口腔外科医による含嗽交通閉鎖術後の術後経過観察の実践

Oroantral communication (OAC) is an abnormal passage between the oral cavity and maxillary sinus, most commonly occurring after extraction of posterior maxillary teeth. Untreated defects can lead to chronic sinusitis or progress to an oroantral fistula, complicating oral rehabilitation. Although surgical closure techniques are well described, evidence on postoperative follow-up care is limited. This study assessed oral surgeons' follow-up practices after OAC closure and factors influencing confidence in postoperative management.

An anonymous online survey was distributed through professional associations and institutional networks. The questionnaire collected data on demographics, clinical practices, and self-reported confidence in postoperative follow-up management after OAC closure. Associations between experience, follow-up frequency, and confidence were analyzed using Kruskal-Wallis and Spearman's rank correlation tests.

Forty-eight oral surgeons participated. Most were male (95.8%) and aged 40-49 years (38.8%). First follow-up was usually scheduled within two weeks, and two visits were most common. More than half (55.1%) used self-developed protocols, while 24.5% followed established guidelines. Confidence in postoperative follow-up was generally high: 83.7% of respondents reported being very confident. Years in practice correlated positively with self-reported confidence in postoperative follow-up management (p < 0.001), while follow-up frequency showed no association.

Postoperative OAC follow-up practices show consistent early review timing but variation in protocol sources, and surgeon confidence is positively associated with years in practice. Because recruitment used a convenience sampling with potential selection bias, findings should be interpreted as descriptive benchmarking rather than generalizable estimates.
