Objective: Due to the complexity of obstructive sleep apnea syndrome (OSAS), engaging patients in the right treatment poses a constant challenge. A novel oral pressure therapy device, the intermittent negative air pressure Sleep Therapy System (iNAP), has proven to ameliorate respiratory events for OSAS patients. However, the mode of action and the characteristics of its responders are not yet fully understood. Read More

Background: Nasopharyngoscopy is a common method to evaluate velopharyngeal closure in patients with cleft palate. However, insertion of a fiberoptic nasopharyngoscope causes discomfort in patients. The aim of this study was to estimate the reliability of short-time exposure images obtained using 320-row area detector computed tomography (320-ADCT) as a novel evaluation method for the assessment of velopharyngeal function.

Purpose Of Review: The purpose of this manuscript is to highlight the latest advances in diagnosis and management of velopharyngeal incompetence (VPI) as it pertains to swallowing deficits in children. This is timely and relevant as otolaryngologists are often amongst the first to diagnose and treat VPI. Although nasal regurgitation of a bolus is frequently transient, persistent problems can be associated with other swallowing problems and other significant medical problems. Read More

Background: Infants and children with syndromic craniosynostosis (SCS), such as Apert-, Crouzon- or Pfeiffer syndrome, are prone to sleep disordered breathing (SDB) including obstructive sleep apnea and upper airway resistance syndrome (OSAS, UARS), potentially leading to tracheostomy. We modified the Tübingen Palatal Plate (TPP), an oral appliance with a velar extension effectively treating airway obstruction in Robin sequence, by attaching a tube to its velar extension to bridge the narrow pharyngeal airway in SCS patients. Here, we evaluated this treatment concept. Read More

We report a case of low-grade nasopharyngeal papillary adenocarcinoma in a 9 year-old male that was diagnosed incidentally after an adenoidectomy procedure and treated with endonasal endoscopic nasopharyngectomy without any adjuvant therapy. The patient has been followed up for 3 years with no evidence of recurrence. We point out the importance of preoperative fiberoptic nasopharyngoscopy in the absence of longstanding symptoms in school-aged children and histopathologic examination of adenoidectomy specimens in the presence of atypical findings.

BACKGROUND Pleomorphic adenoma is the most common benign tumor arising in the salivary gland. The signs and symptoms of pleomorphic adenoma of the minor salivary glands vary, depending on the anatomical site involved. A rare case of pleomorphic adenoma of the posterior surface of the soft palate is reported that caused sleep disturbance, which was resolved with endoscopic surgical treatment. Read More

Background: Infants with Robin sequence (RS) suffer from upper airway obstruction (UAO) and feeding problems. We developed an oral appliance with a velar extension in combination with functional treatment and appropriate feeding techniques, which was proven effective in isolated RS. As the above problems are particularly challenging in syndromic RS, we set out to evaluate our treatment concept also in these patients. Read More

A 62-year-old man with a left temporal lobe tumor was scheduled for a semiurgent craniotomy for tumor excision. Previously, the patient had a laryngeal carcinoma that was resected and treated with chemotherapy and radiotherapy and a history of laryngeal biopsy with awake fiberoptic intubation. Because a difficult airway was anticipated, awake fiberoptic nasopharyngoscopy of the airway was performed under topical anesthesia in the operating room. Read More

The aim of the present study was to investigate if any of the three awake procedures [fiberoptic nasopharyngoscopy with modified Müller Maneuver (FNMM), nasal snoring endoscopy (NSE), or oral snoring endoscopy (OSE)] could efficiently predict the grade or pattern of upper airway (UA) collapse found with drug-induced sleep endoscopy (DISE), which is considered by many authors as the current gold standard in optimizing obstructive sleep apnea syndrome (OSAS) patient selection for UA surgery. Twenty consecutive patients (simple snorers and OSAS patients) were studied with FNMM, NSE, OSE, and DISE. The inter-test agreement was evaluated with Cohen's kappa coefficient (κ). Read More

Objective: The aim of this study was to examine the correlation between the degree or shape of pharyngeal narrowing as observed during the Muller maneuver and the severity of sleep-disordered breathing (SDB).

Subjects And Methods: We enrolled 33 patients with SDB, and they underwent polysomnography (PSG).

Stanford Sleep Disorders Clinic and Research Center, 401 Quarry Road, Stanford, CA 94305, USA.

Obstructive sleep apnea (OSA) is the result of upper airway obstruction during sleep. Hypopharyngeal airway obstruction can be caused by the prominence or relaxation of the base of the tongue, lateral pharyngeal wall, and occasionally, the aryepiglottic folds or epiglottis. Although nasal continuous positive airway pressure (CPAP) is considered as the first treatment for obstructive sleep apnea, surgery has been shown to be a viable option for patients who are intolerant of positive pressure therapy.

Objectives/hypothesis: Open-mouth breathing during sleep may increase the severity of obstructive sleep apnea (OSA) and complicate nasal continuous positive airway pressure (CPAP) therapy in patients with OSA. The aim of this study was to assess the effect of open-mouth breathing on upper airway anatomy using lateral cephalometry and fiberoptic nasopharyngoscopy.

Study Design: This was a cross-sectional study. Read More

Despite advances in positive pressure therapy for obstructive sleep apnea, compliance continues to be a problem for many patients. Sleep apnea surgery is a viable option for patients who are intolerant of positive pressure therapy. This review presents the current state of the art in sleep apnea surgery, including airway evaluation with fiberoptic nasopharyngoscopy and lateral cephalometric radiography, formulation of a surgical plan with selection of procedures to address specific sites of obstruction, as well as discussion of published surgical outcomes.
