Prosthetic rehabilitation of resected orbit in a case of mucormycosis

A Case Series of Prosthetic Rehabilitation of Post-COVID Rhinorbitocerebral Mucormycosis Ocular Defects: A Digital and Analog Experience

Removal of a part of or the entire orbit results in facial defect, causing psychological trauma to the patient, apart from anatomic loss. This case series presents 6 clinical cases of prosthetic rehabilitation of ocular defects related to post-COVID-19 ROCM by both analog and digital workflow. The basic objective of this case series was to achieve a well retained, user-friendly, maxillofacial ocular prosthesis with esthetic accuracy. Unique size and shape of the ocular defect in each case, variety of skin tones, age range of patients and compromised neuromuscular control made each of the six cases challenging. This clinical series apart from proposing a digital & analog algorithm for rehabilitating ocular defects also illustrates analog workflow for 4 cases and digital workflow for 2 cases for fabrication of ocular prosthesis.

Positioning of iris in an ocular prosthesis: A systematic review

AIM

To evaluate different methods, techniques, and concepts documented in the literature to assess iris positioning accurately to the related dimensions needed to effectuate maxillofacial rehabilitation of ocular prosthesis.

SETTINGS AND DESIGN

This systematic review was conducted as per the PRISMA guidelines which is the most opted reporting protocol.

MATERIALS AND METHODS

Two electronic databases PubMed and Cochrane Library) were searched for manuscripts published from 1969 till September 30, 2019. An electronic search (of peer review restricted to English language dental literature was conducted to identify the relevant scientific article on iris positioning in maxillofacial prostheses. Two observers independently read the abstracts and selected 17 full text articles fulfilling the inclusion criteria.

STATISTICAL ANALYSIS USED

No meta-analysis was conducted due to heterogeneity of data obtained.

RESULTS

All the 17 documented articles related to determination of the iris positioning to perform maxillofacial prosthetic rehabilitation depicting the use of a strip of plastic template, a Boley's gauge, a millimeter ruler, a pupillometer, window light, an ocular locator with fixed caliper, inverted anatomic tracings, a transparent graph grid were reviewed systematically.

CONCLUSION

Currently, there is no evidence in the form of a systematic review of the available literature discussing the best technique available for perfectly matching the iris positioning. However, the latest techniques making use of digital technology such as digital photography, is believed to be more precise for iris positioning in the ocular prosthesis.
