Myomucosal island flaps for oropharyngeal reconstruction.

The oropharynx represents one of the most challenging areas to reconstruct for the head and neck surgeon. The buccinator myomucosal island flaps pedicled on the facial artery [tunnelized facial artery myomucosal island flap (t-FAMMIF)] or the buccal artery [buccal artery myomucosal island flap (BAMMIF)] are an ideal reconstructive option for moderate size defects measuring up to 8-9cm. Two fresh specimens have been used to show the step-by-step surgical technique of both island flaps. Design and flap extension, dissection plane, identification of the vascular pedicle, flap rotation and insetting are described. Reconstructive indications and the pros and cons of each one are discussed in this article. Myomucosal island flaps represent a very useful and versatile option for the functional reconstruction of the oropharynx. A detailed knowledge of the vascular anatomy of the cheek is key to obtain a large flap while minimizing the risk of complications.

Bonebridge® bone conduction implant. Hearing outcomes and quality of life in patients with conductive/mixed hearing loss.

PURPOSE: The aim of this study was to analyze the hearing outcomes and quality of life in a series of 52 patients affected by conductive or mixed hearing loss and treated with Bonebridge®. METHODS: 52 of 71 patients implanted with Bonebridge® between October 2012 and January 2022, were included in the study. We compared the air conduction thresholds at the frequencies 500, 1000, 2000, 3000, 4000 Hz, the SRT50% and the World Recognition Score at an intensity of 50 dB with and without the implant. The Abbreviated Profile of Hearing Aid Benefit (APHAB) was employed to assess the quality of life of patients. RESULTS: The liminal tone audiometry (free field) pure tone average for air conduction after 6 months with the implant was 35.12 dB, obtaining a mean gain of 31.83 dB. With Bonebridge®, the mean SRT was 34.17 dB, whereas before the surgery no patient achieved 50% of correct answers at a sound intensity of 50 dB. The world recognition score at 50 dB changed from 11% without the implant to 85% with it. We observed one case of implant failure and one case of implant exposure. The APHAB questionnaire showed an improvement after implantation in practically all the subscales. CONCLUSIONS: The hearing outcomes and the subjective benefits reported by patients obtained in our study are similar to those published in the literature. Bonebridge® represents an excellent method for the rehabilitation of patients with conductive and mixed hearing loss, showing a low rate of complications.

Right colonic interposition for severe pharyngoesophageal stricture in head and neck patients: A feasible rescue strategy after multiple failed reconstructive options.

Severe pharyngeal stricture is an uncommon complication that may occur afer laryngectomy especially in irradiated patients. Its management is a challenge and high risk of recurrence after reconstruction exists. We present two patients with severe end-stage pharyngoesophageal stricture after several failed attempts of reconstruction with regional and free flaps, in which a right colon transposition was performed. Twenty days after surgery both patients were able to tolerate an oral diet, and no minor or major complications were observed. Right colonic transposition may be a valid option for secondary pharyngeal reconstruction if other less invasive methods such as regional or free flaps have failed to restore the pharyngoesophageal continuity or if the inferior location of stricture makes a tension free anastomosis impossible.

Cervicofacial surgery and implantable hearing device extrusion: management of challenging cases.

OBJECTIVE: To describe our management of implantable hearing device extrusion in cases of previous cervicofacial surgery. METHODS: A review was conducted of a retrospectively acquired database of surgical procedures for implantable hearing devices performed at our department between January 2011 and December 2019. Cases of device extrusion and previous cervicofacial surgery are included. Medical and surgical management is discussed. RESULTS: Four cases of implant extrusion following cervicofacial surgery were identified: one involving a Bonebridge system and three involving cochlear implants. In all cases, antibiotic treatment was administered and surgical debridement performed. The same Bonebridge system was implanted in the middle fossa. The three cochlear implants were removed, and new devices were implanted in a more posterior region. CONCLUSION: Previous cervicofacial surgery is a risk factor for hearing implant extrusion. The middle fossa approach is the best option for the Bonebridge system. Regarding the cochlear implant, it is always suitable to place it in a more posterior area. An inferiorly based fascio-muscular flap may be a good option to reduce the risk of extrusion.

Early T1-T2 stage p16+ oropharyngeal tumours. Role of upfront transoral robotic surgery in de-escalation treatment strategies. A review of the current literature.

Human papillomavirus is responsible of approximately 70% oropharyngeal tumours and is related with more favourable outcomes. It has led to an increasing interest for de-escalation treatment strategies such as Trans Oral Robotic Surgery (TORS). A literature review was performed searching for the role of TORS as de-escalation modality of treatment in patients with p16 positive oropharyngeal squamous cell carcinoma (OPSCC). Special attention was paid to the potential advantage offered by TORS in reducing adjuvant radiation therapy. Six questions were formulated. 67 studies were selected. Several trials analysing the role of upfront TORS to treat early stage p16+ OPSCC and the possibility of reducing the adjuvant radiotherapy were founded. A lot of studies based on the experience of single centres show promising results. Nevertheless to date no definitive data can be extrapolated. The continued investigation of this line of de-escalation therapy with randomized prospective clinical trials is needed.

Pseudo mastoid obliteration with conchal cartilage may be a safe alternative technique for cochlear implantation in canal wall down mastoidectomy with large meatoplasty.

OBJECTIVE: Safe cochlear implantation is challenging in patients with canal wall down mastoid cavities, and the presence of large meatoplasties increases the risk of external canal overclosure. This paper describes our results of obliteration of the mastoid cavity with conchal cartilage as an alternative procedure in cases of canal wall down mastoidectomy with very large meatoplasty. METHODS: The cases of seven patients with a canal wall down mastoidectomy cavity who underwent cochlear implantation were retrospectively reviewed. Post-operative complications were analysed. The mean follow-up duration was 4.5 years. RESULTS: There was no hint of cholesteatoma recurrence and all patients have been free of symptoms during follow up. Only one patient showed cable extrusion six months after surgery, and implantation of the contralateral ear was needed. CONCLUSION: Pseudo-obliteration of the mastoid cavity with a cartilage multi-layered palisade reconstruction covering the electrode may be a safe alternative in selected patients with a large meatoplasty.

Endoscopic reconstruction of large anterior skull base defects with opening of the sellar diaphragm. Experience at a tertiary level university hospital.

BACKGROUND: The indications for expanded endoscopic transnasal approaches continue to increase, with more complex skull base defects needing to be repaired. This study reviews the management of large anterior skull base defects with opening of the sellar diaphragm. METHOD: A prospective analysis of endonasal endoscopic surgery carried out at Son Espases University Hospital between January 2013 and December 2018 was performed. The analysis included only the cases with a significative intra-operative cerebrospinal fluid leak. In all cases, reconstruction was performed by combining the gasket seal technique with a pedicled mucosal endonasal flap. RESULTS: Twenty-eight patients were included. The mucoperiosteal nasoseptal flap, the lateral wall flap and the middle turbinate flap were used in 13, 8 and 7 patients, respectively, combined with the gasket seal technique. One case of post-operative cerebrospinal fluid leak was observed (3.57 per cent). CONCLUSION: The combination of a gasket seal with an endonasal mucosal flap is an excellent technique for repairing large anterior skull base defects.

The Bonebridge active bone conduction system: a fast and safe technique for a middle fossa approach.

BACKGROUND: The transmastoid pre-sigmoid approach is always the preferred choice for implantation of the Bonebridge active bone conduction system in patients with a normal anatomy. When an anatomical variant exists or a previous surgery has been performed, a retrosigmoid approach or middle fossa approach can be performed. METHODS: The preferred surgical technique for a middle fossa approach is described. A 14 mm drill head (Neuro Drill) was used to create the bed at the squamous portion of the temporal bone. Surgical time and complication rate were analysed. RESULTS: The surgical time was shorter than 30 minutes in all cases, and only 14 seconds were needed to create a 14 mm bone bed. No complications were observed during the follow-up period (6-45 months). CONCLUSION: Use of the Neuro Drill for the middle fossa approach is an easy technique. It significantly decreases the surgical time, without increasing the complication rate.
