In vivo analysis of endocanalicular light pipe transillumination in endoscopic dacryocystorhinostomy: Anatomic considerations and cautions for the transitioning.

PURPOSE: Localization of the lacrimal sac is a critical step during endoscopic dacryocystorhinostomy (endo-DCR). A "light pipe" can be used to transilluminate the lacrimal sac endonasally. We hypothesized that this may misguide the surgeon learning endo-DCR to create an osteotomy mostly posterior to the maxillary line if only the bone overlying the transillumination was to be removed, as the thinner lacrimal bone will transmit light more readily than the thicker maxillary bone of the frontal process of the maxilla that forms the anterior lacrimal sac fossa. METHODS: The charts of 32 patients with primary acquired nasolacrimal duct obstruction in whom a lighted system was used during endo-DCR at Massachusetts Eye and Ear from April 2015 through October 2016 were reviewed. Patients with prior history of lacrimal surgery or trauma directly to the lacrimal sac fossa were excluded. Location of the maximal point of transillumination in relation to the maxillary line was observed and noted intraoperatively. RESULTS: Of a total of 39 endo-DCR surgeries performed, the intraoperative transillumination point was entirely posterior to the maxillary line in 32 instances (82%). CONCLUSIONS: Use of an endocanalicular light pipe preferentially illuminates posterior to the maxillary line endonasally. The anterior lacrimal sac fossa (maxillary line and anterior as visualized endonasally) is rarely transilluminated, likely due to thicker bone in that region. Surgeons learning how to perform endo-DCR using a light pipe should be aware of this phenomenon.

Clinical outcomes following high-dose-rate surface applicator brachytherapy for angiosarcoma of scalp and face.

PURPOSE: Angiosarcoma is a sub-type of soft tissue sarcoma, often presenting as a multifocal or diffuse disease process with poor prognosis. This study presents outcomes of a single institution cohort of patients with angiosarcoma of the scalp and face following treatment with multimodality therapy, including high-dose-rate surface applicator (HDR-SA) brachytherapy, and represents the largest cohort utilizing this therapeutic approach. MATERIAL AND METHODS: Twenty patients with primary or recurrent angiosarcoma of the face or scalp were treated with HDR-SA brachytherapy between 2003-2018, with clinical characteristics and outcomes collected from medical records and used to identify prognostic features. RESULTS: Median follow-up was 45 months. Patients treated with HDR-SA brachytherapy had a 4-year local control rate of 63%, a 4-year progression-free survival (PFS) rate of 20%, and a 4-year overall survival rate of 54%. Disease features associated with worse loco-regional control (LRC) included location on the scalp (vs. face, p = 0.04) and tumor size ≥ 5 cm (p = 0.0099). Outcomes after HDR-SA brachytherapy for salvage therapy vs. HDR-SA brachytherapy as a component of an initial treatment approach were also significantly different, with worse LRC (p = 0.0084) and worse overall survival (OS) (p = 0.0019) in a setting of salvage therapy. CONCLUSIONS: Local control rates following HDR-SA brachytherapy for scalp or face angiosarcoma are moderate and similar to what is described in the literature using a variety of local control treatment modalities. Smaller tumors and those involving the face rather than scalp had better outcomes. PFS rates were poor and there is a pressing need for treatment intensification and novel therapeutic options.

Trimodality therapy for HPV-positive oropharyngeal cancer: A population-based study: Trimodality therapy for HPV+ OPC.

BACKGROUND: Although HPV status is a well-established prognostic factor in oropharyngeal squamous cell carcinoma (OPSCC), approximately 20% of HPV-positive patients die from their disease. We therefore sought to ascertain whether there is a benefit to trimodality therapy with surgery among patients with locally advanced (LA) disease receiving chemoradiation. METHODS: The SEER Head and Neck with HPV Status Database identified adult patients with non-metastatic OPSCC between 2013 and 2014 with known HPV status who received chemoradiation as part of definitive treatment. The primary outcome was cancer-specific mortality (CSM) for locally-advanced (LA) (T3-T4, or N2-N3, per AJCC 7) versus early-stage (ES) (T1-T2 and N0-N1) disease, stratified by HPV status. The secondary outcome was overall survival (OS). RESULTS: Among 2974 patients who met study criteria, 671 patients (22.6%) received upfront surgery (trimodality therapy). In the LA setting, there was a significant reduction in CSM with trimodality therapy compared to chemoradiation alone in HPV-positive (Adjusted Hazard Ratio [AHR] 0.19, 95% Confidence Interval [CI] 0.04-0.80; P = 0.024), but not HPV-negative disease [Pinteraction = 0.04]. There was no benefit to trimodality therapy for ES disease, regardless of HPV status. There was also an improvement in OS with trimodality therapy for HPV-positive LA patients (AHR = 0.28, p = 0.006, 95% CI = 0.11-0.70). In contrast, trimodality therapy was not associated with improved OS for HPV-negative patients regardless of stage. CONCLUSIONS: HPV status may predict for improved outcomes with surgery/trimodality therapy in LA OPSCC. Our findings support prospective investigations to optimize care for the subset of HPV-positive patients who are at greatest risk of cancer death, where trimodality therapy may be appropriate.

What Do Patients Want from Otolaryngologists? A Discrete Choice Experiment.

Objectives Patient preferences are crucial for the delivery of patient-centered care. Discrete choice experiments (DCEs) are an emerging quantitative methodology used for understanding these preferences. In this study, we employed DCE techniques to understand the preferences of patients presenting for an ear, nose, and throat clinic visit. Study Design DCE. Setting Decision science laboratory. Methods A DCE survey of 5 attributes-wait time, physician experience, physician personality, utilization of visit time, and cost/copayment-was constructed with structured qualitative interviews with patients. The DCE was administered to participants from the general population, who chose among hypothetical scenarios that varied across these attributes. A conditional logit model was used to determine relative attribute importance, with a separate logit model for determining subject effects. Results A total of 161 participants were included. Cost/copayment had the greatest impact on decision making (importance, 32.2%), followed by wait time and physician experience (26.5% and 24.7%, respectively). Physician personality mattered least (4.7%), although all attributes were significantly correlated to decision making. Participants preferred doctors who spent more time performing physical examination than listening or explaining. Participants were willing to pay $52 extra to avoid a 4-week delay in appointment time; $87 extra for a physician with 10 years of experience (vs 0 years); and $9 extra for a caring, friendly, and compassionate doctor (vs formal, efficient, and business-like). Conclusion DCEs allow for powerful economic analyses that may help physicians understand patient preferences. Our model showed that cost is an important factor to patients and that patients are willing to pay extra for timely appointments, experience, and thorough physical examination.

Aseptic Meningitis with Craniopharyngioma Resection: Consideration after Endoscopic Surgery.

Objectives While bacterial meningitis is a concerning complication after endoscopic skull base surgery, the diagnosis can be made without consideration for aseptic meningitis. This article aims to (1) present a patient with recurrent craniopharyngioma and multiple postoperative episodes of aseptic meningitis and (2) discuss the diagnosis and management of aseptic meningitis. Design Case report and literature review. Results A 65-year-old female patient with a symptomatic craniopharyngioma underwent transsphenoidal resection. She returned postoperatively with symptoms concerning for cerebrospinal fluid (CSF) leak and bacterial meningitis. Lumbar puncture demonstrated mildly elevated leukocytes with normal glucose levels. Cultures were sterile and she was discharged on antibiotics. She returned 18 days postoperatively with altered mental status and fever. Again, negative CSF cultures suggested aseptic meningitis. Radiological and intraoperative findings were now concerning for widespread cerebrovascular vasospasm due to leaked craniopharyngioma fluids. In the following months, her craniopharyngioma recurred and required multiple surgical resections. Days after her last operation, she returned with mental status changes and a sterile CSF culture. She was diagnosed with recurrent aseptic meningitis and antibiotics were discontinued. The patient experienced near complete resolution of symptoms. Conclusions Consideration of aseptic meningitis following craniopharyngioma resection is critical to avoid unnecessary surgical re-exploration and prolonged courses of antibiotics.

Primary tracheoesophageal puncture with supraclavicular artery island flap after total laryngectomy or laryngopharyngectomy.

The supraclavicular artery island flap (SCAIF) is increasingly employed for laryngectomy reconstruction with excellent success. Although tracheoesophageal puncture (TEP) with intraoperative prosthesis placement is also positively reported, this is not described in patients following SCAIF. We review our experience with primary TEP with prosthesis placement and voice outcomes in patients after SCAIF reconstruction. Seven patients underwent SCAIF with primary TEP after laryngectomy from 2011 to 2013. Five underwent total laryngectomy (TL) and 2 underwent TL with partial pharyngectomy. All patients had 16 French Indwelling Blom-Singer prostheses placed intraoperatively without complications. Six patients achieved tracheoesophageal voice (median time = 1.5 months). Two patients required cricopharyngeal segment Botox injections. One patient remained aphonic. One patient developed prosthesis leakage addressed with prosthesis replacement. Our preliminary data demonstrate that similar to free tissue transfer reconstruction, primary TEP with intraoperative placement of the voice prosthesis at the time of SCAIF reconstruction is safe and effective.

P-glycoprotein is a marker of tissue eosinophilia and radiographic inflammation in chronic rhinosinusitis without nasal polyps.

BACKGROUND: P-glycoprotein (P-gp) is a membrane-bound efflux pump that is upregulated in chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) and participates in epithelial cytokine secretion. Eosinophilic CRS (ECRS) shares a similar cytokine profile with CRSwNP and is associated with significant inflammation and poor surgical outcomes. The goal of this study is to determine if P-gp expression is associated with degree of eosinophilia and severity of radiographic inflammation in patients with CRS without polyps (CRSsNP). METHODS: An institutional review board (IRB)-approved study using sinus tissue in 39 steroid-naive patients with CRS. P-gp expression was calculated using quantitative fluorescent immunohistochemistry (Q-FIHC) to generate an epithelial to background staining ratio. Patients were stratified into low and high epithelial expression groups (<3 and ≥3, respectively). Average eosinophils per high powered field (hpf) and Lund-Mackay scores were calculated and compared with P-gp staining ratios using a 2-tailed Student t test. RESULTS: Among the 39 patients, 7 (17.95%) had high P-gp expression ratios (mean ± SD, 4.86 ± 1.33) while 32 (82.05%) had low expression ratios (1.91 ± 0.45). The number of eosinophils/hpf were significantly greater in the high P-gp expression group as compared to the low expression group (62.38 ± 83.69 vs 5.11 ± 10.12, p = 0.0003). The Lund-Mackay scores were significantly greater in the high P-gp expression group as compared to the low expression group (11.86 ± 2.79 vs 6.84 ± 4.19, p = 0.005). CONCLUSION: P-gp is known to be overexpressed in CRSwNP. This study suggests that among patients with CRSsNP, P-gp is similarly overexpressed in those with high tissue eosinophilia and correlates with severity of radiographic inflammation.
