Odontogenic sinusitis is diagnosed when sinonasal disease is thought to be of dental origin. Odontogenic sinusitis accounts for approximately 10% of sinusitis cases and is most common among 40–60 years old with a slight female predominance.

The causes and pathogenic mechanisms underlying odontogenic sinusitis (OS) include direct bacterial infections of the maxillary sinus mucosa arising from apical or marginal periodontitis [1–3]. Extraction of the causative tooth is reasonable because, in the long term, treatment of the causative tooth is essential to eliminate the source of infection. However, there has been no consensus regarding the preservation or extraction of the causative tooth [4,5], and several dental treatments for OS, including tooth extraction, root canal treatment (RCT), and apicoectomy, have been reported [6]. This prospective study aimed to statistically analyse the cure rates of OS and the contributing factors of cure after a stand-alone treatment with a tooth extraction in patients diagnosed with OS and indicated for causative tooth extraction.

Acute rhinosinusitis (ARS) is either a continuum of a viral upper respiratory infection or bacterial infection [1]. Because the maxillary teeth are located close to the maxillary sinus, ARS may also arise from an odontogenic source (odontogenic sinusitis, OS). Odontogenic infections are a known cause of sinusitis, but often overlooked [2]. OS may follow periapical or periodontal dental infection, pericoronitis or dental implant infection. Iatrogenic factors, such as foreign bodies in the sinus and a non-closing oroantral communication following a tooth extraction, can also result in OS [3]. Odontogenic infection can spread further from the maxillary sinus into the other paranasal sinuses and then opacification of the ethmoids is often present [4].

An oroantral fistula (OAF) is the chronic pathologic result of oroantral communication (OAC), characterised by epithelialisation between the oral cavity and the maxillary sinus [1,2]. OAF incidence varies, according to different studies, from 0.3 to 5% and increases after the age of 30 years [2]. The most frequent causes of OAF are procedures performed on the upper teeth, in particular, complicated teeth extractions [2,3]. Other causes include odontogenic sinusitis, maxillary dental cysts, tumours, radiotherapy sequela, and trauma [1–4]. Because OAFs are closely related with sinusitis, the cases are encountered in otorhinolaryngology departments.
