Complete Mobilization of the Cheek Zone for Orbit Exenteration

A Systematic Review and Meta-Analysis of Ocular and Periocular Basal Cell Carcinoma with First-Time Description of Dermoscopic and Reflectance Confocal Microscopy Features of Caruncle Basal Cell Carcinoma

Background: Basal cell carcinoma (BCC) of the ocular and periocular region is characterized by a painless progressive extension. An early diagnosis can limit the extent of facial tissue involvement and subsequent resection resulting in better cosmetic and functional results. Objectives: The aim is to provide the largest and most up-to-date overview of ocular and periocular BCCs. We also reported the first case of caruncle BCC investigated by dermoscopy and reflectance confocal microscopy (RCM). Methods: A systematic review and meta-analysis (Prospero ID CRD583032) were carried out by searching PUBMED-MEDLINE, including all articles with a full-text English version and with BCCs in eyelids, medial and lateral canthus, caruncle, conjunctiva, and orbit. The following data were collected: authors, year, title and type of publication, medical specialization, number, sex, age and comorbidities of the patients, anatomic localization of the disease, clinical and dermoscopic aspect, histological examination, and treatment. Results: We identified 731 articles through a database search, of which 236 articles matched our inclusion criteria. A total of 71.730 patients with ocular and periocular BCCs were included in the present study, and all data collected were reported in a dataset. Most of the articles included were described by ophthalmologists (67.5%), dermatologists (11.2%), or plastic surgeons (5.6%). The proportional meta-analysis revealed varying significance and heterogeneity for each type of study included. Conclusions: BCC more frequently affects the lower eyelid. The most common BCC subtype of ocular and periocular area is the nodular form. Limited data are available concerning the application of dermoscopy and RCM in this area. RCM may be particularly useful for early diagnosis, mapping, and treatment monitoring of ocular and periocular BCCs. Surgery still remains the first-choice treatment.

The Role of Perforator Island Flaps for the Reconstruction of Mid-Facial and Periorbital Large and Deep Defects

PURPOSE

To describe a single-hospital experience with the reconstruction of broad and deep periorbital defects with perforator island flaps (PIFs).

METHODS

Twenty cases of reconstruction of complex defects in the periocular region using PIF were selected and revised. All cases were performed in the university hospital of the University of São Paulo, Ribeirão Preto, Brazil, from September 2018 to July 2024. Data collected included intraoperative and postoperative photographic documentation, lesions diagnoses, defect sizes and locations, PIF sizes and axes of mobilization, postoperative follow-up duration, and complications.

RESULTS

All patients underwent periorbital reconstruction with PIF after tumor resection. In 7 cases, the defects involved the lower lid cheek junction, and in 10 cases, they extended into the medial canthus, including 3 cases of orbital exenteration. The lateral periorbital region was affected in 2 patients. The mobilization of the flaps was from the lower cheek toward the lower eyelid in 7 patients, toward the medial canthal area in 10 patients, and horizontally to cover defects in the medial and temporal regions in 2 cases. The size of the resultant defect averaged 7.9 cm2. The mean follow-up time was 40 months. The flap remained viable in 100% of cases.

CONCLUSION

PIFs are a versatile option for reconstructing large periorbital defects and extended exenterations, and this technique should be included in the repertoire of procedures for managing mid-facial tumors.

Reconstruction of Orbital Exenteration Defect With Cheek or Combined Cheek and Forehead Advancement Flaps

PURPOSE

To review the outcomes of orbital exenteration defect reconstruction using cheek or combined cheek-forehead advancement flap.

METHODS

Charts of 14 patients who underwent reconstruction of the exenterated orbit with cheek advancement flap were reviewed. In surgery, a cheek flap elevated via a nasofacial sulcus incision, and preperiosteal dissection was advanced over the defect. The upper orbital defect, if necessary, was covered with a forehead flap, which was dissected through an incision in the midline or temporal forehead and advanced inferiorly.

RESULTS

In all patients (7 women, 7 men; mean age, 65 years), total (n = 7) or extended (n = 7) exenteration was performed for a malignant tumor. In 12 patients (86%), the defect was primarily closed with cheek flap alone (n = 6) or cheek plus forehead (n = 6) advancement flaps. Eight patients received radiotherapy before and after surgery. Four patients (29%) had a total of 6 postoperative complications (skin graft infection, orbital cavitary abscess, osteomyelitis, chronic skin ulcer, and 2 sino-orbital fistulae). The mean follow-up duration was 43 months (range, 11-79 months).

CONCLUSIONS

Cheek advancement flap can be used alone or together with a forehead advancement flap to cover the orbital defects after total or extended exenteration. This repair may be resistant to radiotherapy-related complications in some cases.

Reconstruction of Orbital Exenteration Defects with Cheek Rotation Flaps: Indications, Technique, Complications, Rehabilitation, and Survival

The objective of this study was to examine the role of cheek rotation flaps in the reconstruction of orbital defects after exenteration. From January 2000 to August 2018, patients undergoing orbital exenteration and reconstruction with cheek rotation flaps were enrolled in this retrospective study. All patients were evaluated for wound complications, orbital rehabilitation, tumor relapse, and survival. Thirty patients completed the study. Fourteen complications allocated to 11 patients were assessed. The most common complications were seroma (13%), temporary facial nerve weakness (13%), and partial necrosis of the flap (10%). A major complication occurred in a total of two patients (7%), so that surgical correction was necessary. Eleven patients had a relapse; 15 patients died as part of the follow-up. Fifteen patients were treated with facial prostheses. The overall survival rate was 61% after 1 year and 42% after 5 years. Follow-up periods ranged from 6 to 95 months. Cheek rotation flap reconstruction after exenteration is a reliable method with a low rate of major complications. It is indicated when an approach to the parotid gland or the neck region is necessary because of suspected lymph node metastasis and in elderly patients because of their skin's laxity. It can be performed as primary or secondary reconstruction. Good esthetic results can be achieved, especially after endosseous implantation.

Combination of Mustardè cheek advancement flap and paramedian forehead flap as a reconstructive option in orbital exenteration

PURPOSE

To describe a combinatory technique made of Mustardè cheek advancement flap and paramedian forehead flap as a reconstructive option after orbital exenteration.

METHODS

We retrospectively reviewed all patients who underwent orbital exenteration and subsequent reconstruction with this technique at our Head and Neck Department, Divisions of Ophthalmology and Otolaryngology, at San Raffaele Hospital, Milan, Italy.

RESULTS

Three patients were treated with the aforementioned technique, following orbital exenteration due to malignancies. All of them were affected by recurrent diseases arising from the ocular components or periorbital structures: one basal cell carcinoma and two squamous cell carcinomas. Excellent result was achieved considering skin texture and colour match, aesthetic results and intra and post-operative complications (only minor, surgically controlled haemorrhage and minimal dehiscence subsequent to defective healing occurred).

CONCLUSION

The proposed technique can be considered by the head and neck reconstructive surgeon as a good option in extended orbital exenteration.

Orbital exenteration: Symptoms, indications, tumour localizations, pathologies, reconstruction, complications and survival

OBJECTIVE

This study aims to evaluate malignant and benign diseases that lead to orbital exenteration.

PATIENTS

From December 1999 to September 2017, patients undergoing orbital exenteration were included in this retrospective study. All of them were evaluated on clinical symptoms, indications, tumour localizations, pathologies, reconstruction techniques, complications, recurrences, and survival.

RESULTS

Of the 205 patients enrolled in this study, 94 had a carcinoma, 73 melanoma, 9 a sarcoma, 14 some other malignant disease, and 15 a benign medical condition. Sixteen patients underwent reconstruction using a local eyelid skin flap (7.8%), 6 with a split-thickness graft (2.9%), 144 with a local flap (70.2%), and 25 with a microvascular graft (12.2%), whereas 14 patients did not undergo reconstruction (6.8%). The most common complications were wound dehiscences (25 cases), pain (17 cases), and partial flap necroses (13 cases). Moreover, 62% of the patients were treated with different facial prostheses or artificial eyes. Given these results, it appears that lymph nodes and distant metastases, as well as lymphatic invasion into vessels, perineural invasion, and non-cleared resection margins, seem to affect overall survival after orbital exenteration.

CONCLUSION

Different reconstruction techniques can be used to provide the patient with maximum functionality and aesthetics after orbital exenteration. Individual concepts should be discussed at the beginning of the treatment. Using primary reconstruction and providing osseointegrated implant-retained prostheses remain the gold standard.
