A large-scale study of treatment methods for foreign bodies in the maxillary sinus

Abstract

Recently, reports regarding a foreign body in the maxillary sinus have considerably increased, with the majority being iatrogenic cases resulting from dental treatment. This study involves an extensive review of the Japanese literature, including 112 papers from 1978 to 2017. These papers documented total 407 cases of a foreign body in the maxillary sinus. Among the 392 cases for which treatment details were available, the Caldwell-Luc approach was used for 216, the alveolar approach for 116, extraction using nasal endoscopy for 15, and extraction using oral endoscopy for eight. Spontaneous passage occurred in 19 cases, follow-up with medication was used in 17, and "other" was noted in one. This study determined that surgical removal remains the most common method for treating both tooth roots and other foreign bodies and that the Caldwell-Luc approach is used in majority of the surgeries. No marked differences were noted among the removal methods used in relation to the foreign body type.

Clinical and radiological characteristics of oro‐antral communications/fistulae due to implant dentistry procedures: A cross‐sectional retrospective study

“…However, the Caldwell‐Luc approach was used as well for foreign body removal and OAF closure. A recent review 29 supports the present findings revealing foreign bodies were removed using the Caldwell‐Luc approach. Likewise, there were no large differences in the removal methods employed, which supports lack of postoperative outcome differences between the IDE and OE groups.…”

“…In the present study, implant dentistry was the etiology of OAF/OAC and secondary sinusitis in 27% of the cases. Statistical examinations conducted between 1978 and 2017 revealed a marked increase over time in implant dentistry related cases 29 …”

“…Nowadays, the demand of implant dentistry treatments is increasing, especially by patients with atrophic partially or fully edentulism in the subantral regions, requiring sinus augmentation 29 . Reports associating sinus augmentation with OAF and maxillary sinusitis are not rare anymore 30 …”

Modified Caldwell-Luc Technique to retrieval of tooth fragment displaced into the maxillary sinus: A case report

“…Although small fragments may remain asymptomatic, removal is recommended, as even after long asymptomatic periods, complications such as oroantral fistulaes, mucoceles, cellulitis or, more commonly, maxillary sinusitis, which can affect 48% to 73% of patients, may arise (Hara et al, 2018;Manor et al, 2018;Gnigou et al, 2019).…”

“…Treatment choices are influenced by the presence and degree of sinus inflammation, size, location and positioning of the dental fragment, which is best evaluated by computed tomography (Huang et al, 2011;Hara et al, 2018). The literature describes the alveolar approach and the Caldwell-Luc (CL) surgery as being the two main techniques for retrieving dental roots from the maxillary sinus, however a retrieval attempt through the extraction socket can enlarge the oroantral communication, potentially causing an oroantral fistulae, and is related to low success rate (Huang et al, 2011).…”
