Treatment of oral mucocele-scalpel versus CO2 laser.
(20/104)
OBJECTIVE: To compare the results obtained after oral mucocele resection with the scalpel versus the CO2 laser, based on the complications and recurrences after surgery. PATIENTS AND METHODS: Of the 68 patients we studied who have mucocele, 38 were resected with a scalpel and the remaining 30 with the CO2 laser (5-7 W). Patient sex and age were documented, along with location of the lesion as well as size, symptoms, duration, etiological factors, type of treatment, complications and recurrences after surgical removal. RESULTS: The sample comprised 40 males and 28 females, aged between 6-65 years. The histological diagnosis was extravasation mucocele in 95% of the cases. The most frequent location was the lower lip (73.5%). The mean lesion diameter was 9 mm, and in most cases no evident etiological factor was recorded. The mean duration of the lesion was 4 months. Among the cases of conventional surgical removal of mucocele, recurrence was recorded in 8.8% of the cases, and 13.2% of the patients suffered postoperative complications--the most frequent being the presence of fibrous scars. There were no complications or relapses after a minimum follow-up of 12 months in the cases subjected to CO2 laser treatment. CONCLUSIONS: Oral mucocele ablation with the CO2 laser offers more predictable results and fewer complications and recurrences than conventional resection with the scalpel. (+info)
A case of polypoidal choroidal vasculopathy. Periphery is equally important for such patients.
(21/104)
BACKGROUND: To report a case of peripheral polypoidal choroidal vasculopathy (PCV) which was treated successfully. METHODS: Interventional case report. Best-corrected visual acuity measurements (BCVA), slit-lamp examination, fundus biomicroscopy, fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were performed at baseline examination and during the follow-up period. The patient underwent ICGA-guided argon laser to treat the active polyps. RESULTS: An 82-year-old Caucasian man presented complaining of sudden deterioration of peripheral vision in his left eye (LE). His previous ocular history was associated with advanced age-related macular degeneration (AMD) involving both eyes (BE). Fundus examination revealed macular scars in BE and a large hemorrhagic pigment epithelial detachment (PED) temporal to the macula in the LE. ICGA revealed active polyps at the margins of the PED. The patient underwent ICGA-guided argon laser to treat the active polyps. Six months post-laser, the patient regained his peripheral vision with resolution of the hemorrhagic PED and remains stable until now, one year after treatment. CONCLUSIONS: Appropriate treatment and regular follow-up is important in patients with PCV and peripheral lesions even if central vision is lost. (+info)
Haemangioma of the uvula causing loud habitual snoring--a rare entity.
(22/104)
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)
