Injections of local anaesthetic to the palate are well known to be poorly tolerated. The absolute requirement of a palatal injection for the removal of maxillary third molars has never been investigated. The aim of this study was to document the current practice of palatal anaesthesia for extraction of these teeth with local anaesthesia as practised by oral and maxillofacial surgeons.
A postal survey was sent via the ANZAOMS office to all oral and maxillofacial surgeons who were members of the Australian and New Zealand Association, a total of 131. A response rate of 64 per cent (n = 84) was achieved. The frequency of administration and the factors that determined the decision to administer a palatal injection were assessed, as well as the methods employed for reducing the injection discomfort.
The majority (77 of the 84) "always" gave a palatal injection for the removal of maxillary third molars, four respondents administered an injection "most of the time", and two respondents "occasionally". Significantly, one respondent "never" gave a palatal injection. The majority (76 per cent) utilized at least one adjunct in order to reduce the discomfort of the injection.
The results of this survey suggest that for removal of maxillary third molars the requirement of the poorly tolerated palatal injection may not be absolute as conventionally taught and demonstrates the need for further investigation.
众所周知，对上腭进行局部麻醉注射的耐受性较差。上颌第三磨牙拔除术中对上腭注射的绝对必要性从未得到研究。本研究的目的是记录口腔颌面外科医生在使用局部麻醉拔除这些牙齿时进行腭部麻醉的当前做法。
通过澳大利亚和新西兰口腔颌面外科医生协会办公室向该协会的所有131名口腔颌面外科医生发送了邮政调查问卷。回复率为64%（n = 84）。评估了注射的频率、决定进行腭部注射的因素，以及用于减轻注射不适的方法。
大多数人（84人中的77人）“总是”在上颌第三磨牙拔除时进行腭部注射，4名受访者“大多数时候”进行注射，2名受访者“偶尔”进行注射。值得注意的是，有1名受访者“从不”进行腭部注射。大多数人（76%）使用了至少一种辅助手段来减轻注射的不适。
本次调查结果表明，在上颌第三磨牙拔除术中，耐受性较差的腭部注射的必要性可能不像传统教导的那样绝对，这表明有必要进行进一步研究。
