J Clin Med 2024; 13:3613. [PMID: 38930140 PMCID: PMC11204853 DOI: 10.3390/jcm13123613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 05/27/2024] [Accepted: 06/18/2024] [Indexed: 06/28/2024] Open
Abstract
Background: Defects of the ascending ramus of the mandible, including the condylar head and neck or the whole temporomandibular joint (TMJ), are difficult to reconstruct. Reconstruction is mainly based on the use of alloplastic joint prosthesis, costochondral grafting, distraction osteogenesis of the dorsal part of the mandibular ramus, or osseous microvascular flaps of various origin. With the objective of developing a method that overcomes the restrictions of these methods, we recently introduced a sequential chimeric flap consisting of a lateral femoral condyle flap (LFC) and deep circumflex iliac artery flap (DCIA) for reconstruction of up to half of the mandible and the condylar head and neck. Methods: The chimeric flap was used in four patients with the following diagnoses: therapy-refractory osteomyelitis, extended recurrent odontogenic keratozyst, Goldenhar syndrome, and adenocarcinoma of the parotid gland. After a diagnostic workup, LFC and DCIA flaps were harvested in all patients and used in a sequential chimeric design for the reconstruction of the mandibular body and condylar head and neck. Results: Follow-up from at least 24 months up to 70 month after surgery showed a successful reconstruction in all four patients. The LFC provided a cartilaginous joint surface, allowing for a satisfactory masticatory function with a stable occlusion and unrestricted mouth opening and preserved or regained lateral and medial excursions in all patients. The DCIA allowed for a bony reconstruction anatomically resembling a non-atrophied mandibular body. No flap-related complications were observed. Conclusions: The sequential chimeric LFC and DCIA flap is an appropriate method for reconstructing up to half of the mandible and the condylar head and neck. It is suitable in cases where alloplastic joint replacement cannot be used or where other methods have failed. Due to the necessity of harvesting two flaps, the burden of care is increased, and a careful indication is required. The technique is reserved for maxillofacial surgeons who have already gained significant experience in the field of microsurgery.

Abstract
The treatment of temporomandibular joint (TMJ) ankylosis in children is a great challenge for surgeons. Costochondral graft (CCG) is a common method of reconstructing the TMJ in children. However, the growth pattern of CCG is unpredictable. In this study, we introduced a surgical-orthodontic approach and evaluated the growth results of the mandible and maxilla in children with TMJ ankylosis through 3-dimensional computed tomography measurements. A prospective cohort study was conducted on child patients diagnosed as having TMJ ankylosis between September 1, 2018 and June 1, 2020. Computer-aided virtual mandibular position guided the CCG, and removable functional appliance was used after surgery. The maximal incisal opening (MIO), the maxilla height, and the length of mandibular ramus were determined. Paired t test was performed to analyze the differences among various stages. Six patients (3 females, 3 males; aged 6-9 y) were included in this study. MIO was 12.4 mm before surgery and improved to 36.8 mm after 42.8 months' follow-up. Mandible length increased by 5.1 mm in the affected side and by 5.3 mm in the unaffected side, without significant difference. The affected maxilla height increased by 6.7 mm, which was more than 5.0 mm in the unaffected side. In conclusion, continued growth of mandible and maxilla can be achieved through CCG combined with functional appliance treatment for children TMJ ankylosis.

Characterization of Upper Airway and Analysis of Potential Risk Factor Associated with OSA in Patients with Unilateral Temporomandibular Ankylosis and Micrognathia Deformities. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2023:101708. [PMID: 38006945 DOI: 10.1016/j.jormas.2023.101708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 11/22/2023] [Accepted: 11/22/2023] [Indexed: 11/27/2023]
Abstract
OBJECTIVE To ascertain the airway characteristics in patients with unilateral temporomandibular joint ankylosis and maxilla-mandibular deformities (UTMAMD) and investigate the potential risk factors associated with obstructive sleep apnea (OSA) among UTMAMD patients. METHODS Authors conducted a retrospective single-center study to assess and compare study group consisting of a cohort of 32 patients diagnosed with UTMAMD between January 2011 and July 2022 with control group including 54 participants. The study group was further divided into two subgroups based on the presence or absence of OSA in patients. Parameters related to the upper airway were measured and analyzed using three-dimensional reconstruction of computed tomographic scans. The measurements of airway parameters were compared between study group and control group and between two subgroups. Pearson correlation analysis was used to identify the factors associated with the presence of OSA, and a multiple variable regression model was used to identify risk factors for OSA. RESULTS Airway volume (VOL), Minimum cross-section area (min CSA), mean CSA, tilt in sagittal plane (TS), and tilt in sagittal plane (TC) in velopharynx; VOL, airway length (AL), min CSA, mean CSA, TS, TC, and airway deviation (AD) in glossopharynx; min CSA, TS, and AD in hypopharynx were found difference with significance between study group and control group. Lateral dimension/anterior-posterior dimension (LAT/AP) ratio in velopharynx and min CSA, TC, and LAT/AP ratio in glossopharynx were significant different between patients with UTMAMD with OSA and without OSA. CONCLUSIONS The upper airway of patients with UTMAMD exhibits significant narrowing and distortion, rendering them susceptible to suffer from OSA. Patients with UTMAMD and OSA demonstrate more elliptical airways, and the glossopharyngeal LAT/AP ratio is a predictive indicator for the occurrence of OSA.

Wadde KR, Nadkarni S, Mathai P. Long term complications of costochondral graft reconstruction in temporomandibular joint ankylosis of the young- a systematic review. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2023; 124:101437. [PMID: 36914003 DOI: 10.1016/j.jormas.2023.101437] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 02/27/2023] [Accepted: 03/09/2023] [Indexed: 03/13/2023]
Abstract
Costochondral graft has been a popular reconstruction choice in the past for temporomandibular joint ankylosis in young individuals. However, accounts of growth hampering complications have also been observed. Our systematic review aims to compile all existing evidence to determine the occurrence of these unfavourable clinical outcomes as well as factors affecting them to provide a better judgement on further use of these grafts. A systematic review was conducted following PRISMA guidelines where databases like PubMed, Web of science and Google Scholar were searched for the purpose of data extraction. Observational studies performed on patients younger than 18 years of age with a minimum follow-up of one year were selected. Incidence of long term complications like reankylosis, abnormal graft growth, facial asymmetry and others were considered as outcome variables. Eight articles with a total of 95 patients were selected where complications like reankylosis (6.32%), graft overgrowth (13.70%), insufficient graft growth (22.11%), no graft growth (3.20%) and facial asymmetry (20%) were reported. Other complications like mandibular deviation (3.20%), retrognathia (1.05%) and prognathic mandible (3.20%) were also observed. Our review concludes that the occurrence of these complications was noteworthy. Thus use of costochondral graft for reconstruction in temporomandibular ankylosis in young patients holds significant risk in development of growth abnormalities. However, modifications in surgical procedure such as use of appropriate graft cartilage thickness and the presence and type of interpositional material can favourably affect the frequency and type of growth abnormality.

Abstract
Autogenous methods for reconstruction arthroplasty (RA) for the surgical management of the temporomandibular joint (TMJ) have been extensively reported. The present review was aimed to systematically review and pool data on clinical outcomes of autogenous grafts for RA in subjects with TMJ ankylosis. Major electronic databases and prominent subject-specific journals were searched up to December 2020. Randomised controlled trials (RCT), cohort studies, and retrospective studies reporting outcomes of autogenous grafts for RA in TMJ ankylosis were included. A total of 35 studies with 700 subjects was included. The most commonly employed grafts were costochondral grafts (CCG) and coronoid process grafts. Postoperative change in maximum incisor opening (MIO) was comparable amongst all grafts and was in the clinically acceptable range (27.21-31.38 mm). The recurrence rate was comparable for all grafts and was ≈ 8% except for coronoid grafts, where the recurrence rate was 2.98%. Growth assessment for CCG revealed that 55.89%, 30.89%, and 13.24% of subjects depicted optimal growth, overgrowth, and undergrowth, respectively. Within the limitations of the present review, the recurrence rate for all grafts was comparable except for coronoid graft, which depicted least recurrence rate and resultant postoperative change in MIO was in the clinically acceptable range.

Abstract
INTRODUCTION AND IMPORTANCE The computer-guided approach for the patient-specific TMJ replacement is considered an ultimate reliable option in advanced cases. However, dislocation of the condylar head could happen with the concave fossa design. A flat design was described and used in this case. CASE PRESENTATION A 15 years old male patient with mandibular asymmetry and class IV recurrent ankylosis of the right TMJ received a patient-specific artificial joint with computer-guided gap arthroplasty and orthognathic corrective mandibular surgery for the left side. The fossa component was made entirely flat, and the patient was followed up over the next year. CLINICAL DISCUSSION Customized TMJ prosthetic solutions are reliable in advanced cases, especially when facial corrections are indicated; however, the commonly used concave design showed reported dislocations requiring some design modifications as proposed in the presented case. CONCLUSION The flat fossa design of the artificial TMJ secures the same results as the anatomical fossa design without the incidence of dislocation.

Abstract
Reconstruction for large-scale temporomandibular joint (TMJ) defects can be challenging. We have used the medial femoral condyle (MFC) osseocartilaginous flap for repair of TMJ defects. The aim of this paper was to describe our technique and to present the preliminary results. The MFC osseocartilaginous flap was used as a free vascularized graft for TMJ defect in four patients who had undergone resection for benign tumor of the TMJ region (n = 2) or TMJ ankylosis (n=2). A computer-assisted technique was used in all cases. Symmetry of the mandible was objectively evaluated by postoperative computed tomography. Complications were recorded during follow-up visits. Lower extremity functional status was assessed by the Lower Extremity Functional Scale (LEFC) questionnaire. The MFC osseocartilaginous flap success rate was 100%; bony union was obtained in all four patients, and normal occlusion was achieved within 6-11 months after surgery. No flap-related complications occurred. All patients were satisfied with their postoperative facial symmetry and oral function. The LEFC score ranged from 72 to 80, indicating normal lower extremity function. Vascularized MFC osseocartilaginous flap appears to be a reliable option for reconstruction of large-scale TMJ defects.
