“…We did not get more information from radiographs, exact position of inferior dental nerve was confirmed only during surgery. CT, 3D CT, would have given more details, but cone beam CT [2,4] nowadays more commonly used to locate the position of an ectopic lower third molar with better resolution and less radiation exposure than conventional CT scans. In our case patient was not financially affordable so further investigations like CT or cone beam CT was not taken to locate the exact position of tooth and its relation to the inferior dental canal.…”

In this case the tooth was found inferio-lingual to the inferior dental nerve in the left angle of the mandible and found to be ectopic [2].Investigations commonly used for the impacted lower third molar are IOPA and OPG. In our case we used OPG and lateral oblique view of the mandible, impacted lower third molar was placed immediately adjacent to the inferior dental (I D) canal on the left angle and lower border of the mandible.…”

A 38-year-old male was referred to Maxillofacial Surgery Department by an Orthodontist with pain and swelling on the left side of the jaw along with the difficulty of opening the mouth. Pain was sharp, intermittent and radiating to the temple and to the back of the neck. He gave a history of similar episode previously twice and resolved with the antibiotic therapy. On examination swelling was present on the left side near the angle, which was diffused and extending to the neck region. The mouth opening was reduced to 22mm. The OPG [Table/ Fig-1] showed obliquely and deeply impacted left third molar (Class 3, Position C) immediately related to the inferior dental nerve and above the angle of the mandible. There was increase in the size of the follicular space associated with the crown of the tooth. Lateral oblique view [Table/ Fig-2] shows the mesioangularly impacted third molar which is Class III, positioned 1.5cm distal to the roots of the second molar and close to the left angle with bulky roots. All other teeth on left quadrant were healthy and case was diagnosed to be odontogenic infection from the mesioangular Class III, Position C impacted left lower third molar.As the patient was continuing with the symptoms, the decision was to remove the impacted ectopically placed mandibular left lower third molar tooth under general anaesthesia with antibiotic cover (Cefotaxim 1gm BD and inj Metronidazole 500mg TID through intravenous route for seven days). As the position was not favourable for trans-oral procedure, extra-oral approach was planned. Patient was taken for extra oral approach after explaining the benefits of procedure which will prevent the damage to the inferior alveolar nerve, possibility of mandibular angle fracture and difficulties arise due to the limited accessibility and visibility to perform the procedure intra orally. The written informed consent was taken prior to general anaesthesia. A standard submandibular approach was used with Risdon incision [Table/ Fig-3]. Platysma divided the marginal mandibular nerve branch of facial nerve identified and retracted. After dividing the masseter muscle, through the sub periosteal reflection the lateral surface of the ramus aBstRaCt Extra oral approach for removal of the lower third molar is uncommon. This case report illustrates an example of removal of lower third molar by extra-oral approach preserving the inferior dental nerve was exposed. The site of impacted tooth presented as smooth elevation, guttering was done using the bur taking the advantage of follicular space crown was exposed. The neurovascular bundle was placed just above the crown of the impacted tooth [Table/ Fig-4] carefully dissected out of the canal. The buccal surface of the crown exposed used as a guide for entire tooth removal. The follicle was removed and thoroughly copious irrigation done after smoothing the sharp margins with bur and bone file. Inferior dental nerve replaced in the bed again [Table/ Fig-5] and soft tissue closure done in layers. Postoperative recovery was good, ...

ABSTRAKKista adalah penyebab pembengkakan kronis yang paling sering pada rahang dibandingkan tulang lain karena banyaknya sisa epitel odontogenik. Kista yang dibentuk dari epitel odontogenik merupakan yang terbanyak di rahang. Kista dentigerous merupakan kantung jaringan ikat yang berisi cairan dengan berbatas epitel skuamos berlapis yang terbentuk di sekitar mahkota gigi yang tidak erupsi atau dentikel. Kista ini sering disebut kista folikular karena hasil pembesaran folikel yang berasal dari akumulasi cairan antara epitel tereduksi dengan email gigi. Shear dan Spreight mengatakan bahwa etiologi terjadinya kista dentigerous bisa karena gigi impaksi. Seorang pasien laki -laki berusia 41 tahun dilaporkan datang ke klinik Bedah Mulut RSUP Dr. Sardjito dengan keluhan utama benjolan di bawah telinga kiri, tidak terasa sakit ukuran 4x3x3 cm muncul kurang lebih 8 bulan sebelumnya. Awalnya kecil kemudian membesar, pasien telah menjalani perawatan dari puskesmas dan tidak ada kemajuan. Penatalaksanaan kasus ini adalah enukleasi kista di bawah anestesi umum. Evaluasi dilakukan 4 bulan post operasi dan tidak ada tanda kambuh. Riwayat penyakit sistemik dan alergi obat tidak ada. MKGK. Desember 2015; 1(2): 99-103Kata kunci: kista dentigerous, enuklasi ABSTRACT: Dentigerous Cyst Enucleation on Coronoid Mandibular Sinistra under General Anesthesia. Cyst is the most common caused of chronic swelling in the jaw compared to other bone as there are a lot of odontogenic epithelium. Cyst formed from odontogenic epithelium is the most encountered case found in dental practice. Dentigerous cyst is a sac formed of connective tissues filled with liquid and lined with stratified squamos epithelium border which was developed around un-erupted dental crown or denticle. This kind of cyst is also known follicular cyst on a reason that swelling follicle is derived from liquid accumulation between tooth enamel reductions with dental email. Shear and Spreight stated that impacted tooth is the ethiology of dentigerous cyst. We are reporting a case of41 year old man who came to Dr. Sardjito central hospital with chief complain of swelling under left ear, painless, 4x3x3 cm sized and increase within 8 months since its developed. The patient was treated in the Primary Health Care but no improvement reached. This case was managed with enucleated cyst under general anesthesia. No sign of recurrence after 3 months follow up and patient evaluation. No systemic disease and allergic symptom was found in this patient. MKGK. Desember 2015; 1(2): 99-103Keywords: dentigerous cyst, enucleation PENDAHULUAN Salah satu kelainan dalam mulut yang sering ditemukan dalam praktik bedah mulut adalah kista. Kista merupakan suatu rongga patologis yang berisi cairan atau semi cairan, tidak disebabkan oleh akumulasi pus. Kista bisa dibatasi oleh epitel, atau tidak dan dapat menyebabkan pembesaran intraoral dan ekstraoral yang secara klinis dapat menyerupai tumor jinak. 1 Kista adalah pembentukan rongga patologis di dalam subtansi organ dan merupakan suatu kantong yang ra...
