Surgical procedure and treatment results of pharyngoplasty CWICKs for obstructive sleep apnea.

Objective: Uvulopalatopharyngoplasty (UPPP) is performed as a surgical treatment at the oropharyngeal level for obstructive sleep apnea, but there are problems with variations in treatment effects and postoperative complications. Therefore, to improve those, we have devised and put into practice the so-called CWICKs, which is a modified version of barbed reposition pharyngoplasty as a surgical method. We outline the procedure of CWICKs and report the treatment results in comparison with the conventional UPPP.

[A Case of a Nasopharyngeal Chondroma Originating from the Eustacian Tube].

Chondroma of the head and neck are commonly found in the nasal cavity, paranasal sinus, or larynx but rarely at other sites. Here we report a rare case of nasopharyngeal chondroma arising from the Eustacian tube. The patient was a 55-year-old male with chief complaints of nasal obstruction and left ear fullness.

Withdrawal of Continuous Positive Airway Pressure Therapy after Malar Advancement and Le Fort II Distraction in a Case of Apert Syndrome with Obstructive Sleep Apnea.

Apert syndrome is a congenital syndrome characterized by craniosynostosis and craniofacial dysostosis, among other features, and is reported to cause obstructive sleep apnea (OSA) because of upper airway narrowing associated with midfacial dysplasia. We recently encountered a case involving a patient with Apert syndrome complicated by OSA who began to receive continuous positive airway pressure (CPAP) therapy at the age of 4. OSA resolved after maxillofacial surgery performed at the age of 11, and CPAP was eventually withdrawn.

Phase of nasal cycle during sleep tends to be associated with sleep stage.

Background And Objectives: The phenomena of periodic cycles of vascular engorgement on the nasal cavity mucosa that alternate between right and left sides are termed the "nasal cycle." The physiologic mechanisms underlying this cycle have not been entirely clarified, even more so during sleep. In this study, we measured the periodic patterns of the normal nasal cycle, not only during wakefulness but also during sleep.

Acinic cell carcinoma of minor salivary gland of the base of tongue that required reconstructive surgery.

Acinic cell carcinoma of minor salivary gland of the base of tongue is very rare. Squamous cell carcinoma is the most common tumor in the base of tongue. We present a patient with gigantic acinic cell carcinoma of the base of tongue.
