Abstract: Most instances of elongated or otherwise abnormal styloid processes that have been reported were observed by anatomists rather than by clinicians. It is probable that numerous cases of elongated styloid processes have been observed and treated by operation when necessary, but relatively few have been recorded. The credit for the first authentic report of clinical symptoms with subsequent removal of the styloid process goes to Weinlecher, for a case observed in 1872. Ossification of the stylohyoid ligament, however, had been recorded as early as 1652 by Demanchetis. The normal styloid process measures between 2.5 and 3 cm. The tip is cartilaginous and is continued over to the lesser cornu of the hyoid bone as a band known as the stylohyoid ligament. Total calcification of this ligament has been observed anatomically. According to Dwight, 1 the styloid process can be divided into four portions. The most proximal, a cuplike portion, is called
TL;DR: A detailed cephalometric analysis was conducted on lateral x-rays from 30 adult patients with obstructive sleep apnea (OSA) and 12 age and sex-matched controls.
Abstract: A detailed cephalometric analysis was conducted on lateral x-rays from 30 adult patients with obstructive sleep apnea (OSA) and 12 age- and sex-matched controls. Statistical findings show that OSA patients are different from controls in at least five ways: 1. Their tongue and soft palate are significantly enlarged. 2. The hyoid bone is displaced inferiorly. 3. The mandible is normal in size and position (no micrognathia or malocclusion), but the face is elongated by an inferior displacement of the mandibular body. 4. The maxilla is retropositioned and the hard palate elongated. 5. The nasopharynx is normal, but the oropharyngeal and hypopharyngeal airway is reduced in area by an average of 25%, a factor that could produce or enhance OSA symptoms. These data suggest that cephalometric evaluation could be useful when used with head and neck examination, polysomnographic and endoscopic studies to evaluate OSA patients, and to assist with the planning/surgical treatment for improvement of upper airway patency.
TL;DR: There is a strong evidence for reduced pharyngeal airway space, inferiorly placed hyoid bone and increased anterior facial heights in adult OSA patients compared to control subjects, which supports the relationship between craniofacial disharmony and obstructive sleep apnea.
TL;DR: In this article, a bone anchor is inserted into the mandible of a human subject, and a suture is attached to the bone anchor to suspend the tongue to the mouth.
Abstract: Methods and devices for the treatment of airway obstruction, sleep apnea and snoring, by tongue suspension for treatment of airway obstruction in a human subject, including the steps of inserting a bone anchor into the mandible of the subject, and fastening at least one suture to the bone anchor to suspend the tongue to the mandible. Preferably, the bone anchors used are surgical screws. The sutures are fastened to at least one surgical screw, and are preferably inserted in positions adjacent to the mandible's midline. Alternatively, suspension of the hyoid bone is accomplished.
TL;DR: The partial horizontal supracricoid laryngectomy with cricohyoidoepiglottopexy consists of resection of the whole thyroid cartilage and paraglottic space to treat carcinomas of the glottis that spread beyond the confines of the membranous portion of the true vocal cord or present with limitation of true vocal Cord mobility.
Abstract: The partial horizontal supracricoid laryngectomy with cricohyoidoepiglottopexy consists of resection of the whole thyroid cartilage and paraglottic space. The cricoid cartilage, the hyoid bone, most of the epiglottis, and at least one arytenoid cartilage are conserved. Thirty-six patients with squamous cell carcinoma of the glottis who underwent this procedure from 1974 through 1986 are presented. All 36 recovered physiologic deglutition and phonation. None required a permanent tracheotomy. The 3-year actuarial survival rate was 86.5%. The local recurrence rate was 5.5%. The indications for the procedure are carcinomas of the glottis that 1) spread beyond the confines of the membranous portion of the true vocal cord or 2) present with limitation of true vocal cord mobility. The procedure is presented as a useful alternative to radiotherapy, partial vertical laryngectomy, and total laryngectomy in select cases of glottic carcinoma.
