Combined approach by middle and inferior antrostomy for endosinusal inclavated tooth root

In the recent years, the development of stomatology with emphasis on dental implants procedures has led to an increase in the number of sinonasal complications. Sinonasal complications of dental disease and treatment are an important cause of sinus pathology, being responsible for 10-12% of all causes of chronic maxillary rhinosinusitis.

The main etiological factors involved in odontogenic sinusitis are represented by dental fillings, tooth roots in traumatic extraction, dental implants displacement and parts of broken instruments. The diagnostic work-up includes evaluation of the symptoms, history of dental treatment, dental examination, CT scan and nasal endoscopy.

The treatment is surgical and can be represented by transnasal endoscopic technique performed by the otorhinolaryngologist or a transoral technique performed by the maxillofacial surgeon when oro-antral fistulas are present. The endoscopic approach is preferred but has its limits when the tooth root is placed in the alveolar recess, or at the level of the anterior, medial and lateral wall of the maxillary sinus. Concurrent middle and inferior antrostomy provides a better view of the sinus and increases effectiveness of the surgical treatment with minimal physiological damage.
