A case of dentigerous cyst removed by endoscopic modified medial maxillectomy （EMMM） technique

Background: Odontogenic maxillary cysts and tumours originate from the tooth root and have traditionally been treated through an intraoral approach. Here, we report the efficacy and utility of endoscopic modified medial maxillectomy (EMMM) for the treatment of odontogenic maxillary cysts and a tumour. Methodology: We undertook EMMM under general anaesthesia in six patients: four had radicular cysts, one had a dentigerous cyst, and one had a keratocystic odontogenic tumour. Results: The cysts and tumours were completely excised and the inferior turbinate and nasolacrimal duct were preserved in all patients. There were no peri- or postoperative complications, and no incidences of recurrence. Conclusion: Endoscopic modified medial maxillectomy appears to be an effective and safe technique for treating odontogenic cysts and tumours.

Modified Medial Maxillectomy

Background Endoscopic sinus surgery is an effective treatment option for patients with chronic rhinosinusitis (CRS), although approximately 20% of patients fail to improve with standard surgical procedures. Expanded procedures such as the endoscopic modified medial maxillectomy (EMMM) have been described in management of refractory maxillary sinusitis. Objective This study aims to review the current literature on the safety and efficacy of the EMMM for treatment of refractory maxillary sinusitis. Methods A literature search was performed of PubMed, Ovid, and Cochrane databases according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. English-language articles evaluating the EMMM procedure on patients with recalcitrant maxillary sinusitis were included. Full-text articles were obtained and evaluated by 2 reviewers independently, with a third reviewer for mediation of disagreements. Results Six studies met eligibility criteria and were included into the study, with follow-up ranging from 12 to 82.8 months. Two studies contained Level 2 evidence and 4 studies contained Level 4 evidence. EMMM was found to be effective in CRS and cystic fibrosis-related CRS (0% and 9.1% revision rate, respectively). Symptom resolution was noted 60% to 80% of patients. Four studies reported complications, with a total of 4 complications out of 211 patients. Conclusions There are no high-quality Level 1 studies evaluating the efficacy and safety of the EMMM procedure. Level 2 to Level 4 studies indicate that this procedure is relatively safe with a low complication rate and symptom resolution in up to 80% of patients with recalcitrant maxillary sinusitis.

Medial Maxillectomy

Background: Dentigerous cyst is one of the most frequent types of odontogenic cyst that usually involving an impacted, supernumerary or ectopically erupted tooth. One of the non-dental sites for ectopiceruption is the maxillary sinus. The traditional approach under such circumstances is a Caldwell-Luc maxillotomy, but this type of procedure may result in significant long-term complications. Endoscopic transnasal medial maxillectomy (ETMM) has several advantages, such as good il lumination, as wellas clear and magnified visualization. The new modified endoscopic transnasal medial maxillectomy(METMM) can provide good visualization and more functional result by preserving the nasolacrimalduct and the inferior turbinate. Purpose: We present this case to introduce the METMM technique forextirpation of any tumor in the maxillary sinus. Case: One case of dentigerous cyst with an ectopicleft maxillary 3 molar tooth in a 27 year old woman who presented with sinusitis. Management:Surgery with a METMM technique to enucleate the cyst, combined with functional endoscopic sinussurgery (FESS) for the sinusitis. The patient then evaluated subjectively for epiphora and objectivelywith nasoendoscopic examination. Conclusion: In this case, METMM was effective in accessing themaxillary sinus allowing for tumor extirpation, while preserving the function of the inferior tubinate andnasolacrimal duct. Keywords : Dentigerous cyst, maxillary ectopic tooth eruption, transnasal medial maxillectomy ABSTRAKLatar belakang: Kista dentigerous merupakan salah satu jenis kista otontogenik yang paling sering ditemukan, biasanya berhubungan dengan gigi impaksi, supernumeri atau gigi yang tumbuhektopik. Salah satu tempat erupsi ektopik adalah sinus maksilaris. Pendekatan tradisional dalamkeadaan ini adalah operasi Caldwell-Luc, tetapi teknik operasi ini dapat mengakibatkan komplikasijangka panjang. Maksilektomi medial transnasal dengan endoskopi (MMTE) memiliki beberapakeunggulan, seperti visualisasi yang jelas dan diperbesar. Teknik maksilektomi medial transnasaldengan endoskopi yang dimodifikasi (MMTEM) dapat memberikan visualisasi yang baik dan hasillebih fungsional dengan mempertahankan duktus nasolakrimal dan konka inferior. Tujuan: makalahini diajukan untuk memperkenalkan teknik MMTEM untuk ekstrirpasi massa yang berada di dalamsinus maksila, karena teknik ini memberikan hasil yang lebih fungsional. Kasus: melaporkan satu kasuskista dentigerous dengan gigi molar 3 yang erupsi ektopik pada sinus maksila kiri pada wanita 27tahun. Penatalaksanaan: kasus ini ditatalaksana dengan teknik MMTEM untuk mengenukleasi kistadan BSEF untuk sinusitis. Pasien kemudian dievaluasi secara subjektif dengan anamnesis mengenaiadanya epifora dan objektif dengan pemeriksaan nasoendoskopi. Kesimpulan: MMTEM terbukti efektifuntuk ekstirpasi tumor yang berada di dalam sinus maksila, dan teknik ini juga memberikan hasil yanglebih fungsional dengan dipertahankannya konka inferior dan duktus nasolakrimal.

According to International Society for the Study of Vascular Anomalies classification 2018, “hemangioma” should be classified as either vascular tumor or vascular malformation (VM). So-called “cavernous hemangioma” is categorized as VM. VM rarely involves the mucous membranes of the sinonasal cavity and typically arises unilaterally from the sinonasal cavity. Bilateral VM of the maxillary sinus is extremely rare. To the best of our knowledge, there is no previous report of bilateral VM of the maxillary sinus. Here, we describe the surgical treatment of bilateral cavernous hemangiomas of the maxillary sinus. These tumors were successfully resected by endoscopic modified medial maxillectomy (EMMM) after embolization. Endoscopic sinus surgery, particularly EMMM, produces access to the bilateral maxillary sinus and can prevent several complications.
