Gamma knife radiosurgery for vestibular schwannomas: results of hearing preservation in relation to the cochlear radiation dose.
This study was designed to evaluate hearing preservation after gamma knife radiosurgery (GKRS) and to determine the relation between hearing preservation and cochlear radiation dose in patients with a sporadic vestibular schwannoma (VS). ⋯ Hearing preservation is correlated to the maximal radiation dose at the cochlea. The purpose of developing GKRS techniques was to avoid collateral damage in healthy tissues. This study emphasizes the need for exact radiation planning to reduce the cochlear radiation dose if the hearing is to be preserved. Laryngoscope, 2009.

Malakoplakia is a rare, chronic inflammatory condition characterized by defective macrophage function. The majority of cases involve the genitourinary tract, but isolated cases have been reported from other organ systems including one prior report involving the maxillary sinus. ⋯ Sinus-specific clinical aspects will be discussed including diagnostic and treatment considerations.

To determine what characteristics and comorbidities are associated with a higher rate of complications in patients undergoing nasal reconstruction with a forehead flap. ⋯ Smokers with full-thickness defects are shown to be at greater odds for developing a postoperative complication.

A prospective study of endoscopic expanded endonasal approaches (EEA) with nasoseptal flap reconstructions revealed anecdotal evidence of less available relative septal length in pediatric patients. Our goal is to use radioanatomic analysis of computed tomography (CT) scans to determine limitations of the nasoseptal flap in pediatric skull base reconstruction and to describe clinical outcomes after using the nasoseptal flap in six pediatric patients. ⋯ : The pedicled nasoseptal flap may not be a viable option for EEA reconstruction in children <10 years of age. This flap is a reliable option in patients >14 years of age, as their septums are comparable to adults. Patients 10 years to 13 years of age require careful consideration of facial analysis and preoperative radioanatomic evaluation on an individual basis. Laryngoscope, 2009.
