Esthetic and functional rehabilitation in patients with cleft lip and palate.

Ann Maxillofac Surg 2015 Jan-Jun;5(1):108-11

University College Hospital, London, UK.

Rehabilitation of missing canine in cleft patients has acceptable success rates. A two-stage approach is indicated; however, timing of implant placement in the grafted maxilla varies within existing protocols. This case highlights successful implant osseointegration and esthetic rehabilitation following placement of two implants at 5 months after maxillary grafting (alveolar bone grafting) with a corticocancellous block obtained from the iliac crest. A 31-year-old male patient had already undergone repair of his bilateral cleft lip and soft palate according to established guidelines for cleft patients. Initial closure of his alveolar clefts and further correction of the maxillary hypoplasia with a bi-maxillary osteotomy were completed in 2002. However, bone resorption due to infection in 2003 necessitated removal of all maxillary incisors. The patient was not satisfied with the removable partial denture provided. In 2007, he did undergo anterior maxillary augmentation under general anesthesia, and 5 months later two implants were placed. A 3-unit bridge did replace functional and esthetic demands. Postoperative recovery was uneventful, and overall bone loss, and oral health remain within standards 28 months following implant placement. Optimal outcome is achievable when replacing missing teeth in cleft patients when timing does not exceed approximately a 6-month interval from bone grafting to implant placement.

Distraction osteogenesis of free flap reconstructed mandible following ameloblastoma resection for optimal functional rehabilitation

Ann Maxillofac Surg 2014;4:237-9.

Annals of Maxillofacial Surgery


A 27-year old patient at University College Hospital had her mandible reconstructed following wide excision of an ameloblastoma, hemi-mandibulectomy and reconstruction of her jaw with a fibula free flap (2.0 LOCK reconstruction plate). Extensive mandibular defects are commonly reconstructed with vascularized fibular flaps due to good bone quality and vascularization. The main drawback is limited neo-mandible diameter.

This patient had new bone with the use of a custom distractor (Synthes GmbH, Oberdorf, Switzerland) used to increase neo-mandible height following excision of an ameloblastoma

The primary significance of diagnosis and reduction of ZF suture fracture in midface zygomatic complex fractures

Hellenic Arch Oral Maxillofac Surg2013Oct

Hellenic Archives of Oral and Maxillofacial Surgery

       

Fractures of the midface vary from simple to complicated ones depending on:

- fracture of all zygoma buttresses

- fracture of the zygomatic arch and nasal bones

- involvement of the orbit and eye contents.

- loss of posterior facial height

CT investigations and accurate clinical diagnosis improve acceptable functional and aesthetic outcome. This patient sustained complex zygoma fracture with left zygoma (ZF, ZM butresses) fractures and left orbital rim and orbital floor. He had treatment with ORIF and an MEDPOR orbital implant.

Multiple Site Osteosarcomas of the jaw. A true case of a metachronous lesion?

Int J Oral Maxillofac Surg. 2010 Jul;39(7):733-6

International Journal of Oral and Maxillofacial Surgery

Multiple-site osteosarcomas in the jaw are a rare entity. The disease occured consecutively at 3 different sites (left maxilla, left mandible, right mandible), in one 56-year old female patient, separated by time intervals of 12 and 18 months respectively. Initial treatment consisted of left hemi-mandibulectomy and left neck dissection and fibula free-flap. All lymph nodes were tumor free. More likely the original maxillary tumor was a chondroblastic osteosarcoma. The left mandibular tumor was diagnosed as an osteosarcoma of higher grade than the original maxillary tumor.

Tumor recurrence necessitated a second vascularized fibula flap

Metachronus osteosarcomas of the long bones appear more often in the axial skeleton and implies multiple lesions appearing at different times, each one behaving clinically as a primary lesion. It usually presents with a painless swelling, mucosal ulceration and paraesthesia.

The pathogenesis of the tumor is unknown as it is unclear whether the lesions represent independent primary tumors or metastatic disease.

Nasal obstruction as the first symptom in a patient with a calcifying epithelial odontogenic tumour (CEOT).

Dent Update 2009 Jul-Aug;36(6):350-2, 355

Division of Maxillofacial, Diagnostic, Medical and Surgical Sciences, UCL Eastman Dental Institute, London, UK.

Calcifying epithelial odontogenic tumor (CEOT), known as Pindborg tumor, is a rare, benign odontogenic neoplasm. A female patient with an intra-osseous CEOT in the maxilla presented with unilateral nasal obstruction and progressive difficulty in breathing for over 18 months. Clinical symptoms correlated with complete left maxillary sinus radiopacity on CT. Total tumor clearance was achieved in 2006 with left maxillectomy within a safe margin.

There was no tumor recurrence. Dental clinicians incidentally locate such tumors, during investigation of missing or non-erupted maxillary teeth, ie canines, and they should be alerted by any unilateral nasal obstruction symptoms. Diagnostic features and treatment options of the tumor are discussed in relation to the histological typing.
The importance of clinical and radiographic investigation is essential for overall tumor removal.

A novel distractor for a free flap reconstructed mandible

J Craniomaxillofac Surg 2008;36(Suppl1):S44. [O.172]

Journal of Craniomaxillofacial Surgery

   


A 42-year old man had his left mandible reconstructed with an osseo-cutaneous fibular flap following wide resection of a high-grade osteosarcoma. A reconstruction plate was used for fixation of the fibular bone. There was vertical deficiency between the neo-mandible and the maxillary plane. To overcome this, the fibular bone segment was vertically distracted following a latency period of 5 days.  

The rate of distraction was 0.75 mm/day (2 x 0.375mm) twice daily. Distraction was applied for 12 days and the distractor was left in place for another 16 weeks for bone consolidation. Vertical distraction of the fibular flap was practically uneventful. The overall increase of vertical height was 9 mm.

Immediate functional loading of single-tooth TiO2 grit-blasted implant restoration. A controlled prospective study in a porcine model. Part II: Histology and histomorphometry.

Clin Implant Dent Relat Res 2007 Dec;9(4):207-16

University College London Eastman Dental Institute, 256 Gray's Inn Road, London, England, UK.

  There is a fast-moving shift from delayed to immediate implant loading. The hypothesis to be tested was that bone reactions adjacent to single TiO2-microthreaded implants exposed to immediate masticatory loading for 10 weeks after placement would modulate osseointegration.

Materials And Methods: Cylindrical- and tapered-designed implants (Astra Tech AB, Mölndal, Sweden) replaced first and third mandibular premolars respectively in 12 animals. The animals were allocated into two groups based on soft and hard diet feeding. Each animal received, at random positions, four different masticatory loading conditions: implant with either (1) a cover screw only, (2) a healing abutment, (3) an implant with a crown without occlusal contact, or (4) an implant with a crown in contact.
Results: Histomorphometry showed that there were no statistically significant differences in bone-implant contact (BIC), bone mass inside/outside of the threads and soft tissue ingrowth ratio for all the implants at 10 weeks after placement irrespective of masticatory loading condition. Bone loss showed a trend of progressive increase for implants with a healing abutment toward implants with occlusal contact.
Conclusions: The results of this study rejected the hypothesis and could be explained by the fact that grit-blasted acid-etched implants were already placed in dense bone.
