The cost of care in maxillofacial fractures treatment in relation to the type of fixation and length of stay at a tertiary care hospital of Karachi, Pakistan: A retrospective chart review.

In addition to the clinical burden of trauma, the financial burden is an important aspect of care globally, especially for patients in low- and middle-income countries. The current retrospective review was done of data from January 2015 to December 2020 related to patients of oral maxillofacial trauma management in a tertiary care setting. Analysis of variance was used to determine the mean difference in the cost incurred depending upon the type of trauma and the number of bone plates used in fracture management. Pearson correlation was applied to explore any correlation involving patient age, aetiology and type of fracture, number of bone plates employed and the length of stay in the hospital. No statistically significant differences were noted in the cost among the different groups. The cost of care was significantly (p<0.001) correlated to the length of stay. Other variables, such as the type of fractures and the number of plates, had no significant impact (p>0.05).

Is There A Difference Between Disease-Free Survival Of Oral Squamous Cell Carcinoma Referred By Dentists Versus Other Physicians? A Systematic Review.

Objective: To compare disease-free survival rates in oral squamous cell carcinoma patients initially attended and referred by dentists versus other physicians. METHODS: The systematic review was conducted after registration with the International prospective register of systematic reviews at the University of York, the United Kingdom, and comprised search on Medline, PubMed, Cochrane and CINAHAL Plus databases for studies published up to December 2021. The Population-Intervention-Comparison- Outcomes-Study criteria was used to search for studies involving patients diagnosed with oral squamous cell carcinoma receiving referrals by dentist or by other healthcare providers. Disease-free survival of patients was taken as the main outcome. Customized data collection proforma was used to record data in line with the Preferred Reporting Items in Systematic Reviews and Meta- Analysis guidelines. Data was subjected to systematic, qualitative review. RESULTS: Of the 344 studies found, 8(2.3%) were analysed in detail. Patients referred by dentists ranged from 22.6% to 54%. Males comprised 53% to 70.3% of the sample. The highest number of referrals was made by primary physicians, ranging from 27.4% to 71.6%. Upto 67.6% cases were diagnosed with stage 1 and 2 oral cancer. The highest 5-year survival rate was 75% in a study where 59% patients were diagnosed at an early stage of disease. Conclusion: The relative scarcity of studies makes it impossible to draw an association between oral cancer survival rate and type of referral.

Relationship of maxillary third molar root to the maxillary sinus wall: A cone-beam computed tomography (CBCT) based study.

Background: The relationship of the root of the maxillary third molars and the maxillary sinus (MS) is an important predictor of the anticipated difficulty in extraction. The aim of this study was to assess the location of maxillary third molars to the inferior wall of the MS in a sample of Pakistani population evaluated using cone-beam computed tomography (CBCT) imaging and to assess if age or gender has any influence on third molar to MS distance. Methods: The CBCT scans of adult patients, carried out keeping image volume at 8 cm×8 cm, and the voxel size 0.2 and 0.1 mm. Images retrieved from the hospital database were included in the study. The relationship of root apices of maxillary third molar with the MS was assessed according to the vertical, horizontal and Winter's classification. Descriptive statistics, t test and chi-square test of association were applied. Results: CBCT scans of 93 patients, 56 males and 37 females were evaluated. The mean age was 41.12±17.13 years. The mean distance of third molar roots to the MS wall was 2.38±1.54 mm for males and 1.86±1.04 mm for females, on the left and 2.67±1.81 mm for males and 2.58±1.54 mm in females, on the right side. Independent sample t test showed that there was no significant difference for third molar to sinus wall distance in the two genders. No significant difference was found between the two sides. Conclusion: In a sub-population of Pakistani adults, the mean distance between the roots of the upper third molar and MS wall is around 2 mm. Only 5% males and 8% females had their upper third molars roots protruding into the MS.

Oral maxillofacial surgical residency and its impact on the academic and research productivity at different levels in Pakistan.

Oral and maxillofacial (OMF) surgery is a unique speciality. In many countries, OMFS is a dental speciality but the scope of its practice significantly overlaps with other specialities, including otolaryngology, head and neck surgery, plastic surgery, and orthopaedics. Thus, OMF surgery represents a true amalgamation of medical and dental specialities. There are different requirements of OMF residency training, which include a dental undergraduate training, medical training, or both. The training pathways for this speciality have evolved much in the last three decades and there is still no consensus over a single uniform path of becoming an OMF surgeon. An OMF surgeon deals with trauma, cysts, tumours and other pathologies of the maxilla, mandible, and zygomatic complex that need surgical correction. In addition to being a diverse speciality, the academic and research domains of residency have also changed. In Pakistan, residency training in OMF surgery started in 1994 and since then a lot of growth has taken place. This paper summarises the evolution and scope of OMF surgery and the contribution of this speciality in the overall academia and research in Pakistan's national dental scenario.
