A 22-year-old man was referred to the Department of Oral and Maxillofacial Surgery with a chief complaint of heaviness on the left side of the face, mild headache and intermittent dull pain in the left side of the face and in front of the left ear.Intraoral examination revealed absence of left maxillary third molar. Panoramic radiograph revealed that the tooth was placed much higher in the sinus along the posterolateral wall [Table/ Fig-1]. On Computed Tomography (CT) imaging the tooth was found to be partially in the maxillary sinus and partially in the infratemporal fossa, communicating through the posterolateral wall of maxillary sinus, lateral to the lateral pterygoid plate [Table/ Fig-2].The patient was admitted for surgery under General Anesthesia (GA) after thorough physical examination and routine blood investigations. Prior to the surgery a duly signed written informed consent was obtained from the patient.The Caldwell Luc operation, originally described in the late 1800s, is an approach to the anterior wall of the maxillary sinus by making a window just below the canine fossa and the anterior wall is breached [1], but in the present case we had to modify this approach as the tooth was located posteriorly in the sinus, so a vestibular incision was given starting from tooth #23 till 1cm distally to tooth #27. A full thickness mucoperiosteal flap was reflected. The posterior part of the anterior wall of the maxillary sinus was breached by making a window by rosette round bur along with a 4mm chisel and bone rongeur, over teeth #26 and 27, the lateral wall was also resected till the posterolateral wall was approached [Table/ Fig-3]. The tooth was found in the posterolateral aspect of the maxillary sinus and infra-temporal fossa, guttering of the bone was done around the tooth, distal retractor was used and the tooth was retrieved along with the cystic lining with the help of a curette [Table /Fig-4]. Post-operative recovery was uneventful; the patient was prescribed analgesics and antibiotics. He was followed up for three months and found to have no complaints.

ABSTRACTDentigerous or follicular cysts of odontogenic origin are innocuous benign cysts that are often linked with the crowns of permanent teeth. A dentigerous cyst circumventing permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. In the maxilla or upper jaw region, the impacted teeth are often displaced and/or shift into the maxillary sinus and apart from the nasal septum, mandibular condyle, coronoid process and the palate, to harbour such ectopic eruptions of teeth. We report a rare case of an impacted left third molar of maxilla, associated with dentigerous cyst. The impacted tooth was embedded in the anterosuperior part of the infratemporal space. The cyst along with the tooth was removed using a modified Caldwell Luc incision.
Ossifying fibroma of bone is a central neoplasm of bone and it is more common in young adult with marked predilection for mandible and also it is more common in female. Lesion is generally asymptomatic until growth produces a noticeable swelling and mild deformity. It presents an extremely variable roentographic appearance depending upon the stage of development. This lesion is composed basically of many delicate interlacing collagen fibers, seldom arranged in discrete bundle, interspersed by large numbers of active, proliferating fibroblasts. The lesion should be excised conservatively. We present a case of huge ossifying fibroma arising from maxilla.
In today's stressful circumstances, people are migrating away from conventional cures and methods to check for deeper healing and solutions. People are switching to life and incorporating spirituality into their regular life to make them comfortable and happier. Trying to get some spiritual healing techniques that work, many people have chosen to support and promote this new approach. There is something for everyone.
