Objectives: To examine the association between treatment status and mortality risk among patients with papillary thyroid cancer (PTC). Methods: We identified 3,679 adults with PTC. Thirty-one untreated patients were matched to 155 treated patients. Hazards ratios (HR) and 95% confidence intervals (CIs) were calculated to estimate all-cause and disease-specific mortality. A low-risk subgroup was analyzed for differences in all-cause mortality. Results: The adjusted HRs (95% CIs) for all-cause mortality at 5 and 10 years were 4.2 (1.7-10.3) and 4.1 (1.9-9.4) and for disease- specific mortality were 14.1 (3.4-59.3) and 10.2 (2.9-36.4), respectively, for untreated versus treated patients. The adjusted HRs (95% CIs) for all- cause mortality was 0.7 (0.1-6.4) for low-risk untreated versus matched treated patients. Conclusions: Compared to treated patients, untreated PTC patients were at higher risk of death while low-risk untreated PTC patients had comparable rate of metastasis and no increased risk of all-cause mortality. Level of evidence: 3

Objectives: The hybrid supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCPL-CHEP, that is, open partial horizontal laryngectomies OPHL Type IIa) has been described using a flexible next generation robotic surgical platform for manipulation. We sought to evaluate the feasibility of performing this procedure using endoscopic transoral (EndoT) surgical techniques without robotics. Methods: Preclinical cadaveric study using two human cadavers. Hybrid SCPL-CHEP was performed with a flexible endoscope for visualization and hand-held instruments for manipulation (SILS Hook monopolar and Dissect, HAVAS LaryngoFIT malleable straight jaw instruments, and Stratafix 4-0 spiral knotless barbed suture). Results: EndoT hybrid SCPL-CHEP was successfully performed. The hand-manipulated rigid instruments allowed for transoral incisions and mucosal suturing. We provide the procedural steps of EndoT hybrid techniques. Conclusions: EndoT hybrid SCPL-CHEP was technically feasible in the preclinical cadaveric laboratory setting and appeared comparable to the hybrid SCPL-CHEP via transoral robotic surgery (TORS). Selected handheld instruments and flexible endoscopy appear to facilitate minimally invasive surgery of the larynx. This novel procedure and technique warrant further clinical study for consideration of feasibility, applicability, and patient benefit.
目的:采用柔性的新一代机器人手术平台进行环骨舌骨会厌瓣固定术(SCPL-CHEP，即开放式部分水平喉切除术OPHL Type IIa)的混合肩胛上部分喉切除术。我们试图评估使用内窥镜经口(EndoT)手术技术进行该手术的可行性，而不使用机器人技术。方法:采用两具人体尸体进行临床前尸体研究。混合SCPL-CHEP采用柔性内窥镜和手持式器械(SILS单极钩和解剖器械，HAVAS喉部可弯曲直颌器械，Stratafix 4-0螺旋无结倒刺缝合)进行观察。结果:成功完成了EndoT杂交SCPL-CHEP。手工操作的刚性器械允许经口切口和粘膜缝合。我们提供了EndoT杂交技术的程序步骤。结论:EndoT混合SCPL-CHEP在临床前尸体实验室环境中技术上是可行的，并且通过经口机器人手术(TORS)与混合SCPL-CHEP相当。选择手持器械和灵活的内窥镜似乎促进了喉的微创手术。这种新方法和技术值得进一步的临床研究，以考虑可行性、适用性和患者的利益。

Objectives: Diesel exhaust particles (DEP)s are notorious ambient pollutants composed of a complex mixture of a carbon core and diverse chemical irritants. Several studies have demonstrated significant relationships between DEP exposure and serious nasal inflammatory response in vitro, but available information regarding underlying networks in terms of gene expression changes has not sufficiently explained potential mechanisms of DEP-induced nasal damage, especially in vivo. Methods: In the present study, we identified DEP-induced gene expression profiles under short-term and long-term exposure, and identified signaling pathways based on microarray data for understanding effects of DEP exposure in the mouse nasal cavity. Results: Alteration in gene expression due to DEP exposure provokes an imbalance of the immune system via dysregulated inflammatory markers, predicted to disrupt protective responses against harmful exogenous substances in the body. Several candidate markers were identified after validation using qRT-PCR, including S100A9, CAMP, IL20, and S100A8. Conclusions: Although further mechanistic studies are required for verifying the utility of the potential biomarkers suggested by the present study, our in vivo results may provide meaningful suggestions for understanding the complex cellular signaling pathways involved in DEP-induced nasal damages.

Background: Surgery with hypnosis avoids the use of general anesthesia (GA). It also shortens hospitalization and promotes outpatient surgery. The objective of this study has been to assess the satisfaction of operated patients. No previous study has focused on patient satisfaction in a prospective design. Methods: In this prospective, non-randomized, observational study, all patients operated with hypnosis between 2009 and 2017 in the Ear, Nose, and Throat department of a tertiary care hospital were selected. All patients were asked to fill a questionnaire based on a previously validated questionnaire incremented with complementary questions. Questionnaires were completed immediately after surgery for 31 patients and after 6 months for 20 patients. Global Satisfaction Index (GSI) was self-assessed on a scale ranging from 1 to 10. Patients were asked; whether they felt comfortable during the operation, whether hypnosis helped them, whether the experience matched their expectations, whether they would revisit or recommend it to someone else and whether they considered to have been sufficiently informed before the procedure. The data was analyzed using a linear regression model with P < .05 considered as statistically significant. Results: During the inclusion period, no patient required conversion to GA. A total of 48 questionnaires were evaluated. The median of the GSI was 8/10. GSI significantly correlated with patient comfort (P < 0.0001) and quality of preoperative information (P = .002). The percentage of patients who found hypnosis helpful correlated with the duration of surgery (P = .04). The probability for a patient to consider hypnosis as an experience matching their expectation increased with surgical team experience OR 0.55 (0.3-0.9). Conclusion: This study reveals that patients’ global satisfaction after hypnosis is high. This is significantly related to the quality of preoperative information and to the experience of the surgical team. It also suggests that patients are more likely to benefit from hypnosis if the surgery is longer.

Objectives: Preoperative maxillary sinus imaging findings have been suggested to be associated with complications and outcomes of sinus lift and dental implant procedures; nonetheless the evidence is controversial. The aim of this study was to examine the association between preoperative maxillary sinus imaging findings and outcomes of sinus lift and dental implant procedures in asymptomatic patients. Methods: We included all patients who underwent maxillary sinus lift and dental implant procedures between 2014 and 2017. Maxillary sinus imaging findings were extracted from pre-procedural dental computed tomography scans, and outcomes of the procedures were assessed. Results: A total of 145 procedures were included. No sinonasal symptoms were reported preoperatively. In 46% of cases maxillary sinus imaging was abnormal. The most common imaging finding was peripheral mucosal thickening (38%). Sinus floor cyst/polyp was identified in 13% of the cases, of which 47% occupied more than 50% of the sinus volume. Partial or complete opacification of the maxillary sinus was documented in 3% of cases. The sinus ostium and ostiomeatal complex were obstructed in 7% and 1%, respectively. Mucosal perforation was documented in 22% of cases and was inversely related to mucosal thickening (P = 0.011). Other minor post-operative complications did not correlate with radiological findings. Post-surgical sinusitis was not observed in any of the patients regardless of pre-surgical imaging findings. Conclusions: Incidental maxillary sinus imaging findings such as mucosal swelling, cysts or polyps, regardless of their severity or size, and maxillary ostial obstruction may not need to be addressed prior to sinus augmentation and dental implant procedures in asymptomatic patients. Patients with complete sinus opacification should be referred to an otolaryngologist prior to surgery. Further controlled trials, in larger cohorts, are needed to corroborate our findings.

Objective: Characterize current perspectives in the surgical management of vestibular schwannoma (VS) to guide otolaryngologists in understanding United States practice patterns. Methods: A retrospective analysis of ACS-NSQIP database was performed to abstract all patients from 2008 to 2016 who underwent VS resection using ICD-9/10 codes 225.1 and D33.3, respectively. The specific surgical approach employed was identified via CPT codes 61520, 61526/61596, and 61591, which represent retrosigmoid (RS), translabyrinthine (TL) and middle cranial fossa (MCF) approaches, respectively. Analyzed outcomes include general surgical complications, total length of stay, and reoperation. Results: A total of 1671 VS cases were identified, 1266 (75.7%) were RS, 292 (17.5%) were TL, and 114 (6.8%) were MCF. The annual number of cases increased over the study period from 15 to 375, which is chiefly attributed to increased institutional participation in ACS-NSQIP. Perioperative variables including BMI (P < .001), ASA class (P = .004), ethnicity (P = .008), operative time (P < .001), and reoperation (P < .001) were found to be statistically significant between cohorts. Increased utilization of RS approach was consistent over the entire study period, with significantly more RS performed than either TL or MCF. Finally, a statistically significant difference with respect to general surgical complication rates was not noted between surgical approaches. Conclusions: There is increased employment of RS approach for the operative management of VS, which likely is the result of increased reliance on both stereotactic radiosurgery and observation as alternative treatment strategies.

Objectives: Laryngomalacia is a common cause of stridor in infants and is associated with laryngopharyngeal reflux (LPR). Although pepsin in operative supraglottic lavage specimens is associated with severe laryngomalacia, detection of pepsin in oral secretions has not been demonstrated in an outpatient setting. Methods: Children <2 years old with laryngomalacia diagnosed by flexible laryngoscopy and children without stridor were selected. Oral secretion samples were obtained in clinic from all subjects. Pepsin, IL-1β, and IL-8 enzyme-linked immunosorbent assays were performed to determine presence of LPR. Results: Sixteen laryngomalacia and sixteen controls were enrolled. Pepsin was detected more frequently in oral secretions of patients with laryngomalacia (13/16) than in controls (2/16; P < .001). Four patients with laryngomalacia developed symptoms requiring supraglottoplasty. Presence and level of salivary pepsin was not significantly associated with need for surgical management, nor were the levels or presence of IL-1β or IL-8 significantly associated with presence or level of pepsin, diagnosis of laryngomalacia, or need for operative management. Conclusion: Pepsin in saliva appears to be associated with laryngomalacia, suggesting a role for salivary pepsin as a noninvasive marker of LPR in patients with laryngomalacia. Future studies will determine the utility of this test in laryngomalacia.

Objectives: To compare preoperative temporal bone high-resolution computed tomography (HRCT) readings to intraoperative findings during exploratory tympanotomy for suspected cases of isolated congenital middle ear malformations (CMEMs) and summarize the malformations that can and cannot be diagnosed with HRCT. Methods: A retrospective study was conducted. All cases were confirmed as isolated CMEMs during surgery. Detailed clinical records were reviewed, with a focus on imaging and surgical findings. Results: One hundred and thirty-two patients and 145 ears were reviewed. Ninety cases (62.1%) could be identified as isolated CMEMs and at least one as middle ear anomaly using preoperative HRCT. Fifty-five cases (37.9%) were reported to be completely normal and the patients underwent exploratory tympanotomy to determine the final diagnosis. Stapes fixation, either alone or associated with other ossicular chain anomalies, contributed to 53.1% of the cases. Most cases of aplasia or dysplasia of the ossicular chain, for example, aplasia/dysplasia of the long process of the incus, aplasia of the stapes’ superstructure, and atresia of the oval window were easily identified in preoperative HRCT. However, fixation of the ossicular chain can be elusive in HRCT, and exploratory tympanotomy is needed for a definitive diagnosis. Conclusions: HRCT provides helpful preoperative clinical information in CMEM and may obviate the need for middle ear exploration in some cases. The negative findings (anomalies that are difficult to identify through preoperative HRCT) and the positive findings (anomalies that are relatively easy to identify through preoperative HRCT) were summarized.

Objectives: To understand that yolk sac tumors (YSTs) of the head and neck (H&N) are exceedingly rare and typically carry a poor prognosis. To acknowledge the possibility of increased incidence in patients with Aicardi Syndrome and the ramifications this has on early diagnosis and treatment in this population. Methods: To date, four germ cells tumors of the H&N have been reported in patients with Aicardi Syndrome. This report presents the second known case of a H&N YST in a patient with Aicardi syndrome. In both cases, the patient was initially misdiagnosed given unconvincing radiologic evidence. However, tissue diagnosis and elevated alpha-fetoprotein (AFP) levels were suggestive of a YST. Results: In contrast to the poor prognosis previously described, both patients with Aicardi syndrome had an excellent chemotherapeutic response exhibited by normalization of AFP levels and imaging. Conclusions: Rare germ cell tumors of the H&N, such as YSTs, have now been documented in several patients with Aicardi syndrome, indicating a possible association given the rarity of these tumors in the population. YSTs should be considered in the differential diagnosis of H&N masses in these patients, with emphasis on early tissue diagnosis and treatment.
