Periocular Mohs micrographic surgery in Western Australia 2009–2012: A single centre retrospective review and proposal for practice benchmarks

Abstract

This study identifies potential benchmarks for Mohs surgeons when reviewing or establishing a periocular Mohs surgery practice and for doctors referring periocular tumours for surgical removal. These include the proportion of periocular cases managed jointly and the location, size of defect and number of stages involved in tumors repaired by Mohs surgeon alone compared to those repaired by oculoplastic surgeons.

Recurrence of periocular basal cell carcinoma and squamous cell carcinoma after Mohs micrographic surgery: a retrospective cohort study

“…Although the recurrence rate was relatively low in our study, the risk reported in some other studies was even lower (0·7–2·0%) . However, it is rather difficult to compare the recurrence rate found in this study with others.…”

“…This current study has a relatively long follow‐up time, which is available for all eligible patients due to data linkage. In prior studies the follow‐up is often less clearly defined, incomplete due to loss of study patients or rather short (median varying from < 12 to 30 months) . Although most BCCs recur within 3 years after treatment, sufficient follow‐up time is important because about one‐third of recurrences (in our study 27%) occur after that time, with 18% even occurring after 5 years …”

“…Furthermore, compared with other periocular MMS studies, this cohort contains a relatively high proportion of high‐risk KCs . They were often located at the medial canthus (44%, vs. 24–36% in the literature), were previously incompletely excised or recurrent tumours (25%) and, in cases of BCC, were of aggressive histological subtypes (44%).…”

Differences of Mohs micrographic surgery in basal cell carcinoma versus squamous cell carcinoma

“…There are many studies that analyze MMS considering different factors, such as patient age, anatomic location, histologic type of tumor, delay in treatment implementation, and gender . However, there are few studies comparing BCC MMS and SCC MMS .…”

“…BCC is the tumor most frequently treated with MMS, and SCC is the second most common type of tumor treated with this technique. 1,2 There are many studies that analyze MMS considering different factors, such as patient age, 3 anatomic location, [4][5][6][7] histologic type of tumor, [8][9][10] delay in treatment implementation, 11 and gender. 12 However, there are few studies comparing BCC MMS and SCC MMS.…”
