Coronoid hyperplasia: A review

Goh YC, Tan CC, Lim D

J Stomatol Oral Maxillofac Surg, 2020 Sep;121(4):397-403.
PMID: 31904534 DOI: 10.1016/j.jormas.2019.12.019

Coronoid hyperplasia is one of the rare causes of progressive limitation of mouth opening due to impingement of the enlarged coronoid process of the mandible on the zygomatic bone. A review was performed on all cases reports and case series on coronoid hyperplasia. Gender, age at treatment, age of onset, types of hyperplasia (unilateral/bilateral), associated history, treatment, surgical approach, preoperative mouth opening, intraoperative mouth opening, mouth opening at follow up and follow up period were recorded and analyzed. A total of 82 articles which reported 115 cases were included. Coronoid hyperplasia was commonly reported at mean age of 22.64 years old with male preponderance. Most of the cases were diagnosed and treated between the age of 11-20 years old. This condition commonly involved bilateral coronoid process of mandible. The mean width of preoperative mouth opening was 16.5mm and was improved to a mean mouth opening of 36.3mm intraoperatively. Mean mouth opening was 34.8mm at an average follow up of 19 months. While the etiopathogenesis of coronoid hyperplasia is still not conclusive, treatment with either coronoidectomy or coronoidotomy produced good improvement in mouth opening.

Mandibulotomy: an analysis of its morbidities

Nabil S, Nazimi AJ, Nordin R, Hariri F, Mohamad Yunus MR, Zulkiflee AB

Int J Oral Maxillofac Surg, 2018 Dec;47(12):1511-1518.

The mandibulotomy is a procedure that was developed to improve access in tumour resection. This study aimed to investigate the complications associated with mandibulotomy and analyze factors that could affect the risks of developing these complications. The hospital records of all patients who underwent a mandibulotomy as part of their tumour ablative surgery at two major centres in Malaysia were reviewed retrospectively. Demographic, clinical, and complications data were recorded and analyzed. Early postoperative complications occurred in 46.5% of the patients and post-radiation therapy complications in 16.1%. Wound dehiscence (27.9%) and inferior alveolar nerve injury (25.6%) were the common early postoperative complications. Dental injuries (9.7%) and plate exposure/infection (9.7%) were the common post-radiation therapy complications. Furthermore, inferior alveolar nerve injury and early abscess formation were significantly associated with the site of the mandibulotomy. The T-stage of a tumour but not the site of mandibulotomy was significantly associated with tumour margin clearance. Mandibulotomy does pose an added risk of complications for a patient undergoing tumour surgery. The benefits of mandibulotomy in terms of gaining margin clearance could not be proven in this study. The site of mandibulotomy appears to increase the risk of developing an inferior alveolar nerve injury.

Fulltext Effects of mandibular setback with or without maxillary advancement osteotomies on pharyngeal airways: An overview of systematic reviews

Tan SK, Leung WK, Tang ATH, Zwahlen RA

PLoS One, 2017;12(10):e0185951.
PMID: 29016682 DOI: 10.1371/journal.pone.0185951

BACKGROUND: Mandibular setback osteotomies potentially lead to narrowing of the pharyngeal airways, subsequently resulting in post-surgical obstructive sleep apnea (OSA).
OBJECTIVE: To summarize current evidence from systematic reviews that has evaluated pharyngeal airway changes after mandibular setback with or without concomitant upper jaw osteotomies.
METHODOLOGY: PubMed, EMBASE, Web of Science, and Cochrane Library databases were searched with no restriction of language or date. Systematic reviews studying changes in pharyngeal airway dimensions and respiratory parameters after mandibular setback with or without concomitant upper jaw osteotomies have been identified, screened for eligibility, included and analyzed in this study.
RESULTS: Six systematic reviews have been included. While isolated mandibular setback osteotomies result in reduced oropharyngeal airway dimensions, the reduction is lesser in cases with concomitant upper jaw osteotomies. Only scarce evidence exists currently to what happens to naso- and hypo-pharyngeal airways. There is no evidence for post-surgical OSA, even though some studies reported reduced respiratory parameters after single-jaw mandibular setback with or without concomitant upper jaw osteotomies.
CONCLUSION: Although mandibular setback osteotomies reduce pharyngeal airway dimensions, evidence confirming post-surgical OSA was not found. Nevertheless, potential post-surgical OSA should be taken into serious consideration during the treatment planning of particular orthognathic cases. As moderate evidence exists that double-jaw surgeries lead to less compromised post-surgical pharyngeal airways, they should be considered as the method of choice especially in cases with severe dentoskeletal Class III deformity.

Fulltext Desmoid fibromatosis of submandibular region

Ali R, Parthiban N, O'Dwyer T

J Surg Tech Case Rep, 2014 Jan;6(1):21-5.
PMID: 25013548 DOI: 10.4103/2006-8808.135144

Desmoid fibromatosis is a benign yet locally aggressive tumor with a tendency to recur. It causes considerable morbidity particularly when it arises in a small area in the head and neck region. This tumor is extremely rare in the submandibular region. We report a case of desmoid tumor in the submandibular region in a 32-year-old male who presented with right submandibular swelling postextraction of right lower wisdom tooth. Excision biopsy was carried out initially following inconclusive fine needle aspiration and discussion at multidisciplinary meeting. The tumor recurred 4 months following initial excisional biopsy necessitating a more radical secondary approach involving segmental mandibulectomy. Intraoperatively we also noted that the tumor was originating from the site of previous wisdom tooth extraction, raising the question of surgical trauma as precursor of desmoid tumor. We achieved a negative resection margin and a complete remission for 24 months.

Fulltext A 20-year experience of immediate mandibular reconstruction using free fibula osteocutaneous flaps following ameloblastoma resection: Radical resection, outcomes, and recurrence

Chai KS, Omar FH, Mat Saad AZ, Wan Sulaiman WA, Halim AS

Arch Plast Surg, 2019 Sep;46(5):426-432.
PMID: 31550747 DOI: 10.5999/aps.2018.01487

BACKGROUND: The mandible is an important structure that is located in the lower third of the face. Large mandibular defects after tumor resection cause loss of its function. This study assessed the outcomes and tumor recurrence after immediate mandibular reconstruction using a free fibula osteocutaneous flap following radical resection of ameloblastoma.
METHODS: This is a retrospective non-randomized study of outcomes and tumor recurrence of all patients diagnosed with mandibular ameloblastoma from August 1997 until August 2017 (20 years) requiring free fibula osteocutaneous flap reconstruction at a single institution. The patients were identified through an electronic operative database; subsequently, their medical records and photo documentation were retrieved.
RESULTS: Twenty-seven patients were included in this study. Eighteen patients were male, while nine were female. The majority of the patients (48.1%) were in their third decade of life when they were diagnosed with ameloblastoma. All of them underwent radical resection of the tumor with a surgical margin of 2 cm (hemimandibulectomy in cases with a large tumor) and immediate mandibular reconstruction with a free fibula osteocutaneous flap. Two patients required revision of a vascular anastomosis due to venous thrombosis postoperatively, while one patient developed a flap recipient site infection. The flap success rate was 100%. There was no tumor recurrence during a mean follow-up period of 5.6 years.
CONCLUSIONS: Mandibular ameloblastoma should be treated with segmental mandibulectomy (with a surgical margin of 2 cm) to reduce the risk of recurrence. Subsequent mandibular and adjacent soft tissue defects should be reconstructed immediately with a free fibula osteocutaneous flap.

Squamous cell carcinoma is the most common malignant neoplasm of the upper aerodigestive
tract, and presentation is usually at the late stages when the diagnosis is made. Recurrence
after 1st therapy is common especially in the locoregional area of the tumour. For cancers
affecting the oral cavity, oropharynx, and mandible, “COMMANDO” (Combined
Mandibulectomy and Neck Dissection Operation) is one of the surgical approaches which
constitutes of primary tumour resection, mandibulectomy and neck dissection. We describe a
case of rapid locoregional recurrence following 1st surgical procedure of bilateral tonsillectomy
and extended neck dissection of oropharyngeal squamous cell carcinoma in a young healthy
individual without history of alcohol and tobacco abuse involving the right buccal region which
after positron emission tomography was done, showed involvement of right pterygoid muscles,
right-sided tongue muscle, and right mandible. The patient underwent redo salvage surgery
and reconstruction with anterolateral thigh flap.
