Delayed Diagnosis and Misdiagnosis of Lacrimal Sac Tumors in Patients Presenting with Epiphora: Diagnosis, Treatment, and Outcomes.

Epiphora, or excessive tearing, is a common symptom often attributed to benign conditions such as dry eye or nasolacrimal duct obstruction. However, it can also be an early indicator of lacrimal sac tumors, which are frequently misdiagnosed or diagnosed late due to their subtle presentation. This study aims to identify the clinical features that contribute to delays and misdiagnoses of lacrimal sac tumors in patients presenting with epiphora, with the goal of improving early detection and treatment outcomes. This retrospective study reviewed medical records from Taipei Veterans General Hospital between 2007 and 2023, focusing on patients who presented with epiphora and were later diagnosed with pathologically confirmed lacrimal sac tumors. Inclusion criteria were limited to cases that were initially misdiagnosed or had a delayed diagnosis, with imaging and clinical evaluations confirming tumor-related tear drainage obstruction. Patients with non-tumor causes of epiphora were excluded. Eleven cases of lacrimal sac tumors were identified, including two benign and nine malignant tumors. The average duration from symptom onset to diagnosis was 22.4 months. Common symptoms included epiphora (100%), discharge (54.5%), and hemolacria (18.2%). Subtle clinical signs, such as asymmetry in the medial canthal region and non-tender swelling, were frequently noted. Despite receiving appropriate surgical and adjuvant treatments, the impact of delayed diagnosis was significant. Two patients succumbed to tumor-related disease; one developed lung metastasis 12 years after diagnosis, and another experienced recurrence during a six-year follow-up after undergoing extensive exenteration, adjuvant chemotherapy, and radiotherapy. Lacrimal sac tumors can present insidiously with symptoms often mistaken for benign conditions, leading to significant diagnostic delays. Thorough history taking, meticulous physical examination, and timely imaging are crucial for early detection. Increased clinician awareness and a high index of suspicion for lacrimal sac tumors in patients with atypical epiphora are essential to improve prognosis and reduce the risk of severe outcomes.

Comparison of local flaps versus skin grafts as reconstruction methods for defects in the medial canthal region.

The medial canthal region features a complex three-dimensional and internal anatomical structure. When reconstructing a defect in this area, it is crucial to consider both functional and aesthetic aspects, which presents significant challenges. Generally, local flaps are preferred for reconstruction; however, skin grafts can be used when local flaps are not feasible. Therefore, we conducted a comparative analysis of surgical outcomes skin grafts when local flaps were not feasible, to determine which surgical method is more effective for medial canthal region reconstruction. Twenty-five patients who underwent medial canthal region reconstruction using skin grafts or local flaps from 2002 to 2021 were enrolled. Patient information was obtained from medical records. Five plastic surgeons evaluated the surgical outcomes based on general appearance, color, contour, and symmetry. Skin grafts were used in eight patients and local flaps were used in 13. Combined reconstructions were employed in four cases. Minor complications arose in four cases but improved with conservative treatment. No major complications were reported. Recurrence of the skin cancer was noted in two cases. All categories showed higher scores for the local flap compared to both skin graft and combined reconstruction; however, the differences were not statistically significant respectively. The choice of appropriate surgical methods for reconstructing defects in the medial canthal region depends on various factors, including the patient's overall health, the size and depth of the defect, and the degree of involvement of surrounding structures. When a local flap is not feasible, a skin graft may provide favorable surgical outcomes. Therefore, a skin graft can serve as a viable alternative for reconstructing the medial canthal region.

Medial Epicanthoplasty with the Skin Re-Draping Technique: Technical Refinements for Predictable outcomes.

The epicanthus is a common feature of the Asian eyes. A prominent medial epicanthal fold gives the impression of a blunted affect and the procedure for its removal, the medial epicanthoplasty, is a very commonly requested by Asian patients. This may be performed as an isolated procedure or more commonly in combination with the upper blepharoplasty. Many conventional medial epicanthoplasty techniques are based on skin flaps transposition and excisions, usually variations of the V-Y, W or Z-plasties (1-4). While these have been variably successful at correcting the epicanthal fold, the common problem is significant scarring in the medial canthal and lower eyelid regions (5-8). This is particularly problematic in Asian patients with greater tendencies for hypertrophic scarring and scar hypo or hyper-pigmentation (9). Recently, the skin re-draping method, designed with incisions limited within the margins of the medial canthus and precise and targeted disruption of the underlying fibromuscular tissues, has emerged as the preferred surgical technique for many Asian surgeons because of its effectiveness and superior aesthetic outcomes(6, 10-12). This technique delivers the most inconspicuous incisions and is advantageous because it is effective in eliminating epicanthal folds of various severities. Precise execution of this technique is difficult, given the complex 3-dimensional anatomy of the epicanthus. This paper presents a detailed explanation of surgical concepts of the skin re-draping epicanthoplasty and provide a step-by-step guide to performing this procedure in a safe and effective manner.

Reconstruction of Skin Defects in the Medial Canthal Region Using the Novel Hug Flap.

Various methods of reconstructing skin defects in the medial canthal region have been reported. We report 2 skin flaps for the upper and lower eyelids designed to reconstruct soft tissue defects in the medial canthal region based on the approach used for the orbit during surgeries for facial bone fractures. The skin flap was elevated without tension until it reached the defect. The skin flaps of the upper and lower eyelids were moved around the defect as rotational flaps and sutured. Two patients with skin defects in the medial canthal region after basal cell carcinoma resection were treated with this technique. No complications occurred, and good cosmetic and functional outcomes were obtained. This method can be used to reconstruct the eyelid with an elevated skin flap and is considered useful for repairing defects in the medial canthal region.

Monocanalicular versus bicanalicular annular intubation for treatment of lacrimal canalicular laceration

Purpose The aim of this study was to compare the safety and efficacy of monocanalicular and bicanalicular annular intubation for treatment of lacrimal canalicular laceration. Patients and methods This is a retrospective review of the medical records of 52 patients for whom primary repair of lacrimal canalicular laceration was done. The patients were allocated into two groups. Group I included 26 patients who underwent primary repair with monocanalicular intubation while group II included 26 patients who underwent primary repair with bicanalicular annular intubation. Three months after removal of the stent, negative fluorescein dye disappearance test and patency of the canaliculus on lacrimal irrigation were defined as anatomical success, while functional success was defined as absence of epiphora. Complications like stent prolapse, granuloma formation, and medial canthal deformity were recorded. Results Complete anatomical success was achieved in 18 (69.2%) patients in group I and in 21 (80.8%) patients in group II, with no statistically significant difference (P=0.594). Complete functional success was achieved in 20 (76.9%) patients in group I and in 22 (84.6%) patients in group II, with no statistically significant difference (P=0.683). In addition, there was no statistically significant difference between the two groups regarding the postoperative complications including punctum granuloma, punctum slitting, and medial canthal region deformities (P>0.05). Conclusion Both monocanalicular intubation and bicanalicular annular intubation were safe and effective for treatment of lacrimal canalicular laceration with no statistically significant difference regarding the anatomical and functional outcomes as well as postoperative complications.

Reconstruction of medial canthal region with orbicularis oculi myocutaneous flap: Our experience

Reconstructive surgery of the medial canthus is among one of the most challenging due to its complex anatomy and aesthetic features. In this area even the slightest deformity or asymmetry is noticeable. Reconstructive surgery of this anatomical region aims to restore the tissue defect ensuring an appropriate aesthetic and functional feature, restoring colour, thickness and consistency of the replaced tissue. Orbicularis oculi myocutaneous flap is an option to reconstruct the medial canthal region; in this paper the authors present their experience with orbicularis oculi myocutaneous flap in 10 patients with medial canthal malignant lesions. The patients' postoperative period was uneventful, the flaps usually showed some degree of temporary venous congestion during the first days after surgery, and any donor site morbidity was observed: no lid lag, ectropion, ptosis, or other eyelid deformity. This flap offers a similarity in texture, colour, and thickness to the recipient site and a negligible incidence of donor site morbidity, and it can be easily tailored to fit the shape of the soft tissue defect.

Warthin cyst of lacrimal sac: A rare presentation of a common tumor!

Warthin tumor is a common and benign salivary gland tumor comprising of 2-15% of all epithelial tumors of the parotid gland. The extra-parotid presentation is seen to be rare at sites like the eyelid, caruncle, and the lacrimal gland. In this study, we have reported an extremely rare case of Warthin cyst of the lacrimal sac in an 82-year-old male patient with swelling over the medial canthal region since the past 2 years.

Resolving trapdoor phenomenon without secondary procedure after forehead flap on medial canthal region.

Herein, we present a case of basal cell carcinoma in a 59-yearold woman. It presented with painless itchy, black, gradually enlarged patches which were easily bled under her left eye since three years ago. A dermatological examination of the left medial canthus region obtained hyperpigmented plaques (2x0.8x0.1 cm) with uneven skin texture, irregular borders, and erosion on the center of the lesion. We performed forehead flap technique surgery followed by eight-month monitoring, resulting in a satisfying outcome in both function and appearance. The thinning technique and adjusting the flap size from the forehead area to the medial canthus should be as thin as possible to avoid differences in skin thickness and post-reconstruction hypertrophic scars. A bulging appears on the surgical site a month after the procedure, known as the trapdoor phenomenon, on the 8th month of followup, the trapdoor phenomenon disappeared.

Standard and modified glabellar flap for medial canthus reconstruction following mass removal in three dogs and two cats

To describe the surgical technique and clinical outcomes of the glabellar flap and its modification for the reconstruction of the medial canthus following resection of tumors in three dogs and two cats. Three dogs (7-, 7-, and 12.5-year-old mixed breeds) and two cats (10- and 14-year-old Domestic shorthair) presented with a 7-13 mm tumor affecting the eyelid and/or conjunctiva in the medial canthal region. Following en bloc mass excision, an inverted V-shaped skin incision was made in the glabellar region (i.e., the area between the eyebrows in humans). The apex of the inverted V-shaped flap was rotated in three cases, whereas a horizontal sliding movement was performed in the other two cases to better cover the surgical wound. The surgical flap was then trimmed to fit the surgical wound and sutured in place in two layers (subcutaneous and cutaneous). Tumors were diagnosed as mast cell tumors (n= 3), amelanotic conjunctival melanoma (n= 1),andapocrine ductal adenoma (n= 1). No recurrence was noted in a follow-up time of 146 ± 84 days. Satisfactory cosmetic outcome with normal eyelids closure was achieved in all cases. Mild trichiasis was present in all patients and mild epiphora was noted in 2/5 patients, but there were no associated clinical signs such as discomfort or keratitis. The glabellar flap was easy to perform and provided a good outcome in terms of cosmetic, eyelid function, and corneal health. Postoperative complications from trichiasis appear to be minimized by the presence of the third eyelid in this region.

Glabellar superciliary bilobed flap for reconstruction of large medial canthus region defect

The aim of this study was to describe a series of patients who have undergone a medial canthal reconstruction with a glabellar superciliary bilobed flap. A series of 30 patients were included with medial canthal defects after excision of medial canthal tumour who underwent reconstruction using a glabellar-superciliary bilobed flap of adjoining skin and subcutaneous tissue. Eighteen procedures were performed under local anaesthesia. The remaining 12 cases were combined with major lid reconstruction and performed under general anaesthesia. Complete closure of the defect, aesthetic outcome, complications, and re-operations were all used as outcome measures. Primary closure of the donor site was achieved in all cases without wound dehiscence. In all cases, the cosmetic appearance was highly satisfactory to the surgeons and patients and there were no intraoperative complications. The glabellar superciliary bilobed flap is an effective, quick, simple, and single-stage technique for medial canthal region reconstruction. It provides excellent cosmesis and is associated with minimal complications. It can be modified according to the nature of the periorbital skin, location, size, and depth of the defect.

Hinged tarsal flap: A novel technique for canthal tendon reconstruction.

Reconstruction of the medial canthal region is challenging due to the complex regional anatomy. Options to reconstruct a medial canthal tendon sacrificed during tumour removal is limited. We present a novel surgical technique where hinged tarsal flap serves to substitute the canthal tendons. This is a retrospective consecutive case series of five patients that underwent canthal reconstruction using this novel technique between May and December 2020. Electronic patient records and medical photograph database were reviewed. Patient demographics, co-morbidities, location and histology of the lesion, size of the resultant defect, reconstructive technique and post-operative complications were noted. All patients had good eyelid stability with no malposition, lagophthalmos or exposure keratopathy. No or minimal distraction of the eyelid from the globe, good cosmetic outcomes and no troublesome watering was reported. No wound dehiscence, no sight loss and no further surgical intervention was warranted. Multiple techniques have previously been described to reattach the medial canthal tendon with silk or supramid sutures. Transnasal wiring, stainless-steel screw and mini-plate fixation are also described, but carry a high risk of complications and are unfamiliar amongst most oculoplastic surgeons. Our technique is quick and simple and utilises autogenous tissue without breaching the periosteum which acts as a natural barrier to tumour infiltration.Refashioning the canthal tendon aids to lengthen the remaining eyelid stump, reducing the horizontal length required to reform the newly constructed eyelid and facilitates the reconstruction.

Medial Canthus Reconstruction with the Paramedian Forehead Flap.

Background:The medial canthus represents the medial confluence of the upper and lower eyelid margins and plays an integral role in the lacrimal duct system. Various flaps have been utilized for the reconstruction of the lower eyelid in the medial canthal region. Our institution primarily utilizes the paramedian forehead flap for the reconstruction of medial canthus defects. Our study looked to evaluate the work of a single plastic surgeon and identify their postoperative outcomes.Methods:A retrospective chart review was conducted at Beaumont Health System, Royal Oak, for patients who underwent medial canthal repair by the lead surgeon between the years 2014 and 2018. Demographic data, operative details, complications, medical comorbidities, and patient outcomes were retrospectively gathered and analyzed.Results:A total of five patients were isolated. Patients underwent paramedian forehead flap medial canthal repair by the lead surgeon and were found to tolerate the procedure well. All patients had clinically viable flaps with aesthetically pleasing results.Conclusions:Utilization of the paramedian forehead flap leads to successful medial canthal repair with adequate coverage. Although the paramedian forehead flap requires three stages to complete, the procedure leaves patients with aesthetically pleasing results. In addition, the paramedian forehead flap has limited cases of ectropion. With the right expertise and patient population, the paramedian forehead flap can be highly successful in the repair of medial canthal defects.

Refined Concept of Motor Supply to the Medial Periorbital Area Relevant to Periorbital Surgery.

Mimetic muscles in the medial periorbital area have been thought to be innervated solely by the angular nerve. Recently, however, the upper medial palpebral branch and lower palpebral branch were reported as additional motor suppliers in this area. This study aimed to define all the motor nerve systems passing through the medial canthal area. Motor nerve branches that passed through the medial canthal region were identified and traced thoroughly from the parotid gland to their destinations under a surgical microscopic field in 74 hemifaces. The courses, anatomical positions of, and anatomical relationships between the angular nerve and the upper medial palpebral branch were observed. The upper medial palpebral branch and the angular nerve were found in all samples within a 3-mm to 6-mm area lateral to the intersecting point of the medial orbital rim and medial canthal ligament. The upper medial palpebral branch supplied the upper eyelid, whereas the angular nerve supplied the extraorbicularis muscles in the medial periorbital area. The medial pretarsal area of the upper eyelid was supplied solely by the pretarsal branches of the upper medial palpebral branch, which was formed by uniting three or four minor branches that traveled throughout the anterior cheek. Two separate motor nerve systems, the upper medial palpebral branch and the angular nerve, exist in the medial canthal area. The upper medial palpebral branch course along the medial orbital rim is considered as a facial nerve danger zone.

Risk Factors for Canalicular Injury After Mohs Micrographic Surgery.

There is a paucity of literature describing risk factors for canalicular injury (CI) during periocular Mohs micrographic surgery (Mohs). This study aimed to determine factors associated with CI after Mohs. This information may inform patient counseling and surgical planning. This case-control study compared subjects with canalicular injury after Mohs with subjects requiring ophthalmologic Mohs repair without canalicular injury. All subjects who had CI after Mohs were included in the control group. CI from other causes were excluded. Basal cell carcinoma was the most common etiologic tumor (p < .00001). Canalicular injury was associated with infiltrative, morpheaform, and/or micronodular-type basal cell carcinoma. Initial tumor location involving the medial canthus was not statistically different between cases and controls (32% vs 17%, p = .22). Having a final defect involving the medial canthus region was more likely in cases versus controls (55% vs 26%, p = .01952). Although most final defects involved the medial canthal region, a substantial number of tumors resulting in CI did not initially seem to involve the medial canthus. Surgeons cannot rely simply on anatomical location when assessing risk for CI, and anticipation of need for canalicular reconstruction is challenging.

A Novel Thunderbolt Z-Epicanthoplasty for Asians.

Although many epicanthoplasty techniques have been proposed, prominent hypertrophic scarring in the medial canthal region remains a problem. The aim of this study was to develop a novel design that has a less prominent scar with minimal tension. A total of 489 patients underwent thunderbolt Z-epicanthoplasty from July 2015 to April 2019, with or without blepharoplasty. A triangular myocutaneous flap was lifted from the upper part of the epicanthal fold. The surrounding area was dissected to remove the rigid connective tissue between the orbicularis muscle and the skin, which creates skin tension. A Z-shaped flap toward the inferomedial canthal portion was added to create space for the triangular flap to be transposed to change the straight incision into a curved zigzag incision (final scar in the shape of a "thunderbolt"), making the scar irregular and less conspicuous. Postoperatively, all patients were followed up for ≥ 12 months. Among the patients, epicanthus tarsalis (60.12%) and palpebralis (36.19%) were the commonest epicanthus types, followed by epicanthus supraciliaris (3.07%) and inversus (0.61%). The average preoperative intercanthal distance was 42.25 ± 1.66 mm. This distance decreased significantly to 37.14 ± 1.78 mm (average, 5.11 ± 0.21 mm; p = 0.036) at the 12-month postoperative follow-up. Mild cicatricial redness was observed in the medial canthal area in six patients (1.2%) during the early postoperative period. The redness diminished within 6 months postoperatively. All patients obtained natural and aesthetically pleasing results without prominent hypertrophic scarring or other complications in the medial canthal area. The thunderbolt Z-epicanthoplasty is safe and effective for treating medial epicanthal folds. It is potentially helpful in minimizing postoperative medial canthal scarring and can be applied to various types of epicanthal folds with long-lasting results.

Biplanar-pivoted V-Y Flap for Reconstruction of Medial Canthal Defects.

To determine the safety and effectiveness of a biplanar-pivoted V-Y flap design in reconstructing medial canthal defects of all sizes. Retrospective review of patients who underwent repair of medial canthal region defects with the biplanar-pivoted V-Y flap from January 2016 to May 2021. Variables collected included age, gender, surgical indication, defect sizes and location, flap(s) and/or graft(s) used, and follow-up time. Outcome measures included complications, patient satisfaction with cosmesis, ability to close the defect with minimal wound tension, and additional surgeries. Eighteen cases of medial canthal, nasal sidewall, and nasojugal fold area reconstruction were performed using a biplanar-pivoted V-Y flap in 18 patients. The cohort included 7 males and 11 females with a mean age of 72.4 years (range, 52-92 years) and mean follow-up time of 4.4 months (range, 1-14 months). Mean defect size was 2.0 × 1.4 cm (range, 0.5-5.5 cm). Eight patients received concomitant full-thickness skin grafts, five patients underwent simultaneous rotational flap repair, one patient underwent simultaneous nasoglabellar myocutaneous flap repair, and one patient received a simultaneous traditional, nonbiplanar V-Y plasty of the upper eyelid. All defects were closed with no wound tension. No cases of infection, hemorrhage, or wound dehiscence occurred during follow-up. Complications included mild ectropion (2 patients) and mild tip necrosis (1 patient). No patients elected for reoperation. No trapdoor deformity was observed. No patients underwent reoperation for local tumor recurrence. The extended mobility of the biplanar-pivoted V-Y flap provides excellent closure of defects involving the medial canthal region with minimal surgical complications.

Efficacy of Early Application of 1540 nm Non-ablative Fractional Laser and Silicones to Improve Post-epicanthoplasty Scars.

The combination of epicanthoplasty and blepharoplasty is a popular choice in Asians to acquire a pair of charming big eyes. However, the obvious scarring in the medial canthal area may result in unsatisfactory aesthetic outcomes. Recently, various laser treatments have been used to deal with scars had achieved detectable improvement, but only a few studies investigating the efficacy of lasers used in post-epicanthoplasty scarring were developed. A total of 70 participants who underwent Z-epicanthoplasty were enrolled in this prospective clinical trial and were randomly assigned to the groups of 1540nm non-ablative fractional laser (NAFL) combined with silicones treatment and silicones alone treatment. The NAFL-exposure in the treated group was additionally applied to the medial canthal area on day 21 postoperatively, compared with the participants in the control group who had only been treated with the daily usage of silicone sheets for 12 hours and silicone gels twice for 5 months after scab had fallen from the skin. Scar evolution was performed by patient and observer scar assessment Scales (POSAS) and visual analogue scale (VAS) for 21 days, and 6 months postoperatively. 64 participants have completed the entire follow-up process. The scar recovery was statistically detected in treated group compared with the control group at 6-month postoperatively assessed by POSAS, especially in pliability of scars. Furthermore, the VAS evaluations showed superior satisfaction in treated group. The early treatment of NAFL combined with silicones has improved scar formation in medial canthal region after epicantholplasties efficiently.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Commentary: A technical revisit to the glabellar flap.

We have read an interesting article by Balchev et al. published in the current issue of IJO. They included 15 patients who were followed up over 36 months. The authors have described the use of glabellar flap (GF) to reconstruct medial canthal region defects. They have categorized the medial canthal region into the upper, medial, and lower zone in reference to the medial canthal tendon. They used V-Y glabellar rotation, advancement, or combined transposition flap techniques. By definition, the glabella is a region between the eyebrows that has potential skin to reconstruct surrounding areas like the medial canthus and nose.[1] The glabellar myocutaneous flap is a simple, safe, and effective procedure that provides anterior lamellae and vascular supply to the reconstructed region.[12] The advantages being similar skin color, texture, and thickness with minimal postoperative flap shrinkage or contracture.[123] Moreover, the vascular supply leads to faster healing with minimal collateral damage. Maloof and Leatherbarrow[4] (2000) provided a detailed description of the GF. They conceptualized the idea of anatomical and surgical medial canthus, the latter being much larger in area. The surgical medial canthus extended from the subbrow region (superior) to the upper cheek (inferior) and medially up to the midline over the nose. They believed that any reconstruction of surgical medial canthus could be performed using a glabellar V-Y flap. The critical factors in preoperative planning of GF include[4]: Size, depth, and location of the defect Orientation and alignment of the V-Y flap Depth of the medial canthus or nasal bridge prominence Age and skin texture of the patient. The smaller, shallower, and medial defects have favorable outcomes. The prominent nasal bridge or deep medial canthus will need a longer flap to reach up to the lateral edge of the defect. Younger patients have tighter skin that may have intraoperative implications. Skin marking is a vital part of the GF harvesting process. After the surgical excision of the lesion and determining its tumor-free margins, a surgical marker pen is used to draw the triangular or rectangular GF. The flap size depends on the size of the defect, distance from the glabella, and the depth of the medial canthus.[1234] The first arm of the V-shaped GF, arises tangentially from the superolateral edge of the defect, passes superomedial toward the midline apex. The second arm (preferably curved in shape) is fashioned at an acute angle, and its length is kept slightly longer to accommodate the bend of flap tissue [Fig. 1]. The flap should have a broad base for better vascular supply. The dissection should be limited to the skin and subcutaneous tissue, avoiding the involvement of corrugators and procerus muscles. The suture fixation of the flap base to the underlying periosteum prevents traction and preserves canthal concavity. The donor site should be closed in two layers—the deeper muscular layer (4-0 or 5-0 absorbable sutures) and the skin with 4-0 or 5-0 prolene or nylon (preferably horizontal mattress sutures). For larger defects, the extended, modified advancement flap, rotational flap, or bilobed GF can be used.[145]Figure 1: A glabellar flap fashioned for the reconstruction of left medial canthus lesion showing the first and second arms with a broad baseThe complex scenarios that may compromise the outcomes of GF include[4]: Young patients with tight forehead and facial skin Very deep medial canthus Dense hairs in-between eyebrows (synophrys) Large and irregular defect extending more laterally or inferiorly. The limitations of GF include consecutive midline forehead scar, medialization of the eyebrows, lymphedema, and flap uptake-related complications (necrosis, infection, etc.).[45] Nevertheless, the GF and its modifications constitute a simple, reproducible, and efficient technique providing excellent skin color match with satisfactory aesthetic and functional outcomes.[3]

Primary basaloid squamous cell carcinoma of the parotid gland mimicking metastasis of basal cell carcinoma of the contralateral periorbital region: case report

Basaloid squamous cell carcinoma (BSCC) in the head and neck area is extremely rare. World Health Organization defined BSCC as a high-grade variant of squamous cell carcinoma composed both of basaloid and squamous components. Due to its histologic similarity to other parotid gland malignancies it can be easily misdiagnosed. We report first case of BSCC arising from parotid gland in Europe and second in the world literature. A 72-year-old female patient was referred to the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University in Poland due to the tumor arising from the right parotid gland. Patient had history of multiple excisions of recurrent basal cell carcinoma (BCC) of the left periorbital region. We performed total parotidectomy with facial nerve preservation. Postoperative radiotherapy (PORT) was carried out, and the patient received 70 Gy in 30 fractions on the parotid gland area due to the fact that the tumor adhered to the facial nerve trunk and branches, additionally 60 Gy on the neck area in I, II and III levels. To distinguish the tumor of the parotid gland from the possible metastasis from BCC of the left medial canthal region previous histopathological slides were also reexamined and compared with histopathological examination of removed parotid gland tumor. Histological examination confirmed a rare case of BSCC arising from the parotid gland. 14 months of the follow up did not show local recurrence or distant metastasis.

Eyelid Reconstruction: An Algorithm Based on Defect Location.

Eyelid reconstruction is a complex topic. This review looks at articles from 1990 to 2018 on eyelid reconstruction that had at least 10 patients and a mean 6 month follow-up. The authors present the results of our findings and propose an algorithm to guide the surgeon in choosing the best technique based on location, size, and lamella. Defects less than 1/3rd of the upper or lower eyelid may be closed primarily. Anterior and posterior lamella defects of the lower eyelid greater than 1/3rd in size should be reconstructed with a double mucosal and myocutaneous island flap. Those greater than 50% in size should be recreated with a Tripier flap for the anterior lamella and conchal chondroperichondral graft for the posterior lamella. For total lid reconstruction, a Fricke flap is best for the anterior lamella and the tarsoconjunctival free graft/lateral orbital rim periosteal flap is best for the posterior lamella. Fullthickness defects between 1/3rd and 2/3rd in size of the upper eyelid should be reconstructed with a myotarsocutaneous flap and those greater than 2/3rd should be reconstructed with a Cutler-Beard flap for the anterior lamella and auricular cartilage for the posterior lamella. For the medial canthal region, the island pedicle and horizontal cheek advancement flap is recommended for the anterior lamella and a composite upper lid graft for the posterior lamella. For the lateral canthal region, a bilobed flap is recommended for the anterior lamella and a periosteal flap for the posterior lamella.
