Epiglottis prolapse during inspiration is an unusual cause of upper airway obstruction. It occurs primarily in patients who have lost pharyngeal airway support because of previous surgery or after head injury and coma. Eight cases of epiglottis prolapse are presented. One patient had epiglottis prolapse after resection of floor of mouth cancer and another after laryngeal fracture. The rest of the cases were seen in patients recovering from head injury and coma. Videolaryngoscopy shows the larynx to assume an ovoid shape within the pharynx. There is loss of the usual anterior to posterior pharyngeal and laryngeal dimension. The epiglottis is in a more horizontal position at rest. During inspiration, the epiglottis prolapses into the endolarynx, causing subtotal airway obstruction. Laryngeal obstruction due to epiglottis prolapse can prevent decannulation in the head-injured and can be the cause of obstructive sleep apnea. Endoscopic carbon dioxide laser epiglottectomy was successful in management of these cases.

Two patients are discussed in whom obstructive sleep apnea was precipitated by uvular prolapse into the larynx and successfully treated by uvulopalatopharyngoplasty. Although tracheostomy has been the definitive treatment for obstructive sleep apnea, uvulopalatopharyngoplasty has also been used as an alternative surgical procedure. However, indications for its successful use have not been clearly defined. Our experience illustrates that the surgical approach to obstructive sleep apnea is dependent on a thorough diagnostic evaluation that includes a sleep history, head and neck examination, hypnopolygraphic recording and, if indicated, nocturnal fiberoptic endoscopy.

Floppy eyelid syndrome (FES) usually affects middle-aged obese men, presenting as a unilateral or bilateral chronic papillary conjunctivitis. The upper eyelid is lax, floppy, and easily everted. The laterality corresponds to the side the patient sleeps on. An association with obstructive sleep apnea (OSA) has been suggested. A personal series of 17 new cases is presented, and 79 previously reported cases are reviewed to give a detailed description of the syndrome. In addition to the classical presentation, patients may present with upper lid ptosis, lash ptosis or trichiasis, lower lid ectropion or rarely entropion, or corneal complications. Eight patients with FES were investigated for OSA. Twenty other patients with known OSA were examined for FES and other possibly associated ocular features. All eight patients referred for sleep studies were found to have OSA. One of the 20 patients with known OSA was found to have FES, and two had features of early asymptomatic FES. One patient with FES and OSA had normal tension glaucoma. Patients with FES should be considered for sleep studies because of the known morbidity of OSA. Simple screening of patients with OSA may detect FES and avoid late corneal complications that can compromise vision.

Obstructive sleep apnoea syndrome (OSAS) is caused by obstruction or narrowing of the airway at various levels. The repair of one site only will not alleviate the syndrome if there are obstructions in other sites. Epiglottis prolapse during inspiration is an unusual cause of airway obstruction and a rare cause of OSA. Twelve cases of OSAS due to an abnormal epiglottis are presented. We present our approach to the diagnosis using fibre-optic examination of the hypopharynx, and our treatment using endoscopic carbon dioxide laser partial epiglottidectomy. We found in our series that in 11.5 per cent of patients who failed the uvulopalatopharyngoplasty procedure, the reason was a narrow airway at the hypopharyngeal level caused by an abnormal epiglottis. It is our suggestion that in these cases a laser partial epiglottidectomy should be performed. The results of this study show that partial epiglottidectomy can increase the cure rate of patients with obstructive sleep apnoea syndrome by 10-15 per cent.

We report a 75-year-old Spanish-American woman who received a diagnosis of oculopharyngeal muscular dystrophy after presenting with ptosis and dysphagia. She also complained of snoring and daytime somnolence, and was found to have obstructive sleep apnea (OSA) syndrome attributable to her neuromuscular disorder. This is the first report of OSA syndrome complicating typical, adult-onset oculopharyngeal muscular dystrophy, and should prompt the evaluation of other such patients for sleep-disordered breathing.

Laryngomalacia occurs in some brain injury patients secondary to global muscle hypotonia. Surgical therapies for epiglottis prolapse have centered around removal or reshaping of the epiglottis. This approach has brought mixed success and frequent complications. We present a case that demonstrates successful nonsurgical treatment of a 33-year-old male brain injury patient with moderate obstructive sleep apnea that is believed to be a consequence of post-brain injury nocturnal epiglottis prolapse. The presence of a tracheostomy performed at the time of emergency surgery had become an emotional and physical barrier to our patient's recovery. The tracheostomy could only be reversed if the obstructive sleep apnea disorder could be managed in an alternative fashion. A titratable mandibular repositioning appliance was prescribed and its effectiveness was demonstrated with nasolaryngoscopy and polysomnography. After initially fitting the oral appliance, a period of accommodation and gradual protrusive adjustments was allowed. Subsequent confirmation polysomnography demonstrated improvement, but not suitable resolution, of disordered breathing events. However, an additional 1.25-mm protrusive titration of the oral appliance during the course of the confirmation polysomnogram led to therapeutic success. The patient's tracheostomy was subsequently reversed with significant quality of life benefits.

We report on a 3-year-old girl with Michels syndrome, a rare condition characterized by craniosynostosis, blepharophimosis, ptosis, epicanthus inversus, cleft lip/palate, abnormal supra-umbilical abdominal wall, and mental deficiency. The phenotypic findings are compared with the six previously reported Michels cases, and with patients referred to as Carnevale, OSA, and Malpuech syndromes. Michels syndrome is characterized by cleft lip and palate, anterior chamber anomalies, blepharophimosis, epicanthus inversus, and craniosynostosis. Carnevale syndrome shows hypertelorism, downslanting palpebral fissures, ptosis, strabismus synophrys, large and fleshy ears, and lozenge-shaped diastasis around the umbilicus. OSA syndrome resembles Carnevale, with humeroradial synostoses, and spinal anomalies as extra features. Malpuech syndrome shows IUGR, hypertelorism, cleft lip and palate, micropenis, hypospadias, renal anomalies, and caudal appendage. All are autosomal recessive. Despite the presence of apparently distinctive key features, it appears that these four entities share multiple similarities in the facial Gestalt and the pattern of MCA. Those similarities lead us to postulate that they belong to the same spectrum, which could be referred to as "3MC syndrome" (Malpuech-Michels-Mingarelli-Carnevale syndrome).

A group of syndromes, consisting of Malpuech syndrome, Michels syndrome, Carnevale syndrome, OSA syndrome, and Mingarelli syndrome share the combination of symptoms of highly arched eyebrows, ptosis, and hypertelorism, and vary in other symptoms such as asymmetry of the skull, eyelid, and anterior chamber anomalies, clefting of lip and palate, umbilical anomalies, and growth and cognitive development. It has been suggested that they are in fact part of the same entity. Here, we describe a brother and sister with the same constellation of symptoms, and compare these with the various entities. We conclude that the present patients resemble most patients with Carnevale and Mingarelli syndrome, and the case reported by Guion-Almeida, and that these patients form together most probably the same entity. We suggest the name Carnevale syndrome as this author described this combination of symptoms for the first time. Malpuech and Michels syndromes are probably separate entities, although they may still be allelic. Pattern of inheritance of Carnevale syndrome is most likely autosomal recessive.

We are using percutaneous electrical stimulation to simulate BION activation of posterior genioglossus during sleep to prevent occurrences of obstructive sleep apnea (OSA). Patients with OSA due to tongue prolapse are recruited in this ongoing clinical study for an overnight session in a sleep laboratory. Bipolar hooked wires are inserted percutaneously into the tongue muscle, from under the chin at midline, and used for neuromuscular stimulation. Data are collected with polysomnography and analyzed to compare the efficacy of proposed treatment to conventional CPAP or the untreated state. Encouraging preliminary results from the first study participant are described.

Laryngomalacia (LRM), is the most common laryngeal abnormality of the newborn, caused by a long curled epiglottis, which prolapses posteriorly. Epiglottis prolapse during inspiration (acquired laryngomalacia) is an unusual cause of airway obstruction and a rare cause of obstructive sleep apnea syndrome (OSAS). We present a minimally invasive technique where epiglottis on cadaveric larynx specimens was treated with CO2 laser. The cartilage reshaping effect induced by laser irradiation was capable of exposing the glottis opening widely. This technique could be used in selected cases of LRM and OSAS due to epiglottis prolapse as an alternative, less morbid approach.
