Haemangioma of the uvula causing loud habitual snoring--a rare entity.
(33/70)
Mucosal haemangiomas are unusual and typically involve frequently traumatised areas such as the lip, buccal mucosa and lateral borders of the tongue. Uvular haemangioma is rare and to our knowledge, has never been reported to cause obstructive sleep apnoea (OSA). We report an unusual case of uvular haemangioma causing loud habitual snoring and symptoms suggestive of OSA. This case report illustrates a rare cause of OSA and demonstrates the efficacy of surgery for obvious obstructive lesions of the pharynx. (+info)
Imaging findings of chronic subluxation of the os odontoideum and cervical myelopathy in a child with Beare-Stevenson cutis gyrata syndrome after surgery to the head and neck.
(34/70)
INTRODUCTION: Although uncommon, fractures of the os odontoideum are known to occur in children under 7 years old, following acute trauma. CLINICAL PICTURE: We report a case of chronic subluxation of the os odontoideum resulting in cervical myelopathy in a child with Beare-Stevenson cutis gyrata syndrome after surgery to the head and neck. TREATMENT AND OUTCOME: The patient was initially put in a Halo vest, following which occipital cervical fusion was performed. CONCLUSION: Subluxations and fractures at the odontoid synchondrosis are rare but should be anticipated in young children with risk factors for instability of the cervical spine. (+info)
Edema of the uvula: etiology, risk factors, diagnosis, and treatment.
(35/70)
Edema of the uvula (EU) is a rare occurrence sometimes associated with angioedema, urticaria, and anaphylaxis. We analyze the causes, predisposing factors, and characteristics of EU in a group of 58 patients with a mean (SD) age of 48.2 (15.2) years over the course of a year. Of the 58 patients studied, 49 (84.5%) were male and 44 (75.9%) presented isolated EU. Thirty-two patients (55.1%) with no clear etiology were classed as idiopathic. Snoring and a high body mass index were more prevalent in these patients. A variety of probable causes were identified in 26 patients (44.9%). In this group, EU was usually accompanied by urticaria, angioedema, and anaphylaxis and there was also a greater prevalence of atopy. We found that EU was idiopathic in just over half of the patients studied and that the predisposing factors were being overweight and having a tendency to snore. Patients with EU should be tested for allergies to drugs, airborne allergens, and food. (+info)
Mouth opening during sleep may be a critical predictor of surgical outcome after uvulopalatopharyngoplasty for obstructive sleep apnea.
(36/70)
STUDY OBJECTIVES: To evaluate the value of mouth opening during sleep for predicting surgical outcomes after uvulopalatopharyngoplasty (UPPP). METHODS: Retrospectively, 69 out of 120 consecutive patients with obstructive sleep apnea who underwent uvulopalatopharyngoplasty at an academic tertiary referral center were included in this study. Sixty-nine subjects underwent cephalometry, nocturnal polysomnography and sleep videofluoroscopy before and after UPPP. Multiple parameters from the above studies were evaluated as potential predictors of UPPP outcomes. RESULTS: Multivariate analysis showed that an increased angle of mouth opening during sleep was the only significant predictor for surgical failure (p < 0.001). The angle of mouth opening could predict surgical outcome with predictive values of 72.4% and 82.5% for success and failure, respectively. CONCLUSIONS: Sleep videofluoroscopy during sleep revealed that the simple measurement of mouth-opening angle could outstandingly predict surgical outcome. (+info)
