1/33. Proximal symphalangism and congenital conductive hearing loss: otologic aspects.OBJECTIVE: Results of stapedectomy are reported in a Belgian 26-year-old woman and two Dutch brothers having the proximal symphalangism syndrome (McKusick 18580). STUDY DESIGN: case reports are presented. A review of the results of ear surgery for congenital conductive hearing loss in this syndrome is given. SETTING: The Belgian patient was treated in a general hospital. The Dutch patients were treated in a university hospital, which was a tertiary referral center. patients: patients were referred to have an evaluation of their hearing impairment. INTERVENTION: Based on the syndromal diagnosis and based on routine audiometric tests, a congenital ossicular fixation was considered to be the cause of the hearing loss. By exploratory tympanotomies, this was confirmed. Reconstructive procedures including stapedotomy were performed. MAIN OUTCOME MEASURES/RESULTS: Long-term audiometric data are presented to evaluate the outcome of the surgical interventions. CONCLUSIONS: Congenital stapes ankylosis eventually combined with a congenital fixation of the short process of the incus in the fossa incudis, causing the congenital conductive hearing loss. Surgical intervention is very successful in most reported cases, but negative side effects are incidentally found as well.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |

3/33. A case report of a vital replanted tooth with unfavourable extra-alveolar condition: a 10-year follow-up.This case report describes the survival of a maxillary left central incisor after an avulsion injury under unfavourable extra-alveolar condition, when the patient was 9 years old. At subsequent clinical follow-ups, the tooth maintained vitality 10 years after the injury. There was sign of gradual obliteration of the root canal space. Concomitantly, the replanted tooth manifested typical characteristics of ankylosis with minimally detectable resorption complication.- - - - - - - - - - ranking = 42.015572356808keywords = alveolar (Clic here for more details about this article) |
4/33. The surgical treatment of heterotopic ossification at the elbow following long-term coma.Nine cases of heterotopic ossification at the elbow in seven patients who had a cerebral injury and prolonged coma were treated by excision of the extra-articular bone bridge from the humerus to the ulna. The bridge was either anterior or posterior, and did not involve the radius. The articular cartilage in all elbows showed no significant evidence of degeneration in spite of the prolonged immobility of the joints during the period of coma. Two of the patients also had resection of heterotopic bone about the hip joint which resulted in rapid reformation of bone. In all patients there was restoration of satisfactory function in the elbow operated on without reformation of bone. Follow-up was from ten months to 8.7 years.- - - - - - - - - - ranking = 21.827046545427keywords = ridge (Clic here for more details about this article) |
5/33. Preserved costal cartilage homograft application for the treatment of temporomandibular joint ankylosis.ankylosis of the temporomandibular joint has been a daunting problem in oral and maxillofacial surgery. Condylectomy with gap arthroplasty is the basic technique for treatment of the fully grown patient. In the past, reconstruction has primarily been accomplished with alloplastic materials or with autogenous tissue harvested from the patient. joints reconstructed with alloplastic materials have been subject to complications such as acute infection and chronic inflammatory problems as a result of foreign-body reaction with the immune system. Biologic reconstruction with autogenous materials does expose the patient to the risk of complications at the donor site. In the last 4 years, we have treated seven patients between the ages of 20 and 42 years who had complete temporomandibular joint ankylosis. In each patient, the affected joint was exposed through an extended preauricular incision. The ankylosed mandibular condyle with the surrounding abnormal bone, together with the coronoid process, was resected and removed. The ankylosed area was resected until an improvement of at least 15 mm in the interincisal opening distance was obtained. A solvent-preserved homologous cartilage graft was sculpted according to the size and shape of the gap and was then placed in it as interpositional material. Physical therapy, including active and passive mouth-opening exercises, began on the second postoperative day and continued for 6 months. patients were observed for 6 months to 4 years. During this period, no major complications were noted, and satisfactory results were obtained. The initial mean interincisal opening distance was 15.2 mm after surgery, and the final mean interincisal opening distance was 32 mm after completion of physiotherapy. No recurrence was seen during the 4 years of follow-up. This technique seems to be an effective, time-saving, and simple alternative to other methods of joint reconstruction in adults who have fairly extensive ankylosis of the temporomandibular joint. In this article, a description of the surgical technique, a review of all cases, and recommendations for the use of this type of graft material are discussed. Our clinical experience over the past 4 years with the use of preserved homologous costal cartilage grafts as interpositional material has been encouraging.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
6/33. Decoronation of an ankylosed tooth for preservation of alveolar bone prior to implant placement.A 12-year-old patient sustained avulsions of both permanent maxillary central incisors. Subsequently, both teeth developed replacement resorption. The left incisor was extracted alio loco. The right incisor was treated by decoronation (removal of crown and pulp, but preservation of the root substance). Comparison of both sites demonstrated complete preservation of the height and width of the alveolar bone at the decoronation site, whereas the tooth extraction site showed considerable bone loss. In addition, some vertical bone apposition was found on top of the decoronated root. Decoronation is a simple and safe surgical procedure for preservation of alveolar bone prior to implant placement. It must be considered as a treatment option for teeth affected by replacement resorption if tooth transplantation is not feasible.- - - - - - - - - - ranking = 50.418686828169keywords = alveolar (Clic here for more details about this article) |
7/33. Transpalatal excision of the odontoid process.A patient with platybasia of the skull and temporomandibular joint ankylosis is presented. Relief of brain stem compression by the impingement of the odontoid through a soft, hypoplastic clivus was done by first doing a mandibular condylectomy to open the mouth. A transoral-transpharyngeal route was then employed to excise the odontoid process.- - - - - - - - - - ranking = 5keywords = process (Clic here for more details about this article) |
8/33. Fibrous ankylosis after distraction osteogenesis of a costochondral neomandible in a patient with grade III hemifacial microsomia.Distraction osteogenesis has recently become a mainstay for treatment of craniofacial syndromes with mandibular hypoplasia. This article presents the difficult case of a patient with a previous costochondral rib graft who underwent mandibular distraction and developed a fibrous pseudoarthrosis at the distraction site. This was attributed in part to an associated temporomandibular joint ankylosis. Resorption of the pseudoarthrosis occurred once the distractor was removed. It appears that distraction osteogenesis of a mandible with an ankylosed temporomandibular joint can result in healing with a fibrous union, presumably because of movement at the distraction site when masticating. This can result in a pseudo "temporomandibular joint" at the distraction site. A temporomandibular joint arthroplasty was performed, followed by repeat distraction. We conclude that if there is an ankylosed temporomandibular joint or a stiff temporomandibular joint that may ankylose during the course of the distraction process, then a temporomandibular joint arthroplasty should be performed before or at the time the distractor is placed.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
9/33. An unusual case of sub-condylar bilateral fracture and bilateral post-traumatic temporomandibular ankylosis.A case of bilateral sub-condylar fracture with wide stump dislocation associated with a central facial trauma, fracture-intrusion of the rhino-orbital-maxillary complex and a parasymphyseal mandibular fracture, is reported. After surgery and inter-maxillary fixation an unusual temporo-mandibular ankylosis developed. Maximum mouth opening, lateral and protrusive movements were severely limited. Surgical treatment of ankylosis was requested and performed. The originality of this case lies in the atypical lateral dislocation of condylar neck fractured stumps to the zygomatic arches and in the later appearance of ankylosis between the glenoid fossa, zygomatic arch, condylar neck stump, and the condylar process displaced anteromedially. The ankylosed blocks were resected, displaced condyles were also removed due to the strong adhesion with the ankylotic tissue and the lack of any anatomical continuity or connection with the glenoid fossa. Functional therapy allowed the resolution of the functional limitation.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
10/33. Jacob's disease: report of two cases and review of the literature.Jacob's disease is a rare condition consisting of new joint formation between the coronoid process of the mandible and the inner aspect of the zygomatic arch. Strictly speaking, it was first described by the French anatomist Oscar Jacob in 1899, although in 1853 von Langenbeck had described coronoid process hyperplasia. The pathogenesis of both conditions remains unknown. In this paper we present two new cases and a complete review of the literature on Jacob's disease, of which we have found only 12 cases. Due to the low prevalence of this condition, its diagnosis is not straight forward.- - - - - - - - - - ranking = 2keywords = process (Clic here for more details about this article) |
