Pediatric malignant salivary gland tumors: 60 year follow up.

Objective: To evaluate the presentation, treatments and outcomes in pediatric patients with salivary gland malignancies.

Study Design: Retrospective chart review (1950-2012), Prospective phone interview.

Methods: Patients ≤18 years old with a salivary gland malignancy treated at our institution were identified.

Level IIB lymph node metastasis in laryngeal and hypopharyngeal squamous cell carcinoma: single-institution case series and review of the literature.

Objectives/hypothesis: To determine the incidence of level IIB lymph node metastasis in patients with laryngeal or hypopharyngeal squamous cell carcinoma and to evaluate the need for elective and therapeutic neck dissection of level IIB.

Study Design: Retrospective cohort study and review of the literature.

Methods: Patients with laryngeal or hypopharyngeal squamous cell carcinoma (N = 65) were primarily treated with surgery at Mayo Clinic (Rochester, Minnesota) from 2004 through 2010.

Level IIB lymph node metastasis in oropharyngeal squamous cell carcinoma.

Objectives/hypothesis: To determine the incidence of level IIB lymph node metastasis in patients with oropharyngeal squamous cell carcinoma (OPSCC) and to evaluate the necessity of level IIB dissection for elective and therapeutic neck dissections.

Study Design: Retrospective cohort study.

Methods: Patients with OPSCC (N = 348) were surgically managed at our institution from 2004 through 2010.

Collision tumor of the facial nerve: a synchronous seventh nerve schwannoma and neurofibroma.

Objective: To report a novel case of a collision tumor involving an intraparotid neurofibroma and a mastoid segment facial nerve schwannoma.

Study Design: Clinical capsule report.

Setting: Tertiary academic referral center.

The intraparotid facial nerve schwannoma: a diagnostic and management conundrum.

Objectives: The aims of the study were (1) to review the management strategy and clinical outcomes of all intraparotid facial nerve (FN) schwannomas (PFNSs) treated at a single tertiary academic center from 1975 to 2010 and (2) to summarize all previously reported cases of PFNS in the international literature.

Study Design: A retrospective cohort study and literature review.

Methods: Fifteen patients were diagnosed and treated at the authors' institution from 1975 to 2010.

Location of bacterial biofilm in the mucus overlying the adenoid by light microscopy.

Objective: To determine the location of bacteria and biofilm in adenoid tissue and in mucus overlying the adenoid.

Design: Adenoids removed in 1 piece were oriented to the cephalic and caudal ends. Mucus was fixed by the gradual addition of Carnoy fluid.
