Canaliculitis is an uncommon condition presenting with epiphora, medial eyelid swelling, pouting punctum, and punctal discharge. Surgical treatment with canaliculotomy with incision of the punctum is the treatment of choice when medical management fails. The risk of epiphora and functioning of the healed canaliculus is unknown. We describe a modification to the standard technique by leaving the punctum intact, incising the canaliculus along its full extent, and intubating the upper system with a silicone monocanalicular stent.
The lower punctum is dilated, and a Bowman probe inserted into the canaliculus. A no. 11 Bard-Parker blade is used to incise the canaliculus along its full extent, beginning 2 mm medial to the punctum, leaving the punctum intact. The contents of the canaliculus are curetted, and purulent material, drained. The wound is left open, and a mini-Monoka silicone monocanalicular stent (FCI Ophthalmics, Marshfield Hills, MA) is inserted to bridge the gap between the intact punctum and lacrimal sac. The incision is left to heal by secondary intention.
This modified punctum-sparing canaliculotomy was performed on 3 patients. In one patient, the upper and lower canaliculi were treated. The other 2 patients had involvement of the lower canaliculus only. All 3 patients tolerated the procedure well with full resolution of symptoms. No complaints of postoperative epiphora were made, and the system was patent to irrigation postoperatively.
Punctum-sparing canaliculotomy with monocanalicular intubation is an effective treatment for canaliculitis and may be particularly useful in cases in which both upper and lower canaliculi are involved and the risk of postoperative epiphora and canalicular scarring is unknown.
泪小管炎是一种不常见的疾病,表现为溢泪、内眦眼睑肿胀、突出的泪小点和泪小点分泌物。当药物治疗失败时,采用泪小管切开术联合泪小点切开术是治疗的首选方法。术后溢泪和修复后的泪小管功能的风险尚不清楚。我们描述了一种改良的标准技术,即保留泪小点完整,沿整个泪小管切开,并使用硅胶单腔泪道管对上部系统进行插管。
扩张下泪小点,将 Bowman 探针插入泪小管。使用 11 号 Bard-Parker 刀片沿整个泪小管切开,从泪小点内侧 2 毫米处开始,保留泪小点完整。刮除泪小管内容物,排出脓性物质。伤口保持开放,插入 mini-Monoka 硅胶单腔泪道管(FCI Ophthalmics,马什菲尔德山,MA)以桥接完整泪小点和泪囊之间的间隙。切口让其二期愈合。
3 例患者接受了改良的保留泪小点的泪小管切开术。其中 1 例同时治疗了上下泪小管,另外 2 例仅累及下泪小管。所有 3 例患者均能很好地耐受该手术,症状完全缓解。术后无溢泪抱怨,术后系统对冲洗通畅。
保留泪小点的泪小管切开术联合单腔插管是治疗泪小管炎的有效方法,对于上下泪小管均受累且术后溢泪和泪小管瘢痕形成风险未知的病例可能特别有用。
