Oral cancer is a cancer type that is widely prevalent in low-and middle-income countries with a high mortality rate, and poor quality of life for patients after treatment. Early treatment of cancer increases patient survival, improves quality of life and results in less morbidity and a better prognosis. To reach this goal, early detection of malignancies using technologies that can be used in remote and low resource areas is desirable. Such technologies should be affordable, accurate, and easy to use and interpret. This review surveys different technologies that have the potentials of implementation in primary health and general dental practice, considering global perspectives and with a focus on the population in India, where oral cancer is highly prevalent. The technologies reviewed include both sample-based methods, such as saliva and blood analysis and brush biopsy, and more direct screening of the oral cavity including fluorescence, Raman techniques, and optical coherence tomography. Digitalisation, followed by automated artificial intelligence based analysis, are key elements in facilitating wide access to these technologies, to non-specialist personnel and in rural areas, increasing quality and objectivity of the analysis while simultaneously reducing the labour and need for highly trained specialists.

Background: Obstructive Sleep Apnoea (OSA) is a common sleep disorder marked by partial or total obstruction of the upper airway while a person is asleep leading to breathing difficulty, reduced oxygenation and frequent awakenings. This condition affects the general health significantly compromising quality of life. The objective of this overview  is to thoroughly assess the systematic reviews on current surgical therapies for the management of OSA in terms of patient outcomes.

Methods: A thorough literature search was performed from inception till 31st December 2022 using PubMed, and Cochrane databases. Studies evaluating the effectiveness and safety of different surgical techniques for the management of OSA were considered. The quality of articles was assessed using AMSTAR (A MeaSurement Tool to Assess systematic Reviews) and Glenny et al. checklist.

Results: Out of eighteen studies, only seven studies met the inclusion and exclusion criteria. Results showed that the majority of studies were in the pediatric age group except one systematic  review which assessed the adult age group.

Conclusion: None of the published articles had compared all surgical procedures based on the standard evaluating procedure nor followed all reporting guidelines in the primary studies. For better implementation, further multi center studies are warranted with unique reporting criteria and guidelines about pre- as well as post-operative phases. Future research should concentrate on contrasting strategies, combination therapies, and evaluating long-term effects.

Objective: This study aimed to compare the difference between analyzing skeletal stability after orthognathic surgery by lateral cephalogram measurement created from Dolphin software (version 11.95) compared with the manual technique.

Methods: Twenty-eight patients who underwent mandibular setback surgery (BSSRO) were randomly selected between 2015 and 2021. Serial lateral cephalograms were analyzed at four different time sets postoperatively, and a total of 112 cephalometric radiographs were obtained. Horizontal measurement (BX), vertical measurement (BY), and 3 angular measurements (SNB, ANB, and Gonial angle) were analyzed by manual tracing and Dolphin software by 2 examiners. The intraclass correlation coefficient determined the intra-rater reliability. Parameter differences between timelines were observed for skeletal stability, and mean values between methods were compared using the Student's t-test.

Results: Both examiners were generally consistent in the repeated measurements (ICCs of the manual method ranged from 0.926 to 0.994, and the digital method ranged from 0.719 to 0.956). All variables represented skeletal stability at T0-T1, T0-T2, and T0-T3 showed no statistically significant differences between methods except ANB (T0-T1; p value = 0.009).

Conclusions: Computerized cephalometric analysis software is relatively reproducible for assessing skeletal changes after orthognathic surgery and can be used routinely in follow-up.

Objectives: This retrospective study aimed to determine the angulation changes of the proximal segment following bilateral sagittal split osteotomy (BSSO) setback and its correlation with the amount of immediate postoperative surgical movement. The correlation between postoperative relapse of the distal and proximal segment at six months postoperatively was also evaluated.

Materials and methods: The CBCT-generated lateral cephalometric images of 39 patients who underwent BSSO setback with or without Le Fort I osteotomy were evaluated preoperatively (T0), immediately postoperative (T1), and six months postoperatively (T2).

Results: The mean surgical setback was 7.28 ± 4.45 mm at B point. The proximal segment's immediate postoperative mean posterior rotation was 2.13 ± 3.59 degrees. Six months after the operation, the mean distal segment relapse was 0.89 ± 3.03 mm at B point. The proximal segment relapse was 0.81 ± 1.63 degrees. A significant moderate correlation was found (P < 0.05) between the surgical movement and the immediate postoperative proximal segment rotation and between the surgical movement and the distal segment relapse. A significant correlation was found between the distal segment relapse and the average and left proximal segment relapse. There was no significant correlation between immediate postoperative proximal segment rotation and distal segment relapse.

Conclusion: The immediate postoperative posterior rotation of the proximal segment had a negligible effect on mandibular relapse. The amount of surgical movement, on the other hand, was more related to distal segment relapse. The intraoperative proximal segment rotation should thus be minimized in cases with a significant surgical setback.

Among the rare congenital malformations, congenital nasal sinuses with blind end are extremely unusual. To the best of our knowledge, a sinus located in the midcolumellar region has not been reported yet. Since there is no consensus about the treatment of midcolumellar sinus, to manage the case as individually as possible was our priority. Considering the patient's age, aesthetic concerns, and requirement of septorhinoplasty in the future, the known inverted V incision was modified to provide surgical excision without any extra scar in the midcolumellar line. This report emphasizes a patient-specific treatment of a 15-year-old female patient presented for congenital sinus in the midcolumellar area.

Short face syndrome (SFS) is a condition with a clinical impression of deficient lower anterior facial height, which is an esthetic disharmony based on vertical facial proportions rather than absolute dimensions. Masseter hypertrophy is one of the etiologic factors in which there is an enlargement of unilateral or bilateral masseter muscles. Clinically, it presents as a quadrangular face characterized by bulging of the mandibular angle giving a muscular appearance. Despite the muscular origin, surgery should be aimed toward bony reduction (osteoplasty) followed by supplemented myotomy. This case report addresses one such case of SFS treated with surgery-first approach and supplemented myotomy with a 1-year follow-up. The esthetic facial profile, pleasant smile and overall good treatment outcome remained stable 1 year after orthognathic surgery and orthodontic treatment.

Introduction/background: Perfect facial symmetry has always been considered a hallmark of beauty, but, is almost elusive in nature. However, clinically evident skeletal facial asymmetry on the other hand is quite common, which can result from congenital deformities, developmental abnormalities, secondary to maxillofacial trauma and it is an entity maxillofacial surgeons deal with on a regular basis. Surgical correction of facial asymmetry is challenging, as it not only involves the correction of the skeletal asymmetry for an aesthetic outcome, but, also the improvement of the soft tissue drape and dental occlusal harmony. This results in rehabilitation of functional components of orofacial complex like speech, deglutition and phonation.

Objective: With this paper, we intend to throw a light on this challenging aspect of maxillofacial surgery, along with giving the next generation of maxillofacial surgeons a direction to explore the topic further.

Conclusion: Meticulous evaluation and diagnosis of the patient's problems with latest diagnostic methods like 3-dimensional imaging and surgical treatment with orthognathic surgery, gap arthroplasty or distraction osteogenesis, utilizing cutting edge 3-D virtual planning will result in better outcomes.This review will collate the information available in the literature, along with the authors' recommendations for better planning and execution of this challenging puzzle of facial asymmetry.

Introduction: Primary cleft lip repair techniques do not address the nasal deformity adequately resulting in nasal asymmetry. Maneuvers employed to minimize this have varying degrees of success.

Aim: To assess the outcome of different treatment modalities employed to establish nasal symmetry in unilateral cleft lip.

Methods: 100 patients with complete unilateral cleft lip/ palate operated for primary cheiloplasty with modified Millard's rotation advancement technique were divided into five groups. Group 1: lip repair alone, Group 2: NAM followed by lip repair, Group 3: lip repair followed by placement of conformers, Group 4: NAM followed by lip repair and placement of conformers, Group 5: lip repair with semi-open rhinoplasty. Objective assessment was done using measurable parameters after 12 months post-operatively on a 1:1 standard photograph.

Results: Group 5 showed statistical significance in all parameters assessed. Progressive improvement in nasal symmetry was noted from Group 1 to Group V.

Conclusion: In our study, group V, i.e., modified Millard's repair with semi-open rhinoplasty improved the results in terms of all the objective parameters assessed. The results of the other groups showed improvement though not consistent in all parameters. Naso-alveolar molding is an effective adjunct. Additionally, nasal conformers proved to be of great value in retaining the results obtained post-surgery.

Condylar hyperplasia is a rare pathology characterised by excessive bone growth that presents virtually unilaterally, resulting in facial asymmetry. The aetiology of this disorder is not well understood. This pathology has been reported to be a rare entity with very few cases being reported in the literature, mostly seen between 11 and 30 years of age, with males and females being equally affected and having no predominance to the left or right side. It has also been reported to be a self-limiting condition, that is, the active growth can cease at any point in time. We report two cases of unilateral condylar hyperplasia in 24- and 19-year-old male and female patients, where the first was treated by condylectomy and BSSO, and the latter was treated by high condylectomy and recontouring of the mandible.

Background: Ocular hypertelorism (OH) was initially considered as un-differentiated congenital cranio-facial deformity, however, I.T Jackson mentioned it as teleorbitism, considering it as increase in the inter-canthal width, inter-pupillary as well as inter-orbital distance as a result of lateralization of the orbital complex in total. Furthermore, Sailer further refined it and included the distance from the lateral orbital wall, i.e. he denoted increased inter-orbital distance along with the distance between lateral orbital walls as true hypertelorism. This condition is rare and is seen in association with midline congenital defects affecting the cranio-facial region.

Classification and review of cases: The ideal time for the OH correction is usually between 5 and 8 years of age. However, the management of OH is complex, and several techniques have been described in literature for the same. Here, we describe our classification of OH, along with the evolution of the surgical aspects, the key treatment principles we follow, together with the types of the osteotomies and their indications. Furthermore, we delineate the four main principles that we have set for OH management.

Results: Though the improvement in appearance is seen immediately post-surgery, however, this challenging surgery faces a multitude and common postoperative complications which have been represented in this article. The surgeon needs both the technical expertise and an inclination towards aesthetics for the execution of such procedures.

Conclusion: It is preferred that the management of OH should be individualized as per the stage of the craniofacial growth and the psychosocial needs of the patient and the parents.
