Surgical alternatives to uvulopalatopharyngoplasty in sleep apnea syndrome.

Uvulopalatopharyngoplasty (UPPP) is the surgery most often performed for sleep apnea syndrome (SAS). However, good results with UPPP, demonstrated by polysomnography, have been reported in only 50% of cases. Failure of UPPP may be caused by: 1) bad management of the SAS, which is better treated in some patients with nasal CPAP than with surgery; and 2) an airway obstruction located not only at the palatopharynx (PP) level. Other surgical procedures to enlarge other sites of obstruction are described. Retro-tongue-base-pharynx (RTBP) surgery is emphasized, including mandibular advancement, hyoid bone suspension, and tongue base reduction. Maxillomandibular advancement is the most efficient technique but also the most complicated.

[Obstructive dyspnea of oropharyngeal origin].

Obstructive dyspnoea of oropharyngeal origin is a recently recognized entity with numerous clinical forms depending on age, severity and symptoms. The authors insist on the two facets of this pathology that are most frequently seen and therefore of special interest to practitioners: the oropharyngeal obstructive syndrome due to enlarged tonsils in children, and the pharyngeal obstruction responsible for snoring and for the sleep apnoea syndrome in adults. In children, tonsillectomy is necessary to avoid complications which are sometimes severe. The various clinical features of snoring and sleep apnoea syndrome in adults, as well as their exploration and treatment, are described.

[Snoring and sleep apnea syndrome in the elderly].

After shorts general considerations about physiologic and epidemiologic features relative to sleep, snoring and apneas in elderly, authors bring analysis of 30 snorers over sixty years. They all had a sleep recording, a ENT examination, and a pharyngeal C.T. scan. The main results are following: the high frequency of Sleep Apnea Syndrome (SAS) over 60 is to be carefully considered. So, Sleep recording appears necessary in the main part of this population. Cardiovascular, pneumologic and neurologic disease are very often associated, and do constitute elements of therapeutic choice. Velopharyngeal narrowing, without other level of superior airway closure, is the usual case. Therapeutic management is often difficult; there is a choice, in apneic patients, between Uvulo-Palato-Pharyngoplasty (UPP), sometimes impossible because of associated pathology, and nocturnal Continuous Positive Airway Pressure (CPAP), which employment is not always easy.

[Primary cervico-facial amylosis. Apropos of a case].

Diagnosis in a case of primary localized amylosis of the sinuses and cervical nodes was from the discovery of nasal obstruction with conductive hearing loss and cervical nodes. Biopsy confirmed the presence of amyloid deposits in the maxillary sinuses mucosa and the cervical nodes. This case illustrates the value of typing of the amylosis, rectal biopsy and investigation to detect a myeloma, thus providing confirmation of a primary localized amylosis. A literature review confirmed the rarity of this localization of amyloidosis.
