Evaluating tooth extraction as a stand-alone treatment for odontogenic sinusitis

Abstract

Background

There are multiple treatment methods for odontogenic sinusitis (OS); however, the optimal treatment remains unclear.

Aims/Objective

To determine the cure rate of OS after tooth extraction and the factors contributing to the cure.

Material and methods

We prospectively identified 37 patients diagnosed with OS with an indication for causative tooth extraction. Before and three months after tooth extraction, the patients were assessed using sinus computed tomography and classified as either cured or uncured based on the absence or presence of soft tissue shadow in the maxillary sinus. The prognostic factors were analysed by comparing the two groups.

Results

There were ten patients for whom all data could be obtained. The mean age of the patients at the time of tooth extraction was 53.8 ± 12.9 years (range, 34–75 years). In seven patients, the soft tissue shadow in the maxillary sinus disappeared; these patients were classified as cured. Uncured patients were significantly younger than cured patients (59.9 vs. 39.7 years).

Conclusions and significance

Tooth extraction effectively treated OS in 70% of patients. However, even after tooth extraction, OS may not improve, particularly in younger patients.

Chinese Abstract

背景：牙源性鼻窦炎（OS）有多种治疗方法； 然而, 最优治疗仍不清楚。

目的：确定拔牙后 OS 的治愈率及其治愈的影响因素。

材料和方法：我们前瞻性地确定了 37 名诊断为 OS 且具有拔牙适应症的患者。在拔牙前和拔牙后三个月使用鼻窦计算机断层扫描对患者进行评估, 并根据上颌窦内无或有软组织阴影分为已治愈或未治愈。 通过比较两组进行预后因素分析。

结果：获得了共10名患者的所有数据。 患者的平均年龄拔牙时为 53.8±12.9 岁（范围为34-75 岁）。 在七名患者中, 软上颌窦组织阴影消失； 这些患者被归类为治愈。 未治愈患者明显比治愈患者年轻（39.7岁相对于 59.9 岁）。

结论和意义：拔牙有效地治疗了 70% 的OS患者。 然而, 即使在拔牙后, OS 也可能不会改善, 尤其是年轻患者。
