Objectives: This study aims to analyze utilization and reimbursement trends in lingual and hyoid surgery for obstructive sleep apnea (OSA).

Methods: Annual retrospective data on lingual and hyoid OSA surgeries was obtained from the 2000-2021 Medicare Part B National Summary Datafiles. Current Procedural Terminology (CPT) codes utilized included 21,685 (hyoid myotomy and suspension [HMS]), 41,512 (tongue base suspension [TBS]), 41,530 (radiofrequency ablation of the tongue [RFT]) and 42,870 (lingual tonsillectomy [LT]).

Preoperative Predictors of Response to Hypoglossal Nerve Stimulation for Obstructive Sleep Apnea.

Objective: Hypoglossal nerve stimulation (HGNS) is an effective treatment for patients with obstructive sleep apnea (OSA) who fail continuous positive airway pressure (CPAP). We assessed the relationship between patient characteristics and response to HGNS.

Study Design: Retrospective cohort study.

Voice and swallowing outcomes following hypoglossal nerve stimulation for obstructive sleep apnea.

Objective: Hypoglossal nerve stimulation is an effective treatment for a subset of patients with Obstructive Sleep Apnea (OSA). Although multiple clinical trials demonstrate its efficacy, no previous literature explores the potential impact the stimulator has on swallowing and voice. Our primary objective is to evaluate patient reported post-operative changes in voice or swallowing following hypoglossal nerve stimulator placement.

Celecoxib Versus Placebo in Tonsillectomy: A Prospective, Randomized, Double-Blind Placebo-Controlled Trial.

Objectives: Celecoxib is a cyclooxygenase-2-specific inhibitor indicated to treat acute pain and pain secondary to osteoarthritis and rheumatoid arthritis. Surgical models of acute pain have demonstrated superior pain relief to placebo. The objective of this study was to test the safety and efficacy of celecoxib for pain relief after tonsillectomy compared to placebo.

Objective: Understand real-world prescription patterns for patients presenting with a first diagnosis of ARS and evaluate adherence to published medical guidelines.

Study Design: Retrospective administrative database analysis.

Setting: US-based outpatient settings.

Detection of metastatic head and neck squamous cell carcinoma using the relative expression of tissue-specific mir-205.

The presence of cervical lymph node metastases in head and neck squamous cell carcinoma (HNSCC) is the strongest determinant of patient prognosis. Owing to the impact of nodal metastases on patient survival, a system for sensitive and accurate detection is required. Clinical staging of lymph nodes is far less accurate than pathological staging.

Coblation-assisted lingual tonsillectomy for dysphagia secondary to tongue base hypertrophy.

Objectives: Lingual tonsillar hypertrophy is an underappreciated cause of dysphagia and is believed to impede swallowing function by inhibition of laryngeal elevation and epiglottic inversion due to mechanical interference by bulky tongue base tissue. We present a case of severe dysphagia secondary to idiopathic tongue base hypertrophy that was treated with coblation lingual tonsillectomy and tongue base reduction.

Methods: We report a case and discuss the relevant literature regarding tongue base hypertrophy and surgical interventions to treat the enlarged base of the tongue.

Modulation of cellular invasion by VEGF-C expression in squamous cell carcinoma of the head and neck.

Objective: To determine how vascular endothelial growth factor C (VEGF-C) affects tumor cell invasion and motility in squamous cell carcinoma of the head and neck (SCCHN).

Design: A molecular biology study. The VEGF-C coding sequence was cloned into an expression vector and stably transfected into the SCCHN cell line SCC116 to create the SCC116-VEGFC line.

Celecoxib toxicity is cell cycle phase specific.

Celecoxib inhibits proliferation and induces apoptosis in human tumors, but the molecular mechanisms for these processes are poorly understood. In this study, we evaluated the ability of celecoxib to induce toxicity in head and neck squamous cell carcinomas (HNSCC) and explored the relationships between celecoxib-induced cell cycle inhibition and toxicity in HNSCC. Celecoxib inhibited the proliferation of UM-SCC-1 and UM-SCC-17B cells both in vitro and in vivo, accompanied by G(1) phase cell cycle arrest and apoptosis.

Relative non-steroidal anti-inflammatory drug (NSAID) antiproliferative activity is mediated through p21-induced G1 arrest and E2F inhibition.

This study was performed to compare the relative antineoplastic activity of 10 different non-steroidal anti-inflammatory drugs (NSAIDs) in clinical use, and to investigate the underlying mechanisms of this activity in a squamous cell carcinoma of the head and neck model (SCCHN). A standard 5-day MTT assay was used to calculate IC(50) values in UM-SCC-1 cells for 10 NSAIDs, including celecoxib, rofecoxib, sulindac sulfide, sulindac sulfone, indomethacin, ketoprofen, flurbiprofen, naproxen, piroxicam, and aspirin. Celecoxib, a COX-2 specific inhibitor, was by far the most potent NSAID, with an IC(50) of 39.

Differential activity of sulindac metabolites against squamous cell carcinoma of the head and neck is mediated by p21waf1/cip1 induction and cell cycle inhibition.

Sulindac sulfide and sulindac sulfone have demonstrated anti-neoplastic and chemo-preventive activity against various human tumors, but few studies have examined the relative effectiveness of these drugs against squamous cell carcinoma of the head and neck (SCCHN). These compounds are metabolites of the nonsteroidal anti-inflammatory drug sulindac and differ in their ability to inhibit cyclooxygenase-2 (COX-2) enzyme function. Sulindac sulfide (the sulindac metabolite with COX-2 inhibitory function) demonstrated strong cell growth inhibition as measured by MTT and growth assays in UM-SCC-1 and SCC-25 cells, while sulindac sulfone had only moderate effect.

Transnasal, endoscopic vocal fold augmentation.

The practice of injection laryngoplasty under local anesthesia has become more common as both the indications for the procedure and the number of injectable substances increased. Modifications to the injection techniques used for vocal fold augmentation have been described over the last decade that reflect changes in the established percutaneous and transoral approaches. These percutaneous and transoral injection techniques for the treatment of dysphonia secondary to glottic incompetence are well described and provide an adequate approach for most cases.

Oral melanoacanthoma: a case report, a review of the literature, and a new treatment option.

Objectives: Oral melanoacanthoma is a rare condition that presents as a pigmented, painful lesion, most commonly on the buccal mucosa. Argon plasma coagulation is a new treatment option for benign oral lesions and is hypothesized to be efficacious for this rare mucosal disorder.

Methods: Treatment of a case and a review of the English-language literature were performed.

Long-term quality of life for surgical and nonsurgical treatment of head and neck cancer.

Objective: To compare the long-term, health-related quality-of-life outcomes in patients with advanced head and neck cancer (HNC) treated with surgery and postoperative radiation therapy (SRT) or concurrent chemotherapy and radiation therapy (CRT).

Design: Matched-pair study comparing patients with advanced HNC treated with SRT or CRT at least 12 months after treatment. Patients completed 2 validated surveys addressing HNC-specific outcomes and depressive symptoms and provided information on employment and tobacco and alcohol use.

Reversal of cisplatin resistance with a BH3 mimetic, (-)-gossypol, in head and neck cancer cells: role of wild-type p53 and Bcl-xL.

Organ preservation protocols in head and neck squamous cell carcinoma (HNSCC) are limited by tumors that fail to respond. We observed that larynx preservation and response to chemotherapy is significantly associated with p53 overexpression, and that most HNSCC cell lines with mutant p53 are more sensitive to cisplatin than those with wild-type p53. To investigate cisplatin resistance, we studied two HNSCC cell lines, UM-SCC-5 and UM-SCC-10B, and two resistant sublines developed by cultivation in gradually increasing concentrations of cisplatin.

Molecular profiling and the identification of genes associated with metastatic oral cavity/pharynx squamous cell carcinoma.

Objective: To investigate differences in gene expression profiles between oral cavity/oropharynx squamous cell carcinoma (OC/OP SCC) primary tumors that have metastasized to cervical lymph nodes and nonmetastatic OC/OP SCC tumors.

Design: Oligonucleotide microarray analysis of primary tumors was used to produce gene expression profiles. Profile comparisons between metastatic and nonmetastatic tumors were performed using principal component analysis, t test, and fold change differences.

Genetically targeted radiotherapy of head and neck squamous cell carcinoma using the sodium-iodide symporter (NIS).

Background: Gene therapy that uses delivery of the sodium-iodide symporter (NIS) gene followed by radioiodide administration has been proposed as a novel form of radiotherapy for nonthyroidal cancers.

Methods: In vitro [(125)I] iodide accumulation and efflux from cells was determined after treatment with an NIS-expressing adenovirus (Ad-NIS). A clonogenic survival assay and tumor growth experiment that used athymic mice were used to demonstrate the in vitro and in vivo cytotoxicity of Ad-NIS treatment and [(131)I] iodide delivery.

Validation of tissue microarrays using p53 immunohistochemical studies of squamous cell carcinoma of the larynx.

Tissue microarrays are a powerful new tissue-conserving technology in the study of cancer, allowing simultaneous study of a large number of tumor specimens. We sought to ascertain the utility of tissue microarrays in head and neck cancer pathology using squamous cell carcinoma of the larynx as a model system. Whole-specimen slides from 44 different laryngeal squamous cell carcinomas were stained for p53 expression.

Expression of Bcl-2 family proteins in advanced laryngeal squamous cell carcinoma: correlation with response to chemotherapy and organ preservation.

Objectives/hypothesis: Induction chemotherapy and definitive radiation therapy in advanced laryngeal cancer has been shown to achieve survival rates that are similar to total laryngectomy and postoperative radiation therapy. In patients with advanced laryngeal cancer, quality of life can be significantly enhanced by treatment regimens that preserve the larynx. However, which patients will respond best to organ preservation protocols remains unknown.
