Outcomes of Supracricoid Partial Laryngectomy Performed in the United States: A Systematic Review.

The primary objective of this study was to evaluate oncologic outcomes of all published cases of supracricoid partial laryngectomy (SCPL) performed in the United States. The secondary objective was to assess the functional outcomes associated with this procedure. A systematic review of PubMed, SCOPUS, and Embase for all English-language studies pertaining to SCPL performed in the United States was conducted until August 2021. Primary outcomes included disease-specific survival (DSS), overall survival, and local recurrence rate. Secondary outcomes included larynx preservation rate, gastrostromy tube dependency, days to gastrostomy tube removal, decannulation rate, and days to decannulation. A total of six studies were included in the analysis. A total of 113 patients (58.5%) underwent SCPL surgery as a primary treatment method whereas 80 patients (41.5%) underwent SCPL as salvage surgery. The 5-year DSS rates were 87.8% and 100% for primary and salvage procedures, respectively. Approximately 10.3% of patients undergoing a salvage SCPL procedure experienced a local recurrence whereas only 1.85% of primary SCPL procedures resulted in local recurrence. The rates of decannulation following primary and salvage SCPL were 92.7% and 88.1%, respectively. With regard to swallowing, primary and salvage SCPL procedures demonstrated comparably low postoperative gastrostomy tube dependency rates of 3.66% and 4.76%, respectively. SCPL performed in the United States is an effective surgical technique that produces excellent outcomes in qualifying patients, thus validating its viability as an organ-preserving surgical alternative.

Analysis of swallowing and voice-related quality of life in patients after supracricoid partial laryngectomy

ObjectiveThis study evaluated the swallowing and voice function of laryngeal cancer patients after Supracricoid Partial Laryngectomy(SCPL), and its influence on quality of life to provide a reference for the selection of surgical methods for laryngeal cancer patients.MethodsTwenty-one patients who received SCPL between April 2015 and November 2021 were included. Each patient’s swallowing function and quality of life were assessed through fiberoptic endoscopic examination of swallowing (FEES) and the M.D. Anderson Dysphagia Inventory (MDADI). Fundamental, jitter, shimmer, maximum phonation time (MPT), and voice handicap index-10 (VHI-10) were performed to assess voice function and voice-related quality of life.ResultsThe results of the FEES of the 21 patients were as follows: the rates of pharyngeal residue after swallowing solid, semiliquid, and liquid food were 0%, 28.57%, and 38.09%, respectively; the rates of laryngeal infiltration after swallowing solid, semiliquid, and liquid food were 0%, 28.57%, and 4.76%, respectively; and aspiration did not occur in any of the patients. In the evaluation of swallowing quality of life, the mean total MDADI score was 92.6 ± 6.32. The voice function evaluation showed that the mean F0, jitter, shimmer, and MPT values were 156.01 ± 120.87 (HZ), 11.57 ± 6.21 (%), 35.37 ± 14.16 (%) and 7.85 ± 6.08 (s), respectively. The mean total VHI-10 score was 7.14 ± 4.84.ConclusionSCPL provides patients with satisfactory swallowing and voice function. The patients in this study were satisfied with their quality of life in terms of swallowing and voice. SCPL can be used as a surgical method to preserve laryngeal function in patients with laryngeal cancer.

Partial Horizontal Supracricoid Laryngectomy: Which Factors Impact on Post-decannulation Swallowing Outcomes? A Prospective Single-Center Experience.

Early decannulation, performed within the first ten days after supracricoid partial laryngectomy, can result in a more rapid recovery of swallowing function with a semisolid bolus in the short term, about 30days. We selected 20 patients with squamous cell carcinoma of larynx, who underwent supracricoid laryngectomies: 10 cricohyoidopexy (CHP) and 10 cricohyoidoepiglottopexy (CHEP). Staging was pT2 (10 pts), and pT3 (10 pts). Fiberoptic endoscopic evaluation of swallowing was used to assess postoperative swallowing function after a mean of 12 and 22days from surgery. A modified PAS score (penetration-aspiration scale) was assigned for subtotal laryngectomies. Decannulation occurred after 6.7 ± 2.1days. Univariate analysis showed that the type of surgery (CHP or CHEP), pT, resection of one arytenoid, and decannulation time are significantly associated with the 12-day PAS score. The 22-day PAS score is significantly associated with only 3 variables: type of surgery, pT, and resection of one arytenoid. From the data presented, the factors that most delay an effective recovery of swallowing are T3 and the resection of one arytenoid. Early decannulation has been shown statistically to improve PAS score in the short term, but not in the long term.

Analysis of Clinical Treatment of Laryngeal Stenosis After Radiotherapy and Supracricoid Partial Laryngectomy with Cricohyoidoepiglottopexy of Mid-stage and Advanced Laryngeal Cancer.

To investigate the possible causes and treatment methods of laryngeal stenosis after radiotherapy following supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCPL-CHEP). The data of seven patients with laryngeal stenosis after radiotherapy following SCPL-CHEP were analysed retrospectively. All patients were diagnosed with mid-stage or advanced laryngeal carcinoma before surgery, and the pathological type was squamous cell carcinoma. All patients met the requirements for SCPL-CHEP surgery. When laryngeal stenosis was found during the post-surgical follow-up period, patients were immediately given the appropriate treatment according to their conditions. All seven patients had laryngeal stenosis. One patient underwent granulation resection using a laryngoscope, four patients underwent granulation removal + low-temperature plasma ablation using a laryngoscope, and two patients underwent laryngeal dehiscence surgery + laryngotracheal T-tube placement. All patients recovered well after surgery, with patent airways. Laryngeal stenosis in patients with mid- and late-stage laryngeal carcinoma is one of the rare complications of SCPL-CHEP. Second-stage laryngeal dilatation can be selected according to the patient's laryngeal stenosis. Most patients with laryngeal stenosis can be extubated completely.

Successful 10-year outcomes after supracricoid partial laryngectomy for selected glottic squamous cell carcinoma classified as T3N0M0: A STROBE analysis

PurposeTo evaluate long-term oncological outcome for patients with selected glottic squamous cell carcinoma (SCC) classified as T3N0M0 treated by supracricoid partial laryngectomy (SCPL). Materials and methodsAnalysis of an inception cohort of 46 patients with isolated untreated SCC classified as T3N0M0 and minimum 10-year follow-up, consecutively treated by SCPL between 1982 and 2012 in a French university teaching hospital. The main endpoint was 5- and 10-year actuarial survival and local control estimates. Accessory endpoints comprised cause of death, screening for variables decreasing survival and increasing risk of local recurrence, oncologic consequences of local recurrence, and laryngeal preservation rate. ResultsFive- and 10-year actuarial survival was 78.1%, and 53.3%, respectively. The main causes of death were intercurrent disease and metachronous second primary, each in 33.3% of cases. Postoperative mortality (aspiration pneumonia) was 2.1%. There were no significant correlations between survival and any study variables. Five- and 10-year local control was 90.5%. Overall local recurrence varied significantly (P=0.003), from 2.3% with negative margins (R0) to 100% with positive margins (R1) and/or dysplasia. Local recurrence was associated with a significantly (P<0.005) increased risk of nodal failure and distant metastasis, and reduced survival. Overall laryngeal preservation was 89.1%. ConclusionThe present results suggest that SCPL should continue to be taught and that this type of partial laryngeal surgery should be included in the various organ-sparing strategies considered in advanced laryngeal cancer.

Longitudinal Voice Outcomes and Neoglottic Function After Supracricoid Partial Laryngectomy: The Development of a New Scale.

Supracricoid partial laryngectomy (SCPL) is an oncologically sound alternative to total laryngectomy that results in long-term alterations in vocal function. Little is known about long-term improvements in dysphonia and the mechanism of vocal recovery is unclear due to the lack of a standardized rating tool: The Pattern, Degree, and Vibration (PDV) Scale. Data from 24 individuals were compared over 3 post-operative timepoints after SCPL: 3 to 11, 12 to 35, and over 35 months. Voice outcomes were assessed using the Voice Handicap Index (VHI) and the GRBAS scale. Laryngeal exams were deidentified and rated using a novel rating scheme developed using literature review and consensus panel discussions. There were significant improvements in VHI scores, Grade, and Strain over time. There was an increase in the Degree of Closure and a decline in Mucosal Vibration across timepoints. Pattern of Movement (P) was associated with dysphonia Grade. Better Degree of Closure (D) was associated with lower VHI scores and better Grade and Roughness. Mucosal Vibration (V) was associated with reduced Breathiness and Strain but variable Roughness. Age, T-stage, radiation treatment, surgery type, and time to feeding-tube removal were also associated with voicing characteristics. There is evidence of improvement in several voice parameters over time after the first post-operative year. Various subcomponents of the new PDV rating scale were associated with voice outcomes. Its utility for research and clinical practice merits further investigation.

Narrow-field supracricoid partial laryngectomy: Procedure development and initial clinical experiences

ObjectivesTo evaluate the feasibility of narrow-field supracricoid partial laryngectomy with cricohyoidoepiglottopexy (NF-SCPL-CHEP). MethodsBetween 2019 and 2020, five patients with glottic cancers underwent NF-SCPL-CHEP. The mean durations of surgical drains, tracheostomy canula, and nasogastric tube use were evaluated. Length of stay following NF-SCPL-CHEP was compared with that of our open SCPL historical controls. A case summary is provided for the first patients, with detailed information about postoperative management and function. ResultsAll five patients achieved uneventful postoperative recoveries without major complications. The average time for surgical drains, tracheostomy canula, and nasogastric tube use were 2, 15, and 46 days, respectively. The mean overall hospitalization period was 36 days for NF-SCPL-CHEP patients. The mean period of hospitalization based on our early experiences between 1997 and 2005 with classical open SCPL was 72 days. All patients were fully functional and local recurrences or distant metastases were not encountered during a mean observation period of 39 months. ConclusionsNF-SCPL-CHEP with 6 cm cervical access appeared technically feasible and oncologically sound in this initial clinical experience. An extra 2 cm incision, which enabled lateral neck dissection, was not felt to detract from the overall minimally invasive basis of NF-SCPL-CHEP. The clinical results were encouraging with limited complications and predictable postoperative recovery. The length of stay for patients undergoing NF-SCPL was half that of open SCPL historical controls. Less damages to local circulation may associate with the positive influences. Further study with a large patient sample across multiple institutions are needed to carefully evaluate long-term functional and oncological outcomes.

Laryngectomie partielle horizontale supra-cricoïdienne avec reconstruction : Technique, indications et résultats à l’Hôpital Principal de Dakar

OBJECTIVE: To report technique, indications and outcomes of supracricoid partial laryngectomy (SPL) with crico-hyoido-epiglottopexy (CHEP) or crico-hyoidopexy (CHP) for laryngeal cancers at Hôpital Principal de Dakar. MATERIALS AND METHODS: Retrospective study carried out from January 2009 to December 2016 in the ENT department of Hôpital Principal de Dakar including all patients who underwent SPL with reconstruction for laryngeal cancer. RESULTS: Six patients underwent SPL with CHEP or CHP for laryngeal squamous cell carcinoma. The lesions were classified as T1, T2 or T3. Functional outcomes were simple with normal swallowing and satisfactory voice quality. One patient presented with a local recurrence that motivated total salvage laryngectomy. CONCLUSION: SPL with reconstruction is a good alternative in the management of limited laryngeal cancers. It gives good oncological outcomes while preserving laryngeal functions. However, candidates must be selected and the technique rigorous. KEYWORDS: Cancer; Larynx; Partial laryngectomy; crico-hyoïdo-epiglottopexy; crico-hyoïdopexy.

Mucoepidermoid Carcinomas of the Larynx.

Discussions regarding the specific management and outcomes for laryngeal MEC are limited to very small, single-institution case series. To look further into the diagnosis and management of these uncommon non-squamous cell carcinomas of the larynx, we present 3 recent cases of laryngeal MEC treated at our institution. Patients at a tertiary hospital treated for MEC between October 2019 and December 2020 were retrospectively identified. Chart review, imaging analysis, and histologic slide creation were completed for all patients. We identified and treated 2 patients with high-grade supraglottic and 1 patient with intermediate-grade glottic MEC. These patients presented to our clinic with a primary complaint of either gradual, worsening dysphonia, dysphagia, or both. All patients underwent laryngovideostroboscopy as well as panendoscopy with directed submucosal biopsy, which was consistent with MEC. MRI was performed in 2 of the cases further elucidating the extent of submucosal spread. PET-CT was performed in all 3 cases, and none demonstrated evidence of regional or distal metastases. Surgically, high-grade MEC lesions were treated with a total laryngectomy. The intermediate MEC lesion was managed with a supracricoid partial laryngectomy (SCPL). Surgical margins were free of tumor in all cases with no nodal metastases by modified radical neck dissection. Radiation therapy was offered to both high-grade MEC patients and declined by one. Radiation was not recommended to the patient with intermediate-grade MEC as we believed that the risk of additional treatment outweighed the benefit. We believe that MEC of the larynx should be considered in patients with atypical submucosal laryngeal masses. Laryngovideostroboscopy, MRI, and PET imaging may be valuable in determining the extent of the lesions and planning appropriate surgery. Postoperative radiation therapy should be considered a per tumor grade in other more studied sites, as there is no data on efficacy in laryngeal MEC.

Impact of the COVID-19 pandemic on the stage and the type of surgical treatment of laryngeal cancer

PurposeChanges in the entire health care system during COVID-19 epidemic have affected the management of patients with head and neck cancer and posed several clinical challenges for ENT surgeons. Therefore, the present study aimed to investigate the effect of COVID-19 on the stage and the type of surgical treatments used in laryngeal cancer (including total laryngectomy, supracricoid partial laryngectomy (SCPL) and transoral laser microsurgery (TLM)) and also to compare the results of April 2020 to April 2021 with the previous year. Materials and MethodsThis cross-sectional study was performed on all patients with a diagnosis of laryngeal cancer who underwent surgery in the tertiary care center from April 2020 to April 2021 and the year before the pandemic in the same time. Demographic, cancer stage, and treatment data of all patients were recorded and analysis in two groups. ResultsPatients referred at the time of the virus outbreak; 111 were male and 5 were female, and in the group of patients referred before COVID-19, 90 were male and 12 were female. The type of surgical treatment of laryngeal cancer, mean time elapsed from sampling to surgery, stage of disease and mean tumor volume was statistically significant differences in patients before and during the outbreak. ConclusionPatients who referred for diagnosis and treatment at the time of COVID-19 outbreak had more advanced stages of the disease and also the tumor volume was higher in them than patients who had referred before the outbreak. It is necessary to provide new solutions, education and treatment management for patients with laryngeal cancer in such pandemics.

Oncological and Functional Outcomes of Supracricoid Partial Laryngectomy

Objective: The aim of this study is to review the oncological outcomes of T1-T4 glottic or supraglottic tumor patients who underwent supracricoid partial laryngectomy in our clinic. Material and Methods: A total of 43 patients with laryngeal squamous cell carcinoma who underwent supracricoid partial laryngectomy between January 2014 and December 2016 in the Otorhinolaryngology Department of Istinye University Hospital were retrospectively analyzed. Postoperative data of these patients regarding surgical margin, nasogastric feeding tube removal time, decannulation time, postoperative radiotherapy, local regional recurrence, and distant metastases were recorded. Results: Cricohyoidoepiglotopexy was applied to 16 patients by preserving both arytenoids and applied to 7 patients with a single arytenoid; Cricohyoidopexy was applied to 14 patients with both arytenoids preserved, and 6 patients were treated with a single arytenoid. The five-year survival was compared for Cricohyoidopexy/Cricohyoidoepiglotopexy with single arytenoid to double arytenoid preservation and found to be 80%-76% (p=0.56). The mean 5-year survival was 88% in the post-operative radiotherapy group, and 86% in the non- radiotherapy group. The study compared patients with Cricohyoidopexy/Cricohyoidoepiglotopexy with a single arytenoid to those with double arytenoid preservation; the mean decannulation time was 54.23±34.12 to 35.62±27.08 (p=0.05). Postoperative radiotherapy prolonged the decannulation time (51.16±38.5 versus 32.68±20.1; p=0.043). The duration of nasogastric tube placement in the Cricohyoidopexy/Cricohyoidoepiglotopexy with a single arytenoid group was 50.3±14.3 and double arytenoid preservation was 35.17±32.9 (p=0.088). Nasogastric tube removal time was 53.29±50.2 in the post-operative radiotherapy group and was 30.24±16.8 in patients who did not receive post-operative radiotherapy (p=0.040). Conclusion: Supracricoid partial laryngectomy with Cricohyoidoepiglotopexy and Cricohyoidopexy had satisfactory oncological outcomes, and laryngeal function was preserved by rebuilding the neolarynx.

Supracricoid Partial Laryngectomy: Oncological and Functional Outcomes.

Introduction In the present study, we have reviewed the outcomes of patients with supracricoid partial laryngectomy (SCPL) in our institution. Our results show that SCPL is a well-tolerated procedure with generally good functional outcomes for patients with advanced laryngeal cancer. Objective We analyzed the oncological and functional results of a cohort of 35 patients who had undergone SCPL, and we highlighted the complications, identified the overall and disease-free survivals, demonstrating that the reconstructive laryngectomy guarantees the oncological safety and reproducibility of the oncological results, preserving the laryngeal functions and promoting an improvement in the patient's quality of life, favoring communication and interpersonal relationships. Methods Between 2010 and 2018, 35 patients underwent SCPL for primary and recurrent laryngeal squamous cell carcinomas, and they were divided into two subgroups: in 16 cases, the cricohyoidoepiglottopexy according to the Mayer-Piquet technique was performed, while the remaining 19 cases were submitted to the cricohyoidopexy according to the Labayle technique. In addition to evaluating the oncological results of patients undergoing reconstructive laryngectomy, the present study also aimed to evaluate the functionality of the residual larynx and the quality of life. Results The overall and disease-free survivals were of 83% and 76.3% respectively. All patients were able to swallow. The nasogastric tube was removed after a mean period of 21.8 days (range: 14 to 28 days). The mean decannulation time was of 23.4 days after surgery (range: 15 to 36 days). Conclusion The curves for the overall and disease-free survivals show that SCPL can guarantee oncological safety comparable to that of total laryngectomies in diseases in the intermediate stage and in carefully-selected advanced stages.

Reconstruction of Tracheal Defect by Sternocleidomastoid Muscle Flap Covered with Skin Graft: A Case Report

Supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP) involves the removal of the whole thyroid cartilage, both true and false vocal cords, the ventricles, and the paraglottic spaces, sparing the cricoid cartilage, hyoid bone, and at least one functional and mobile cricoarytenoid unit. Reconstruction is performed by suturing of the cricoid cartilage up tightly to the hyoid bone, so trachea-releasing procedures are needed to prevent leakage at anastomosis site. In case of advanced tranglottic cancer invading tracheal tracheal wall, we need to perform additional circumferentrial tracheal wall resection. However, when we perform SCPL, circumferential resection of tracheal wall is limited because SCPL procedure itself needs releasing of tracheal length. We report a case of advanced transglottic cancer involving tracheal wall treated with induction chemotherapy and SCPL including tracheal wall resection with reconstruction of tracheal defect by sternocleidomastoid muscle flap covered with skin graft.

Supracricoid partial laryngectomy with cricohyoidoepiglottopexy for patients with laryngeal cicatricial stenosis: Safety and efficacy.

We assessed the safety and efficacy of supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCL-CHEP) in patients with laryngeal cicatricial stenosis. Sixteen patients receiving SCL-CHEP for severe laryngeal cicatricial stenosis between 2017 and 2018 were reviewed. Decannulation rate and tracheostomy closure time were used to evaluate efficacy. The Voice Handicap Index-10 (VHI-10), Voice-related Quality of Life (V-RQOL) scale and Grade, Roughness, Breathiness, Asthenia, and Strain (GRBAS) scale were used to assess vocal function. Fiberoptic endoscopic evaluation of swallowing (FEES) was performed and the Penetration-Aspiration Scale (PAS), Eating Assessment Tool-10 (EAT-10), and Swallow Quality of Life Questionnaire (SWAL-QOL) were used to assess swallowing function. Thirteen patients (81.25%) were decannulated successfully. The average tracheostomy closure time was 45.15 days. There was no observed postoperative complications or recurrence of stenosis. VHI-10 and V-RQOL scores showed significantly improved V-RQOL (p< 0.05). FEES-PAS, EAT-10, and SWAL-QOL showed no swallowing function damage. SCL-CHEP is effective and safe for patients with severe laryngeal cicatricial stenosis. Accurate pre-procedure evaluation is especially important for patient selection and surgical success.

Role of Neck Dissection in Organ-Preservation for Glottic Squamous Cell Carcinoma.

The surgical approach to the neck in laryngeal cancer depends on the tumor site and stage. Clinical practice guidelines recommend elective neck dissection in ≥ T2 N0 and all supraglottic cancers; however, there is no evidence supporting these recommendations. The objective is to evaluate the results of bilateral elective neck dissection in patients with glottic cancer who underwent supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP). Thirty-five patients diagnosed with ≥ T2 N0 laryngeal squamous cell carcinoma (LSCC) in a single-center retrospective study. Right-sided neck dissections yielded 900 lymph nodes, none of which were positive for metastatic disease. Left-sided neck dissections yielded 949 lymph nodes, one of which was positive for malignancy. Prelaryngeal (Delphian) neck dissection was performed in all patients. Out of 50lymph nodes removed; one was positive for malignancy. Median overall survival was 172months, and the 60-month overall survival was 87.3%. The 60-month disease-specific survival was 97.1%. Bilateral neck dissection and Delphian node dissection showed a low rate of metastasis (2.8%). Radical neck dissection may thus represent overtreatment; however, this surgical procedure could be justified to prevent regional recurrences.

Quality of life after Supracricoid Partial Laryngectomy

Abstract B39: Role of supracricoid partial laryngectomy in the aging era

Abstract Introduction: Supracricoid laryngectomy (SCL) is a conservative surgical technique for the treatment of selected laryngeal carcinomas, currently adopted also in old patients. But in the aging era, elderly patients represent the fastest-growing section of the population. The aim of this study is to compare the oncologic and functional results in elderly and younger patients following SCL. Materials and Methods: We retrospectively reviewed the medical records of 114 patients who underwent SCL between 1994 and 2013. All of the patients underwent surgery at least 5 years before the study was undertaken. We took the cut-off age of elderly patients as 70 years old, and there were 15 elderly patients. We chose another 15 patients with age younger than 60 years who are matched in stage, primary site, and reconstruction methods. Patients older than 70 years were classified to group I, and patients younger than 60 years were classified to group II. In group 1, the mean age was 53.2 years of age (range 46-60), and in group 2 it was 73.3 years of age (range 71-77). Functional evaluation was performed by evaluating the time of decannulation and nasogastric tube removal, final diet, and duration of hospital stay. Patients’ voice quality was assessed perceptually using GRABS scale. Postoperative complications, especially pulmonary complication such as aspiration pneumonia, were also evaluated. Oncologic results were also evaluated in both groups. Results: The total GRABS score of group I was 8.7 and that of group II was 7.3, and there was no significant statistical difference in these two values. The average time of decannulation was slightly longer in group I; however, these values were not significantly different. The average time of nasogastric tube removal and hospitalization time was significantly longer in group I patients. This was due to the longer duration of swallowing exercise. However, all patients could finally intake orally without gastrostomy. The rate of aspiration pneumonia was slightly higher in group I but failed to show statistical difference. All patients underwent surgery as a primary treatment mordality. In group I, one patient underwent adjuvant radiation, and two patients in group II underwent adjuvant radiation. The 5-year overall survival was 66.6%, 5-year disease-specific survival was 72.1%, and the survival rates of the two groups were not significantly different. Conclusion: Age by itself does not have a significant impact on functional and oncologic results following SCPL. Though elderly patients need more time to take oral diet, that is, need longer time of swallowing exercise, they can finally intake oral diet after swallowing training. Meticulous selection of the candidate to SCPL allows the application of this surgical technique with adequate oncologic and functional results.

Effects of different surgical treatment on swallowing function in partial laryngectomy patients

Objective To explore the effects of different surgical treatments on swallowing function in partial laryngectomy patients and to analyze the development trend of swallowing function. Methods From January 2019 to September 2019, this study selected 54 patients first diagnosed as laryngeal carcinoma with partial laryngectomy at a ClassⅢ Grade A hospital as subjects by convenience sampling. There were 25 patients with vertical partial laryngectomy (vertical group) , 12 patients with horizontal supra-glottic partial laryngectomy (horizontal group) and 17 patients with supra-cricoid partial laryngectomy (SCPL group) . This study observed the time of gastric tube extubation of patients, video-fluoroscopic swallowing study (VFSS) 15 days after surgery, score of Modified Penetration Aspiration Scale (MPAS) and scores of Gugging Swallowing Screen (GUSS) 15, 20 and 30 days after surgery, and compared the swallowing function of patients among three groups. Results There were statistical differences in the time of gastric tube extubation, scores of GUSS and VFSS+MPAS 15 days after surgery among three groups (P<0.01) . When taking time as main effect, the Roy maximum root test displayed F=460.693, P<0.001 which showed that time had influence on the score of GUSS; when taking surgery as the main effect, the Roy maximum root test displayed F=218.387, P<0.001 which showed that surgery type had influence on the score of GUSS. There were statistical differences in the development trends of swallowing at different times among three surgery types when time interacted with the surgery type (F=164.033, P<0.001) . Conclusions The vertical partial laryngectomy has the small impact on swallowing function and patients recovery quickly. However, horizontal supra-glottic partial laryngectomy and SCPL have great impact on swallowing function; swallowing function can't be well compensated by sphincter function of remnant larynx in a short time; besides, patients with horizontal supra-glottic partial laryngectomy need a long rehabilitation period.
