[Show abstract][Hide abstract] ABSTRACT: Background:
Distraction osteogenesis (DO) is a biologic process of new bone formation between the surfaces of bone segments that are gradually separated by incremental traction. It consists of 4 primary phases, namely, corticotomy and device placement, a latency period, active distraction, and consolidation. The objectives of the current study were to review DO as it applies to maxillomandibular defects and to share our clinical experience in the cases we have done.
A clinical narrative review of the literature was performed to evaluate the use and efficacy of maxillomandibular osteogenesis in maxillomandibular defects. A systematic search of the literature was performed using PubMed, with special interest in the history of DO and its application in dentistry and maxillofacial surgery. medical subject headings terms included surgical procedures, osteogenesis, distraction, and orthodontics. Two cases of maxillomandibular DO managed at the Aminu Kano Teaching Hospital (AKTH), Nigeria, were reported and discussed.
Articles involving maxillary and midface distractions, bilateral distraction for airway obstruction, and distraction for hemifacial microstomia were all reviewed. In the first case reported, a unidirectional distractor was used to achieve simultaneous mandibular lengthening and maxillary occlusal correction. Gains of 10 mm in mandibular ramal height and 23 mm in corpus length were achieved in the second reported case, using a bidirectional distractor. The literature search revealed no previous Nigerian reports of maxillomandibular DO.
The DO is a viable and available treatment option for reconstructing maxillomandibular discrepancies and accompanying soft and hard tissue deficiencies.

[Show abstract][Hide abstract] ABSTRACT: The aim of the present study was to determine the effect of saline mouth rinse on postoperative complications following routine dental extractions. Patients aged ≥16 years, who were referred to the oral surgery clinic with an indication for non-surgical extraction of pathologic teeth, were prospectively and uniformly randomized into three groups. Group A (n=40) were instructed to gargle six times daily with warm saline and group B (n=40) twice daily; group C (n=40) were not instructed to gargle with warm saline and served as controls. Information on demographic characteristics, indications for extraction, and the development of complications, such as alveolar osteitis, acute inflamed socket, and acute infected socket, was obtained and analyzed. There were no significant differences between patients who gargled six times daily with warm saline and those who gargled twice daily with reference to either alveolar osteitis or acute inflamed socket (P>0.05). However saline mouth rinses at either frequency were beneficial in the prevention of alveolar osteitis in comparison with those who did not rinse. A twice-daily saline mouth rinse regimen is more convenient, and patient compliance may be better than with a six times daily rinse regimen.

[Show abstract][Hide abstract] ABSTRACT: Abstract:
Aims and Objective: To highlight the value of case profiling in the management of penetrating craniofacial arrow injuries
Materials and Methods: This is a prospective analytical study of fourteen cases using case scenarios ,cadaveric skull and sample arrows
Results:This showed that the most important factor in the determination of morbidity was the anatomical site of injury. The depth of penetration was characteristically determined by the density of impact tissue. There is however, anecdotal evidence that a high depth of penetration may not present morbidity without a trajectory that favors it. The orbit was the most frequent site of penetration accounting for 5 cases.
Conclusion:Profiling of craniomaxillofacial arrow wounds is vital to maximizing the goal of management which ,is a morbidity free outcome of definitive care.
[Show abstract][Hide abstract] ABSTRACT: : Traditional healers/herbalists remain one of the most accessible and popular options of care to people suffering from cancers particularly at the community level in Nigeria. The majority of patients with oral cancer present at the terminal stage after exploring unorthodox care. This study assesses the awareness of oral cancer among traditional caregivers in Kano State, Northwestern (NW) Nigeria.
: Self-administered, structured questionnaires were administered to a cross section of 21 traditional caregivers.
: Of the 21 traditional caregivers studied, the majority (66.7%) had never heard of oral cancer and only 7 (33.3%) were aware. The level of knowledge on oral cancer was assessed using a scoring system classifying respondents as having adequate (>50%) or inadequate (
[Show abstract][Hide abstract] ABSTRACT: Squamous Odontogenic tumor (SOT) is an uncommon benign tumor believed to originate from the epithelial root sheath of Hertwig. This paper reports SOT in a 50-year-old man who presented to the Maxillofacial Unit of the Aminu Kano Teaching Hospital with a 2-year history of an extensive swelling of the left half of the maxilla.
Both incisional biopsy and histology of the final tissue specimen were reported as SOT despite the different radiographic features commonly associated with the lesion. In view of the large and extensive nature of this tumor, and its rarity in scientific literature, this case is being presented to add to literature.
[Show abstract][Hide abstract] ABSTRACT: The aim of this prospective randomized study was to evaluate the effect of not using sutures on postoperative pain, swelling and trismus after lower third molar surgery. 80 patients with impacted lower third molars were referred for surgical extraction (42 males; 38 females; aged 18-38 years). The patients were randomly divided into two equal groups (sutures n=40; suture-less n=40). In the experimental group, the flaps were replaced without suturing. The control group was selected using the same criteria and treated under the same surgical protocol as the experimental group, except that the flaps were apposed using multiple sutures. Pain, swelling and trismus were evaluated at 24 h, 48 h and 1 week postoperatively in both groups. The operation time was found to be significantly longer in the multiple sutures group (p<0.05). There was significantly less pain, swelling and trismus at 24 h and 48 h, respectively, in the suture-less group (p<0.05). There was no significant difference between the two treatment groups in terms of pain, swelling and trismus, at 1 week postoperatively (p>0.05). There is less postoperative pain, swelling and trismus with the suture-less technique in third molar surgery.

[Show abstract][Hide abstract] ABSTRACT: Pain, swelling and trismus are common complications associated with third molar surgery. These complications have been reported to have an adverse effect on the quality of life of patients undergoing third molar surgery.
To review the different modalities of minimizing inflammatory complications in third molar surgery.
A medline literature search was performed to identify articles on management of inflammatory complications in third molar surgery. Standard textbooks of Oral and Maxillofacial Surgery were also consulted and some local scientific publications on the subject were reviewed.
Methods ranges from surgical closure techniques, use of drains, physical therapy and pharmacological means. Studies reviewed have shown that no single modality effectively minimizes postoperative pain, swelling and trismus without undesirable effects.
Inflammatory complications after third molar surgery still remains an important factor in quality of life of patients at the early postoperative periods. Oral surgeons should be aware of the different modalities of alleviation of these complications to make postoperative recovery more comfortable for patients.

[Show abstract][Hide abstract] ABSTRACT: The goal of the maxillofacial surgeon is to correct facial deformity while eradicating surgical diseases, prevent recurrence or complication and restore function. The aim of this paper is to review the surgical procedures carried out in a new tertiary teaching hospital. A retrospective study of patients with maxillofacial surgical diseases seen at the Department of Dental and Maxillofacial Surgery, Aminu Kano Teaching Hospital, Kano, Nigeria, between 2001 and 2003, was conducted. A total of 87 patients had various (primary and secondary) surgical procedures during the period under review. There were 51 males and 36 females, a male to female ratio of 1:0.61 with an age range of 3 days to 90 years and a mean age of 34.5 years. The majority of the patients were in the lower socio-economic group. Reduction and immobilization of the jaw fractures (n = 21, 23.3%) was the most common, followed by transosseous wiring (n = 12, 13.3%). The most common complications were malocclusion (n = 14, 29.8%) and facial defects (n = 12, 25.5%). Reduction and immobilization, and tumour surgery of the jaws seem to be the most common surgical procedures while osteotomy was the least. Reduction and immobilization with simple arch bars appeared to be very effective, more so when the patients could not afford more modern methods of treatment. Reconstructive surgeries of ablated jaws are advocated in view of the devastating aesthetic and psychosocial effects that these have on the patients.

[Show abstract][Hide abstract] ABSTRACT: Background: Orofacial tumours are known to exhibit geographic variations in prevalence and pattern due to cultural, social, occupational or climatic factors.
Method: A retrospective study of orofacial tumours presenting in a new maxillofacial centre in Nigeria between March 2001 and August 2002.
Result: A total of 342 patients attended the maxillofacial clinic within the 18-month period out of which 69(20.2%) had orofacial tumours. Only 55 case notes made up of
29(52.7%) males and 26(47.3%) females (M: F=1.1:1) were retrievable. The mean age was 37.1years(S.D: +/-18.5) with a range of 1 - 70 years .The peak age incidence was in the sixth decade for all tumours, third decade for benign and sixth decade for malignant tumours. The most prevalent tumours were squamous cell carcinoma (46% of malignant lesions) and ameloblastoma (31% of benign lesions) the mandible (38.2%) and the maxilla (23.6%) were the most commonly affected sites. Patients usually delayed before seeking treatment and the mean duration of tumours was 30 months (range=3 weeks - 40 years). More than a third (36.4%) of the patients could not afford cost of treatment and defaulted after diagnosis. Fifteen (27.3%) were referred for palliative radiotherapy due to advanced state of tumour. Out of the 14 (25.5%) treated, 4 had hemimandibulectomy, 1 subtotal mandibulectomy, 2 hemimandibulectomy and radiotherapy, 1 segmental resection and radiotherapy and 6 excisions. Follow-up records were scanty as patients tended to default shortly after treatment. The mean Follow-up period was 4.7 weeks (range= 1 - 22 weeks). Problems associated with management included late presentation resulting in advanced tumours, inability to pay for treatment due to poverty, difficulty in reconstruction and rehabilitation due to cost, size of tumour and non-availability of suitable materials for reconstruction.
Conclusion: Orofacial tumours and tumour-like conditions are commonly seen in our environment but usually present late.
