We discuss a novel approach to resecting a large 1.5 cm intracordal schwannoma via direct laryngoscopy with combined endoscopic and microlaryngoscopic techniques. Removing relatively bulky masses within the vocal cord soft tissue can be challenging secondary to difficult visualization of the operative field during direct laryngoscopy.

Chondrolaryngoplasty is a well-described surgical procedure most commonly performed as part of facial feminization surgery for transgender patients with a diagnosis of gender dysphoria. A complete understanding of relevant neck anatomy and laryngeal function is critical to optimizing surgical outcomes. The overall goal of the procedure is to maximally reduce the thyroid cartilage prominence while preserving laryngeal integrity and minimizing the risk of external scarring.

Objectives/hypothesis: To elucidate and review current literature on the surgical technique for laryngochondroplasty in male-to-female transgender patients. To determine the degree of benefit afforded to male-to-female transgender patients by laryngochondroplasty using the Glasgow Benefit Inventory (GBI).

Study Design: Retrospective case series.

Social media is no longer new, even in the professional medical world. It is an established and relatively public medium, and all users would do well to understand the risks associated with it. Medical personnel-whether medical student or staff physician-must familiarize themselves with it to ensure positive outcomes.

The ability to speak and communicate with one's voice is a unique human characteristic and is fundamental to many activities of daily living, such as talking on the phone and speaking to loved ones. When the larynx is removed during a total laryngectomy (TL), loss of voice can lead to a devastating decrease in a patient's quality of life, and precipitate significant frustration over their inability to communicate with others effectively. Over the past 50 years there have been many advances in techniques of voice restoration after TL.

Introduction: We describe the first known case of bilateral basaloid squamous cell carcinoma of the parotid gland, and we review existing literature.

Case Presentation: A previously healthy, 70-year-old white man presented with a 2-cm enlarging mass in the tail of the right parotid gland. Magnetic resonance imaging and computed tomography showed ipsilateral pathologic adenopathy.

Case Presentation: A 74-year-old woman presented to the Head and Neck Surgery clinic with a 4-year history of a slowly growing, painful, left-sided neck mass in the tail of the parotid gland. Fine-needle aspiration suggested well-differentiated adenocarcinoma.

Discussion And Results: The patient underwent a superficial parotidectomy and super-selective neck dissection (level 2).

Secondary oral cavity neoplasms are rare. We describe a case of an indurated, nonulcerating gingival lesion in a 59-year-old nonsmoking man with no family history of lung cancer. The lesion was the presenting symptom of metastatic lung adenocarcinoma.

Objectives/hypothesis: To establish risk of hemorrhage in patients with varices compared to those without, determine additional risk factors, and make evidence-based treatment recommendations.

Study Design: Retrospective cohort study.

Methods: Patients who were vocal performers presenting for care during a 24-month period were analyzed to determine incidence of hemorrhage.

Objectives/hypothesis: Although onabotulinum neurotoxin A (BoNTA) has been used for over three decades for the treatment of adductor spasmodic dysphonia, no study has been performed to look at the trend of BoNTA dosages across time. The goal of this study is to evaluate the dosage trends to determine if the dosage necessary for voice improvement in patients increases over time.

Study Design: Charts were reviewed for patients with 15 years or more of experience.

The ability to speak and communicate vocally is a unique human characteristic that is often taken for granted but is fundamental to many activities of daily living. Loss of voice after total laryngectomy can lead to a serious decrease in quality of life and can precipitate significant frustration over the inability to communicate effectively. There are 3 main methods of voice restoration: esophageal speech, usage of the electrolarynx, and tracheal-esophageal puncture for tracheal-esophageal speech, which can be performed primarily or secondarily.

Myxomas of the vocal fold are rare benign tumors often presenting with chronic dysphonia and less frequently with airway obstruction. The current consensus is that all laryngeal myxomas should be totally excised with clear margins to prevent recurrences. The recommendation for complete excision, however, has to be balanced with consideration of preserving vocal fold phonatory and sphincteric function.

A man, age 62 years, presented to the clinic with a 2-week history of increased nontender, nonerythematous, indurated right-sided parotid swelling. A 4 × 6-cm firm, well-circumscribed mass was palpated in the right parotid gland. A fine-needle aspiration biopsy was performed on the parotid mass with aspiration of 0.

Importance: Currently there are few validated metrics for predicting surgical skill among otolaryngology residency applicants.

Objective: To determine whether manual dexterity aptitude testing in the form of soap carving during otolaryngology residency interviews at Kaiser Permanente Medical Center Oakland predicts surgical skill at the time of graduation from otolaryngology residency programs.

Design, Setting, And Participants: This study was conducted to determine how applicants with the best and worst soap carvings compared at the time of graduation with respect to various metrics including visuospatial ability and manual dexterity.

A 29-year-old woman presented from another hospital with a 10-month history of an enlarging left-sided facial mass. Computed tomographic scan revealed a mass in the superficial lobe of the left parotid gland with left-sided cervical lymphadenopathy. The patient received a total left parotidectomy and a selective neck dissection.

Objectives/hypothesis: Assess whether changes in Epstein-Barr virus (EBV) serology status relates to immunohistochemical evidence of active EBV infection in tonsillar tissue of pediatric organ transplant recipients. Children who seroconvert from EBV seronegative to seropositive status following organ transplantation are more likely to develop evidence of active EBV tonsillar infection than those who do not seroconvert. Active EBV infection is a potential early precursor of post-transplantation lymphoproliferative disorder (PTLD), a life- and/or organ-threatening disease.

The ability of the transition metal complex M(salen)* (M = Ni, Cu) to form Lewis acid-base adducts with lead(II) salts has been explored. The new complexes Pb(Hsal)(2)(Cu(salen*))(2) (1), [Pb(NO(3))(Cu(salen*))(2)](NO(3)) (2), Pb(OAc)(2)(Cu(salen*)) (3), and [Pb(OAc)(Ni(salen*)(2)](OAc) (4) (Hsal = O(2)CC(6)H(4)-2-OH, salen* = bis(3-methoxy)salicylideneimine) have been synthesized and characterized spectroscopically and by single-crystal X-ray diffraction. The coordination environment of the lead in the heterobimetallic complex is sensitive both to the initial lead salt and to the transition metal salen* complex that is employed in the synthesis.
