A Study to Evaluate the Efficacy of Ultrasonography as a Diagnostic Screening Tool in Maxillofacial Fractures: A Prospective Study

AIM

The aim of the study was to estimate the diagnostic efficacy of high-resolution ultrasonography (USG) in the diagnosis of maxillofacial fractures.

MATERIALS AND METHODS

A descriptive diagnostic evaluation study was carried out on 30 patients with suspected maxillofacial fractures, out of which 26 were male (86.7%) and 4 were female (13.3%). After initial management, detailed clinical examinations were carried out and significant findings were noted. Computed tomography (CT) scans were performed in fracture-suspecting patients followed by USG examination which was done in a standardized pattern on both sides of the face. The result of USG was compared with the CT scan report.

RESULT

Based on CT findings, 65 sites were found to be fractured, and this was considered the gold standard. Ultrasonography detected 58 fractures at these 780 sites, of which 54 were true fractures, while 4 were false-positive results. However, USG was not able to detect eleven fractures. The overall sensitivity and specificity of USG were 83.1% and 99%, respectively. The positive and negative predictive values were 93% and 98%, respectively.

CONCLUSION

According to our study, it may be concluded that USG may be recommended as a diagnostic screening tool to detect superficial maxillofacial fractures.

CLINICAL SIGNIFICANCE

Ultrasonography provides a safe, cost-effective, reliable, non-invasive, easily available, and portable imaging modality to screen for maxillofacial fractures.

Evaluation of Microbial Adherence on Antibacterial Suture Materials during Intraoral Wound Healing: A Prospective Comparative Study

AIM

To assess the efficacy of antiseptic-coated silk sutures with triclosan-coated polyglactin 910 suture in reducing bacterial colonization after oral surgical procedures.

MATERIALS AND METHODS

The patients who required multiple sutures after surgical procedures in the mandible were the study subjects. The sites of suturing were divided into three groups. Group A - surgical site receiving black-braided silk suture (control group). Group B - surgical site receiving triclosan-coated Polyglactin 910 suture (experimental group). Group C - surgical site receiving antiseptic-coated silk suture (experimental group). Evaluation was done on the 3rd postoperative and 7th postoperative day. Microbial adherence was evaluated by microbiological study.

RESULTS

The mean comparison of microbial count between 3rd and 7th post-op day in the three groups shows an increased microbial colonization in the control group when compared with the experimental groups. The combined mean microbial adherence in the three groups showed microbial count in the uncoated silk suture (group A) as 10.35 ± 3.74, triclosan-coated suture (group B) as 6.28 ± 2.17 and iodoform + calendula oil-coated suture (group C) as 7.1 ± 2.02 which is statistically significant (p < 0.05).

CONCLUSION

The present research concluded that the pomade-coated silk suture is as efficient as triclosan-coated VICRYL PLUS Polyglactin 910 sutures in reducing the bacterial colonization in intraoral wound healing.

CLINICAL SIGNIFICANCE

The pomade (iodoform + calendula oil) may be advocated in the field of oral and maxillofacial surgery for impregnating the suture materials which act as an antiseptic agent and a promoter of wound healing which is easily accessible and also cost-effective.

Evaluating the Clinical Efficacy of Maxillary Labial Frenectomy Procedure Using Diode Laser (980 nm) and Conventional Scalpel: An Observational Study

Aim

This is an era of minimally invasive and least traumatic surgical interventions being focused on. The traditional scalpel frenectomy technique offers an increase in post-operative sequelae. To unravel this scenario a comparative evaluation is carried out to find out the clinical outcomes and quality of life after maxillary labial frenectomy using a conventional scalpel and diode laser frenectomy of 980 nm.

Materials and Methods

Thirty-six subjects age ranging between 18 and 45 years reported to the Department of Oral and Maxillofacial Surgery, MES Dental College, Perinthalmanna with an aberrant frenal attachment of maxillary labial frenum were randomly assigned into two groups. Group A underwent the conventional scalpel technique and group B for the diode laser-assisted (980 nm) frenectomy technique. The post-operative parameters of ooze from the surgical site, pain, wound healing, and discomfort or acceptance of the procedure were assessed on day 1, day 7, and day 14, respectively.

Results

The diode laser group exhibited statistically significant clinical and healing outcomes. Less pain, minimal or absent ooze, increased healing, and better acceptance of the procedure with diode laser at 1, 7, and 14 days recall visit.

Conclusion

Surgical interventions involving needle puncture and the associated post-operative sequelae are the most dreaded experiences that make patients indifferent toward surgical treatments. Thus in terms of better clinical outcomes and improved quality of life diode laser frenectomy is an excellent alternative wherein a needleless anesthetic success followed by minimal surgical intervention and less post-operative sequelae with fast recovery is possible.

Conventional Rotary Technique and Piezosurgical Technique in the Removal of Impacted Mandibular Third Molar: A Comparative Study

AIM

To compare the operating time, postoperative pain, edema, trismus, and patient acceptance following surgical removal of impacted third molar using piezosurgery and conventional rotary technique.

MATERIALS AND METHODS

About 42 patients with impacted mesioangular mandibular third molars were included in this study. Subjects are divided into two groups: group I (treated with conventional rotary technique) and group II (treated with piezosurgery). Duration of surgery, pain, trismus, and swelling were assessed. The patients were evaluated on the 1st, 3rd, and 7th postoperative days.

RESULTS

Postoperative pain, trismus, and edema were reduced with piezosurgery compared with conventional technique. Even though the duration of time was longer with piezosurgery, patient comfort was found to be better.

CONCLUSION

Piezosurgery is a meticulous and innovative ultrasonic technique with selective bone cutting and better postoperative outcomes. However, it is expensive, and the operating time is prolonged.

CLINICAL SIGNIFICANCE

Piezosurgery is an alternative in the surgical removal of third molars as it ensures precise and selective cutting, with no injury to the surrounding soft tissues. Postoperative outcome and patient acceptance are improved with piezosurgery.

Low-concentration Povidone-iodine and Normal Saline as Irrigant on Reducing Postoperative Complications after the Third-molar Surgery: A Comparative Study

AIM

This study was conducted to compare the efficacy of using 0.5 mg/mL povidone-iodine solution as an irrigant and coolant in reducing postoperative sequelae like swelling, trismus, and pain with the conventional normal saline irrigation during the surgical removal of the impacted lower third molar.

MATERIALS AND METHODS

The research was conducted out toward the MES Dental College in Perinthalmanna, Kerala, in the Department of Oral and Maxillofacial Surgery. After mandibular third-molar surgical removal, researchers studied 60 individuals, 30 of whom had normal saline irrigation (group I), and 30 of whom received 0.05% povidone-iodine irrigation (group II). The postoperative discomforts were measured on the second and seventh days after surgery, respectively. After that, the data were analyzed using SPSS. The data analysis considered p-values less than 0.05 to be significant.

RESULTS

At the second postoperative visit, patients in the povidone-iodine group reported much less pain, swelling, and reduced mouth opening than those in the normal saline group. But on the seventh postoperative day, there was not much difference between either group.

CONCLUSION

Following the surgical removal of teeth, it was revealed that povidone-iodine solution (0.5 mg/mL) was more effective as irrigation and cooling aid than regular saline solution.

CLINICAL SIGNIFICANCE

Low-concentrated povidone-iodine is a better option in dentistry as irrigant.

Familial nesidioblastosis: more evidence for autosomal recessive inheritance

Severe neonatal hypoglycaemia in five Saudi Arab infants of both sexes belonging to two families of consanguineous parents is reported. All of these infants needed sub-total pancreatectomy to maintain normoglycaemia. Histopathological studies with immunohistochemistry proved diffuse nesidioblastosis of the pancreas in all five infants. Data obtained from these families and other families reported in the literature strongly suggest that familial nesidioblastosis is an autosomal recessive disorder. Knowledge of the inheritance pattern is important both for genetic counselling and for making a prompt diagnosis in subsequently affected siblings, as delay in appropriate treatment may have serious consequences.

Child abuse and neglect as seen in General Hospital, Kuala Lumpur--a two year study

Eighty-six children diagnosed as child abuse and/or neglect were admitted to the Paediatric wards of the General Hospital, Kuala Lumpur during 1985 and 1986. Of these cases, 62 were of physical abuse, six of sexual abuse, one case of both physical and sexual abuse and 17 of neglect. There were 25 boys and 61 girls. Thirty-four of these children were Malays, 16 Chinese, 26 Indians, three mixed and seven illegal immigrants. Twenty-one were below the age of one year, 24 from one to four years, 25 from five to nine years and 16 were ten years and above. The abusers were mainly close members of the family. Of these children, 24 were sent back to their parents and 11 to their relatives home. Twenty-seven were taken into care by the Ministry of Social Welfare and the remaining seven children who were illegal immigrants, were deported with their parents. Only one child was successfully fostered. Eleven children were taken away from the hospital by their parents or guardians without the knowledge of the health staff. There were five deaths in the series.

Pulmonary atresia with ventricular septal defect in adult patients

Hemodynamic data and angiograms of 15 adult patients with pulmonary atresia and ventricular septal defect were reviewed to assess the pulmonary circulation and other associated features. The most common variety of pulmonary atresia was that of pulmonary valve, main pulmonary artery, and the confluence of pulmonary arteries (6 cases, 40%). The collateral vessels to the lungs were well developed in all cases; selective injections into the collateral vessels were of great value in their delineation. The left ventricle was well developed in 11 cases (73.3%). Congestive heart failure was seen in 8 (53.3%), tricuspid regurgitation in 10 (66.7%), and aortic regurgitation in 7 (46.7%) cases. The long survival in these patients was related to the favorable anatomy of central pulmonary arteries (12 cases, 80%) and adequate pulmonary collateral circulation.
