INTRODUCTION: Revision shoulder arthroplasty presents many unique and complex challenges when glenoid bone loss is involved. A distorted and medialized anatomy prevents the proper mechanics of the reverse prosthesis with regard to deltoid tension and ultimate function. This paper highlights one surgeon's experience using structural allograft for glenoid bone loss. PATIENTS AND METHODS: In all, 20 patients for a total of 24 surgeries with a medialized glenoid and/or substantial glenoid bone loss of grade IIB or higher were evaluated in this retrospective study...

Objectives: The resection status is one of the most important prognostic factors for patients with head and neck squamous cell carcinoma (HNSCC) concerning overall survival (OS) and recurrence free interval (RFI). To assess whether therapy concepts changed depending on different resection margins and extracapsular extension, OS and RFI data were set into clinical context. Methods: All HNSCC patients who underwent head and neck surgery with/without adjuvant therapy (n=534) were selected over a ten-year period (2001-2011)...

Objective  Treatment for head and neck paragangliomas (HNGPL) can be more harmful than the disease. After diagnosis, an initial period of surveillance is often indicated, and surgery or radiotherapy is reserved for progressive disease. With the aim to optimize this "wait and scan" strategy, we studied growth and possible predictors. Design  A retrospective cohort study was conducted. Setting  This study was conducted at a tertiary referral center for patients with HNGPL. Methods  Tumor volume was estimated for 184 SDHD -related carotid and vagal body paragangliomas using sequential magnetic resonance imaging...

OBJECTIVE: Microvascular coupler devices have been proven an effective alternative to standard hand-sutured anastomoses in reconstructive surgery. Until now, the influence of the coupler size on the revision rate after free flap tissue transfer in head and neck surgery has not been investigated. Neither has its influence on the timing of venous revisions. MATERIALS AND METHODS: A retrospective mono-center cohort study was performed in order to analyze the influence of coupler size on timing and revision rate of microvascular procedures...

Abrikossoff's tumour or granular cell tumour is a rare entity. Most common locations are the head and neck, with only a few cases reported on the upper limbs. A 55-year-old man with a nodular lesion on the left arm resorted to surgery consultation. Nodule was firm, mobile, painless and non-ulcerated. Total excision using a Limberg flap procedure was performed. Following 3 months of follow-up, the patient is fine. Abrikossoff's tumour is frequently presented in the second to sixth decade of life as an ulcerated nodule with progressive growth...

REVIEW
Rabie M Shanti, Bert W O'Malley
Today, most head and neck cancer subsites, such as the larynx, hypopharynx, nasopharynx, and oropharynx, are treated with radiation therapy with or without chemotherapy as a primary treatment modality. Surgery is reserved for the salvage of recurrent tumors that occur within the head and neck in the absence of distant (ie, lung, liver) metastasis. However, unlike all other head and neck subsites, oral cancer should ideally be managed with primary surgery with the possibility of adjuvant radiation therapy with or without chemotherapy depending on the presence of certain high-risk pathologic features...

OBJECTIVES: Defects after ablative tongue cancer surgery can be reconstructed by split-thickness skin grafts or free microvascular flaps. The different surgical options may influence costs, reimbursement, and therefore possible profits. Our goal was to analyze the development of these parameters for different procedures in head and neck reconstruction in Germany over the last decade. MATERIALS AND METHODS: After tumor resection and neck dissection of tongue cancer, three different scenarios were chosen to calculate costs, reimbursement, length of stay (LoS), and profits...

BACKGROUND: Head and neck surgery is not often considered a risk factor for intestinal ileus and small bowel obstruction. However, many of these patients may have had prior abdominal surgery, a known risk factor for small bowel obstruction, and may be at risk for bowel obstruction after a surgical procedure of the head and neck. METHODS: We present a case describing a patient who, after undergoing transoral robotic surgery, experienced delayed postoperative ileus and eventual small bowel obstruction requiring exploratory laparotomy and bowel resection...

Globus may be a persistent symptom impairing patients' quality of life. Diagnostics and treatment are controversial but some globus patients may benefit from reassurance and attention. We investigated how globus symptoms change during a short-term follow-up without any treatment after an examination by an ear, nose and throat (ENT) physician and further diagnostic procedures. We also surveyed whether patients with persistent globus suffer from simultaneous voice problems. The study comprised 30 consecutive globus patients referred to Helsinki University Hospital, Department of Otorhinolaryngology - Head and Neck Surgery...
