RESUMO
The Nasolacrimal sac inflammation, also known as dacryocystitis, is frequently accompanied by nasolacrimal duct blockage at the confluence of lacrimal sac and duct. Treatment of choice for dacryocystitis is dacryocystorhinostomy (DCR), which can be done through external approach and endoscopic approach. The endoscopic DCR has distinct advantage over the external DCR as there is no facial scar& also it maintains the pump action. We have used flap suturing technique of endoscopic DCR in our study where in lacrimal sac medial flap is sutured to nasal mucosal lateral flap wherein patients were selected into either of the two groups such as Anterior-Posterior type (group A) and Superior-Inferior type (group B) of Flap suturing technique. Aim and objectives of the study were to compare the subjective and objective success rate between group A & B of flap suturing used in endoscopic DCR & to compare the success rate of our techniques with other techniques in literature. Our study was Duration based prospective observational study with a Duration of one year from June 2021 till June 2022 with study population comprised of patients in age group of 20 to 70 years, with complaints of watering of eye (epiphora) attended ENT Department of our institute during this one year. Study population comprised of Total of 86 patients (100 eyes) of which 45 patients (51 EYES) underwent anterior- posterior flap suturing (Group A) and 41 patients (49 eyes) underwent superior- inferior flap suturing (Group B) technique of endoscopic DCR The mean age ± standard error of mean was 45.1765 ± 1.5 and 49.0816 ± 1.9 in group A & B respectively,which was not statistically significant (p value = 0.994). The male and female patients in group A & B was 27.45%,72.54% and 34.69%,65.30% respectively which was not statistically significant (p value = 0.434). At each followup, subjective success rate was more in group A that indicated a better trend of success for that group. However, the difference in the success rate was not statistically significant.The objective success rate between the two groups were more or less similar & was not statistically significant. The subjective success rate in both Anterior-Posterior type (group A)and Superior-Inferior type (group B) of Flap suturing techniques of endoscopic dacryocystorhinostomy were more or less similar with regards to absence of epiphora but objective success rate with regards to the patency, were almost similar with a shift of trend from Group A to group B at 6 months follow up and we also found that complications in both the groups were very few, without statistically significant difference between them. In terms of success rate and complication,The endoscopic DCR with flap suturing technique found to be more or less similar with previous techniques of DCR described in the literature.
RESUMO
Dentigerous cysts involves erupted or developing teeth in decreasing order of frequency as mandibular third molars, the maxillary canines, the maxillary third molars with rare involvement of the central incisors & are usually asymptomatic but becomes symptomatic with symptoms such as swelling, mild sensitivity, tooth mobility and displacement when it reaches size > 2 cm in diameter. Dentigerous cysts are seen most commonly in 20-30 years age group with relative low frequency in children with proportion of 4-9% of these cysts occur in the first 10 years after birth. Hospital based study conducted in the Department of ENT at Ashwini Rural medical college & Hospital, Solapur in which we have reported a series of three cases of dentigerous cyst in paediatric patients. Dentigerous Cysts in our study were associated with maxillary permanent lateral incisor, mandibular permanent premolar, Mandibular second molar tooth in pediatric age group. Provisional diagnosis of Dentigerous cyst based on clinical, radiological & biochemical study but Histopathological examination confirms the diagnosis. Dental orthopentamogram aids in diagnosing and localizing the Dentigerous cyst and ct face in all views helps to see bony effects and complications due to expansion of Dentigerous cyst. Enucleation of the cystic lesion followed by extraction of the offending teeth is a suitable treatment modality for Dentigerous cyst associated with maxilla and mandible giving adequate balance between complete removal of cyst & giving chance for eruption of unerupted teeth.
