Factors associated with long-term complications after repair of mandibular fractures

Educational Objective: At the conclusion of this paper, the participants should be able to identify, compare, and discuss the natural history of complications of mandible fractures and repair. Objectives: To analyze factors affecting the incidence of long‐term complications after the repair of mandible fractures. To determine whether the use of antibiotics at any time in the course of treatment impacted the development of complications. Study Design: Retrospective medical record review. Methods: Medical records for patients with mandibular fractures treated surgically over a 5 year period were reviewed for demographics, history of substance abuse, etiology, location of fracture, any associated facial injury, type and timing of repair, pre‐, peri‐, and postoperative antibiotic treatment, length of hospitalization, and lag time to repair. The development of infectious and other complications after surgery, specifically, the development of abscesses, fistulae, mal/nonunion, hardware exposure, or extrusion, were recorded. Results: Of 273 subjects, 56 fractures were repaired using open reduction internal fixation (ORIF) alone, 112 mandibulomaxillary fixation (MMF), and 105 with a combination of MMF and ORIF. Eighteen (6.6%) patients developed an infectious or related long‐term complication. These included abscess (n = 4), infected hardware (n = 1), mal/nonunion (n = 8), and hardware exposure/extrusion (n = 9). Smoking and alcohol abuse (P = .021) and the use of plating techniques (P = .04) correlated with a higher incidence of long‐term complications. Patient age, sex, location and etiology of fracture, associated facial injury, lag time to repair, length of hospitalization, and the use of antibiotics at any time after injury or repair were unrelated to the development of complications. Conclusions: The development of infection, nonunion, and related complications after the repair of mandibular fractures correlates with a history of tobacco and alcohol use and ORIF of multiple fractures, but there were no statistically significant relationships to patient demographics, fracture site, lag time to repair, length of hospitalization, or the use of antibiotics. In this series, antibiotic therapy appears to have had no impact on the development of postoperative complications.     

Comparison of complications following frontal sinus fractures managed with exploration with or without obliteration over 10 years

Two hundred twelve patients were treated for facial or skull trauma at the West Virginia University Hospital between the years 1977 and 1987. Sixty-six of these patients had frontal sinus or nasofrontal duct trauma. Follow-up information was obtained on 64 of these patients through clinic visits, chart review, questionnaires to patients and physicians, and telephone calls to the patients. Follow-up greater than 1 year was obtained on 52 patients. Sixty-four patients were managed either with a frontal sinus obliteration or with an open exploratory procedure. The incidence of complications occurring in the past 10 years after each of these procedures is compared. Because the indications for each procedure vary somewhat, data is presented on fracture etiology, associated injuries, specific fracture location, fracture displacement, severity of injury, and associated cerebrospinal fluid leaks.     

Acute mastoiditis in children, a retrospective analysis about a period of 25 years

BACKGROUND: During the last years the classical signs of the acute mastoiditis have changed. Aim of the following study was to examine the change of symptoms as well as the change of incidence. METHODS/PATIENTS: The records of 113 children who received mastoid surgery due to acute mastoiditis were retrospectively investigated. Data covered a regional group of patients during a period of 25 years (1979 - 2003). RESULTS: Considering the drop of the birthrate from 1991 in the East German countries, there was a significant increase of the incidence of acute mastoiditis. The patients had a mean age of 2,5 years. The classical symptoms like "retroauricular swelling, tenderness and protrusion of the auricle" were only noted by 47 children (41.6 %). Preoperative complications appeared as facial palsy, abscess and septic lateral sinus thrombosis in 11 children. Bacterial cultures, taken during surgery yielded in 55.7 % Streptococcus pneumoniae. The therapy contained a surgical intervention combined with antibiotics. CONCLUSIONS: An early surgical treatment by mastoidectomy or antrotomy supported by antibiotics represents the safest method to avoid complications.     

Quantitative evaluation of thermosensitivity in patients with mandibular fractures]

AIM: The temperature and pain thresholds of 30 patients with mandibular fractures were evaluated with a specially developed measuring device in a prospective study to examine neurosensory disturbances of the inferior alveolar nerve (IAN). PATIENTS AND METHODS: Measurements in 30 patients with 45 mandibular fractures were done before, immediately after, and over the course of half a year after operation. Outcomes of the thermosensitivity measurement (TSM) were compared to the results of the two point discrimination (2-PD) test, sharp/blunt test (SBT), and questioning the patients about their subjective feelings (SF). RESULTS: Post-traumatically, neurosensory testing revealed up to 2.8 degrees C (mean) increased thresholds as compared with the intact side. By contrast, post operative diagnostics clearly revealed up to 8.1 degrees C (mean) increased thresholds. Compared with the clinical sensory tests, the post-therapeutic (3-6 months postoperative) measurements with the TSM device proved a resensitization and threshold decrease by up to 3 degrees C. We found more exact and reproducible results of the TSM in comparison to those of the 2-PD and SBT for the evaluation of sensory disturbances of the IAN. Close agreements between the results of the TSM and the SF could be detected. CONCLUSION: Because of its sensitivity and accuracy in the quantitative detection of temperature and pain thresholds, the TSM is particularly suitable for evaluating neurosensory deficits and monitoring their progression.     

Pierre Robin sequence: postoperative complications following cleft palate surgery. A retrospective study covering 25 years]

BACKGROUND: In a 25-year retrospective review of 1976-2000, the postoperative course after cleft palate surgery and pharyngeal flap surgery in 87 children with Pierre Robin sequence was studied. PATIENTS AND METHODS: The study comprised 114 interventions with 87 primary palatoplasties; 17 patients required palatal fistulae repair and 10 children were treated with secondary pharyngoplasty procedures. All children were divided into three postnatal risk groups according to the severity of their symptoms at birth and in the course of the early months of life. RESULTS: A direct correlation was seen between the incidence of early postnatal difficulties and the postoperative obstructive complications after cleft palate surgery and pharyngeal flap surgery. Thus, children experiencing obstructive problems at birth (high postnatal risk group) displayed more severe complications at the time after cleft palate repair. In children undergoing pharyngeal flap surgery not only early postoperative obstruction but also late obstructive sleep apnea can occur.     

10 years of maxillofacial traumatology in a hospital center]

The authors describe 315 cases of total maxillo-facial fracture and the conclusions to be drawn from them: --Endobuccal and orthopaedic surgical treatment under general anaesthetic, the osteosynthetic material being perfectly well tolerated: less than 3% having to be removed. --Treatment requiring a careful pre-operative radio-clinical assessment which can never be adequately carried out in an emergency, therefore treatment is delayed (5th and 8th days) except in cases of special emergency (wounds). --Delayed sequelae, bearing in mind the often spectacular lesions, are relatively rare.     

Nasal washing with Physiomer ... 10 years later: 1988-1998]

The authors present the story of Physiomer. It began in 1988 in Goemar's 'Laboratory of the Sea', with an original idea of making a product manufactured from sea water and transforming it into an isotonic solution, while preserving all the elements of natural sea water, specially the trace elements and the alkaline PH. Scientific analysis has shown that the chemical composition of the product is true to the original, and that it has a positive action on cellular growth in respiratory tract mucosa in experimental culture, and it is very well tolerated. Clinical tests using nasal washings have confirmed beneficial action on the nasal and sinus mucosa in medical disease and after surgery. Tests have been carried out on 410 cases, 344 of which were treated with Physiomer, and on 199 cases after surgery on the nose or sinuses. Physiomer nasal washings have proved their value. It now remains for all the potential qualities of sea water to be demonstrated, using other preparations or other combinations.     

CO2 laser in otolaryngology-head and neck surgery: a retrospective analysis of complications

A retrospective review was conducted of all patients undergoing CO2 laser surgery by members of the Department of Otolaryngology-Head and Neck Surgery at Northwestern University Medical School from January 1, 1980 through December 31, 1981; 204 cases were identified and all are included in this report. Early in our department's experience with laser surgery, an endotracheal tube fire occurred. This incident precipitated a departmental review of complications associated with the use of the CO2 laser and resulted in the formulation of a laser safety protocol. All patients in this group were treated under the directives of this protocol; the operative complication rate was low. This retrospective analysis of complications associated with the use of the CO2 laser under a strictly applied protocol demonstrates the relative safety associated with judicious use of this instrument.     

Management of mandibular fractures using biphasic pins and mandibular splints

Often the otolaryngologist is asked to manage the patient with facial trauma. Mandibular fractures make up 20 to 39% of all facial trauma cases, and thus necessitate a diversified and complete set of management tools. We have selected two seldom discussed modes of therapy for the complicated jaw fracture to present in this paper: 1. external fixation or Joe-Morrison Hall biphasic pins, and 2. mandibular dental appliances — splints. The advantage of the biphasic pin apparatus is that the fracture can be repaired and stabilized at a point remote from the infected fracture site. The high risk patient, endentulous patient, and patients with fractures from gunshot wounds all prove to be more easily managed by using the external appliances. The splint technique eliminates medial or lingual tip rotation and resultant postoperative malocclusion. Endentulous patients, pediatric patients, and those with multple facial trauma also benefit from this procedure.     

Postoperative complications in cochlear implants: a retrospective analysis of 438 consecutive cases

Our objective is to determine the complication rate in a population of infants, children, adolescents and adults, from a University Hospital Cochlear Implant program and to discuss their causes and treatments. The methods include a retrospective study of 438 consecutive patients in a tertiary referral centre, the Audiology Department of the University Hospital of Ferrara. All patients receiving cochlear implants, between 1 January 2003 and 31 December 2009, have been included. All complications and treatments were systematically reviewed with an average duration of follow-up of 46 months (range 10–84 months). The results reveal that the overall rate of complications in our group was 9.1% (40 of 438), and most of them were minor. Wound swelling and infections represent the most common complication occurred. There were no cases of transient or permanent facial palsy following surgery, and also we did not register any case of postsurgical meningitis. Thirteen patients (3.0%) underwent explantation followed by reimplantation. In conclusion, we find that Cochlear implantation is a safe low-morbility technique with a relatively low complication rate in the presented population.

Isolated fractures of the orbital floor. Conclusions of a retrospective study of 85 cases]

We present a retrospective study of 85 patients presenting an isolated orbital floor fracture between 1993 and 1997; 79 of them (93%) were operated via a subciliary or transconjunctival approach. Surgical procedure included autologous graft or biomaterial (coral, polydioxanone) depending on the cases. The study was focused on clinical data (concerning diplopia, enophthalmia and sensorial disturbances) which were recorded pre- and post-operatively. RESULTS: 58 patients (68%) had a pre-operative diplopia, and 9 (11%) had a persistent post-operative diplopia: all of these patients were operated more than 8 days after trauma; no post-operative diplopia occurred without pre-operative diplopia; 8 patients (9%) presented a pre-op enophthalmia: all of them came more than 10 days after the trauma; a perfect symmetry was obtained post-operatively in only one of these 8 patients; no enophthalmia occurred in patients without pre-op enophthalmia; sensorial disturbances were seen pre-operatively in 27 patients (32%) and post-operatively in 17 (20%); no correlation was found with the timing or the procedure of the surgery. COMMENTS: The interest of an early diagnosis and treatment is confirmed, in order to avoid late functional (diplopia) or esthetic (enophthalmos) disturbances. Thus it seems necessary to obtain a computed tomography for any orbital trauma as conventional radiography can be less sensitive. Concerning the surgical procedure, resorbable biomaterials seem to be very well tolerated and easy to use. Autologous bone grafts always lead to a certain degree of morbidity without real advantage. The best way seems to be the trans-conjonctival approach, but subciliary incisions can also be used in these cases. The most important remaining problem to solve is probably focused on sensorial disturbances: their incidence is high and there is a high rate of sequels: further studies are obviously necessary to improve the knowledge of etiopathogenic factors and determine the best therapeutic attitude.     

Orbit complications of sinusitis in adults. Our cases during 10 years

The sinusites orbital complications usually associated to ethmoidites are rare in the childhood. We present a revision of 14 adults patients (10 males and 4 females) 18 to 61 years old. Seven presented a preseptal cellulitis, two had a subperiostial abscess and five an orbitary cellulitis in accordance with the Candler classification. We analyse the personal previous history, the clinical data, complementary tests and treatments (medical and surgical) evolution and hospital stay. We realise a literature revision about this subject.     

Augmented fixation of mandibular fractures with a threaded Kirschner wire

The maxillofacial surgeon uses a variety of techniques when treating mandibular fractures. The aim of treatment is to restore structure and function while minimizing morbidity. This requires adequate anatomic reduction and immobilization. The surgeon's choice of techniques should be safe, simple, economic, and effective. In this article, we discuss a previously described, yet little known, technique that fulfilled these criteria. The technique of augmented fixation of mandibular fractures using a threaded basal Kirschner wire was successfully used in seven patients. It offered the distinct advantage of rigid basal fixation that augmented interosseous and maxillomandibular fixation techniques. It was especially effective in stabilizing and promoting bone healing in unfavorable comminuted parasymphyseal fractures. Its ease and rapidity of application from readily available materials made it an effective alternate to elaborate techniques such as compression-plating systems.
