Role of Platelet Rich Fibrin in the Closure of Oronasal Fistula. A Case Report.

An oronasal fistula is an abnormal opening connecting the oral cavity and the nose. They could occur as complications of oral and maxillofacial procedures. Oronasal fistulas (ONF) are challenging to repair optimally. The repair of a recurrent ONF is more of an enigma in cases where a small defect often requires an extensive surgery to close. Platelet rich fibrin (PRF) was described by Choukroun as a platelet concentrate from autologous blood which forms a single fibrin biomaterial after centrifugation. This haemostatic plug rich in growth factors is easy to prepare, manipulate; and adapt for soft and hard tissue healing. It has been utilized in the various fields of dentistry especially oral and maxillofacial surgery. Reports of role of PRF in the repair of ONF closure are scarce in literature especially in conjunction with other soft tissue flaps. This case report highlights that PRF can be used with success as an adjunct for the closure of ONF fistulas.

Is Blood Transfusion Justified During Soft Tissue Surgery in Noma Patients? A One-Year Appraisal at Noma Children Hospital, Sokoto, Nigeria.

Background: Non-utilization of blood and inappropriate blood transfusion are common in surgical operations. Some surgical procedures are associated with minimal bleeding that does not warrant blood transfusion. No previous study has looked at the pattern of blood loss in noma defect repair to determine the possible need for blood transfusion. Aim/Objectives: This study aimed to determine the total amount of blood loss, the number of units of blood transfused, and the correlation between estimated blood loss and total operating time in patients who had surgical correction of noma defects. Materials and Methods: This is a hospital-based cross-sectional study of 35 patients who underwent surgical correction of noma defects. Age, sex, pre- and post-operative haemoglobin (Hb), number of requested blood units, total operating time, and total estimated blood loss were recorded. The methods used for the blood loss estimation were gauze swabs, Abdo-packs, drapes, and suction bottles. Results: Comparison of the mean pre- and post-operative Hb did not yield any statistically significant difference. The total estimated blood loss in these surgeries was in the range of 65-209 mL, with a mean of 117.20 ± 35.88 mL. No correlation between estimated blood loss and total operating time was noted (P = 0.940). No blood was transfused in any of the subjects. Conclusion: This study observed minimal blood loss in surgical corrections of the soft tissue noma defect. Apart from blood grouping, there may be no need for routine cross-matching of blood pre-operatively for surgical repair of noma defect. However, more studies are needed to buttress this finding.

Maxillofacial Bone Fractures in Children and Adolescents: Overview of 247 Cases in a Major Referral Hospital, Najran, Kingdom of Saudi Arabia.

STUDY DESIGN: A retrospective study investigating maxillofacial bone fractures in the pediatric and adolescent population. OBJECTIVE: The aim of this study was to present our experience in the management of pediatric facial bone fractures. METHODS: This was a retrospective study of maxillofacial bone fractures in children and adolescents between the ages <1 year and 19 years in a Saudi Arabian subpopulation. Data collected include demographics, etiology, pattern, and treatment of maxillofacial bone fractures. Data were analyzed using IBM SPSS Statistics for Windows Version 25 (IBM Corp.). Results were presented as simple frequencies and descriptive statistics. RESULTS: Of the 1297 patients with maxillofacial bone fractures, 247 were cases involving children and adolescents giving a prevalence of 19.0% (247 patients, N = 1297). There were 233 males and 14 females with an M:F ratio of 16.6:1. The ages ranged from 9 months to 19 years with a mean ± SD of 14.4 ± 4.6. The age-group between 16 and 20 years had the highest frequency of patients (144 (58.4%)). In the 1- to 5-year group, falls accounted for most of the etiology (15 (6.1%)), while in the 16- to 20-year group, motor vehicular accident (MVA) was the main reason (120 (48.6%)). The majority of the fractures occurred in the mandible with 151(61.1%) cases. Open reduction and internal fixation (ORIF) were the main treatment modality in 171 (69.2%) patients. CONCLUSIONS: MVA was the main etiology of maxillofacial fractures in children and adolescents with male predominance, while the mandible had been the most frequently fractured bone. ORIF was the main treatment modality.

Oral Health-related Quality of Life (OHRQoL) Following Surgical Extraction of Impacted Mandibular Third Molars: Preliminary Observations in a Saudi Arabian Subpopulation.

Introduction: OHQoL is crucial for the best preoperative assessment and development of suitable indications for mandibular third molar surgical extraction. The current study hopes to report QoL after surgical extraction of impacted mandibular third molars. Materials and Methods: This was a prospective study conducted in the Department of Oral and Maxillofacial Surgery, between January 2020 and April 2020. After consenting to partake in the study, patients' baseline demographics, indication for seeking third molar removal and laterality of impaction were recorded. All the surgical extractions were performed by the same surgeon. Pain was assessed pre and postoperatively with the numerical pain rating scale while QoL was assessed pre and postoperatively using the validated Arabic version of the 16 item United Kingdom Oral Health Related Quality of Life measure (UK-OHQoL). Results: A total of 92 patients were recruited. There are 41 (44.6%) males and 51 (55.4%) females with M:F of 1:1.2. Age range was between 18 and 48 years with a mean of (31.2 ± 6.6) years. Age group 20-29 years constitutes the highest number of patients. Subscales: eating, appearance, sleep, mood and work revealed more percentage complaints (42.9%, 23.4%, 24.7%, 28.6%, and 16.9%, respectively). Regarding mean domain and overall QoL scores, it was observed that there was gradual improvement in mean scores from the Pre-op values and the review periods with best mean QoL reported at POD 14. Conclusion: Improvement in overall mean QoL scores during the review periods as compared with the preoperative score was observed. Eating, appearance, sleep, mood and work subscales revealed more percentage complaints.

Experience with Airway Management and Sequencing of Repair of Panfacial Fractures: A Single Tertiary Healthcare Appraisal in Najran, Kingdom of Saudi Arabia - A Retrospective Study.

INTRODUCTION: Special cooperation is required among surgeons and anesthetists in airway management during repair of panfacial fractures, due to problems of shared airway and occlusion. Several methods have been proposed for airway management and sequencing of repair of panfacial fractures. The main objective of the current study was to share our experience in the airway management and sequencing of repair of panfacial fractures. METHODS: This was a retrospective study of panfacial fractures in the Kingdom of Saudi Arabia from January 2008 to December 2018. Data collected included demographics, type of airway management, sequence of repair (as primary variables), and outcome of surgery (secondary variable), while surgeon and anesthetic expertise are confounders. Data were analyzed using IBM SPSS Statistics for Windows Version 25 (Armonk, NY, USA: IBM Corp). Results were presented as simple frequencies and descriptive statistics. Pearson Chi-square was used to compare categorical variables such as airway management and sequencing of repair with the panfacial fractures. Statistical significance was set at P ≤ 0.05. RESULTS: Overall, 1057 patients sustained different categories of maxillofacial bone fractures with 23 females and 1034 males (M:F of 46:1). A total of 43 male patients out of 1057 patients had panfacial fractures during the study period, giving a prevalence rate of 4.1%. Only the 43 male patients with panfacial fractures were analyzed. All cases were as a result of motor vehicular accident. Six (13.9%) patients had tracheostomy while 37 (86.1%) patients had submental intubation. "Bottom-up" and "outside-in" approach was used in 33 (76.7%) patients, while "top-bottom" and "inside-out" approach was used in 10 (23.3%) patients. DISCUSSION: Submental intubation was the major airway management of panfacial fracture, and "bottom-up" and "outside-in" approach was the main sequence of repair in our series. These approaches have been mentioned in the literature. CONCLUSION: From our study, victims of pan-facial fractures were found to be exclusively male with MVA as the sole etiological factor. Barring severe head injuries, which may necessitate the use of tracheostomy to sustain breathing over a longer period, submental intubation is extremely reliable as a mode of airway management during surgical treatment of panfacial fractures. The sequencing of repair of panfacial fractures can only be determined according to the case presentation rather than a predetermined one.

Mandibular reconstruction with autogenous non-vascularised bone graft.

BACKGROUND: Reconstruction of mandibular defects can be challenging because an acceptable aesthetic and functional outcome must be achieved simultaneously. AIM: To evaluate the pattern of mandibulectomy and reconstruction materials used in the reconstruction of mandibular defects. MATERIALS AND METHODS: This was a retrospective study of mandibulectomies with reconstruction in Sokoto, Nigeria between 2012 and 2016. Data such as demographics, type of tumour, type of resection and type of reconstruction materials used were extracted and stored. RESULTS: Fifty-two cases of mandibulectomies were done comprising 24 males and 28 females (ratio 1:1.2). Age ranged 5-80 years with mean±SD (37.8±15). Most of the cases 30 (57.7%) were on the right. There are 35 (67.3%) benign and 17 (32.7%) malignant cases. Thirty (57.7%) lateral, 16 (30.8%) condylar, 1 (1.9%) central and 5 (9.6%) combined mandibular defects were seen. Reconstruction plate alone was used in 11 (21.2%) cases, reconstruction plate with rib and tibia grafts in 16 (30.8%) cases, reconstruction plate with Iliac crest and tibia grafts in 15 (28.8%) cases. Graft length ranged from 0-20cm. There was satisfactory outcome altogether in 32 (80.0%). CONCLUSION: This study has shown the types of mandibulectomies and reconstruction materials used in our centre.

Descriptive epidemiology of salivary gland neoplasms in Nigeria: An AOPRC multicenter tertiary hospital study.

OBJECTIVES: Accurate diagnosis of salivary gland neoplasms (SGN) in many centers in Africa is limited by poor diagnostic resources and ancillary services. Hence, we have carried out a multicenter epidemiological study to understand the true burden of SGN in Nigeria. METHOD: In this descriptive cross-sectional study, we have deployed resources available to members of the African Oral Pathology Consortium (AOPRC) to examine the burden of salivary gland lesions in Nigeria, using a multicenter approach. Data from seven major tertiary health institutions in northern, western, and southern Nigeria were generated using a standardized data extraction format and analyzed using the Epi-info software (Version 7.0, Atlanta, USA). RESULT: Of the 497 cases examined across the seven centers, we observed that SGN occurred more in females than males. Overall, pleomorphic salivary adenoma (PA) was found to be the most common. PA was found to be the commonest benign SGN while adenocystic carcinoma (ADCC) was the commonest malignant SGN. Regional variations were observed for age group, diagnosis, and gender distribution. Significant statistical differences were found between males and females for malignant SGNs (p-value=0.037). CONCLUSION: We found regional variation in the pattern of distribution of SGN in Nigeria. This is the largest multicenter study of SGN in Nigeria, and our findings are robust and representative of the epidemiology of this neoplasm in Nigeria.

Self-esteem following maxillofacial and orthopedic injuries: preliminary observations in sub-Saharan Africans.

BACKGROUND: The face is a vital component of one's personality and body image while extremities are important in function (mobility, routine daily activities). Recovery and rehabilitation from acquired maxillofacial and orthopedic traumas are psychological in nature. METHODS: This was a prospective study of recruited subjects in a Nigerian University teaching hospital. A total of 160 participants (80 with maxillofacial injuries and 80 with orthopedic injuries) had repeated review assessments within 1 week of arrival in the hospital (time 1), 4-8 weeks after initial contact (time 2), and 10-12 weeks thereafter (time 3), using Rosenberg's Self-Esteem Questionnaire. RESULTS: Thirty-three (41.3%) participants in the maxillofacial injured and 12 (15.0%) in the orthopedic injured subjects scored between 0 and 14 at time 1. At time 2, 39 (51.3%) subjects in the maxillofacial fracture group and 20 (29.0%) in the orthopedic injured group scored between 0 and 14, while at time 3, 7 (9.2%) in the maxillofacial fracture group and 1 (1.5%) in the orthopedic injured group scored between 0 and 14. There was a statistical significant difference between the two groups when compared at times 1, 2, and 3 with p < 0.001, p = 0.006, and p = 0.041 respectively. Subjects with maxillofacial fracture consistently had lower self-esteem compared to subjects with orthopedic injured for times 1, 2, and 3. CONCLUSIONS: Self-esteem may be reduced following maxillofacial injuries; therefore, measures should be taken by surgeons to minimize the risk of facial scarring by careful handling of tissues. Also, management of these injuries should integrate multidisciplinary care that will address psychological needs of patients. TRIAL REGISTRATION: Not applicable.

Patterns of Zygomatic Complex Bone Fracture in Saudi Arabia.

INTRODUCTION: Zygomatic bone (ZB), also known as the cheekbone, articulates with the maxilla, temporal sphenoid, and the frontal bones. It forms the prominence of the cheek and part of the orbit, and because of its prominence, it is susceptible to trauma. The aim of this study was to present the pattern of ZB fracture in a country in the Middle East. PATIENTS AND METHODS: The medical records of all trauma cases admitted to the Department of Oral and Maxillofacial Surgery Ward, Riyadh Dental Centre, King Saud Medical City, Riyadh, Saudi Arabia, were reviewed and all cases with ZB fractures were included in this study from December 2002 to December 2012. Data were analyzed using SPSS version 16 (SPSS Inc., Chicago, IL, USA). The results were presented as simple frequencies and percentages. RESULTS: A total of 1487 patients had maxillofacial trauma and 306 cases were diagnosed with ZB fractures during the study. There were 271 (88.6%) males and 35 (11.4%) females with male: female ratio of 7.7:1. Age group of 21-30 years has the highest number of fracture cases (133 [43.5%]). Road traffic accident (RTA) remained the leading etiology of zygomatic complex fracture (ZMCF; 221 [72.2%]). August has been observed to be associated with the highest cases of ZMCF (40 [13.1%]). The years 2005 and 2006 recorded the highest frequency of ZMCF cases (46 [15.0%] and 44 [14.4%], respectively). CONCLUSION: The results of this study showed that RTA is the leading cause of ZB fractures followed by assaults. The most commonly fractured site was the zygomaticomaxillary. Proper road traffic regulation is paramount to help reduce maxillofacial trauma.

A 5-year audit of major maxillofacial surgeries at Usmanu Danfodiyo university teaching hospital, Nigeria.

BACKGROUND: There is a paucity of data on the pattern of oral and maxillofacial surgeries done in Nigeria. Despite the rising prominence of oral and maxillofacial surgery as a specialty in our immediate environment, no published audit of the surgeries performed exist. This study aims to present the pattern and types of major surgeries done by oral and maxillofacial surgeons in our hospital as well as the indications for such surgeries. It is hoped that the findings will assist in formulating informed policies and improving healthcare delivery. METHODS: A review of hospital records of all patients who had major oral and maxillofacial surgeries at Usmanu Danfodiyo University Teaching Hospital from January, 2013 to August, 2017 was done. Descriptive statistics such biodata, indication for surgery and type of surgery were recorded and analyzed using the IBM SPSS statistics for windows version 20 (Armonk, NY: IBM Corp) software. RESULTS: One hundred and forty six individuals who underwent 158 major surgeries under general anaesthesia were included. There were 82 males and 64 females, giving a male/female ratio of 1.3: 1. The ages ranged from 3 months to 81 years [median of 33 years]. Tumours and tumour-like lesions were the major indications for surgery [85 (58.2%)]. The most commonly performed surgery was mandibulectomy [31 (19.6%)], followed by Open Reduction and Internal Fixation (ORIF) [29 (18.4%)]. CONCLUSION: Major oral and maxillofacial surgeries are common in our environment. The frequencies of these surgeries can increase with better healthcare financing and universal availability of health insurance schemes. Efforts aimed at reducing the incidence of tumours should be instituted.

Pleomorphic Adenoma of the Upper Lip: A Case Report.

Pleomorphic adenoma is the most frequently encountered benign mixed tumor of the minor salivary gland and usually presents in the parotid; however, in the minor salivary gland, it is more common in the palate. Tumors of the minor salivary glands are uncommon, with the most common intraoral site reported being the hard and soft palate owing to the preponderance of minor salivary glands in this region followed by the lips. Pleomorphic adenoma arising from minor salivary glands of the lips tends to occur at an earlier age than it does at other sites. Pleomorphic adenoma of the lip is a rare neoplasm, and thus its diagnosis requires a high index of suspicion and a long-term follow-up. Here, the authors present a case of pleomorphic adenoma of the upper lip.

Tooth extraction: Pattern and etiology from extreme Northwestern Nigeria.

OBJECTIVE: Tooth extraction is a commonly performed procedure in dental clinics. It has been shown that the reasons for and pattern of tooth extraction vary across geographical regions. Few reports on the pattern of extraction among a semi-urban populace exist. To the best of our knowledge, there is no study on the pattern and reasons for tooth mortality from Sokoto, Northwestern Nigeria, which is a semi-urban region. MATERIALS AND METHODS: A review of the records of patients that had tooth extraction at our center between January 2009 and January 2016, was done. Data such as the age, gender, type of tooth extracted, and reasons for extraction were retrieved and analyzed. Cross tabulations for age and gender were also made. The level of statistical significance was set at P < 0.05. RESULTS: A total of 1167 extractions were performed in 984 patients. An age range of 18-107 years with a mean (±standard deviation) of 34.8 (13.3) was observed. Most of the patients were in the 21-30 years age group accounting for 35.7% of cases. Dental caries and its sequelae (DCS) (631, 54.1%) were the most common reasons for extraction, followed by periodontal disease (192, 16.5%). The difference in proportions of reasons for tooth extraction between the gender was statistically significant (P = 0.02; df = 24). The difference in the reasons for extraction among the age groups was statistically significant (P < 0.001; df = 132). CONCLUSION: DCS along with periodontal disease were the major reasons for extractions. These are largely preventable causes of tooth extraction; therefore, there is a need for commencement of far-reaching preventative actions.

Oral and maxillofacial tumours in children and adolescents: Clinicopathologic audit of 75 cases in an academic medical centre, Sokoto, Northwest Nigeria.

BACKGROUND: Maxillofacial tumours in children and adolescents have been documented worldwide; however, few studies were reported from Africa, especially sub-Saharan Africa. In Nigeria, most of the studies emanated from the Southwest region. AIM: To present an audit of clinicopathologic features and treatment of orofacial tumours in children and adolescents in Sokoto, Northwest Nigeria. PATIENTS AND METHODS: Clinicopathologic records of the Departments of Dental and Maxillofacial Surgery, Paediatrics and Histopathology, Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria, were reviewed for all the oral and maxillofacial tumours managed in children <19 years from January 2011 to December 2015. RESULTS: Two hundred and twenty-two tumours were noted in all age groups during the study duration and 75 (33.8%) of these occurred in children and adolescents. A total of 45 (60%) males and thirty (40%) females constitute the patient population with a male to female ratio of 1.5:1. There are 32 (42.7%) benign tumours and 43 (57.3%) malignant tumours. Burkitt's lymphoma was the most common malignant tumour in 24 cases (55.8%), whereas pleomorphic adenoma was the most common benign soft tissue tumour in 4 cases (30.8%) and fibro-osseous lesions were the most common benign jaw tumours in 10 cases (52.6%). Chemotherapy alone was the treatment modality in 24 cases of malignant tumour whereas 13 cases had combination chemotherapy and irradiation. CONCLUSIONS: Our findings established that oral and maxillofacial tumours in children and adolescents are quite common in Sokoto, Northwest region of Nigeria, particularly the malignant types. There is a need for improved universal healthcare insurance for all citizens to adequately manage these children effectively.

Comparative study of anxiety and depression following maxillofacial and orthopedic injuries. Study from a Nigerian University Teaching Hospital.

This study hopes to compare levels of anxiety and depression in the maxillofacial and orthopedic injured patients over a period of 12 weeks. This was a prospective, repeated measure design. A total of 160 participants (80 with maxillofacial and 80 with long bone fractures) had repeated review follow-ups within 1 week of arrival in the hospital (Time 1), 4-8 weeks after initial contact (Time 2) and 10-12 weeks thereafter (Time 3), using hospital anxiety and depression scale questionnaire. Road traffic accident remained the main cause of injury in both groups of subjects. The Hospital anxiety and Depression scale detected 42 (52.5%) cases of depression at baseline, 36 (47.4%) cases at Time 2, and 14 (18.4%) cases at Time 3 in the maxillofacial injured group. In the long bone fracture subjects, 47 (58.8%) cases were depressed at baseline, 23(33.3%) cases at Time 2, and only 5 (7.2%) cases at Time 3. Both groups showed reduction in depression levels with time. Fifty-six (70.0%) had anxiety at baseline, 32 (42.1%) at Time 2, and only 9 (11.8%) had anxiety at Time 3 in the maxillofacial fracture group, whereas in the long bone fracture group, 69 (86.3%) subjects were anxious at baseline, 32 (46.4%) at Time 2, and 22 (31.9%) at Time 3. There were significant differences in depression and anxiety level in both the maxillofacial and the long bone fracture subjects at baseline (Time 1), Time 2(4-8 weeks) and Time 3(10-12 weeks).

Comparative efficacy of amoxicillin/clavulanic acid and levofloxacin in the reduction of postsurgical sequelae after third molar surgery: a randomized, double-blind, clinical trial in a Nigerian university teaching hospital

Background: The most common sequelae after surgical removal of mandibular third molar are pain, trismus, swelling, and dysphagia. However, these symptoms can also signal the onset of surgical site infection and alveoli osteitis. The aim of this study was to evaluate the efficacy of prophylactic amoxicillin/clavulanic acid and levofloxacin and preemptive therapy of amoxicillin/clavulanic acid in the reduction of postinflammatory complications, surgical site infection, and alveolar osteitis following the third molar surgery. Patients and Methods: A total of 135 patients were randomized into three equal groups: Group A (preemptive therapy of amoxicillin/clavulanic acid) with preoperative dose of 875/125 mg amoxicillin/clavulanic acid followed by 500/125 mg amoxicillin/clavulanic acid 12 hourly for 5 days, Group B (amoxicillin/clavulanic acid prophylaxis) with a single preoperative dose of amoxicillin/clavulanic acid 875/125 mg tablets, and Group C (levofloxacin prophylaxis) with a single preoperative dose of levofloxacin 1000 mg tablets. All patients had ostectomy using surgical handpiece and burs and received same analgesics (tabs ibuprofen 400 mg 8 hourly for 3 days). Results: No case of surgical site infection or alveoli osteitis was recorded in the study groups.There were no statistically significant differences between the treatment groups with regard to pain, mouth opening, postoperative facial dimension, and body temperature. Conclusion: Amoxicillin/clavulanic acid as a single preoperative bolus should be adequate for the prevention of postoperative wound infection and alveoli osteitis following the third molar extraction as there is no need for an extension of the antibiotic. Moreover, levofloxacin can be utilized as prophylaxis in patients undergoing mandibular third molar extraction if such patients are allergic to penicillins

A multidisciplinary approach to the management of temporomandibular joint ankylosis in a sickle-cell anemia patient in a resource-limited setting.

This report describes the multidisciplinary management of a 35-year-old female sickle-cell anemia patient who had unilateral bony ankylosis of the left temporomandibular joint secondary to septic arthritis. She was managed by a team comprising of maxillofacial surgeons, anesthetists, otorhinolaryngologist, and hematologist. Unilateral left interpositional arthroplasty and ipsilateral coronoidectomy through a postrami approach were done and followed by aggressive jaw physiotherapy in the postsurgical period. No perioperative morbidity was encountered. Mouth opening of 3.5 cm was achieved and maintained 7 months after surgery. Challenges and rationale for the use of a multidisciplinary team approach in treatment of such cases were discussed.

Rare etiological factor of maxillofacial injury: Case series seen and managed in a tertiary referral centre.

Entanglement injury from local milling/grinding machine with a conveyor belt is a rare etiology of maxillofacial injuries. While there is abundant literature on industrial cause of trauma, entanglement injury as a mechanism has not been reported in the literature. We present two cases of maxillofacial injury secondary to entanglement of the loose apparel into the conveyor belt of the local grinding machine. The community should be aware of this rare cause of trauma, and adequate protection of children using these facilities should be enforced. One of such measure is to provide physical barriers to guard against these machines.

Oral health related quality of life (OHRQoL) following third molar surgery in Sub-Saharan Africans: an observational study.

INTRODUCTION: Surgical extraction of the impacted third molar is one of the commonest minor oral surgical procedures carried out in oral surgery. Problems created by the disturbances in post-extraction wound healing and physiologic sequelae of third molar surgery can significantly affect the patient's quality of life. METHODS: The study population consisted of 135 subjects that required surgical extraction of mandibular third molar under local anesthesia and met the inclusion criteria. Patients were assessed pre-operatively and post-operatively on days 1,3,5,7, and 14 using the United Kingdom Oral Health related Quality of Life questionnaire (UK-OHRQoL). RESULTS: This study also showed that surgical removal of impacted teeth exerted a negative influence on patient's Quality of life (QoL) across various physical, social, psychological aspects of life. UK-OHRQoL-16 mean scores showed that severe difficulty in eating was experienced by 106 (78%) patients on postoperative day (POD) 1. The symptom however improved within the first week with only 16 (11.9%) experiencing this symptom by POD 7 and none by POD 14. CONCLUSION: There was a deterioration in oral health related quality of life in the immediate postoperative period particularly POD 1 and 3 following third molar surgery, which slowly returned to preoperative level by 7th day. Routines such as eating, laughing and smiling, work and speech were also affected. Patients need to be informed of these symptoms after third molar removal so as to enable them prepare very well for the procedure and its sequelae.

Submental intubation in paediatric oral and maxillofacial surgery: Review of the literature and report of four cases.

Several oral and maxillofacial surgery procedures require the simultaneous use of the oropharyngeal space by both the surgeons and the anaesthetists. This poses a lot of challenges especially in optimally securing the airway. Nasotracheal intubation or tracheostomy with their significant morbidity might even be contraindicated in these scenarios owing to several factors elucidated in the literature. Submental endotracheal intubation might be the last resort in adequately protecting the airway without interfering with the surgery. It also permits concurrent access to the dental occlusion and nasal pyramid without the risk associated with nasal intubation and morbidity of tracheostomy. Contraindications include patients who require long periods of assisted ventilation and a severe traumatic wound on the floor of the mouth. Complications include localised infection and sepsis, poor wound healing or scarring, and post-operative salivary fistula. The rationale for this study is to describe the indications, contraindications and the technique of submental endotracheal intubation as performed in our hospital.
