RESUMEN

OBJECTIVE: The objective of this cross-sectional study was to compare the difference in the oral health status and oral hygiene of orthodontic treatment with aligners (AL) and with fixed appliances (FA) in patients affected by craniofacial anomalies (CFA). MATERIALS AND METHODS: The sample consisted of 100 Caucasian patients affected by various CFA from two different hospitals. Fifty patients treated with AL were matched for sex, age and CFA with a control sample of 50 patients treated with FA. Patients' periodontal conditions were evaluated in both samples. O'Leary Plaque Control Record, bleeding on probing (BOP) and DMT/dmft Index were evaluated in both samples. RESULTS: The FA group presented an O'Leary Plaque Control Record of 60% ± 30, while AL presented an O'Leary Plaque Control Record of 40% ± 29.7 (p-value = 0.02), BOP was 22.1% ± 14 in FA and 12% ± 0.13 in AL (p-value = 0.03). The DMFT/dmft was not statistically different (p-value = 0.13). p-value was set at <0.039. CONCLUSION: The study shows that the sample with FA presented a higher O'Leary Plaque Control Record and BOP compared to the AL sample. AL might, therefore, be an interesting alternative to FA in patients with CFA, who generally have a lower level of oral hygiene.

RESUMEN

BACKGROUND: Closure of wide alveolar clefts with large soft tissue gaps and reconstruction of the dentoalveolar defect are challenging for the surgeon. Some authors successfully used interdental segmental distraction, which requires an additional surgical procedure. OBJECTIVE: This study evaluates the effectiveness of tooth borne devices utilized to orthopedically advance the lesser segments, with a complete approximation of the soft tissue of the alveolar stumps, allowing traditional simultaneous soft tissue closure and bone grafting, and avoiding the need for supplementary surgery. METHODS: Eight growing patients, 2 with unilateral complete cleft lip and palate (UCLP) and 6 with bilateral complete cleft lip and palate (BCLP), with large soft tissue and bony alveolar defects prior to bone grafting were prospectively selected. A banded rapid palatal expander (RPE) in BCLP and a modified RPE in UCLP combined with protraction face mask in younger patients or a modified Alt-Ramec in patients older than 12 years were applied. Radiographic and photographic records were available at T0, at the end of protraction (T1) and at least 1 year after bone grafting (T2). RESULTS: Patients with large gaps showed a significant reduction in the bony cleft area and approximation of the soft tissues at T1. All patients received bone grafting with good healing and ossification at T2. CONCLUSION: In growing patients with UCLP and BCLP with large gaps, presurgical orthodontic protraction seems to be an efficient method to reduce the cleft defect, minimizing the risk of post grafting fistulas, reducing the need for supplementary surgical procedures.

RESUMEN

OBJECTIVE(S): The aim of this study was to evaluate the long-term effectiveness of costochondral graft in hemifacial microsomia (HFM) type III patients. SETTINGS AND SAMPLE POPULATION: A sample of 10 patients affected by HFM type III treated during growth in the same Centre with costochondral graft (CCG patients group) is compared with a control group (CG) sample of 10 non-treated patients affected by the same malformation in order to understand whether surgery during growth provides advantages in terms of bony and facial symmetry after an 8-year follow-up. MATERIALS AND METHODS: The growth of the CCG was assessed on panoramic X-rays. To assess facial symmetry, a photometric evaluation on the frontal view was carried out. RESULTS: In CCG patients group the graft grown in mean less than the healthy ramus, a good facial symmetry was achieved after surgery, but was lost in the majority of the cases at the most recent control. In CG, occlusal canting slightly increased and facial asymmetry was relatively stable during the years. CONCLUSION: In patients with a congenital deformity, restoring the height of the ramus leads to an immediate restitution of facial symmetry, but in the long term, there is a return to the asymmetrical pattern. In CG, the asymmetry is stable during years with no increase of the facial deformity.

RESUMEN

INTRODUCTION: The objective of this prospective study was to compare the difference in pain perception between treatment with aligners (AL) and fixed appliances (FA) in patients affected by cleft and craniofacial anomalies (CFA). METHODS: The sample consisted of 100 syndromic caucasian patients affected by various CFA from 2 different hospitals. Fifty patients treated with AL were matched for sex, age, and CFA with a control sample of 50 patients treated with FA. A modification of the Mc Gill Pain Questionnaire was adapted to our needs. RESULTS: Statistical differences were found. Aligners induced more tightness and tension than FA, while FA induced more pain descriptors and patients reported a higher intake of painkillers. CONCLUSIONS: The results of this study documented a higher pain perception with FA than with AL in patients affected by CFA. The higher sensitivity to pain in cleft and craniofacial patients with fixed treatment could be related to their higher prior sensitization, given the past surgeries and orthodontic treatments. Thus, this study might suggest that Invisalign treatment might be a further interesting treatment option for patients with cleft in order to reduce their burden of orthodontic pain.

RESUMEN

OBJECTIVE: The objective of this retrospective longitudinal study was to evaluate short- and long-term results of the application of the Liou Alt-RAMEC (alternate rapid maxillary expansion and constriction) technique, a late orthopedic maxillary protraction technique, with intraoral anchorage, in patients with cleft. MATERIALS AND METHODS: Twenty-six patients with unilateral cleft lip and palate (UCLP) were consecutively treated with the Alt-RAMEC technique. The average age of the patients was 11.7 years (10.3-13.2 years) before protraction and 18.3 years (17.4-21.1 years) at long-term follow-up. A sample of nontreated patients with UCLP was used as a control group. It was matched for sex, skeletal class III, and age (11.3 years). The control sample had records at the end of growth (18.7 years). RESULTS: The sagittal advancement of A-point, after the application of the technique, was 5.7 (2.17) mm. Some mandibular dentoalveolar and positional adaptation was noted. The position of the maxilla was stable in the long term. On the other hand, the UCLP control group showed hardly any growth at the maxillary level during the long-term follow-up period. CONCLUSION: Our results showed that the Alt-RAMEC technique, performed at the correct time, with a double-hinged expander, followed by class III spring or elastic traction, 24 hours per day, allows for satisfactory maxillary protraction, with, at this stage, apparently stable long-term results. Nevertheless, as only 50% of the patients had long-term follow-up data, we are still unable to predict the percentage of patients which will not eventually need orthognathic surgery.

RESUMEN

The aim of this paper was to assess growth, speech, and aesthetic results at the completion of growth in patients with unilateral cleft lip and palate treated with the 2 stages Milan surgical protocol.Craniofacial growth was evaluated with cephalometric analysis and a theoretical need for orthognathic surgery.Nasolabial appearance was qualitatively assessed using the Asher McDade Aesthetic Index.Speech was assessed using the Gos.Sp.Ass '98 modified for Italian language scoring system.Burden of care was recorded in terms of number of secondary surgical procedures. All of the patients were treated and evaluated at San Paolo Hospital, Smile House, Milan.Fifty-two consecutive patients treated by the same surgeon were recalled, 12 patients did not come for assessment.The first surgical step (average age of 6 months) was cheilorhinoplasty (Millard modified Delaire technique) and soft palate rapair (Pigott). The second step (average age of 35 months) was hard palate and alveolar repair performed simultaneously with an early secondary gengivo alveolo plasty. Fifty-six percent of the patients did not need further surgery after the 2-stage surgery protocol.The 2-stage surgical protocol of Milano, Smile House, seems to be effective for treatment of unilateral cleft lip and palate, with good results in terms of speech, labial appearance, and alveolar cleft management. Nevertheless, maxillary growth was moderately impaired by the protocol.

RESUMEN

OBJECTIVE: Nasal stigma in patients with bilateral cleft lip and palate (BCLP) are a short columella and a flattened nasal tip. DESIGN: The aim of this study was to evaluate the aesthetics of adolescents with BCLP, operated with a modified Cutting primary columella lengthening technique, associated to a modified Grayson orthopedic nasoalveolar molding (NAM). SETTING AND PATIENTS: 72 BCLP patients were operated with this approach. Standardized photographic records were taken every 2 years. A group of 23 patients between 12 and 13 years of age was compared through normalized photogrammetry to a matched control of 23 noncleft adolescents. RESULTS: Nasal protrusion and length of the columella were very close to normal. On the other hand, nasolabial angle and interalar width were still excessively wide compared to the noncleft sample. CONCLUSIONS: NAM and primary columella lengthening in BCLP has allowed to avoid traditional secondary columella lengthening at 5 to 6 years of age and given the patients a more pleasing, near-normal nasolabial appearance until adolescence. Some of the patients will require correction of the nasal width at a later stage.

RESUMEN

The myomucosal buccinator flap, first described by Bozola in 1989, has become an important tool for intraoral defects reconstruction. In the literature, there is a variety of proposed myomucosal cheek flaps, both pedicled and island, based on the buccal or the facial arteries. From January 2007 to December 2011, the authors used a pedicled buccinator flap based posteriorly on the buccal artery to reconstruct partial lingual defects following tumor resection in 27 patients. The buccal fat pad was translated to cover the donor site defect. After 3 to 4 weeks from the original surgery, a second procedure under local anesthesia was performed to detach the pedicle and remodel the flap. The morphological and functional outcomes of the procedures were evaluated by the surgeons and a speech and language therapist. All patients presented satisfactory results. The authors consider the use of the described technique as the gold standard in the reconstruction of partial tongue defects after tumor resection.

RESUMEN

OBJECTIVE: The goal of this study was to evaluate the craniofacial morphology at 5 and 10 years of age and at the completion of growth, the need for final orthognathic surgery, and the orthodontic burden in a sample of patients with unilateral cleft lip and palate consecutively treated by the same surgeon with the same two-step protocol. DESIGN: A sample of 62 adult patients with unilateral cleft lip and palate was retrospectively collected (mean age, 17.5 years). Lateral cephalograms at three time points were traced. The need for orthognathic surgery was assessed, subdividing the sample into an orthognathic surgery group and nonorthognathic surgery group. Time and modality of orthodontic treatment were recorded. RESULTS: Cephalometric values related to maxillary growth (SNA, SNAns) and maxillomandibular relation (ANB, NAPg) were significantly different between the two groups already at 5 and 10 years of age. All patients presenting an ANB smaller than 2° at 5 years needed a Le Fort I osteotomy. Mandibular protrusion (SNB, SNPg) was not different at 5 and 10 years, but was different at the completion of growth. Patients with the same initial maxillomandibular relation did not show better growth when subjected to earlier or longer orthodontic treatment. CONCLUSION: Patients needing final jaw surgery had a more severe skeletal discrepancy during early childhood. The ANB angle at 5 years allowed doctors to identify 45% of the need for orthognathic surgery. The final craniofacial pattern does not seem to change significantly with early or prolonged orthodontic treatment.

RESUMEN

PURPOSE: This article presents a review of the literature and proposes a protocol for managing acute and chronic midfacial cocaine-induced injuries. MATERIALS AND METHODS: This report describes a series of 4 patients affected by cocaine-induced midline destructive lesions. Three patients came to the authors' attention after 18 months of drug withdrawal and underwent surgical treatments to restore nasal and palatal morphology and function, and the fourth patient was referred because of acute cocaine-induced destructive lesions and was treated by aggressive debridement. An 18-month drug-free period is planned before beginning any reconstructive procedures in this latter patient. RESULTS: Long-term follow-up showed stable results without relapse of palatal fistulas and good esthetic nasal appearance in all 3 patients undergoing reconstruction. The fourth patient did not show any disease progression and will be monitored for drug withdrawal. CONCLUSION: Chronic cocaine consumption may cause multiple types of damage to the soft and hard tissues of the midface. Acute lesions must be addressed with aggressive debridement. As a result of chronic injury, the palate and nose are deformed in a very complex way and the vascularity of the remaining local tissues may be compromised or inadequate for flap harvesting. Palatal and nasal reconstructions are very delicate operations and should be addressed separately to maximize the predictability of the result.

RESUMEN

Background: Maxillary hypoplasia and mandibular asymmetry may be corrected with orthognathic surgery after growth completion. For most stable results, some cases may require segmental Le Fort I osteotomies. Unfortunately, Invisalign's software (6.0 version) still has some inherent limitations in predicting outcomes for complex surgeries. This study explores the potential of aligners, particularly in multiple-piece maxillary osteotomies in both cleft and non-cleft patients. Method: Thirteen patients who underwent pre-surgical treatment with Invisalign were retrospectively matched in terms of diagnosis, surgical procedure, and orthodontic complexity with thirteen patients treated using fixed appliances. Virtual curves following the lower arch were employed to guide the correct pre-surgical positions of the upper teeth with a simple superimposition technique. The amount of impressions required in both groups to achieve satisfactory pre-surgical alignment of the segmented arches was compared. Results: one or no refinement phases were needed in the Invisalign group to reach an acceptable pre-surgical occlusion, while the amount of pre-surgical impressions needed to reach adequate coordination with fixed appliance treatment was slightly higher (p > 0.05). Conclusions: it appears that clear aligner could serve as an effective treatment for individuals necessitating segmental Le Fort I osteotomies when aided by the suggested simple superimposition approach.

RESUMEN

PURPOSE: To compare: (i) the incidence of soft tissue dehiscences; (ii) bone resorption before and after implant placement; and (iii) the survival and success rates of implants placed in two groups of patients with severe bone defects of the jaws reconstructed with autogenous onlay bone grafts alone (control group) or in association with autogenous pericranium coverage (study group). MATERIAL AND METHODS: Forty-four patients affected by severe atrophy of the alveolar ridges underwent bone reconstruction with vertical/tridimensional autogenous onlay grafts harvested from the calvarium or the mandibular ramus. In 23 patients (study group), grafts were covered with autogenous pericranium before suturing, while in 21 patients (control group) no coverage of the grafts before suturing was performed. After a 4-7 month waiting period, 199 implants were placed (105 in the study group, 94 in the control group) and 3-4 months afterward prosthetic rehabilitation was carried out. The mean follow-up after the start of prosthetic loading was 23.9 months (range: 12-48 months). RESULTS: The incidence of soft tissue dehiscences was 5,7% in the study group and 16% in the control group. The mean graft resorption before implant placement was 0.12 mm (SD ± 0.32) in the study group and 0.98 mm (SD ± 2.79) in the control group. The mean peri-implant bone resorption at the end of the follow-up period was 0.21 mm (SD ± 0.48) in the study group and 0.43 mm (SD ± 0.83) in the control group. The survival rate of implants was 99.1% in the study group and 100% in the control group, while success rate was 96.2% in the study group and 93.6% in the control group. CONCLUSIONS: The use of pericranium as an autogenous membrane for the coverage of onlay bone grafts seems to reduce the risk of soft tissue dehiscences after the reconstruction of atrophic edentulous ridges to reduce peri-implant bone resorption over time, while it seems to have no significant effect in reducing bone resorption in the reconstructed areas before implant placement.

RESUMEN

OBJECTIVES: Malocclusion affects the psychological wellness and social interaction, impacting negatively on adolescents' quality of life and self-esteem. Facial attractiveness is mostly based on the esthetics of the smile and patients seek orthodontic treatment mainly to improve aesthetics. The aim of this prospective clinical study is to compare the psychosocial impact of aligners (AL) and fixed appliances (FA) as orthodontic treatments in patients affected by craniofacial anomalies (CFA). METHODS: 100 syndromic Caucasian patients with CFA followed in two different hospitals were divided in two groups: 50 patients treated with AL and 50 patients treated with FA. The two groups were matched for gender, age and CFA and filled out a modified psychosocial impact of dental aesthetics questionnaire (mPIDAQ). RESULTS: Patients affected by CFA treated with AL reported a better psychosocial impact than patients treated with FA, showing higher esthetic self-perception and self-esteem, lower social interaction impairments, and lower physical/practical disturbances. CONCLUSIONS: The results of this study suggest that AL could be a valid alternative, especially in complex patients with CFA. Since AL application requires more cooperative patients the orthodontist should dedicate more time to motivate the patient to adhere to the treatment schedule.

RESUMEN

AIM: This study compares long-term mandibular growth between a group of Beckwith-Wiedemann Syndrome (BWS) patients who underwent glossectomy at an early age and a group of patients not operated. METHODS: Cephalometric measurements were performed in BWS patients comparing the data obtained between a group of patients operated at an early age and a group of non-operated patients who declined surgery. Statistics included independent sample T-test. RESULTS: Twenty-four out of 78 BWS patients followed since birth completed longitudinal cephalometric x-rays at age 5, 10 and 15. Eighteen patients needed early surgery. Eleven families accepted glossectomy at 2.3 ± 1.3 years of age; seven declined surgery. No differences in mandibular growth were found between the two groups. Inclination of maxillary incisors results were statistically greater in the non-operated group (operated compared to the non-operated group: 103.58 ± 11.30 Vs 108.98 ± 12.47; p-value 0.0168 at 5; 107.06 ± 7.98 Vs 115.14 ± 7.05; p-value 0.0206 at 10; 109.80 ± 4.68 Vs 116.75 ± 5.28; p-value 0.0233 at 15). CONCLUSION: Macroglossia has no role in the post-natal mandibular overgrowth in BWS and mandibular overgrowth is part of the syndrome. Therefore, early glossectomy does not change mandibular growth and does not prevent the development of class III skeletal malocclusion in these patients.

RESUMEN

PURPOSE: Injuries of the inferior alveolar nerve (IAN) related to endodontic treatment are being increasingly reported. However, consensus on the preferred intervention and the timing of and indications for surgical treatment is lacking. Here, we describe our experience with painful IAN injuries arising from endodontic treatment and requiring prompt microsurgical treatment. METHODS: Seven consecutive patients with painful IAN injuries were referred to the Maxillofacial Surgery Unit of San Paolo Hospital in Milan. All patients had undergone root canals endodontic treatment in the mandibular molar or premolar between 2007 and 2014. The time elapsed between injury and referral for surgical treatment ranged from 10 days to 20 months. Each patient was treated by one of several different microsurgical procedures, described herein. RESULTS: Overall, neurosensory status and IAN-related pain improved in all seven patients. The best results were obtained by IAN replacement with a sural nerve graft. However, complete sensory recovery was not achieved in any of the patients. CONCLUSIONS: Although our sample includes only seven patients, early surgical treatment with an interpositional sural nerve graft seems to allow neurosensory recovery. Less satisfactory results are achieved in patients with IAN injuries of > 12 months duration.

RESUMEN

BACKGROUND: The goal of this study was to evaluate with a three-dimensional method the long-term quality of alveolar ossification in unilateral cleft lip and palate patients who underwent early secondary gingivoalveoloplasty according to the Milan surgical protocol. METHODS: The sample consisted of 63 computed tomographic scans of unilateral cleft lip and palate patients in permanent dentition. The average age at the time of assessment was 15.7 years. Alveolar thickness, nasoalveolar height, nasal floor ossification, and hard palate morphology were evaluated using dental, axial, and coronal cuts on computed tomographic scans and three-dimensional models. All measurements were normalized and ratios of the affected side versus the nonaffected side were provided. Volume measurements and ratios of each hemimaxilla were added. The presence or absence of the permanent lateral incisor on the cleft side was also recorded. RESULTS: Alveolar thickness and height were ideal or good, respectively, in 89.5 and 91.4 percent of the sample. Insufficient ossification (<25 percent) was found in three patients (5.2 percent), and only one of them (1.7 percent) presented no bone bridging. A statistically significant association was detected between the degree of alveolar ossification, the type of nasal floor ossification, and volume ratio. CONCLUSIONS: Early secondary gingivoalveoloplasty seemed to allow an adequate ossification of both the alveolar and nasal region. Three-dimensional evaluation of the alveolar cleft ossification provided further information on alveolar bridging and allowed evaluation of the bone availability for implant placement. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

OBJECT: Surgical treatment of parotid malignancies may frequently involve facial nerve amputation to achieve oncological radical resection. The entire facial nerve branching from its exit from the stylomastoid foramen to the periphery of the gland is often sacrificed. The first reconstructive strategy is the immediate reconstruction of the facial nerve by directly anastomosing the trunk of the facial nerve to its distal branches by interpositional nerve grafting. The present study was performed to determine the adequacy of thoracodorsal nerve grafting for immediate repair of the facial nerve. The anatomical features of the thoracodorsal nerve make it particularly appropriate to match its trunk to the stump of the facial nerve at its exit from the stylomastoid foramen. Up to seven branches of the thoracodorsal nerve may be distally anastomosed to the severed distal branches of the facial nerve. More complex reconstruction may be addressed simultaneously by contemporary harvesting a de-epithelialized free flap from the same site based on thoracodorsal vessel perforators and preparing a rib graft from the same donor site. METHODS: Between October 2003 and August 2010, seven patients affected by parotid tumors (6 with parotid malignancies and 1 with multiple recurrences of pleomorphic adenoma) underwent radical parotidectomy with intentional sacrifice of the facial nerve to obtain oncological radical resection. In all patients, the facial nerve was reconstructed with an interpositional thoracodorsal nerve graft. In four patients, a de-epithelialized free flap based on the latissimus dorsi was transposed to cover soft tissue defects. Moreover, two of these patients also required a rib graft to reconstruct both the condyle and ramus of the mandible. With the exception of one patient affected by recurrent pleomorphic adenoma, all patients underwent radiotherapy after surgical treatment. RESULTS: All patients in our study recovered mimetic facial function. Facial muscles showed clinical signs of recovery within 5-14 (mean: 7.8) months, with varying degrees of mimetic restoration, and almost complete facial symmetry at rest in all patients. The House-Brackmann final score was I in two patients, II in two patients, and III in three patients. CONCLUSIONS: A thoracodorsal nerve graft to replace extratemporal facial nerve branching is a valid alternative technique to multiple classical nerve grafts, with good matching at both the proximal and distal anastomoses.

RESUMEN

Maxillectomies often result in anatomical defects that need to be reconstructed. In partial maxillectomies, the most significant defect is the formation of an oronasal or oral-antral fistula. This creates discomfort and needs to be addressed secondarily with local or regional flaps. Here, we describe a technique adopted in 8 patients in which limited maxillectomies are carried out in a way that preserves the nasal and sinus mucosa, preventing the formation of fistulas and allowing the use of flaps that would normally carry a high risk of fistula formation. Contemporary bone reconstruction with grafts was used in 2 patients. Sparing the sinus and nasal mucosa during maxillectomies is an easy, safe procedure that can prevent a number of complications and can be recommended in selected cases.

RESUMEN

UNLABELLED: Multidisciplinary approach to follicular thyroid carcinoma with giant mandibular and multiple sites metastases. Case report Metastatic tumors generally have poor prognosis, with short survival period and rarely indication to surgical treatment. In case of thyroid-differentiated cancer with distant metastases, prognosis is usually better, because of the possibility of treating metastasis by Radio Ablation by 131Iodine, after surgery. We report the case of a 65 years old woman, presenting with a giant mandibular metastasis from follicular thyroid carcinoma, originating from a cervico-mediastinal nonfunctioning goiter, with lung metastases. After the diagnostic work-up, she underwent left hemi-mandibulectomy, reconstruction by the placement of a precustomized titanium plate with condylar prosthesis and total thyroidectomy. Subsequently the Patient was treated by Radio Ablation by 131 Iodine, in four consecutive sessions. She is alive with no progression of the neoplasm after forty-six months follow-up. Even in advanced differentiated thyroid carcinoma, surgery should be taken into consideration, to treat the patient by complementary therapies and to improve the prognosis in term of survival. KEY WORDS: Advanced differentiated thyroid carcinoma, Metastatic differentiated thyroid carcinoma.
