RESUMO

Importance: Oncocytic (Hürthle cell) thyroid carcinoma is a follicular cell-derived neoplasm that accounts for approximately 5% of all thyroid cancers. Until recently, it was categorized as a follicular thyroid carcinoma, and its management was standardized with that of other differentiated thyroid carcinomas. In 2022, given an improved understanding of the unique molecular profile and clinical behavior of oncocytic thyroid carcinoma, the World Health Organization reclassified oncocytic thyroid carcinoma as distinct from follicular thyroid carcinoma. The International Thyroid Oncology Group and the American Head and Neck Society then collaborated to review the existing evidence on oncocytic thyroid carcinoma, from diagnosis through clinical management and follow-up surveillance. Observations: Given that oncocytic thyroid carcinoma was previously classified as a subtype of follicular thyroid carcinoma, it was clinically studied in that context. However, due to its low prevalence and previous classification schema, there are few studies that have specifically evaluated oncocytic thyroid carcinoma. Recent data indicate that oncocytic thyroid carcinoma is a distinct class of malignant thyroid tumor with a group of distinct genetic alterations and clinicopathologic features. Oncocytic thyroid carcinoma displays higher rates of somatic gene variants and genomic chromosomal loss of heterozygosity than do other thyroid cancers, and it harbors unique mitochondrial DNA variations. Clinically, oncocytic thyroid carcinoma is more likely to have locoregional (lymph node) metastases than is follicular thyroid carcinoma-with which it was formerly classified-and it develops distant metastases more frequently than papillary thyroid carcinoma. In addition, oncocytic thyroid carcinoma rarely absorbs radioiodine. Conclusions and Relevance: The findings of this review suggest that the distinct clinical presentation of oncocytic thyroid carcinoma, including its metastatic behavior and its reduced avidity to radioiodine therapy, warrants a tailored disease management approach. The reclassification of oncocytic thyroid carcinoma by the World Health Organization is an important milestone toward developing a specific and comprehensive clinical management for oncocytic thyroid carcinoma that considers its distinct characteristics.

RESUMO

Importance: Identification and preservation of parathyroid glands (PGs) remain challenging despite advances in surgical techniques. Considerable morbidity and even mortality result from hypoparathyroidism caused by devascularization or inadvertent removal of PGs. Emerging imaging technologies hold promise to improve identification and preservation of PGs during thyroid surgery. Observation: This narrative review (1) comprehensively reviews PG identification and vascular assessment using near-infrared autofluorescence (NIRAF)-both label free and in combination with indocyanine green-based on a comprehensive literature review and (2) offers a manual for possible implementation these emerging technologies in thyroid surgery. Conclusions and Relevance: Emerging technologies hold promise to improve PG identification and preservation during thyroidectomy. Future research should address variables affecting the degree of fluorescence in NIRAF, standardization of signal quantification, definitions and standardization of parameters of indocyanine green injection that correlate with postoperative PG function, the financial effect of these emerging technologies on near-term and longer-term costs, the adoption learning curve and effect on surgical training, and long-term outcomes of key quality metrics in adequately powered randomized clinical trials evaluating PG preservation.

RESUMO

Importance: Surgical site infections (SSIs) after vascularized reconstruction of the upper aerodigestive tract (UADT) are associated with considerable morbidity. The association between perioperative prophylaxis practices, particularly topical antisepsis, and SSIs remains uncertain. Objective: To assess the association between perioperative topical antisepsis and SSIs in patients undergoing vascularized reconstruction of the UADT. Design, Setting, and Participants: This cohort study included patients from 12 academic tertiary care centers over an 11-month period, from July 1, 2020, to June 1, 2021. Patients undergoing open surgical procedures requiring a communication between the UADT and cervical skin with a planned regional pedicled flap, free flap, or both were included. Patients with an active infection at the time of surgical procedure were excluded. Main Outcomes and Measures: The primary outcome measure was an SSI within 30 days of surgery. The association of demographic characteristics, perioperative antibiotic prophylaxis, surgical technique, and postoperative care with SSIs was assessed using univariable and multivariable analyses. The relative risk ratio and 95% CIs for developing SSI were calculated for each of the variables based on predetermined categories. Variables for which the relative risk 95% CI did not include the value of zero effect (relative risk = 1.00) were included in the multivariable model. Results: A total of 554 patients (median age, 64 years; range, 21-95 years; 367 men [66.2%]) were included. Cancer ablation was the most frequent reason for surgery (n = 480 [86.6%]). Overall, the SSI rate was 20.9% (n = 116), with most infections involving the head and neck surgical site only (91 [78.4%]). The median time to SSI diagnosis was 11 days (range, 1-28 days). Topical antisepsis mucosal preparation was performed preoperatively in 35.2% (195) and postoperatively in 52.2% (289) of cases. Ampicillin and sulbactam was the most common systemic antibiotic prophylaxis agent used (n = 367 [66.2%]), with 24 hours being the most common duration (n = 363 [65.5%]). On multivariable analysis, preoperative topical antisepsis mucosal preparation (odds ratio [OR], 0.49; 95% CI, 0.30-0.77) and systemic prophylaxis with piperacillin and tazobactam (OR, 0.42; 95% CI, 0.21-0.84) were associated with a decreased risk of a postoperative SSI. The use of an osseous vascularized flap was associated with an increased risk of postoperative SSI (OR, 1.76; 95% CI, 1.13-2.75). Conclusions and Relevance: Findings of this study suggest that preoperative topical antisepsis mucosal preparation was independently associated with a decreased risk of SSIs in a 12-center multi-institutional cohort. Further investigation of the association between individual perioperative practices and the incidence of postoperative SSIs is necessary to develop evidence-based protocols to reduce SSIs after UADT reconstruction.

RESUMO

PURPOSE: Virtual surgical planning (VSP), with custom made implants and guides represents a recent major advance. Nonetheless, knowledge related to practice patterns is limited. The purpose of this study was to provide data from the AHNS Reconstruction Section related to practice patterns, perceived value of VSP, as well as elucidate specific situations which represent high value for the application of VSP. MATERIALS AND METHODS: A multi-center web-based survey consisting of 30 questions regarding practice patterns related to VSP practices delivered via email to 203 members of the AHNS Reconstructive Surgery Section at institutions across North America. RESULTS: There was a 34% response rate (70/203). A majority of the respondents (96%) used VSP in approximately 50% of their mandibular reconstruction cases, and in 42% of maxillary cases. 46% reported using patient specific implants >75% of cases. Respondents estimated that ~17% of patients received dental implant reconstruction. The majority of respondents (71.0%) did not know the cost of VSP at their institution. The remaining respondents indicated the average cost was $6680 per case. VSP was felt to be necessary as a teaching tool by 55.9%. CONCLUSIONS: Our results demonstrate that a majority of respondents frequently utilize VSP in their practice for head and neck reconstruction. Complex, multi-unit reconstructions were felt to offer the greatest value when utilizing VSP. Future work should focus on increasing the rates of dental implant reconstruction in this population, optimizing value of VSP with careful case selection, and understanding the educational value and costs of these platforms.

RESUMO

We hypothesized the combination of cetuximab and nivolumab would improve survival in recurrent and/or metastatic (R/M) HNSCC by providing synergy in cancer control and evaluated toxicities and efficacy of the combination. Effects of sequential administration of cetuximab and anti-Programmed Cell Death-1 checkpoint inhibitors (CPI) were also explored. Patients who failed at least one line of palliative treatment for incurable HNSCC were treated with cetuximab 500 mg/m2 IV on Day (D)-14 as a lead-in followed by cetuximab 500 mg/m2 IV and nivolumab 240 mg/m2 IV on D1 and D15 every 28-D cycle. Electronic health record-derived real-world data (RWD) were used to explore sequential treatment effects of CPI and cetuximab. A total of 45 evaluable patients were analyzed, and 31/45 (69%) patients had prior exposure to either CPI or cetuximab. The only grade 4 treatment-related adverse event was cetuximab infusion reaction in one patient. The 1-year progression-free survival (PFS) and overall survival (OS) rates were 19% and 44%, respectively. Although patients with no prior CPI (23/45, 51%) showed a trend for more favorable PFS relative to patients with prior CPI (22/45, 49%), the improvement in the 1-year OS did not reach the statistical threshold. For evaluation of sequential CPI and cetuximab treatment effects, we selected RWD-cetuximab cohort with 173 patients and RWD-CPI cohort with 658 patients from 6862 R/M HNSCC. Our result suggested patients treated with RWD-cetuximab after RWD-CPI had worse OS compared to no prior RWD-CPI (HR 1.81, 95% CI 1.02-3.16). Our data suggest the combination of cetuximab and nivolumab is well tolerated. Optimal sequencing of cetuximab and CPI may have an impact in prognosis and requires further evaluation.

RESUMO

Systemic therapy for patients with head and neck cutaneous squamous cell carcinoma (HNCSCC) generally is used for patients with advanced disease and most often employed for patients in the palliative setting when disease is unresectable and/or widely metastatic. Cytotoxic agents and epidermal growth factor receptor pathway targeted therapy have been utilized most commonly, with few clinical data to support their efficacy. Adjuvant postoperative chemoradiation with platinum has been called into question based on recent data. Programmed cell death protein 1 receptor immune checkpoint inhibitors have demonstrated profound activity in HNCSCC, and cemiplimab and pembrolizumab now are approved for use for unresectable/metastatic disease.

RESUMO

Importance: Data regarding outcomes after major head and neck ablation and reconstruction in the growing geriatric population (specifically ≥80 years of age) are limited. Such information would be extremely valuable in preoperative discussions with elderly patients about their surgical risks and expected functional outcomes. Objectives: To identify patient and surgical factors associated with 30-day postoperative complications, 90-day mortality, and 90-day functional decline; to explore whether an association exists between the type of reconstructive procedure and outcome; and to create a preoperative risk stratification system for these outcomes. Design, Setting, and Participants: This retrospective, multi-institutional cohort study included patients 80 years or older undergoing pedicle or free-flap reconstruction after an ablative head and neck surgery from January 1, 2015, to December 31, 2017, at 17 academic centers. Data were analyzed from February 1 through April 20, 2019. Main Outcomes and Measures: Thirty-day serious complication rate, 90-day mortality, and 90-day decline in functional status. Preoperative comorbidity and frailty were assessed using the American Society of Anesthesiologists classification, Adult Comorbidity Evaluation-27 score, and Modified Frailty Index. Multivariable clustered logistic regressions were performed. Conjunctive consolidation was used to create a risk stratification system. Results: Among 376 patients included in the analysis (253 [67.3%] men), 281 (74.7%) underwent free-flap reconstruction. The median age was 83 years (range, 80-98 years). A total of 193 patients (51.3%) had 30-day serious complications, 30 (8.0%) died within 90 days, and 36 of those not dependent at baseline declined to dependent status (11.0%). Type of flap (free vs pedicle, bone vs no bone) was not associated with these outcomes. Variables associated with worse outcomes were age of at least 85 years (odds ratio [OR] for 90-day mortality, 1.19 [95% CI 1.14-1.26]), moderate or severe comorbidities (OR for 30-day complications, 1.80 [95% CI, 1.34-2.41]; OR for 90-day mortality, 3.33 [95% CI, 1.29-8.60]), body mass index (BMI) of less than 25 (OR for 30-day complications, 0.95 [95% CI, 0.91-0.99]), high frailty (OR for 30-day complications, 1.72 [95% CI, 1.10-2.67]), duration of surgery (OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), flap failure (OR for 90-day mortality, 3.56 [95% CI, 1.47-8.62]), additional operations (OR for 30-day complications, 5.40 [95% CI, 3.09-9.43]; OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), and surgery of the maxilla, oral cavity, or oropharynx (OR for 90-day functional decline, 2.51 [95% CI, 1.30-4.85]). Age, BMI, comorbidity, and frailty were consolidated into a novel 3-tier risk classification system. Conclusions and Relevance: Important demographic, clinical, and surgical characteristics were found to be associated with postoperative complications, mortality, and functional decline in patients 80 years or older undergoing major head and neck surgery. Free flap and bony reconstruction were not independently associated with worse outcomes. A novel risk stratification system is presented.

RESUMO

OBJECTIVE: A number of in vitro and clinical studies have suggested potential antineoplastic effects of metformin. The impact of this medication on outcomes in head and neck cancer is less clear. Our aim was to determine the effect of metformin on outcomes within our large cohort of head and neck cancer patients with Type II Diabetes (T2DM). STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary Cancer Centre. SUBJECTS AND METHODS: A retrospective review of individuals with head and neck squamous carcinoma (HNSCC) and T2DM between January 2005 and December 2011 at Princess Margaret Cancer Centre was conducted. Medication history was obtained from surveys at initial presentation and electronic medical record review. Using Cox regression analyses, the association between metformin use and local, regional and distant failures was explored. Subgroup analyses were conducted for oral cavity, oropharynx and larynx. RESULTS: A total of 329 HNSCC patients with T2DM were identified, including 195 metformin users and 134 non-metformin users. Patients were well-matched in terms of clinical, pathologic, and treatment factors. No difference in local, regional, or distant failure was observed between diabetic metformin users and diabetic non-metformin users for the entire cohort or within subgroup analysis for subsite. No difference between the two groups was observed for overall survival, recurrence-free survival, and disease-specific survival at 5 years. CONCLUSION: No association between metformin use and oncologic outcomes were observed in this large cohort of HNSCC patients. Multicenter, prospective studies may be needed to verify previous studies identifying a potential anti-neoplastic effect of this medication.

RESUMO

IMPORTANCE: The historically reported rates of subclinical cervical nodal metastases in oropharyngeal squamous cell carcinoma (OPSCC) predate the emergence of human papillomavirus as the predominant causative agent. The rate of occult nodal disease with changing etiology of OPSCC is not known, and it is challenging to anticipate which patients will be upstaged postoperatively and will require adjuvant therapy. OBJECTIVE: To assess the rate of nodal upstaging and occult extranodal extension (ENE) in a multi-institutional population of patients with pathologic (p)T1-2 OPSCC treated by transoral robotic surgery and neck dissection. DESIGN, SETTING AND PARTICIPANTS: This retrospective, multicenter cohort study of 92 participants at 2 US institutions (Albert Einstein College of Medicine, Bronx, New York [n = 38], and Icahn School of Medicine at Mount Sinai, New York, New York [n = 39]) and 1 Canadian institution (Princess Margaret Hospital, Toronto [n = 15]) examined the rate of postoperative pathologic upstaging for 92 patients with pT1-2 OPSCC undergoing transoral robotic surgery with neck dissection from August 2007 to December 2016. A neuroradiologist at each site blinded to final pathologic diagnosis reviewed preoperative imaging; these findings were compared with operative pathology and applied for tumor staging using the eighth edition of the American Joint Committee on Cancer Cancer Staging Manual. The statistical analysis was performed on December 18, 2018. MAIN OUTCOMES AND MEASURES: Occult pathologic nodal disease and change in nodal category postoperatively. RESULTS: Of 92 patients who met the inclusion criteria, 76 (83%) were male, and they had a mean (SD) age at surgery of 59.5 (10.5) years; 70 patients (84%) with available p16 status were positive. Five of 18 patients (28%) who had no evidence of nodal disease on imaging had occult pathologic nodal disease. Seven of 32 patients (22%) presenting with no nodal disease or with a single metastatic node on imaging received pathologic upstaging because of multiple positive nodes, indicating implementation of additional adjuvant treatment not anticipated after a priori imaging. Changes included 12 patients (13%) who had pathologic nodal upstaging and 12 (13%) with pathologic nodal downstaging in the eighth edition of staging. In the cohort, 24 patients (27%) had pathologic ENE, and 5 of 39 patients (13%) had occult ENE in the absence of radiographic evidence. CONCLUSIONS AND RELEVANCE: Predicting pathologic staging preoperatively for patients with OPSCC undergoing transoral robotic surgery and neck dissection remains a challenge. Although nodal size, tumor size, and location do not help predict ENE, the presence of nodes on imaging and nodal category may help predict ENE. Our findings suggest a small proportion of patients might benefit from further adjuvant therapies not predicted by preoperative imaging based on occult nodal upstaging and ENE.

RESUMO

BACKGROUND: Knowledge of the rate of occult contralateral nodal disease for oropharynx cancers (OPSCC) in the era of Human Papillomavirus-dominated disease would inform practitioners as to who may be a candidate for unilateral neck management. The objective of this study was to determine the rate of pathologic contralateral positive nodes in patients in OPSCC patients with pT1 and pT2 disease treated with TORS and bilateral neck dissections (BND). METHODS: Retrospective review of medical records was performed at Princess Margaret Cancer Center, Toronto; Icahn School of Medicine at Mount Sinai, New York City; and Montefiore Medical Center, New York City. Patients with pT1-2 N0-3 (AJCC 8th Edition) OPSCC disease treated with TORS and BND were included. RESULTS: Thirty-two patients met inclusion criteria. Twelve patients (37.5%) had a tonsil primary site, 19 (59.4%) patients had a base of tongue primary site, and 1 (3.1%) patient had a pharyngeal wall primary. Twenty-four (75%) patients were known to be p16+. Twenty-seven patients (84.4%) were radiographically negative in the contralateral neck preoperatively, and two of these patients had pathologic contralateral positive nodes. The occult pathologic contralateral nodal metastasis rate was 7.4% (2/27). The sensitivity, specificity, positive predictive value, and negative predictive value of suspicious contralateral nodes on preoperative imaging for pathologically positive nodes were 33.3%, 86.2%, 20% and 93% respectively. In the p16+ subgroup, the occult nodal positive rate in the contralateral neck was 5%. CONCLUSIONS: pT1-2 OPSCC patients undergoing TORS and elective contralateral neck dissection have a low rate of pathologic contralateral nodal positivity.

RESUMO

Importance: The most common cause of oropharyngeal squamous cell carcinoma is human papillomavirus (HPV) infection, and currently the standard of care to determine the HPV infection status in this type of carcinoma is to use p16 immunohistochemistry as a surrogate marker of high-risk HPV infection. Although p16 immunohistochemistry is limited by the inability to determine the specific HPV genotypes, oral gargle samples may be a readily available source of HPV DNA for genotyping. Objective: To determine the specific HPV genotypes present in both oral gargle samples and tumor specimens. Design, Setting, and Participants: This prospective, biomarker cohort study conducted at a single specialized cancer hospital in Florida screened approximately 800 potentially eligible participants from May 2014 through October 2017. To be eligible for participation, patients had to meet all of the following criteria: 18 years of age or older, male sex, newly diagnosed as having stage I to IV cancer of the oropharynx, a squamous cell carcinoma diagnosis, treatment naive or at least 4 weeks after chemoradiation or surgical treatment of other diseases, fully understand the study procedures and risks involved, and voluntarily agree to participate by signing an informed consent statement. Main Outcomes and Measures: Detection rate of HPV infection and HPV genotypes in oral gargle samples and tumor specimens. Results: A cohort of 204 male participants with newly diagnosed oropharyngeal squamous cell carcinoma was assessed in this prospective collection of comprehensive clinical data and oral gargle samples. Most study participants (190 [93.1%]) were white and ever smokers (114, 55.9%), with a median age of 61 years (range, 35-87 years). The HPV infection status could be assessed in 203 of 204 participants (99.5%) using oral gargle samples: 35 samples (17.2%) were negative for HPV infection, whereas 168 samples (82.8%) were positive for HPV infection. The detection rate of HPV genotypes was 93.0% in tumor specimens (160 specimens) and 82.8% (168 samples) in oral gargle samples. The oral gargle samples frequently had low-risk HPV genotypes that were not detected in tumors, but these low-risk genotypes were always a coinfection with high-risk genotypes. Conclusions and Relevance: Oral gargle samples can be used to detect the majority of clinically relevant HPV genotypes found in oropharyngeal squamous cell carcinoma, but the interpretation of HPV detected in these samples should be assessed with caution for general cancer risk assessment given that sensitive assays can concomitantly detect low-risk genotypes.

RESUMO

OBJECTIVE: Extracapsular dissection (ECD) has become an accepted, less invasive alternative for the removal of select benign parotid lesions that may reduce complications. Minimal margin extracapsular dissection (MECD) with dissection on or closer to the tumor capsule may be a reasonable alternative to ECD. The objective of this study is to review the complications and safety of the MECD technique at a single institution. SUBJECTS AND METHODS: Medical records for patients who underwent MECD for suspected benign parotid lesions were reviewed. Outcome measurements included intraoperative findings, complications, and recurrences. RESULTS: Forty patients underwent a MECD for suspected benign parotid lesions. The average tumor size was 2.2 cm. Frozen section revealed low-intermediate grade mucoepidermoid carcinoma in 2 (5%) cases, requiring completion of a superficial parotidectomy at the same setting. There was 1 case of temporary facial nerve weakness and no cases of Frey syndrome. No tumor recurrences were observed within the follow-up period (average 3.5 years.) CONCLUSION: In the hands of an experienced surgeon, MECD may be a viable alternative to formal superficial parotidectomy. This study reports low rates of nerve weakness and Frey syndrome. Long-term follow-up is necessary to determine the ultimate risk of recurrence.

RESUMO

BACKGROUND: Orbital decompression is frequently performed in the management of patients with sight-threatening and disfiguring Graves' ophthalmopathy. The quantitative measurements of the change in orbital volume after orbital decompression procedures are not definitively known. Furthermore, the quantitative effect of septal deviation on volume change has not been previously analyzed. OBJECTIVES: To provide quantitative measurement of orbital volume change after medial and inferior endoscopic decompression and describe a straightforward method of measuring this change using open-source technologies. A secondary objective was to assess the effect of septal deviation on orbital volume change. METHODS: A retrospective review was performed on all patients undergoing medial and inferior endoscopic orbital decompression for Graves' ophthalmopathy at a tertiary care academic medical center. Pre-operative and post-operative orbital volumes were calculated from computed tomography (CT) data using a semi-automated segmenting technique and Osirix™, an open-source DICOM reader. Data were collected for pre-operative and post-operative orbital volumes, degree of septal deviation, time to follow-up scan, and individual patient Hertel scores. RESULTS: Nine patients (12 orbits) were imaged before and after decompression. Mean pre-operative orbital volume was 26.99 cm(3) (SD=2.86 cm(3)). Mean post-operative volume was 33.07 cm(3) (SD=3.96 cm(3)). The mean change in volume was 6.08 cm(3) (SD=2.31 cm(3)). The mean change in Hertel score was 4.83 (SD=0.75). Regression analysis of change in volume versus follow-up time to imaging indicates that follow-up time to imaging has little effect on change in volume (R=-0.2), and overall mean maximal septal deviation toward the operative side was -0.5mm. Negative values were attributed to deviation away form the operative site. A significant correlation was demonstrated between change in orbital volume and septal deviation distance site (R=0.66), as well as between change in orbital volume and septal deviation angle (R=0.67). Greater volume changes were associated with greater degree of septal deviation away from the surgical site, whereas smaller volume changes were associated with greater degree of septal deviation toward the surgical site. CONCLUSION: A straightforward, semi-automated segmenting technique for measuring change in volume following endoscopic orbital decompression is described. This method proved useful in determining that a mean increase of approximately 6 cm in volume was achieved in this group of patients undergoing medial and inferior orbital decompression. Septal deviation appears to have an effect on the surgical outcome and should be considered during operative planning.

RESUMO

OBJECTIVES: To report a small case series of an unusual ingested foreign body and a new method for removal of tongue base foreign bodies. METHODS: Three patients were identified with wire bristle foreign bodies between 2009 and 2011 at our academic tertiary medical center. Their medical records were reviewed and are described in this report. RESULTS: Each patient presented to our medical center with progressive pain after ingestion of barbecued food. For 2 patients, the metallic bristle foreign body was imbedded within the lingual tonsil. In these 2 cases, radiofrequency plasma ablation (coblation) assisted partial lingual tonsillectomy was performed to identify the foreign body. In a third case, the foreign body presented as a complex deep space neck abscess and an open trans-cervical approach was required. CONCLUSION: While oropharyngeal and esophageal foreign bodies are common, there are only a few case reports describing this particular foreign body. The presentation of an imbedded wire grill brush bristle can be insidious. Persistent pain and foreign body sensation should be taken seriously in patients with a history of barbecue food ingestion. Intraoperatively, wire bristles can be difficult to localize and extract. Radiofrequency plasma assisted lingual tonsillectomy may be helpful for identifying and removing foreign bodies that are imbedded in the tongue base. Grill brushes should undergo stringent safety regulation, as ingested wire bristles are difficult to localize and remove and may cause significant morbidity.

RESUMO

OBJECTIVE: To compare the outcomes of early versus late extubation after primary single-stage anterior laryngotracheoplasty (LTP) using thyroid ala graft performed at our tertiary care academic children's hospital. METHODS: Twenty-five pediatric patients underwent single-stage anterior LTP using thyroid ala grafts between September 2002 and June 2009. Initial trials of extubation were attempted in 15 patients on or prior to postoperative day (POD) 2 and in 10 patients on or after POD 3. The main outcome measures analyzed in this retrospective comparison study were complication rate, length of hospitalization, reintubation during hospitalization, need for additional airway procedures, and overall decannulation rate. RESULTS: The rates of various complications in each group were not statistically significant, with the exception of methadone taper. No patients in the early extubation group and four patients in the late extubation group required methadone taper [p<0.05]. The average length of hospitalization after extubation for the early extubation group was 16.5 days [SD=14.0] and 14.6 days [SD=7.7] for the late extubation group [p>0.05]. Six patients (40%) in the early extubation group and two (20%) in the late extubation group needed reintubation at some point during hospitalization post-LTP [p>0.05]. Ten patients [66.7%] in the early extubation group and eight [80%] in the late extubation group required additional airway procedures post-LTP [p>0.05]. Ultimately, 12 (80%) of the early extubation group and nine (90%) of the late extubation group were successfully decannulated at the time of most recent follow-up [p>0.05]. CONCLUSIONS: The differences in length of hospitalization, need for additional procedures, reintubation during hospitalization and overall decannulation rate between the early and late extubation groups after single-stage anterior LTP with thyroid ala graft were not statistically significant. Methadone taper was the only complication that was statistically significantly higher in the late extubation group.
