“…4 These teeth usually displace through the periosteum into the infratemporal fossa just adjacent to the lateral pterygoid plate and inferior to the lateral pterygoid muscle. 6 If excessive force is applied during the attempt to retrieve the tooth that lies in between the periosteum and the posterolateral wall of the maxilla, the tooth may further be displaced upward into the skull base carrying greater risks for morbidity. 4 The access for the surgical removal of the tooth from the infratemporal fossa is not only difficult to obtain but also has the potential for morbidity because it hosts vital anatomic structures.…”

“…1 Because the exact localization of the displaced tooth is difficult to determine clinically, different radiographic techniques facilitate the surgical procedure. 6 To determine the localization of the displaced teeth, occlusal, panoramic, occipitomental, and lateral radiographs can be useful. 4 Although panoramic radiography is helpful in preoperative controls, it may sometimes disorient the diagnosis in the case of the tooth's displacement into the infratemporal fossa because of the superimposition of the anatomic structures located at the site of the infratemporal fossa.…”

The removal of an impacted maxillary third molar is an easy procedure for an oral and maxillofacial surgeon. The most commonly seen complications associated with this type of surgery are excessive hemorrhage, infection, pain, swelling, trismus, and root fractures. Although rarely encountered, unexpected complications may also arise during this procedure, such as the displacement of the tooth into an anatomic space. In this article, a case of a maxillary left third molar accidentally displaced into the infratemporal fossa is presented, and the delayed removal of the tooth after 3 weeks from the initial unsuccessful attempt is described, along with the correlating reasons. The role of the radiologic analysis in determining the localization of the tooth, including the routine panoramic radiographs and more importantly the volumetric computed tomographic scans, is stated. The different surgical treatment options are classified, and the potential for morbidity in the surgical removal of the tooth from the infratemporal fossa is presented by ranging the vital anatomic structures running through it.

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. Keywords: Dentigerous cyst, Maxillary sinus, Modification of Caldwell Luc approach 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.

“…Maxillary third molars uncommonly displaced through the periosteum into the infratemporal fossa just adjacent to the lateral pterygoid plate and inferior to the lateral pterygoid muscle [7]. Excessive force application and incorrect use of elevator during the attempt to retrieve the tooth may further displace the tooth upward into the skull base carrying greater risks for morbidity [6, 7].…”

The removal of impacted maxillary third molars is one of the most common procedures performed in oral and maxillofacial surgery units with low rates of complications and morbidity. A few cases of accidental displacement of third molars into adjacent anatomical spaces, such as the infratemporal fossa, the pterygomandibular space, the maxillary sinus, buccal space, or the lateral pharyngeal space, during surgical interventions have been reported. In this paper, a case of a maxillary third molar accidentally displaced into the pterygopalatine fossa is presented, and the removal of the tooth via intraoral approach is described.
