Factors associated with epiphora following orbital-sparing maxillectomy via modified Weber-Ferguson incision with lower blepharoplasty

PURPOSE

The aims of the study were to estimate the frequency of epiphora and to identify factors associated with epiphora after orbital-sparing maxillectomy via modified Weber-Ferguson incision with lower blepharoplasty (OSOSM-MWFILB).

METHODS

We performed a retrospective cohort study enrolling a sample derived from the patient population undergoing OSM-MWFILB over a 7-year period. The predictor variables were grouped into demographic, related health status, anatomic, tumor-specific, and therapeutic categories. The primary outcome variable was the presence of postmaxillectomy epiphora (PME). Descriptive, univariate, and multivariate regression mixed-effect models were computed.

RESULTS

The study sample was composed of 134 patients (46.3% females; 71.6% squamous cell carcinomas) with a mean age of 64.7 ± 12.2 years. There were 23 (17.2%) PME events, which were significantly associated with eight variables: male gender, poor general health (ASA III-IV), large vertical defect (Brown and Shaw's class III-IV), squamous cell carcinoma tumor type, big tumor size (T3-4), cervical lymph node metastasis (N1-2), long operating time > 3 h, and adjuvant radio(chemo)therapy in both univariate mixed regression and multivariate Cox hazards analyses. Healing of PME in irradiated patients was significantly delayed.

CONCLUSIONS

Ophthalmologic consequences in patients undergoing OSM-MWFILB require particular attention, especially in case of advanced tumors, multiple comorbidities, or long surgery with postoperative radio(chemo)therapy. This emphasizes the importance of appropriate cooperation between the surgeons and ophthalmic colleagues.

Melanotic neuroectodermal tumor of infancy: a rare presentation of an extremely rare neoplasm and diagnostic implications in Gombe, Nigeria

Melanotic neuro-ectodermal tumor of infancy is very rare. A unique neoplasm of the formative years, it typically involves the face or cranium; possesses rapid, expansile growth; presents as a firm swelling and displays a high rate of recurrence. Its rarity and unique features make diagnosis and management quite challenging. This challenge is increased in resource-limited settings like ours and with atypical presentation, such as was seen at our center, where patient presented with a bony hard swelling.

Ameloblastic carcinoma of the maxilla: A case report and an updated review of the literature

Ameloblastic carcinoma (AC) is an uncommon malignant odontogenic tumor that can be difficult to differentiate from ameloblastoma and can arise directly as an undifferentiated lesion or from a pre-existing benign lesion. The current study presents a novel case of primary maxillary AC and review the literature on AC of the maxilla. The review of the literature indicates that secondary tumors and posterior localization are associated with a higher tendency for recurrence and, often, multiple recurrences. Surgical therapy, eventually followed by radiotherapy, is the treatment modality most frequently applied, while the role of chemotherapy remains unclear. Several new cases of maxillary AC have been recently described in literature, making this pathology more frequent than previously considered; this is perhaps an indication of an increased diagnostic sensibility, rather than a real increase in the incidence of the disease itself.

Maxillary tumor in a child: An expected case of difficult airway

Craniofacial abnormalities in pediatric population fall under the category of expected case of difficult airway. We present here a case of large maxillary tumor in a 9-year-old girl where the relative difficulty was further compounded due to her noncooperation which was again expected from a child. Local anesthetic topicalization of airway followed by slow inhalational induction with gradually increasing sevoflurane, while maintaining her spontaneous breathing, we secured her airway using fiber optic bronchoscopy. The surgery and the extubation went uneventful. In conclusion a planned airway management using fiber optic bronchoscope after airway topicalization and sevoflurane induction is the ideal technique in an expected case of difficult pediatric airway.
