[Replantation of traumatic amputated ears by Mladick procedure: 6 cases].

UNLABELLED: Traumatic ear amputations are relatively rare. Whenever possible, ear reimplantation should be attempted, however the choice of the surgical procedure must be judicious. PATIENTS AND METHODS: We present 6 cases of partial ear amputation treated by the pocket technique described by Mladick. The series comprises 5 partial amputations severing less than half of the auricule and 1 subtotal amputation preserving the ear lobule. RESULTS: Necrosis of the avulsed fragment occurred in the only case of subtotal amputation. In the 5 other cases the revascularisation of the severed part was successful. Morphological results are often very good when the ear is freed from the pocket before 4 weeks. Beyond this delay skin grafting is necessary and inaesthetic scar retraction occurs. CONCLUSION: The success rate depends on the size and the degree of contusion of the amputated ear. We recommend the Mladick's procedure for reimplantation of fragments less than 1/2 of the auricle with favorable tissue condition. We believe that other procedures described in the literature could offer a good alternative for amputations exceeding half of the ear pavilion.

[Facial injuries treated in the Grenoble University Hospital. Epidemiological analysis of 961 patients managed in one year].

INTRODUCTION: The purpose of this study was to determine the types of facial injuries treated in a one-year in a maxillo-facial unit operating in a mountainous region. METHODS: All patients admitted to the Grenoble University Hospital maxillo-facial unit for a one year period were studied. We noted cause of trauma, age, sex, type and location of fracture, type of soft tissue injury, time between trauma and surgery. RESULTS: A total of 994 patients presenting maxillo-facial trauma underwent surgery over one year; 30% of the unit's maxillo-facial surgical activity. On average, 80 patients were treated for maxillo-facial trauma per month, with a peak of 97 facial injuries in July; 65.6% were hospitalized in the maxillo-facial unit; 25,4% of the injured were aged between 21 and 30 years. Sex-ratio was 2.7M/1F. The most frequent cause was sports injuries (25.8%) followed, in decreasing order, by traffic injuries (23.1%), home injuries (17.6%), fight injuries (3.4%), work injuries (3.4%) and dog bites (3.2%). 10.5% of the injuries occurred in a mountainous setting and 40.7% were sports injuries, 95% of which during practice of winter's sports. Injuries included facial fractures (65.5%) with or without soft tissue damage, and soft tissue injuries only (34.5%); 33.6% of the patients had other lesions of the body. 67.2% underwent surgery within the first 24 hours and 86.9% before the fifth day. DISCUSSION: Sports accidents are the leading cause of facial trauma in the mountainous regions. Most facial injuries result from ski, surf and other winter sports accidents. Most of the victims were given surgical care within the first 24 hours following the accident.

[Dacryo-cysto-rhinostomy via an external approach].

The dacryo-cysto-rhinostomy via the external approach is indicated for obstruction of the lacrymal duct. It consists in the creation of short-circuit between the lacrymal sac and the external nasal wall. The operation stages starts by paracanthal incision, the subperiosteal dissection stops anteriorly to the posterior insertion of the medial canthal ligament (to preserve lacrymal function). An ostectomy is performed between the maxillary bone and the unguis. A stomy is created by individualizing two mucosal flaps. The bicanaliculonasal intubation is systematic and maintained for 10 to 12 weeks.

[Fractures of the mandibular angle: factors predictive of infectious complications].

INTRODUCTION: Fractures of the mandible angle raise the risk of infectious complications. We searched for factors predictive of these complications. MATERIAL AND METHODS: We reviewed retrospective all cases of mandibular angle fracture treated during a 26-month period. We compared two groups: fractures with wisdom teeth and fractures without wisdom tooth. For each group we noted clinical and radiological characteristics of the fractures and infectious complications. RESULTS: The series included 72 mandibular angle fractures, 30 with a wisdom tooth against 42 without. Most of the patients were treated within 2 days, generally using mini-plate screw fixation. In the wisdom tooth group, 16.6% of patients developed infectious complications versus 9.5% in the without wisdom tooth group. All patients of the wisdom tooth group presented a potentially infectious focus on the preoperative x-rays. For without wisdom tooth group, irregular follow-up was found to be the only risk factor. DISCUSSION: The angular localization increases the risk of infectious complications especially if the wisdom tooth is in the fracture. We propose a decision tree to determine when to preserve or not the wisdom tooth.

[The bony deficit in cleft lip and palate: review of procedures. Experience with the tibial periosteal graft].

Surgeons have long been preoccupied with continuity of the bone in the repair of cleft lips and palates. It is no longer necessary to demonstrate the deleterious effect of employing osteoplasty in a first stage procedure; very few practitioners still rely upon it. On the other hand, a great number of authors now advocate a bone graft as a secondary operation, although they have not been able as yet to reach a consensus on its timing, nor upon exactly what its objectives should be. An early bone graft, carried out at the time of the primary dentition, would have as its goal stabilization of the maxillary segments and prevention of relapse of the maxillary retrusion as the dentition becomes mixed. Any hopes that such an intervention would have a beneficial effect with regard to the area of the lateral incisors, which are usually malformed or absent, seem to us illusory. A secondary bone graft, undertaken during the mixed dentition before the eruption of the canines, when a maxillary bony deficit is present with accompanying alveolar insufficiency. We consider that a distinction between the areas of bone, the maxillary and the alveolar, is essential because a continuity of maxillary bone, a guarantee of skeletal stability, can be obtained in more than 70% of cases by perio-osteoplasty (a graft of tibial periosteum or gingivo-perio-osteoplasty). When this cannot be done, a massive bone graft will be needed at the close of orthopedic treatment. Continuity of alveolar bone, the guarantee of occlusal stability, can be obtained at the close of orthodontic treatment with the use of a provisional prosthesis followed by a permanent replacement after completion of gingival correction. We believe a graft to prepare for an implant in an area where scar tissue can be a problem would be risky especially since implants, in our opinion, do not provide the same stability to a dental arch that a fixed bridge affords.

[Bilateral cleft lip and palate. Anatomic and clinical characteristics and therapeutic results].

Treatment teams that conceive and nourish their ideas in a multi-disciplinary environment are best suited to elaborate therapeutic protocols. Their concepts should be based on consistent evaluation of their treatment results as documented by precise and reproducible records. In the wide array of maxillo-facial anatomical deformities presented clinically, bilateral cleft lips and palates are the rarest (20%), but they are also the most serious because of the inherent disconnection of maxillary structures that accompanies them and because of the grave disturbances they inflict on the development of the middle third of the face. Surgeons have devised an extraordinary gamut of protocols to correct these disorders and then abandoned them because of the problematical and ephemeral results they provided. The authors, after evaluating their own results, modified their therapeutic approach in 1994. They present their current protocol, which calls for an orthopedic phase carried out when the patient is 2 months old and two surgical phases when the patient is 3 and then 7 months old.

[Alveolar and hard palate repair by tibial periosteal graft in complete unilateral cleft lip and palate. Long-term follow-up of 51 cases].

PURPOSE OF THE STUDY: The purpose of this study was double: appreciate the osteogenic and growth capacities of the free tibial periosteal graft concerning the alveolar and hard palate repair in the complete unilateral cleft lip and palate, and evaluate long-term follow-up concerning maxillo-mandibular morphology and palatal air-tight. MATERIAL AND METHOD: This retrospective study concerns 51 patients, of more than 13 years of age, treated for complete unilateral cleft lip and palate. The treatment included a Skoog type cheiloplasty, a tibial periosteal graft between 4 and 6 months (as described by M. Stricker) and a staphyloraphy between 8 and 18 months. Our documentation was: figures, pictures and precise description of the initial cleft, dental casts, teleradiographies, dental panorams performed at different stages of treatment, orthodontic, orthophonic and otologic follow-up. Growth was evaluated using casts during the first 6 years then by profil teleradiographies after puberty. Ossification was evaluated quantitatively by CT scan in 18 patients. RESULTS: Results confirm an ossification of the periosteal graft in 72% of cases and the advantage of periosteal graft in palatal air-tight. 85% of cases show equilibrated squeletal growth with good occlusion, and 13.7% of cases needed deferral osteotomy. CONCLUSION: We propose a method for long-term cleft results evaluation, with the use of periosteal graft.

[Labial function].

Lips should be considered as a phylogenic summary for nasolabial and facial mask evolution. They're the centre point of facial morphogenesis. The progressive development of oral and facial functions is a specific human necessity: feeding, suction, oral competence, swallowing, language and mimics. Each discontinuity create function and anatomic failures. Each damage create facial unbalance.

[Development of lip reconstructive procedures].

The history of lip repair shows significant parallelism with the evaluation of ideas in plastic and reconstructive surgery. The first attempts were addressed mainly to full-thickness lower lip repair as the resulting labial incompetence was more handicapping. However, techniques and knowledge evolved rapidly to the modern state of the art. Almost all the procedures used today were already described in the early 20th century and their progress based on a profound knowledge of functional anatomy established the principles of labial sphincter dynamic repair by tissue redistribution.

[Tools available for the diagnosis of obstructive sleep apnea syndrome. Measurements for the evaluation of therapeutic efficacy].

Obstructive sleep apnea syndrome (OSAS) is characterized by the development of repeated episodes of pharyngeal collapse. Respiratory movements attempt to reopen the closed pharynx leading to resumption of ventilation associated with micro-arousals. Three kinds of measurements are needed to establish the diagnosis of OSAS: airflow (reduction or complete interruption), respiratory effort in response to increased airway resistance, micro-arousals associated with the end of the respiratory event. Classically, polysomnography was used to establish sleep architecture using electroencephalography, electromyography and electro-oculography. Air flow was measured by thermistors, chest and abdominal movements and oximetry were monitored. Other more accessible methods can also be used to establish reliable diagnosis. Measuring pulse transit time using ECG and oximeter sensors provide a semi-quantitative measurement of respiratory effort. Likewise, cardiovascular markers (heart rate, blood pressure, pulse time) can be used instead of electroencephalography to establish the arousal pattern. Cardiovascular markers are as sensitive and probably as specific as EEG for identifying micro-arousals. Measuring nasal pressure provides a much less invasive quantitative assessment of airflow than pneumotachography. The shape of the inspiratory signal is also an indirect marker of respiratory effort. These new tools can be used to characterize the three elementary abnormalities observed in OSAS: variations in airflow, increased respiratory effort, fragmented sleep, using a very simplified setting compared with classical techniques. Therapeutic monitoring of OSAS patients, particularly after surgery, should not be limited to physical examination known to lack sufficient sensitivity. It should also include simplified methods or complete polysomnography to obtain a precise measurement of residual respiratory events and sleep pattern after treatment.

[Surgery and obstructive sleep apnea syndrome: indications and precautions].

Surgery has long been a therapeutic option for obstructive sleep apnea syndrome (OSAS). The first procedures targeted the soft palate but results of isolated uvulo-palatopharyngoplasty (UPPP) were inconstant. A better understanding of the mechanisms involved in pharyngeal collapse incited interest in the role of the tongue and the retropharyngeal space. Surgical procedures were then developed for this level of the upper airways. There are a large number of possibilities. Excepting tracheostomy which court-circuits the collapsed zone, all the other procedures are designed to widen more or less one or more of the upper airway levels. The target can be the nose, the soft palate or the tongue, alone or in combinations. In all cases, the surgical alternative should be balanced against a non-invasive option: continuous positive pressure ventilation. The objective is to minimize the operative risks and sequelae while assuring success equivalent to positive pressure ventilation. It is important to note that sufficiently effective and permanent results have not been proven for any surgical technique, excepting tracheostomy and to a lesser degree bimaxillary advancement osteotomy, due to the lack of objective long-term rigorous evaluation. A considerable effort must be made in this domain.

[Mandibular growth, its environmental interactions].

A thorough knowledge of mandibular growth is necessary for proper comprehension of growth disorders and malformations affecting the lateral cranio-facial region. The growth mechanisms are complex and multifactorial, the mandible itself is subdivided into two heterogeneous and interdependent segments, as far as growth is concerned. These are the ramus and the corpus. The ramus is interacting with the middle cranial base through the TMJ and the temporo-pterygoid muscle belt. The mandibular body is interacting with the maxilla and the anterior cranial base. Its occlusal role is a function of the adaptive capacity of the alveolodental region.
