ABSTRACT
AIM: Though many studies have examined cysts of the jaws, most of them focused on a group of cysts and only few have examined cysts based on a particular classification. The aim of this study is to review cysts of the oro-facial region seen at a tertiary health centre in Ibadan and to categorize these cases based on Lucas, Killey and Kay and WHO classifications. MATERIALS AND METHODS: All histologically diagnosed oro-facial cysts were retrieved from the oral pathology archives. Information concerning cyst type, topography, age at time of diagnosis and gender of patients was gathered. Data obtained was analyzed with the SPSS 18.0.1 version software. RESULTS: A total of 92 histologically diagnosed oro-facial cysts comprising 60 (65.2%) males and 32 (34.8%) females were seen. The age range was 4 to 73 years with a mean age of 27.99 ± 15.26 years. The peak incidence was in the third decade. The mandible/ maxilla ratio was 1.5:1. Apical periodontal was the most common type of cyst accounting for 50% (n = 46) of total cysts observed. Using the WHO classification, cysts of the soft tissues of head, face and neck were overwhelmingly more common in males than females with a ratio of 14:3, while non-epithelial cysts occurred at a 3:1 male/female ratio. CONCLUSION: This study showed similar findings in regard to type, site and age incidence of oro-facial cysts compared to previous studies and also showed that the WHO classification protocol was the most comprehensive classification method for oro-facial cysts.
ABSTRACT
Background: The discrepancy in diameters of the resected ends coupled with the heavy faecal loads in the colon of chronically constipated children with Hirschsprung's disease makes definitive primary pull-through procedure quite difficulty in this group. Patients and Methods: Four consecutive patients (aged 5 months to 11 years) who presented with chronic constipation were given warm saline enema along with Castor oil per oram twice daily for 1 week before and 2 weeks after full-thickness biopsies that confirmed Hirschsprung's disease. All patients had intravenous Cefuroxime or Ceftriaxone plus Metronidazole at induction of anaesthesia. Intra-operatively; the levels of resections were 6-8 cm proximal to the most contractile part of the colon adjacent to the transition zone observed after complete division of mesenteric vessels. Results: There were three males and one female; aged 5 months to 11 years. The levels of aganglionosis were in the rectosigmoid region; except one in the descending colon. There was one case each of anastomotic stenoses; mild enterocolitis and deep peri-anal excoriation. The bowel motions were two to four times daily within 1 month post-operatively. Conclusion: It can be concluded from this preliminary study that with pre-operative saline enema and oral Castor oil for about 3 weeks in chronically constipated children with Hirschsprung's disease primary pull-through procedures can be performed successfully. However; further prospective work is required with this method
