Postoperative microstructural re-modelling and functional outcomes in idiopathic full thickness macular hole

Purpose: To analyze the effect of various macular hole indices and postoperative microstructural changes of all retinal layers on postoperative functional outcomes in patients with idiopathic full?thickness macular hole (FTMH). Methods: In this prospective study, pre and post?operative optical coherence tomography (OCT) scans of 36 eyes with idiopathic FTMH were analyzed. Hole indices and microstructural changes of all retinal layers such as ellipsoid zone (EZ), external limiting membrane (ELM) integrity, outer and inner retinal defects, and cystoid resolution were studied on follow?up visits. Results: Out of 36 eyes, type?1 closure was achieved in 23 eyes (65.7%) and type?2 closure in 11 eyes (31.42%), one eye showed persistent hole, and one eye was lost to follow?up. The mean minimum diameter of hole (P = 0.026), mean MHI (P = 0.001), DHI (P = 0.158), THI (P = 0.001), and HFF (P < 0.001) showed statistical significance with the type of hole closure. Postoperatively, eyes with intact ELM and EZ had better BCVA at the final visit. The BCVA was better by logMAR 0.73 ± 0.38 (P < 0.001) in patients with absent outer retinal defects. There was a significant difference in BCVA of 0.52 ± 0.35 at 1 month and 0.64 ± 0.34 at 6 months in eyes without inner retinal defects (P < 0.001). At 6 months, cystoid resolution was observed in 28 (80%) eyes. BCVA was significantly better at 1 month (P < 0.001) and at 6 months (P = 0.001) in eyes with no DONFL. Conclusion: Macular hole indices determine the closure type. Postoperative regeneration of outer retinal layers and resolution of retinal defects significantly influence the final visual outcomes. ELM recovery is seen as a prerequisite for EZ regeneration with no new IRD after a period of 3 months

Assessment of intraoperative risk factors for surgical difficulty in surgical extraction of impacted mandibular third molar: a prospective study

The extraction of impacted third molars is among the most common surgical procedures carried out in the field of Oral and Maxillofacial Surgery. For proper planning of surgical extraction, espe-cially for impacted mandibular third molars the estimated level of surgical difficulty of the case is important. This study was conducted to evaluate the intraoperative risk factors contributing to surgical difficulty in extraction of impacted mandibular third molars and consequently the post-operative outcome. Here, we have undertaken a study in which the intraoperative variables were considered, to evaluate their contribution for surgical difficulty and postoperative complica-tions in surgical removal of 100 impacted mandibular third molars. Three variables were found significant associated with total surgical time intervention, i.e., surgeon's experience (p=0.006), Inter-incisal opening (p=0.032), and cheek flexibility (p=0.004). Total surgical time intervention for 'right side' was higher with 49.20 ± 17.94 minutes (p=0.691). Total surgical time intervention for 'gagging reflex present' was 50.21 ± 17.812 (p=0.674). Multiple linear regression shows that surgeon's experience was the only predictor (p<0.001). The surgical difficulty of impacted mandibular third molar are likely to depend on the intraoperative factors like Surgeon's time, surgeon's experience, check flexibility, and inter incisal mouth opening.

Evaluation of demographic and radiological risk factors for assessment of difficulty in surgical removal of impacted mandibular third molar: a prospective study

The extraction of impacted third molars is among the most common surgical procedures carried out in the field of Oral and Maxillofacial Surgery. Both the patient and dentist must therefore have scientific evidence-based information concerning the estimated level of surgical difficulty of every case to consider in referring cases of impacted third molars for specialists' handling. We have undertaken a study in which demographic and radiological variables were considered to-gether to evaluate the risk factors for surgical difficulty in a cohort of 100 impacted mandibular third molars. There were 13 variables evaluated for surgical difficulty. Total surgical time interven-tion was noted at the end of each surgery. Each variable was analysed with total surgical time intervention with univariate and multiple linear regression. Out of 13 variables, 9 were found sta-tistically significant. The most significant predictors for surgical difficulty were Body Mass Index, Depth of impacted tooth and Retromolar space. No postoperative complications were reported.

Gigantic reactive lesion of mandibular gingival tissue / Lesión gigante reactiva del tejido gengival mandibula

Irritation fibroma are the most common form of reactive lesions found within the oralcavity. These lesions normally attain a small size and show a slow growth rate. This paper reports a case ofgigantic intraoral irritational fibroma with a history of rapid growth. Complete excision was performed andthe specimen was sent for immunohistochemistry (IHC) staining. It was found positive for vimentin, hencereported as irritation fibroma.

Los fibromas irritativos son las forma más común de lesiones reactivas encontradas en la cavidad oral. Estas lesiones normalmente son de pequeño tamaño y muestran una tasa de crecimiento lenta. Este artículo reporta el caso de un fibroma irritativo gigante intraoral con historia de crecimiento rápido. Se realizó la extirpación completa y fue enviado para análisis inmunohistoquímico. Arrojó positivo para Vimentina, por lo tanto, se reportó como fibroma irritativo.

Multiple unerupted impacted supernumerary teeth: a rare case report of father and son / Múltiples dientes supernumerarios impactados no erupcionados: presentación de un caso raro de padre e hijo

Multiple impacted supernumerary teeth without any associated systemic conditions or syndromes are rare. The prevalence rate of supernumerary teeth in the permanent dentition is between 0.1– 6.9 percent as compared to 0.3–0.6 percent in theprimary dentition. In this article, reporting a rare family history of non-syndromic multiple impacted supernumerary teeth,found incidentally during routine radiographic examination. Though the etiologic factor of multiple impacted supernumerary teeth are still not clearly known especially in cases without any syndrome. However, thorough evaluation is necessary toexclude associated systemic conditions.

Son raros los casos de sujetos con múltiples dientes supernumerarios impactados sin ningún tipo de afectación sistémica o síndrome. La tasa de prevalencia de dientes supernumerarios en la dentición permanente varía entre 0,1­6,9 % en comparación con el 0,3­0,6 % en la dentición primaria. En este artículo, se reporta una historia familiar rara de múltiples dientes supernumerarios impactados no sindrómicos, encontrados incidentalmente durante un examen radiográfico de rutina. El factor etiológico de dientes múltiples supernumerarios impactados aún no está claro, especialmente en los casos sin ningún tipo de síndrome. Sin embargo, es necesaria una evaluación a fondo para descartar enfermedades sistémicas asociadas.
