Myofibrosarcoma is a distinct mesenchymal malignancy which commonly occurs in head and neck region. It has a high tendency for local recurrence and distant metastasis. 39-year-old male presented with epistaxis, nasal obstruction and left sided complete loss of vision. He underwent functional endoscopic sinus surgery and guided biopsy. MRI scan showed a lesion epicentred in the left maxillary sinus, superiorly extending into the orbit. He underwent Class 4b maxillectomy with neck dissection, tracheostomy and free flap reconstruction. Histopathological examination yielded final diagnosis as myofibrosarcoma of maxilla. The patient was planned for adjuvant radiotherapy and has been disease free for 3 years.

Aramany\'s classification of postsurgical maxillectomy defects was introduced for partially edentulous situations, and has been widely used for education and effective communication among practitioners. Numerous classifications of maxillofacial defects, based on surgical procedure, resultant defects, or prosthodontist\'s perspective after rehabilitation, exist in the literature. However, no single classification has incorporated all these factors. The purpose of this review was to highlight the classification systems and describe a pragmatic classification series for edentulous maxillary arch defects (maxillectomy) by applying the Aramany classification criteria, to enhance treatment outcomes and communication among practitioners.
An electronic search of the literature published in English was conducted using the PubMed/MEDLINE and Google Scholar database. Keywords used were \"maxillectomy classification\" AND \"surgical resection,\" \"maxillectomy classification\" AND \"complete edentulous.\" In addition, a manual search was also performed followed the same criteria in the following journals: Journal of Prosthetic Dentistry and Journal of Prosthodontics.
Several classification systems for partial dentition were found in terms of size, location, dentition, and extension of the defect (isolated or communication defects). The findings revealed a variety of maxillectomy defect classifications for partially dentate, considering surgical factors and rehabilitation. However, no study or classification system exist for the edentulous arch defects.
Different classification systems for maxillectomy defects exist in the literature, only for partially dentate patients. To the authors best knowledge, no classification system for completely edentulous maxillary arch defects have been proposed till date. A simple classification system with clear characteristics for edentulous maxillectomy dental arch defects has been proposed. This classification was modeled after Aramany classification for easier memorization and application.

Temporalis muscle flap is a versatile flap which can be used for reconstruction after major head and neck resections, owing to its optimal bulk, constant and reliable vascularity, ease of access to recipient site, minimal donor site morbidity and relatively better cosmetic outcome compared to more bulky flaps like pectoralis major myocutaneous flap or deltopectoral flap. The flap can be used as a muscle flap, myofascial flap (muscle with temporalis fascia). We present our series of 12 cases of temporalis muscle flap reconstruction for various head and neck reconstructions. The aim of this study was to analyse the application of temporalis muscle flap in head and neck reconstructions and its outcome.

Ameloblastic carcinoma (AC) is an extremely rare malignant odontogenic tumor. The mean age of occurrence for all 141 AC cases analyzed in our systematic review study was 43.59±19.51 years. Males were more affected than females, and the mandible was predominantly affected compared with the maxilla. The main clinical manifestation was a painful or painless swelling with ulceration and radiographic features usually displayed as mixed cystic or solid changes. Surgical resection was the first recommended method of management. Fourteen cases had cervical lymph node spread, 19 had distant metastasis (most commonly in the lung), and 33 had recurrence. We present a rare case of AC involving the maxillary region. Locally extensive surgical resection was carried out. Ablative defects after maxillectomy resulted in the communication of oral cavity and nasal cavity/maxillary antrum and would bring about difficulties in mastication, deglutition, and speech. A submental island flap was applied to close the oronasal and oroantral fistula. The flap and the wounds healed well, with excellent outcomes in terms of appearance, the function of speech, and swallowing on follow up. The submental island flap provides a relatively thin, easy-to-harvest, and well-vascularized tissue, which makes it a reliable option in soft tissue reconstruction of the oral and maxillofacial region.

OBJECTIVE: This literature review reports the current evidence for the use of zygomatic implants in head and neck oncology patients for the prosthetic rehabilitation of defects of the mid-face and maxilla.
METHODS: MEDLINE, Embase and Cochrane databases were searched using strict search terms. Two independent reviewers reviewed the articles and applied inclusion and exclusion criteria.
RESULTS: Literature search revealed 437 articles, and following application of the inclusion criteria, 32 articles were included for analysis. Overall survival rates of 77%-100% were reported with few complications, although only four centres presented data on 20 or more patients. Primary implant placement at time of resective surgery has been shown to be an effective means of accelerating rehabilitation along with early loading protocols. The role of radiotherapy in implant failure has not been fully elucidated, and it is clear that zygomatic implants can be successfully used in the irradiated patient. Providing support for maxillary obturators was the most common use reported with both splinted and unsplinted implants.
CONCLUSIONS: Zygomatic implants provide remote anchorage for a variety of oral and facial prostheses that contribute to the improved function and quality of life for patients being treated for maxillary and mid-facial tumours.

Maxillary defects can be resolved by prosthetic obturation, autologous tissue reconstruction, or a combination of both. However, there is still controversy in the selection of the optimal approach. Therefore, the aim of this study was to systematically review evidences comparing the performance of obturators and flaps in patients after maxillary oncological ablation. Both electronic and manual searching approaches were conducted to identify eligible evidence. Two reviewers independently assessed the risk of bias. In addition, the same reviewers independently extracted the data. Meta-analyses were performed using Revman 5.3, and best evidence synthesis was performed. Sixteen studies were included and a total of 528 participants were analyzed. All studies were assessed at low quality. Results of this meta-analysis showed weak evidence in the difference between obturators and flaps on the outcome regarding word intelligibility (P = 0.004) and masticatory efficiency (P = 0.002). However, no differences were detected regarding speech intelligibility and nasalance. All studies were compiled into the best evidence synthesis. The sum of 31 evidences was considered. Twelve evidences were evaluated at a moderate level, such as speech, mastication, pain, salivation, taste sensations, and mouth opening. Except the outcomes of word intelligibility, masticatory efficiency, and mouth pain, other moderate evidences showed no difference between obturators and flaps. In conclusion, both obturators and flaps might be effective in patients\' rehabilitation functions after maxillary ablation. However, some advantages were observed when using surgical reconstruction over prosthetic rehabilitation. Additional high-quality studies are needed to provide more solid evidence before applying these results into clinical practice.

OBJECTIVE: Different lesions affecting the midfacial regions require surgical reconstruction. The aim of this study was to assess the different methods used in midfacial reconstruction after maxillectomy procedures. The various reported surgical reconstructive techniques focusing on the esthetic and functional outcomes are to be reviewed in this article.
METHODS: A thorough PUBMED and hand-search of journals of relevance was performed on related terms and yielded 772 titles of which 45 abstracts were selected and obtained as full articles for further evaluation while the rest were excluded by title/abstract. According to the inclusion criteria; 14 of these studies were used to complete this article.
RESULTS: In this review we showed that fibular and radial vascularized grafts were the most commonly reported methods in literature with a few other options. Computer aided design and surgical planning has been also reviewed and seems to be a rapidly evolving option for maxillofacial reconstruction. Lack of RCTs (randomized controlled trials) and large scale case series was noticed in this review making the evidence of poor quality.
CONCLUSIONS: Methods of evaluation of reconstruction options mainly qualitative and subjective made the evaluation of the techniques in this review difficult.

The aim of this study was to review patients with tumours extending to the posterior portion of the upper gingiva and hard palate, and to evaluate the postoperative outcomes. Ten consecutive patients with tumours in the upper gingiva and hard palate, who underwent maxillectomy with internal dissection of the masticator space by the transmandibular approach, were reviewed retrospectively. Among the 10 patients, the pathological diagnosis was squamous cell carcinoma in seven, adenoid cystic carcinoma in one, malignant melanoma in one, and osteosarcoma in one. Loco-regional control was achieved in eight of nine patients (88.9%). Three patients had residual moderate trismus. Cosmetic issues were not noted in any patient. En bloc resection of the maxilla with the internal portion of the masticator space and neck through the parapharyngeal space by the transmandibular approach is a useful and satisfactory technique for the excision of a tumour with involvement of the posterior portion of the upper gingiva and hard palate.
