatment failed. The penetration-aspiration scale (PAS), the Dysphagia Severity Scale (DSS), the Eating Status Scale (ESS), and diet contents were evaluated just before surgery, at discharge, and at the last follow-up.

RESULTS

Preoperative intake was tube feeding in all patients. The patients learned the extended head and flexed neck posture to open the esophageal inlet. PAS, DSS and ESS scores, and diet contents were significantly improved at discharge compared with before surgery, and were maintained until the last follow-up. Eight patients had pneumonia during their hospital stay, and five had pneumonia between discharge and at the last follow-up. Age was significantly, negatively correlated with DSS and ESS at the last follow-up.

CONCLUSION

Although LS and UES myotomy require a long inpatient rehabilitation and the risk of pneumonia after surgery is high, the outcome is favorable and the effects last for a long time.

Position Paper of the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery and the German Society of Phoniatrics and Pediatric Audiology - Current State of Clinical and Endoscopic Diagnostics, Evaluation, and Therapy of Swallowing Disorders in Children and AdultsSwallowing disorders are frequent. The main concern is mortality due to aspiration induced pneumonia and malnutrition. On the other hand quality of life is severely affected. The demographic trend indicates an increase of dysphagia in the future. Neurodegenerative diseases, tumors of the digestive tract and sequelae of tumor treatment in the head and neck region are the main pathologic entities.Predominantly ENT physicians and phoniatrists, are asked for diagnostics and therapy who will coordinate the interdisciplinary treatment according to the endoscopic findings.A differentiated approach in history, diagnostics, and symptom oriented treatment is necessary for the mostly complex disorders. The integration of non-medical personnel such as logopeds (speech language pathologists), physiotherapists, and occupational therapists in planning and executing an effective therapy expands and completes the patient-oriented care. Conservative treatment by these therapists is an important pillar in the treatment. Parts of the specific diagnostics can be taken over by them in close cooperation.In particular an interdisciplinary cooperation with the staff from intensive care medicine is indispensable.The diagnostic procedures of specific endoscopy as described in this position paper are part of the primary and fundamental tasks of ENT specialists and phoniatrists.Endoscopy is a medical service that is basically not delegable. Consequently substitution of the physician is precluded.

Long-Term Results of Laryngeal Suspension and Upper Esophageal Sphincter Myotomy as Treatment for Life-Threatening Aspiration

Objectives:

We evaluated the long-term results of laryngeal suspension and upper esophageal sphincter (UES) myotomy in patients with life-threatening aspiration.

Methods:

In the period 1995 to 2004, 17 patients with severe aspiration caused by insufficient laryngeal elevation and absent or negligible pharyngeal constrictor muscle activity during deglutition resulting in aspiration pneumonia were surgically treated with a laryngeal suspension procedure and UES myotomy. Preoperative and postoperative videofluoroscopy was performed to assess swallowing and aspiration.

Results:

In 9 of the 17 patients, long-term (more than 1 year) full oral intake without aspiration was achieved. Three other patients demonstrated improvement of deglutition with partial restoration of oral intake with adjusted food consistency, but remained partly dependent on gastrostomy feeding for adequate nutrition. Two patients no longer had cases of aspiration pneumonia, but were unable to achieve even modified oral intake. Three patients finally underwent total laryngectomy — 2 of them after initial successful full oral intake without aspiration but with recurrent aspiration as a result of progression of neuromuscular disease. None of the patients succumbed to aspiration pneumonia.

Conclusions:

In most of our patients, life-threatening aspiration was successfully treated by UES myotomy and laryngeal suspension with restoration of oral intake.

Modern reconstruction techniques for oral and pharyngeal defects after tumor resection

Several techniques have been developed to reconstruct oral and pharyngeal defects following surgery, in order to restore function and cosmesis. These are primary closure, skin grafts, local transposition of skin, mucosa and/or muscle, regional flaps and free vascularized flaps. Because of the 'bulky', pedicled nature and problems with the donor area of locoregional flaps, and consequently frequently unsatisfactory functional results, free vascularized flaps have gained popularity during the last decade. The authors review the current options available to give physicians, who are not experienced in the field of reconstruction in the head and neck, an impression of the range of techniques available for reconstruction of oral and pharyngeal defects following tumor resection. For reconstruction of oral cavity and pharyngeal defects, fasciocutaneous (e.g. radial forearm and anterolateral thigh flaps) and myocutaneous free flaps (e.g. rectus abdominis and latissimus dorsi) have proven to be very reliable. Free vascularized osteocutaneous flaps (e.g. fibula and iliac crest) permit reconstructive options for bony defects of the mandible or maxilla that can be adapted to a variety of defects. Depending on the site, size and involved tissues of the surgical defect and patient factors, a variety of reconstructive options are available. For both soft tissue and bony defects of the upper aerodigestive tract, microvascular free flaps provide good functional outcomes.
