Background: Aesthetic facial appearance following neurosurgical ablation of frontal fossa tumors is a primary concern for patients and neurosurgeons alike. Craniofacial reconstruction procedures have drastically evolved since the development of three-dimensional computed tomography imaging and computer-assisted programming. Traditionally, two-stage approaches for resection and reconstruction were used; however, these two-stage approaches have many complications including cerebrospinal fluid leaks, necrosis, and pneumocephalus.

Associations of BMI with body composition and health outcomes may differ between Asian and European populations. Asian populations have also been shown to have an elevated risk of type 2 diabetes, hypertension, and hyperlipidemia at a relatively low level of BMI. New surgical indication for Asian patients should be discussed by the expert of this field.

Objectives: Loss of functional and supporting architecture in the paraglottic space (PGS) necessitates augmentation to restore phonation and prevent aspiration. Our previous PGS reconstructions using an inferiorly based sternohyoid muscle flap have shown a propensity to fibrose over time, tethering the vocal fold inferolaterally. Poor voice outcomes have led us to explore other reconstructive options such as the laterally based vascularized fat flap described below.

Objective: To characterize surfactant protein A (SP-A) expression in human nasal tissue and correlate differential expression of SP-A with symptoms suggestive of allergic rhinitis.

Design: Allergic rhinitis symptom data were prospectively collected in the form of the Rhinitis Symptom Utility Index, the Rhinoconjunctivitis Quality of Life Questionnaire, and a Visual Analog Scale. Immunohistochemical staining for SP-A was performed on resected nasal tissue.

Objective: To define the gene expression patterns during the early phases of a bacterial middle ear infection in the rat model.

Method: Using cDNA gene array technology, we profiled the mRNA expression of 1176 genes in a rat model of acute otitis media. We identified changes in gene expression two-fold or greater 12 and 48 h after bilateral ME inoculation with either tryptic soy broth (TSB) or Streptococcus pneumoniae in TSB.

Objectives/hypothesis: To determine the incidence of voice disturbance as a presenting symptom of amyotrophic lateral sclerosis (ALS) and describe laryngologic features of ALS.

Study Design: Retrospective review.

Methods: Records of patients with voice disturbance at a voice center and ALS patients at a neurology clinic were reviewed from January 1998 to March 2003.
