Nasolacrimal Duct Obstruction: An Unusual Presentation of Sarcoidosis.

Lacrimal drainage system disorders leading to epiphora are a common ophthalmologic complaint. When such a patient is identified, the ophthalmologist frequently collaborates with the otolaryngologist to perform a dacryocystorhinostomy (DCR). In rare cases, sinonasal sarcoidosis may lead to nasolacrimal duct obstruction (NLD) and dacryocystitis.

Breast Cancer Metastases to the Paranasal Sinuses Mimicking Inflammatory Sinus Disease.

Introduction: Breast cancer is one of the most common cancers in women. Metastatic disease is a leading cause of morbidity and mortality. It frequently metastasizes to bone, lungs, regional lymph nodes, liver and brain.

Nasal cytology with emphasis on mast cells can improve the diagnosis and treatment of chronic rhinosinusitis.

Objective: Chronic rhinosinusitis (CRS) involves inflammation of the nasal and para-nasal mucosa. Due to its heterogeneous nature, unknown pathogenesis, and high recurrence rate, effective treatment is difficult. Nasal cytology is presently not a part of the routine diagnosis or treatment decision for CRS.

CO-laser-assisted diverticulotomy remains an effective and safe method for treating Zenker diverticulum.

Our objectives were to review our experience with laser-assisted diverticulotomy (LAD) in the treatment of Zenker diverticulum (ZD) and compare our results with those in published literature on other endoscopic and surgical techniques. We conducted a retrospective chart review of 57 patients who underwent LAD treatment of ZD in a single tertiary care institution. Data on surgical complications, length of stay, and follow-up were collected.

Endoscopic Approach for Excision of Venous Malformation of the Orbital Apex.

Introduction: Venous malformation is a common tumor of the orbit, presenting with visual impairment and proptosis. These lesions can be excised via an external or transcranial approach, but recent advances in minimally invasive surgery have led to increased popularity of endoscopic approach.

Patient: The authors report a 62-year-old female presenting with diplopia and proptosis, found to have a 1.

Surgical resection of sinonasal hemangiopericytoma involving anterior skull base: Case reports and literature review.

Hemangiopericytomas are soft tissue tumors composed of pericytic cells that are characterized by their "staghorn" vascular branching and their variable clinical presentation. Fifteen to 25% of all HPC occur in the head and neck, with only 5% found in the nose or paranasal sinuses. Sinonasal hemangiopericytoma (SNHPC) is considered distinct from its soft tissue counterpart - the former showing a more uniform cellular organization, has convincing pericytic differentiation and is associated with a far better prognosis.

Schwannoma of the nasal cavity.

Schwannomas are benign peripheral nerve sheath tumors that occur throughout the body. They may present as either solitary or multiple masses. They rarely occur in the nasal cavity.

Tracheoesophageal voice restoration following laryngotracheal separation procedure.

Objectives: Laryngeal dysfunction leading to incompetence and intractable aspiration can be a life-threatening problem. Laryngotracheal separation (LTS) can be used to prevent aspiration, but results in aphonia. The options for laryngeal speech following LTS are limited.

Sinonasal facial pain.

Evaluation of the paranasal sinuses and nasal cavity in patients with headache and or facial pain must include a thorough medical and social history, with close attention to the pattern and character of the pain, a thorough physical examination that includes a palpation and nasal endoscopy, and imaging studies such as CT scans and Magnetic Resonance Imaging. The physician must remember that every pain in the face is not caused by sinusitis.

Paranasal sinus development: a radiographic study.

Objective: To demonstrate the development of the paranasal sinuses in a pediatric population by computed tomography scans.

Study Design: Radiology records at a tertiary care institution were reviewed for the computed tomography scans of the face, orbit, or paranasal sinuses in patients aged 0 to 12 years.

Methods: Computed tomography scans were reviewed by a head and neck radiologist and otolaryngologist for the development of the frontal, maxillary, ethmoid, and sphenoid sinuses.

Laser soft palate "stiffening": an alternative to uvulopalatopharyngoplasty.

Background And Objective: Habitual snoring is best treated surgically, with uvulopalatophayngoplasty, but the standard "cutting" procedure poses potential morbidity. In this study, a new approach, stiffening of the soft palate with a low energy laser, was studied as a less invasive alternative. Study Design In an in vitro study, five fresh palates of canines were used to see acute thermal effect on the palatal tissue after laser treatment.
