Sex-based outcomes in type I thyroplasty for nonparalytic glottic incompetence.

Objective: Clinical outcomes for type I Gore-Tex thyroplasty (GMT) for nonparalytic glottic incompetence (GI) have been reported in the literature. Given differences in male and female laryngeal anatomy, sex-based outcomes should also be evaluated. We endeavored to evaluate sex-specific post-GMT voice outcomes.

Analysis of anterior and posterior maneuvers to enhance intraconal exposure.

Background: The medial and inferior recti encompass the ideal surgical corridor to approach the intraconal space endonasally. Here, we describe 3 different maneuvers to achieve greater access to orbital contents through an expanded endonasal approach (EEA).

Methods: Four human cadaver heads were dissected bilaterally (n = 8).

Conscious Perception of Facial Asymmetry in a Unilateral Cleft Lip Model.

Objective: Lip asymmetry after a unilateral cleft lip repair can be perceived as an unsatisfactory result. The objective of this study is to determine the degree of upper lip asymmetry and/or nasal alar hooding required for recognition of asymmetry in a simulated model of unilateral cleft lip.

Design: A model of unilateral cleft lip was created using digital morphing software to simulate asymmetries in vermilion height and nasal hooding in photographs of children.

Hypovolemic shock after labial and lingual frenulectomy: A report of two cases.

Lingual and labial frenulectomy are commonly performed as an outpatient procedure, either in an office setting or under general anesthesia. Frenulectomy is generally regarded by both otolaryngologists and dentists as a straightforward and low-risk procedure with limited evidence-based indications and similarly few contraindications. We describe two cases of hypovolemic shock occurring after outpatient frenulectomy requiring emergent interventions of cardiopulmonary resuscitation and blood transfusion.

Carotid artery and lower cranial nerve exposure with increasing surgical complexity to the parapharyngeal space.

Objectives/hypothesis: To investigate the extent of carotid artery exposure attained, including the identification of the external carotid branches and lower cranial nerves in five sequential external approaches to the parapharyngeal space, and to provide an anatomical algorithm.

Study Design: Anatomical study.

Methods: Six latex-injected adult cadaver heads were dissected in five consecutive approaches: transcervical approach with submandibular gland removal, posterior extension of the transcervical approach, transcervical approach with parotidectomy, parotidectomy with lateral mandibulotomy, and parotidectomy with mandibulectomy.

The Reverse-Flow Facial Artery Buccinator Flap for Skull Base Reconstruction: Key Anatomical and Technical Considerations.

Objective To highlight key anatomical and technical considerations for facial artery identification, and harvest and transposition of the facial artery buccinator (FAB) flap to facilitate its future use in anterior skull base reconstruction. Only a few studies have evaluated the reverse-flow FAB flap for skull base defects. Design Eight FAB flaps were raised in four cadaveric heads and divided into thirds; the facial artery's course at the superior and inferior borders of the flap was measured noting in which incisional third of the flap it laid.

Differences in skull base thickness in patients with spontaneous cerebrospinal fluid leaks.

Background: This study was designed to determine if differences in overall skull base thickness exist in patients with spontaneous cerebrospinal fluid (SCSF) leaks and to compare our institution's 10-year experience with the endoscopic repair of these leaks to the existing literature. A retrospective cohort study was performed in a tertiary rhinologic practice.

Methods: A retrospective study by two blinded independent reviewers compared the skull base thickness on computerized tomography (CT) imaging in our SCSF leak patients to nonleaking controls and patients with traumatic CSF leaks.

Sources and structures of mitotic crossovers that arise when BLM helicase is absent in Drosophila.

The Bloom syndrome helicase, BLM, has numerous functions that prevent mitotic crossovers. We used unique features of Drosophila melanogaster to investigate origins and properties of mitotic crossovers that occur when BLM is absent. Induction of lesions that block replication forks increased crossover frequencies, consistent with functions for BLM in responding to fork blockage.

Squamous cell carcinoma of the uvula: an analysis of factors affecting survival.

Objectives/hypothesis: Uvular squamous cell carcinoma (SCC) is usually considered with soft palate tumors as an oropharyngeal cancer subsite. This investigation aims to determine whether the uvula itself is a high-risk subsite in the oropharynx for primary squamous cell carcinomas.

Study Design: Retrospective analysis of a large population database.

Salivary morbidity and quality of life following radioactive iodine for well-differentiated thyroid cancer.

Objective: Determine the prevalence of sialadenitis in a group of patients treated with radioactive iodine (RAI) for well-differentiated thyroid cancer and assess whether RAI treatment is associated with a reduction in swallowing-related or global head and neck quality of life.

Study Design: Retrospective self-administered questionnaire study.

Setting: Academic, tertiary care, National Cancer Institute-designated cancer center.

Head and neck soft tissue sarcomas: unique lack of significance of synchronous node metastases.

Background: Regional lymph node metastasis (RLNM) has been identified as a poor prognostic indicator for patients with soft tissue sarcomas (STS) of the extremities and trunk. However, the effect of RLNM on survival in patients with STS of the head and neck (HN) has not previously been explored. Our objective was to analyze RLNM as a prognostic indicator in HN-STS, and to compare this cohort to patients with STS of non-head and neck regions (NHN-STS).

Rosai Dorfman Disease presenting as unilateral chronic parotitis.

We report a 48-year-old man who presents with a 20-month history of left parotid enlargement despite treatment with antibiotics and steroids. He presented with a non-painful palpable mass in his left parotid without facial weakness or otologic symptoms. Fine needle aspiration was inconclusive, and an attempted excisional biopsy was aborted due to involvement of the facial nerve and suspicion of lymphoma.
