The perception and practice of routine lingual flap retraction in lower third molar surgery among oral and maxillofacial surgeons in Nigeria.

Background: Lingual nerve injury is a known complication of mandibular third molar (M3M) surgery, and retraction of the lingual flap is reported to reduce the incidence of this complication. However, there is no global consensus on the routine retraction of lingual flap. Aim: The aim of the study was to assess the perception and practice of lingual flap retraction amongst oral and maxillofacial surgeons in Nigeria. Materials and Methods: This cross-sectional national survey was conducted amongst 122 oral and maxillofacial surgeons in Nigeria from January 2023 to March 2023 using a validated, structured, self-administered questionnaire. The questionnaire had three sections and 14-item questions. Section A consists of the sociodemographic questions, Section B comprises questions on perception towards lingual flap retraction, whereas Section C consists of questions on the practice of lingual flap retraction. These questionnaires were deployed as an online survey and as hard copies. Both qualitative and quantitative data were analysed. A critical probability level (P < 0.05) was used as the cut-off level for statistical significance. Results: Most of the participants (47.6%) belong to the age group of 31-40 years. The male-to-female ratio was 6:1. Only 12 (9.8%) participants had a positive perception towards routine lingual flap retractions following M3M surgery. Perception of lingual flap retraction was found not to be associated with the demographic variables of the participants (P > 0.05). A total of 95 participants (77.9%) did not raise nor retract the lingual flap during lower third molar surgery. The rate of practice of lingual flap retraction during third molar surgery was not influenced by any of the factors studied (P > 0.05). Conclusion: The majority of oral and maxillofacial surgeons in Nigeria do not agree that routine retraction of the lingual flap is necessary to reduce lingual nerve injury and majority, too, do not practice this in their management of impacted lower third molar.

Patient satisfaction with intraoral examination in a Nigerian tertiary hospital

Objectives: While studies on satisfaction following medical procedures are well documented, but this is not so with dental procedures. Therefore, this study aims to determine the level of satisfaction in patient undergoing intraoral examination (IOE). Material and Methods: Consecutive patients attending the oral diagnosis clinic of University of Benin Teaching Hospital from April 2020 to September 2020 were interviewed using a questionnaire modified from the modified Group Health Association of America-9 questionnaire. Results: A total number of 103 consecutive dental patients were recruited as they all agreed to participate in the study. The age range was 18­77 years with a mean age of 35.8 ± 14.3 years. There were more males (51.5%). The overall satisfaction was 82.5%. The maximum satisfactory response was on doctor's manner (93.2%), followed by staff 's manner (89.3%), comfort during IOE (80.6%), adequate explanation (78.6%), and finally by waiting time (60.2%). There was association between occupation (P = 0.04) of the patients, type of dental condition (P = 0.03), waiting time (P = 0.01), doctor's manner (P = 0.00), staff manner (P = 0.00), adequate explanation (P = 0.00), comfort during IOE (P = 0.00), and level of satisfaction. The problem rate was 16%. Conclusion: Although waiting time and adequate explanation ranked the highest in terms of unfavorable responses, the overall satisfaction of patients following IOE was generally good. The factors that influence satisfaction were occupation of the patients, type of dental condition, waiting time, doctor's manner, staff manner, adequate explanation, and comfort during IOE.

Otitis media with effusion in Nigerian children with cleft palate: incidence and risk factors.

Otitis media with effusion is common in children with cleft palate, and the aim of this study was to find out its incidence and risk factors in Nigerians. We prospectively studied 84 patients (42 with cleft palate and 42 control subjects); 27 were male and 15 female, who were age and sex matched with control subjects. The extent and size of the clefts were measured using a dental cast and Vernier calipers, and the otitis media was diagnosed with otoscopy and tympanometry. The mean (SD) age of the groups was 11 (7) months (range 1-33). Twelve children in the cleft group had otitis media compared with three in the control group. Infants and boys were more likely to be affected. There was a significant association between age (p=0.02), sex (p=0.01), and size of cleft (p=0.00). However, only the size of the cleft was confirmed to be an independent predictor, with children who had extremely wide clefts being more likely to develop otitis media than those with narrow clefts (OR=8.71, 95%CI=1.07 to 70.5).We conclude that the incidence of otitis media with effusion was higher among children with cleft palate than among those who did not have a cleft. Infants had a higher incidence than older children, and boys had a higher incidence than girls. Age, sex, and the size of the palatal cleft were significantly associated with otitis media, but not the extent of clefting.

Hematological Indices of Patients with Retained Lead Pellets in the Craniomaxillofacial Region Following Gunshot Wounds.

BACKGROUND: Acute and chronic environmental lead exposures are associated with alteration of hematological parameters. It is not known whether retained lead pellets have similar effects on hematological variables to environmental exposures. OBJECTIVE: The objective of this study is to assess the effects of retained lead pellets on hematological indices in patients that sustained gunshot injuries to the craniomaxillofacial region. PATIENTS AND METHODS: We examined individuals with retained pellets following gunshot injuries to the craniomaxillofacial region using a prospective cohort study design in a tertiary health center, Nigeria. RESULTS: A total of 54 male individuals (27 in each group) enlisted in the study. The age of the patients and control subjects ranges from 20 to 58 years, with a mean age of 40.3 years. The mean blood lead levels (BLLs) of the exposed group were lower than the unexposed (P = 0.03). There were statistically significant (P < 0.05) variations in the hematological indices between the exposed and the unexposed groups. There was a significant association (P < 0.001) between the hematological indices assessed and the BLLs, number of retained pellets, and duration of retention. No basophilic stippling was observed in the red cell morphology of the individuals. CONCLUSION: Retained lead pellets cause significant elevated BLL and associated higher hematocrit, hemoglobin concentration, and mean cell volume.
