Reconstruction technique following total laryngectomy affects swallowing outcomes

Associations between hypopharyngeal defect closure and quality of life in long-term total laryngectomy survivors

BACKGROUND

Few studies have examined health-related quality of life (HRQOL) outcomes in long-term total laryngectomy survivors in relation to the type of hypopharyngeal defect.

METHODS

A cross-sectional study was performed in long-term total laryngectomy survivors, treated between 2000 and 2020. The primary outcome was HRQOL, assessed using the FACE-Q Head and Neck Cancer Module, in relation to the type of hypopharyngeal closure (primary closure, partial or circumferential reconstruction).

RESULTS

Seventy-nine survivors were included with a median follow-up of 92.1 months (IQR 75.6-140.2 months). Patients requiring partial hypopharyngeal reconstruction (n = 18) scored significantly worse than patients with primary closure (n = 51) on 4 of 13 FACE-Q domains: functional domains of eating (p = 0.03), speech (p = 0.05), and swallowing (p = 0.03), and the psychological domain of speaking-related distress (p = 0.02). No statistically significant differences were found between the circumferential hypopharyngeal defect reconstruction group (n = 10). Stricture occurrence was the only clinical factor associated with worse eating, speaking, swallowing, eating-related distress, and cancer worry in multivariable analyses.

CONCLUSION

Several functional and psychological domains were significantly worse following partial hypopharyngeal reconstruction than in patients who received primary closure. Efforts to reduce stricture rates to enhance reconstructive outcomes following total laryngectomy merit further research.

Swallowing after total laryngectomy surgery: where are we after 150 years?

Purpose of review

Recent findings

Dysphagia is a common sequela following total laryngectomy surgery; however, there is significant variability in its assessment and management. Manometry enables an accurate understanding of the underlying mechanism of dysphagia and precise assessment of any oesophageal dysfunction. EndoFLIP is a useful tool to better understand dysfunction of the upper oesophageal sphincter particularly to detect stricture.

Summary

Following total laryngectomy surgery, dysphagia is common; clinicians need to be alert to early indicators of dysfunction and understand the tools to comprehensively characterize swallow function. Accurate diagnosis of a stricture is important, as this aspect of dysfunction can be modified, and may alleviate surrogate problems such as a leaking voice prosthesis. Clinicians should have a low threshold to examine patients for oesophageal dysfunction due to the high prevalence of dysmotility following a laryngectomy.

Functional Oral Intake in Primary Versus Salvage Laryngectomy

OBJECTIVE

Advanced-stage laryngeal squamous cell carcinoma is treated with primary surgery or chemoradiation. We aim to determine if there are differences in postoperative functional oral intake in primary (PL) versus salvage laryngectomees (SL).

STUDY DESIGN

Retrospective cohort study.

SETTING

Patients who underwent laryngectomy between 2011 and 2021.

METHODS

We examined demographic, diagnostic, treatment, and swallow function data pre- and postoperatively. A follow-up survey was distributed to assess current swallow status.

RESULTS

One hundred twenty-five patients were included. Preoperatively, 68.8% of patients reported dysphagia. Median functional oral intake score (FOIS) was 4.0 [interquartile range, IQR: 1.0-6.75]. The SL group had lower preop FOIS [2.0; IQR: 1.0-4.75] that did not reach significance compared to the PL group [4.5; IQR: 1.0-7.0] (P = .052). 73.4% of patients had a feeding tube. The PL group was more likely to have the tube removed [odds ratio, OR: 2.4; confidence interval, CI: 1.0-5.7]. The SL group was more likely to require feeding tube placement more than 6 months postop [OR: 6.9; CI: 1.65-32.6]. SL FOIS scores improved by 3 months postop to 5 (SL ΔFOIS = 3, P = .0150). PL scores improved to 7 [PL ΔFOIS = 2, P = .0005] at 12 to 15 months. Sixty-nine patients were contacted for a follow-up survey and 16 completed this survey. 30.4% patients reported dietary restrictions (mean 4.4 years postop).

CONCLUSION

Patients undergoing SL appear to obtain similar swallow outcomes compared to PL at 3 to 6 months postlaryngectomy, but plateau. The PL group continues to improve up to 1 year postoperatively. Fifty percent of patients report on-going dysphagia after 5 years.

Postlaryngectomy pharyngoplasty with melolabial flap

To the best of our knowledge, this is the largest case series describing the use of a melolabial flap for postlaryngectomy pharyngoplasty. It is an excellent alternative for pharyngoplasty, especially in cases post chemoradiotherapy. It accomplishes the goal while removing the restrictions of local and distant flaps. Although donor site morbidity is acceptable, specific consent is required due to the possibility of functional and cosmetic impairment. Additional cases with a larger sample size and a longer follow-up period can assist corroborate our first findings. In addition, because we tend to protect facial vessels for this flap, a follow-up about the compromise of oncological safety at level IB is required. In our case series, however, there was no recurrence until the final follow-up. As a result, it is a better option to pharyngoplasty post laryngectomy.

Reconstruction of Partial Hypopharyngeal Defects following Total Laryngectomy: A Systematic Review and Meta-Analysis

BACKGROUND

Various operative techniques exist to reconstruct partial hypopharyngeal defects following total laryngectomy. The current study aimed to investigate and compare complications and functional results following commonly used reconstructive techniques.

METHODS

A systematic review and meta-analysis were performed using studies that investigated outcomes after the reconstruction of a partial hypopharyngeal defect. The outcomes of interest were fistulas, strictures, flap failure, swallowing function and postoperative speech.

RESULTS

Of the 4035 studies identified, 23 were included in this review. Four common reconstructive techniques were reported, with a total of 794 patients: (1) pectoralis major myocutaneous and (2) myofascial flap, (3) anterolateral thigh free flap and (4) radial forearm free flap. Fistulas occurred significantly more often than pectoralis major myocutaneous flaps (34%, 95% CI 23-47%) compared with other flaps (p < 0.001). No significant differences in the rates of strictures or flap failure were observed. Pectoralis major myofascial flaps were non-inferior to free-flap reconstructions. Insufficient data were available to assess speech results between flap types.

CONCLUSION

Pectoralis myocutaneous flaps should not be the preferred method of reconstruction for most patients, considering their significantly higher rate of fistulas. In contrast, pectoralis major myofascial flaps yield promising results compared to free-flap reconstructions, warranting further investigation.

Pedicled flaps reconstruction of hypopharynx and laryngeal defects: Successful preservation of laryngeal function in patients with advanced hypopharyngeal cancer

BACKGROUND

Preserving laryngeal function and reconstructing the hypopharynx in advanced hypopharyngeal cancer pose significant challenges for head and neck surgeons.

METHODS

A 48-year-old male patient was diagnosed with advanced hypopharyngeal cancer originating from the left pyriform sinus. The tumor extended into the hypopharynx, left vocal cord, ventricular fold, partial aryepiglottic fold, and a segment of the cervical esophagus. A curative tumor resection was performed, and a well-thought-out strategy was employed for hypopharyngeal repair and laryngeal reconstruction.

RESULTS

Following the surgery, the patient demonstrated exceptional flap survival, and the tracheostomy tube was removed at the 6-month mark. No surgery-related complications were observed, and both swallowing and vocal functions exhibited a robust recovery.

CONCLUSION

Our reconstruction strategy proves effective in preserving laryngeal function among patients with advanced hypopharyngeal cancer.

Dysphagia After Total Laryngectomy: An Exploratory Study and Clinical Phase II Rehabilitation Trial with the Novel Swallowing Exercise Aid (SEA 2.0)

The aims of this exploratory study and clinical phase II trial were to assess the specific nature and extent of dysphagia in laryngectomized patients with self-reported dysphagia, and its rehabilitation potential using the novel Swallowing Exercise Aid (SEA 2.0). Twenty laryngectomized patients participated in a six-week exercise program with the SEA 2.0. Exercises consisted of Chin Tuck Against Resistance (CTAR), Jaw Opening Against Resistance (JOAR), and Effortful Swallow Against Resistance, conducted three times per day. Swallowing was assessed at baseline (T0), six (T1) and 14 (T2) weeks, consisting of patient-reported outcomes, BMI, videofluoroscopy, swallowing capacity, and muscle strength measurements. Dysphagia significantly impacts quality of life, with impaired swallowing speed and bolus propulsion as main reported issues. Subjective dysphagia parameters, swallowing capacity, and pharyngeal residue clearance were reduced, but BMI was normal. Muscle and tongue strength were within normal ranges. All participants managed to use the SEA 2.0. Adherence was 95%. At T1, subjective swallowing parameters (MDADI and EAT-10) showed clinically relevant improvements. Objectively, CTAR and JOAR strength increased with 27.4 and 20.1 Newton, respectively. Also, swallowing capacity (from 2.4 g/s to 3.8 g/s) and pharyngeal residue clearance improved. At T2, results were slightly lower than at T1, but still better than at baseline. Dysphagia in laryngectomized patients affects quality of life, but swallowing can be improved with a six-week rehabilitation program using the novel SEA 2.0. Adherence was excellent and several subjective and objective swallowing parameters improved.

Outcome Comparison of Functional Laryngectomy for the Dysfunctional Larynx to Salvage Laryngectomy

OBJECTIVE

To compare functional outcomes of total laryngectomy (TL) with microvascular free tissue transfer (MVFTT) reconstruction in the treatment of dysfunctional larynx (DL) versus salvage therapy for locally recurrent disease in patients with a history of laryngeal squamous cell carcinoma (SCC).

METHODS

Retrospective review from a tertiary medical center between August 2015 and August 2022.

RESULTS

Sixty-nine patients underwent TL with MVFTT following primary laryngeal radiation or chemoradiation; 15 (22%) patients underwent functional laryngectomy (FL) and 54 (78%) underwent a salvage laryngectomy (SL). There were no total flap failures. Four (6%) patients developed a pharyngocutaneous fistula; one (7%) FL patient and 3 (6%) in the SL cohort. There was no significant difference in average hospital length of stay (LOS) between the cohorts (8.6 ± 3.0 days vs. 12.8 ± 10.1 days, p = 0.12). All patients (100%) in the FL cohort achieved a total oral diet compared to 41 (76%) in the SL cohort (p = 0.03). Two (13%) and 10 (19%) patients developed pharyngoesophageal stenosis in the FL and SL cohorts, respectively (p = 1.0). Nine (60%) and 23 (43%) patients in the FL and SL cohorts underwent tracheoesophageal puncture (TEP) placement, with 89% and 91% achieving fluency, respectively (p = 0.23).

CONCLUSION

Although the role of TL for the definitive treatment of laryngeal SCC has decreased over the past 30 years, organ-preservation protocols can impact speech, swallowing, and airway protection with life-threatening consequences. The use of elective FL with MVFTT for the treatment of DL results in similar or better functional outcomes compared to SL for recurrent disease.

Larynx Cancer: Reconstructive Options

Reconstruction for laryngeal cancer will depend on the defect left by surgical resection and patient-related factors such as medical comorbidities and history of previous radiation treatment. The goals of reconstruction are to preserve and/or restore the primary functions of the larynx (breathing, swallowing, voicing). Options include primary closure, locoregional flaps, and microvascular free tissue each with their advantages and disadvantages, which should be considered when planning reconstruction.

Management of Locally Advanced Laryngeal Cancer-From Risk Factors to Treatment, the Experience of a Tertiary Hospital from Eastern Europe

Laryngeal cancer is an important oncological entity in which prognosis depends on the establishment of appropriate preventive and diagnostic measures, especially in high-risk populations. We present a retrospective two-year study (January 2021 to December 2022) with 152 patients diagnosed with laryngeal cancer from a tertiary hospital in Romania. The average age of the patients was 62 years old for both sexes, with a range from 44 to 83 years. The most frequent symptom was dysphonia with or without dyspnea in 142 cases (93.42%), followed by dyspnea alone in nine patients (5.92%) and dysphagia in one case (0.66%). Surgical treatment in this study consisted of partial laryngectomy (CO₂ laser transoral tumor ablation, supraglottic horizontal laryngectomy or hemilaryngectomy), or total laryngectomy. The main treatment was total laryngectomy (63%). For the eight patients with initial organ preservation treatment, the average time of recurrence was about two-and-a-half years. For the four patients who underwent a total circular pharyngo-laryngectomy, the upper digestive tract needed to be rebuilt with a salivary bypass tube or with a tubed myocutaneous flap from the major pectoralis muscle. One strong point is characteristic of the study group in gathering patients with advanced stages of laryngeal carcinoma candidates for salvage surgery and extended reconstruction methods. The development of new prevention protocols is mandatory in Eastern European countries.

Neopharyngeal Stricture following Laryngectomy

Stricture formation is a serious complication following pharyngeal reconstruction. These strictures can be life-threatening and can severely impact quality of life. In this article, the existing literature on surgical risk factors linked to neopharyngeal stricture formation is reviewed. Intraoperative preventative measures reconstructive surgeons should consider are also discussed. Finally, this article will describe the evaluation and management of pharyngoesophageal strictures, including the challenges and options when dealing with refractory strictures.

Incidence of Pharyngocutaneous Fistula After Total Laryngectomy and Its Relationship With the Shapes of Mucosa Closure: A Meta-Analysis

Background and objective

Pharyngocutaneous fistula is the most common complication after total laryngectomy. The aim of this study was to examine the incidence of fistula and the association between fistula and the shape of mucosal closure (T-shaped, vertical, or horizontal closure).

Method

A search of English language databases from 1979 to 2021 was undertaken for studies of total laryngectomy that commented on pharyngeal closure techniques and fistulas. Pooled estimates for fistula incidence and odds ratios were calculated.

Results

A total of 24 retrospective studies were included. The pooled fistula rates in primary total laryngectomy were 19.9% with T-shaped closure, 16.1% with vertical closure, and 16.4% with horizontal closure. In salvage total laryngectomy, the pooled fistula rates were 35.1%, 36.1%, and 17.9% with T-shaped, vertical, and horizontal closure, respectively. In the analysis of association, the risk of fistula formation in the T-shaped closure was not significantly different compared to that in the vertical closure, (odds ratio, 0.96; 95% confidence interval, 0.46-2.00). The horizontal closure, when compared to vertical closure, was significantly associated with lower risk of fistula formation (odds ratio, 0.31; 95% confidence interval, 0.12-0.78), but had nonsignificant lower risk of fistula formation when compared to the T-shaped closure (odds ratio, 0.46; 95% confidence interval, 0.19-1.12).

Conclusion

Horizontal closure seems to be the best closure shape for primary repair after total laryngectomy. However, analysis bias may have occurred because of the lack of well-controlled studies.

Free Flap microvascular pharyngeal closure results in improved dysphagia-specific quality of life following total laryngectomy

Background

Total laryngectomy (TL) as either a primary or salvage treatment strategy remains an effective oncologic operation in the management of laryngeal cancer. Dysphagia is the most common complication following TL and this has a significant impact on patients’ quality of life (QOL). Following removal of the larynx, a number of pharyngeal closure techniques exist. We aimed to evaluate the effect pharyngeal closure techniques have on dysphagia-specific QOL postoperatively.

Methods

We retrospectively reviewed patients who had undergone TL at our institution (2014–2019). Patients alive at the time of study were invited to complete the MD Anderson Dysphagia Inventory (MDADI). Outcomes were compared among Primary Closure (PC), Pedicled Pectoralis Major Myocutaneous Flap (PMMF) and Free Flap (FF) closure groups.

Results

There were 27 patients identified for inclusion. Eight patients (30%) underwent PC, 10 patients (37%) had PMMF-assisted closure and 9 patients (33%) underwent FF-assisted closure. Patients within the FF group scored consistently higher MDADI scores across all subscales (emotional, functional, physical, global) as well as composite MDADI score in comparison to the PC and PMMF groups. FF closure was associated with a reduced inpatient length of stay (LOS). Additionally, no significant differences in postoperative morbidity including rates of pharyngo-cutaneous fistula (PCF) were observed between groups.

Conclusions

We now advocate FF closure for our patients following salvage TL due to the improved dysphagia-specific QOL, reduced inpatient LOS and lack of additional surgical morbidity.

Total Laryngectomy: A Review of Surgical Techniques

Since the first total laryngectomy was performed in the late 18th century, several improvements and variations in surgical techniques have been proposed for this procedure. The surgical techniques employed in total laryngectomy have not been comprehensively discussed to date. Thus, the main objective of this article was to address controversial aspects related to this procedure and compare different surgical techniques used for a total laryngectomy procedure from the beginning to the end.

Although the management paradigms in laryngeal and hypopharyngeal squamous cell carcinomas have shifted to organ-preserving chemoradiotherapy protocols, total laryngectomy still plays a prominent role in the treatment of advanced and recurrent tumors. The increased incidence of complications associated with salvage total laryngectomy has driven efforts to improve the surgical techniques in various aspects of the operation. Loss of voice and impaired swallowing are the most difficult challenges to be overcome in laryngectomies, and the introduction of tracheoesophageal voice prostheses has made an enormous difference in postoperative rehabilitation and quality of life. Advancements in reconstruction techniques, tumor control, and metastatic management, such as prophylactic neck treatments and paratracheal nodal dissection (PTND), as well as the use of thyroid gland-preserving total laryngectomy in selected patients have all led to the increasing success of modern total laryngectomy. Several conclusions regarding the benchmarking of surgical techniques cannot be drawn. Issues regarding total laryngectomy are still open for discussion, and the technique will continue to require improvement in the near future.
