The role of allergy in CRSwNP and CRSsNP continues to be controversial, with the level of evidence poor. Based on the available data, the recommendation is that allergy testing and treatment are an option in CRSwNP and CRSsNP.

Objective To determine clinicopathologic predictors of recurrence and survival in patients with spindle cell squamous cell carcinoma (SpSCC). Study Design Historical cohort study. Setting Tertiary care hospital. Subjects and Methods Forty-eight patients (mean age, 65.2 years; 35 men, 13 women) who underwent definitive treatment for pathologically confirmed SpSCC between 1987 and 2009 were identified and reviewed. The main outcome measures were time to recurrence and overall survival, while controlling for clinical and pathologic parameters (age, sex, TNM classification, stage, tumor subsite, smoking status, treatment modality, margin status). Results Of 48 patients, there were 25 oral cavity, 15 laryngeal, 7 oropharyngeal, and 1 maxillary sinus tumors. Treatment included surgery in 32, radiation in 9, and concurrent chemoradiation in 7 patients. The 3-year overall survival for the cohort was 62% with a median follow-up of 59 months; 52.1% (25/48) of patients developed a recurrence, and 88% (22/25) recurred locally or locoregionally. Recurrence occurred within 2 years in 72% (18/25) of patients. Age, sex, initial T and N classification, overall stage, tumor subsite, smoking status, treatment modality, and margin status were not predictive of recurrence or overall survival. Conclusion Patients with SpSCC are at high risk of developing locoregional recurrence, but no measured clinical or pathologic parameter was predictive of survival. Although overall survival is similar to that of patients with conventional SCC, closer follow-up should be considered in these patients to allow earlier detection and treatment of these locally aggressive tumors.

Long-term hearing results from intact canal wall mastoidectomy with tympanoplasty are excellent, with the majority of patients maintaining a small air-bone gap long term. The presence of a stapes and/or malleus handle confers improved long-term hearing outcomes.

The mammalian auditory epithelium (AE) cannot replace supporting cells and hair cells once they are lost. Therefore, sensorineural hearing loss associated with missing cells is permanent. This inability to regenerate critical cell types makes the AE a potential target for cell replacement therapies such as stem cell transplantation. Inserting stem cells into the AE of deaf ears is a complicated task due to the hostile, high potassium environment of the scala media in the cochlea, and the robust junctional complexes between cells in the AE that resist stem cell integration. Here, we evaluate whether temporarily reducing potassium levels in the scala media and disrupting the junctions in the AE make the cochlear environment more receptive and facilitate survival and integration of transplanted cells. We used sodium caprate to transiently disrupt the AE junctions, replaced endolymph with perilymph, and blocked stria vascularis pumps with furosemide. We determined that these three steps facilitated survival of HeLa cells in the scala media for at least 7 days and that some of the implanted cells formed a junctional contact with native AE cells. The data suggest that manipulation of the cochlear environment facilitates survival and integration of exogenously transplanted HeLa cells in the scala media.

In this sample of non-otolaryngology residents, a minority experienced a clinical rotation in otolaryngology during medical school or residency. This nonvalidated questionnaire also suggested significant deficiencies in basic otolaryngic knowledge in these residents. Identifying mechanisms to improve exposure to otolaryngology in the medical training curriculum is needed.
