Mammary analogue secretory carcinoma: Update on a new diagnosis of salivary gland malignancy

To review the known histopathologic findings and clinical behavior of mammary analogue secretory carcinoma (MASC).

Systematic review of outcomes following observational and operative endoscopic middle ear surgery.

Middle ear surgery increasingly employs endoscopes as an adjunct to or replacement for the operative microscope. We provide a systematic review of endoscope applications in middle ear surgery with an emphasis on outcomes, including the need for conversion to microscope, audiometric findings, length of follow‐up, as well as disease‐specific outcomes.

The EQ-5D: a new tool for studying clinical outcomes in chronic rhinosinusitis.

To describe the role and applicability of the EuroQol 5‐Dimension, 5‐Level (EQ‐5D‐5L) questionnaire for the assessment of general health‐related quality of life in patients with chronic rhinosinusitis.

Incidence and survival patterns of cranial chordoma in the United States

To determine trends in survival patterns for cranial chordoma in the United States.

Otologic outcomes after blast injury: the Boston Marathon experience

Objective Otologic trauma was the most common physical injury sustained after the April 15, 2013, Boston Marathon bombings. The goal of this study is to describe the resultant otologic morbidity and to report on early outcomes. Study Design Multi-institutional prospective cohort study. Methods Children and adults seen for otologic complaints related to the Boston Marathon bombings comprised the study population. Participants completed symptom assessments, quality-of-life questionnaires, and audiograms at initial and 6-month visits. Otologic evaluation and treatment, including tympanoplasty results, were reviewed. Results More than 100 patients from eight medical campuses have been evaluated for blast-related otologic injuries; 94 have enrolled. Only 7% had any otologic symptoms before the blasts. Ninety percent of hospitalized patients sustained tympanic membrane perforation. Proximity to blast (RR = 2.7, p < 0.01) and significant nonotologic injury (RR = 2.7, p < 0.01) were positive predictors of perforation. Spontaneous healing occurred in 38% of patients, and tympanoplasty success was 86%. After oral steroid therapy in eight patients, improvement in hearing at 2 and 4 kHz was seen, although changes did not reach statistical significance. Hearing loss, tinnitus, hyperacusis, and difficulty hearing in noise remain persistent and, in some cases, progressive complaints for patients. Otologic-specific quality of life was impaired in this population. Conclusion Blast-related otologic injuries constitute a major source of ongoing morbidity after the Boston Marathon bombings. Continued follow-up and care of this patient population are warranted.

EQ-5D-derived health utility values in patients undergoing surgery for chronic rhinosinusitis.

Health utility value (HUV) is an index used to measure health‐related quality of life for the valuation and comparison of treatments. The Euroqol 5‐Dimension (EQ‐5D) questionnaire is a widely used method for determining HUV, but it has not been applied for this purpose in patients with chronic rhinosinusitis (CRS) who undergo sinus surgery.

Incidence and survival patterns of sinonasal undifferentiated carcinoma in the United States.

Objective To determine trends in sinonasal undifferentiated carcinoma (SNUC) survival patterns in the United States. Design Retrospective review of national database. Participants All cases of SNUC in the National Cancer Institutes Surveillance Epidemiology and End Results program from 1973 to 2010 were examined. Main Outcome Measures Age-adjusted incidence and survival rates were calculated and stratified by demographic information and treatment modality. Cohort analysis was performed to analyze survival patterns over time. Results A total of 318 SNUC cases were identified. Age-adjusted incidence rate (IR) was 0.02 per 100,000. Incidence was greater in males (IR: 0.03) than females (IR: 0.01; p = 0.03). Overall 5- and 10-year relative survival rate was 34.9% and 31.3%, respectively. Overall median survival was 22.1 months. Median survival following surgery combined with radiation was 41.9 months. Five-year relative survival rate following surgery, radiation, or surgery combined with radiation was 38.7%, 36.0%, and 39.1%, respectively. Median survival from 1973-1986 and 1987-2010 was 14.5 and 23.5 months, respectively. Conclusions This study provides new data regarding survival patterns of SNUC in the United States, confirming survival benefit with surgery and radiation as well as identifying a trend toward improved survival in recent decades.

Long-Term Outcomes in Sinus Surgery: A New Tool for Measuring Health-Related Quality of Life

Objective The 6-question EuroQol 5-Dimension Health Assessment (EQ-5D) is a widely used, simple instrument that monitors general health-related quality of life (HRQoL) in chronic disease. It has not previously been applied to US patients undergoing endoscopic sinus surgery (ESS). Study Design Prospective cohort study. Setting Academic Medical Center. Subjects and Methods The study population consisted of 267 patients with chronic rhinosinusitis (CRS) who completed 2 disease-specific instruments—the Chronic Sinusitis Survey (CSS) and the Sinonasal Outcomes Test-22 (SNOT-22)—and 1 general health-related quality-of-life instrument—the EQ-5D—before and after ESS for CRS. Baseline scores were compared to those collected 3 and 12 months after surgery and to the general US population. Results Surveys were completed at all time points by 186 patients, for a response rate of 69.7%. Patients with CRS, when compared to the US population, reported more problems in the domains of pain/discomfort (73.1% vs 40.8%, P < .01), anxiety/depression (50.5% vs 26.4%, P < .01), and usual activities (30.6% vs 15.0%, P < .01). One year following ESS, there was a significant decrease in patients who reported problems with pain/discomfort (54.3%, P < .001), anxiety/depression (30.6%, P < .001), and usual activities (21.5%, P < .01). After surgery, CRS anxiety/depression scores were no different from those of the US general population. Chronic Sinusitis Survey and SNOT-22 scores demonstrated similar postoperative improvements. Conclusion The EQ-5D assessment provides meaningful general health outcomes data with low patient burden. Application of this instrument demonstrated long-term improvement in the quality of life of patients who undergo sinus surgery.

Epidemiology of otologic diagnoses in United States emergency departments

Otologic complaints may place a significant burden on emergency departments (EDs) in the United States; however, few studies have comprehensively examined this discrete patient population. We aimed to identify utilization of EDs by patients with primary otologic complaints.

Endoscopic Transcanal Retrocochlear Approach to the Internal Auditory Canal with Cochlear Preservation Pilot Cadaveric Study

Contemporary operative approaches to the internal auditory canal (IAC) require the creation of large surgical portals for visualization with associated morbidity, including hearing loss, vestibular dysfunction, facial nerve injury, and skull base defects that increase the risk of cerebrospinal fluid leak. Transcanal approaches to the IAC have been possible only via a transcochlear technique. To preserve cochlear function, we describe a novel endoscopic transcanal infracochlear approach to the IAC in cadaveric temporal bones. Navigation fiducials were secured on fresh cadaveric heads, and real-time computed tomography imaging was used for surgical guidance. With a combination of curved instruments and rigid angled endoscopy, a transcanal hypotympanotomy and subcochlear tunnel were created with superior extension to access the IAC. Postprocedure imaging and temporal bone dissection confirmed access to the IAC without injury to the cochlea or neighboring neurovascular structures.
