Retrospective administrative database analysis. The SEER database (Surveillance, Epidemiology, and End Results) was queried for patients diagnosed with T1/T2N0M0 OT-SCC from 1998 to 2011. Data included patient demographics, initial treatment, and survival outcomes. The Kaplan-Meier model and the Cox proportional hazards model were utilized for survival analysis. Out of 7010 T1/T2N0M0 cases, END was performed in 1770 T1 and 950 T2 cases, and the neck was observed in 3278 T1 and 1001 T2 cases. Significantly poorer 5-year disease-specific survival (DSS) rates were noted for the neck observation group when compared with the END group for tumors with moderately differentiated (72.1% vs 86%, P < .0001) and poorly differentiated or undifferentiated (55.6% vs 71.5%, P = .0001) histologic grades....

Sinonasal hemangiopericytomas have been reported mostly through case studies, and optimal treatment is considered surgical excision. Classically, open surgical methods of tumor extirpation have been considered standard of care. With the wider use of endoscopic methods, an updated systematic review in terms of treatment is warranted. Cases were identified using a MEDLINE and PubMed search. Relevant studies were identified, and data was extracted regarding patient demographics, presenting symptoms, tumor characteristics, treatment, and outcomes. A total of 128 cases were collected from 56 articles, consisting of case reports and series. The most common presenting symptoms were epistaxis, nasal obstruction, and facial pain/swelling/pressure. Computed tomography (CT) and X-ray were the most common modes of imaging during diagnosis and operative planning. The tumor often occupied multipl...

These defects have initially led to increased postoperative cerebrospinal fluid (CSF) leaks. The development of the vascularized pedicled nasoseptal flap (PNSF) has successfully reduced postoperative CSF leaks. Mucocele formation, however, has been reported as a complication of this technique. In this study, we analyze the incidence of mucocele formation after repair of SB defects using a PNSF. A retrospective review was performed from December 2008 to December 2011 to identify patients who underwent PNSF reconstruction for large ventral SB defects. Demographic data, defect site, incidence of postoperative CSF leaks, and rate of mucocele formation were collected. Seventy patients undergoing PNSF repair of SB defects were identified. No postoperative mucocele formation was noted at an average radiological follow-up of 11.7 months (range,...

A retrospective cohort study using the U.S. National Cancer Institute's SEER registry was performed to study the demographics and survival for SNAC from 1973 to 2009. Analysis was conducted based on race, gender, and stage. In total, 1270 cases of SNAC were analyzed for demographics and survival. Males accounted for 51.6% of cases, while females accounted for 48.4% of cases, amounting to a male to female ratio of 1.06:1.00. Disease specific survival at 5, 10, 15, and 20 years was 65.2%, 50.9%, 40.9%, and 36.5%, respectively. When analyzed by gender, females had higher survival than males, although this difference was not statistically significant. When analyzed by race, the category of other, which encompasses American Indian, Asian, Hispanic, and...

This study analyzes the demographic, clinicopathologic, incidence, and survival characteristics of sinonasal ENKTL (SN-ENKTL) and extranasal ENKTL (EN-ENKTL) in a comparative fashion. Retrospective analysis. The Surveillance, Epidemiology, and End Results database was queried; 528 cases were available for frequency and incidence analysis, and 473 for survival analysis. Data were examined according to age, gender, race, histology, the presence of systemic (or B) symptoms, treatment, and Ann Arbor stage. Extranasal disease was a poor prognostic factor (hazard ratio [HR] = 1.69, 95% confidence interval [CI] = 1.30-2.19, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .05).

B symptoms were present in 38.41% of the EN-ENKTL group (vs. 22.86%, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .05), and were a poor prognostic factor in this group only (HR = 1.6593, 95% CI = 1.05-2.62, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .05). Radiation therapy demonstrated a survival advantage among both groups, especially in early stage disease. SN-ENKTL carries a significantly better prognosis than EN-ENKTL, which presents at more advanced stages. Radiation therapy was associated with increased survival in both groups, especially in cases of localized disease. 2b.

Characteristics of AciCC are slow growth and a long clinical course. As a rare tumor, population-based studies are limited. We analyzed the incidence and survival for AciCC using a national population-based database. Retrospective analysis. The United States National Cancer Institute&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Surveillance, Epidemiology, and End Results (SEER) registry was utilized to calculate incidence and disease-specific survival trends for AciCC between 1973 and 2009. Patient data were stratified according to age, gender, race, grade, and extent of disease. Incidence trends were studied across the last 30 years and long-term disease-specific survival outcomes were compared across the different demographic parameters. A total of 1,129 cases of AciCC were identified, comprising of 672 (59.52%) females. Incidence trend analysis revealed significant changes in yearly incidence rates from 1973 to 2009 for male gender and white and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;others&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; races. Overall 5-year survival was 97.15%, 10-year survival was 93.81%, and 20-year survival was 89.74%. Significant differences in survival outcomes were noted for extent of disease. Patients exhibiting distant metastasis displayed the worse long-term prognosis at 21.99% 20-year disease-specific survival. Hazard ratios demonstrated a significant increase in mortality in patients with poorly differentiated, undifferentiated, and metastatic disease. Trends in incidence of AciCC are influenced by gender, race and age. Long-term survival of this rare malignant tumor is influenced by gender, grade, race, and extent of disease. Future studies need to be conducted to investigate these dynamic trends related to AciCC.

As such, it is an effective, objective bibliometric that can be used to evaluate academic otolaryngologists for decisions regarding appointment and advancement. In this study, we evaluate the impact of NIH funding on scholarly productivity in otolaryngology. Analysis of bibliometric data of academic otolaryngologists. Funding data for the 20 otolaryngology departments with the largest aggregate total of NIH grants for the fiscal years (FY) 2011 and 2012 was obtained using the National Institutes of Health Research Portfolio Online Reporting Tools Expenditures and Reports (RePORTER) Database. H-indices were calculated using the Scopus online database, and then compared to funding data at both the departmental and individual level. Faculty members in otolaryngology departments who received NIH funding had significantly greater research productivity and impact, as measured by the h-index, than their nonfunded peers. H-indices increased with greater NIH funding levels, and investigators with MD degrees tended to have higher mean NIH funding levels than those with PhDs. While there was no correlation between average h-index and NIH funding totals at the level of departments, there was greater correlation upon examination of NIH funding levels of individual investigators. The h-index has a strong relationship with, and may be predictive of, grant awards of NIH-funded faculty members in otolaryngology departments. This bibliometric may be useful in decisions regarding appointment and advancement of faculty members within academic otolaryngology departments.

This study reviews the published literature related to SNTCS. Clinical presentation, demographics, radiographic diagnosis, pathology, treatment, and management outcomes of this uncommon disease are reported. A systematic review in the published English literature was conducted. A MEDLINE/PubMed search and bibliographic examination of articles pertaining to SNTCS were performed. Each case was analyzed for patient demographics, clinical presentation, tumor location, diagnosis, treatment, and survival outcome. A total of 49 journal articles were included. Individual patient data were reported in 86 cases. The average age of the patients was 54.5 years (range, 0.1 to 85 years), with a strong male predilection (7:1). Average follow-up was found to be 38.9 months (range, 2 to 372 months). The most common treatment method was surgery with radiation therapy, utilized in 59.3% of patients. Out of 71 cases with reported outcome and follow-up, there were 21 cases of recurrence, 8 cases with metastasis, and 6 cases reporting both recurrence and metastasis. Forty-two out of 71 (59.2%) patients survived at the time of follow-up. This study describes the largest pool of SNTCS patients to date. SNTCS is a rare and aggressive malignant skull base tumor with a poor prognosis with frequent recurrence and metastasis. Although a variety of treatment paradigms have been reported in the literature, radical surgical resection followed by radiation therapy appears to be the most commonly used treatment option.

It is the most common sarcoma in children. In this study, we analyze the incidence and long-term survival for SNRMS using a national population-based database. The United States National Cancer Institute&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Surveillance, Epidemiology, and End Results (SEER) registry was utilized to calculate incidence and survival trends for SNRMS between 1973 and 2009. In addition, data were grouped by age, gender, race, and histopathological subtype. A total of 181 cases of SNRMS were analyzed for incidence trends, showing a 1.23:1 female to male ratio. While the overall incidence of SNRMS increased by 1.02% annually over the last 20years, this pattern was not equal amongst gender and racial groups. The incidence in males has increased, while in females incidence has decreased. An increase in incidence was noted in white and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;others,&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; but decreased in blacks. Using a total of 314 cases for survival analysis, we found that the rate in the white population has been consistently highest with a 5-year survival of 49.45%, 10- and 20-year survival of 48.81%. Survival rates in cases of embryonal SNRMS were also consistently higher than in cases of alveolar SNRMS. Overall incidence of SNRMS is increasing. Histologic subtype and race are important considerations in the long-term prognosis of SNRMS. Future studies will further elucidate gender and race related trends.

Sinonasal hemangiopericytomas have been reported mostly through case studies, and optimal treatment is considered surgical excision. Classically, open surgical methods of tumor extirpation have been considered standard of care. With the wider use of endoscopic methods, an updated systematic review in terms of treatment is warranted. Cases were identified using a MEDLINE and PubMed search. Relevant studies were identified, and data was extracted regarding patient demographics, presenting symptoms, tumor characteristics, treatment, and outcomes. A total of 128 cases were collected from 56 articles, consisting of case reports and series. The most common presenting symptoms were epistaxis, nasal obstruction, and facial pain/swelling/pressure. Computed tomography (CT) and X-ray were the most common modes of imaging during diagnosis and operative planning. The tumor often occupied multipl...

These defects have initially led to increased postoperative cerebrospinal fluid (CSF) leaks. The development of the vascularized pedicled nasoseptal flap (PNSF) has successfully reduced postoperative CSF leaks. Mucocele formation, however, has been reported as a complication of this technique. In this study, we analyze the incidence of mucocele formation after repair of SB defects using a PNSF. A retrospective review was performed from December 2008 to December 2011 to identify patients who underwent PNSF reconstruction for large ventral SB defects. Demographic data, defect site, incidence of postoperative CSF leaks, and rate of mucocele formation were collected. Seventy patients undergoing PNSF repair of SB defects were identified. No postoperative mucocele formation was noted at an average radiological follow-up of 11.7 months (range,...

A retrospective cohort study using the U.S. National Cancer Institute's SEER registry was performed to study the demographics and survival for SNAC from 1973 to 2009. Analysis was conducted based on race, gender, and stage. In total, 1270 cases of SNAC were analyzed for demographics and survival. Males accounted for 51.6% of cases, while females accounted for 48.4% of cases, amounting to a male to female ratio of 1.06:1.00. Disease specific survival at 5, 10, 15, and 20 years was 65.2%, 50.9%, 40.9%, and 36.5%, respectively. When analyzed by gender, females had higher survival than males, although this difference was not statistically significant. When analyzed by race, the category of other, which encompasses American Indian, Asian, Hispanic, and...

Males and females were found to have similar long-term survival curves, with 20-year survival of 30.68% and 26.35%, respectively. The overall incidence of SNSCC is declining. However, survival has not significantly improved in the last 3 decades. Race seems to influence the overall survival of this tumor. Future studies need to be conducted to investigate these dynamic trends related to SNSCC.

Patient data were stratified according to age, gender, race, grade, and extent of disease. Incidence trends were studied across the last 30 years and long-term disease-specific survival outcomes were compared across the different demographic parameters. A total of 1,129 cases of AciCC were identified, comprising of 672 (59.52%) females. Incidence trend analysis revealed significant changes in yearly incidence rates from 1973 to 2009 for male gender and white and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;others&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; races. Overall 5-year survival was 97.15%, 10-year survival was 93.81%, and 20-year survival was 89.74%. Significant differences in survival outcomes were noted for extent of disease. Patients exhibiting distant metastasis displayed the worse long-term prognosis at 21.99% 20-year disease-specific survival. Hazard ratios demonstrated a significant increase in mortality in patients with poorly differentiated, undifferentiated, and metastatic disease. Trends in incidence of AciCC are influenced by gender, race and age. Long-term survival of this rare malignant tumor is influenced by gender, grade, race, and extent of disease. Future studies need to be conducted to investigate these dynamic trends related to AciCC.

As such, it is an effective, objective bibliometric that can be used to evaluate academic otolaryngologists for decisions regarding appointment and advancement. In this study, we evaluate the impact of NIH funding on scholarly productivity in otolaryngology. Analysis of bibliometric data of academic otolaryngologists. Funding data for the 20 otolaryngology departments with the largest aggregate total of NIH grants for the fiscal years (FY) 2011 and 2012 was obtained using the National Institutes of Health Research Portfolio Online Reporting Tools Expenditures and Reports (RePORTER) Database. H-indices were calculated using the Scopus online database, and then compared to funding data at both the departmental and individual level. Faculty members in otolaryngology departments who received NIH funding had significantly greater research productivity and impact, as measured by the h-index, than their nonfunded peers. H-indices increased with greater NIH funding levels, and investigators with MD degrees tended to have higher mean NIH funding levels than those with PhDs. While there was no correlation between average h-index and NIH funding totals at the level of departments, there was greater correlation upon examination of NIH funding levels of individual investigators. The h-index has a strong relationship with, and may be predictive of, grant awards of NIH-funded faculty members in otolaryngology departments. This bibliometric may be useful in decisions regarding appointment and advancement of faculty members within academic otolaryngology departments.

This study reviews the published literature related to SNTCS. Clinical presentation, demographics, radiographic diagnosis, pathology, treatment, and management outcomes of this uncommon disease are reported. A systematic review in the published English literature was conducted. A MEDLINE/PubMed search and bibliographic examination of articles pertaining to SNTCS were performed. Each case was analyzed for patient demographics, clinical presentation, tumor location, diagnosis, treatment, and survival outcome. A total of 49 journal articles were included. Individual patient data were reported in 86 cases. The average age of the patients was 54.5 years (range, 0.1 to 85 years), with a strong male predilection (7:1). Average follow-up was found to be 38.9 months (range, 2 to 372 months). The most common treatment method was surgery with radiation therapy, utilized in 59.3% of patients. Out of 71 cases with reported outcome and follow-up, there were 21 cases of recurrence, 8 cases with metastasis, and 6 cases reporting both recurrence and metastasis. Forty-two out of 71 (59.2%) patients survived at the time of follow-up. This study describes the largest pool of SNTCS patients to date. SNTCS is a rare and aggressive malignant skull base tumor with a poor prognosis with frequent recurrence and metastasis. Although a variety of treatment paradigms have been reported in the literature, radical surgical resection followed by radiation therapy appears to be the most commonly used treatment option.

It is the most common sarcoma in children. In this study, we analyze the incidence and long-term survival for SNRMS using a national population-based database. The United States National Cancer Institute&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Surveillance, Epidemiology, and End Results (SEER) registry was utilized to calculate incidence and survival trends for SNRMS between 1973 and 2009. In addition, data were grouped by age, gender, race, and histopathological subtype. A total of 181 cases of SNRMS were analyzed for incidence trends, showing a 1.23:1 female to male ratio. While the overall incidence of SNRMS increased by 1.02% annually over the last 20years, this pattern was not equal amongst gender and racial groups. The incidence in males has increased, while in females incidence has decreased. An increase in incidence was noted in white and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;others,&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; but decreased in blacks. Using a total of 314 cases for survival analysis, we found that the rate in the white population has been consistently highest with a 5-year survival of 49.45%, 10- and 20-year survival of 48.81%. Survival rates in cases of embryonal SNRMS were also consistently higher than in cases of alveolar SNRMS. Overall incidence of SNRMS is increasing. Histologic subtype and race are important considerations in the long-term prognosis of SNRMS. Future studies will further elucidate gender and race related trends.
