Ectopic teeth have been rarely described in non-dental and non-oral localizations. Ectopic tooth eruption in maxillary sinus usually runs across incidentally during routine radiological or clinical evaluation because it is generally asymptomatic. If it occurs symptomaticaly; the findings like purulent rhinorrhoea, facial pain, headache, swelling, epistaxis and epiphora can be seen. It is often ...

Caldwell-Luc procedure, canine impaction, dentigerous cyst, ectopic tooth. Abstract A case of a large dentigerous cyst associated with canine tooth in the maxillary antrum is presented. This case is of interest because of its extensiveness and the presence of an ectopic tooth in the roof of the maxillary sinus. Theoretical aspects of canine impaction and cyst formation are reviewed. The managem...

Dental implants can be accidentally introduced into the maxillary sinus both during and after surgical installation. Both situations are uncommon and usually induce sinusitis or others important complications.1 The aim of the present study was to report a rare clinical case of late displacement of a dental implant into the maxillary sinus, in which a Caldwell-Luc (CL) approach was performed, fo...

An unusual case of an impacted right maxillary third molar that was accidentally displaced into the maxillary sinus during exodontia and was surgically retrieved almost 2 years later is described. The tooth was removed under general anesthesia, after maxillary sinus exposure through Caldwell-Luc approach. Postoperative recovery was uneventful. Six months after the retrieval surgery, the maxilla...

A case of an ameloblastic carcinoma in an unusual situation in the maxilla is presented. The lesion is characterized histologically by areas with features of a typical ameloblastoma and areas with anaplastic transformation. A Caldwell-Luc operation was followed by a recurrence after 3 years. Due to the advanced age and poor general health of the patient an enlarged, but not radical operation wa...

Ectopic eruption of teeth in non-dental sites is a rare phenomenon; It may be symptomless but is more commonly associated with inflammatory symptoms. It can present in a variety of ways such as chronic or recurrent sinusitis, sepsis, nasolacrimal duct obstruction, headaches, ostiomeatal complex disease and facial numbness. The treatment of choice is surgical excision which is mostly carried out...

Implant placement in the posterior maxilla often requires elevation of the sinus floor, which can be achieved through either the modified Caldwell-Luc or the crestal osteotome technique. The objectives of this study were to evaluate (a) the resistance to perforation of maxillary sinus membranes obtained from formaldehyde-fixed cadavers in vitro, (b) the frequency and extent of membrane perforat...

Introduction. Large maxillary cysts occasionally expand into the maxilla and erode the maxillary sinus and nasal cavity. The Caldwell-Luc procedure is the recommended treatment for large maxillary sinus cysts. However, it is hard to preserve the nasal space in the case of large maxillary sinus cysts that penetrate into the nasal cavity. Methods. A 22-year-old man who had large maxillary sinus c...

Since 1992, 42 patients at the University of Pennsylvania have been treated for inverted papilloma (IP). Thirty-three patients were managed endoscopically with or without a Caldwell Luc approach (CLA) and retrospectively analyzed. The CLA, which involves a gingivobuccal incision for access to the maxillary sinus, is distinguished from a formal Caldwell Luc procedure. These 33 patients with hist...

PURPOSE Paranasal sinus mucocele is a benign, expansile mass which can occur as a result of trauma or spontaneous obstruction of a sinus tract. The purpose of this study was to describe and compare the clinical characteristics of primary mucoceles occurring in patients with no previous sinus surgery history or known cause of mucoceles and secondary mucoceles resulting as a complication followin...
