Introduction:

The use of zygomatic implants is now a predictable and consolidated therapeutic alternative in the rehabilitation of patients with atrophic maxilla. However, like any surgical technique, it has a few complications that should not be ignored.

Objective:

The aim of this study is to analyse the frequency and causes of maxillary sinusitis caused by treatment with zygomatic implants.

Material and method:

A systematic review was performed using different databases, searching the prevalence and causes of maxillary sinusitis due to treatment with zygomatic implants.

Results:

Most studies cite sinusitis as one of the most common post-operative complications, finding 4.93 cases per 100 zygomatic implants placed.

Discussion:

The fact that sinusitis is related to the intra-sinusal technique has led to the development of techniques in order to avoid it, such as the extra-sinusal approach of implants or the use of combined surgical techniques such as simultaneous sinus lift with implant placement or coverage with buccal fat pad.

Conclusion:

Despite being the most common complication, the prevalence is quite low; a fact that confirms the success of treatment with zygomatic implants.
