Treatment, Survival, and Demographics in Temporal Bone Malignancies: A Pooled Data Analysis.

Temporal bone malignancies are relatively uncommon tumors. Their location adjacent to vital structures such as the carotid artery, jugular vein, otic capsule, and temporal lobe can make their treatment potentially challenging. The purpose of this study was to compare outcomes in temporal bone malignancies obtained via pooled literature data. The study sought to examine factors affecting survival in temporal bone malignancies based on the studies in the existing published literature. A systematic search was conducted on the PubMed (Medline), Embase, and Google Scholar databases to identify relevant studies from 1951 to 2022 that described the treatment of temporal bone malignancies. Articles that fulfilled the inclusion criteria were assessed and analyzed by the author. The literature search identified 5875 case series and case reports, and 161 of them contained sufficient data to be included in the pooled data analysis, involving a total of 825 patients. Multivariate analysis of the pooled literature data showed that overall stage, presence of facial palsy, and surgical margin status significantly affected overall survival (OS), while overall stage and presence of facial palsy significantly affected disease-free survival (DFS). To summarize, this study examined pooled survival data on demographics, treatment, and survival of patients with temporal bone malignancies utilizing an extensive literature-based pooled data meta-analysis. Overall stage, facial nerve status, and surgical margin status appeared to most strongly affect survival in patients with temporal bone malignancies.

An Analysis of Biologic Therapies in Patients With Asthma and Chronic Rhinosinusitis.

Background Asthma, Allergic rhinitis (AR), Chronic Obstructive Pulmonary Disease (COPD), Eczema, and Chronic Rhinosinusitis with Sinonasal Polyposis (CRSwNP) are illnesses often characterized by type 2 (T2) inflammation, wherein T helper (Th) cells release pro-inflammatory cytokines such as IL (interleukin)-4, IL-5, IL-9, and IL-13. This response may also promote the production of IgE and an increase in/activation of serum eosinophils. In the aforementioned type 2 inflammatory diseases, this immune response can cause excess mucous production, inflammation of the airways, other atopic responses when patients are exposed to certain environmental allergic triggers. Relatively new biologic monoclonal antibody therapies such as dupilumab (blocks IL-4 and IL-13), benralizumab (blocks IL-5), mepolizumab (blocks IL-5), and omalizumab (blocks IgE Fc/fragment of crystallization region) offer novel therapeutic targets that more specifically and directly block type 2 inflammatory responses. Methods To examine the effect of monoclonal antibody biologic therapies on patient indicators of type 2 inflammation, a retrospective analysis of 193 patients on biologic therapy was conducted, and these patients were compared to 48 control patients with type 2 inflammatory diseases who did not initiate biologic therapy. Total Lund-MacKay radiographic score, FEV1 (forced expiratory volume in the first second), FEF25-75 (forced expiratory flow from 25-75% of the forced vital capacity curve), annualized pulmonary exacerbations, oral corticosteroid dose, and serum eosinophils were recorded at baseline (zero months), and at three, six, nine, and twelve months after initiation of biologic therapy. Least squares mean data and the percent change from the baseline of least squares mean for the biologic and control groups were compared. Results Omalizumab was the most common biologic therapy prescribed. Control patients were younger than patients who initiated biologic therapy. Patients on biologic therapy had statistically significant reductions in Lund-MacKay score, improvements in FEV1 and FEF25-75, reductions in serum IgE levels, and reductions in serum Eosinophils. Patients on biologic therapy also had statistically significant reductions in annualized pulmonary exacerbations and oral corticosteroid dose compared to controls. Conclusions Patients with a variety of type 2 inflammatory conditions appear to have significant improvements in lung function, radiographic sinusitis, and serum markers of type 2 inflammation after initiation of biologic therapy versus controls. These therapeutic medications appear to significantly improve type 2 inflammatory disease course in patients who can tolerate these medications.

Olfactory Radioanatomical Findings in Patients With Cardiac Arrhythmias, COVID-19, and Healthy Controls.

Background Clinical hyposmia and anosmia are commonly seen, most frequently with either post-inflammatory, age-related, or idiopathic causes being most frequent. Actual anatomical abnormalities of the olfactory groove or olfactory bulb are far less common. A recent case report showing a possible link between congenital olfactory bulb agenesis and Wolff-Parkinson-White syndrome suggested that there may be a relationship between cardiac arrhythmia and olfactory bulb development. While Kallmann syndrome (KS) is the classic syndrome involving olfactory bulb agenesis and hypogonadotropic hypogonadism, this case report and a prior report noting isolated hypogonadotropic hypogonadism and the Wolff-Parkinson-White syndrome suggest there may be more rare associations between cardiac arrhythmia and olfactory groove abnormalities. Methods A retrospective study was conducted to attempt to elucidate whether there may be a link between cardiac arrhythmias and olfactory anatomical abnormalities. The olfactory bulb volume (OBV) and olfactory sulcus depth (OSD) of 44 patients with cardiac arrhythmias were compared to 43 healthy control patients. Additionally, 11 patients with acute COVID-19 were also compared in those groups. Patients were seen between September and December 2020. Available MRI images were utilized. Results The average right and left olfactory bulb volume was 29.42±18.17 mm3 and 25.67±15.29 mm3 for patients with cardiac arrhythmia, 40.79±30.65 mm3 and 38.95±21.87mm3 for healthy controls, and 21.30±15.23 mm3 and 17.75±9.63 mm3 for COVID-19 patients. The average right and left olfactory sulcus depth was 7.68±1.31 mm and 7.47±1.56 mm for patients with cardiac arrhythmia, 10.67±1.53 mm and 10.62±1.67 mm for controls, and 7.91±0.99 mm and 8.02±0.88 mm for COVID-19 patients. The right and left olfactory bulb volume difference versus controls was significant for cardiac arrhythmia patients (p=0.028 and p=0.0038) and for COVID-19 patients (p=0.047 and p=0.0029), and the right and left olfactory sulcus depth difference versus controls was significant for cardiac arrhythmia patients (p<0.0001 and p<0.0001) and for COVID-19 patients (p<0.0001 and p<0.0001). Both COVID-19 and cardiac arrhythmia patients were, on average, significantly older than controls. On multivariate analysis, cardiac arrhythmia or COVID-19 diagnosis did not significantly correlate with smaller olfactory bulb volume, but older age, cardiac arrhythmia diagnosis, and COVID-19 diagnosis did significantly correlate with smaller olfactory sulcus depth. On multivariate analysis, older age was significantly correlated with cardiac arrhythmia diagnosis and COVID-19 diagnosis. Conclusions Olfactory bulb volume and olfactory sulcus depth in both cardiac arrhythmia and COVID-19 patients appeared significantly smaller than in controls. Cardiac arrhythmia and COVID-19 patients were significantly older than controls. Age, as well as genetic predisposition, may contribute to a difference in the radiographic olfactory anatomical findings in patients with cardiac arrhythmias and COVID-19.

Association of olfactory neuropathy spectrum disorder and Wolff-Parkinson-White syndrome: A Report of a case.

Olfactory neuropathy spectrum disorder is characterized by hyposmia or anosmia and hypoplastic or absent olfactory bulbs. There may be an association between olfactory neuropathy spectrum disorder and Wolff-Parkinson-White syndrome.

Lemierre Syndrome: A Meta-analysis.

Introduction Lemierre syndrome, or postpharyngitis anaerobic sepsis, is an infrequent but life-threatening infection that often involves thrombosis of the internal jugular vein. The role of anticoagulation in addition to antibiotics and surgical treatment remains uncertain. Objectives 1) To perform a meta-analysis on outcomes and treatment of Lemierre syndrome; and 2) to evaluate the effect of anticoagulation in Lemierre syndrome on vessel recanalization and on mortality. Data Synthesis A Pubmed database search was conducted using the keywords Lemierre syndrome . A total of 427 studies were identified and reviewed. Data were extracted on patient demographics, treatment type including use and type of anticoagulation, type of antibiotics, presence and location of vessel thrombosis, presence of cranial neuropathies, recanalization of thrombosed vessels on follow-up imaging, organisms isolated on wound or blood cultures, and mortality. The primary outcome variables examined were the effect of anticoagulation on vessel recanalization and mortality. After the review, 359 studies totaling 394 patients between 1990 and 2017 had partial or complete data that could be analyzed. In total, 50 patients had sufficient data on the effect of anticoagulation on vessel recanalization, and 194 had sufficient data on the effect of anticoagulation on mortality. The odds ratio for anticoagulation and vessel recanalization was 1.6 (95% confidence interval = 0.3 to 9.4; p = 0.6). The odds ratio for anticoagulation and death was 0.6 (95% confidence interval = 0.1 to 2.9; p = 0.5). Conclusion The present meta-analysis did not demonstrate a statistically significant effect on vessel recanalization or mortality for patients treated with anticoagulation versus patients not anticoagulated in the Lemierre syndrome literature.

Comparing Kadish and Modified Dulguerov Staging Systems for Olfactory Neuroblastoma: An Individual Participant Data Meta-analysis.

OBJECTIVE: To compare the Kadish and the modified Dulguerov staging of individual participants to determine the impact of stage and other prognostic factors on disease-free (DFS) and overall survival (OS). DATA SOURCES: Systematic review of EMBASE, MEDLINE, Cochrane Library, and CINAHL databases. REVIEW METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) was followed for this study. Articles including patients with olfactory neuroblastoma (ONB) staged with both Kadish and Dulguerov staging systems were reviewed. The raw data from eligible studies were requested to perform an individual participant data (IPD) meta-analysis. RESULTS: Pooled data from 21 studies representing 399 patients with ONB undergoing treatment with curative intent showed that increasing age, treatment with chemotherapy, and positive or unreported margin status portended worse DFS (P < .05). Increasing stage for both Kadish and Dulguerov staging systems was prognostic for worse DFS and OS (P < .05), with Kadish C representing a heterogeneous group with regard to outcome and corresponding Dulguerov T stage. Using the Akaike information criterion, the Dulguerov staging system had superior performance to the Kadish system for DFS (1088.72 vs 1092.54) and OS (632.71 vs 644.23). CONCLUSION: This study represents the first IPD meta-analysis of ONB directly comparing the outcomes of Kadish and Dulguerov staging systems in patients treated with primary surgery. Both systems correlated with DFS and OS, with superior performance in the Dulguerov system. Furthermore, the Kadish C group represented a heterogeneous group with regard to outcomes after stratification by the Dulguerov system. Dulguerov T4 patients had the worst outcome, with most being approached with open resection.

The supraseptal ethmoid sinus cell: A previously unreported ethmoid sinus variant.

To the author's knowledge, this is the first reported case in the literature of a supraseptal ethmoid sinus cell, located between the nasal septum and ethmoid roof. Such a cell, while rare, should be recognized and dissected carefully to prevent skull base injury and cerebrospinal fluid leak.

Survival in sinonasal and middle ear malignancies: a population-based study using the SEER 1973-2015 database.

BACKGROUND: The sinuses, nasal cavity, and middle ear represent a rarer location of head and neck malignancy than more common sites such as the larynx and oral cavity. Population-based studies are a useful tool to study the demographic and treatment factors affecting survival in these malignancies. METHODS: Population-based database search of the Survival, Epidemiology, and End Results (SEER) database from 1973 to 2015 for malignancies involving the nasal cavity, paranasal sinuses, and middle ear. Data were analyzed for demographics, treatment type, stage, primary site and histopathologic type. Kaplan-Meier analysis was used to assess and compare survival. RESULTS: A total of 13,992 cases of sinonasal or middle ear malignancy were identified and analyzed. The majority of patients were between ages 50 and 80 at the time of diagnosis. Overall 5-, 10-, and 20-year survival was 45.7%, 32.2%, and 16.4%, respectively. Lymph node metastasis was reported in 4.4% of patients, while distant metastasis was present in 1.5% of cases. On univariate analysis surgical vs. nonsurgical treatment, sex, race, age at diagnosis, T stage, N stage, M stage, AJCC overall stage, primary site, tumor grade, and histopathologic subtype significantly affected survival. On multivariate analysis age, race, sex, primary site, overall AJCC stage, surgical vs. nonsurgical treatment, and T, N, and M stage remained significant predictors of overall survival. CONCLUSIONS: Malignancies of the nasal cavity, paranasal sinuses, and middle ear account for a minority of overall head and neck cancers. The overall 5-, 10-, and 20-year survival for these malignancies is relatively low. Higher T, N, M, and overall stage and higher tumor grade is associated with lower survival. Patients treated with surgery as part of the treatment regimen had higher overall survival. Demographics and primary site also significantly affect survival. Certain histopathologic subtypes were associated with poorer survival.

Odontogenic necrotizing fasciitis: a systematic review of the literature.

BACKGROUND: While odontogenic soft tissue infections of the head and neck are common, progression to necrotizing fasciitis is relatively rare. Necrotizing fasciitis is a potentially life-threatening and rapidly progressive soft tissue infection that can lead to significant skin and soft tissue loss, mediastinitis, vascular thrombosis or rupture, limb loss, organ failure, and death. METHODS: A PubMed literature search was conducted for case reports and case series on odontogenic necrotizing fasciitis. Individual patient data was analyzed and compiled and demographic, treatment, microbiology, and mortality data were extracted. Fisher's exact test was used to examine the relationship between death from odontogenic necrotizing fasciitis and diabetes mellitus (DM) and human immunodeficiency virus (HIV) positivity. RESULTS: A total of 58 studies totaling 164 patients were identified. Thirty-three patients had DM and 3 were HIV +. All patients underwent aggressive surgical debridement and treatment with IV antibiotics. Twenty patients were also treated with hyperbaric oxygen. There were 16 deaths reported, for a mortality rate of 9.8%. The mortality rate among patients with DM was 30.3 and 0% among HIV positive patients. There was a statistically significant increase in the mortality rate in DM patients with odontogenic necrotizing fasciitis (p = 0.0001, odds ratio for death 9.1). CONCLUSIONS: Necrotizing fasciitis arising from odontogenic infection is a rapidly progressive and life-threatening illness. Prompt recognition of the infection, aggressive and often serial surgical debridement, and aggressive broad-spectrum antibiotics are necessary to prevent serious morbidity and mortality. Patients with diabetes mellitus are at a significantly increased risk of death from odontogenic necrotizing fasciitis.

Epithelial-myoepithelial carcinoma: a population-based survival analysis.

BACKGROUND: Epithelial-myoepithelial carcinoma is an uncommon malignant neoplasm seen most frequently in the salivary glands, representing approximately 1 to 2% of salivary gland tumors. Less than 600 cases have been reported in the literature since its initial description in 1972. The aim of this study was to examine demographic, site, stage, and survival factors in patients with epithelial-myoepithelial carcinoma. METHODS: The 1973-2014 SEER (Surveillance, Epidemiology, and End Results) cancer database was queried for patients treated for epithelial-myoepithelial carcinoma. The data was analyzed for patient T (tumor), N (nodal), and M (metastasis) stage, tumor site, and demographic characteristics. The Kaplan-Meier model was used to estimate actuarial survival. RESULTS: A total of 468 patients were identified. White patients represented 78.0% of the total. There were 291 female patients and 177 male patients. Overall 5-, 10-, and 20-year survival was 72.7%, 59.5%, and 38.3%, respectively. Mean survival time was 165.5 months. Parotid gland was the most common site with 57.7% of patients, with submandibular gland representing 9.8% of patients. Distant metastasis (M) status was unknown in 33.3%, with 2.6% being M1, 3.0% being MX, and 61.1% M0. Nodal metastasis (N) status was unknown in 33.3%, while 4.4% were N+, 4.7% were NX, and 57.5% were N0. 88.2% of patients had surgery as part or all of the treatment regimen. Univariate Kaplan-Meier analysis showed that AJCC overall stage, primary tumor (T) stage, nodal (N) stage, presence of distant metastasis (M1), age at diagnosis, race, and non-surgical treatment significantly affected survival. On multivariate analysis age, race, AJCC stage, T, N, M stage, and treatment type were significant. CONCLUSIONS: Epithelial-myoepithelial carcinoma is a malignant, histologically biphasic neoplasm most frequently seen in the parotid gland. The nodal and distant metastasis rates are low. Age at diagnosis, race, AJCC stage, T, N, M stage, and treatment type all significantly affected survival.

Treatment, outcomes, and demographics in sinonasal sarcoma: a systematic review of the literature.

BACKGROUND: Sarcomas comprise a diverse group of soft tissue mesenchymal malignancies. The sinuses and nasal region are a relatively rare site of sarcomas. METHODS: Retrospective review of the literature on sinonasal sarcomas from 1987-2017. Data were analyzed for demographics, treatment type, stage, and histopathologic type. Kaplan-Meier analysis was used to assess and compare survival. RESULTS: A total of 198 cases of sinonasal sarcoma were identified and analyzed. The median age at diagnosis was 39 years. Overall 5-, 10-, and 20-year survival was 61.3%, 58.9%, and 49.1%, respectively, and disease-free 5-, 10-, and 20-year survival was 53.2%, 49.1%, and 38.3%, respectively. Lymph node metastasis was present at diagnosis in 3.0% of cases, and distant metastasis was present in 3.5% of cases. On univariate analysis T stage, overall stage, treatment type, histopathologic subtype, and presence of distant metastasis significantly affected survival. On multivariate analysis overall stage alone significantly predicted overall survival. Open vs. endoscopic surgery, total radiation dose, and presence of neck metastasis did not significantly affect survival. Combined modality treatment was associated with higher survival rates than single modality therapy. CONCLUSIONS: Sinonasal sarcoma is a relatively rare malignancy. Lower T and overall stage, lack of distant metastasis, and multimodality therapy were associated with improved survival. Certain histopathologic subtypes were associated with poorer survival.

Endoscopic repair of lateral sphenoid Encephaloceles: a case series.

BACKGROUND: Lateral sphenoid encephaloceles present a surgical challenge. These encephaloceles may be difficult to access given their lateral location and proximity to the neural and vascular structures of the sphenoid floor, pterygopalatine fossa, and lateral and superior sphenoid walls. Additionally, many patients have idiopathic intracranial hypertension, increasing the risk of recurrence. When untreated or undiscovered, these encephaloceles increase the risk of meningitis. METHODS: All consecutive endoscopic repairs of lateral sphenoid encephaloceles by a single surgeon from 2012 to 2017 were analyzed for method of repair, complications, and recurrence rate. Odds ratio for recurrence of CSF leak for Alloderm inlay/abdominal fat sphenoid obliteration/nasoseptal flap with multilayer repair vs. other method (Alloderm onlay/contralateral nasoseptal flap or free mucosal graft) was compared, and Fischer's exact test was used to calculate the two-sided p-value for the two repair methods. RESULTS: The success rate (no recurrence of cerebrospinal fluid rhinorrhea) for Alloderm inlay/abdominal fat onlay/nasoseptal flap onlay was 100% while for Alloderm onlay/contralateral nasoseptal flap + free mucosal graft the success rate was 0%. For any nasoseptal flap repair vs. free mucosal graft the success rates were 83.3% and 16.7% respectively. The success rate for Alloderm inlay/abdominal fat onlay/nasoseptal flap onlay vs. Alloderm onlay/contralateral nasoseptal flap + free mucosal graft was statistically significant (p = 0.048), but the success rate for any nasoseptal flap repair vs. free mucosal graft was not significant (p = 0.29). The success rate for patients without post-op lumbar drain vs. with post-op lumbar drain was also nonsignificant (p = 0.29). CONCLUSIONS: In the author's hands Alloderm inlay/abdominal fat onlay/nasoseptal flap onlay was superior to other repair methods (Alloderm onlay/contralateral nasoseptal flap or free middle turbinate mucosa onlay graft). The complication rate was low. Post-operative lumbar drainage did not affect the success rate.

Orbital pseudotumor as a result of chronic sinusitis in an HIV-positive patient.

Orbital inflammatory pseudotumor is an infrequent lesion that may mimic malignancy and may be associated with autoimmune disease. Orbital pseudotumor is in the differential in any patient with an orbital mass, especially in the setting of chronic infection or immunosuppression. This HIV-positive patient presented with chronic sinusitis and orbital pseudotumor.

Post-operative budesonide irrigations for patients with polyposis: a blinded, randomized controlled trial.

OBJECTIVE: To compare normal saline (NS) vs. NS+budesonide irrigations in post- functional endoscopic sinus surgery (FESS) patients with chronic rhinosinusitis with polyposis (CRSwNP). Currently, no evidence exists for NS+budesonide irrigation over NS irrigation alone. STUDY DESIGN: Prospective, single-blind, randomized controlled trial. METHODS: Subjects were prospectively enrolled to NS or NS+budesonide arms. Patients were evaluated at pre-operative and three post-operative visits (POV): POV1 (1-2 weeks post-op), POV2 (3-8 weeks post-op), and POV3 (3-6 months post-op). Patients were evaluated by three quality of life (QOL) questionnaires (SNOT-22, RSOM-31, and RSDI) and two olfaction scores (UPSIT and the PEA test). RESULTS: Fifty patients were randomized, with 25 patients in the NS arm and 25 patients in the NS+budesonide arm. Two patients had unexpected pathology and were excluded from the study. By POV2 and POV3, patients experienced a significant improvement in all three QOL surveys, although the degree of improvement between arms was not significant up through POV3. Neither arm experienced significant olfactory improvement up through POV3. CONCLUSIONS: While both NS and NS+budesonide treatments improve QOL for post-FESS patients, neither intervention significantly increases QOL as compared to the other. Olfaction was not significantly improved in either treatment group.

Beyond the "central sinus": radiographic findings in patients undergoing revision functional endoscopic sinus surgery.

BACKGROUND: Functional endoscopic sinus surgery (FESS) is widely used by otolaryngologists to treat chronic rhinosinusitis (CRS). The sinonasal anatomy and pathology found in patients with CRS varies widely, as does the FESS technique practiced by otolaryngologists. Variations in the completeness of cell group dissection, combined with the technical challenge of angled endoscopy, result in a wide variation of the post-FESS cavities harboring persistent disease. The purpose of this study was to identify previously incompletely dissected anatomic structures associated with mucosal thickening found in patients undergoing revision FESS for persistent or recurrent CRS. METHODS: Retrospective review of axial, coronal, and sagittal computed tomography (CT) scans of patients undergoing revision FESS by 3 fellowship-trained rhinologists at a tertiary referral center. RESULTS: The CT scans of 55 patients undergoing revision FESS were reviewed. The most frequent radiographic findings were residual anterior and posterior ethmoid cells or septations, found in 65% of sides and 75% of patients. In addition, residual anterior ethmoid agger nasi cells, unopened sphenoid, and residual uncinates were found in 52%, 51%, and 46% of sides, respectively. A large percentage of the patients demonstrated residual ethmoid cells present on the lamina papyracea and skull base, with a lower number found posterior to the middle turbinate basal lamella. A greater number of residual right-sided vs left-sided ethmoid cells was noted, with the difference being significant (p < 0.05) at the skull base. CONCLUSION: Analysis of CT scans of patients undergoing revision FESS for persistent or recurrent CRS frequently reveals persistent anatomical structures or incompletely resected cells associated with persistent mucosal thickening. Meticulous, complete cell group dissection combined with use of angled endoscopy along with identification of possible predisposing structures may aid in the reduction of need for revision surgery.

Evidence-based practice: endoscopic skull base resection for malignancy.

Successful outcomes of endoscopic approaches to benign sinonasal tumors have launched interest in expanding its use for sinonasal malignancy. Because of the heterogeneity and rarity of sinonasal malignancy, evidence for clinical outcomes of endoscopic approaches versus traditional craniofacial resection is low. Using the Oxford Center for Evidence-based Medicine guidelines, we present the existing evidence comparing both techniques for a variety of sinonasal malignancies.

Survival in Sinonasal Melanoma: A Meta-analysis.

UNLABELLED: Sinonasal melanoma is an uncommon tumor which carries a poor prognosis and high rates of local and regional recurrence and distant metastasis. While surgical resection is the mainstay of treatment, the utility of multimodality therapy has not been well studied or established. We sought to better evaluate the optimal treatment modality for sinonasal melanoma. We reviewed 39 case reports involving 423 patients with sinonasal melanoma and present a meta-analysis comparing survival by treatment modality. The two-tailed p-value for survival by treatment modality was determined. The number of primary site/local, regional, and distant recurrences was determined where data was available. There was a nonsignificant increase in survival for patients treated with surgery + radiotherapy versus surgery alone. There was a statistically significant increase in survival for surgery + chemotherapy versus chemotherapy alone and versus surgery alone. Patients treated with combined surgery, radiation, and chemotherapy had a statistically shorter survival interval than patients treated with surgery + chemotherapy, which may reflect more advanced disease in patients treated with triple therapy. There was no statistically significant increase in survival found for the addition of radiation to surgery. This meta-analysis demonstrates that multimodality therapy, particularly the addition of chemo-or immunotherapy to surgery, may increase survival in a subset of patients. Radiation therapy did not appear to increase survival. There may be a significant increase in overall survival with combined modality therapy with surgery and chemo/immunotherapy versus single modality therapy. LEVEL OF EVIDENCE: III. Grade of recommendation: C.

Cholesterol granuloma of the petrous apex.

The traditional approaches to symptomatic cholesterol granuloma (CG), the most common benign pathologic lesion of the petrous apex, have historically been transotic, including middle fossa, translabyrinthine, retrocochlear, or infra- or retrolabyrinthine approaches. These approaches were often fraught with risk to the vestibular or cochlear apparatus, the need for brain retraction, or lack of a natural drainage pathway after marsupialization of the granuloma. This article reviews the literature on the transnasal approach to petrous apex CGs, including medial, medial with carotid medialization, and transpterygoid approaches. Of the 19 reported CGs treated with endoscopic drainage, only one recurrence was noted.

Contracture related airway obstruction (CRAO) treated successfully with incisional release.

OBJECTIVE: To describe the delayed airway obstruction that can result from anterior cervical burns and report a case of successful decannulation following incisional release and full-thickness skin grafting (FTSG). METHODS: Case report from a tertiary care academic children's hospital. RESULTS: Direct laryngoscopy demonstrates a significant improvement in the upper airway immediately following an anterior cervical incisional release. The patient was then able to be decannulated on postoperative day 10. CONCLUSIONS: Cervical contracture is an important consideration in children with airway obstruction following burns to the upper chest, anterior neck and face, and may be treated successfully with incisional release and FTSG.
