A retrospective analysis of the management and surgical treatment of orbital lesions: Outcomes and rationale.

The orbital cavity is a subject of interest for various specialists, and achieving optimal outcomes requires comprehensive, multidisciplinary management. This study aims to report 10 years of experience in the preoperative, surgical, and postoperative care of patients with orbital lesions, examining their clinical, radiological, and anatomopathological features and outcomes. A retrospective review of 125 patients who underwent surgical treatment for intraorbital masses between January 2012 and December 2021 was performed. Outcome measures included postoperative diplopia, exophthalmos, decimal visual acuity, eyeball position, ocular motility, operative time, complications, and aesthetic results. A total of 107 patients were included. All cases were discussed with a neuroradiologist to determine the best therapeutic approach based on preoperative imaging. Preoperative diplopia was linked to extraconal (p = 0.03) and anterior (p = 0.001) lesions, and exophthalmos and visual acuity deterioration were associated with intraconal (p = 0.02; p = 0.03) and retrobulbar (p = 0.001; p = 0.02) lesions. Complications (11.2%) included diplopia, worsened visual acuity, postoperative blepharoptosis, and postoperative ectropion. Of the patients, 80.4% reported an "excellent" aesthetic outcome. This study underscores the importance of a multidisciplinary approach based on a thorough analysis of preoperative imaging. Periorbital approaches tailored to the lesion's three-dimensional location enables safe access to most intraorbital lesions, resulting in minimal complications and good aesthetic results.

Maxillomandibular Transverse Osteodistraction: A Multidisciplinary Case Report with 30-Month Follow-Up.

AIM: To describe a multidisciplinary treatment to correct a severe II class malocclusion with reduced both maxillary and mandibular transverse dimensions and dental crowding. Case Report. A 17-year-old young woman presented with an increased overjet complaining chiefly of forwardly placed upper front teeth and unpleasant smile aesthetics. The patient facially exhibited a gently convex profile, severe mentalis strain on lip closure, and dark buccal corridors. The intraoral assessment indicates Class II molar relationship bilaterally, mandibular and maxillary anterior crowding, and narrow shape of upper and lower arches. The cephalometric evaluation of the lateral radiograph of the skull evidences a skeletal Class II with a reduction of lower face height. Based upon the diagnostic records and consultation with the patient, surgically assisted expansion of both arches using bone-borne distractors, comprehensive orthodontic treatment, and combined jaw surgery was planned. RESULTS: This approach permitted achieving most of the desired objectives in approximately 30 months. The follow-up records 30 months after treatment conclusion showed a stable occlusion. No complications were clinically and radiographically noticeable during the follow-up.

Diagnosis and treatment of retrobulbar haematomas following blunt orbital trauma: a description of eight cases.

Retrobulbar haematoma following blunt orbital trauma is a rare, but potentially serious, complication, since it can evolve rapidly from visual impairment to permanent loss of vision. This sight-threatening situation most commonly arises from orbital bleeding accompanying undisplaced fractures of the orbital walls, an event that increases the pressure inside the orbit and results in vascular damage to the optic nerve. The clinical presentation includes pain, exophthalmos with proptosis, and internal ophthalmoplegia, with impairment or loss of the pupillary reflex. A thin-layer orbital CT scan is an essential diagnostic aid. Any delay between the onset of symptoms and treatment can have a significant effect on functional recovery. Therapy is based on orbital decompression, via different surgical approaches, with the intention of reducing the pressure on the nerve and vascular structures inside the orbit. This paper presents eight cases of retrobulbar haematoma and their follow-up, in detail.

Analysis of 158 frontal sinus fractures: current surgical management and complications.

A retrospective analysis is presented of 158 patients who sustained frontal sinus fractures and were subsequently treated in the Division of Maxillofacial Surgery, University of Turin, from 1987 to 1998. The fractures were subdivided according to involvement of anterior and posterior walls, and of the nasofrontal duct. While treatment involving only the anterior wall is well standardized and without complications, management of anterior plus posterior wall fractures or involving the nasofrontal duct is still controversial. In dislocated posterior wall fractures, cranialization and obliteration of the remaining dead space and of the nasofrontal ducts using bone grafts, combined with the use of a pericranium flap, allow separation of the nasal cavity from the anterior cranial fossa, preventing ascending infections and thus reducing the rate of complications. When the fracture involves the nasofrontal duct with the posterior wall substantially intact, it is better to re-establish patency of the nasofrontal duct with a drainage tube and preserve the function of the sinus. A protocol used in the management of each group of fractures, clinical and radiological results, timing of operation, surgical procedures, outcomes, and long-term complications are all discussed.

Maxillofacial trauma in the elderly.

PURPOSE: This article gives a general description of the incidence, causes, and complexity of maxillofacial fractures in the elderly and discusses whether modification is required in assessment, surgical indications, and techniques in such cases. PATIENTS AND METHODS: A retrospective clinical and radiologic study evaluated 222 patients older than 60 years of age (mean age, 70.3) hospitalized with maxillofacial trauma over the period 1987 to 1996 in the Division of Maxillofacial Surgery, University of Turin. The patients were classified according to the following parameters: age, cause of injury, site of trauma, presence of associated fractures, pertinent medical history, type of treatment, length of hospitalization, and complications. The data were compared with those from a control group consisting of 178 adult patients younger than 60 years of age. RESULTS: The presence of a preexisting systemic pathologic condition was the most important factor in determining hospitalization time, which was greater than in the control group. In 89 patients (40.1%), no treatment was considered necessary, whereas 133 patients (59.9%) were treated by surgery. In 115 patients (86.5%), the fractures were treated by open reduction and internal fixation, whereas closed reduction was used in 18 patients (13.5%). There were complications with six patients (2.7%), and one died in the hospital. CONCLUSIONS: The findings of this study suggest that surgical intervention is less frequently indicated in facial trauma of the elderly because of physiologic, psychologic, and social changes brought on by the aging process. The principles of treatment, the results, and the complications do not differ greatly in this group when compared with the normal adult population.

Maxillofacial fractures following airbag deployment.

Maxillofacial fractures and associated lesions following airbag deployment were studied in six patients who suffered frontal or fronto-lateral car crashes. Installation of airbags in motor vehicles has reduced the morbidity and the mortality following motor vehicle accidents, but the appearance of new types of trauma directly related to airbag deployment raise questions about the potential danger of these devices when used improperly. The results of this limited study suggest that airbag injuries can be aggravated if: (1) seat belts are not worn; and (2) if the driver's chest is too close to the steering wheel as can easily happen with small people (in our study, two women). There needs to be a way of disconnecting the system.

[Actinomycosis of the tongue. Report of two cases and review of the literature]. / Actinomicosi della lingua. Descrizione di due casi e revisione della letteratura.

Actinomycosis of the tongue is a rare form of infection whose initial clinical manifestation is a submucosal swelling that may mimic both benign and malignant neoplasias. Two cases are, presented and their clinical features and diagnostic criteria are discussed in the light of twelve cases drawn from the literature. Infection in the tongue is rare, though perhaps underestimated. It is generally located on the anterior two thirds laterally to the median sulcus, and presents as a moderately painful nodule set deep in the extrinsic and intrinsic muscles and poorly mobile on the adjacent planes. In a few weeks the lesion increases in size and painfulness with consequent loss of function in the absence of diagnosis and appropriate antibiotic management. Both our patients, in fact, presented with deep lesions and no apparent involvement of the mucosa, and were investigated by means of fine-needle aspiration biopsy (FNAB). The aspirated material was used to prepare both routine smears and cell blocks embedded in paraffin. The pathological material provided by this combination of methods proved quantitatively and qualitatively sufficient for the definitive diagnosis of actinomycosis in both cases.

Hyperplasia of the mandibular coronoid process: long-term follow-up after coronoidotomy.

The aim of this study was to evaluate long-term results of treatment by intraoral coronoidotomy and prolonged physiotherapy in five patients with mandibular coronoid process hyperplasia. Five consecutive cases of coronoid process hyperplasia were studied (two unilateral and three bilateral) at the Department of Maxillo-facial Surgery of the University of Turin during the period 1985-1990. All patients were treated by intraoral coronoidotomy and given physiotherapy from the third postoperative day. This continued for an entire year. A clinical and radiological follow-up (average 39.4 months), in three cases over a 5-year period, was completed. Three months after the operation, all patients had achieved satisfactory improvement in mandibular interincisal opening. The mean value for mouth opening at the end of follow-up was 42 mm. Radiographic follow-up showed the presence of a coronoid process almost the size of the original, apparently united with the mandibular ascending ramus, with moderate dislocation and inclination posterior to the body of the zygomatic bone. The results of this study indicate that treatment of coronoid process hyperplasia by intraoral coronoidotomy, when combined with prolonged postoperative physiotherapy, gives satisfactory and stable long-term results in the correction of coronoid-malar interference.

Rigid fixation with teeth in the line of mandibular fractures.

The treatment results and the incidence of complications were evaluated retrospectively in a group of 68 patients. They all had mandibular fractures with a tooth in the line of fracture and were treated using miniplates for fixation. The follow up ranged from 1 to 6 years (mean 2.6 years) and 90 fracture sites were involved. Results showed that the incidence of complications when the tooth was extracted was higher (3/12) than when it was left in place (8/78). With regard to both healing of the fracture and fate of the tooth in the line of fracture, it is recommended to retain teeth in the line of fracture, unless there is an absolute indication for extraction. It is advisable to monitor the vitality of teeth adjacent to the fracture line for at least one year.

[Primary reconstruction of the anterior sublingual sulcus with a nasolabial flap after the resection of a malignant neoplasm]. / Ricostruzione primaria della pelvi sublinguale anteriore con lembo nasogenieno dopo resezione di neoplasia maligna.

The reconstruction of the loss of substance from the oral floor following demolitive cancer surgery aims to guarantee adequate tongue movement and the consequent preservation of phonatory and swallowing functions, as well as the possibility of using prosthetic rehabilitation. Large defects are resolved using musculocutaneous or free vascularised flaps, whereas smaller defects may be closed by first intention using alveolo-lingual suture. There are a number of drawbacks to this method: occurrence of fistulas immediately after surgery and secondary ankyloglossia. It is then necessary to resort to a second operation using dermoepidermic graft and plastic surgery of the oral floor to liberate the tongue. These problems may be resolved using a nasolabial flap. The flap can be prepared using either an upper or lower peduncle, it is relatively simple to perform and does not significantly prolong operating times. The contemporary dissection of the neck with ligature of the facial artery does not in our experience significantly influence flap vascularisation. The main drawback is the limited size of the flap (on average it is 6-7 cm long with a maximum width of 3-4 cm at the base. The upper edge is equally placed 7-10 mm from the medial side). The flap must be sufficiently thick to ensure an adequate blood supply to subcutaneous tissue, but the dissection plane must be sufficiently near the surface to preserve the facial nerve. It is important to prepare the graft bed so as to avoid creating tension after suture.(ABSTRACT TRUNCATED AT 250 WORDS)

[A clinical evaluation of the outcome of a bone graft from the iliac crest]. / Valutazione clinica degli esiti di prelievo osseo da cresta iliaca.

The paper examine 40 cases of bone graft from the iliac crest used in maxillo-facial surgery. The immediate and late complications included pain with resulting difficulty of walking and, less frequently, hematoma, sensitivity disorders and dehiscence of the wound. Late complications were most frequently related to esthetic problems as well as a negligible number of persistent cases of difficult walking and neurological deficiencies. The results obtained were comparable to those most recently reported in the literature. The low incidence of immediate and late sequelae at the donor site and the characteristics of the bone graft confirm the suitability of iliac crest bone graft, in particular for use in reconstructive maxillo-facial surgery.

[Craniofacial fractures]. / Le fratture cranio-facciali.

Results of early combined maxillo-facial and neurosurgical treatment of 53 craniofacial fractures are referred. The fracture location was in 31 cases central midfrontal, 10 lateral supraorbital and 12 combined central and lateral fractures. 35 fractures interested the floor and the posterior wall of frontal sinus, lacerating the underlying dura and cortical tissue. In 19 fractures orbital displacement was present. The key points in the management of these patients are: 1) Early (within 1 to 5 days) and one stage neurosurgical-maxillofacial procedure. Immediate intervention is indicated only in case of evolutive neurological lesions; 2) wide exposition of all the injuries through bicoronal incision and bone flap; 3) assessment of fractures pattern and amount of bone loss; 4) reconstruction of craniofacial frame with osteosynthesis and autologous bone grafts (35 cases iliac crest, 7 split calvarial graft); 5) interosseous wiring is used in sutured mosaic, small bone fragments and intraoperative temporary fixation; miniplates are used for rigid fixation of craniofacial pillars; 6) for optimal cosmetic result reconstruction of supraorbital ridge, nasoglabellar region and zygomatic arch is essential; 7) fractures involving the sinus floor, posterior wall and the nasofrontal duct result in direct communication between the nose and intracranial cavity with high risk of infection and mucocele formation. Cranialization of the sinus removing the posterior wall and all the mucosa is mandatory. The nasofrontal duct, the floor and sinus dead space are obliterated with autologous bone chips. Osteoneogenesis occurred in all the cases.
